Essay about Security Wi Essay about Security: Wi-fi and Wireless Access Point Thesis What is my project (statistics.gov.uk/cci/nugget.asp?id=8) The UK has a very intensive Rail network system which spreads out across the whole country. It is used by millions of users. There is currently 21000 miles of track lied out across the network. According to statistics.gov.uk in the year 2010 1.32 billion people used the trains. This is statistic show the magnitude off the rail and that there is hugh potential in using is client base. According to national statistics 30.1 million adults in the UK where using internet every day, this is more then 60 percent of the adult population. In line with the amount of users now online they has also been a rise in users watching TV and Listening to the radio over the internet which in 2010 reached 17.4 million a day. Social networking has also risen in popularity with more then 65 percent of those online users using different types of social networking websites, chat rooms and blogs. What this shows is that we are living in the digital age were 70 percent of us need to be able to access information from the web. Now we now that there was 1.2 billion user of the rail network and we also now that more then half of the UK adult population use internet daily. We therefore argue the point that more then half of the rail network users use internet which means more then 600 million users of the rail network are internet users. Another statistic tells us that a recent study has shown that more then 80 percent of the adult population carry a mobile phone and 40 percent of those are wifi enabled. While on a trains user mostly access the internet via their mobile network provider, and this service is not great while on a fast moving train. User encounter loss of signal poor reception and rarely seem to have a good connection at all. The aim of my project is to provide a constant internet signal on a moving train utilising wireless connectivity. This will aloow users to connect to the internet while on the train using any wireless enabled devices such as Tablet Pc, mobile phone, laptop exe.... As wifi signal from one router is limited I will be intending to use many routers which will run along the train track. Power to them will be provided by the power terminals already existing along train track and phone-line. This will provide train customers to access internet constantly through out their journey with no loss of signal and speed. What will I use: Types of technology available for accessing the internet (http://en.wikipedia.org/wiki/Broadband_Internet_access) accessed on 16-02-2011 Mobile Broadband (explainthatstuff.com/mobilebroadband.html) There are two ways in which you can connect to a mobile broadband, if you have a smart phone which has HSPDA you can access fast mobile broadband or you can purchase a USB Dongle from most mobile network providers. Most major cities in the UK are covered by the 3G network Advantage The advantage of using mobile Broadband is that it has a larger coverage then wireless network. Where ever you can get a reasonable mobile connection you are more than likely to get a good mobile broadband connection. Disadvantage Mobile broadband has its downsides, as you are using the mobile phone provider’s network the quality of the signal you receive can vary from a good signal to a very poor signal, thus loss of connection occurs. When using mobile broadband on a train you can expect to lose connection very often as trains go under tunnels and bridges, this makes for a bad user experience. Satellite Broadband (http://computer.howstuffworks.com/question606.htm) (pcworld.com/article/17617/how_it_works_satellite_internet_access.html) High speed internet that uses a satellite dish on the receiving side similar to what satellite TV uses. The way in which internet is accessed is very similar to how Satellite television is received, a BIRD orbiting the earth beams down data to your dish. The way it works is you

The first value that comes out clearly from the book is that of â€Å"duty†. After the platoon arrived at their base in Afghanistan, â€Å"the insurgents attacked them with rocket fire† (Sean 12). The fire killed and even wounded several children. As a soldier, Parnell ran into the village to help one of the little girls. H e grabbed the girl and sprinted towards the First Aid Station.

As well, he believed that the other soldiers in the platoon must have had experienced a similar scene. This shows clearly how the soldier lived the value of duty. It is also a sign of commitment towards helping civilians and children. The value of â€Å"duty† requires that the soldiers do more than what is required of them. The other value that is evident from the book is that of â€Å"respect†. According to this army value, soldiers are supposed to treat other people well and with respect. Through respect, soldiers are able to appreciate the best in all the other people. During the 16 months in Afghanistan, the author explains how he encountered the noblest attributes of human spirit.

During the 16 months, Parnell was always ready to face adversity and danger. The team endured physical challenges and risked their safety in order to help others. The approach made it easier for them to attack the insurgents. According to the author, the platoon was fighting a strong infantry. The insurgents were seasoned and properly armed. It was only through courage that they would survive and win the fight.

Siege of Veracruz in the Mexican-American War

Siege of Veracruz in the Mexican-American War The Siege of Veracruz began on March 9 and ended on March 29, 1847, and was fought during the Mexican-American War (1846-1848). With the beginning of the conflict in May 1846, American forces under Major General Zachary Taylor won quick victories at the Battles of Palo Alto and Resaca de la Palma before advancing to the fortress city of Monterrey. Attacking in September 1846, Taylor captured the city after a bloody battle. In the wake of the fighting, he angered President James K. Polk when he granted the Mexicans an eight-week armistice and allowed Monterreys defeated garrison to go free.   With Taylor at Monterrey, discussions began in Washington regarding future American strategy. It was decided that a strike directly at the Mexican capital at Mexico City would be the key to winning the war. As a 500-mile march from Monterrey over rugged terrain was deemed impractical, the decision was made to land on the coast near Veracruz and march inland. This decision made, Polk was forced to decide on a commander for the mission. A New Commander While Taylor was popular, he was an outspoken Whig who had frequently criticized Polk publicly. Polk, a Democrat, would have preferred one of his own, but lacking an appropriate candidate, selected Major General Winfield Scott who, though a Whig, posed less of a political threat.  To create Scotts invasion force, the bulk of Taylors veteran troops were ordered to the coast. Left south of Monterrey with a small army, Taylor successfully held off a much larger Mexican force at the Battle of Buena Vista in February 1847. The sitting General-in-Chief of the US Army, Scott was a more talented general than Taylor and had come to prominence during the War of 1812. In that conflict, he had proven one of the few able field commanders and earned praise for his performances at Chippawa and Lundys Lane. Scott continued to rise after the war, holding increasingly important posts and studying abroad, before being appointed general-in-chief in 1841. Organizing the Army On November 14, 1846, the US Navy captured the Mexican port of Tampico. Arriving at Lobos Island, fifty miles south of the city, on February 21, 1847, Scott found few of the 20,000 men he had been promised. Over the next several days, more men arrived and Scott came to command three divisions led by Brigadier Generals William Worth and David Twiggs, and Major General Robert Patterson. While the first two divisions were comprised of US Army regulars, Pattersons was made up of volunteer units drawn from Pennsylvania, New York, Illinois, Tennessee, and South Carolina. The armys infantry was supported by three regiments of dragoons under Colonel William Harney and multiple artillery units. By March 2, Scott had around 10,000 men and his transports began moving south protected by Commodore David Connors Home Squadron. Three days later, the lead ships arrived south of Veracruz and anchors off Anton Lizardo. Boarding the steamer Secretary on March 7, Connor and Scott reconnoitered the citys massive defenses. Armies Commanders: United States Major General Winfield Scott10,000 men Mexico Brigadier General Juan Morales3,360 men Americas First D-Day Considered the most heavily fortified city in the Western Hemisphere, Veracruz was walled and guarded by Forts Santiago and Concepcià ³n. In addition, the harbor was protected by the famed Fort San Juan de Ulà ºa which possessed 128 guns. Wishing to avoid the citys guns, Scott decided to land southeast of the city at Mocambo Bays Collado Beach. Moving into position, American forces prepared to go ashore on March 9. Covered by the guns of Connors ships, Worths men began moving towards the beach around 1:00 PM in specially designed surf boats. The only Mexican troops present were a small body of lancers which were driven off by naval gunfire. Racing ahead, Worth was the first American ashore and was quickly followed another 5,500 men. Facing no opposition, Scott landed the remainder of his army and began moving to invest the city. Investing Veracruz Sent north from the beachhead, Brigadier General Gideon Pillows brigade of Pattersons division defeated a force of Mexican cavalry at Malibrn. This severed the road to Alvarado and cut off the citys supply of fresh water. Pattersons other brigades, led by Brigadier Generals John Quitman and James Shields aided in holding off the enemy as Scotts men moved to surround Veracruz. The investment of the city was completed within three days and saw the Americans establish a line running from Playa Vergara south to Collado. Reducing the City Within the city, Brigadier General Juan Morales possessed 3,360 men as well as another 1,030 offshore at San Juan de Ulà ºa. Outnumbered, he hoped to hold the city until aid could arrive from the interior or the approaching yellow fever season began to reduce Scotts army. Though several of Scotts senior commanders wished to attempt a storming of the city, the methodical general insisted on reducing the city through siege tactics to avoid needless casualties. He insisted that the operation should cost the lives of no more than 100 men. Though a storm delayed the arrival of his siege guns, Scotts engineers including Captains Robert E. Lee and Joseph Johnston, as well as Lieutenant George McClellan began working to site gun emplacements and enhance the siege lines. On March 21, Commodore Matthew Perry arrived to relieve Connor. Perry offered six naval guns and their crews which Scott accepted. These were quickly emplaced by Lee. The next day, Scott demanded that Morales surrender the city. When this was refused, the American guns began bombarding the city. Though the defenders returned fire, they caused few injuries. No Relief The bombardment from Scotts lines was supported by Perrys ships offshore. On March 24, a Mexican soldier was captured carrying dispatches stating that General Antonio Là ³pez de Santa Anna was approaching the city with a relief force. Harneys dragoons were dispatched to investigate and located a force of around 2,000 Mexicans. To meet this threat, Scott dispatched Patterson with a force which drove off the enemy. The next day, the Mexicans in Veracruz requested a ceasefire and asked that women and children be allowed to leave the city. This was refused by Scott who believed it to be a delaying tactic. Resuming the bombardment, the artillery fire caused several fires in the city. On the night of March 25/26, Morales called a council of war. During the meeting, his officers recommended that he surrender the city. Morales was unwilling to do so and resigned leaving General Josà © Juan Landero to assume command. On March 26, the Mexicans again requested a ceasefire and Scott sent Worth to investigate. Returning with a note, Worth stated that he believed the Mexicans were stalling and offered to lead his division against the city. Scott declined and based on the language in the note, began surrender negotiations. After three days of talks, Morales agreed to surrender the city and San Juan de Ulà ºa. Aftermath Achieving his goal, Scott only lost 13 killed and 54 wounded in capturing the city. Mexican losses are less clear and were approximately 350-400 soldiers killed, as well as 100-600 civilians. Though initially chastised in the foreign press for the inhumanity of the bombardment, Scotts achievement in capturing a heavily fortified city with minimal losses was staggering. Establishing a large base at Veracruz, Scott quickly moved to get the bulk of his army away from the coast before yellow fever season. Leaving a small garrison to hold the city, the army departed on April 8 for Jalapa and began the campaign that would ultimately capture Mexico City.

The Different accents across the UK Literature review

The Different accents across the UK - Literature review Example (Nikunen, 2011) says that The English language has more than one dialect, dialects affect the way pronunciation happens and is therefore a ground for accentuation. The United Kingdom has the most variety of English accents. Some of the accents of the English language include the received accent. The received accent has been popular in the United Kingdom since the eighteenth and nineteenth century. The characteristics of this accent are evident in common omission of the letter ‘r’ after vowels in words like father. The word is pronounced as fuhthuh while normally in the American dialects the ‘r’ is emphasized so that father is pronounced as fatherrrr. Another feature involves the trap a bath, it is evident when words like can’t are pronounced with a quick almost posed –a-. The received accent is clearly distinguishable from American and Irish accents and is especially taken for the Standard English of the people From the United Kingdom. The rece ived accent is also popular as the Queen’s English or BBC English. Moore (Nikunen, 2011). Other accents include: the southeast British accent this accent relates to American accents. It developed from London English and has spread to other regions like East Anglia and Southeast England. The northern England accents include the Midlands English that includes accentuation common in Manchester and Liverpool, the inner regions of Yorkshire and Leeds. Its features includes lengthened syllables where vowels in words as ride and play are persistent so that they are pronounced as raaaid, ra:id, and plie. The Geordie accent is popular in the northeast of the United Kingdom. It also describes a group of people and is distinct among the regions in the northern east of England. It is characterized by the presence of /au/ which makes words like gout sound like ‘goot’. It also involves the /ai/ which is heard when kite is pronounced as ‘kate.’ The kate pronunciati on renders the accent an American relation (Subedi, 2008). The Welsh accent involves pronunciation by people who especially originate from the Wales (Bishop, 2005). It is characterized by a certain musicality that stresses on all syllables of a word. The Received accent is a tapered version of the Welsh accent. The accent has remained very popular over modern times along with others like the Scottish English. The Scottish accent has a lot of /ei/ and /ou/ and is heard in the pronunciation of words goat which sounds like go:t or got while face is sounds as feis. Scottish English has been influenced by the Scots language even though the two are different languages all in all (Bishop, 2005). Cockney is another popular accent among the UK English variety of accents and is used in London. It is probably the most popular accent after the Received accent. It is however camouflaged amongst other English accents in the regions around that it is not easy to tell apart from the received accent . It is notable from pronunciation of words like cat, which sounds as ‘cet’. This is because the vowels are especially raised. Another feature in vowels include a shift so that words like day sound like die and words like better are pronounced as ‘be’uh’ from glottal involvement during pronunciation. A unique feature of the Cockney

TESCO and the JIT Philosophy - Essay Example While it is not clear which supermarket pioneered this revolutionary supply chain model, which is now adopted by many in the industry and is considered as a standard of best practice, many attribute it to Tesco’s reforms set up late in the 1990s. This is a report on Tesco’s supply chain management practices, which is recognized to be designed after Toyota’s â€Å"just in time† (JIT) model. Specifically, this report will compare JIT principles to Tesco’s business practices and assess the latter’s efficacy in the navigation of the challenges Tesco faces amidst the internationalization of both suppliers and its market. II. Relevant Operational Theories and Principles Supply Chain Management Fundamentally, supply chain management is the framework by which processes, structures, managements elements in the value chain is integrated and coordinated. It is crucial in the drive for competitive advantage and concerns the alignment of management practices into what the requirements of the customers. Seuring (2003) outlined the basic characteristics of the concept: †¢ Supply chain management is primarily an integration-oriented logistics management concept, characterized by the strategic, cooperation-oriented and interorganizational initiatives; †¢ The task of the concept is to manage the supplier-buyer relationships, particularly streamlining the complex chain and network involved; The goal is to align all activities to satisfy the requirements and needs of customers and reduce costs and enable the organization to take advantage of opportunities; The focus is to realize efficiencies and the expansion of covered activities beyond logistics, including management components and information flows among the supply chain partners. (p169-168) Lambert was able to depict the framework in the following model: Supply Management Framework (Lambert, 2000, p70) SCM Tools Supply chain management tools are essentially systems and solutions that are designed to enhance it so that the processes produce value for customers either in facilitating, integrating, coordinating, controlling, optimizing and so forth. An excellent example is technology. Through this tool, SCM is able to automate order processing, warehousing, among other stages in the value chain and make centralization possible and more efficient. Tesco’s continuous replenishment system is a specific example. Th en, there is also the so-called electronic data interchange

World History Galileo Essay Example | Topics and Well Written Essays - 750 words

World History Galileo - Essay Example World History – Galileo During his work in astronomy, Galileo found many things that supported the view of the Polish astronomer Nicholas Copernicus that the earth was not the center of the universe, but a heavenly body that orbited the sun. This was against the belief that the earth was the center of the universe as put forward by Ptolemy and taken as true by the Catholic Church. The Catholic Church declared the Copernican Theory as false. Thus Galileo’s support for the Copernican Theory was against the doctrines of the Church (3). Galileo did not want to oppose the Church, but some of his writings were against Church held views and his opponents made brought these to the notice of the Church to draw the support of the powerful Church in harming Galileo. It is against this background that Galileo wrote the letter to the Grand Duchess Christina. (4). In this letter Galileo defends his position on the support of the Copernican theory, as it is based on his own observations. His opponents are unable to prove otherwise and have fallen back on the support of philosophy and the sayings in the Bible to prove him wrong. Galileo takes the position that a true interpretation of the Bible would enable the world to understand that there is nothing unacceptable with his views on the Copernican theory. â€Å"I think in the first place that it is very pious to say and prudent to affirm that the holy Bible can never speak untruth-whenever its true meaning is understood†.

The Judeo-Christian Ethic is Ruining Our Environment Essay

The Judeo-Christian Ethic is Ruining Our Environment - Essay Example Another part of the damaging equation lies in the Christian belief that we are to go forth and multiply, therefore there is ban on contraceptives instituted by the Catholic church. This is another part of the Judeo-Christian belief that is damaging to our environment, and this belief is perhaps most damaging at all. This essay will examine the man-made causes of global warming, and the effects of global warming. This essay will also examine the way that we treat our animals, which is a part of the equation that would be inherent in White's essay. Finally, this essay will look at the effects of overpopulation, which, if it gets much more out of hand, will be the effective end of environment. All of these problems can be directly traced to Christian ethos of dominion over the environment, animals, and the command for the human race to go forth and multiply. The Bible and Animals White's argument centered around the fact that the Bible has been used by humans to justify treating nature and our environment in a way that shows that animals and natural resources were put on this earth simply to save man. He approved of the way that St. Francis of Assisi saw the animals – St. Francis of Assisi thought of the animals as being God's creatures, with souls, and that they were put on this earth not to serve man, but because God created them the same way that he created us. This meant that St. Francis respected the animals as sentient beings with souls. This is clearly not the way that man thinks of animals, if one considers factory farms. For instance, the ethicist Peter Singer, who believes the way that St. Francis did, that animals were not put on this earth to serve us, but they were created in their own right, details how humans treat animals. For instance, he states, in his book The Meat and Milk Factories: The Ethics of How We Eat (2006) that pigs are kept in a crate that is so small that they cannot turn around. Without even hay to sleep on, this is all these pigs know – this tiny crate. The breeding sows are kept in tiny crates that are only a foot longer than their bodies, while being forced to have litter after litter. Male pigs are castrated with an anesthetic. Cows are not treated much better. For instance, the veal cow is put into a dark crate for 16 weeks. During this time, it has a tied neck and is basically starved of iron, so that it becomes anemic. Therefore, it is certain that man believes that animals are simply on this earth to be exploited by humans. Otherwise, there would be a greater outcry about how our animals are treated. Instead, the issue is mostly swept under the rug. In the recent United States Presidential election, the issue of animal rights and factory farms did not come up. Once. That is because of the belief that man has dominion over the animals. Because animals do not have soul, and because man is supposed to have dominion over them, that means that we can treat them any way that we want to treat th em, and forget that they have feelings and can sense pain and fear. But the fact that factory farms are cruel is just one part of the equation. The other part is that they are bad for the environment. Thus, the factory farming lends credence to Smith's overall thesis, which is that the Judeo-Christian ethic is bad for the environment. Michael Pollan explains why this is so. According to Pollan (2008), factory farms harm the environment because the animal waste is in such abundance, because meat in general is in such abundance, that it is no longer fertilizer, but a pollutant. The reason for this is because the
