Biometric Systems Essay, Research Paper Biometric Systems As defined in Computer Security Basics by O # 8217 ; Reilly A ; Associates, Inc. Biometricss is the usage of a individuals alone physiological, behavioural, and morphological features to supply positive personal designation. Biometric systems that are presently avaiable today examine fingerprints, handprints, and retina forms. Systems that are close to biometries but are non classified as such are behavioural systems such as voice, signature and key stroke systems. They test forms of behaviour non parts of the organic structure. It seems that in the universe of biometries that the more effectual the device, the less willing people will be to accept it. Retina pattern devices are the most dependable but most people hate the thought of a optical maser shot into their oculus. Yet something such as supervising keystroke spiels people don # 8217 ; t head, but it # 8217 ; s non about as effectual. Biometric confirmation is forecast to be a multibillion dollar market in this decennary. There is no uncertainty that fiscal recognition and debit cards are traveling to be the biggest portion of the biometric market. There are besides many important niche markets which are turning quickly. For illustration, biometric designation cards are being used at a university in Georgia to let pupils to acquire their repasts, and in a Maryland twenty-four hours attention centre to guarantee that the right individual picks up the right kid. In Los Angeles, they are utilizing fingerprints to halt public assistance fraud. A neodymium they’re besides being used by frequent concern travelers for rapid theodolite through in-migration and imposts in Holland, and now at JFK and Newark airdromes in the United States. It could besides be used to merely forestall one employee from # 8220 ; pluging in # 8221 ; for some one else, or to forestall person from opening up an history at a bank utilizing a false name. Then there is besides the security entree market, entree to computing machine databases, to premises and a assortment of other countries. The Sentry plan made by Fingerprint Technologies uses several devices at one time. The system first prompts for a user name and watchword. Then they must hold their fingerprint scan lucifer what is on record. They can besides utilize a picture camera for existent clip picture to capture exposure which can be incorporated into the information base. The clip to scan and derive entryway to the edifice return from 6 to 10 seconds depending on what other information the operator wishes the user to come in. The system besides keeps on record three of the persons finger forms incase one of the others is injured. Biometricss is still comparatively new to most people and will stay expensive to buy good equipment until it becomes more popular and the engineering gets better. And as people become more cognizant of how the systems work they will go more accepting of the more unafraid systems and non shy away from them every bit much.

One of the challenges is to select expatriates and their ability to manage with integrity. Companies have to monitor the social performance of its expatriate managers to ensure that as managers become familiar with the cultural aspects of the country. Here we will take up an organization which is truly of global nature to discuss various HR issues. Ingvar Kamprad opened his furniture retailer IKEA in 1950; it now employs around 70, no. people, operates in thirty countries and generates a turnover of 11 billion Euros. Since its inception in 1950's IKEA has had to deal with the problem of maintaining its unique 'Swedishness' as a competitive advantage and at the same time having to adopt this to the different national cultures in which it has been working. IKEA has over the last 25 years become a global player this is unusual in furniture industry, which is often remains national in character. It has established itself all over Europe including the south and East and in North America. Its biggest single markets are Germany, Sweden and France. It has recently taken over Habitat, its main rival in UK and France. It has adopted the culture and philosophy of consensus decision making. Human resource management practices have reflected the strong Swedish approach with a belief that people like to participate in decision making, like to be respected and take on responsibility. But the company is working in multinational brand its human resource management policies are bound to face some problems. National culture is one such area. A national culture involves a complete system of customs, habitat rules values and belief shared by an overwhelming majority of the countries in habitants. People from different cultures view aspects of life in co ntrasting ways. Cultures even view time differently; some emphasize punctuality while others reflect little sense of urgency. There is considerable literature in cross cultural management. Hofstede is one of the most known theorists in this field. Hofstede's 1981 study, cultures consequences of culture dimensions constructed cultural dimensions; so that culture could be measured along four scales i.e. power distance, uncertainty avoidance, individualism/collectivism and masculinity/femininity. Hofstede's after work (2001) includes a fifth dimension, long-term/short-term orientation. Trompenaars and Hampden-turner's (1997) model examine culture with three main domains: relationships and rules, attitudes to time and attitudes to environment. Apart from these theories we have to remember that cultures are not static and change overtime. As countries become more affluent their population becomes more individualistic (Triandis, 2004). International assignees have to learn to work in thre e different cultures- national organizational and professional and these cultures shift in over time. Different cultures hold different conceptions and assumptions about organizations and their management. Hofstede's dimensions of culture can be applied to business practices in different countries to gain some

Technologies for Killing People Essay Example | Topics and Well Written Essays - 2000 words

Technologies for Killing People - Essay Example Gas weapons, small arms, large guns and weapons of mass destruction are reported to be used more these days. The most lethal and most enigmatic use of technology or biological weaponries is considered to be the use of Zyklon B and other gases in concentration camps of Auschwitz by Germans during the World War II. Zyklon B is actually the German name for a gas called Cyclone B which is a cyanide based pesticide. The Nazi Germans used this gas to kill Jews in the concentration camps of Auschwitz during the holocaust which took 6 million lives of German, Polish and Russian Jews. The chambers in which the Jews were held to be killed by the insertion of Zyklon gas were of two, i.e. the first type of chambers was used for delousing clothes and the other one was utilized for killing Jews on a large scale. The later chambers were also called extermination chambers. Zyklon B is prepared from the extraction of hydrogen cyanide which is also called prussic acid. Before the usage of Zyklon B by Germans, it was used for fumigation purposes in farms where vegetables, fruits and grains are cultivated. Zyklon B is an effective pesticide, which is considered to be carry9ing clouds of Hydrocyanic Acid within each granule1. Germans used Zyklon B in a pallet or diskette form which was thrown into the sealed chambers where hundreds of human beings were held to kill at a time. The pallets were inserted into the room from small windows after which the windows were sealed and a team of physicians used to wait outside the chambers for 20 minutes, in order to ensure that every living organism inside the room is dead. While describing the gassing of Jews from Zyklon B, Hans Stark, the then leader of Western Infantry of German Army, described that when Zyklon B granules were poured into a gas chamber where around 225 Jews were held, the prisoners first started to cry out loud from the fear of death. After 20 to 25 minutes, the voices inside the gas chamber were vanished; this was a hint t hat every living organism inside the chamber is dead2. Beside Zyklon B, other gases were also utilized by Germans to kill their enemies. When the Great War broke up, poison gases were use as an alternative to machine guns and tanks. It is estimated that the largest number of fatalities took place during the World War II were caused by poison gases such as Phosgene and Chlorine. The first world in particular, has been popular as â€Å"The Chemists’ War†. Germans were of the view that gases and chemicals are a better weapon as compare to guns, crafts and tanks, as they kill those enemies as well who are hiding in corners and hinges. Although the process of killing a human being with the help of gases was slow but Germans were persistent that these gases will give more pain to human and will cause psychological defeat to the enemies’ camps. Since the use of Zyklon B, there are numerous chemical weaponries that were developed by human beings to kill other humans. An thrax is another deadly virus or bacteria, which have claimed thousands of lives not only in the modern era and its roots go deep into the usage of the bacteria during the World War II. Anthrax is not only used to kill human beings but it is also considered deadly for the animals. Anthrax

Introduction to Networking - Essay Example The part of the controller stack is usually implemented in a low cost device, which contains a microprocessor and a Bluetooth radio. The host stack is implemented as an installable package or an operating system. In integrated devices like Bluetooth headsets, the controller and host stack are run on the same microprocessor in order to reduce production costs. L2CAP is used in the Bluetooth protocol stack to pass packets to Host Controller Interface (HCI) or to the link manager. Communication between computers in a fibre channel network utilizes various elements of the fibre channel principles. Fibre channel communication is usually done in units of four 10-bit codes referred to as transmission word. The transmission words enhance passage of information between the systems. In transferring information, it is indispensable for fibre channel communication to comprise some meta-data. This facilitates setting up of links and sequence management. The fibre channel protocol usually transmits data in frames. In addition, the protocol has non-data frames, which are used for messaging and setup purposes (Matthews, 2005). File transfer protocol is a network protocol used in transferring files between two hosts over a TCP based network like the internet (Liang, 2011). It is mostly used in uploading web pages from a private development system to a public web-hosting server. It is built using client-server architecture and uses different control and data connections in the client and server. This protocol describes an internet standard for email transmission across the internet protocol networks. This protocol works best when the receiving and sending machines are connected to a network all the time. This protocol comprises three command sequences, which include mail command, RCPT and data commands. The mail command establishes the return address while RCPT command establishes the recipient of the message. On the other hand,

Users select their destinations GROUP ASSIGNMENT PART Study the following case study and answer all the tasks listed. An automated ticket-issuing system sells rail tickets as you find in London underground and over ground railway stations. Users select their destinations and can be pay cash the exact amount or input a credit card and a personal identification number (PIN). The rail ticket is issued and their credit card account charged if the ticket was bought using a credit card. When the user presses the start button, a menu display of potential destinations is activated, along with a message to the user to select a destination. Once a destination has been selected, users are requested to pay cash or input their credit card. In the last case, its validity is checked and the user is then requested to input a personal identifier. When the credit transaction has been validated, the ticket is issued. ambiguities or omissions in the above scenario An automatic ticket issuing system sells rail tickets. Users select their destination, and input a credit card and a personal identification number. The rail ticket is issued and their credit card account charged with its cost. When the user presses the start button, a menu display of potential destinations is activated along with a message to the user to select a destination. Once a destination has been selected, users are requested to input their credit card. Its validity is checked and the user is then requested to input a personal identifier. When the credit transaction has been validated, the ticket is issued. Ambiguities and omissions include: Can a customer buy several tickets for the same destination together or must they be bought one at a time? Can customers cancel a request if a mistake has been made? How should the system respond if an invalid card is input? What happens if customers try to put their card in before selecting a destination (as they would in ATM machines)? Must the user press the start button again if they wish to buy another ticket to a different destination? Should the system only sell tickets between the station where the machine is situated and direct connections or should it include all possible destinations? What type of input device (touch screen vs. keyboard)? Ticket prices Room on train (assumes tickets have times on them) Train departure and arrival times. Do customers buy tickets for a specific train? Or for any trip along the route? (If the latter, then no way to tell if all the seats on a train are sold out, nor can you do seat assignments.)

If unsuccessful again, prompt that the transaction has failed, and return to start state. Requires Destination, credit card number and PIN Pre-condition None Post-condition None Side effects Charge to the customers credit account user requirements definitions The user requirements for a system should describe the functional and nonfunctional requirements so that they are understandable by system users without any technical knowledge. When we write the user requirement we should not write with technical forms, table or diagrams. We should write in simple language with simple table, forms and diagrams. The actors in the system are the passenger, the counter clerk and the reservation system consisting of form processing, reservation, fare computation, ticket processing, ticket printing, collection of fare amount and posting as sub-systems. The passenger is a passive user-actor who initiates the process and obtains the ticket(s), a goal of measurable value. The counter clerk is an active user-actor, who triggers the system and has the role of issuing the tickets with the responsibility of collecting the correct fare amount from the passenger, which is a measurable value. Predesigned and deployed ticket reservation system at the back end is a system actor-user to ensure that ticket processing is done correctly and different system statuses are updated on issuing of tickets. This actor has an active role and responsibility at the back end. system requirements specifications System requirements Specifications are specified using the standard way of these forms. Function: Issuing Ticket Description: Issuing the ticket when the user select their desired tickets and make the correct payment. Inputs: Destination, child or Adult ,Pay by card or cash Output: Their desired ticket to be issued with their payment receipt Requires : Money Pre- Condition: Ticket will be validate between the user current place and the selected destination, Otherwise user will have to pay the penalty fare. a sequence diagram Scenario 1 This diagram shows about the user wants their ticket from the machine. It shows the interaction between user and ticket machine where user puts the requirement to the machine and the machine gives options back to the user. Scenario 2 This diagram shows the user chose the station and the machine give option back to user needs to choose from following option for e.g return ticket which class user wants to travel. After selecting options the user needs to pay for payment machine give option for eg cash or card. If the user choose card the ticket machine need to validate from card user. Scenario 3 This diagram represents a sequence activity when user buy a ticket using credit or debit card. When the user insert the card. The card is validated with the card issuer the validation of the card is returned to machine which then displays the result to the user. If the card is valid then the user need to enter the pin. The validity of the pin is checked. If the pin is wrong user need to try again. Once completed the user account is credited and the ticket along with the receipt to the user. Non-functional requirements The ticket system shall respond to user inputs to provide tickets and charge accounts in a timely manner. The system shall continue to function so long as roll of ticket paper is in the machine, and a network connection is provided for the destination database and credit transactions. Upon receipt of the destination from the user, the database shall be accessed to determine the distance from the units location, to the desired destination, and calculate the appropriate fee. The unit shall then prompt the user to input their card information, and the unit shall verify that the card is a credit card, is valid, and has sufficient credit to be charged. Upon successful verification, the unit shall print a ticket, and return to its ready state, for the next transaction to take place. The reliability this system relies on the durability of the physical user interface, the network connection in the area the system is placed, the size of the ticket rolls that the unit can accept, and the mecha nism for dispensing the tickets. The estimated time for a complete transaction would be about thirty seconds, giving twenty for the user interactions, five for validation and verification of the users account, and five for printing and dispensing the ticket. Use-cases Requirements validation process. Customer inserts her credit card into the ticket machine. card provider checks the card number. Then the machine asks for the pin-code. User enters the pin-code. Then the ticket machine requests database to validate the credit card. Ticket on processes. customer can use the ticket finaly.

Role of the Quakers in Uncle Toms Cabin by Harriet Beecher Stowe Essay

The Quakers and Uncle Tom’s Cabin     Ã‚  Ã‚           Ã‚  In this paper, I will examine the choice of using the Quakers as the angelic figures that become the saviors for the black race during the slave movement in Uncle Tom’s Cabin. While examining this topic, Harriet Beecher Stowe’s background of Puritanism becomes the focus for her motivation to change the world around her and her strict discipline of keeping spiritual values as part of her daily existence. The next stage to be discussed is her conversion from conservative Calvinist views to liberal ideals of social reform. This reform captures the spirit of Transcendentalism, the idea of the individual as a divine being changing society to meet with those ideals. Finally, I will touch on the belief of the Quakers and their history and how they became the model of godliness that is portrayed in Stowe’s novel.   In the Haggadah, God creates the world by his word, the twenty-two letters of the Hebrew alphabet descending from the crown of God engraved with a pen of flaming fire on the mind of Man (Barnstone 15). Many great writers strive to tap into this inspiration of divine light or intellectual genius to produce works of literary art. The written word from these writers possessed enough power to start revolutions, change public sentiment, and alter the rational thinking of the times. One such writer that changed historical events during the American Renaissance is Harriet Beecher Stowe. Her literary masterpiece, Uncle Tom’s Cabin, caused such enlightenment of the general public to push the United States into Civil War to emancipate the black race from the bonds of slavery.
