Abstract: Multilevel inverter has appeared as one of the important topologies in the area of high power and medium voltage situation. These “multilevel inverters” have attracted numerous applications irrespective of the power ratings because they can efficiently realize lower harmonics with reduced switching frequency and also produce high voltages with reduced “Total Harmonic Distortion” (THD). This paper uses MOSFETs and IGBTs to model “Diode clamped” and “Cascaded H-bridge multilevel inverter” and analyse the harmonic content. In addition, through a comparative analysis of the topologies, this paper demonstrates the features of the different “multilevel inverter” topologies. The performance of the proposed topologies is realised using MATLAB/Simulink.

Abstract: In this undertaking we have clarified about the exhibition of IEEE-6 transport framework by utilizing Mi power innovation. In the past venture the heap stream investigation and soundness examination was found by utilizing Mi power programming. This venture shows the short out examination by utilizing MI power innovation. The greatest and least genuine and receptive force limits have been set and the outcomes are acquired. The yield result was discovered more proficient contrasted with the past model. All the force framework gears were intended to withstand high proficiency and to withstand most pessimistic scenario condition. The MI power programming is the cutting-edge innovation so as to improve the heap stream investigation, steadiness examination, short out and possibility investigation. This venture clarifies about the MI power programming to which it raises the efficiencies for the estimation of short out examination. This venture clarifies about the distinctive shortcoming conditions, for example, balanced and unsymmetrical issue investigation in which we are thinking about the short out examination. The transient and sub transient parts are to be found and the framework prompts the steady condition.

Keywords: Mi power, short circuit analysis, symmetrical and unsymmetrical analysis.

Abstract: The primary aim of the study was to determine the differences of muscular endurance and muscular strength. Total students 15 Kabaddi and 15 Kho-Kho players participated in the study and their age ranged between 18-30years. The demographic information about Gender, age, daily smoking, drug use, etc. was obtained before seeking responses. The study area was restricted to Marathwada region of Maharashtra Muscular Endurance was evaluated by using 1 minute Bent Knee Sit Up test. Abdominal muscular endurance was measured by performing the 1-minute bent knee sit-up test. The findings of the study indicates that Kabaddi Players was found to have got more Muscular Endurance and Muscular Strength as compare to their counterparts.

Abstract: Pixels of the digital images has been corrupted by noises came out of faulty communication channel or non- linear sensors. Such noise models can be either Salt & pepper noise (impulse noise) or Gaussian noise. Sometimes both of the noises corrupt the same image; such combination of two noise model is called as mixed noise. These noises can be removed by using image filtering algorithms. The most popular image filtering algorithm is median filters. Two models of median filters, that are simple median filter and switching median filter has been discussed in this paper. Fuzzy logic controller has been discussed in details so that its combination with median filters can be discussed for future work. Terminologies like fuzzy logic operator, membership functions and fuzzy rules have been discussed. Quality parameter PSNR (Peak Signal to Noise Ratio) has been studied to find the quality of image numerically.

Keywords: Switching median filter, Fuzzy logic rules, Mixed noise, PSNR, Membership functions, Fuzzification, Image filtering.

Abstract: Carry-Look Ahead adder is one of the essential components used in different digital logic circuits for its fast and efficient computation capability. This paper primarily focuses on the design and simulation of 4-bit CLA adders which are implemented using two different technological perspectives, the conventional CMOS technology using VHDL and Quantum Computing using Quantum-dot Cellular Automata (QCA). Both designs are based on reversible logic to reduce heat dissipation, better testing of faults in circuits, and nearly energy-free computation. VHDL has been the most effective hardware descriptive language when it comes to digital circuit designs but with the advancement of technology, implementation of circuits using QCA is considered an alternative approach. This research work will impart an in-depth comparison between the two domains of technology on one of the most useful combinational logic circuits, the CLA Adder.

Keywords: CLA Adder, Quantum Cellular Automata, VHDL, Reversible Logic Gates.

Abstract: This paper deals with the reactive power compensation and better mitigation of transmission related problems in today’s world for a profound reliability of the offered power quality. we look at the FACTS controller being used for both series and shunt compensation. In that study shunt operation of the STATCOM and its principles of operation, control and how it helps in the better utilization of a network operating under normal conditions. A control system was developed to compensate unbalance reactive power and it was simulated using MATLAB. Simulation results confirm that the STATCOM compensates unbalance reactive power at the load.
