This paper presents recent progress made in the development of an optical packet and circuit integrated network. From the viewpoint of end users, this is a single network that provides both high-speed, inexpensive services and deterministic-delay, low-data-loss services according to the users’ usage scenario. From the viewpoint of network service providers, this network provides large switching...

High-voltage circuit breakers are among the most important equipments for ensuring the efficient and safe operation of an electric power system. On occasion, circuit breaker operators may wish to check whether equipment is performing satisfactorily and whether controlled switching systems are producing reliable and repeatable stress control. Monitoring of voltage and current waveforms during sw...

This paper studies the one-to-all broadcast in a circuit-switched 2D torus of any size with-port capability. This is a generalization of the one-port and all-port models. Existing results, as compared to ours, can only solve very restricted sizes of tori, and use more numbers of steps. 1 Introduction One primary communication in an interconnection network is the one-to-all broadcast, where a so...

This paper is a study of one-to-all and all-to-all data movement patterns on cycles, tori, and multidimensional tori that use synchronous circuit-switched routing with virtual channels. The data movement patterns that we study are broadcasting, scattering, gossiping, and multi-scattering. We present new circuit-switching algon’thms for all of these patterns for cycles, two-dimensional tori, and...

ion (with a SQL-like language) is too high-level; how would languages like Erlang fit into this project? In fact, the authors really thought about using a functional language instead of a custom DSL. Someone asked whether they could still run into inconsistencies between layers. Tim replied that they don’t allow state to expire due to lack of use. They are adding the ability to have timeout eve...

In this paper a new 8-bit 50-Msample/s CMOS digital-to-analog converter (DAC) is presented. The circuit employs 9 operational transconductance amplifiers (OTAs) and CMOS transistors as switching circuit. The proposed DAC is simulated using SPICE simulation program with 3μm CMOS technology. Simulation results shows verify good performance of the circuit.

Novel 3-level GTO inverter topology is presented. This new power circuit includes many advantages comparing with the conventional 3-level GTO inverter. The main advantages are snubberless and good device utilization by employing dual quasi-resonant dc-link which guarantees the complete zero voltage switching of the inverter GTO's. This 3-level GTO inverter can be operated with lower switching l...

|We consider optical networks using wavelength division multiplexing, where the path a signal takes is determined by the network switches, the wavelength of the signal, and the location the signal originated. Therefore, a signal is routed through a combination of circuit switching and wavelength routing (assigning it a wavelength). We present a bound on the minimum number of wavelengths needed ...

This paper summarizes recently developed soft-switching inverters and proposes two alternative options for electric propulsion drives. The newly developed soft-switching inverter employs an auxiliary switch and a resonant inductor per phase to produce a zero voltage across the main switch so that the main switch can turn on at the zero-voltage condition. Both the auxiliary switch and the resona...

Circuit switching, suited to providing real-time services due to the low and fixed switching delay, is not cost effective for building integrated services networks because is based on static allocation of resources which is not efficient with bursty data traffic. Moreover it cannot handle flow that are not integer multiple of 64 Kb/s, preventing the usage of low bit rate codecs. This work explo...
