Abstract : Dynamic voltage restorers (DVR) can provide the most commercial solution to mitigate voltage sag by injecting voltage as well as power into the system. Nowadays, a lot of devices have been developed to mitigate voltage sag such as Dynamic Voltage Restorer (DVR), Distribution Static Compensator (D-Statcom) and Uninterruptible Power Supply (UPS). The efficiency of the DVR depends on the performance of the efficiency control technique involved in switching the inverters. This paper deals with the mitigation of voltage sag, performance of DVR under various DC storage devices and the control techniques of DVR

Authors : Dr. Kavita Shrivastava

Click Here For Abstract

Abstract : The purpose of this article is to suggest one of the many ways in which value education can be incorporated into existing mathematics curriculum and approaches to teaching mathematics. In particular, it will focus on ways in which values education can be enhanced by utilizing a problem-solving approach of the discipline. Presenting a problem and developing the skills needed to solve problem is more motivational than teaching the skills without a context. It allows the students to see a reason for learning the mathematics, and hence to become more deeply involved in learning it. Teaching through problem solving can enhance logical reasoning, helping students to be able to decide what rule, if any, in a situation requires, or if necessary to develop their own rules where an existing rule cannot be directly applied. Human life is also a problem solving game throughout. If a student’s mind is trained to derive logical conclusion in certain situation then he will always be a better equipped person to handle even the toughest situation in a controlled and balanced manner. This article suggests that a problem-solving approach can contribute significantly to the outcomes of a Mathematical education. Problem solving is an important component of mathematical education because it is the single tool which seems to be able to achieve all three of the values of mathematics: functional analysis, logical derivation and aesthetic temperament. Value education in mathematics help students find their rightful place in the world. Value in a Mathematics curriculum add a new dimension to promote an all round personality development of a students and nurtures their academic career in a better way.

Title : Transient Stability Analysis in Micro grids Using P-f & Q-V dot droop controller


Click Here For Abstract

Abstract : Generation is shifting from a centralized power generating facility having large synchronous generators to distributed generation involving sources of smaller capacity. Most of these sources require inverters on the front end while being connected to the grid. Lower available kinetic energy, coupled with less short-circuit current ratio compared to large synchronous generators, compromises the transient stability of the microgrid when isolated from the main grid. Sources in the microgrid use droop control to share power according to their capacity without any form of communication. This paper proposes a novel Q-V dot droop controller for inverters to improve the frequency response of microgrid under disturbances involving large frequency deviations. It also discusses design of various parameters defined for the proposed control. The microgrid, which has two inverters and two synchronous generators, is simulated using Simulink/MATLAB software to test the proposed control strategy.

Title : Security Constrained OPF with TCSC and TCPST

Authors : Ch V Ramachandra Rao, N Sri Harish, Ch Rambabu

Click Here For Abstract

Abstract : In recent years, power demand has increased substantially while the expansion of power generation and transmission has been severely limited due to limited resources and environmental restrictions. As a consequence, some transmission lines are heavily loaded and the system stability becomes a power transfer-limiting factor. Flexible AC transmission systems (FACTS) controllers have been mainly used for solving various power system steady state control problems. However, recent studies reveal that FACTS controllers could be employed to enhance power system security in addition to their main function of power flow control. This paper presents a novel approach to solve an optimal power flow problem with embedded security constraints (OPF-SC), represented by a mixture of continuous and discrete control variables, where the major aim is to minimize the total operating cost, taking into account both operating security constraints, and system capacity requirements. The particle swarm optimization (PSO) algorithm has been used as the optimization tool. The effect on security in the presence of Facts device like Thyristor Controlled Series Capacitors (TCSCs) and Thyristor controlled Phase shifting Transformers (TCPSTs) are analyzed. Simulations will be done on IEEE 30 bus system for a few harmful contingencies.

Title : Investigation on outline of Homogeneous charge compression ignition and its scope of development

Authors : P.V.Ramana, B.Umamaheswar Gowd, D.Maheswar

Click Here For Abstract

Abstract : The homogenous charge compression ignition (HCCI) is a promising new engine technology that combines elements of the diesel and gasoline engine operating cycles. Homogeneous charge compression ignition is another way to develop as an alternative to diesel engines with high efficiency and low NOx and particulate matter emissions to increase the efficiency of the gasoline engine. The attractive properties are increased fuel efficiency due to reduced throttling losses, increased expansion ratio and higher thermodynamic efficiency. With the advantages there are some mechanical limitations to the operation of the HCCI engine. The implementation of homogenous charge compression ignition (HCCI) to gasoline engines is constrained by many factors. The main drawback of HCCI is the absence of direct combustion timing control. Therefore all the right conditions for auto ignition have to be set before combustion starts. This paper describes the past and current research done on HCCI engine. Many research got considerable success in doing detailed modeling of HCCI combustion. This paper aims at studying the fundamentals of HCCI combustion, the strategy to control the limitation of HCCI engine and finding optimum operating conditions for HCCI engine operation. The purpose of this paper is to work on the combustion timing and the engine operating zone for HCCI engines. Four main areas of timing control were identified in an investigation of the available literature: one is the thermal control through exhaust gas recirculation (EGR), and others are variable compression ratio (VCR), variable valve timing (VVT), Fuel mixtures or additives. To investigate HCCI Combustion Process a detail CFD (Computational Fluid Dynamics) approach will be used to limit the drawback of HCCI Engine.

Title : Compensation of Reactive Power and THD Minimization in the Grid Connected Wind Energy System Using Bang-Bang Controller

Authors : Sambasiva Rao Bandreddy, Srinivas Vudumudi

Click Here For Abstract

Abstract : This paper presents the design of VSI based STATCOM for eliminating harmonic currents due to nonlinear load and to compensate the reactive power in grid connected system. Normally Static compensator (SVC) can be used to improve the power quality by reducing the harmonics in the grid current. But it has less reactive power compensation. This is because at a low voltage limit, the reactive power drop off as the square at a low voltage for the SVC.That’s why The Static Synchronous Compensator (STATCOM) is increasingly popular in power quality application. This VSI draw or supply a compensating current from the utility such that it cancels current harmonics on the AC side. STATCOM generates a current wave such that it compensate by cancelling out the non-linear current waveform generated by load. The performance of the wind turbine and thereby power quality are determined on the basis of measurements and the norms followed according to the guideline specified in International Electro-technical Commission standard, IEC-61400. The influence of the wind turbine in the grid system concerning the power quality measurements are-the active power, reactive power, variation of voltage, flicker, harmonics, and electrical behavior of switching operation and these are measured according to national/international guidelines .The STATCOM control scheme for the grid connected wind energy generation system for power quality improvement is simulated using MATLAB/SIMULINK in power system block set. Finally the proposed scheme is applied for both constant and variable linear and non linear loads.

Abstract : A field experiment was conducted in Central Research Station of O.U.A.T, Bhubaneswar, to study the direct and residual effect of Boron on Rice-Tomato cropping system in Inceptisols. Rice crop (Cv. Lalata) was transplanted in sandy loam Inceptisols with a design of RBD, with five levels of Boron (0, 0.5 ,1, 1.5, 2 Kg B/ha) and four replications with recommended dose of NPK. After harvest of Rice, Tomato (Cv. Utkal Kumari) was grown. Rice grain yield and tomato fruit yield was recorded. The samples were collected for nutrient and quality study. Post-harvest soil samples were collected, processed, and analysed for nutrients. The results revealed that rice crop responded to B application by producing more yield in all B treated plots than recommended dose of fertilizer. Highest rice grain yield of 49.44 q/ha was obtained when B was applied @ 1Kg/ha., Whereas residual effect of Boron on succeeding crop tomato was promising with yield response up to 1.5 Kg B/ha. Highest tomato yield 22.14 (t/ha) was obtained in the treatment receiving Boron @ 1.5 Kg/ha with recommended dose of NPK. Boron uptake by rice grain ranged from 10.19 to 52.38 g/ha. Highest Boron uptake in rice grain was found 52.38 g/ha in the treatment of 1Kg B/Ha. Similar trend was also observed in straw. Total Boron uptake increased significantly with increasing dose of B up to 2 Kg/ha., while Boron uptake by Tomato plant was much higher than uptake by fruits. Highest B uptake (336.70 g/ha) by fruit was obtained in the treatment receiving Boron @ 1.5 Kg/ha with recommended dose of NPK. Overall boron uptake was in increasing trend with increase dose of Boron. The quality parameters like Lycopene, Ascorbic acid, TSS and Crude protein were improved in tomato fruits significantly with increasing dose of B application

Title : Thermal Analysis & Operation Performance of Fluidized Ash cooler

Authors : S.V. Thite, S.B. Ingole

Click Here For Abstract

Abstract : Fluidization technique is used frequently in various operating plants. The ash generated in FBB is carrying heat during drain operation. To save this heat energy, as well as to make it safe to handle this ash, Fluidized Bed Ash Cooler (FBAC) is proposed in this paper. In CFBC technology the bed temperature is around 800-900 ºC. To maintain constant, boiler bed height it is necessary to drain the bed once it reaches to the desired limit. Transportation of this drained hot ash is difficult and unsafe unless it is cooled. It is proposed to cool hot ash by the air tapped from the primary air ducting to a temperature at which it can be transported easily and safely by conventional technology. The proposed bed ash cooler can take drained boiler bottom ash at a high temperature from Fluidized bed or Circulating fluidized bed boilers continuously and controllably. Consequently the heat is recovered from the hot ash by air and is fed back to the boiler as secondary combustion air above the fluidized bed in order to avail it for further combustion in the furnace. In this paper, FBAC is manufactured based upon the calculations done taking the actual inputs of ash generation CFBC. Testing of the same is done on site. Results obtained from the field data and the data developed by the distributed control station (DCS) are verified for the desired results.

Abstract : The aim of this work is to study the stick and the boom of an excavator & various forces acting on the bucket. The present review provides brief information about the excavator arm mechanism. Excavators are heavy construction equipment consisting of a boom, stick, bucket on the rotating platform known as the house. In this paper it is proposed to study the concept of finite element method and its application to the excavator arm design. Also various calculations are required to do in the areas where the problem occurs in the excavator. For this purpose many different load conditions have been studied numerically on the original excavator in order to estimate a safety factor and the deformability or flexibility of each component. Failure involves cracking of boom, failure in adaptor and dislocation at the bucket end due to the play in pin joint which is mainly because of digging force. In order to suggest the solution to these problems existing in the Excavator arm, it is necessary to do complete study of the Excavator and failures occurring in it.

The vertebral column usually consists of 24 articulating vertebrae, and nine fused vertebrae in the sacrum and the coccyx. It is situated in the dorsal aspect of the torso, separated by intervertebral discs.The lumbar spine refers to the lower back, where the spine curves inward toward the abdomen. It starts about five or six inches below the shoulder blades, and connects with the thoracic spine at the top and extends downward to the sacral spine. The lumbar vertebrae are the largest segments of the movable part of the vertebral column, they are elected L1 to L5, starting at the top. Bio-CAD has been used to assist in Bio-Medical design and Modeling of images for analysis. In this work Bio-CAD technique along with Canny Edge detection algorithm has been proposed to model and analyze the spine images. To find the correct boundary in noisy image of spine is still a difficult one. The proposed Canny Edge Detection algorithm has been used to detect the boundaries of spine image from the noisy spine image. The performance of proposed technique has been compared. The results show that the proposed Bio-CAD technique performs well and produced the better optimal solution Canny Edge Detection algorithm. This method is robust for all kinds of noisy images without prior knowledge of other properties. The performance of the both techniques was analyzed by calculating the probability error and edge length.

Title : The Efficient Markets Hypothesis (EMH), News and Cointegration: Theory and evidence


Click Here For Abstract

Abstract : This paper revisits the impact of news on the determination of exchange rates. In fact we will be presenting an analysis and discussions for testing the Efficient Markets Hypothesis (EMH) using a news format and using Cointegration methodology. However, before presenting the results some useful points should be considered in order to carry out the analysis of this study. Accordingly, section 2 of this paper gives some restrictions of cointegration techniques when it is used for models that have more than two variables. The variables that we will be using in this analysis are defined in section 3. Section 4 provides the source and period of database used. The test results are given in section 5. The implications of including cointegrated variables will be discussed in section 6, mainly the issues of purchasing power parity, covered and uncovered interest parities. Finally some concluding remarks are drawn up.

Abstract : Face detection and Face Recognition has been regarded as a challenging Problem in the field of computer vision. It has become a new research in the identity authentication. In this paper, we propose two steps (i.e) First Face detection and then Face Recognition. Here Adaptive skin colour modelling is used for face detection and memetic approach for face recognition. Memetic algorithm are also known as hybrid EAs.A combination of global and local search makes MAs a powerful algorithmic technique for evolutionary computing.Facial Features were extracted with Zernike transform, trained and finally selection process is carried out. In this approach, we find results comparatively compared with the existing genetic algorithm.

Abstract : Distributed arithmetic (DA)-based computation is popular for its potential for efficient memory-based implementation of finite impulse response (FIR) filter where the filter outputs are computed as inner-product of input-sample vectors and filter-coefficient vector. In this paper, however, we show that the look-up-table (LUT)-multiplier-based approach, where the memory elements store all the possible values of products of the filter coefficients could be an area-efficient alternative to DA-based design of FIR filter with the same throughput of implementation. By operand and inner-product decompositions, respectively, we have designed the conventional LUT-multiplier-based and DA-based structures for FIR filter of equivalent throughput, where the LUT-multiplier-based design involves nearly the same memory and the same number of adders, and less number of input register at the cost of slightly higher adder-widths than the other. Moreover, we present two new approaches to LUT-based multiplication, which could be used to reduce the memory size to half of the conventional LUT-based multiplication. Besides, we present a modified transposed form FIR filter, where a single segmented memory-core with only one pair of decoders are used to minimize the combinational area. The proposed LUT-based FIR filter is found to involve nearly half the memory-space and 1/ Ntimes the complexity of decoders and input-registers, at the cost of marginal increase in the width of the adders, and additional ~(4N+W)AND-OR-INVERT gates and ~(2N+W)NOR gates. We have synthesized the DA-based design and LUT- multiplier based design of 16-tap FIR filters by Synopsys Design Compiler using TSMC 90 nm library, and find that the proposed LUT-multiplier- based design involves nearly 15% less area than the DA-based design for the same throughput and lower latency of implementation.

Abstract : Corporate branding plays a crucial role in building a sustainable bond between the branded company and its customers. Because consumers’ corporate brand image develops over time, previous experience with a company and its products/services are of particular importance. During recent years, the question of brand heritage and how past, present and future merge to create corporate brand image has gained growing interest in both marketing research and managerial practice. The aim of the present study is to probe the importance of brand heritage on consumer brand image construction based on attitudinal components of brand strength. Using a conceptual model focusing on the antecedents of brand heritage and its effects on attitudinal components of brand strength, we present the methodology and the results of our empirical study based on a PLS-PM approach. The results support the assumption that consumers search for authentic brands with genuine history in an increasingly global and dynamic marketplace. This adds value to Global Economy with reference to Liberization-Privatisation-Globalization Principle in India.

Abstract : Open nature of peer-to-peer systems exposes them to malicious activity. Building trust relationships among peers can mitigate attacks of malicious peers. The present distributed algorithms that enable a peer to reason about trustworthiness of other peers based on past interactions and recommendations. Peers create their own trust network in their proximity by using local information available and do not try to learn global trust information. Two contexts of trust, service, and recommendation contexts are defined to measure trustworthiness in providing services and giving recommendations. Interactions and recommendations are evaluated based on importance, recentness, and peer satisfaction parameters. Additionally, recommender’s trustworthiness and confidence about a recommendation are considered while evaluating recommendations. In the Enhancement work the malicious node will be identified and reported to the monitor. The monitor will verify with the neighbor confirmation and evict the malicious node and also that will give the alert about malicious node to the entire network node.

Title : Optimization of Topology For Multihop Cellular Network Using High Speed Genetic Algorithm

Authors : Preet Kamal, Er. Sunita Rani

Click Here For Abstract

Abstract : Genetic algorithm is used in searching a large state-space, multi-model state-space or n-dimensional surface. A Genetic Algorithm may offer significant benefits over more typical search of optimization techniques. The Genetic Algorithm is a popular optimization technique which is bio-inspired and is based on the concepts of natural genetics and natural selection theories proposed by Charles Darwin. The Algorithm functions on three basic genetic operators of selection, crossover and mutation. Based on the types of these operators GA has many variants like Real-coded GA and Binary coded GA. There are various crossover and mutation methods to accomplish Genetic Algorithm (GA), namely, single point, multipoint, uniform, etc. However, these mechanisms are static in nature. This work presents a new crossover mechanism. The purpose of this concept is twofold; to achieve faster transmission rate. The results indicate that for a linear and a nonlinear objective function, it outperforms all static crossover mechanisms. A new algorithm for efficient relaying topology control is presented to jointly optimize the relaying topology, routing and scheduling resulting in a two dimensional or space time routing protocol. The algorithm is aware of inter cell interference (ICI), and requires coordinated action between the cells to jointly choose the relaying topology and scheduling to minimize the system performance degradation due to ICI. In the presented work, we have simulated a new Genetic Algorithm to model the topology network. On the behalf of results of link graphs, we can conclude that in the case of time it is observed that the new crossover technique is better irrespective of function, threshold, and iterations.

Abstract : Among the proposed alternatives for diesel engines, biodiesel and ethanol have received much attention because they are renewable and readily produced from a variety of feedstocks using proven technology. The physical and chemical characteristics of alternate fuels are very important for its application in diesel engine. The properties of blends have great impact on the injection, atomization, ignition, and combustion properties, as well as cold start, output power, fuel consumption, and emission characteristics of engine. The objective of this paper is to characterize the key properties of diesel-biodiesel- ethanol blends. The properties such as density, viscosity, flash point, pour point, specific heat, heating value, and cetane number of diesel-biodiesel- ethanol blends are measured experimentally and the oxygen content of these blends is estimated theoretically. The diesel-biodiesel-ethanol blends containing 5% rice bran biodiesel and 5% ethanol (B5E05), 10% rice bran biodiesel and 10% ethanol (B10E10) and 20% rice bran biodiesel and 10% ethanol (B20E10) have all properties very much close to that of the diesel fuel.
