Construction industry requires a highly accurate planning, scheduling and management of the process of the project which can facilitate the overall optimization of the cost, time and resources. The traditional system of using of AutoCAD drawings, MS Project andPrimavera for scheduling does not satisfy the clients in making them understanding the project status and also find time consuming. Hence, an efficient method is proposed mthis study implementing Geographical Information System (GIS) as a platform to link the plan of building and its corresponding schedule of executing the construction of building. GIS is relatively an emerging field for managing the spatial and the non-spatial data. The aim of the study is intended to demonstrate methodology of creating the GIS based 4D Model for optimization and real time monitoring of the project. The plan of the building drafted using the drafting software (AutoCAD) and the corresponding schedule of the building generated by Project Management Software (MS Project) were interlinked using GIS platform. This enables the planner to get a clear picture in the planning stage and better control for the progress of the work in the most appropriate manner rather than the conventional methods of controlling the progress of the work with the help of management software. GIS based enclosure also paves the way to include the non-spatial information like bill of quantities, labour requirement, safety recommendations, etc. and can be stored as a tabular form for the corresponding drawing. A case study of one storey residential building at Thangam nagar in Erode, Tamilnadu, India has been selected for the study. © Medwell Journals, 2012.

Dams and other water-retaining structures are normally designed to serve the basic needs of the humans besides generation of power and irrigation. These structures serve for a long period. But, the environmental effects like natural and manmade disasters cause distress in the form of cracks and fissures. The hydrological and structural views are taken into account for the present study on the effect of damage or crack. A typical profile of a retaining structure is chosen and a detailed numerical study using finite elements is carried out to assess the effect of a) location of crack on the boundary or inside the domain b) size of crack and c) performance changes in seepage levels. Different service considerations like full storage and partially full, were taken into account. Contour curves are developed to show the effects of crack. % variation in velocity contours due to seepage and deformation are discussed. © Research India Publications

In the water retaining structure, seepage through the body wall and foundation plays a major role in the failure of structures. To design any kind of structure for proper retaining, the effect due to seepage should be considered widely. In this paper, % of increase in arrested seepage is arrived from various analyses. Compressive strength of nano silica, nano alumina and carbon nano tube is found out by the experiment and Elastic modulus is calculated. Stress analysis is carried out with analysis software 3D SOLID WORKS. The critical location of the crack is noticed for various service conditions like water filled for full height (hd), more than half height (0.75hd) and half height (0.5hd). The seepage analysis is carried out on the basis of two-dimensional Laplace equations. The partial differential equation (PDE) Toolbox in MATLAB, by the method of finite element method (FEM), provides a powerful and flexible environment for the seepage study. Values of the velocity contours are recorded for various sizes of the crack at the critical location before treatment. Later, these cracks are filled with the mortar of nano-silica, nano alumina and carbon nano tube. The values of the velocity contours are recorded again after the treatment. Finally, the percentage increase in arrested seepage is calculated and it is found that carbon nano tube has behaved better. © 2015 Elsevier Ltd. All rights reserved.

In bound applications, the locations of events reportable by a device network have to be compelled to stay anonymous. That is, unauthorized observers should be unable to notice the origin of such events by analyzing the network traffic. I analyze 2 forms of downsides: Communication overhead and machine load problem. During this paper, I gift a brand new framework for modeling, analyzing, and evaluating obscurity in device networks. The novelty of the proposed framework is twofold: initial, it introduces the notion of 'interval indistinguishability' and provides a quantitative live to model obscurity in wireless device networks; second, it maps supply obscurity to the applied mathematics downside I showed that the present approaches for coming up with statistically anonymous systems introduce correlation in real intervals whereas faux area unit unrelated. I show however mapping supply obscurity to consecutive hypothesis testing with nuisance Parameters ends up in changing the matter of exposing non-public supply data into checking out associate degree applicable knowledge transformation that removes or minimize the impact of the nuisance data victimization sturdy cryptography algorithmic rule. By doing therefore, I remodel the matter of analyzing real valued sample points to binary codes, that opens the door for committal to writing theory to be incorporated into the study of anonymous networks. In existing work, unable to notice unauthorized observer in network traffic. However our work in the main supported enhances their supply obscurity against correlation check, the most goal of supply location privacy is to cover the existence of real events. © 2014 IEEE.

This paper presents design and implementations of Delaunay pentangle based fingerprint authentication system for enhancing the security level of biometric template data and withstand local structural change in presence of nonlinear deformity. Feature vector extracted from the Delaunay pentangle is of fixed length and alignment free is less sensitive and more discriminative to nonlinear distortion. Additionally, it is being proposed to construct a unique topology code from each and every Delaunay pentangle to carry through accurate local registration. The proposed topology code not only that helps to carry through accurate local registration and also it improves the security level of biometric template data. The proposed Delaunay pentangle based structure has more attributes and also more discriminating abilities than existing Delaunay quadrangle based structures. Moreover, the proposed system promised two layer of security protection to template data. Experimental results on three public databases of FVC2002 DB1, DB2 and DB3 using Delaunay pentangle based structures with topology code can achieve better performance and higher security level than Delaunay quadrangle based structures. The performance of proposed system certificate low FRR= 1.4%, FAR = 0% and EER = 0.74% on FVC2002 DB2 than existing system. So, this proposed Delaunay pentangle based fingerprint authentication with topology code shows superior performance than Delaunay quadrangle based structures and Delaunay triangle based structures. © Research India Publications.

The demand for need of groundwater goes with descending powers, when compared with the available natural resources to meet the expectations of Agricultural, Municipal and Industrial needs. Consequently, groundwater is being withdrawn from storage and water levels are declining resulting in crop failures, seawater intrusion in coastal aquifers, land subsidence etc. This urges the need of artificial recharge of groundwater by augmenting the natural infiltration of precipitation into subsurface formation by some suitable methods of recharge. This inturns expects the quantitative availability of groundwater in the area, at the earliest, to follow suitable recharge methods. This rapid determination is found possible only when Remote Sensing and GIS approaches are applied in addition to conventional methods, where time frame is lagging. In this study, Remote Sensing and GIS approaches were used to identify groundwater potential zones in Thirumullaivasal village of Nagapattinam district of Tamilnadu. Various thematic maps were prepared for the factors that influence groundwater such as rainfall, soil type, land use, slope and geology using satellite imageries, toposheets and data from Government and other organizations. Ranks and Weightages were assigned for different categories by devising criterion table and Cumulative Suitability Index (CSI) values were found out using Multi-criterion analysis of the prepared thematic maps through GIS. Based on CSI values, the area was prioritized into different groundwater potential zones for future investigation. © (2012) Trans Tech Publications, Switzerland.

In IC assembling there are numerous issues are caught by testing. In this task mostly concentrating on the transition deficiencies. Test cube merge consolidating methodology is already utilized for discover the transition issues and it will attain to low power by decreasing switching transition. Presently in this undertaking proposed two methods for transition faults named as BS-LFSR and LOC. In BS-LFSR, it will produce the pseudorandom designs with low power. The low power is accomplished by lessened switching transition. In launch off-capture system the low power test patterns are attained with expanding the controllability of flaws. With the assistance of Iscas'89 S27 benchmark circuit test results demonstrates that which method is superior to test merging strategy focused around the power and area estimation © 2015 IEEE.

The increasing use of groundwater for Agricultural, Municipal and Industrial needs revealed that the annual extraction of groundwater is far in excess of net average recharge from natural resources. Consequently, groundwater is being withdrawn from storage and water levels are declining resulting in crop failures, seawater intrusion in coastal aquifers, land subsidence etc. Vagaries of monsoon and indiscriminate development of groundwater often result in declining trend of groundwater levels. This necessitates artificial recharge of groundwater. Any artificial recharge method, for to be implemented, needs a quick result on groundwater availability in the area. This fastest identification is found possible only when remote sensing and GIS approaches are applied as a substitution for conventional methods, where time consumption is more. In this study, remote sensing and GIS approaches were used to identify ground water potential zones in Thennampattinam village of Nagapattinam district of Tamilnadu. The factors influencing groundwater such as rainfall, soil type, land use, slope and geology were considered for study. The thematic maps for the factors were prepared using satellite imageries, topo sheets and data from government and other organizations. Ranks and Weightages were assigned for different categories by devising criterion table and Cumulative Suitability Index (CSI) values were found out using Multi-criterion analysis of the prepared thematic maps through GIS. Based on CSI values, the area was prioritized into different ground water potential zones for future investigation. © Research India Publications.
