A contention channel (C-channel) carriers the reservation broadcasts while a data channel (D-channel) delivers the transmitted data. Each D-channel transmission is restricted to a limited number of data packets so that no one station dominates the channel. Each station limits the number of unsuccessful attempts to transmit each C-channel request packet to 20. Data packets sent to each station for transmission are ranked according to their arrival time, with older data sent at higher priority. The performance of TCRN/PA is compared with that of CSMA-CD-based networks, such as SRMA and ring and polling networks, for identical system bandwidths and is found to give greater throughput, as well as shorter delay, particularly at high throughputs.<<ETX>>","PeriodicalId":201543,"journal":{"name":"[1990] Proceedings.

A simplified approach to studying the phenomenon of self-excitation in induction generators, based on the concept of static bifurcation and the q-d equivalent circuit equation in the synchronous reference frame, is proposed. This approach provides the necessary framework for identifying the boundary of possible self-excitation for a generalized load comprising both resistive and inductive loads. Example of these boundaries are shown. The limitation of capacitive self-excited induction generator operation has been determined, and suggestions as to how constant voltage and frequency power can be attained have been derived on the basis of the bifurcation fields. For the cases in which the reactive power is provided from a pulsewidth-modulated inverter, it has been shown how the switching frequency and the effective value of the inverter capacitance can be appropriately and structurally manipulated to obtain constant voltage and constant frequency power from the generator.<<ETX>>","PeriodicalId":201543,"journal":{"name":"[1990] Proceedings.

The prototype ASIC is currently being fabricated in 2.0- mu m CMOS technology and has been simulated at 20 MHz.

In the procedure, injected current at one of the logic gate's transistor drains increases the propagation delay of the logic gate. This occurs because increased current at the transistor drain decreases the rate of charge transfer between the logic gate and its output load. By use of an indirect measurement scheme, a curve depicting laser-induced propagation delay as a function of illumination is experimentally generated. This curve is then analyzed to determine whether or not the examined signal path has critical timing.<<ETX>>","PeriodicalId":201543,"journal":{"name":"[1990] Proceedings.

The integration of information from images from different types of sensors poses several interesting subproblems that are handled in a hierarchical manner.

Integration may take place at various levels, ranging from pixel level to logical concepts such as features, objects, and scenes.

The eigenvalues that contribute the most to the performance measure are identified as the critical modes.

The purpose of the paper is to reexamine some of the well known facts about nonlinear systems and their analysis. For nonlinear systems there may be two or more different steady-state responses, as in the case of jump resonance; there can be responses of different periods, as in the case of subharmonics; or there can be a nonperiodic response, as in the case of systems that exhibit chaos. This work deals with the application of iteration and Volterra series analysis methods to certain types of problems with interesting solutions. In particular, the jump resonance phenomenon and the initial conditions leading to different harmonic solutions are considered.<<ETX>>","PeriodicalId":201543,"journal":{"name":"[1990] Proceedings.
