Tele Education 1.0 INTRODUCTION 1.1 Background of Tele-education Tele-education has a long history beginning with systems like that for teaching children in Australian Outback, the British Open University and other such organizations. These built on the idea of correspondence courses where course materials are sent periodically by post and augmented the experience with broadcasts either on radio or on TV. The problem of student isolation was addressed partially through techniques such as telephone access or two-way radio links with teachers. At the end of 1980s, the vest majority of distance education throughout the worlds was still primarily print-based. Technologies used for distance education are evolving from primarily ?one-way' technologies and applications such as computer aided learning, computer based training and computer aided instruction, to more ?two-way' technologies and applications such as computer mediated communications and computer conferencing systems for education. The significance of ?two-way' technologies is that they allow foe interaction between participant and tutors, and perhaps even more significantly amongst participant themselves. This development has allowed and in some senses force researches to look more closely at the impact of educational environment, on the students learning experience. In the future, it is expected that the telecommunications-based technologies to become the primary means of delivery of distance teaching. The reasons for this are as follows: a much wider range of technologies are becoming more accessible to potential distance education participants the costs of technological delivery are dropping dramatically the technology is becoming easier to use for both tutors and learners the technology is becoming more powerful pedagogically education centers will find it increasingly difficult to resist the political and social pressures of the technological imperatives. 1.2 The Emergence of Tele-education Radical changes in the computing infrastructure, spurred by multimedia computing and communication, will do more than extend the educational system, that is revolutionize it. Technological advances will make classrooms mush more accessible and effective. Today, classroom education dominates instruction from elementary school to graduate school. This method has remained popular for a very long time and will probably persist as the most common mode of education. However, classroom education has its problems, that is the effectiveness decline with increase in the number of students per class. Other pressures affect the instructors, many of whom are not experts in the material they must teach, are not good ?performers' in class, or simply are not interested in teaching. The biggest limitation of the classroom instruction is that a class meets at a particular time in a particular place. This essentially requires all students and the instructors to collect in one spot for their specified period. But with the emerging technology, these problems can be overcome. 1.3 Reasons for studying Tele-education The current Tele-education systems that have been applied in some countries are generally of multipoint transmission technique. It is found that, this kind of transmission technique having several problems or defects. Mostly, problems raised during the application of the system. One of the significant problems raised is that, for the multipoint transmission, the signals or information transmitted by the sender do not completely received by the receiver. This problem is might be due to error that occurs during the transmission of the signals or information. Another problem is lag of transmission. For this case, the signals or information transmitted do not arrive at all the receiver at the same time, for example, the question raised by the lecturer might not received by the students at the same time and this is not a good environment for Tele-education system. Some receiver receives the signals earlier than the others and some later or even not receives at all. Therefore, it is important to study the Tele-education technology from time to time to overcome these problems so that the Tele-education system could provide a more effective way of learning environment. In order to have a lecture from, for example, a very famous professor from other country would require him to come at our place. But the amount of money spent for paying him to give lecture would be very expensive and this also would cause troublesome for him. However, this problem can be solved with Tele-education system in which the professor does not need to go anywhere else to give his lecture. This would save a lot of expenses and time. Another reason is that, in normal classes the learning process would not be very effective if the number of students in a class is very big. This is because the lecturer alone can not coordinate such a large class. With Tele-education system, one lecturer could deliver

Ovids Account of Aphrodite and Adonis

Ovid's Account of Aphrodite and Adonis The love goddess of the Greeks, Aphrodite, usually made other people fall in love (or lust, more often than not), but sometimes she, too, was smitten. In this story of Adonis and Aphrodite, which comes from the tenth book of, the Roman poet Ovid summarizes Aphrodites ill-fated love affair with Adonis. Aphrodite fell in love with lots of males. The hunter Adonis was one of these. It was his good looks that attracted the goddess and now the very name Adonis is synonymous with male beauty. Ovid says that by Aphrodites falling in love with him, the mortal Adonis avenged the incest between his parent Myrrha and her father Cinyras and then he caused Aphrodite intolerable grief when he was killed. The original act of incest was provoked by unquenchable lust caused by Aphrodite. Note the geographic locations of cult sites that Aphrodite is accused of neglecting: Paphos, Cythera, Cnidos, and Amathus. Also, note the detail of Aphrodite flying with swans. Since this is part of the work on physical transformations by Ovid, the dead Adonis is turned into something else, a flower. Also worth noting: Homeric Hymn to Aphrodite V. This hymn tells the story of Aphrodites love affair with the mortal Anchises.Aspects of Venus (Aphrodite) Ovids Story The following is Arthur Goldings translation from 1922 of the section of the tenth book of Ovids Metamorphoses on the love story of Adonis and Aphrodite: That son of sister and grandfather, whowas lately hidden in his parent tree,just lately born, a lovely baby boyis now a youth, now man more beautiful825 than during growth. He wins the love of Venusand so avenges his own mothers passion.For while the goddess son with quiver heldon the shoulder, once was kissing his loved mother,it chanced unwittingly he grazed her breast830 with a projecting arrow. Instantlythe wounded goddess pushed her son away;but the scratch had pierced her deeper than she thoughtand even Venus was at first deceived.Delighted with the beauty of the youth,835 she does not think of her Cytherian shoresand does not care for Paphos, which is girtby the deep sea, nor Cnidos, haunts of fish,nor Amathus far-famed for precious ores.Venus, neglecting heaven, prefers Adonis840 to heaven, and so she holds close to his waysas his companion, and forgets to restat noon-day in the shade, neglecting the careof her sweet beauty. She goes through the woods,and over mountain ridges and wild fields,845 rocky and thorn-set, bare to her white kneesafter Dianas manner. And she cheersthe hounds, intent to hunt for harmless prey,such as the leaping hare, or the wild stag,high-crowned with branching antlers, or the doe.850 she keeps away from fierce wild boars, awayfrom ravenous wolves; and she avoids the bearsof frightful claws, and lions glutted withthe blood of slaughtered cattle.She warns you,855 Adonis, to beware and fear them. If her fearsfor you were only heeded! Oh be brave,she says, against those timid animalswhich fly from you; but courage is not safeagainst the bold. Dear boy, do not be rash,860 do not attack the wild beasts which are armedby nature, lest your glory may cost megreat sorrow. Neither youth nor beauty northe deeds which have moved Venus have effecton lions, bristling boars, and on the eyes865 and tempers of wild beasts. Boars have the forceof lightning in their curved tusks, and the rageof tawny lions is unlimited.I fear and hate them all.Wh en he inquires870 the reason, she says: I will tell it; youwill be surprised to learn the bad resultcaused by an ancient crime. But I am wearywith unaccustomed toil; and see! a poplarconvenient offers a delightful shade875 and this lawn gives a good couch. Let us restourselves here on the grass. So saying, shereclined upon the turf and, pillowingher head against his breast and mingling kisseswith her words, she told him the following tale: Story of Atalanta My dear Adonis keep away from allsuch savage animals; avoid all thosewhich do not turn their fearful backs in flightbut offer their bold breasts to your attack,1115 lest courage should be fatal to us both.Indeed she warned him. Harnessing her swans,she traveled swiftly through the yielding air;but his rash courage would not heed the advice.By chance his dogs, which followed a sure track,1120 aroused a wild boar from his hiding place;and, as he rushed out from his forest lair,Adonis pierced him with a glancing stroke.Infuriate, the fierce boars curved snoutfirst struck the spear-shaft from his bleeding side;1125 and, while the trembling youth was seeking whereto find a safe retreat, the savage beastraced after him, until at last, he sankhis deadly tusk deep in Adonis groin;and stretched him dying on the yellow sand.1130 And now sweet Aphrodite, borne through airin her light chariot, had not yet arrivedat Cyprus, on the wings of her white swans.Afar she recognized his dying groans,and turned her white birds towards the sound. And when1135 down looking from the lofty sky, she sawhim nearly dead, his body bathed in blood,she leaped downtore her garmenttore her hair and beat her bosom with distracted hands.And blaming Fate said, But not everything1140 is at the mercy of your cruel power.My sorrow for Adonis will remain,enduring as a lasting monument.Each passing year the memory of his deathshall cause an imitation of my grief.1145 Your blood, Adonis, will become a flowerperennial. Was it not allowed to youPersephone, to transform Menthes limbsinto sweet fragrant mint? And can this changeof my loved hero be denied to me?1150 Her grief declared, she sprinkled his blood withsweet-smelling nectar, and his blood as soonas touched by it began to effervesce,just as transparent bubbles always risein rainy weather. Nor was there a pause1155 more than an hour, when from Adonis, blood,exactly of its color, a loved flowersprang up, such as pomegranates give to us,small trees w hich later hide their seeds beneatha tough rind. But the joy it gives to man1160 is short-lived, for the winds which give the flowerits name, Anemone, shake it right down,because its slender hold, always so weak,lets it fall to the ground from its frail stem.

Microelectronics Writing - Assignment Example Its main purpose, in fact, does not differ much from the old cameras that actually use films instead of digital file storage media. The said media can either be a digital memory card or an internal storage that is built-in to the camera. Just like the old cameras, it is meant for capturing moments in pictures. One major innovation that is made possible with the use of microelectronics though, is that a digital camera could also take videos. The old analog ones have a functionality that is limited in taking only still pictures. The first digital camera model that was produced and sold in the market was the Dycam Model 1. It was sold only for a very short period, from 1990 until 1991. (Raskin) In order to retrieve the pictures taken and to print these in black and white, this camera had to be connected to a computer. This was soon followed by a long line of digital camera models from Kodak and Nikon. With the introduction of JPEG and MPEG formats for still pictures and videos respectiv ely, further developments in the digital camera were made. Nowadays, many digital cameras have more powerful lenses and better picture resolutions. More importantly, these have become much easier to operate. As the features and capabilities began to improve, these devices have also become more in demand. Only very few photographers have, in fact, continued to rely on the analog cameras. When a digital camera takes a picture, light is allowed to strike â€Å"a digital sensor array instead of a piece of film† in the case of an analog one. (Digital Darrel) This digital sensor is actually made of pixels, which are arrays of tiny sensor points. The image taken are then stored as millions of dots of lights or megapixels. The resolution of the picture or its sharpness depends on the amount of megapixels that the digital camera is capable of. The bigger the megapixels, the better the quality of the pictures the camera can produce. This goes the same for the videos made through the di gital camera. The images or videos are then recorded in the storage medium. This may be built-in memory chip of the camera or in an external device such as an SD card or an MMC. If the photographer wants to download the pictures to the computer or to have these printed, he may have to use a cable, which usually comes along with the camera when purchased. However, the latest digital camera models already have Bluetooth capabilities. With Bluetooth, the downloading and printing can be done even without the use of cables as long as the printer or the computer is also Bluetooth-enabled. The reason why many photographers find the digital camera a great choice for a gadget is that everything is automatic. A photographer can take more pictures in less time with a digital camera because he does not have to wait for one or a couple of seconds for any film to be ready. Aside from this, the latest models of this device actually have features that would make the photographer take better angles. In fact, these would also immediately adjust the distance without any prompting through its automated zooming system. Another important characteristic is that the digital images can be downloaded to a computer and can be subjected to editing with the use of the photo-editing software such as Photoshop and Corel. As a video recorder, a digital camera is definitely lighter and handier. However, it may have some limitations in taking videos when compared to the digital video
