        Fossil fuels environmental challenges and the role of solar photovoltaic technology advances in fast tracking hybrid renewable energy system

        Williams S. Ebhota,Tien-Chien Jen 한국정밀공학회 2020 International Journal of Precision Engineering and Vol.7 No.1

        The rise in global urbanization comes with sustainable development challenges, especially in lower-middle-income countries. In response to these urbanization and energy challenges, this study focuses on the roles of energy materials (EMs) advances on community-scale hybrid renewable energy systems (HRES). The study proposes the integration of energy material (EM) R&D into HRES (EMR&D-HRES). The study examines the economic benefits and the environmental and health consequences that trail the deployment of fossil fuels. Special attention was given to SSA, a region that—accommodates the highest population without modern energy; emits the least CO2 to the global CO2 emissions and yet endangered by climate change challenges and air pollution diseases. The study includes global responses to energy challenges, such as increase alternative energies share, with special attention to solar photovoltaic (PV) power generation technologies; policy framework; HRES and effects of PV materials advances on HRES. This study is of the view that a further breakthrough in the production of low-cost flexible thin film PV modules will facilitate energy trilemma accomplishment. The exploitation of the attributes of atomic layer deposition in manufacturing of thin film is seen as a potential future production technique, suitable for efficient flexible thin-film PV module production.

        The Role of a Public Speaking Course in the Training of Interpreters

        Williams, Neal 한국통번역교육학회 2009 통번역교육연구 Vol.7 No.2

        전문 통역사에 대한 수요는 확고부동하다. 이러한 수요에 부응하려면 통역사 훈련을 위한 커리큘럼 개발은 시급한 과제이다. 통역사 교육 프로그램은 일반적으로 전문 통역사를 위한 퍼블릭 스피킹 능력을 기본 요소로 간주한다. 따라서 퍼블릭 스피킹이 대부분의 커리큘럼에 포함되지만 구체적인 이론적 배경은 미흡한 측면이 있다. 이러한 맥락에서 본고는 통역사 교육에서 퍼블릭 스피킹을 포함하여야 하는 두 가지 이론적 근거를 제시한다. 첫째, 통역사는 기본적으로 퍼블릭 스피커이다. 비록 타인인 연사의 메시지를 전달하지만 통역사는 들리도록 말하기, 명료한 발음, 적절한 발화 속도 등 퍼블릭 스피킹의 필수 요소를 반드시 익혀야 한다. 따라서 퍼블릭 스피킹 기술은 선택이 아닌 필수이다. 둘째, 퍼블릭 스피킹 기술은 통역사의 경력 개발에 필수적이다. 경력 개발에는 타인과의 네트워크 구성이 필수이며, 퍼블릭 스피킹 기술은 네트워크 구성의 통합 요소이다. 성공적인 통역사는 네트워크 구성에 능하며 퍼블릭 스피킹에도 능하다.

        Exact calculation of natural frequencies of repetitive structures

        Williams, F.W.,Kennedy, D.,Wu, Gaofeng,Zhou, Jianqing Techno-Press 1996 Structural Engineering and Mechanics, An Int'l Jou Vol.4 No.5

        Finite element stiffness matrix methods are presented for finding natural frequencies (or buckling loads) and modes of repetitive structures. The usual approximate finite element formulations are included, but more relevantly they also permit the use of 'exact finite elements', which account for distributed mass exactly by solving appropriate differential equations. A transcendental eigenvalue problem results, for which all the natural frequencies are found with certainty. The calculations are performed for a single repeating portion of a rotationally or linearly (in one, two or three directions) repetitive structure. The emphasis is on rotational periodicity, for which principal advantages include: any repeating portions can be connected together, not just adjacent ones; nodes can lie on, and members along, the axis of rotational periodicity; complex arithmetic is used for brevity of presentation and speed of computation; two types of rotationally periodic substructures can be used in a multi-level manner; multi-level non-periodic substructuring is permitted within the repeating portions of parent rotationally periodic structures or substructures and; all the substructuring is exact, i.e., the same answers are obtained whether or not substructuring is used. Numerical results are given for a rotationally periodic structure by using exact finite elements and two levels of rotationally periodic substructures. The solution time is about 500 times faster than if none of the rotational periodicity had been used. The solution time would have been about ten times faster still if the software used had included all the substructuring features presented.

        동아시아 구법승과 상카시야 유적

        Williams Joanna G. 미술사와 시각문화학회 2005 미술사와 시각문화 Vol.4 No.-

        According to Legge, Faxian wrote: Proceeding 18 yojanas southeast [from Mathurii and 7 yojemas from Kanauj, which he visited next], they found themselves in a kingdom called Sankasya, at the place where the Buddha came down, after ascending to the Trayatrimsa heaven… The bbirsuni Utpalavarna thought in her heart, "Today the kings ... will all be meeting the Buddha. I am but a woman; how shall I succeed in being the first to see him?" Buddha immediately ... changed her into the appearance of a holy cakravartin king, and she was foremost of all in doing reverence to rum. As Buddha descended from his position aloft in the Trayatrimsa heaven, when he was coming down, there were made to appear three flights of precious steps. Buddha was on the middle. composed of the seven precious substances. The king of Brahma-loka also made a flight of silver steps appear on the right side, where he attended with a white chowry in his hand, Sakra, ruler of devas, made steps of purple gold on the left, where he held an umbrella "" When he was come down, the three flights all disappeared in the ground, excepting seven steps ... Afterwards King Asoka, wishing to know where their ends rested, sent men to dig and see, They went down to the yellow springs [the water table] without reaching the bonom of the steps, and from this the king rceived an increase to his reverence"" [Asoka] built a vihara over the steps, with a standing image 16 cubits in height, right over the middle flight. Behind the pillar, he erected a stone pillar, about 50 cubits high, with a lion on the top of it. Let into the pillar, on each of its 4 sides, there is an image of the Buddha, inside and out shining and transparent, and pure as it were of lapis lazuli [which roared in a later monastic debate], Faxian also reported stupas built later where the nun Utpalavarla knelt, where the Buddha cut his hair, where three previous Buddhas sat, as well as offerings made to a white-eared dragon that continued to protect the monastic community, One gets the impression of a crowded, complex site in the early 5th century, with presumably wooden monastic buildings, Over 200 years later, Xuanzang described visiting the site of the descent from Tryatrima named now)iebita (Beal: "written formerly Sengjiashe") and located less than 200 li southeast from Kanauj (in which Beal suggests he is mistaken on the direction), His account reads: Some centuries ago the ladders still existed in their original position, but now they have sunk into the earth and have disappeared. The neighboring princes ... bujlt up of bricks and chased stones, on the ancient foundations 3 ladders resembling the old ones. They are about 70 feet high. Above them they have built a vihara in which is a stone image of Buddha, and on either side of this is a ladder of Brahma and Sma, just as they appeared. On the outside of the vihara, but close by its side, there is a stone column about 70 feet high, which was erected by Asoka-raja, It is of a purple color, and shining as if with moisture. The substance is hard and fmely grained, Above it is a lion sitting on its haunches and facing the ladder. There are carved fig-ures inlaid, of wonderful execution on the four sides of the pillar and around It Xuanzang also records other stupas commemorating Buddhas of the past and the nun Utpalavatma, now eclipsed by Subhoti who had already seen the dharmakaya in the form of the doctrine that all existing things are void of reality, Again, we get a picture of a bustling monastic community in the 7th century. And the resplendent lion pillar with Buddha images stands out in both accounts, On the basis of the name Sankasya, known from the pilgrims and from texts like the Divyavadana, as well as the general location, Cunning-ham identified the modern village Sankfsa in modern Farrukhabad district, up. with the site of the Descent, It lies some 40 km. northeast of Kanauj in the Doab, richly populated with ancient remains, The two Gupta sites Jankhat and Bilsadh took me to this area in 1974, Cunningham included the site in his reports for 1862 and 1876. In the first he recorded the presence of an ASokan capital and worship of a naga named Karewar, which he identified with Faxian's description. In 1876 hecollected objects reproduced on the right. I know these only from this abysmal image and would be delighted to hear that they survive in some museum. Cunningham suggested that #2, a fragment of a tiny soapstone disc, represented the site itself, with a seated Buddha and kneeling Utpalavarna at the top of what survived. The Archaeological Survey of India returned to this site ten years ago and excavated here for at least 2 seasons, as reported in Indian Arcbaeolo-gy, A Review for 1995-96 and 96-97, finding Painted Grey Ware, Northern Black Polished Ware, Sunga, Kushan, and Gupta pottery, pre-Kushan bricks, and terra-conas attributed to the Gupta period, The Aokan capital found here has continued to receive attention. Is this what both Faxian and Xuanzang described as a lion? Cunningham asserted that both were mistaken about the identity of the animal, It might be pointed out that the shorter pillar that stands at the site of the Parinilvana makes some confusion plausible, Xuanzang describes the pillar standing at Sarnath as "bright and shining as a mirror: its surface is glistening and smooth as ice, and on it can be constantly seen the figure of Buddha as a shadow," I. e" he ignored the form of the capital and was mesmerized by the stone's polish, It is also possible that the Buddha figures he mentions here and Sa:nkasya were in fact carved on the pillar like the Gupta pillar at Kahaum, which has four TIrthankaras at the top as well as a single one below. The elephant capital has continued to attract attention for the excep-tional swirls beneath what was long considered a lotiform bottom to the capital, John l1win took these to indicate that the "lotus" in fact originated as a piece of cloth draped over a wood
