Water distribution systems constitute a vital part of civil infrastructure. The purpose of a water distribution system is to ensure the supply of water to users at specified demands. The main objective of the research works is to study the exiting water supply system of Bawaliyari village, Taluka Dholera, source of the water and then planning water distribution system using ArcGIS. This paper addresses the use of ArcGIS for mapping and planning water distribution network. GIS based tools will be used for the digitization of village (polygon), water distribution network (polyline) and nodes (point) which are important from the water distribution point of view. Two tools have been used i.e.3D analyst & Spatial analyst for extracting elevation information from Shuttle Radar Topography Mission (SRTM) image at various locations of the village including Nodes’ locations which has been used to create a contour map of the village and there after fixing the location of the Elevated Service Reservoir (ESR). Data generated in ArcGIS such as topography, nodes’ elevation, length of the pipe etc., can be used for designing the efficient and economical water distribution system as they can been readily imported as input files for the hydraulic simulation models like EPANET, Water CAD and Water GEMS as well as the programs like Branch and Loop.

Pages: 477 - 480
In a software industry, many Software development life cycle (SDLC) models are used with a sequence of activities for system designing and maintaining system information. These models are used for the development of large scale software system like waterfall, spiral, prototype and rapid application development model. An empirical study was conducted in 2012 that proposed the many factors for the selection of any software life cycle model. Team size was considered as one of the most important factor in this study. The inter arrival time of software projects in a software industry is unsystematic and allocating the number of workers and resources to these projects sometimes results in most important deficiencies like late delivery of the project, budget overruns and disappointed client. Therefore this review will purpose a model, for the Spiral development process with the use of a simulating tool (Symphony.NET). This model supports in make best use of the development processes by keeping all employees busy, all the time for the software development. For future work, other development models like Prototype, Incremental etc. will be simulated, in order to decide which model is more effective in performance and timely delivery in the software industry.

Third leading cause of unintentional death of total world population is drowning. Mostly, rescue attempts ends in failure mainly because of the due to long search time because of the absence of suitable and affordable aid which helps in searching .Current models of underwater drone are used in ocean are not used in local streams. Main disadvantages of the current models are that, they are designed for high cost, complex design etc. In the analysis it was found that the proposed design withstands the operation conditions of an underwater drone. It achieves stable equilibrium in fully merged condition. And it was found that the drone can achieve a speed up to .9m/s in the flow and work comfortably at a depth of 1km by using fiber glass body. The design also allows the installation of more gadgets like sonar and other devices. In the future application or as an extension of the project the drone can be used for many other purposes like under water exploration, useful tool for fishermen etc.

The test cases are generated manually as well as automatically to test software product. Manual test case generation require more time and cost than automatic test case generation. Automated generated test cases decrease the time and cost of testing process. Nowadays software companies are turning towards automated test case generation. After the generation of test cases, there is need to optimize the generated test cases. For their optimization we will apply artificial intelligence techniques. The genetic algorithm is based on the evolutionary ideas of natural selection and genetics. Genetic Algorithm (GA), a heuristic search algorithm is used for optimization. Here, we will integrate tabu search algorithm with genetic algorithm (GTSA) for optimization the result using an analysis of data.

Pages: 493 - 498
Plain, unreinforced concrete is a brittle material, with a low tensile strength, limited ductility and little resistance to cracking. In order to improve the inherent tensile strength of concrete there is a need of multidirectional and closely spaced reinforcement, which can be provided in the form of randomly distributed fibers. Steel fiber is one of the most commonly used fibers. Short, discrete steel fibers provide discontinuous three-dimensional reinforcement that picks up load and transfer stresses at micro-crack level. This reinforcement provides tensile capacity and crack control to the concrete section prior to the establishment of visible macro cracks, thereby promoting ductility or toughness. The modulus of elasticity of concrete is a very important parameter reflecting the ability of concrete to deform elastically. In addition, in order to make full use of the compressive strength potential, the structures using high strength concrete tend to be slimmer and require a higher elastic modulus so as to maintain its stiffness. Therefore, knowledge of the modulus of elasticity of high strength concrete is very important in avoiding excessive deformation, providing satisfactory serviceability, and avoiding the most cost-effective designs.

Pages: 503 - 511
In this study, the benefits of limestone powder (LP) and marble powder (MP) as partial replacement of Portland cement are established. Furthermore, LP and MP are used directly without attempting any additional processing in the production of self-compacting concrete (SCC). The water to binder ratio is maintained at 0.33 for all mixtures. The examined properties include workability, compressive strength, flexural strength and static and dynamic elastic moduli. Workability of the fresh concrete is determined by using both the slump-flow test, T50 test and the L-box test. The results show that it is possible to successfully utilize waste LP and MP as mineral admixtures in producing SCC. Due to its observed mechanical advantages, the employment of waste mineral admixtures improved the economic feasibility of SCC production on a unit strength basis.

Pages: 512 - 516
There are several methodologies and techniques that already offer hardware and software solutions for computing Fast Fourier Transform (FFT), which have advantages for specific applications. These solutions are developed for running in several platforms, such as GPU, DSP, FPGA and ASIC and they are usually described in C/C++ language or HDL. Implementation intended for reconfigurable logic is usually described in HDL, such as VHDL or Verilog. Different FFT algorithms have been proposed to exploit certain signal properties to improve the trade-off between computation time and hardware requirements. For years the common practice for implementing FFTs has been to run them on a digital signal processor (DSP). But as FPGAs have evolved and have begun to accommodate function specific computing cores, FPGAs are beginning to displace DSP as the optimum FFT solution. In this project the implementation of FFT radix 2 algorithm design of floating point FFT in FPGA is discussed. The VHDL Design was tested using Modelsim measure its performance in term of speed and scalability and also the processor is synthesized on an FPGA to measure the performance parameters such as maximum operating frequency, area and power consumption. Synthesis tool is Xilinx ISE Design Suit 10.1 and FPGA is Sparten III.

Fuel injection pressure is one of the important parameters which affect the performance and emissions in an internal combustion engine. Fuel injection pressure directly effects the atomization of injected fuel which allows for a more complete burn and helps to reduce pollution. The main objective of this work is production of biodiesel from milk scum waste and to investigate the effect of fuel injection pressure on performance and emission characteristics of milk scum biodiesel and its blends. In the present work single cylinder direct injection diesel engine is used to study the performance and emission characteristics at different injection opening pressures of 190 bar, 200 bar and 210 bar. The produced biofuel is blended with diesel (B10, B20, B30, B40, B50 and B100) were tested for fuel properties to use as substitute fuel for diesel engine. The tests were conducted at constant speed and varying loads for different injection opening pressures. The performance parameters evaluated are break thermal efficiency (BTE), brake specific energy consumption (BSEC) and emissions measured are carbon monoxide (CO), hydrocarbon (HC) and oxides of nitrogen (NOx). The results of experimental investigation with biodiesel blends with diesel are compared with that of diesel. From the test results it was found that biodiesel blend B30 at injection opening pressure of 210 bar gives better performance and emission characteristics compared to diesel.

Devanagari is the most popular script in India use by more than 500 million people. The handwriting recognition area has been researched extensively till date, whereas offline recognition of Devanagari script is progressing area of research. This system involves three steps, pre-processing, feature extraction and classification respectively. In the first stage words from input images are normalized. Then, a set of intensity features are extracted from each of the segmented words. Gradient features are extracted from an image Then structure-like features are also extracted. Finally, these features are applied in a combined scheme for classification. Intensity features & Gradient features are used to train a HMM classifier, whose results are re-ranked using structural features for improved recognition rate.
