Encoder circuits are vital component of an electronic computer system. Encoders are generally used for the conversion of a 2" bit number into the n bit number. Applications of encoders can be visualized as keyboard encoder on widespread use. Design of an optimized encoder circuit with the concept of reversible logic is the main outcome of this research paper. The concept of reversible logic has become burgeoning tool for the designing of efficient digital circuits with low power dissipation. This paper provides a possible approaches to design a decimal to BCD encoder using reversible logic gates. Optimization of the circuit has been explored on the basis of minimization of some performance parameters such as number of reversible logic gates used in the designing, garbage outputs generated during the operation of the circuit and quantum cost of the circuit.

The acoustic noise and vibration are major problems for Switched Reluctance Motor (SRM) to be used in electric vehicles, many industrial and household applications. Torque ripple is major cause of Acoustic noise and vibration in SRM. Discrete nature of current pulses applied to the motor causes ripple in the electromagnetic torque generated by a SRM. This Torque ripple can be reduced by design variation of stator/rotor magnetic structure of SRM, proper coordination of current pulses between incoming and outgoing phases. In this paper analysis vis-à-vis design for torque ripple variation has been carried out. Design optimization has been done with reduction in torque ripple from the original design. A V, U, m shape culvert's are made at the unaligned position of rotor for the optimized design and torque ripple is analyzed. FEM analysis is used to determine torque variation.

This paper proposes an extended approach for order reduction of high order interval models through stability preservation approach. The numerator and denominator of reduced order model are obtained by β & α table respectively. The proposed method is computationally simple and preserves the stability of reduced order system if higher order system is stable. A numerical problem is discussed to exemplify the algorithm. Further, approximation error between the higher order and reduced order system is determined to demonstrate the efficacy of the proposed technique.

In the present work, an in-depth study of methane adsorption on bamboo-like carbon nanotubes (BCNTs) has been accomplished. The structures of (12,0) and (5,5) BCNTs have been designed and optimized using Quantumwise Atomistix Toolkit software package. The main reason behind employing BCNTs is their unique geometry i.e. the presence of hollow compartments due to which more number of CH4 molecules get adsorbed. The methane molecule adsorption on the various sites of BCNTs have been considered in order to observe and compare the modified structural and electronic properties of the two BCNTs. The comparative analysis depicts that CH4 molecule gets adsorbed suffer with higher adsorption energy to (12,0) BCNT surface than that of (5,0) BCNT surface.

A single-phase series active compensator is proposed to mitigate voltage sag, swell and voltage harmonics along with reducing harmonic currents at the AC mains. The DC link capacitor of the series active compensator is shared with a voltage fed load thus having a common DC link. The common DC link has an advantage of reduced component and immune to the wide variation in the voltage of AC mains, thus avoids the derating of the load. The proposed series active compensator provides the functions of mitigation of voltage sag/swell, voltage harmonics, current harmonics and regulating the DC link voltage.

Images and videos captured by cell phones are very important carriers of information amongst user generated multimedia contents. These carriers can be used in solving many forensic problems such as identification of movie piracy, insurance cases, child pornography, and other applications involving identifying/verifying source cell phones. This paper evaluates the effectiveness of Image Quality Measures (IQM) for identifying the source cell phone from the images or videos captured by that cell phone, by comparing the classification accuracies obtained for these two scenarios. Twenty-eight IQM features for each image and selected video frame are extracted and then classified using the Rotation forest classifier of WEKA. The proposed method is tested on 900 images and 1,350 short videos from nine different cellphones, some of which are of same brands and models. The experiments demonstrate that due to larger compression artifacts in videos, IQM are less effective for video based source cell phone identification as compared to image based source cell phone identification.

The comparison of control strategies of two different topologies of five level diode clamped multilevel inverter (DCMLI), fed by a photovoltaic (PV) module is presented in this paper. The inverters are supplying various dynamic loads. Different types of single phase induction motors have been used as dynamic loads. The control strategies implemented are Phase disposition (PD), Phase opposition disposition (POD), Alternate phase opposition disposition (APOD) and unsymmetrical sine pulse width modulation for the classical five level diode clamped inverter. This topology is compared to another inverter topology that is free from the problem of voltage collapse and needs lesser number of capacitors and clamping diodes. The simulations have been performed using Simulink package of Matrix Laboratory (MALAB) software. The output voltage and output current Total Harmonic Distortion (THD) is analyzed for each of the control strategies. Relative comparison is undertaken for both topologies. The single phase induction motors are loaded by a variable load.

The use of Electronic Stability Control (ESC) in automobiles has become quite popular in the last decade and a number of research activities have been conducted for its further improvement. The use of these complex systems has reduced the number of accidents reported on highways and expressways around the world. The adaptive front lighting system has also undergone extensive research in the past decade and has proved very effective in increasing the stability of the vehicle while driving. A large part of literature available in this area enlightens about the effectiveness of ESC in situations where there is a risk of crash. In this paper, ESC and adaptive front lighting system have been implemented on a microcontroller to bring out the working of these complex systems. The model presented in this paper may be fabricated at a very low cost. It may also be incorporated in vehicles lacking this beneficial technology with minor modification.

Modern day high resolution data acquisition systems essentially uses sigma delta converters to achieve superior performance. These data converters utilize inbuilt Sine filtering (low pass) to remove high frequency noise shaped by sigma delta modulators. Sine filters are also called cascaded integrated-comb (CIC) digital filters. Sine filters implementation does not require multiplication therefore their realization in hardware devices is convenient. Nevertheless, these filters suffer from the problem of pass band droop (non-flat pass band), which worsens with increasing order of the filter and also from stop band ripples. This paper introduces a design and implementation of equiripple FIR filter to compensate the pass band droop in Sine filter response. The design can be implemented in any simple microcontroller such as PIC microcontroller, without using the multiplier unit. Paper also presents the results of the simulated equiripple FIR on PIC microcontroller simulator environment MPLAB IDE. The stop band ripple characteristics of the compensated filter are also discussed. This kind of implementation is suitable for high resolution telemetry system which uses embedded Sigma delta converters along with microcontroller or DSP processors. sheet.

This paper presents a fault detection and classification scheme, based on integrated impedance, for SVC compensated transmission line. For internal faults, integrated impedance of faulty phase is low and for healthy phase, it is high. For all external faults, integrated impedances of all phases are high. The protection scheme based on this concept is used for variable impedance shunt compensation (i.e. Static Var Compensator, SVC). Proposed scheme has been analyzed for each phase with different fault resistances, fault types and fault locations. The results demonstrate the effectiveness of the proposed scheme.
