PLO - Palestine Liberation Organization :: essays research papers fc

History Palestinian Liberation Organization 1. Can the Palestine Liberation Organization (PLO) reasonably guarantee to be 'the sole, genuine agent of the Palestinian individuals.'? The PLO was set up in 1964 by an Arab League choice accordingly to developing indications of Palestinian agitation. The Palestinians wanted to recover the grounds involved by Israel, which they felt had a place with them, as said in the Bible. In 1964 the Arab states made the Palestine Liberation Association (PLO). While it should speak to the Palestinians, as a general rule it spoke to the perspectives on President Nasser of Egypt, who guided the development of the PLO. Its first chief made wild and flighty dangers to drive Israelis into the ocean, and had nearly nothing support among Palestinians for he was viewed as a manikin of the Egyptians. In the 1960s Palestinian understudies started to frame their own associations autonomous of control by Arab governments (in spite of the fact that the Syrians, Libyans, also, Iraqis kept on financing and control specific gatherings). Yasser Arafat established an autonomous Palestinian-run party called Fatah. He is said to have the sponsorship, for the majority of the ongoing past, of about 80% of the Palestinian individuals. The situation of the Arab governments was that a PLO under Arab League management would be the most ideal method of fulfilling the requests made by a developing Palestinian national cognizance. Additionally, it was felt that through such an association Arab governments could control Palestinian political exercises. Ten years after its establishing, the PLO was raised to the status of government. What's more, in 1988, the PLO's status was to be raised once more, this time to a state in a state of banishment. After a few arrangements, Arafat turned into a Fear based oppressor pioneer and manager of self-rule in the West Bank and the Gaza Strip. In the 1967 Six Day War, the Arab armed forces did severely against Israel, losing 67,000 square kilometers of land. Palestinians came to accept that in the event that they were ever to have their property, they would need to do it themselves. After the 1967 war, the circumstance changed definitely. The opposition exercises of different guerrilla associations, specifically the Al-Fatah and the PFLP, picked up the expanding backing of the Palestinians. With Arafat in charge from 1969 and an opposition arranged initiative, the PLO was progressively compelling and assumed a focal job in activating the Palestinians and in growing its premise of help both at the nearby and universal level. The PLO turned into an umbrella association for the different guerrilla gatherings. This expansion in help was made conceivable in light of the Al-Fatah's capacity to access to the developing quantities of volunteers from displaced person camps which were newly swollen because of the 1967 war.

Essay Sample on Changing The Notions of Change

Article Sample on Changing The Notions of Change Change is a progressing procedure that includes the rotation of one state to another. Be that as it may, the manner in which people react to that change is to a great extent dictated by their point of view, of how they see and comprehend things just as their underlining mental, social and ideological developments. The procedure of progress might be unconstrained and it includes pre-change, impetus and results. In reading â€Å"Looking for Alibrandi† by Melina Marchetta, this idea of progress is molded as far as the focal character Josie’s experience and exercises. Not just that, this all inclusive topic is additionally recognizable in writings as differing as â€Å"The Door† by Miroslav Holub, â€Å"American History X† by David McKenna, â€Å"My father started as a god† by Ian Mundie and â€Å"Student discovers illumination in a grasp with her heritage†, an article out of the SMH composed by Cynthia Banham. All in all, different authors use a scope of printed frames just as elaborate procedures to pass on the ideas of progress. At first, the hero Josie of â€Å"LFA† takes a melancholic position towards her situation in the general public. Her brain research is influenced by her frailty and disarray towards her social character. â€Å"As far as the Italians were concerned, we weren’t totally one of them†¦We weren’t totally Australians.† The utilization of â€Å"we† carries the peruser closer to Josie by talking as though the responder has a place with her own social setting, subsequently accomplishing sympathy. Josie’s discernments and belief system is molded by her social foundation â€Å"At St Martha’sbrains didn’t consider a lot, cash esteem and what your dad accomplished professionally counted†¦it causes me to feel that I will never be a piece of their society.† First individual portrayal is utilized in consistence with the admission style direct discourse which viably makes compassion as Josie never lies about her internal sentimen ts. Being ill-conceived and having a place with a lower-white collar class, Josie’s belief system is firmly influenced by the microcosm of a rich school society. Her desirous tone passes on her self-discriminative emotions â€Å"Being stuck at a school ruled by rich individuals, rich parents†¦Anglo Saxon Australians who I cannot see as having an issue in the world.† As can be seen, Josie’s starting confounded viewpoint is adequately molded by her mental, social and ideological developments. Advancing from the pre-change stage, Josie faces numerous impetuses started without anyone else and outside impacts. Her first experience includes the passage of Michael Andretti, her tragically deceased dad into her life. Be that as it may, being disregarded for a long time, she holds a commonly angry and confounded disposition towards his quality. Her rash and furious tone shows this:† How might you venture to feel that I need to be in your life!† This be that as it may, differentiations to a later occasion where she uses the outside impetus and starts it as her own after she looks for Michael’s help with the Carly Bishop struggle. At the point when Michael safeguards her, she concedes that â€Å"For a couple of moments I knew how it felt to stroll close by one’s dad, it was an extraordinary feeling.† her tone changes as she is not, at this point confounded subsequently demonstrating change, when self perpetrated may prompt positive outcomes. Another occasion which adjusts Josie’s point of view is the yearly walkathon where she ignored her obligations as the bad habit commander of school to lead the youngsters. Her confession booth tone passes on that she is developing from the exercise â€Å"Deep down I realized I was wrong†¦I think my liberation started at that moment.† Later on the day, she likewise finds reality with regards to her captaincy that she was in actuality casted a ballot the school commander. Her underlying negative view about her social standings in the school takes a positive turn â€Å"and I was casted a ballot the school skipper. Socially we weren’t as crappy as we suspected we were.† Probably the most grounded impetus which impact Josie is those of John Barton’s passing. It adequately goes about as the end result of the novel, where the peak settle all the contentions. During the occasion Josie’s desirous point of view on the rich and fruitful is tested â€Å"How might he venture to murder himself when he’s never had any worries?† Her nervousness is settled by her dad that â€Å"A individual doesn’t fundamentally must be cheerful on the grounds that they have social standings and material riches, Josie.† John’s passing is lamentable however it permits Josie to develop from her nað ¿ve ideological viewpoint on the rich microcosm of the general public. It very well may be consequently contended that change, regardless of whether started without anyone else or outer powers will permit individuals to emphatically advance. Each change has its results. Josie’s confounded point of view on her legacy is viably settled by â€Å"I’m an Australian with Italian blood streaming quickly through my veins.† Her difference in tone likewise shows the difference in context when she at first taunts religion by perusing a â€Å"hot pants† magazine in religion class. â€Å"It’s loaded with rubbish†¦do you feel that they have a segment named â€Å"are you a decent Christian†?† the nað ¿ve and haughty tone changes to a substantially more genuine and develop one â€Å"I’ll put stock in god and I won’t let any congregation decides remove that from me.† To permit changes to be effectively recognizable, Marchetta utilizes ordered portrayals where Josie’s life is told through the time of one year. â€Å"You know, a magnificent thing transpired when I thought about back my year, â€Å"one day† came on the grounds that I at long last unde rstood.† Marchetta’s utilization of Intertexuality successfully features Josie’s liberation â€Å"I’m not seventeen any longer, the seventeen where Janis Ian sang about where one learns reality, however what she neglected to make reference to is that you continuing learning facts after seventeen and I need to continue learning certainties until the day I die.† This hence passes on the thought that change is a progressing procedure, not simply from guide A toward B. Miroslav Holub’s verse â€Å"The Door† portrays the change as a procedure. The sonnet starts with the basic â€Å"Go and open the door† which effectively urge the responders to investigate change. â€Å"The door† represents the obstructions which encase and limit people’s point of view to those of present. It additionally represents a section into another universe of potential outcomes to increase another viewpoint. The utilization of â€Å"Maybe† in italics and its reiteration passes on that change has no surenesses, however its outcomes are subject to the person’s point of view and translations â€Å"Maybe outside there’s a tree, a wood†. Be that as it may, the utilization of an idealistic tone convinces the peruser that â€Å"If there’s a haze, it will clear.† The utilization of metaphorical language portrays the most noticeably awful prospects of progress â€Å"even if there’s just the dimness ti ckling, even there is just the crying wind† then forms to a peak with a reductive sentence structure â€Å"even if Nothing Is there† This method adequately powers the responder to peruse more slow, until the last refrain, the coda which contains the subject of the sonnet â€Å"at least there’ll be a draught†. It shows that whatever the conceivable outcomes, regardless of whether fortunate or unfortunate, individuals will at last profit by change. The comparative thoughts are passed on in â€Å"LFA† where the procedure of Josie’s change starts with snags, however she can effectively grasp change subsequently guiding it to the best outcomes, seen through her liberations. Comparative ideas of progress are spoken to in the film â€Å"American History X†. The Protagonist Danny is sibling to the pioneer of an extremist group (D.O.C.), Derek who is detained for the slaughtering of a dark American. At first, Danny lives in an irksome piece of the America where racial pressure is wide spread. Normally, his mental, social and ideological development is based around white mastery over the ethnic gatherings. His preference sees be that as it may, fundamentally changes as Derek is discharged from jail years after the fact. His encounter with Danny portrays his involvement with the jail along these lines featuring that not one race is progressively predominant. There are numerous methods in the film that shapes significance for change. The story, much like â€Å"LFA† is described in sequential request as an article. It successfully shows the procedures of progress as composed and organized. It additionally permits the responders to observe the points of view of before â€Å"Blacks, Hispanics, Asians, those risks are contaminating our delightful country† and an after â€Å"we must be open minded of each other’s contrasts, what isolates us isn't the way of life, however great and evil.† Symbolism of insignia is exceptionally viable in demonstrating Derek’s beginning extremist viewpoint towards the ethnics. Be that as it may, later as he attempts urgently to wash it off, it stays as it was inked indicating Derek’s feelings of disdain for being an extremist. Changing point of view is apparent in Danny’s demonstration of ripping the Nazi banners off his room, which represents his development away from the Nazi belief system. Intertexuality is utilized to feature Danny’s change of point of view. Close to the finish of his film he cites from Abraham Lincoln to pass on his new points of view â€Å"We are not foes, yet companions, we should not be adversaries, however interests may have stressed, it must not break our obligations of warmth. The spiritualist ropes of memory will grow when again contacted as definitely they will be by the holy messengers of our nature.† Technique of end result is employe

The Namesake

The Namesake Last Friday, I went to the AMC Cambridge to see the big-seen adaptation of The Namesake. The film was based on the fantastic novel by Jhumpa Lahiri. Lahiri was awarded the Pulitzer Prize in 2000 for her collection of short stories Interpreter of Maladies. Jhumpa Lahiri is no stranger to MIT. She spoke here as part of the MIT Writers Series and visited campus again as part of a symposium on Asian Diasporas and New Transnational Cultures. Video of the latter is available in the Language Learning and Resource Center (LLARC) Things the movie got right: Ashoke Ashimas first years of marriage in America; the Gangulis trip to India Thing the movie didnt get right: Gogol Moushumis train station scene Thing the movie didnt get at all: Nikhils Yale years these were so good, why did you omit them?! Argh Another cool connection: Ashoke (below, with camera), who gave his son Gogol (below, without White Castle hamburger) his name, came to America to research at MIT. Nice. The event was sponsored by MIT South Asian American Students (SAAS), who purchased tickets for us in advance and offered them at half the cost. Many thanks!

Small Boat Cooling System Operation and Maintenance

There are two common engine cooling schemes in small vessels. Raw water cooling circulates seawater through the engine block directly, while closed loop cooling utilizes a heat exchanger to isolate the engine coolant from seawater which carries the excess heat out of a vessel. Both systems have similar components and operation. The more complex of the two systems is actually two simple cooling loops in series. The concepts are easy to understand and so are the fixes to common problems. Raw Water or Open Cooling We will follow the path of the water from the sea into the intake which is fitted with a valve called a seacock to close the opening if a coolant line fails. These connections are large and will put several hundred gallons per minute into your hull if they fail. The cooling water passes through a strainer which should be checked each day. Emptying this little basket of garbage is very important since it will impede the flow to the engine which could cause damage. Expensive damage. Next the seawater travels through a hard piped line or sometimes flexible hose to the cold side of the engine cooling system. Any soft lines should be secured with double band clamps on each connection, they should be checked very often for failure or wear. On its journey through the engine the cool sea water absorbs heat by passing through small channels cast into the engine components. These channels give plenty of surface area where heat can be absorbed but they do have drawbacks like clogging and freezing in cold weather. As the seawater exits it passes though a thermostat which can be a automotive spring type device or a sensor connected to a automatic gate valve. If the water is below the ideal temperature threshold for the engine cooling water by passes the engine until heat removal is required. A cold running engine is bad for the machinery and the efficiency of an engine. The cooling water and exhaust gasses are combined in a wet exhaust system where they exit the vessel. If exhaust is aerial then cooling water passes through another seacock to exit the hull. Closed Loop Cooling This type of cooling is very similar to raw water cooling except in place of an engine theres a heat exchanger. Basically a tube within a tube that transfers heat without allowing liquids to mix. The coolant circulates on the engine side while raw seawater circulates on the heat exchanger side. Other than this important point all operations are similar. Pros and Cons of Open and Closed Systems Open Pros: simple and well known, no chemicals, if hard piped the only maintenance is cleaning the strainer. Cons: Prone to clogging with debris, pure water allowed to freeze in engine passages will crack the engine block, in some environments the inside of the system can become home to mussels and barnacles. Closed Pros: Much less time to bring a engine to a stable operating temperature, less temperature fluctuation increases fuel and power efficiency, winterizing tasks and cold damage are minimized, if a clog appears it will be in the heat exchanger side which can be easily serviced; a clog in an engine passage requires disassembly excess heat can be used for space heating. Cons: Marine coolant is expensive and many systems have a high capacity, potential to leak coolant into the surrounding water, additional anodes must be placed and monitored for signs of corrosion. Whats the Best Marine Cooling System? The answer depends on you location and operations. Fouling and clogs are the biggest issue for most operators and local knowledge works best for these situations. If you must choose one type of system over another and everything else seems equal, then take a look at the anti-fouling paint used in your area. If it is meant to aggressively prohibit growth of marine life, then you should consider a closed system to reduce the risk of damage. How to Flush Your Work Boat Cooling System While there are a couple thousand large ships in the global merchant fleet, there are perhaps a couple hundred thousand smaller work boats. Operators of these boats are often also owners and to keep costs down some go without professional maintenance services. If you choose this approach it will save money, although it does increase the risk of damage due to human error. Working carefully and understanding some of the underlying concepts of you equipment will assure the job is done correctly while still saving money. Many of us have entered this profession through the world of small boats. Those long days spent at the marina washing recreational boats for extra spending money turned into more complex jobs. Soon, those little electrical and plumbing jobs earned a few dollars, and hopefully a good reputation. Then one day, while crammed under the helm station of a ship, the thought crosses your mind; how did I get here? Formal education  is available for these jobs and many excellent schools will give you a comprehensive understanding of the systems of any size vessel.

Chuang Tzu s Basic Writings Essay - 1558 Words

Chuang Tzu’s Basic Writings, with his idea of â€Å"the way† which is effortless and ineffable, seem to suggest a minimalist take on government. The Daoist philosophy present in the text has no room for organized hierarchy or unified morality in the understanding of the world. This leaves no room for government whose laws and bureaucracy are based on codified morality and hierarchy. The government must also allow its citizens to practice the wu-wei, which means the government would have to allow individual freedom. Thus the only suitable form of government following â€Å"the way† would be a limited structure emphasizing individual morality—essentially a libertarian form of government. There is a lack of hierarchy in Chuang Tzu’s Daoism due to the belief in the indistinguishable position of the individual to the rest of humanity and humanity to all the world. This is evident in â€Å"The Dream and The Butterfly† in which Chuang Tzu shows that the perspective of a human is no truer than the perspective of a butterfly. In the fable, Chuang Tzu’s questioning of which organism is the reality and which is the dream blurs the distinction between humanity and nature. This is consistent with Chuang Tzu’s belief that humanity is one with nature, meaning that human government should reflect the form of hierarchy present in the natural world. Such a belief in the most natural sense of hierarchy would at first suggest that â€Å"the way† is a path of egalitarianism; however, this belief that, in nature,Show MoreRelatedReligion Essay1759 Words   |  8 Pagesearly Taoist book, including the Chuang Tzu and the Lao Tzu, is in fact an anthology of work by many writers.

We will write a custom essay sample on Design of a New Security Protocol Using Hybrid Cryptography or any similar topic only for you Order Now Sakthivel School of Computing, Sastra University, Thanjavur – 613401, Tamil Nadu, INDIA. ABSTRACT A Computer Network is an interconnected group of autono mous computing nodes, which use a well defined, mutually agreed set of rules and conventions known as protocols, interact with one -another meaningfully and allow resource sharing preferably in a predictable and controllable manner. Communication has a majo r impact on today? s business. It is desired to communicate data with high security. Security Attacks compromises the security and hence various Symmetric and Asymmetric cryptographic algorithms have been proposed to achieve the security services such as Authentication, Confidentiality, Integrity, Non-Repudiation and Availability. At present, various types of cryptographic algorithms provide high security to information on controlled networks. These algorithms are required to provide data security and users authenticity. To improve the strength of these security algorithms, a new security protocol for on line transaction can be designed using combination of both symmetric and asymmetric cryptographic techniques. This protocol provides three cryptographic pr imitives such as integrity, confidentiality and authentication. These three primitives can be achieved with the help of Elliptic Curve Cryptography, Dual -RSA algorithm and Message Digest MD5. That is it uses Elliptic Curve Cryptography for encryption, Dual -RSA algorithm for authentication and MD-5 for integrity. This new security protocol has been designed for better security with integrity using a combination of both symmetric and asymmetric cryptographic techniques. Keywords: Network Security, Elliptic Curve Cryptography, Dual-RSA, Message Digest-5. 1. INTRODUCTION Curiosity is one of the most common human traits, matched by the wish to conceal private information. Spies and the military all resort to information hiding to pass messages securely, sometimes deliberately including misleading information [12]. Steganography, a mechanism for hiding information in apparently innocent pictures, may be used on its own or with other methods. Encryption fundamentally consists of scrambling a message so that its contents are not readily accessible while decryption is the reversing of that process[14]. These processes depend on particular algorithms, known as ciphers. Suitably scrambled text is known as cipher text while the original is, not surprising ly, plain text. Readability is neither a necessary nor sufficient condition for something to be plain text. The original might well not make any obvious sense when read, as would be the case, for example, if something already encrypted were being further encrypted. It’s also quite possible to construct a mechanism whose output is readable text but which actually bears no relationship to the unencrypted original. A key is used in conjunction with a cipher to encrypt or decrypt text. The key might appear meaningful, as would be the case with a character string used as a password, but this transformation is irrelevant, the functionality of a key lies in its being a string of bits determining the mapping of the plain text to the cipher text. 1. 1 Why we need cryptography? Protecting access to information for reasons of security is still a major reason for using cryptography. However, it’s also increasingly used for identification of individuals, for authentication and for non -repudiation. This is particularly important with the growth of the Internet, global trading and other activities[12]. The identity of e -mail and Web users is trivially easy to conceal or to forge, and secure authentication can give those interacting remotely confidence that they’re dealing with the right person and that a message hasn’t been forged or changed. In commercial situations, non-repudiation [12] is an important concept ensuring that if, say, a contract has been agreed upon one party can’t then renege by claiming that they didn’t actually agree or did so at some different time when, perhaps, a price was higher or lower. Digital signatures and digital timestamps are used in such situations, often in conjunction with other mechanisms such as message digests and digital certificates. 95 Subasree Sakthivel ? Design of a New Security Protocol IJRRAS 2 (2) ? February 2010 The range of uses for cryptography and related techniques is considerable and growing steadily. Passwords are common but the protection they offer is often illusory, perhaps because security policies within many organizations aren’t well thought out and their use causes more problems and inconvenience than seems worth it[14,15]. In many cases where passwords are used, for example in protecting word processed documents, the ciphers used are extremely lightweight and can be attacked without difficulty using one of a range of freely available cracking programs. 2. TYPES OF CRYPTOGRAPHIC ALGORITHMS 2. 1. Elliptic Curve Encryption When using elliptic curves in cryptography[11], we use various properties of the points on the curve , and functions on them as well. Thus, one common task to complete when using elliptic curves as an encryption tool is to find a way to turn information m into a point P on a curve E. We assume the information m is already written as a number. There are many ways to do this, as simple as setting the letters a = 0, b = 1, c = 2, . . . or there are other methods, such as ASCII, which accomplish the same task. Now, if we have E : y2 = x3 + Ax + B (mod p), a curve in Weierstrass form, we want to let m = x. But, this will only work if m3 + Am + B is a square modulo p. Since only half of the numbers modulo p are squares, we only have about a 50% chance of this occurring. Thus, we will try to embed the information m into a value that is a square. Pick some K such that 1/2K is an acceptable failure rate for embedding the information into a point on the curve. Also, make sure that (m + 1)K ; p. Let xj = mK + j for j = 0, 1, 2, . . . ,K ? 1 Compute x 3j + Axj + B. Calculate its square root yj (mod p), if possible. If there is a square root, we let our point on E representing m be P m = (xj , yj) If there is no square root, try the next value of j[4,5]. So, for each value of j we have a probability of about 1/2 that xj is a square modulo p. Thus, the probability that no xj is a square is about 1/2K, which was the acceptable failure rate[6]. In most common applications, there are many real-life problems that may occur to damage an attempt at sending a message, like computer or electricity failure. Since people accept a certain 16 amount of failure due to uncontrollable phenomenon, it makes sense that they could agree on an acceptable rate of failure for a controllable feature of the process. Though we will not use this specific process in our algorithms[10]. 2. 2. Dual RSA In practice, the RSA decryption computations are performed in p and q and then combined via the Chinese Remainder Theorem (CRT) to obtain the desired solution in ? N, instead of directly computing the exponentiation in ? N. This decreases the computational costs of decryption In two ways. First, computations in ? p and ? q are more efficient than the same computations in ? N since the elements are much smaller. Second, from Lagrange? s Theorem, we can replace the private exponent d with dp = d mod (p – 1) for the computation in ? p and with dq = d mod (q – 1) for the computation in ? p, which reduce the cost for each exponentiation when d is larger than the primes. It is common to refer to dp and dq as the CRT -exponents. The first method to use the CRT for decryption was proposed by Quisquater and Couvreur [7,8]. Since the method requires knowledge of p and q, the key generation algorithm needs to be modified to output the private key (d, p, q) instead of (d,N). Given the pri vate key (d, p,q) and a valid ciphertext C ? ? N, the CRTdecryption algorithm is as follows: 1) Compute Cp = Cdp mod p. 2) Compute Cq = Cdq mod q. 3) Compute M0 = (Cq – Cp) . p-1 mod q. 4) Compute the plaintext M = Cp + M0 . p. This version of CRT-decryption is simply Garner? s Algorithm for the Chinese Remainder Theorem applied to RSA. If the key generation algorithm is further modified to output the private key (dp, dq, p, q, p -1 mod q), the computational cost of CRT-decryption is dominated by the modular exponentiations in steps 1) and 2) of the algorithm. When the primes p and q are roughly the same size (i. e. , half the size of the modulus), the computational cost for decryption using CRT -decryption (without parallelism) is theoretically 1/4 the cost for decryption using the original method[7]. Using RSA-Small-e along with CRT-decryption allows for extremely fast encryption and decryption that is at most four times faster than standard RSA. 96 IJRRAS 2 (2) ? February 2010 Subasree Sakthivel ? Design of a New Security Protocol 2. 3 MD5 Algorithm MD5[2] consists of 64 of these operations, grouped in four rounds of 16 operations. F is a nonlinear function; one function is used in each round. Mi denotes a 32 -bit block of the message input, and Ki denotes a 32 -bit constant, different for each operation. s is a shift value, which also varies for each operation[1]. MD5 processes a variable length message into a fixed -length output of 128 bits. The input message is broken up into chunks of 512-bit blocks; the message is padded so that its length is divisible by 512. The padding works as follows: first a single bit, 1, is appended to the end of the message. This is followed by as many zeros as are required to bring the length of the message up to 64 bits less than a multiple of 512. The re maining bits are filled up with a 64-bit integer representing the length of the original message[9]. The main MD5 algorithm operates on a 128 -bit state, divided into four 32-bit words, denoted A, B, C and D. These are initialized to certain fixed constants. The main algorithm then operates on each 512 -bit message block in turn, each block modifying the state. The processing of a message block consists of four similar stages, termed rounds; each round is composed of 16 similar operations based on a non -linear function F, modular addition, and left rotation. Many message digest functions have been proposed and are in use today. Here are just a few like HMAC, MD2, MD4, MD5, SHA, SHA-1. Here, we concentrate on MD5, one of the widely used digest functions. 3. HYBRID SECURITY PROTOCOL ARCHITECTURE It is desired to communicate data with high security. At present, various types of cryptographic algorithms provide high security to information on controlled networks. These algorithms are required to provide data security and users authenticity. This new security protocol has been designed for better security using a combination of both symmetric and asymmetric cryptographic techniques.

The Asymmetric Key Cryptography technique, Dual RSA used for Authentication. 97 Subasree Sakthivel ? Design of a New Security Protocol IJRRAS 2 (2) ? February 2010 The new Security Protocol has been designed for better security. It is a combination of both the Symmetric and Asymmetric Cryptographic Techniques. It provides the Cryptographic Primitives such as Integrity, Confidentiality and Authentication. The given plain text can be encrypted with the help of Elliptic Curve Cryptography, ECC and the derived cipher text can be communicated to the destination through any secured channel. Simultaneously, the Hash value is calculated through MD5 for the same plain text, which already has been converted into the cipher text by ECC. This Hash value has been encrypted with Dual RSA and the encrypted message of this Hash value also sent to destination. The intruders may try to hack the original information from the encrypted messages. He may be trapped both the encrypted messages of plain text and the hash value and he will try to decrypt these messages to get original one. He might be get the hash value and it is impossible to extract the plain text from the cipher text, because, the hash value is encrypted with Dual RSA and the plain text is encrypted with ECC. Hence, the message can be communicated to the destination with highly secured manner. The new hash value is calculated with MD5 for the received originals messages and then it is compared with decrypted hash message for its integrity. By which, we can ensure that either the origi nal text being altered or not in the communication medium. This is the primitive feature of this hybrid protocol. 4. RESULTS AND CONCLUSION 4. 1 Comparison of RSA and Dual RSA 1) The Public Key Algorithms, RSA and Dual-RSA have been implemented in VC++ and we got the following results. As shown in the Figure 2, the original message for communication is stored in MyFile. txt and its size is 547 Bytes, which is shown in the report file. Figure 2 : Input File MyFile. txt Figure 3 shows that the project main menu, which consists of various features. They are i. RSA Encryption, ii. RSA Decryption, iii. Dual RSA Encryption, iv. Dual RSA Decryption, and v. Graph, which is used to compare the computational costs of both the RSA and Dual -RSA Figure 4 shows that RSA Encryption and Figure 5 shows that Dual RSA encryption. From the figure 6 it is clear that the RSA take one block at a time for encryption and decryption at a time. But the dual RSA take more time for encryption of two block at a time, but it take less time for decryption of two blocks. So, the RSA encryption and decryption time is greater than Dual RSA because Dual RSA perform the encryption and decryption operation for two blocks. 8 IJRRAS 2 (2) ?

February 2010 Subasree Sakthivel ? Design of a New Security Protocol Figure 7 : Computational costs of RSA vs Dual RSA Figure 6 shows that the Perfor mance Analysis of RSA vs Dual RSA. From this figure, it is clear that the total computation time for Encryption and Decryption of Dual -RSA is less than that of ordinary RSA. From the Figure 7, it is observed that the total computation time for Encrypt ion and Decryption of RSA is 4314ms as compared with the total computation time for Encryption and Decryption of Dual – RSA is 3203ms for the file size 547 Bytes. From the analysis it is clear that Dual RSA is better than RSA algorithm. So, for authentic ation we are going to use Dual RSA. Dual RSA take two block for encryption and decryption simultaneously. . 3 Results of Hybrid protocol Architecture Here, we are using three different mode of operation. The sender, Receiver and Intruder. We have t o select the mode and process the information. The following figure represent the three different mode. Figure 8 : Mode selection If the mode is the sender, then we have to provide the key val ue and messages in the specified location. Figure 9 : Sender Mode 101 Subasr ee Sakthivel ? Design of a New Security Protocol IJRRAS 2 (2) ? February 2010 Figure 10 shows that the Receiver received the sender message with the key. From the figure, it is noted that, the intruder also received the key and not the message. Because, the message is encrypted with ECC and key is encrypted by using Dual RSA. And also noted that, the intruder derived different key for decryption, which is equivalent to the original key. Even though the intruder got the key he cannot able to get the orig inal message because of Dual RSA. Because of Dual RSA we got two advantages one is the message cannot be decrypted and time required to perform the encryption and decryption operation less compare to RSA because Dual RSA perform encryption and decryption by two block at a time. The new Public Key Cryptographic algorithm, Dual – RSA has been developed for better performance in terms of computation costs and memory storage requirements. It is also called RSA -CRT, because it is used Chinese Remainder Theorem, CRT for its Decryption. From the output, it is noted that Dual -RSA improved the performance of RSA in terms of computation cost and memory storage requirements. It achieves parallelism. The CRT Decryption is achieved roughly ? times faster than original RSA. Figure 10 : Secured communication of Hybrid Protocol 102 IJRRAS 2 (2) ? February 2010 Subasree Sakthivel ?

Essay On The Stamp Act Example For Students

Essay On The Stamp Act The Stamp Act was passed by the British Parliament on March 22, 1765. The new tax was imposed on All-American colonists and required them to pay a tax on every piece of printed paper they used. Ships papers, legal documents, licenses, newspapers, other publications, and even playing cards were taxed. The money collected by the Stamp Act was to be used to help pay the costs of defending and protecting the American frontier near the Appalachian Mountains (10,000 troops were to be stationed on the American frontier for this purpose). The actual cost of the Stamp Act was relatively small. What made the law so offensive to the colonists was not so much its immediate cost but the standard it seemed to set. In the past, taxes and duties on colonial trade had always been viewed as measures to regulate commerce, not to raise money. The Stamp Act, however, was viewed as a direct attempt by England to raise money in the colonies without the approval of the colonial legislatures. If this new tax were allowed to pass without resistance, the colonists reasoned, the door would be open for far more troublesome taxation in the future. Few colonists believed that they could do anything more than grumble and buy the stamps until the Virginia House of Burgesses adopted Patrick Henrys Stamp Act resolves. These resolves declared that Americans possessed the same rights as the English, especially the right to be taxed only by their own representatives; that Virginians should pay no taxes except those voted by the Virginia House of Burgesses; and that anyone supporting the right of Parliament to tax Virginians should be considered an enemy of the colony. The House of Burgesses defeated the most extreme of Henrys resolutions, but four of the resolutions were adopted. Virginia Governor Fauquier did not approve of the resolutions, and he dissolved the House of Burgesses in response to their passage. Words/ Pages : 320 / 24

The negative impact of cigarette smoking free essay sample

Christy Turlington Burns once said, â€Å"It is better to not even try it than to endure the ramifications of either quitting smoking or dying. † This quote is relevant because when most teens try their first cigarette they do not think through the consequences of their actions. I believe tobacco use among teens in America is harmful and should be stopped. This is because of the risk of addiction, the health problems cigarette smoking causes and the possibility of premature death. According to The American Lung Association, one third of those who start smoking under the age of 18 become regular smokers. That accounts for 800,000 new smokers annually. Ninety percent of smokers began smoking before the age of 21. These facts show that how early you start really does have an influence on if you will be a lifetime smoker. Most adolescents that have smoked at least a hundred cigarettes report that they want to quit, but are not able to do so. We will write a custom essay sample on The negative impact of cigarette smoking or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page Regular adolescent smokers can have just as hard of a time quitting as would a long time smoker. According to the World Health Organization, around fifty percent of those who start smoking when they are younger end up smoking for fifteen to twenty years. This proves that you do not have to smoke for a long time to become addicted, and once you are addicted it is a struggle to quit. This evidence provided promotes how essential it is for adolescents to avoid addiction. Growing up is already challenging enough without having to struggle with an unhealthy addiction. As shown by The American Lung Association, cigarette smoking causes severe health problems, especially in younger individuals. They have proven that smoking causes an increased severity in respiratory problems, like increased coughing and phlegm production. Smoking also causes a decrease in physical fitness, and a potential slowed rate of lung development. Both of these factors can decrease a teens overall quality of life and prevent them from living a normal healthy life. Having bad health can also set adolescents up for further health problems in the future. A decreased quality of life is not the only thing smokers need to worry about. Smokers have the risk of a premature death as well. The diseases caused by smoking kill about 440,000 Americans per year according to The American Lung Association. If something is not done, it is estimated that 6. 4 million children will die before their time due to illness caused by smoking tobacco. It is vital that adolescent tobacco smoking must be stopped for the health of this generation, and those to come. As of now most people do not take the risk of death caused by smoking as a serious threat. Taking this issue seriously will put us on a healthier path. In short, tobacco use is harmful among teens and should be stopped because of the risk of addiction, the health problems cigarette smoking causes and the possibility of premature death. I believe banning the glorification and glamorization of smoking tobacco products in advertisements, as well as making the risks more apparent would lessen the use of tobacco in adolescents significantly. As Christy Turlington Burns said, â€Å"It is better to not even try it than to endure the ramifications of either quitting smoking or dying. †

buy custom Attitude towards Exercise essay

buy custom Attitude towards Exercise essay Attitude can influence someone positively or negatively towards something. If you have a positive attitude towards something, you will always support it and you will be ready to perform anything associated with it because it lies under your area of interest. Negative attitude on the other hand, will make you ignore anything that you have a negative altitude towards despite the benefits you might gain from it. From the above explanation, we can see that there are two types of altitudes towards something. These two attitudes can be simply classified as positive and negative attitudes. The attitude you have towards exercise can be beneficial to you or ruin your life. Having a positive attitude towards exercising is very important because the benefits of exercising outdo the shortcoming of it. People who have a negative attitude towards exercises usually have health problems such as obesity, they are prone to heart attacks and have difficulties in their diet taking. There are numerous benefits associated with having a positive attitude towards exercising. Physical exercises are very important for maintaining physical fitness and overall health and wellness. Exercises are very crucial since they help to improve your body energy. Combination of exercise and nutritiondevelop a hormonal environment fit to fat loss thus, increased energy. Physical exercises also increase self-esteem because they help someone to gain control of their body size and weight and this will automatically increase their self-esteem. Physical exercises are also attributed to increased mental focus as they help to keep the brain sharp into old age. Another key benefit of exercising is that it helps to reduce the risk of heart attack. Physical exercises lower cholesterol and blood pressure and this diminishes the chances of having a heart attack. Production of endorphin increases through exercise and this improves mood and suppresses depression. Physical exercises are also known to reduce stress level. Taking and exercise right after work is a perfect natural therapy that help you to change your mood, it will also help you to sleep better. These are just a few examples of the benefits of taking physical exercises. Those with positive attitude towards exercises take physical exercises regularly and thus keep their body fit and free from unnecessary health problems such as obesity. Some people have a negative attitude towards exercise though this cannot be considered as their preference to do so. Some of them have physical disabilities thus they hate pphysical exercises with all might. There are others with physical disability if encouraged to have a positive attitude towards exercises can concur their disabilities and be able to life a normal life. This can be portrayed by people with weak limps, if encouraged to take physical exercises regularly their limps can gain strength and they will be able to live a normal life. Obese people should also be encouraged to take exercises so that they can reduce the chances of developing other health problems. Negative attitude towards exercises should be discouraged because it is clear that physical exercises are beneficial to our health. In conclusion, attitude can be said as socially created and modified using direct contact with the variable you are interested in. this suggests that those people with a negative attitude towards physical exercises, their notions and feelings towards exercises can be easily be altered. People should be encouraged take physical exercises regularly so that they can make their bodies physically fit and escape some diseases. To build a positive attitude towards exercises we should start encouraging people take physical exercises when they are young so that they can develop this culture and erode the negative attitude at an early stage.

Challenges Facing Airport Management

Challenges Facing Airport Management Air travel remains a large and growing industry. It facilitates economic growth, world trade, international investment and tourism and is therefore central to the globalization taking place in many other industries which results in various challenges the airport authorities are facing in the 21st century. In the past 10 years, air travel has grown by 7% per year. Travel for both business and leisure purposes grew strongly worldwide. Scheduled airlines carried 1.5 billion passengers last year. In the leisure market, the availability of large aircraft such as the AIBUS 380 made it convenient and affordable for people to travel further to new and exotic destinations. As the economies of developing countries grow, their own citizens are already becoming the new international tourists of the future. There are various Challenges facing Airport management in the 21st Century. Different airports have different problems but one thing is for sure that some of the issues like the core issues remain the same. These are basically security of the airport especially after the 9/11 attack on US soils and the ic184 hijack in Katmandu. The rise in people travelling through the air travel has also lead to increase the facilities at the airport and new planes like A380 aircraft which results the airport to increase its infracture of the airport right from the runway to the passengers lounges to the aerobridges. As more and more companies are buying A380 there would be large requirement for the airports to upgrade their facilities according to the requirements. Bigger the infracture, more the passengers traveling bigger the facelift of the airport required and more up gradation of the facilities like parking of the passenger cars. Let us start of with the various security issues the airports are facing around the world. Large numbers of people pass through airports. This presents potential targets for terrorism and other forms of crime due to the number of people located in a small area. Similarly, the high concentration of people on large airlines, the potential high death rate with attacks on aircraft, and the ability to use a hijacked airplane as a lethal weapon may provide an alluring target for terrorism. Airport security attempts to prevent would-be attackers from bringing weapons or bombs into the airport. If they can succeed in this, then the chances of these devices getting on to aircraft are greatly reduced. As such, airport security serves several purposes: To protect the airport from attacks and crime and to protect the aircraft from attack, and to reassure the travelling public that they are safe. Process and equipment Some incidents have been the result of travelers being permitted to carry either weapons or items that could be used as weapons on board aircraft so that they could hijack the plane. Travelers are screened by metal detectors. Explosion detection machines used include x-ray machines. Explosive detection machines can also be used for both carry on and checked baggage. These detect volatile compounds given off from explosives. A recent development is the controversial use of full body scanners to detect hidden weapons and explosives on passengers. These devices require that the passenger stand close to a flat panel and produce a high resolution image. There are misunderstandings about how x-ray backscatter personnel scanners function, but they do use ionizing radiation and the x-rays emitted from them penetrate skin as well as clothing. While the risk of cancer from a single backscatter check is probably low, the cumulative risk of repeated exposure to radiation is a threat to public he alth, especially for people working in the airline industry and frequent travelers. A technology released in Israel in early 2008 allows passengers to pass through metal detectors without removing their shoes a process required as walk-though gate detectors are not reliable in detecting metal in shoes or on the lower body extremities. Alternately, the passengers step fully shod onto a device which scans in under 1.2 seconds for objects as small as a razor blade. Generally people are screened through airport security into areas where the exit gates to the aircraft are located. These areas are often called secure, sterile and airside. Passengers are discharged from airliners into the sterile area so that they usually will not have to be re-screened if disembarking from a domestic flight; however they are still subject to search at any time. Airport food outlets have started using plastic glasses and utensils as opposed to glasses made out of glass and utensils made out of metal to reduce the usefulness of such items as weapons. In the United States non-passengers were once allowed on the concourses to meet arriving friends or relatives at their gates, but this is greatly restricted now in the United States. Non-passengers must obtain a gate pass to enter the secure area of the airport. The most common reasons that a non-passenger may obtain a gate pass is to assist children and the elderly as well as for attending business meetings that take place in the secure area of the airport. In the United States, at least 24 hours notice is generally required for those planning to attend a business meeting inside the secure area of the airport. Other countries, such as Australia do not yet restrict non-travelers from accessing the airside area, however non-travelers are typically subject to the same security scans as travelers. Sensitive areas in airports, including airport ramps and operational spaces, are restricted from the general public. Called a SIDA Security Identification Display Area, these spaces require special qualifications to enter. In some countries, specially trained individuals may engage passengers in a conversation to detect threats rather than solely relying on equipment to find threats. In the United States the TSA has run several dummy tests in several major airports to measure the success of catching people with bombs. In 2002, the TSA reported that roughly 60% of fake bombs or component parts to bombs were missed by covert screeners. In 2007, that percentage rose to 75%, although this increase alone is misleading. The tests are done by using undercover agents to carry fake bombs/parts in their carryon luggage and counting how many are successful with getting through security checkpoints. The TSA runs covert tests every day and when a screener misses an undercover agent carrying dangerous items, they are immediately sent to remedial training. Throughout the world, there have been a few dozen airports that have instituted a version of a trusted traveler program. Proponents argue that security screening can be made more efficient by detecting the people that are threats, and then searching them. They argue that searching trusted, verified individuals should not take the amount of time it does. Critics argue that such programs decrease security by providing an easier path to carry contraband through. Another critical security measure utilized by several regional and international airports is the use of fiber optic perimeter intrusion detection systems. These security systems allow airport security to locate and detect any intrusion on the airport perimeter, ensuring real-time, immediate intrusion notification that allows security personnel to assess the threat and track movement and engage necceassary security procedures. This has notably been utilized at Dulles International Airport and US Military JFPASS. Developing countries like india which have a high rate of terrorists attack have a very extensive way of dealing with security of the airport. : Security at the Indira Gandhi International Airport has been revamped with the integration of anti-sabotage detection and intrusion systems of both international and domestic terminals along with the anti-terror commando squad. After the commissioning of the world class T3 terminal on July 3 by Prime Minister Manmohan Singh, the security of the airport will be brought under a unified monitoring system known as the Security Operations Control Centre (SOCC). Entry, frisking, scanning, baggage checking, anti-sabotage and quick reaction deployment will be brought under a single umbrella. The new control centre, aided by improved scanning and surveillance software and hardware, will be monitored by the Central Industrial Security Force (CISF) which is the agency protecting the sensitive airport and its periphery. The ambitious and much-awaited Perimeter Intrusion Detection System (PIDS) to secure 37 kms of the airport periphery from illegal intruders will also be connected to the SOCC, a senior airport security officer said. With the security management of both the domestic and international terminals coming under an umbrella, the facility would enable a better coordination for security of passengers and other airport staff, the officer said. A special squad of the National Security Guard (NSG) black cat commandos, stationed at a newly-built airbase next to the airport, will also be associated to the new control centre. A host of new services like the Delhi Metros airport link will connect to the airport and hence the multi-tasking of security drills will grow manifold. The integrated security terminal will help in achieving the daunting task, the officer said. The control centre will also monitor the almost 3,000 CCTV cameras and 352 screening machines spread across the sprawling airport premises. The new terminal would be able to handle as many as 34 million passengers per annum against the present 26 million, as it would have eight levels with a built-up area of 5.5 million sq ft. It would have a common check-in concourse with 168 counters and 24 mobile ones apart from the most modern five level in-line baggage system for faster processing. Around 5000 CISF personnel will be deputed at the IGI airport in view of the new T3 terminal and the forthcoming Commonwealth Games. Large Size of A380 Brings Large Challenges The A380 is expected to impact the industry in two ways. On the one hand, the immense capacity of the aircraft opens up opportunities to increase passenger flow through airports without increasing the number of aircrafts. This is likely to enhance efficiency of airports as well as minimise unit costs, an important advantage considering the limited number of slots at airports. The flip side of this is that airports will need to restructure their facilities and invest heavily in infrastructure to enable future operations of the A380. However, it appears that many airports are more than prepared for the projected expenditure since they expect to gain multiple advantages from the future operations of the jet. The sheer size of the Airbus A380 brings with it immense potential but equally big challenges. Currently, the greatest challenge facing the industry is the need to adjust their facilities to accommodate an airplane code F, when most of the major international airports have the required infrastructure for aircraft code E. Although Airbus initially developed the A380 to operate on runways of code E standard, subsequent rulings by the International Civil Aviation Organization (ICAO) stated that it belonged to code F category and called for airports to expand their facilities to accommodate it. Hence, airports are spending millions of dollars for investment in this infrastructure, says the analyst. However, regulators and the aviation industry representatives have now struck a compromise that allows airports to be certified for A380 operations while minimising capital expenditure and operational disruption. Overall, airports are divided in their attitude towards the A380 and the modifications it demands depending on their current position in international air traffic. While some airports feel they have no choice but to embrace the changes, some others are deciding on the feasibility of preparing their facilities and handling the jet after carrying out a cost-benefit analysis. The remaining airports fall into the category of those that voluntarily make the required adjustments in an attempt to increase the airportà ¢Ãƒ ¢Ã¢â‚¬Å¡Ã‚ ¬Ãƒ ¢Ã¢â‚¬Å¾Ã‚ ¢s appeal in the international arena and thereby, attract new airlines operating the A380. CHANGI MODIFICATIONS CAAS is spending S$60m on modification works to get Changi Airports Terminal 1 and Terminal 2 ready for A380 operations. Besides modifying gate F31, CAAS has completed the expansion of one more A380-compatible gate holdroom in Terminal 2, gate E5. This includes the installation of an additional gangway and a third PLB. Nine other existing gate holdrooms in Terminal 1 and Terminal 2 are being similarly modified. The future Terminal 3 will have another eight A380-compatible gates, bringing the total number of A380-compatible gates at the airport to 19. Each of the 19 gates will have three PLBs. In addition, three out of four baggage claim carousels serving A380 flights in Terminal 2 have been extended to accommodate more luggage, while two A380-ready baggage claim belts in Terminal 1 will be ready in 2006. Other modification works will include the widening of runway shoulders as well as runway-taxiway and taxiway-taxiway intersections. Besides making modifications to existing infrastructure, CAAS has constructed two new freighter aircraft stands and two remote aircraft parking stands for A380 flights. Shields have also been installed along each side of a taxiway bridge to contain the effect of the A380 jet blast. Similar shields are being installed at another taxiway bridge at Changi Airport. In preparation for the A380 operations at Singapore Changi Airport in 2006, CAAS has been carrying out modification work to the existing airport infrastructure as well as incorporating A380 requirements into the design and construction of Terminal 3. As the A380 aircraft is wider and heavier than the Boeing 747-400, Changi Airports airfield must be modified to the design requirements of the ICAO for Code F aircraft. At Changi Airport, the existing runway length of 4000m and width of 60m meet the requirements for A380 operations. The existing separation distances between runways, taxiways and nearest obstacles also meet the international norms specified for A380 operations. However, the existing runway shoulders have been widened by 4.5m on each side to allow the A380 aircraft to operate safely. The aircraft pavements at runway-taxiway and taxiway-taxiway intersections are being widened to allow pilots to manoeuvre the giant A380 aircraft safely at the turns. CAAS is spending S$60m on modification works to get Changi Airports Terminal 1 and Terminal 2 ready for A380 operations. Shields have been installed along each side of a taxiway bridge to contain the effect of the A380 jet blast. Similar shields are being installed at another taxiway bridge at Changi Airport. To facilitate passenger movements from the terminal buildings to the aerobridges, existing fixed gangways (which link the gate holdroom to the aerobridge) are being modified at the designated gates for A380 operations. Each of these gates will be installed with an additional fixed gangway and a third aerobridge. They will also be enlarged to serve the increased number of passengers that the A380 will carry. Two of the existing gates, F31 and E5, in Terminal 2 are now A380-compatible. Similar works have been scheduled to modify five gates in Terminal 1 and four other gates in Terminal 2. Terminal 3 will have eight gates that can serve A380 flight operations when the terminal opens. In all, Changi Airport will have 19 enlarged gate holdrooms to accommodate A380 flights. To accommodate the larger volume of arrival baggage from A380 flights, the presentation frontage of existing baggage belt carousels in Terminal 1 and Terminal 2 has been extended to about 90m. Extensions to three of the four belt carousels in Terminal 2 serving A380 flights have been completed and in Terminal 1 two belts were lengthened in early 2006. Four belts in the upcoming Terminal 3 will be custom-made to serve A380 flights. Two new A380-compatible freighter aircraft stands and two new A380-compatible remote aircraft parking stands have been constructed. Some of the key features of the new terminal are: -Sixth largest in the world after those at Dubai, Beijing, Singapore, Bangkok and Mexico City -One pier each for international and domestic operations spanning 1.2 km from one end to other -A city within, with a super-structure spread over 5.4 million sq ft -78 aero-bridges, against less than 10 at the current international terminal -63 elevators, 35 escalators and 92 automatic walkways -168 check-in counters and 95 immigration desks -One pier each for international and domestic operations spanning 1.2 km from one end to other -Over 20,000 sq meters of retail area, including a large food court -Capacity to handle 12,800 bags per hour, with 6.4 km of conveyor belts -Multi-layer parking facility that can accommodate 4,300 cars -Exotic plants, material imported from Thailand, Mexico, Bahrain. The analysts were looking at GMRs work on Terminal 3 aka T3 at Delhi Airport a symbol of the so-called Modern and Bold India, considering it is among the worlds largest airport terminals and constitutes the largest infrastructure asset in India today. While the language may be a bit technical, it does give some insight into two important subjects: a) how companies are assessed; and, more importantly from a big picture angle, b) the dynamics of Indian infrastructure growth. For more on this crucial subject, see tomorrows Featured Analysis, which compares the dynamics of Chinese and Indian urbanization for the next decade and a half. Check notepad. 1.3.1 London Heathrow London Heathrow will be used as the baseline airport in this study for several reasons: _ Large number of expected A380 operations. _ Extensive operational data readily available. _ Arrivals and departures are always segregated. _ Operation at close to runway capacity throughout the day. Under In November 2009 London Heathrow accommodated 4 daily Heathrow operations (2 ights to Singapore, one to Dubai and one to Sydney), this _gure will rise substantially as Airbus delivers more aircraft across the world given that Heathrow is a major international hub. Heathrow is also likely be the base of operations for the 18 A380s to be operated by British Airways and Virgin Atlantic. In addition to the volume volume of future A380 operations Heathrow is a useful baseline airport given the wealth of data available about operations at the airport as well as the simple operational modes of its runways. Heathrow always operates one runway for arrivals and one runway for departures (to minimize the noise impact on communities under the approach path [6]). Heathrow also operates close to its runway capacity for most of the day due to slot controls at the airport. These factors 4 of 15 Airport Systems: Term Project Alexander Donaldson together mean that a simple runway capacity model described in Section 2.1 should yield an accurate estimate of arrival capacity at Heathrow. 1.3.2 New York JFK An American airport was included in the study in order to examine the e_ects of the more stringent separation requirements impose by the FAA as well as the e_ect of the lower aircraft size seen on average in the U.S. New York JFK (JFK) is likely to be one of the top U.S airports in terms of A380 operations1. JFK is also an interesting contrast to London Heathrow because its runways are frequently operated in a mixed-mode con_guration, with arrivals and departures sharing the same runway. Figure 3: New York JFK Airport Layout[7] 1.3.3 Dubai International Dubai International Airport (DXB) was chosen as the third airport in this study due to the potentially unmatched future level of A380 operations asa result of Emirates Airlines 1Los Angeles International (LAX) my handle more A380s however it was not used in this study due to the complications imposed on A380 operations by its closely spaced parallel runways and the uncertainty surrounding the resolution of these issues. 5 of 15 Airport Systems: Term Project Alexander Donaldson (based at DXB) large order for 58 of the type (Figure 1). The airport also adds a third distinct separation standard by applying the ICAO recommendations without modi_cation. Like JFK, Dubai International has a pair of parallel runways assumed to be operating independently with mixed arrivals and departures for the purposes of this study.

Homosexuality And Its Effects On Humans Essay - 2380 Words

Over the years, substantial amounts of research has been conducted in finding the causes of homosexuality in humans. Throughout which, researchers aimed to find if sexual orientation was either controllable or uncontrollable. Many argue that it is in fact controllable and thus dependent on either being a learned trait, an individual’s choice or due to environmental conditions in which one is raised. On the other hand, others find it to be uncontrollable or innate and thus due to biological or genetic factors (Haider-Markel Joslyn, 2008). In the following essay I aim to critically evaluate the claim of whether homosexuality is in fact innate by examining the current research and data of both sides of the argument. In an attempt to understand the cause of homosexuality, researchers began by examining the anatomy of the brain, particularly in primate species. Slimp, Hart Goy (1976) established the role of the medial preoptic – anterior hypothalamus (MP-AH) by making radiofrequency lesions bilaterally on adult male rhesus monkeys. By doing so they observed that the males still possessed a sex drive (masturbation and yawning – a sexually dimorphic behaviour), but would refuse to have sex with females, possibly implying a change in sexual orientation. This led them to conclude that the MP-AH area is more specifically involved with sexual behaviour that is directed towards a partner. Further investigating of the hypothalamic region was conducted by Allen, Hines, Shryne Show MoreRelatedDoes Homosexuality Change the Brain or the Brain Results in Homosexuality?1039 Words   |  5 Pages Homosexuality is a product of biology because according to research, the hormones of the females are stronger. Dr. Hamer states that sexual orientation, male homosexuality is genetically influenced. This is passed down through their mothers to the hormone of their offspring.
