Change Detection Studies of Sagar Island, India, using Indian Remote Sensing Satellite 1C Linear Imaging Self-Scan Sensor III Data

Abstract: The coastal zone of Sagar Island, India, is subjected to various cyclic and random processes that continuously modify the region. The shoreline and land-use/land cover changes have been studied using Indian Remote Sensing Satellite 1C (IRS IC) linear imaging self-scan sensor (LISS) III satellite data from 1998 and 1999. A comparison between a topomap of 1967 and satellite data of 1999 established that during these years about 29.8 km of coastline was eroded, whereas the accretion is only 6.03 km2. A comparison of satellite data from 1998 and 1999 showed that the island had undergone severe erosion of about 3.26 km2, while the accretion was just about 0.08 km2. Change detection studies based on land-use patterns of the region revealed that the areal extent of mangrove vegetation of the island during 1998 and 1999 was 2.1 km2 and 1.3 km2, respectively. The areal extent of agricultural fields during these periods was 130.4 km2 and 118.6 km2, respectively. These results can be used to develop an inde...

A review on soil–structure interaction analysis of laterally loaded piles

Abstract: Soil–structure interaction plays an important role in the behavior of structure under static or dynamic loading. It influences the behavior of soil, as well as the response of pile under loading. The analysis is highly essential for predicting a more accurate structural behavior so as to improve the safety of structures under extreme loading conditions. The soil–pile system behavior is predominantly nonlinear and this makes the problem complicated. In a laterally loaded pile the load is resisted by the soil–pile interaction effect, which in turn depends on soil properties, pile material, pile diameter, loading type and bed slope of ground. The difficulty in the accountability of the influencing factors necessitates a careful study on soil–structure interaction problem. The analysis became easier with the debut of powerful computers and simulation tools such as finite element analysis software. A detailed literature review on soil–structure interaction analysis of laterally loaded piles is presented in this paper.

Tuning the properties of sprayed CuZnS films for fabrication of solar cell

Abstract: CuZnS is a promising material for solar cells, having mixed structure of CuxS and ZnS. In CuZnS thin films prepared by Chemical Spray Pyrolysis, it was observed that the material can be changed from n-type to p-type and electrical conductivity can be increased by 4 orders by just varying the Cu concentration. Increase in concentration of Cu also leads to decrease of band gap from 3.4 eV to 1.8 eV. Films of high concentration of Cu can be used as good absorber and Cu-poor films as buffer/window layer in solar cells. A bilayer heterojunction photovoltaic device could be fabricated using automated spray machine. Here, CuZnS was the absorber layer and In2S3 was the buffer layer. Using Ag as top electrode, J-V characteristics of the cell was recorded. For the optimum doped cell, the parameters obtained were Voc = 0.451 V, Jsc = 5.47 mA/cm2, FF = 42.2%, and η = 1.04%.
