Step By Step Numerical Approach to a Self-Sufficient Micro Energy System Design
Step By Step Numerical Approach to a Self-Sufficient Micro Energy System Design
Abstract: This paper presents a numerical approach to self-sufficient energy-system design. The main focus is to describe the methodology of designing an approach in several steps to find an optimally structured micro-energy system in accordance with the introduced decision parameters. A specific system model is presented that consists of an energy consumer, renewable and non-renewable energy-production facilities, energy-storage capacities and a control unit. Different operating conditions were identified for the system and various system configurations were simulated. Based on the input data and the decision parameters an optimal system was chosen that is able to provide a stable and optimal energy supply. The optimal configuration was found using the WSM method. The result is a specific structure of the energy system that meets all the requirements and boundary conditions of the presented numerical approach. Finally, the operation of the system is presented via timeline charts.
Key words: numerical model, energy system, optimization, operating regimes, RES, costs, energy demand, Matlab

Structural and Morphological Properties of Cr2O3 Nanoparticles Synthesized By Novel Solvent Free Method
Structural and Morphological Properties of Cr2O3 Nanoparticles Synthesized By Novel Solvent Free Method
Abstract: Nanoparticles of chromium oxide (Cr2O3) are widely used in many fields serving as catalysts, wear resistance materials, and advanced colorants. For the first time, we have reported the solvent free synthesis of Cr2O3 nanoparticles via microwave irradiation followed by calcinations at 200, 400, 600 and 800°C for 1h. The influence of calcination temperature on the particle size, microstructure and morphology was examined by X-ray diffraction, Scanning Electron Microscope (SEM) and Transmission Electron Microscope (TEM), Elemental compositions have been estimated by energy dispersive X-ray Absorption EDAX and thermo gravimetrv analysis (TGA-DTA). The average particle size of the synthesized Cr2O3 nanoparticles is calculated using the Scherrer's formula and found to be of less than 60 nm and is compared with Williamson Hall method . It is found that the molar ratio 1:3 is considered to be the best proportion to synthesis Cr2O3nanoparticles. These results also indicate that there is an improvement in the crystallinity of Cr2O3 nanoparticles with the increase in the annealing temperature. As the process is simple and low-cost, it has the potential to be produced on a large scale.
Key words: Nanoparticles, chromium oxide, microwave irradiation, calcined.

A Low Power Viterbi Decoder for Trellis Coded Modulation System
A Low Power Viterbi Decoder for Trellis Coded Modulation System
Abstract: Forward Error Correction (FEC) schemes are an essential component of wireless communication systems. Convolutional codes are employed to implement FEC but the complexity of corresponding decoders increases exponentially according to the constraint length. Present wireless standards such as Third generation (3G) systems, GSM, 802.11A, 802.16 utilize some configuration of convolutional coding. Convolutional encoding with Viterbi decoding is a powerful method for forward error correction. Viterbi algorithm is the most extensively employed decoding algorithm for convolutional codes. The main aim of this project is to design FPGA based Viterbi algorithm which encrypts / decrypts the data. In this project the encryption / decryption algorithm is designed and programmed in to the FPGA.
Key words: Viterbi Decoder, Convolutional Encoder, Forward Error Correction technique.

Performance Enhancement of a Novel Interleaved Boost Converter by Using a Soft-Switching Technique
Performance Enhancement of a Novel Interleaved Boost Converter by Using a Soft-Switching Technique
Abstract: In this paper a novel Interleaved Boost Converter (IBC) with soft-switching techniques is proposed. Through the zero-voltage switching (ZVS) and zero-current switching (ZCS) reduces the current stress of the main circuit components, in addition to this it can also reduces the ripple of the input current and output voltage. In this approach, it can be faster switching, reduce the size and cost with suitable impedance matching is achieved with reduction in auxiliary circuit reactance that has contributed much increase in the overall performance. Coupled inductor in the boosting stage helps higher current sharing between the switches. The overall ripple and Total harmonics distortions are reduced in this technique without sacrificing the performance and efficiency of the converter. The driving circuit can automatically detect operational conditions depending on the situation of the duty cycle whether the driving signals of the main switches are more than 50% or not and get the driving signal of the auxiliary switch. Auxiliary circuit acts as support circuit to both main switches(two conditions) and reduce the total losses and improve efficiency& power factor for large loads. The operational principle, theoretical analysis, and design method of the proposed converter are presented. The entire proposed system will be tested using MATLAB/SIMULINK and the simulation results are also presented.
Key words: Interleaved Boost Converter(IBC), Zero-Voltage Switching (ZVS) & Zero-Current Switching (ZCS)

Effect of 3 concentration of finishing agents was observed on thick, medium and fine thickness of cotton khadi. It was found out that amount and size of the finishing agents affect the stiffness and drape of khadi fabric. Maximum increase in stiffness and drape was seen in fabric treated with revive and minimum in silicone treated fabric. Significant difference in stiffness and drape of fabric of different thickness was also found.

Analysis Based On Ansys of PCC Deep Beams with Openings Strengthened With CFRP
Analysis Based On Ansys of PCC Deep Beams with Openings Strengthened With CFRP
Abstract: Reinforced concrete deep beams have wide range of applications and are used in gigantic structures to bear heavy loads. An opening in the deep beam decreases the load carrying capacity and reduces its serviceability. A PCC (plain cement concrete) deep beam with dimension 8000*5000*800mm (L*D*B) is modelled and analysed in ANSYS under uniform loading and simply supported conditions. The position of the circular hole with single and double opening is varied longitudinally and over the depth of the beam. The same beam is then analysed in ANSYS before and after assigning the CFRP (carbon fibre reinforced plastics) laminates along the inner surface of the opening. Stress in horizontal direction is studied in element below the CFRP laminate keeping loading condition, element type, and material properties constant. Thus the strength of the deep beam is a function of CFRP laminates as well as position of circular hole.

Abstract: This paper mainly deals with the analysis of queueing system in which customers require services in two stages are common. Two-phase queueing systems are gaining importance due to their wide variety of applications. Batch mode service in the first phase followed by individual service in the second phase. Because of the mixed mode of services, these kinds of two phase queues do not fit into the usual network of queues as a particular case. The need for this kind of modeling has been greatly discussed in this paper
