Shaili Jain, Shashilata Rawat and Monika Kapoor

Of late all the organization of world are approaching the high speed processor towards the fast digital communication. In this paper we are going to propose a method to develop fast convolution technique. Convolution is the bottleneck technique for digital signal processing, image processing and other signal analysis. Proposing convolution method is comprised with multiplier and adder. With this concern we need to design a fast multiplier and adder which are also main components of processor design. Calculation of partial product will be handled by Vedic Mathematics named as Urdhva Triyagbhayanm sutra. In this paper we are using Kogge Stone device for fast speed multiplication and addition. Simulation and synthesize will be done on 14.2i Spartan 3 series of Xilinx.

Devendra Kumar Choudari and Jitendra raghuwanshi

Effective shooting of solar energy is of great importance as phase of discovering a answer for the ever-increasing demand for energy coupled with the depletion of resources of fossil fuels. The area of Bhopal city in the india is related with distinctly high levels of atmospheric dust concentrations. This causes high costs of dirt accumulation on photo voltaic collectors, which decreases the whole energy yields. Therefore, minimizing the quantity of dust that accumulates on pinnacle of the solar collectors is of outstanding importance for photo voltaic electricity utilization in widespread and for the Masdar Initiative and Bhopal City in particular. The objective of this lookup used to be to advance a mannequin that describes dust accumulation in order to understand the elements that affect the utilization of PVs in an area with high dirt concentrations. Subsequently, we moved on to address the hassle of dirt accumulation through trying to relate the rate of dust accumulation to special climate conditions. Although our facts had a restrained time resolution, we managed to describe qualitatively the dust accumulation dependence on numerous weather parameters. We additionally proposed a new experimental framework that improves the time decision of our experimental setup that approves collecting the one of a kind parameters that want to be studied in order to be able to advance a quantitative model that describes dirt accumulation. A mannequin for dust accumulation mixed with a mannequin that describes the PV strength output willenable us to better predict the energy output and energy yields on one hand, and to optimize the cleansing of PV modules on the other. Also such a mannequin will assist us in developing functionalized coatings that reduce dirt accumulation via figuring out and appreciation the elements that affect dirt accumulation.A cleansing machine for Solar panels consists of a variety of solar cells and a transparent protection pane protecting the Solar cells.

Rahul Ranjan Yadav, Yogesh Dewang and Jitendra Raghuvanshi

Extrusion is a manufacturing process used to create objects of a fixed cross-sectional profile. A material is pushed through a die of the desired cross-section. A brief and concise review of the contributions made by the previous researchers in the area of extrusion process has been presented. Steel material and aluminium alloys are mostly used by researchers as die and billet material in extrusion process. FEM modeling of extrusion process is carried out by employing axisymmetric conditions in most cases. Meshing of the work piece is generally done by using axisymmetric quadrilateral elements. Experimental set-up and tools utilized in formation of extrusion process are presented and discussed. FEM results are presented in terms of variation of punch stroke, punch force.

[5] Stability analysis and fault critical clearing time evalution of 3-machines 9-bus

Pratidhwaj Bhargava and Vivek Rai

Power Systems Stability Study is an important parameter for financial, reliable and safe power system planning and operations. Power system studies are important from time to time during project planning and conceptual design phases as well as during the operational life of plants. This paper presents the power system stability analysis for IEEE-9 bus system. The Fault is created on different buses (Bus 5) and transient stability is analysed for different load and generation conditions. The critical clearing time (CCT) is calculated by the time of the domain classical extended equal field criteria. The system Frequency and voltage variance is observed for different fault location and CCT. The IEEE-9 bus test system is simulated and stability is analysed. Electrical power system is a network of electrical components in which power supply, transfer and use of power is included. The power system is also explained as a grid, which can be widely divided into generating systems which supply the power power, transmission system, which passes from the generated centers to the power stations and the distribution system, which is nearby Provides electricity to homes and industries. Power system is designed to provide continuous power supply, which maintains voltage stability. However, due to unwanted incidents such as lightning, accidents or any other unexpected event, short circuit between transmission lines or between one phase wire and ground is called fault. Due to fault, due to imbalance between generation and demand one or more generators can be seriously distressed. If the fault persists and is not cleared in a pre-specified time frame, it may cause severe damages to the devices which leads to a power loss and power sources. Therefore, protective equipment's are installed to detect faults and clear and isolate faulted parts of the power system as quickly possible before the fault energy is propagated to the rest of the system. Transient stability analysis place and important role of planning, designing and upgrading an exciting electrical power system network. In this thesis, transient stability analysis is carried out by considering are three phase faults at the bus bar 5 with the effect of fault clearing time. The simulation is carried out Ring Main method. It is found that at fault clearing times of 0.0705 sec the generators (G2, G3) under test are stable with respect to simulation time. In addition, it has been demonstrated that the transient stability of a system can v improved using controlled devices.

Pradeep Upadhyay and Ramanand Singh

Due to the increasing spread of digital computing, investigation of various number representation systems in the digital field seems necessary. In general, the number representation systems regarding their applications can be classified in two areas: general-purpose and specific-purpose. Binary Digit Residue Number System (BD-RNS) is one of the specific-purpose and optimized number system. In Residue Number System-based systems, how to select moduli set and evaluate its performance is an important issue. The objective of this study is to propose a systemic performance evaluation method for RNS based on the properties of moduli set. By abstracting the inherent properties of moduli sets, such as the complexity of arithmetic units, utilization ratio of dynamic range, parallelism and balance between residue channels, this method can provide advices on moduli set selection and carry out performance estimation before circuit's implementation.
