Optical burst switching (OBS) is the promising area it can meet the bandwidth requirement of bandwidth intensive application. OBS is switching technique for the next generation optical networks. However, there are certain issues such as burst aggregation, scheduling, contention resolution and QoS that needs to be addressed in OBS. In this paper, we summarize the results of current research trends on optical burst switching networks. We present the classification of different scheduling algorithms and contention resolution techniques.

Optimal fault ride-through (FRT) conditions for a doubly-fed induction generator (DFIG) during a transient grid fault are analyzed with special emphasis on improving the active power generation profile. The transition states due to crowbar activation during transient faults are investigated to exploit the maximum power during the fault and post-fault period. It has been identified that operating slip, severity of fault and crowbar resistance have a direct impact on the power capability of a DFIG, and crowbar resistance can be chosen to optimize the power capability. It has been further shown that an extended crowbar period can deliver enhanced inertial response following the transient fault. The converter protection and drive train dynamics have also been analyzed while choosing the optimum crowbar resistance and delivering enhanced inertial support for an extended crowbar period.

Demands for low power electronics have motivated designers to explore new approaches to VLSI circuits. The classical approaches of reducing energy dissipation in conventional CMOS circuits include reducing the supply voltages, node capacitances, and switching frequencies. Energy-recovery circuitry, on the other hand, is a new promising approach to the design of VLSI circuits with very low energy dissipation. The supply voltage in adiabatic circuits in addition to providing the power to the circuit behaves as the clock of the circuit and for this reason is called power clock. One of the main concerns in the adiabatic logic circuits is the power clock generation. The design of a power clock generator is a challenging problem in this field. This paper discusses the design and simulation results of a VCO based power-clock supply generation for quasi-adiabatic circuits. The analysis is carried out in cadence design environment using 180nm technology using cell based design approach.

A high-frequency (HF) isolated DC/AC converter was proposed as the interface between a small-scale PMSG-based wind turbine generation system (WTGS) and a single-phase utility line in [4]. In this paper after a brief review of this configuration, different options of the multi-cell operation of this converter for high power wind generation applications are discussed. The effect of multi-cell operation on the harmonics on the input dc current and output line currents are addressed. It is found that both the 2nd harmonic in the input dc current and all triplen harmonics in the output line currents are eliminated when three identical single-phase converters in Delta connection are used. PSIM simulation results are included for the purpose of validation.

In this paper, a modified of Jena [1] remote user authentication scheme using smart cards based on Elliptic Curve Discrete Logarithm Problem (ECDLP) has been proposed. A remote user authentication scheme is a two-party protocol whereby an authentication server confirms the identity of a remote individual logging on to the server over an untrusted, unsecured network. The password based authentication schemes are commonly used for authenticating remote users. Many passwords based schemes both with and without smart card have been proposed; each scheme has its merits and demerits. However, the scheme proposed by Jena is vulnerable to the masquerade attack. In this paper, we shall discuss the masquerade attack on their scheme. Furthermore, we shall present an enhanced scheme for preventing the above attack.

This paper presents a development of a holonomic mobile robot with remote operation capability. Most of the currently available holonomic mobile robots find problems in field applications because they has not been adopted to field environment.To address those problems we have develop a holonomic platform with a capability of carrying 30 kg payload. This platform use normal car type wheels and a complex multi-processor control system controls each wheels steering and driving to achieve the correct holonomic motion. We have tested it in indoor and out door environments and it's design , hardware and control is presented in this paper.

An expression for the probability density function of the sum of independent and identically distributed random variables is derived. The new expression is in the form an infinite series containing Laguerre polynomials. This series is applied to determine the error rate performance for EGC diversity reception of CPSK signals in Nakagami fading channels. The density function of sum of Nakagami random variables is evaluated and graphically displayed. Numerical values for the error rate of CPSK signals for EGC diversity are presented

Specification based testing involves using specification as the basis for generating test cases. The Unified Modeling Language (UML) consists of diagrams to capture the static and dynamic behaviour of a system. Generating test scenarios using UML activity diagrams produces all possible scenarios which is impossible to test exhaustively. Test scenario selection involves selecting an effective subset of scenarios for testing. This paper presents a new metric based on common subscenario between scenarios, their lengths, and weights based on the position of the common subscenario in the scenario. The aim of this strategy is to select scenarios that are least similar and at the same time provide high coverage. The method is compared with results of random selection to study effectiveness of our technique.

This paper presents a more precise approach for static electromagnetic characterization of the variable speed switched reluctance generator (SRG) for application in the wind energy conversion system. The circuit-coupled two-dimensional finite element method (FEM) [2] for magnetic characterization of switched reluctance generator is presented. This approach yields more accurate results for a low speed switched reluctance generator with multiplicity of four. The magnetic characteristics such as flux linkage characteristics, inductance profile and torque profile have been obtained in a more accurate manner using this approach.
