The analysis and control of multi-input integrated DC-DC converter is presented in this paper. The integrated converter is essentially a combination of buck and buck-boost converters. However, on account of integration only one inductor is sufficient enough for performing the power conversion. In order to have simple control strategy as well as simpler compensator design a single loop control scheme, voltage-mode and current-limit control, are proposed here for the power distribution. Closed-loop converter performance of this converter is simulated and compared with the theoretical predictions. Experimental measurements are provided for validating the control concept.

Transmission of video summary frames through wireless networks needs higher bandwidth with less delay and distortion constraints as continuous media playback is necessary at the receiver. So the joint optimization of application layer with lower layers is necessary to meet certain QoS requirements. In this paper, we propose a Cross-layer design approach that jointly optimizes the physical layer, data link layer and application layer for the transmission of video summary frames through wireless networks based on MIMO transmit/receive diversity with AMC at the physical layer and ARQ at the data link layer and source coding at the application layer. We model the finite-state Markov chain(FSMC) for the physical layer service and based on that, we then characterize the Lagrangian relaxation and Dynamic programming to find the optimal shortest path. The source coding as well as retransmission requests are based on the channel-state information (CSI) and the system controller is implemented in all the three physical, data-link and application layers. The numerical results revealed that our proposed cross-layer model with MIMO diversity schemes can efficiently achieve the distortion gain with same delay budget.

Mobile ad hoc networks are a class of dynamic networks without any centralized administration. A major bottleneck in mobile ad hoc networks (MANETs) is the energy consumption since nodes are usually mobile and battery operated. To maximize the lifetime of mobile ad hoc networks (i.e., the lifetime of the nodes themselves) the power depletion of network must be evenly distributed, i.e., there must be a uniform drain of energy from the nodes, and the overall transmission power requirement for each connection request must be minimized. This paper proposes two algorithms called energy efficient delay time routing (EEDTR) and maximised energy efficient routing (MEER), which try to increase the operational lifetime of mobile ad hoc networks. These algorithms are modified versions of the existing dynamic source routing (DSR) algorithm. These algorithms select fully distributed routes, thus balancing power consumption of the entire network. The first algorithm(EEDTR) introduces a delay in forwarding the packets by nodes, which is inversely proportional to the remaining energy level of the node. The second algorithm includes energy information on the route request packet and select the routes based on this information (MEER). These algorithms are designed and implemented using global mobile simulator (GloMoSim), a scalable, simulation environment for network simulation. Based on the results obtained, this paper concludes that the proposed algorithms increase the lifetime of mobile ad hoc networks, at the expense of end to end delay and control overhead.

In this paper, a novel drive topology for a five phase stepper motor is described in detail. Commercially off the shelf, low cost, standard stepper motor drive ICs are used to derive a novel drive topology for five phase stepper motors which enables closed loop speed and position control powered by inner current control loop. It is proved that the derived topology can be generalized to any stepper motor with higher odd number of phases. The designed driver consists of full step, half step, clockwise and counter clockwise drive modes with the speed control and current control.

This paper presents a genetic algorithm (GA) based approach to solve the optimal power flow (OPF) with FACTS devices to eliminate line over loads in the system following single line outages. The optimizations are performed on two parameters: the location of the devices, and their values. Two different kinds of FACTS controllers are used for steady state studies: thyristor controlled series capacitors (TCSCs) and thyristor controlled phase shifting transformers (TCPSTs). The proposed approach uses an index called the single contingency sensitivity (SCS) index to rank the system branches according to their suitability for installing TCSC and TCPST. Once the locations are identified, the problem of determining the optimal TCSC and TCPST parameters is formulated as an optimization problem and a GA based approach is applied to solve the optimal power flow (OPF) problem. Simulations are done on IEEE 30 bus system for a few harmful contingencies.

Network coverage of wireless sensor network (WSN) means how well an area of interest is being monitored by the deployed network. It depends mainly on sensing model of nodes. In this paper, we present three types of sensing models viz. Boolean sensing model, shadow-fading sensing model and Elfes sensing model. We investigate the impact of sensing models on network coverage. We also investigate network coverage based on Poisson node distribution. A comparative study between regular and random node placement has also been presented in this paper. This study will be useful for coverage analysis of WSN.

Use Cases describe behavioral requirements of software systems in textual form. They are interpreted for creation of analysis, design and implementation artifacts, including user interface (UI). There is a very likelihood of inconsistencies in the interpretation of the Use Cases by different members of software development team. Various research efforts have been made to associate a formal model with the Use Cases to minimize such inconsistencies. In this paper we present a Use Case editor which uses restricted form of natural language and generates a finite state machine (FSM) model of the Use Case including UI requirements. The editor views a Use Case as an ordered set of event-response pair with parameters. These parameters provide input and output requirements of UI. The semantics of a Use Case and its events are captured in terms of pre and post conditions, which are used to generate states and transition rules of FSM. Both state and transition rules of FSM are represented as typed graph. UI implementation is also modeled as typed graph. We have defined consistency criteria between UI requirement and its implementation, and have used a graph based simulator tool, GROOVE for verification of consistency. The editor generates XML files compatible with GROOVE to facilitate this consistency checking.

This paper investigates the scope of genetic algorithms (GA) for performance improvement in multiuser detection through the realization of an efficient block parallel interference cancellation (PIC) technique in a synchronous carrier interferometry/MC-CDMA (multicarrier-code division multiple access) uplink system. Simulation is carried out on frequency selective Rayleigh fading channel and antenna diversity is applied at base station (BS). Weight factors for diversity implementation are calculated based on the value of SIR (signal to interference ratio) of individual antenna system. GA is used to partition different users into groups of different blocks namely very strong, strong, weak and very weak based on the normalized magnitudes of their decision variables. We have reported the performance of the GA based block PIC system of four block, three block and two block with conventional PIC. A significant improvement in performance and capacity is seen with GA based block PIC relative to conventional PIC at the cost of slight increase in computation complexity. Simulation results show that BER is reduced as the number of users are divided into more number of blocks and the optimal partitioning of the blocks obtained by using GA.

A novel zero-voltage switching (ZVS) step-down converter with a tapped inductor is proposed in this paper. Tapped inductor provides better power density as compared to isolation buck converter. With a simple structure, the tapped-inductor buck converter shows promise for extending the duty cycle. This converter is cost effective and attractive for high performance. Furthermore, with the replacement of transformer by tapped inductor, its efficiency may be maximized for low power application and power quality is improved as low harmonics at input as well as output. The peak current of the main switch is reduced by tapped inductor operation, thus the conduction loss and switching loss levels of the main switch are lowered. Consequently, this tapped inductor scheme alleviates the severe power stress and enhances device utilization. This soft-switching buck converter is suitable for extremely low step-down ratio applications. The principle of the proposed scheme, analysis of the operation, and design guidelines are included. Finally, the experimental result of the 10 W prototype DC/DC converter is given for hardware verification.

This paper highlights the use of measurement uncertainty in decision making for application of specific Test & Measuring (T & M) equipment in the measurement process with certain level of confidence. The study conducted on DMM (digital multimeter) and the uncertainty is estimated focusing on technical & human influences. The test set-up is automated and the measured parameters are traceable to national standards. The poor decision on choosing T & M equipment for the measurement of data causes huge loss, which is irrecoverable. Before taking any final recommendations or decisions, the due importance is to be given to calibrated measurement data & the associated uncertainty. The objective of the case study is to focus on certain potential components instead of all the causes, which are having less importance in the measurement process. This will help in reducing the measurement time with qualitative output.
