In this paper, a voltage-boost-type non-voltage drop single-phase full-bridge inverter connected to switched-capacitor structure is proposed. The output voltage of the controlled by pulse width modulation DSP control lead and break active switches. switches work at low frequency; other high frequency. uses two capacitor modules charge discharge alternately so as overcome problem on side in tran...

— The need for better quality of service is growing as new quality sensitive services are becoming more and more important in data networks. The key element in providing quality-of-service or gradeof-service in packet networks is deciding when or in what order the incoming packets should depart the system. In other words the departing packets have to be somehow scheduled. Implementing this sche...

A parallel routing algorithm for controlling the class of interconnection networks called group connectors is presented. Given any legal mapping from input to output groups with busy inputs, this algorithm can determine the switch setting of a Benes group connector with inputs and output groups in time on a completely connected computer or the EREW PRAM model with processing elements. The imple...

In this paper we propose an enhanced parallel iterative scheduler for IBWR synchronous slotted OPS switches in SCWP mode. It obtains a maximal matching of packet demands without resource conflicts. The analytical and numerical results are highly competitive regarding previous work.

Floral scents are among the key signals used by pollinators to navigate to specific flowers. Thus, evolutionary changes in scents should have strong impacts on plant diversification, although scent-mediated plant speciation through pollinator shifts has rarely been demonstrated, despite being likely. To examine whether and how scent-mediated plant speciation may have occurred, we investigated t...

Modern switches have packet processing capacity of up to multi-tera bits per second, and they are also becoming more and more programmable. We seek to understand whether the programmability can translate packet processing capacity to computational power for parallel computing applications. In this paper, we first develop a simple mathematical model to understand the costs and overheads of data ...

This work analyzes whether a parallel packet switch (PPS) can emulate an output-queued (OQ) packet switch. The class of PPS is characterized by the deployment of parallel low-speed switches. Each lower speed packet switch operates at only a fraction of the input line rate R. This study develops and investigates a PPS which distributes cells to low-speed switches and uses outputs with push-in ar...

* This material is based upon work supported by the National Science Foundation under Grant No. 9875177. Abstract Input buffered switches with Virtual Output Queues (VOQ) are scalable to very high speeds, but require switch matrix scheduling algorithms to achieve high throughput. Existing scheduling algorithms based on parallel requestgrant-accept cycles cannot natively support variable length ...

Autonet is a self-configuring local area network composed of switches interconnected by 100 Mb/s, full-duplex, point-to-point links. The switches contain 12 ports that a re internally connected by a full crossbar. Switches use cut-through to achieve a packet forwarding latency as low as 2 ms/switch. Any switch port can be cabled to any other switch port o r to a host network controller. A proce...
