Analysis of DVR Performance for Voltage Flicker Mitigations In Distribution System Using Fuzzy Logic As A Controller[ ]


Power Quality problem is an occurrence as a nonstandard voltage, current or frequency that results in a failure or mis-operation of end user equipment. The steady-state PQ characteristics of the supply voltage include surges and spikes, sags, harmonic distortions, and momentary disruptions. Voltage sags and swells are the common events on the electric power network. These problems can be mitigated with voltage injection method using custom power device, Dynamic Voltage Restorer (DVR). In this paper we design a Dynamic Voltage Restorer (DVR) which is utilized for power quality improvement. Here we propose two control techniques which are the Proportional Integral (PI) Controller and Fuzzy Logic (FL) Controller. Results of both the controllers are assessed to know which the best power quality solution is.

Handwritten Tifinagh Character Recognition Using Baselines Detection Features[ ]


We present in this paper a system of Amazigh handwriting recognition based on horizontal and vertical baselines detection features. After the character image preprocessing, the horizontal and vertical baselines of the character are estimated. Parameters such as baselines are used to derive a subset of baseline dependent features. The symmetry of the amazigh characters with horizontal and vertical baselines is better taken into account. Thus, these features are related to the densities of pixels and are extracted on binary images of characters using the sliding window technique. Finally, a multilayer perceptron is used for character classification. Experimental results using AMHCD database demonstrate the efficiency of the proposed system.

Child sex Ratio: Variation among SCs, STs and Non-SCs & STs Maharashtra: A Case Study[ ]


Changes in Child Sex Ratio are a direct reflection of the socio-economic and cultural patterns of the society, especially its attitude towards the girl child. As per Census 2011, on the one side almost all other indicators like literacy, growth rate, life expectancy, and overall sex ratio have shown a positive trend, while on the other side Child Sex Ratio presents a contrasting picture. After Jammu and Kashmir, Maharashtra has shown the greatest decline in Child Sex Ratio from previous census, by 30 points. And also from 1991 the decline in Maharashtra is continuous. Though this very state is considered as one of developed state of India, why there is such a trend is really putting a question in its development perspective. In this paper it will be strived to find out as to why in spite of highly urbanised characteristics, good literacy rate, and higher per capita income than national average; Maharashtra is suffering from lowest condition of female position.

Coastal aquifer vulnerability evaluation of Bonny Island, Niger Delta, Nigeria[ ]


The objective of the study is to evaluate the hydraulic characteristics of the aquifer confining layer (aquitard) in Bonny Island in view of the possibility of surface pollution due its large reserve of crude oil and natural gas and companies with industrial plants. The investigation involved boring of six boreholes to a depth of 30metres using dismountable percussion rig. The field data were obtained from six hours pumping test conducted on the boreholes at a constant discharge rate of 32.5m3/hr. (780m3/day). The De Glee method for steady state drawdown in an aquifer with leakage from a confining layer (aquitard) was adopted for the analysis of data and determination of hydraulic characteristics of the aquifer and confining layer. The permeability values of the confining layer vary between 9.55x 10-4 m/day and 1.33 x 10-2 m/day with an average value of 5.61 x 10-3 m/day while the permeability values for the aquifer vary between 4.83 x10-2 m/day and 103 m/day. The transmissivity values of the confining layers vary between 9.55 x 10-4 m2/day and 2.13 x 10-1m2/day with an average value of 5.39 x 10-2 m2/day and between 8.21 x 10-1m2/day and 4.22m2/day for the aquiferous zone. The values for the aquiferous zone are high, suggestive of a highly transmissible aquifer in the area. However, the average transmissivity value of the confining layer in borehole No3 is relatively high, indicating the possibility of occurrence of leakage especially when there is influence of gravitational and capillary forces on the moisture movement of the underlying soil through the pore spaces. The leakage factor values vary between 1.00m and 15.0m for confining layer. The hydraulic resistance values for confining layers vary between 9.39 x 102 day and 3.32 x 103day. Although, the permeability and transmissivity of the confining layers are low, the capacity of the layer to transmit water through leakage is sufficiently high especially within the location of borehole No3.

Structural, Transport and Optical Properties of Nanostructured Vacuum Evaporated Bi2Se3 Thin Films[ ]


Thin films of bismuth (III) selenide were deposited thermally onto amorphous glass substrates at a pressure of 10-5 torr. X-Ray diffraction analysis was used for identification of the material obtained. Surface morphology of the films was determined using scanning electron microscope (SEM) and atomic force microscope (AFM). Optical, electrical and photoluminescence properties of the films were investigated. According to the resistance–temperature measurements, Bi2Se3 thin films are typical semi-conducting materials with calculated activation energies of 0.031095 – 0.07664 eV and the majority charge carriers are electrons. As-deposited films are characterized with band gap energy of 1.4 - 2.25 eV. Fermi energy was evaluated as 0.0784 to 0.0272 eV and absorption coefficient was found to be 0.173 – 0.059. The emission peak at 598.35 nm of Bi2Se3 attributed the edge emission to transitions associated with donor/acceptor exciton. The peak observed at 671.48 nm shows reduction in band gap. So, this emission can be identified as radiative decay of free exciton of Bi2Se3.

Surface and dispersion properties of dodecanol and tetradecanol based glucoside surfactants[ ]


The sugar based alkyl polyglucosides have been synthesized from fatty alcochols and dextrose on laboratory scale to find the optimum molar ratio of the paratoluene sulfonic acid catalyst for the synthesis in lower reaction temperature and pressure. The chemical structures and purity of the synthesized compounds were confirmed by using fourier transform infrared spectroscopy and nuclear magnetic resonance spectroscopy. The surface and interfacial properties like critical micelle concentration, free energy of micellization, surface excess concentration and surface area demand per molecule were determined. These sugar based surfactants have been found to exhibit good surface tension, emulsion stability, foaming and wetting power. A new approach through nephelometric measurements has been followed to measure the dispersion power and the synergy with sodium dodecylglucosides. A good amount of synergism was found between the alkyl polyglucosides and the anionic sodium dodecyl surfactant. Biodegradation studies showed that the primary biodegradability of the synthesized surfactants was above 80%.

Representation of spatial proximity for various spatial data using Geometric methods[ ]


Co-location pattern is the subsets of Boolean spatial features whose instances are often located in close geographic proximity. Representa-tion of proximity in geospatial data using conventional data models is not consistent. Neighbourhood is a major challenge and key part of spatial co-location pattern mining. Neighbourhood may be defined using topological relationship, metric relationship and combination of both. In most of the co-location mining, the neighbourhood was defined by user. In this paper, we are proposing Delaunay triangulation approach to model the neighbourhood between the objects. Delaunay triangulation is a structure representing the neighbourhood of objects in a succinct and unambiguous manner [7]. This approach eliminates the parameters from the user to define the neighbourhood of objects and avoid multiple test and trail repetitions in the process of mining. A Delaunay triangulation based co-location mining algorithm is developed to mine co-location patterns from complex spatial data.

Intelligent Voltage Instability Detector Based on Phasor Measurement Units[ ]


A neural network based voltage instability detector is proposed in this paper utilizing wide area monitoring system and the measured angle of the installed Phasor Measurement Units (PMUs). Voltage instability is considered one of the critical problems that severely affect the electric power quality. The system which suffers from voltage instability can be easily exposed to fast failure due to voltage collapse. A proposed neural network based voltage instability detector is introduces. This detector depends on the bus voltage angle which is measured by the installed PMUs. A developed Feed-Forward Neural Network (FFNN) is designed and trained. It consists of one input layer with five neurons, two hidden layers, and one output layer. The two hidden layers consist of twelve and nine neurons respectively. The output layer consists of one neuron. The main advantage of the smart developed system is that, it can detect the voltage instability of the whole power system buses in the same time. The developed proposed system is tested on 14 bus IEEE system. The 14 bus IEEE system is simulated using MATLAB to get the system load flow results. Furthermore, the effect of different loading conditions is applied to the simulation system to get their corresponding bus angles values. About 1000 different studied cases are held for different loading values with different power factors on different buses. The results of these cases are tab-ulated, normalized and processed using the ANN. The ANN is trained by the third of these cases. The other values are used to test the performance of the developed system. The results of ANN are analyzed and considered to be satisfactory because of the high accuracy and reliable operation.

Multiple Face Model Recognition of Hybrid Discrete Wavelet Transform and Density Based Score fusion Technique under Uncontrolled Illumination Variation[ ]


A facial recognition system is one of the biometric applications for automatically identifying or verifying a person from a digital image or a video frame from a video source. Mostly it is used in security systems and can be compared to other biometrics such as fingerprint or eye iris recognition systems. Now a day’s face recognition system is recognize the face using multiple-views of faces, for detecting each view of face such as left, right, front, top, and bottom. This face recognition system for large-scale data sets taken under uncontrolled illumination variations. The proposed face recognition system consists of a novel illumination-insensitive preprocessing method, a hybrid discrete Wavelet Transform (HDWT) for feature extraction and Density based Score Fusion Technique for matching. First, in the preprocessing stage different stages are followed like Gamma Correction, DOG(Difference of Gaussion)filtering and contrast equalization which transforms, a face image into an illumination-insensitive image, Then, for feature extraction of complementary classifiers, multiple face models based upon HDWT are applied. To do the feature extraction this system uses DCT and DCT Wavelet transform to generate the feature vectors of the query and database images. Euclidean distance is used as similarity measure to compare the image. Finally, to combine scores from multiple complementary classifiers, a log likelihood ratio-based score fusion scheme is applied. The proposed system uses the ORL face database which has 10 views of 40 people under various environmental variations such as illumination changes, different poses, and time elapses. Using ORL database the computational time require for the system is 0.3264 msec to 0.9672 msec which is less as compare to FRGC database that is 1.0234 msec to 2.0045 msec.

Prioritizing and Optimizing the Test Cases during Regression Testing[ ]


Software testing is one of important phase of the software development life cycle. The software is tested using the test cases. Test cases form the building blocks of the testing process since they get into the core of the source code to find out the faulty code. Test cases are generated by considering the set of input values and their expected outputs. This expected output is again compared with the output after feeding the same values to the software under test. If the expected output is same then the software is working right else there is some problem. After testing the entire software if any change is made to the software the system is tested again which is known as regression testing. To reduce the bulk during regression testing tester need to prioritize and optimize the test cases to yield quick and appropriate results. The paper proposes an approach to optimize the test cases and providing efficient output as compared to the previous approach

Control System Design to Automate 100KV Impulse Generator[ ]


This paper is basically the practical study of converting manually operated impulse generator to automatic generator. Ever since 1970 (when the High voltage lab of UET Lahore, Pakistan was constructed) most of the equipment in this lab has been operated manually. In this Lab, we have two impulse generators with capability of 100 and 500 kilo volts which are used for testing purposes. Both of these use the same mechanism for Impulse generation. In this paper a design is proposed to automate the whole working of the Impulse generator (100KV) for which we used Arduino Board which is coded such that the operator has to insert desired impulse voltage through the computer and the rest of the process will be done by the system itself. We used LabView Simulation tool for coding purpose. All coding is in graphical coding environment.

STUDY OF TYPE-II SUSPENSIONS WITH MORINGA OLEIFERA & ALUM COAGULANTS USING SETTLING COLUMN ANALYSIS[ ]


A study is carried out in a specially designed two settling columns to study effect different parameters on Type-II suspensions namely different diameter of settling column, different initial turbidity samples, and the different coagulants used for effective sedimentation. The optimum dosage of coagulants such as Alum, Moringa Oleifera, and blend of Alum and Moringa Oleifera coagulant is determined by conducting jar Test. Experiments are carried out in the settling columns with the optimum coagulant dosage for three different initial turbidities such as 100 NTU, 400 NTU, and 900 NTU showed that the coagulation with blended coagulant Alum & Moringa Oleifera is better than Alum. It is observed that for no coagulant and with all the coagulants, as the initial turbidity increases the percentage removal efficiency also increases. And for the larger diameter settling column, the removal efficiency is more as compared to the smaller diameter of the settling column.

E – Learning: Usage among Indian Students[ ]


Education through internet is becoming one of the most domineering forms among all other forms of education. A lot of effort is being put in to improve the quality of learning and to improve the relationship among learners and their teachers. Advanced development in the field of virtual education relies on the technologies being used on the internet. E-learning has become very popular in western countries in the past few years but developing countries like India have not yet been able to keep pace with their western counterparts as far as adaptation to such a concept is concerned. Keeping this scenario in mind the authors in this work have tried to find how do the students of technical courses in the higher education in North India use this new learning methodology and how do they react to it. It is in this context that this paper analyzes the usage of e-learning tools by these students of technical courses. It brings out the response analysis of the same set of students (those who use traditional learning methods only as well as those who, in addition, use e-learning methods) on the issues about the role of e-Learning in their studies.

Non-Linear Carry Select Adder Based Enhanced Wallace Tree Multiplier Structure[ ]


A multiplier is one of the key hardware blocks in most digital and high performance systems such as FIR filters, micro processors and digital signal processors etc. Deign of a high performance and high-density multiplier is presented. This multiplier is designed by using the Wallace tree structure with pipelining the Carry Select Adder (CSLA) provides a good compromise between cost and performance in carry propagation adder design. A Non-Linear Carry Select Adder (Square root carry select adder) using RCA is introduced but it offers some speed penalty. However, conventional CSLA is still area-consuming due to the dual ripple carry adder structure. In the proposed work, generally in Wallace multiplier the partial products are reduced as soon as possible and the final carry propagation path carry select adder is used. In this paper, modification is done at gate level to reduce area and power consumption. The Modified Non- Linear Carry Select-Adder (MCSLA) is designed using Common Boolean Logic and then compared with regular CSLA respective architectures, and this MCSLA is implemented in Wallace Tree Multiplier. This work gives the reduced area compared to normal Wallace tree multiplier. Finally an area efficient Wallace tree multiplier is designed using common Boolean logic based Non-Linear carry select adder. This work gives the performance of the Wallace tree multiplier in terms of area, delay and their products may be implementing in Xilinx FPGA.

These simulations consider atmospheric wind forcing, nonlinear wave interactions, and frictional dissipation, and they output statistics describing wave heights, periods, and propagation directions for regional seas or global oceans. forecast has been a key area of investigation and if certain methods can be plotted in order to help in improvement of the forecast it would be salutary to the development in this direction.

Quality of Work-life Of The Employees In Selected Information Technology Companies With Reference To Chennai[ ]


As a result of dynamic changes in work environment, the employees in Information technology companies are greatly affected in quality of work life (QWL), it was seen as the latest revolution in Information Technology (IT) sectors that was taking place in the relationship between employees and work. The focus of this paper concerns a study of the quality of life for the employees at work in the Information Technology companies. The quality of work life (QWL) is a wide term covering an immense variety of programme, Techniques, theories and the management style through which organization and jobs are designed so as grant employees more autonomy, responsibility and authority than is usually done. A high quality of work life is essential for the organization to continue, to attract and retain employees (Sandrick, 2003). The aim of this paper is to determine the factors affecting quality of work life of the employees in the Information Technology (IT) companies and to study the relationship between the satisfaction and performance level with the quality of work life (QWL). In the present study the investigator has chosen the Information Technology (IT) companies in and around of Chennai, based on the interview with the employees in the organization, a pilot study was conducted in the total sample (N = 60 ). The factor contribute to quality of work life includes Work relate pressure, Leadership behaviour description, Work life balance, Management Policies, Opportunity to develop and growth, Job security, Adequate and fair compensation, Inter- personal relation and Work culture. The information collected from the survey will be used to develop the quality of work life (QWL) of the employees in the Information technology companies.

Towards the Development of a Vertical Offshore Reference Surface (VORS) for Seamless Bathymetry in Nigeria[ ]


A vertical offshore reference surface is a unified reference surface that is able to transform different datasets from the ellipsoidal to tidal datums such as (MSL, SST, MHWS, MLWS, LAT, HAT, etc.) and bring these to a common epoch, ellipsoid (GRS 1980) and ITRF reference frame. By unifying surfaces, heights (depths) can be converted from one vertical datum to another. This research discusses the impact of developing a methodology that will enable the transformation amongst the various vertical reference surfaces to support the modelling of data across the land-sea interface in the coastal waters (12nmi) of West Africa particularly, Nigeria. A methodology for use in the Nigeria is proposed after a review of common applied models. The principal challenge to the achievement of such a separation model is the difficulty in modelling and integrating datasets across the land-sea interface. This is prominent, where a homogenous and consistent vertical datum does not exist (absence of a geoid model), lack of tide gauges data along the coastline, hydrodynamic tide model and offshore Permanent Service for Mean Sea Level (PSMSL) tide stations. This research will therefore evaluate the impact of developing a vertical offshore reference surface and proffer solution towards mitigating the inherent challenges.

Application of Frontier Production Model to Cocoa Farming in Surulere Local Government Area of Oyo State,Nigeria[ ]


This study applied stochastic production to determine the technical efficiency of cocoa farmers in Oyo State, Nigeria. A total of seventy respondents was interviewed .Primary data was used with well structured questionnaire. The descriptive analysis showed that a large proportion (58.6%) of the cocoa farmers had formal (primary) education. It also revealed that farm size and family labour have positive and significant relationship with income of the farmers. The cost of chemical and implement have significant but negative relationship with income of the farmers. Inefficiency estimates showed that years of schooling and farming experience reduce the inefficiency of the farmers, while age of the farmers, family size and age of the farm increase the inefficiency of the farmers. The mean technical efficiency of the farmers is 54 per cent. The implication of this result is that any effort aimed at increasing years of schooling and farmers experience will increase the technical efficiency of the farmers. This study therefore recommends mass literacy campaign in the study area in order to increase the technical efficiency of the farmers.
