Breadth-First Search (BFS) is widely used in real-world applications including computational biology, social networks, and electronic design automation. The most effective BFS approach has been shown to be a combination of top-down and bottom-up approaches. Such hybrid techniques need to identify a switching point which is conventionally found through expensive trial-and-error and exhaustive se...

Much research in recent years has focused on various routing strategies for supporting ee-cient communication in point-to-point networks. Other research has emphasized novel switching techniques, such as virtual cut-through and wormhole switching. However, little attention has been paid to the subtle interplay between routing and switching schemes. It is desirable to select routing strategies t...

First of all, in this paper, the topology and operation of the three-phase three-level Z-source inverter based on neutral-point-clamped (Z-NPC) are studied. Moreover, different combinations of permissible switching states and control signals are explained for this inverter. In this paper, the topology of the three-phase three-level Z-NPC inverter is extended for an n-level state. Also, a combin...

In this paper we are going to investigate the non-blocking operation of multirate log2(N; m; p) switching networks with multicast connections. The nonblocking operation of multi-log2N switching networks for point-to-point connections was firstly considered in [5, 6]. Conditions under which these switching networks are nonblocking for multicast connections were proposed by Tscha and Lea [7] and ...

The aim of the paper is to design a soft Switching Boost Converter with simulation of Maximum Power point tracking for Solar Home Lighting System. A 37Wp Solar Panel is used for designing the boost Converter using soft switching technique. Microcontroller Atmega32 is used to generate the necessary PWM switching signal for the MOSFETs. Soft-switching boost converter is designed to improve the ef...

This paper presents a novel three-point modulation technique for fractional-N frequency synthesizer applications. Convention modulated fractional-N frequency synthesizers suffer from quantization noise, which degrades not only the phase noise performance but also the modulation quality. To solve this problem, this work proposes a three-point modulation technique, which not only cancels the quan...

Improved switching characteristics were obtained from high-κ oxides AlOx, GdOx, HfOx, and TaOx in IrOx/high-κx/W structures because of a layer that formed at the IrOx/high-κx interface under external positive bias. The surface roughness and morphology of the bottom electrode in these devices were observed by atomic force microscopy. Device size was investigated using high-resolution transmissio...
