Abstract

Multiwire Proportional Counter (MWPC), a particle studied under this project is an indispensable part of all nuclear physics experiments involving the study of compound nucleus and fission fragments. The work done under this project involves the fabrication, assembly and testing of a MWPC. The experimental work has been done at Inter University Accelerator Center (IUAC), New Delhi. The MWPC fabricated at IUAC had an active area of 16x11 cm2. Timing resolution and gain of the fabricated MWPC was made to improve over that of already available MWPCs at IUAC by reducing the anode wire pitch and using a ten micrometer diameter wire for anode frame. The fabricated MWPC was thoroughly tested with an alpha source and it was observed that the detector could handle heavy count rate exceeding 20 KHz without any breakdown. Fabricated MWPC was also used in a nuclear physics experiment in the NAND experimental set up of IUAC to extract information about mass, kinetic energy and angular distribution of fission fragments. All the detailed investigations done with the detector were part of the M.Sc. Dissertation work of the first two authors. During under graduation and post-graduation, students study about proportional counters with emphasis on their construction and basic principle of operation. However, this project work provided the first two authors with a unique opportunity of getting a practical experience on how these proportional counters are fabricated and their importance in the field of nuclear physics. Thus, project based learning leaves a larger impact on the mind of the students as far as understanding of concepts of science is concerned Introduction A multi wire proportional counter is simply a gas filled wire chamber consisting of a large number of anode wires stretched in a plane for position measurement. The original motivation of developing such detectors came from the need to track particles in high energy physics experiments. The wire chambers, thus developed worked amazingly well and helped scientists make grea discoveries at particle accelerators. Although these chambers are still used in some laboratories, but since the advent ofhigh resolution silicon detectors their utility has somewhat diminished. Fig.1 shows the sketch of a typical multi wire proportional chamber [1]. The closely spaced thin anode wires are stretched in a plane that is midway between two cathode planes. The cathodes are kept at negative potential with respect to anode wires that are kept at ground potential. Each of the anode wires acts as an independent proportional counter and must therefore be read out independently [2]. For full article .... Visit Site ...www.ijsrd.com

Transient Stability of Power System using Facts Device-UPFC

IJSRD Found one good reserch article on Electrical Engineering Department

Abstract— This paper is based on Occurrence of a fault in a power system causes transients. To stabilize the system, The Flexible Alternating Current Transmission (FACTS) devices such as UPFC are becoming important in suppressing power system oscillations and improving system damping. The UPFC is a solid-state device, which can be used to control the active and reactive power.. By using a UPFC the oscillation introduced by the faults, the rotor angle and speed deviations can be damped out quickly than a system without a UPFC. The effectiveness of UPFC in suppressing power system oscillation is investigated by analyzing their oscillation in rotor angle and change in speed occurred in the two machine system considered in this work. A proportional integral (PI) controller has been employed for the UPFC. It is also shown that a UPFC can control independently the real and reactive power flow in a transmission line. A MATLAB simulation has been carried out to demonstrate the performance of the UPFC in achieving transient stability of the two-machine five-bus system.

I. INTRODUCTION

The UPFC is the most versatile of the FACTS devices. The main function of the UPFC is to control the flow of real and reactive power by injection of a voltage in series with the transmission line. Both the magnitude and the phase angle of the voltage can be varied independently. Real and reactive power flow control can allow for power flow in prescribed routes, loading of transmission lines closer to their thermal limits and can be utilized for improving transient and small signal stability of the power system.  

Fig. Schematic diagram of UPFC

The UPFC consists of two branches. The series branch consists of a voltage source converter, which injects a voltage in series through a transformer. The inverter at the input end of the UPFC is connected in shunt to the AC power system and the inverter at the input end of the UPFC is connected in series with the AC transmission circuit. Since the series branch of the UPFC can inject a voltage with variable magnitude and phase angle it can exchange real power with the transmission line. However the UPFC as a whole cannot supply or absorb real power in steady state (except for the power drawn to compensate for the losse.

The Unified Power Flow Controller (UPFC) was proposed' for real turn-off time control and dynamic compensation of ac transmission systems, providing the necessary functional flexibility required to solve many of the problems facing the utility industry. The Unified Power Flow Controller consists of two switching converters, which in the implementations considered are voltage sourced inverters using gate thyristors valves, as illustrated in Fig. These inverters, labeled "Inverter1" and "Inverter 2" in the figure, are operated from a common dc link provided by a dc storage capacitor. 

This arrangement functions as an ideal auto ac power converter in which the real power can freely flow in either direction between the ac terminals of the two inverters and each inverter can independently generate (or absorb) reactive power at its own ac output terminal since the series branch of the UPFC can inject a voltage with variable magnitude and phase angle it can exchange real power with the transmission line. However a UPFC as a whole cannot supply or absorb real power in steady state (except for the power drawn to compensate for the losses). Unless it has a power source at its DC terminals. Thus the shunt branch is required to Transmission Line Shunt Transformer VSC2 VSC1 Control Transient Stability of Power System Using Facts Device-UPFC (IJSRD/Vol. 1/Issue 3/2013/0025) All rights reserved by www.ijsrd.com 507 compensate (from the system for any real power drawn/supplied by the series branch and the losses. if the power balance is not maintained, the capacitor cannot remain at a constant voltage. Shunt branch can independently exchange reactive power with the system.

#ijsrd What is an electronic journal ?

What is an electronic journal?

An electronic journal is a periodical publication which is published in electronic format, usually on the Internet.
Electronic journals have several advantages over traditional printed journals:

1. You can search the contents pages and/or the full text of journals to find articles on a certain subject.
2. You can read journal articles on your desktop, you don't have to be in the Library.
3. You can e-mail articles to yourself or download them for printing.
4. The article that you want to read will always be available, even when the Library is closed.
5. Hypertext links allow you to move to different sections within individual journals or articles and can link you to related resources on the Internet.
6. Journals can include more images and audio-visual material.
7. Journals can be interactive - you can e-mail the author or editor with your comments.

Many electronic journals which are available are electronic versions of journals which exist in print. For example, if you wanted to see the journal called "Man" this journal is available physically on Level F in the Library, but is also available to SOAS users in electronic format.
Some journals are only available in electronic format and although some of these journals are of a high "academic" quality, please be aware that not all of them have gone through the same process of academic peer review as traditional print journals.

CFD Simulation of Compact Type Mini Channel Heat Exchanger by Using of Water

Abstract—A heat exchanger is a device that is used to transfer thermal energy (enthalpy) between two or more fluids, between a solid surface and a fluid, or between solid particulates and a fluid, at different temperatures and in thermal contact. In the conventional heat exchangers, pipes are larger in size which makes heat exchanger bulky. But in some typical applications such as closed loop gas turbine heat exchangers, cryogenic applications, heat exchangers used in PWR power plants, nuclear submarines, etc., size and weight are critical design constraints on the heat exchanger. Also for high pressure applications tubes are subjected to high bending stresses. To overcome these difficulties, compact heat exchangers can be employed. Mini channels heat exchanger is a type of compact heat exchanger in which mini channels are machined on metal plates and then such plates are bonded together. Such an arrangement provides high strength so that it can be used for high pressure applications. It has been observed that in mini channels, convective heat transfer coefficient is more than the tubes used in conventional heat exchangers. Hence, the length for same heat transfer is greatly reduced which results in reduced overall size and weight of the heat exchanger. Electronic device are in heavy demand for computer processor applications and generate large amount of heat. These high power device can be cooled off very effectively by either liquid or gas coolant flowing through micro or mini channels. Continuous research work is ongoing for developing high speed processor which generate high amount of heat. Cooling of such particular systems requires high amount of mass flow rate and compactness is also required. In present work, a mini channel heat exchanger is designed with assuming inlet and outlet of hot temperature, inlet of cold water temperature and also the mass flow rates of cold and hot water. This compact heat exchanger can be used for cooling purpose of electronics device like silicon chip which would be used for microprocessor. In order to cool down silicon chip, it is kept in place of hot fluid plate. Cooling of silicon chip is required to prevent from damage and subsequently failure. The heat exchanger is designed for obtaining 10°C of hot fluid.

Optimization of Machining Parameters in CNC Turning Using Firefly Algorithm

Abstract— now a day’s machining is done through various automated machines. One of the widely used machines is CNC. Even though the automated machines are used, the quality of the work is determined by parameters used. The cutting parameters of the CNC machine determine the productivity, surface finish, machining time and other qualities of the product. This study involves the optimization of those cutting parameters. In order to get optimized CNC parameters for a specific tool-work combination, Firefly Algorithm (FA) is used to compute the best parameters based on the experiments conducted on a CNC Turning center. The three cutting parameters are cutting speed (V), feed (f), and depth of cut (d). The practical constraints have been considered during both practical and experimental approaches.  The result reveals that FA is very well suited in solving parameters selection problems.

#Ijsrd : Influence of Metal Temperature on Strength of Rolled Steel Product

#Ijsrd :
Influence of Metal Temperature on Strength of Rolled Steel Product

Abstract—Rolling is extensively used metal forming process. Almost 90% of cast iron or steel products pass through rolling process at least once in its life cycle. Rolling products are most extensively used in daily life. Use of these products can be seen in bridges, towers, leaf springs, boilers, constructional structural parts and also in daily life products like knives pipes etc. In today’s era, quality of products is one of most important factor considered for its use. Quality of a product can either be controlled or improved by changing in composition or by using heat treatment processes.  In rolling products composition is not only the factor which improve the quality of product but temperature plays a vital role in maintaining and improving quality. By changing temperature of rolling we can change grain structure and its mechanical properties without changing its composition.

Performance of Multiple symbol representation with clipping scheme for PAPR reduction in OFDM systems

Abstract :

OFDM is one of the multicarrier modulation technique used in various communication systems. The major problem one faces while implementing this system is the high peak to average power .For an efficient OFDM system this PAPR should be low. In this paper a hybrid PAPR (peak to average power ratio) reduction technique for the OFDM (orthogonal frequency division multiplexing) signal which combines a multiple symbol representations method with a signal clipping method is proposed. In multiple symbol representations alternative signaling points are used to represent one symbol and PAPR is further reduced with the clipping scheme. The performance of the hybrid scheme is compared with the partial transmit sequence which is one of the other PAPR reduction scheme. In partial transmit sequence the input data is divided in to disjoint blocks transformed in to time domain sequence and rotated by phase factors. Theoretical analysis and simulation results validate that the proposed scheme has the ability to provide large PAPR reduction, low bit error rate. Performance analysis is also done with the partial transmit sequence scheme.
