In this paper, a multiphase sliding mode (MPSM) control method with a master–slave structure is proposed and analyzed in order to suppress ripples at input terminals or output terminals in DC/DC converter applications. With the proposed MPSM, the switching frequency of a multiphase DC/DC converter does not need to be operating such a high switching frequency as adopted in a conventional sliding...

The purpose of this work is to determine the values electrical parameters synchronous and induction machines validate interactions between an generator a generator. generators are connected in two ways: (i) isolated from common bus (ii) parallel steady state, subject nonlinear load. They old refurbished machines; thus, parametric regression methodology used parameter values. After computational...

Recently, the development of technology has enriched form classroom interaction. Exploring characteristics current teaching interaction forms can clarify deficiencies interactions, thereby improving teaching. Based on existing interactive coding system, this paper adopted ITIAS and took with whiteboard, television or mobile terminals as research scene, selected 20 videos cases in environment ob...

Due to its simplicity, directness, and rich content, home video surveillance has gradually become the core content of smart security system. The rapid development computer technology, internet, image processing, transmission as well emergence “wireless cities,” have continuously expanded coverage wireless internet such 5G WiFi greatly changed data processing methods speeds. Video also developed...

A new attack against the Kirchhoff Law Johnson Noise (KLJN) secure key distribution system is studied with unknown parasitic DC voltage sources at both Alices and Bobs ends. This paper generalization of our earlier investigation a single end source. Under assumption that Eve does not know values sources, attack, utilizing current generated by dc introduced. The mathematically analyzed demonstra...

This paper proposes a cell search method to establish communication links between base stations (BS) and terminals in the dynamic parameter controlled orthogonal frequency and time division multiple access (DPC-OF/TDMA) systems. In the proposed cell search algorithm, a delay profile is first detected by taking auto-correlation between the received signal and its copy delayed by the useful symbo...

This paper presents a proposed scalable architecture to enable networked reconfiguration for the next generation communication terminals. A new system architecture that supports networked reconfiguration is defined. It contains two new blocks the virtual reconfigurable architecture (VRA) and the application specific resource manager (ASRM). VRA can be considered as a hardware virtual machine, a...

The transmission of multimedia data over networks has increased steadily over the past few years and this increase is projected to accelerate in the future. However, virtually all current products and research for multimedia traffic over networks have concentrated solely on transmission of multimedia applications to and from wired terminals. Excluding mobile terminals from multimedia applicatio...

In this paper we consider a stochastic queueing model for the performance evaluation of a real life computer system consisting of n terminals connected with a CPU. A user at terminal i has thinking and processing times depending on index i. First we discuss reliable models, and then unreliable models (i.e. the CPU and the terminals are subject to random breakdowns). The models described here ar...

The paper presents the authors’ experience in designing and implementing secure smart card and agent-based telecommunication services supporting user mobility and service personalization. The work described here has been performed as part of the EU ACTS SCARAB project and is based on a service architecture that has been defined by the SCARAB partners. User mobility is achieved both by using sma...
