Aristotle Essay example -- Biographies Bio Biography

Aristotle was born in 384 BCE at Stagirus, a Greek colony and seaport on the coast of Thrace. His father Nichomachus was court physician to King Amyntas of Macedonia, and from this began Aristotle's long association with the Macedonian Court, which considerably influenced his life. While he was still a boy his father died. At age 17 his guardian, Proxenus, sent him to Athens, the intellectual center of the world, to complete his education. He joined the Academy and studied under Plato, attending his lectures for a period of twenty years. In the later years of his association with Plato and the Academy he began to lecture on his own account, especially on the subject of rhetoric. At the death of Plato in 347, the pre-eminent ability of Aristotle would seem to have designated him to succeed to the leadership of the Academy. But his divergence from Plato's teaching was too great to make this possible, and Plato's nephew Speusippus was chosen instead. At the invitation of his friend Herm eas, ruler of Atarneus and Assos in Mysia, Aristotle left for his court. He stayed three year and, while there, married Pythias, the niece of the King. In later life he was married a second time to a woman named Herpyllis, who bore him a son, Nichomachus. At the end of three years Hermeas was overtaken by the Persians, and Aristotle went to Mytilene. At the invitation of Philip of Macedonia he became the tutor of his 13 year old son Alexander (later world conqueror); he did this for the next five years. Both Philip and Alexander appear to have paid Aristotle high honor, and there were stories that Aristotle was supplied by the Macedonian court, not only with funds for teaching, but also with thousands of slaves to collect specimens for his studies in n... ...sofar as they are properties of all existence. Aristotle argues that there are a handful of universal truths. Against the followers of Heraclitus and Protagoras, Aristotle defends both the laws of contradiction, and that of excluded middle. He does this by showing that their denial is suicidal. Carried out to its logical consequences, the denial of these laws would lead to the sameness of all facts and all assertions. It would also result in an indifference in conduct. As the science of being as being, the leading question of Aristotle's metaphysics is, What is meant by the real or true substance? Plato tried to solve the same question by positing a universal and invariable element of knowledge and existence -- the forms -- as the only real permanent besides the changing phenomena of the senses. Aristotle attacks Plato's theory of the forms on three different grounds.

What is digital television?

Digital television offers a superior format by broadcasting sharper pictures and clearer sound. Also, digital television is versatile and can be used for a variety of purposes. Furthermore, with digital television, there is an efficient use of the spectrum for a variety of essential services such as police departments, emergency services, delivery companies, etc. This is because digital signals free up bandwidth and provide space. Jerome Adda and Marco Ottaviani write that, â€Å"Digital compression technology allows roughly six times as many channels to be broadcast with the same amount of spectrum used by one analogue channel.† (169)Digital television is a new advanced technology which is used to send and receive broadcast signals (both picture and sound). Digital television supports the following services: subscription TV programming, computer software distribution, data transmissions, teletext, interactive services and audio signals. Digital television is superior to analo g television because it is more accurate, versatile and compatible with other electronic media such as computers, satellites, mobile phones, etc. Digital television has certain technical specifications which set it apart.Joel Brinkley writes that these qualities of digital television have made it very popular and attractive. These are as follows: progressive scanning, square pixels, enhanced frame rates, added lines per frame, different aspect ratios, different aspect ratios, and clearer sound. Progressive scanning is a better technical format than interlaced scanning. The former allows for smooth sequence of video frames. With this, progressive scanning which is used in digital television allows for compatibility between digital television and computers.With square pixels, digital television has 1920 pixels per line and a total of 1080 lines per frame. This gives pictures on digital television a sharper resolution. With the enhanced frame rates digital television allows more frames per second. As a result motion portrayed on digital television is more realistic- the more frames per second, the more realistic motion will be. The aspect ratio for digital television is 16:9. This aspect ratio of digital television gives larger pictures and makes viewing more natural. Digital television produces clear sound because it uses five channels of discrete compact disc quality audio.Apart from the aforementioned, digital television presents a number of advantages which hitherto were unavailable with analog television. With digital television there is a wider choice of programs available for the audience to choose from. Digital television presents a large number of channels and this does not affect the quality of any the programs on the channels. Furthermore, on digital television, the audience is able to engage in other activities such as electronic shopping, betting, etc. Digital television is also a channel for reaching the audience with information services because th e medium is not restrictive.With digital television, the audience is able to browse the Internet. Also, digital television also provides telephone services and is compatible with computers and mobile phones. The technology of digital television is very compatible with many other digital devices. This ability makes it possible to achieve a high level of interactivity on digital television. Viewers are able to vote on digital television using remote controls, as well as achieve two way communication with the mother station for various purposes.In terms of income generation, digital television offers an efficient way of monitoring subscriptions and ensures that only people who pay receive the service. In this way digital television is very useful to manager so broadcast stations. From this time on, there has been steady growth in digital television. Toward this end, there has been a deadline set to ensure a transition from analog broadcasting to digital broadcasting in the United State s. Other developed countries of the world have also set dates for this transition. Origin of digital television.Although digital television is often perceived as a recent phenomenon, the journey to where it is now began a long time ago. According to Alexander B. Magoun the first digital television system originated between 1956 and1961. It was started by Richard Webb, an ex RCA engineer, who was working on contracts for encrypted video communication contracts required by the military and National Security Agency in the United States of America. Magoun writes that Richard Webb was able to obtain digital signals when he â€Å"converted the analog brightness data from a monochrome video signal into a binary bitstream.†This binary bitstream was encrypted by the digital computers used by the US Military at the time. Webb based his work on the knowledge and experience of other engineers from other companies. Webb found the modulation technique of Frank DeJager (an engineer from Phi llips) very useful. Originally this modulation technique was used in sound recordings. Using the modulation technique, Webb and his team in Colorado encoded the relative brightness of each pixel (they did not encode the absolute brightness). In doing this, they saved significant bandwidth and created a single channel for data transmission.Thus digital television came into being. The first digital television station was established in the White house when President Dwight Eisenhower was in office. This system remained in place in the white house till 1979. What is Analog Television? Analog television encodes pictures using varying single voltage and radio frequencies. Analog television receives and displays broadcast signals that are transmitted using the radio waves. Alexander B. Magoun notes that in analog television, the video component is transmitted using amplitude modulation (AM) while the audio component is transmitted using frequency modulation (FM).Analog television is ineff icient because it is subject to interference. When this interference happens, the pictures become grainy and picture quality is greatly diminished. The quality of analog signals is dependent on the distance between the receiver and the transmitting station. On analog television, the broadcast signal continues to weaken as distance increase from the broadcast station to the receiver. When this happens, the pictures which appear on the analog television become ghosty with grains (it appears to be snowy). This is often referred to as a snowy, fuzzy or ghosted picture.However, digital television is able to overcome this shortcoming which plagues analog television. With digital television, distance does not matter. No matter how far the broadcast station is from the receiver, the picture quality does not diminish. As long as the digital signal is still being received, the picture quality remains the same. Digital television does not suffer from ghosting or noise that arises from weak sig nals. The converter boxes which are used by digital tuners receive numeric information from the antenna. This eliminates the possibility of interference in digital signals.Analog television signals are transmitted using and interlaced format. In this interlaced format, the odd number lines are transmitted first before the even number lines. Each of these sets of lines are referred to as fields. These two fields make up one picture frame, i. e. the video image. In a sense, analog television is restrictive. On the other hand digital television provides an opportunity for datacasting which enhances interactivity. In this modern age there is need to establish a two way relationship with the audience and this is what digital television ensures.The era of delayed feedback is no longer the case. Audience reaction can be measured with ease. However, it is important to state that analog television has been used before the advent of digital television. Although the former has its shortcomings it has served many uses in society to date. In the early days, according to American television standards, there the analog television was operated at 30Hz frames per second. This was in contrast to the 24 frames per second in the early days of motion pictures. However, with the introduction of color television there was a slight adjustment to 29. 97Hz frames per second.

The Moral Heroism Of Antigone By Susan B. Anthony

Humans are born with the potential to achieve greatness and to create a difference in the world. Though individuals possess the capacity to prove the immorality within them, they also possess an inner hero that is capable of performing tremendous good for the benefit of others. However, seldom do humans actually embrace the courage to stand up for their ethical principles and to challenge the existing social standards that are organized under strict leadership. Famous figures—from Susan B. Anthony to Rosa Parks—drew their moral heroism from the heroic action of characters in Greek literature such as Sophocles’s Antigone. The protagonist, Antigone, creates a conflict between her allegiances to political law and morals when the Theban king Creon decrees that the body of his nephew, Polyneices, remains unburied. To Creon, it sets a substandard example for the future of Thebes because Polyneices attacked his native city in a battle against the invading army of Argos. Since the morals of Antigone have a close connection with true justice and human well-being, she defies Creon’s laws and vows to give the proper burial rites to Polyneices as they were presented to her brother Eteocles. Antigone’s sacrifice to bury her brother results from a need to embrace family pride, a feeling to satisfy the gods’ desires, and a responsibility to represent the Theban citizens. The honor that Antigone wants to maintain for her family, coupled with the irreplaceable nature of family, outweigh her

Essay on Defences for Murder - 601 Words

Defences for Murder There are only three partial defences for murder; suicide pact, provocation-the loss of self control and reaction must be instantaneous and diminished responsibility. Amongst the three mentioned two are most frequently used, these are provocation and diminished responsibility, and only one full defence, self defence. These defences are used to reduce the sentence charge by the defendant to manslaughter from murder. In the following text I will be examining how men use provocation and diminished responsibility to walk free from murder. I will analyse the advantages and disadvantages of these defences and any alternatives or reforms. Firstly, provocation is seen by men†¦show more content†¦The law today is far too lenient upon men who abuse and kill their wives and claim ‘provocation’ to lessen the charge. Women are constantly beaten by their partners and some kept prisoners in their own home and eventually killed. In the case R.v.Thornton the defendant was a battered wife who killed her husband. Her husband after threatening her, the husband fell asleep, she went to the kitchen and returned with a knife stabbing him while he was asleep. Any sane person would say that she would have never taken her husband on if he were conscious, and if he were, she would have been killed not him. In the case R.v.Wilkinson the defendant had suffocated his wife in front of his four children because she was seeing another man, the defendant claimed provocation and he is currently serving 4 years. We can see from this that the system is unbalanced; it is in the favour of men and degrades the women. In the eyes of many these two defences are the focal point of the English legal system regarding murder, theft, assault etc. These defences can vary the sentence due to the severity of the actions and under what circumstances the crime was committed. If a women, for example, is being beaten constantly by her husband and is imprisoned in the house, and then suddenly lashes out at him and kills him,Show MoreRelatedMurder/Voluntary Manslaughter Criticisms and Reforms1472 Words   |  6 Pagesanswer Murder/Voluntary manslaughter criticisms and reforms Question Discuss the criticisms which may be made on the law on murder (including voluntary manslaughter) Suggested answer It is difficult to divorce criticism of the law on murder without also considering the relevant partial defences under the Homicide Act 1957.

ACS for Blind or Visually Impaired Clients- myassignmenthelp.com

Question: Discuss about theACS for Blind or Visually Impaired Clients. Answer: For Blind or Visually Impaired Clients For the blind or visually impaired to be able to operate a computer, they need to perform input/output operations. While using a pointing device is impossible, a program should be designed to accommodate the user to perform Input operations. Therefore, it is critical for the program to include tools that will replace the pointing device with the keyboard as the only input device. A screen reader is essential as it allows the program to read text on the screen and output it as sound. Additionally, for images, there is an algorithm that scans an image and converts grayscale images into musical soundscapes(Sumner, 2014). For employees and students, keyboards should have a nib on the letters F and J that will guide the fingers during typing. Also, common commands should be automated to ease accessibility and reduce repetition. Clients with Limited or Poor Hand Coordination Clients with limited or poor hand coordination may encounter problem in performing normal twists and turns responsible for operating a computer. Therefore, it is critical that the program includes features that will allow the user to basic computer I/O operation with limited mobility. Incorporation of onscreen keyboard allows the use of a joystick or a tracking ball to press keys on the onscreen keyboard image. Additionally, use of an autocorrect feature will help a person with poor hand mobility to type unique letters that represent a word or a block of text( Vanderheiden, G., Vanderheiden K., 1992).

Switched Networks Essay Example For Students

Switched Networks Essay Switched NetworksNetworks are getting more and more popular,and because of this more people use them, which slows them down. Networks in the future will need to have enough bandwidth to support applications,like multimedia, witch require larger bandwidth. Switching will changethe way networks are designed. These changes will maximize productivity. Switching technology is increasingthe efficiency and speed of networks. This technology is making currentsystems more powerful. Many networks are experiencing bandwidth shortages. We will write a custom essay on Switched Networks specifically for you for only $16.38 $13.9/page Order now There are several reasons for this including: an increase in traffic, becausenetworks have so many users, Amount of data between client/server applications,and the inefficient traffic patterns of most networks. Switching directs network trafficin a very efficient manner. It sends information directly from theport of origin directly to its destination port. Switching increasesnetwork performance, enhances flexibility and eases moves, add-ons andchanges. One of the benefits of switching is that it maintains adirect line of communication between two ports, and maintains multiplesimultaneous links between various ports. It reduces network trafficby reducing media sharing. This technology has some benefits overethernet routed networks. First, a 10 Mbps or 100 Mbps shared media canbe changed to 10 Mbps or 100 Mbps of dedicated bandwidth. Routers havemany devices attached to their ports, sharing the bandwidth. Switches letyou to connect either a shared segment of bandwidth (workgroup) or a dedicatedone (server) to each port. Second, this can be done without changing anysoftware or hardware already on the workstations Finally, a switch installationis less complex than a bridge/router configuration. A ethernet LAN runs at 10 Mbps. Stationsattach through a hub or repeater. Every station can receive transmissionsfrom all of the stations, but only in a half-duplex. This means that stationscannot send and receive data simultaneously. In a ethernet network onlyone packet can transmit at one time, this is what slows down networks. The bridge, the router and the switch, all attempt to reduce transmissiontime to increase performance. A two-port bridge splits a network intotwo physical segments and only lets a transmission cross if its destinationis on the other side. It also will only move a packet to the other sideif it is necessary. This reduces network traffic because trafficon one side stays local. Routers link multiple networks together. It maintains the flow of traffic and routes data to the network that itmust go to. (Each port has a unique network number.) it also has a firewallfunction. Bridges and routers have similar bus architectures. Switcheseliminate the bus architecture. Ethernet switches segment a LAN into manydedicated lines. A switch port may be configured in segments with manystations hooked to it or with a single station hooked to it. The rule isthat only one conversation may originate from any port at a time, it doesntmatter if there is one or a lot of stations connected to that port. Allports have to listen before they transmit. When a single LAN station isconnected to a switched port it is in full-duplex mode. This helpsbecause there are no collisions of packets since they are all separateports. Full-duplex switching means traffic can be sent and received atthe same time. Ethernet networks go from 100 Mbps to 200 Mbps. (hubs betweena workgroup and a switch will not run full-duplex, the workgroup is unswitchedethernet.). Switches are starting to be more popular than routersand bridges. Switches now do the segmentation once done by routers andbridges. Switches can do more than put a packet to one side or the other they send traffic right to its destination. .ua99744870e6a658f1908b214b4b378d8 , .ua99744870e6a658f1908b214b4b378d8 .postImageUrl , .ua99744870e6a658f1908b214b4b378d8 .centered-text-area { min-height: 80px; position: relative; } .ua99744870e6a658f1908b214b4b378d8 , .ua99744870e6a658f1908b214b4b378d8:hover , .ua99744870e6a658f1908b214b4b378d8:visited , .ua99744870e6a658f1908b214b4b378d8:active { border:0!important; } .ua99744870e6a658f1908b214b4b378d8 .clearfix:after { content: ""; display: table; clear: both; } .ua99744870e6a658f1908b214b4b378d8 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .ua99744870e6a658f1908b214b4b378d8:active , .ua99744870e6a658f1908b214b4b378d8:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .ua99744870e6a658f1908b214b4b378d8 .centered-text-area { width: 100%; position: relative ; } .ua99744870e6a658f1908b214b4b378d8 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .ua99744870e6a658f1908b214b4b378d8 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .ua99744870e6a658f1908b214b4b378d8 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .ua99744870e6a658f1908b214b4b378d8:hover .ctaButton { background-color: #34495E!important; } .ua99744870e6a658f1908b214b4b378d8 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .ua99744870e6a658f1908b214b4b378d8 .ua99744870e6a658f1908b214b4b378d8-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .ua99744870e6a658f1908b214b4b378d8:after { content: ""; display: block; clear: both; } READ: Changes in Germany - 1933-1939 EssayRISC (Reduced Instruction Set Computer)is a type of CPU to process in switches. It is used for general,or simple task, RISC switches are not as well at performing specific tasks. One of the advantages of RISC is that itis inexpensive compared to one with customized CPU. RISCs are already somewhatcommon in businesses and are off-the-shelf processors. This typeof switch can perform some functions similar to a router. The downsideof this type of RISC is that it is a store-and-forward processor that isnot as fast as an ASIC switch. ASIC (Application Specific IntegratedCircuit) This is the other design widely used in switches to process. Theyare custom designed to handle specific operations, all of the functionsare in hardware. If any changes are needed, manufacturing must be doneto rework hardware. No software upgrades are available. Another type of network architecture thatis benefiting from switching is, token ring. One of the advantagesis ? faster and larger networks. Since switches do all of the workthat routers and bridges do, and are deticated, it makes since that companiesare using more and more switches in a token ring network. There isanother technology that is starting to get more popular than ethernet ortoken ring, it is called ATM. Asynchronous Transfer Mode (ATM), is sometimescalled technology of the future, but it is being used today. A major plusof ATM is that it is the first technology that can deliver different typesof traffic, such as voice, video and data, over a single digital line. ATM can also handle scaleable amounts of bandwidth, as a result of itsswitching architecture, which can support multimedia applications and networkgrowth for years. Within the last year or so, ATM is getting more and morepopular with businesses, and companies are now have test networks of alltypes. Many have begun the transition to ATM networks, while others arewaiting for technical committees to finalize ATM standards that will addfeatures and flexibility for their networks. Companies are trying to understandATM technology and how it will effect their business. They are aware thatthe cost of ATM products has fallen dramatically in the last year. ATMsslightly higher cost over shared networks (Ethernet, Token Ring.),is justified by three times the performance. This access allows for moreproductivity in the workplace. With a business wanting more and morespeed and reliability there will be and is new technology coming out everyday. It is important for telecommunications professionals, and businessesto understand what exactly the new technology will do to help improve profit.
