The results of integrity narrowband and wideband lumped element circulators design methodology to the computer aided system microwave devices AWR Microwave Office are presented in article. calculation method narrow band circuits which consist serious shunt tuning capacities is investigated. simple visual ferrite isolators optimize based on circulation impedance described here. ultra circulator ...

The main objective of this work is to determine the reading performance of operators’ under different viewing angles of a desktop computer. The effects of text/background color, viewing distance and character size on the speed of reading were investigated. The text and/or the background color combination were varied, with constant luminance contrast. Performance was recorded in terms of words p...

We set up a Web Bulletin Board System 1 (BBS) in the U.S. in 2008 and in Japan in 2007 and experimented whether an incentive ∗Takuya Nakaizumi, Associate Professor, Kanto Gakuin University, and Visiting Scholar, UC San Diego International Relations and Pacific Studies, [email protected], Mitsuharu Watanabe, Professor, Kanto Gakuin University, [email protected] : 150-1 Mutsurahigashi, K...

The PLATO IV System based at the University of Illinois at Urbana is a highly sophisticated and very powerful approach to Computer Aided Instruction. The PLATO IV system makes use of a plasma display terminal that is a unique device with capabilities not presently found on computer terminals. A number of ARPA supported projects intend to use the plasma terminal on local connection to computer r...

This paper presents the dynamic reservation protocol for supporting variable-rate data services on time-division multiple-access based wireless networks. It allows a large number of data terminals to access data applications by sharing a reserved data-carrier. Through dynamic reservation data terminals can get their needed radio channels for uplink transmission without contention. The protocol ...

Modeling and simulation are essential tools for the design and analysis of container terminals. A computer model can emulate the activities at various levels of details and capture the essential interactions among the subsystems. Analysis based on the simulation is particularly useful for designing new terminals, making modifications to existing terminals, and evaluating the benefits of new res...
