The authors developed this remote experiment with the objective to study the Hooke＇s law through the analysis of the coil spring. The remote experiment is available in a website, where the students can manipulate and observe the educational press and confirm Hooke＇s statements with the output information. In addition, the students will have the opportunity to read in the website about the educational press, the physical law, and the use of the press in industrial processes. This remote experimentation exerts a force in the mechanical spring creating a deformation. In the defined point, the microcomputer will collect the data from the sensors, and it will save this data in the database. After the process execution, a graph with the data will be plotted in the website. The tests confirm that the educational press has informational potential because it returned values consistent with Hooke＇s law and the experiment presented repetition in all tests realized.展开更多

Problematising the genesis of the Korean Wave in Taiwan, the paper proposes to see it as the product of social and political forces pertaining to a specific moment of history of Taiwan. Other than deeming the genesis categorically as a cultural instance, it argues that the Wave is in effect the production manufactured at the convergence of social political changes at a historical moment unprecedented in Taiwan history. To respond to the new social and political conditions, the Korean Wave is deliberately appropriated as the extension of social institution and political control for the purpose of prolonging class interests of the traditional rulers. By means of mammoth circulation and transmission of print media and television broadcast, the Wave is immediately called into being and captivates a throng of Taiwan Residents audience. In return, the overwhelming popularity of Korean TV dramas is capitalized on politically besides socially and culturally in order to meet new needs. Resiting the Korean Wave in Taiwan in the social and political processes at the specific moment of Taiwan history, its genesis is thereby complicated and overdetermined on top of the advanced and promised drama qualities and productions. Inevitably a limited view, however, the paper is hoped to provide an alternative aspect to the studies of the Korean Wave either in Taiwan or other regions.展开更多

To speed up the design further, a novel partial product compression circuit based on interleaved adders and a modified hybrid partial product reduction tree (PPRT) scheme are proposed. The MAC can perform 1-way 32-bit, 4-way 16-bit signed/unsigned multiply or multiply-accumulate operations and 2-way parallel multiply add (PMADD) operations at a high frequency of 1.25 GHz under worst-case conditions and 1.67 GHz under typical-case conditions, respectively. Compared with the MAC in 32-bit microprocessor without interlocked piped stages (MIPS), the proposed design shows a great advantage in speed. Moreover, an improvement of up to 32% in throughput is achieved. The MAC design has been fabricated with Taiwan Semiconductor Manufacturing Company (TSMC) 90-nm CMOS standard cell technology and has passed a functional test.展开更多
