Multi-threading is a form of parallel processing in which the processor contains several independent contexts which share a single execution pipeline. We propose a new multi-threaded architecture which differs from previous architectures in that context switches are performed only when the running program cannot execute an instruction in the next cycle. We argue that this strategy can improve p...

The extra degree of freedom offered in hybrid electric vehicles have inspired many researchers to formulate and solve optimal control problems of various kinds. This paper presents an Approximate Dynamic Programming scheme that efficiently solves the optimal power split between the internal combustion engine and the electric machine in parallel hybrid powertrains. Gear switches and switches bet...

A novel two-switch high-step-up isolated converter with voltage lift is proposed in this paper. The proposed isolated converter utilizes a transformer with low turn ratio to achieve high step-up gain. The secondary winding charges two boosting capacitors in parallel as switches during the switch-on period, and two boosting capacitors are discharged in series during switch-off period. Thus, the ...

Switched networks are receiving much attention and supplying a major class of interconnect networks. This paper discusses major issues in switch design and switch interconnects. Due to the importance of high-speed switches in building switched LANs, major design issues are studied and several commercial switches are reviewed. Among different techniques used in switch design, cut-through switchi...

This paper proposes an alternative architecture for the implementation of Software Defined Radio (SDR) systems, providing low-cost, high degree of flexibility and scalability. The architecture is based on a cluster of COTS (Commercial Off-The-Shelf) computers interconnected by standard network devices (LAN network interface cards and switches). This architecture is mainly intended for testing s...

Nanoelectromechanical devices exhibiting dramatically improved robustness through novel material selection are demonstrated. A unique combination of carbon nanotube active elements and conductive diamond-like carbon contact electrodes results in reliable switching performance not found in devices with ubiquitously-used metal thin film electrodes. This in turn represents a viable means to improv...

Output queued switches are appealing because they have better latency and throughput than input queued switches. However, they are difficult to build: a direct implementation of an N × N output-queued switch requires the switching fabric and the packet memories at the outputs to run at N times the line rate. Attempts have been made to implement output queuing with slow components, e.g., by havi...

This paper provides a method for analyzing the queueing behavior of switching net works constructed from switches that employ shared bu ering or parallel bypass input bu er ing It extends the queueing models rst intro duced by Jenq and later generalized by Szyman ski and Shaikh to handle these classes of networks Our analysis explicitly models the state of an en tire switch and infers informati...

Particle accelerators usually require high voltage and high power. Typically, the high voltage/power generation utilizes a topology with an energy store and switching mechanisms to extract that stored energy. The switches may be active or passive devices. Active switches are hard or soft vacuum tubes, or semiconductors. When required voltages exceed tens of kilovolts, numerous semiconductors ar...

Many people are now engaged in remote conversations for a wide variety of scenes such as interviewing, counseling, and consulting, but there is limited number skilled experts. We propose novel framework parallel with semi-autonomous avatars, where one operator collaborates several robots or agents simultaneously. The autonomous dialogue system mostly manages the conversation, switches to human ...
