To extend the usefulness of rod bipolar cells for studies of chemical synaptic transmission, we have performed electrophysiological recordings from rod bipolar axon terminals in an in vitro slice preparation of the rat retina. Whole cell recordings from axon terminals and cell bodies were used to investigate the passive membrane properties of rod bipolar cells and analyzed with a two-compartmen...

This paper reports an algorithm for forming groups of students with regard to a computer system for collaborative learning designed to give a cue for debate utilizing mobile terminals. With this system, questionnaires which should be used as the seeds for debates are prepared in advance on the Web and all students attending the class answer to the questionnaires on the Web through their mobile ...

I n recent years, the number of intelligent workstations in use throughout the world has grown at an ever-increasing rate. This fact is also true at the Thomas J. Watson Research Center, a major research facility of IBM. For many years, the Watson Research Center has been at the leading edge in the use of interactive computer systems (containing a very large computing facility and actually havi...

OBJECTIVE: To examine the scientific data in the literature regarding eye problems and possible damage during the use of computer video display terminals. DATA SOURCES: Medline and non-Medline literature search and personal experience. STUDY SELECTION: Studies that provided evidence-based information about eye damage and eye care during the use of video display terminals were selected. DATA EXT...

Despite all the attempts of modern information technology to supplant paper by sophisticated electronic devices, paper is still omnipresent in virtually any office environment. We have learned over the last decade that paper is an indispensable part of our daily work and that even the latest computers are not able to mimic its functionality. Today, paper and computer are coexisting side by side...

This paper addresses the applications of different techniques for solving container terminals problems. We have built a simulation model that can be used to analyze the performance of container terminal operations. The proposed approach is intended to be applied for a real case study in Alexandria Container Terminal (ACT) at Alexandria port. The implementation of our approach shows that a propo...

This paper presents NetICE, Networked Intelligent Collaborative Environment, which is a prototype designated to provide an immersive environment to allow people to communicate from anywhere at any time. The NetICE system consists of two components: an intelligent network and smart terminals. The intelligent network allows multiple users to be connected to the same virtual space. The smart termi...

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 ...
