This paper focuses on the evaluation of the impact of Unified Power Flow Controller (UPFC) on available transfer capability (ATC) enhancement through optimal location of UPFC. Placement of FACTS controller may be quite effective for enhancing the ATC of power system due to the capability to improve line voltage and control power flow through lines. Technical merits of UPFC technology on ATC boosting are analyzed. The application of this paper lies within the new deregulation of power systems where a great deal of emphasis has been put on transmission open access, leading to more efficient utilisation of the existing facilities. The effectiveness of the proposed method for the placement of UPFC in voltage stability margin enhancement has been validated on a IEEE-14 bus system.


This paper presents an investigation of active and reactive power controller to control voltage and frequency for an isolated induction generator driven by a wind turbine, supplying 3-phase 4-wire loads. The control strategy is based on the indirect current control of the VSC (voltage source converter) using a frequency PI controller. The proposed controller consists of three single-phase IGBT (Insulated Gate Bipolar Junction Transistor) based VSC, which are connected to each phase of the induction generator through zig-zag transformer and a battery at their DC link. The controller has the capability of controlling reactive and active powers to regulate the magnitude and frequency of the generated voltage. The proposed isolated system is modeled and simulated in MATLAB using Simulink and Power System Block-set toolboxes to verify the performance of the controller.


Bug report is a report which contains the information about the defects in the system or in the software. Generally, bug report contains the issues written by the wide variety of reporters, with different levels of training and knowledge about the system being discussed. Bug tracking systems are made to manage bug reports, which are collected from various sources. These bug reports are needed to be labeled as security bug reports or non security bug reports, since security bug reports (SBRs) contain more risk than non-security bug reports (NSBRs). In this paper we are using Naive Bayes classifier to classify the bug reports. With naive bayes classifier, feature subset selection method such as Gain Ratio is applied to rank the attributes of the dataset. Gain Ratio is utilized as an iterative process where we select smaller sets of features in incremental manner. Result prove that the classification accuracy is high for attributes having high gain ratio and low for attributes having low gain ratio.


In this paper, Laplace decomposition algorithm (LDA) is introduced for the approximate solution of the system of homogeneous linear partial differential equations. The technique is described and illustrated with some numerical applications. The results assert that this scheme is rapidly convergent and quite accurate by which it approximates the solution using only few terms of its iteration scheme.

In the present investigation, a steady-state mathematical model is developed for a typical four stage Industry. Each stage of the sequence is composed of chemical additions and mixing, reaction in a reten-tion tower, and washing. Unit operation models were formulated using mass balances on liquor, fibres, kappa number, chemicals and COD based on the assumption of perfect mixing and quasi steady-state. The COD is used in this paper as an indication of the amount of effluent coming out from four bleaching stages. COD measurement of bleach plant effluent separately is not a routine mill measure-ment; so COD is calculated in the basis of correlation of COD given by Anjana . In order to validate the model, the simulated results were compared the literature data; a good agreement between the simulation results with the literature data is achieved. In the case studies, the optimization of the process variables are performed in which the effects of operating temperature, residence time, consistency, bleaching liquor flow rate and the wash water flow rates in the washers are studied.


Sign language recognition will be a boost to the hard hearing and deaf people. It is a topic of current research in Computer Science and Engineering field. Deaf people are not able to use the computers and other hand held devices as it is very difficult for them to interact with such devices. So, a lot of research is going on to help them in this area. Either no standard database or no system is available to carry research in this area in India for them. In this research paper we developed a system for hard hearing and physically impaired persons. Here we presented a framework about Indian Sign Language (ISL) with international standards.


MANETs can manage dynamic infrastructure and can stay active rapid changes in the network topology. The one of the key challenges in deploying Mobile Ad-Hoc Networks is routing with scalable and robustness. The objective of this paper is to create of the different mobile ad-hoc routing protocols, and to survey and compare representative examples for every classification of protocols. In this paper we compared three types of routing protocols i.e. pro-active, reactive and hybrid. In order to operate the Ad-hoc Networks as efficiently as possible, appropriate on-demand routing protocols have to be incorporated, to find best effective routes between source to destination. In this paper we provide an overview of a wide range of the existing routing protocols with focused on their characteristics and functionality. This paper focus on the survey of re-active (on-demand), proactive (table-driven) and hybrid routing protocols like AODV, DSDV and ZRP. Further this paper will help the researchers to get an overview of the existing protocols and suggest which protocols may perform better with respect to varying network scenarios.
