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 Source

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. Source

In this study, an interleaved soft switching Boost Converter is used to track the maximum power point of PV array and full bridge inverter is used to stabilize the dc bus voltage. In this method, an interleaved technique is adopted to reduce the current rating of each device. Switching losses are reduced by adapting a zero voltage transition which increases the efficiency of the system. The experimental results are verified using Power SIM simulation software during open loop and closed loop operation. Compared to hard switching technique the results imply that 1% of overall efficiency is improved in this system. © Maxwell Scientific Organization, 2013. Source

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. Source

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. Source
