Internet History Essays - Computing, Technology,

Internet History Starting out as a small military experiment some 35 years ago, the Internet is quickly becoming one of the most popular forms of communication. With a present population of about 40 million users world wide, it seems to have a very promising future. Uncensored and almost impossible to monitor, it's a breeding ground for all sorts of offensive and derogatory information. On the other hand, it is probably the biggest single source of data in the world brought home into your personal computer. Will this form of communication survive in the future, or will it simply die out like many others have in the past? History The first nodes of the Internet were built 36 years ago by the RAND corporation. They faced the problem of keeping communication between U.S. authorities active in the aftermath of a nuclear war. The country needed a command-and-control network. The biggest problem was protecting the main server, which could be knocked out by a single atomic warhead. RAND came up with the solution in 1964. The new network would have no central authority, and secondly, it would be designed to operate in shambles. " During the 60s, this intriguing concept of a decentralized, blastproof, packet-switching network was kicked around by RAND, MIT and UCLA. The National Physical Laboratory in Great Britain set up the first test network on these principles in 1968. Shortly afterward, the Pentagon's Advanced Research Projects Agency decided to fund a larger, more ambitious project in the USA. The nodes of the network were to be high-speed supercomputers (or what passed for supercomputers at the time). These were rare and valuable machines which were in real need of good solid networking, for the sake of national research- and-development projects." (Sterling 1-2) The first was put in place during the fall of 1969. By December of the same year four nodes were installed. They were connected by dedicated high-speed transmission lines. This allowed the computers to communicate and be programmed from one of the other computers. In the year of 1971 there were 15 nodes, and by 72 there were 37. This number kept increasing rapidly as the years passed. The network was also becoming more of a person to person way of communicating. Many military personnel began using it as a way to gossip with friends instead of a way to transmit documents and projects. This became even more evident in the following years. How it works The Internet may seem a very complex form of communication but that is not really the case. First, you must have a reasonably fast computer (80386 or higher) with a modem and a phone line. The next step is to contact your local Internet provider and get him to give you a password and an SLIP address. At this time you will also be given the software to get you started. All of this costs about 140 dollars, depending on how many hours you wish to purchase. "We charge using an hourly rate because it gives our users more flexibility with their time. When run on a monthly payment, you are limited to an hour a day, whereas with our system you can use any amount of time whenever you want" (Schulmeister). The costs are as follows: 10 hrs-$30.00 20 hrs-$50.00 40 hrs-$80.00 60 hrs-$90.00 Once you have your software installed and want to start "surfing the net," you must first login to the server (located at the Northwest Community College) by dialling in its phone number using a specific program. The two local numbers are 638-1543 and 638-1593. Even with the two numbers, the server is often busy because of the constantly increasing number of users in our area. These numbers can be used by a number of people at a time, not just two. Once connected to the college server, you travel down to a larger server in Vancouver, and from there you can access any other computer connected as long as your server has permission to do so. Diagram: How the Internet works Impact on Society The Internet is just starting to have a large impact on society. It seemed to come out of nowhere, popping up in magazines and on the news. The Internet is now becoming an influential communications medium to

Jfk Assassination Essays - Single-bullet Theory, Warren Commission

Jfk Assassination Essays - Single-bullet Theory, Warren Commission Jfk Assassination Conspiracy or Single-gunman? Adolf Hitler, the Nazi dictator of Germany during World War II, once said, The bigger the lie, the more people will believe it. Although this may sound absurd, we can see many examples of this in the world's history. One example would have to be the John Fitzgerald Kennedy assassination. For over thirty years the people of the United States were led to believe that a single gunman had shot and killed Kennedy in Dallas on November 22, 1963, at 12:30 p.m... However, in this paper, I will dispute the ancient analization of the facts that show a single gunman was involved, and try to show that a conspiracy must have taken place. According to the old facts regarding the case of the JFK assassination, Kennedy was killed by a single gunman. On November 22, 1963, at 12:30 p.m. CST (Central Standard Time), Kennedy was riding in an open limousine through Dallas, Texas. At this time, Kennedy was shot in the head and neck by a sniper. He was then taken to Parkland Memorial Hospital, where he was pronounced dead. Later, police arrested Lee Harvey Oswald, a former U.S. Marine, at a nearby theater. By the next morning, Oswald was booked for the murder of President John F. Kennedy. Two days later, Oswald was killed by Jack Ruby, a Dallas nightclub owner, while he was being moved from the city to the county jail. At a glance, the above story sounds as if this should be an open-and-shut case. After all, according to the facts above, Oswald must have killed Kennedy. However, you must take a deeper look into this case. Many people who witnessed the murder of John F. Kennedy dispute the facts above, saying that they heard shots from places besides the book depository, and other things that may contradict what is stated above. One of these witnesses, Abraham Zapruder, captured the entire assassination on his Bell and Howell video camera. This movie, cleverly called the Zapruder Film, is the single best piece of visual evidence in this case. In order to more clearly understand the Zapruder Film, it is necessary to break it down into frames. The particular Bell and Howell movie camera that Zapruder was using ran at about twenty frames per second. When using this frame system, you must remember that all shots were actually fired several frames before the number that is assigned to them. For example, the fatal heart wound, called Z313, was probably fired at Z310, since it took 2-3 frames at about twenty frames per second for the bullet to reach the victim. Also, you must remember that sound travels very quickly at an impossible speed. When keeping this in mind, it is expected that witnesses heard the shot at some point after the bullet passed. The following shows a break down of the frames of the Zapruder film: The Presidential limousine first comes into view at frame 133 (the starting point of this timeline.) The first shot at (or just before) Z187 would have passed through both Governor Connally and the President. The second shot, which passed above the limousine at Z284, missed the President and hit the curb near witness James Tague. This caused his minor wound. At Z313, the fatal shot occurs, which blew out major portions of the Presidents brain and skull. - A fourth shot occurred at Z323 (slightly 1/2 second after the fatal wound at Z313). Due to the proximity of this report to the one at Z313, as well as it's more distant origin, most witnesses were unable to hear this shot. Therefore, the above is when the bullets hit either Kennedy or Connally, or passed through the frames of the Zapruder film. Of the one-hundred seventy-eight witnesses at Dealey Plaza, one-hundred thirty- two said that they hear exactly three shots. If Oswald was a single gunman, it would have taken him at least 2. 3 seconds to reload his Mannlicher Carcano rifle. However, the general consensus of the witnesses is that they heard a single shot, followed by silence, with the second and third shots bunched together. For example, Lee Bowers, one of the witnesses, testified, I heard three shots, one, then

An Overview Of Quality By Design Engineering Essay

An Overview Of Quality By Design Engineering Essay Since there is immense competition globally and growing impact of Information technology, the pharmaceutical industry should need to improve its performance. The industry should implement newer technologies that can effectively reduce cost of production and at the same time improves product quality and regulatory compliance. Quality by Design is a newer approach that has been offered by the United States Food and Drug Administration (USFDA) which if understood well and implemented properly can save considerable amount of time and cost and at the same time can improve final product quality and regulatory compliance which can increase the speed of product to reach in to the market. This article discusses the background of quality by design concept, Building blocks of Quality by Design, and its approach across the product life span and benefits that it offers. Introduction: In 2002, the U.S. Food and Drug Administration (FDA) published a guidance document for pharmaceutical companies o n cGMP for the 21st century. This guidance document expressed a strong desire that companies should build quality, safety and efficacy in to their product. This concept is now known as Quality by Design (QbD). Till now, the meaning, benefits and impact of quality by design is confusing to many people. Some says that it is a newer way to develop drugs, biologics and devices; some says that it can shorten the production cycle; some says that it provides more business flexibility but no one knows what it is exactly. Some people do not even know that where, when and how should it be applied? Initially there are so many companies who tried to adopt Quality by Design concept but confusion gave way to frustration. Background of Quality by Design: Quality by design (QbD) is the concept first developed by the famous quality expert named Joseph M. Juran in his 1992 book called â€Å"The New Steps for Planning Quality in to Goods and Services†. He believed that quality could be planned in the very first stage of the production rather than final testing. The concept was first used in automobile industry. There is one article published in June 2007 titled â€Å"Elucidation: Lessons from the Auto Industry† says that Toyota Automobiles was the first company who implemented many Quality by Design concept to improve their automobiles in 1970s. That is why we can say that Quality by Design concept is new only for FDA regulated industries and not for other industries like technology, aeronautics, telecommunications etc. In other words, we can say that the computer we use, the phone we answer, the airplane we ride, the car we drive and the camera we use are all products of Quality by Design but we cannot say that whatever tablet we ingest and whatever biologics we use are the products of Quality by Design. In 1990s, many of the medical device manufacturing company has implemented Quality by Design aspect which resulted in reduced risk and manufacturing cost and at t he same time increased patient safety and product efficacy. From the success of QbD aspect in medical device manufacturing, the FDA officials felt that this concept has to be applied to drugs and biologics also. So, the internal discussion in FDA started in late 1990s and finally they published a concept paper in 2002 on cGMP in 21st century. With the huge help of some pharmaceutical companies, pilot programs were started to share the Quality by Design application and process understanding with the other companies.

Big Issues - Research Paper Example conditions surrounding their medical situation will involve the kind of medical attention required, and the capability of the caregiver to administer the requirements. Does the primary medical professional have the right to decide? William Coch believes so. Firstly, if an elderly has no relative, he should be in a nursing home. However, when there are relatives involved, a lengthier and more complex decision-making process takes place. Based on Coch’s experience, most of his patients look to him for the final decision. He positions it as â€Å"doctor’s orders.† If such is the paradigm, it takes away the emotions involved from the point-of-view of abandonment vs. capability to care. It objectifies the decision, and makes it a part of the elderly patient management (Frontline, 2006). Does the immediate relative have the right to decide? If the presence of a relative is available, then by all means should be consulted. However, the primary medical professional still gets involved with the conversation, if at a minimum to provide a professional prognosis of the elderly’s medical condition, and if requested, can provide a professional medical opinion as an advocate (Frontline, 2006). In conclusion, the best decision will be made by the three players: the sensible elderly, the primary health provider and the primary caregiver relative. It should be a decision based on consensus, where all parties will agree to an objective – the level of quality for end-of-life. US Bureau of Census (2010).

The Undead Research Paper Example | Topics and Well Written Essays - 500 words

The Undead - Research Paper Example hemselves are only moderate and somewhat ambiguous, and the emphasis is on those telling the stories and experiencing them being not really sure whether they encountered ghosts with dead certainty (Goldstein, Greider, and Thomas, 2007, pp. 29-31): The drama comes from the subject matter and the manner in which people tell the stories rather than from the extraordinary behavior of the supernatural beings. In the oral tradition, people commonly report merely feeling some type of â€Å"presence†, a cold feeling in the room, or strange noises and nothing more† (Goldstein, Greider and Thomas, 2007, p. 29). The same observation is made with regard to the subtle and ambiguous reality of ghosts as they are rendered in American culture. The take is that in American culture, the reality is something that cannot be fixed with the certainty of fact, but is embedded within the hazy and deliberately ambiguous stories that people tell each other when they relate their experiences about ghosts. This is the case, for instance, in observations of how ghosts are portrayed in American literature that represents the best of American culture through the ages (Lewis, 2005, pp. 33-34): James thus poses, in somewhat clumsy form, the sorts of questions that will bedevil interpreters of his later ghost stories. Was the fathers death a natural result of his anxiety over the fake haunting, or did the narrators tearing of the daughters veil somehow, supernaturally, cause it?... Jamess refusal to answer these questions provides an early example of the workings of what I shall call â€Å"shared fictions† in his later ghost stories (Lewis, 2005, p. 34). Apart from these American cultural artifacts there are also insights to be gleaned in cultural renderings of ghosts in America as they pertain to the conceptions of ghosts reflected in rituals involving the dead and involving ghosts in general, such as Halloween. In Halloween conceptions of ghosts, they are lumped together with witches who

Fossil Story Essay Example for Free

Fossil Story Essay Northeastern Illinois has a great deal of geological history hidden beneath the surface. If you just take a trip to the Larson Quarry or even Pit 11 you can find some interesting rock formations as well as fossils in them. But, if you cannot get to these areas, this paper can tell you what you can find in 5 different locations in Northeastern Illinois. We will be looking at Larson Quarry, Thornton Quarry, Mazon River, Pit 11, and the Glacial Drift which is at Palos Hills and throughout the surface of the Chicago area). The first stop is the Larson Quarry. This is located near DeKalb, Illinois. The specific coordinates are 42? N, 88? 35’ W at 920 feet. This site contains specimens from 450 million years ago which include trilobites like Flexicalymene, brachiopods like platystropia, rafnesquina, leptaena, the horn coral streptelasma, an unnamed bivalve, bryozoans, various crinoid stem parts, the cephalopod endoceras, and the gastropods cyclonema and malcurites. The rock types and formations that were found around these fossils were Cincinnatian Maquoketa Shale and Galena Dolomite. â€Å"The Maquoketa shale, which contains seams of argillaceous dolomite†¦and ranges from highly to slightly weathered, with the highly weathered portions having the consistency of a stiff clay and are extremely fissile† (Preber). These fossils were preserved by replacement as well as mold and cast. The Mazon River, which is near Morris, Illinois is located at 41? 20’N, 88? 30’W at 525 feet. This site had fossils from 290 million years ago and included seed ferns like alethopteris and neuropteris, true fern Pecopteris, horsetail rush parts calamites (trunk), and annularia (leaf whorl), lycopod tree (club moss) parts and bark lepidodendron, and leaf lepidophylites. The rock types were shale and sandstone as well as coal and the formation was Francis Creek. The Illinois State Museum writes in an article about how Francis Creek formation is formed: â€Å"Much of the area that we now call Illinois was a mixture of swampy lowlands and shallow marine bays. From the northeast flowed at least one major river system. The river(s) built large deltas through the low swamps and into the shallow bays. The mud that the river(s) carried was deposited in these deltas and bays. This mud turned into a rock called the Francis Creek Shale†. The preservation type was impressions in concretions. Next is Pit 11 which is the Mazonia/Briadwaood State Fish and Wildlife area at 41? 15’N, 88? 15’W at 590 feet. These specimens were found from 290 million years ago. The fossils include the same basic plants as the Mazon River. They also include jellyfish like the essexella, the shrimp belotelson, clams like edmontia and aviculopectin, an unnamed marine annelid worm, a possible fish fossil coprolite, the infamous Tully Monster: tullymonstrum, and the echinoderm sea cucumber holothurian. The rock types that held these fossils were shale and sandstone, as well as coal. These were in a Francis Creek formation. These fossils were preserved by impressions in concretions. It becomes quite apparent that there are certain biases in how and what fossils are preserved. Some species, notably Pecopteris unita, are found with fertile structures nearly half of the time while others like the more common true fern, Pecopteris acadica, are rarely seen with fertile structures being preserved at all† (Mazon Creek†¦). This tells us how these fossils were formed. Thornton Quarry, at coordinates 41? 35’ N, 87? 35’ W at 590 to 250 feet, is located on the south side of Chicago. This Quarry was formed 420 million years ago and includes fossils such as the trilobite calymene, brachiopod pentamerus, corals like favosite and halysites, an unnamed crinoid stem and the cephalopod moorecoceras. The rock types that were here were limestone-dolomite in Niagaran Racine Dolomite with fossils in mold and cast. â€Å"The most famous reef unearthed in the Chicago area is the coral reef†¦Debris from the growing reef began to be deposited and cemented. The reefs contained sea lilies, animals resembling horseshoe crabs, and ancient ancestors of squids and octopuses up to ten feet long. The ashy, gray-white limestone mined from the Thornton Reef contains the fossils of these animals† (Herweck). The reason that there are multiple types of coral is because this area was at the bottom of the Silurian Sea and molded well into the limestone. Lastly, we visit Palos Hills which includes the Glacial Drift. This area was from ~15,000 years ago and showed deposits of unconsolidated pebbles, sand, silt ad clay which contain mixed rocks of 400 million to 1 billion years old at 41? 41’N, 87? 50’ W at 772 feet. The fossils found here are mammoth or mastodon remains that are preserved as unaltered hard parts. There are also mixed marine fossils including crinoid stems, brachiopods, corals like hexagonaria (Petosky Stone) and trilobite parts, where were preserved as mold and cast r replacement. The glacial till include striated rocks composed of a mixture of many types including sedimentary (limestone/dolomite), igneous (granite, basalt) and metamorphic (gneiss). The formation was Valparaiso Moraine. â€Å"At this time, glacial ice covered the entire Chicago region†¦. the active ice sheet retreated into the Lake Michigan basin, although stagnant, melting ice remained behind. The ice then rapidly re-advanced to the†¦Valparaiso moraine in the western Chicago region† (Grimm). The glaciers that were in Chicago made a big impact on picking up rocks and sand and dirt from other regions and bringing it into the area, which is a reason why you may find interesting things in the area and that rocks age from 400 million to 1 billion years ago. The areas that we can find an assortment of fossils and rock formations are abundant in Illinois and have a wide variety of ages. From this summary, you can see what type of rock are around Northeastern Illinois and what type of animals, plants, and rocks were around from different periods and what type of environment they must have lived in.

William Butler Yeats Essay -- essays research papers

William Butler Yeats. William Butler Yeats was the major figure in the cultural revolution which developed from the strong nationalistic movement at the end of the 19th century. He dominated the writings of a generation. He established forms and themes which came to be considered as the norms for writers of his generation. Yeats was a confessional poet - that is to say, that he wrote his poetry directly from his own experiences. He was an idealist, with a purpose. This was to create Art for his own people - the Irish. But in so doing, he experienced considerable frustration and disillusionment. The tension between this ideal, and the reality is the basis of much of his writing. One central theme of his earlier poetry is the contrast between the aims he, and others, such as Lady Gregory, had for their movement, and the reality. He had hoped to provide an alternative to nationalism fuelled mainly by hatred for Britain, through the rebirth and regeneration of an ancient Irish culture, based on myth and legend. Instead, he found that the response of the newly emerging Irish Catholic middle class to their work, varied between indifference and outrage. On the one hand, their indifference was displayed by their refusal to fund a gallery for the Hugh Lane collection of Art, and on the other hand, they rioted i n outrage at Synge's Playboy of the Western World. The tension between Yeats' ideal, and the reality is developed in the Fisherman and September 1913. Both these poems deal with Yeats attempts to bring Art to the people of Ireland, and the negative response of Irish society. September 1913. Here, Yeats directs his passionate rage against the Irish Catholic middle class. He perceives them as Philistines, whose values are monetary and religious, not artistic. His scorn for their petty money grubbing - dry the marrow from the bone and their narrow selfish piety Prayer to shivering prayer is set in contrast to his admiration for the heroes of old. Yet they were of a different kind. These patriots had loved Ireland with a passion which consumed them, and for which no sacrifice was too great. For whom the hangman's rope was spun. But the present materialistic age has no place for such men of courage and idealism. Their age is past. It's With O'Leary in the grave. Self sacrifice and patriotism are dead. Consequently, he dismisses the Ireland of his day with ... ...Blind Man stole the bread' were 'Heart mysteries' -that is, having their origins in human emotions, he sacrificed the man to the artist: 'Players and painted stage took all my love, And not those things that they were emblems of". The joy of creation increasingly absorbed him, not the living of life. Character isolated by a deed To engross the present and dominate memory. These images were 'masterful' - under the Ringmaster's control. And they 'grew in pure mind' -increasingly they were the product of his intellect, not his emotions. But now they have gone - they've deserted him, or perhaps he has deserted them, seeing them in all their artificiality. So he is left with no option but to return to what he has avoided - the world of feeling, of emotion. His ladder out of that tangled world of human emotion, has gone. He's left at the bottom of the ladder, with his feet on the ground. He uses the powerful metaphor of litter - 'old kettles, old bones, old rags' to suggest the ugliness of human feeling. But, he must confront the reality of life and living at last - he must return to the source of all art, the world of human emotion- 'The foul rag and boneshop of the heart'.
