GOHCM has been used to segment the satellite image. Image segmentation is the process of dividing pixels into homogeneous classes or clusters so that items in the same cluster are as similar as possible and items in different cluster are as dissimilar as possible. The most basic attribute for segmentation is image luminance amplitude for a monochrome image and color components for a color image. Since there are more than 16 million colours available in any given colour image, it is difficult to analyze the image on its entire colour. Hence colour image is converted to gray scale. Genetically Optimized Hard C Means (GOHCM) has been used for segmentation. Depending on the spectral value, the pixels are classified as urban area, bare soil, forest & vegetation and water regions by GOHCM.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"1 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115311482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reverse supply chain involves the movement of used products from the customer to the upstream supply chain for possible recycling and reuses. It has been found that reverse supply chain should be part of supply chain integrated as it can contribute to lowering overall costs and meeting environmental regulations. The paper aims at contributing the explicit formulation of quantity of returned products by the consumer and location of collection centre based on the product life cycle of consumer electronic products which is said to be having minimum obsolesce rate. The logic behind the formulation of the quantity of products collected from the consumers is based on capturing the willingness of the consumer to return the products. Selecting a facility location, in most of the real world applications, is a complex process involving multiple facilities, multiple sites, multiple criteria and multiple stages. The transportation cost can be reduced by effective location of collection centre. The second part of the paper aims to efficiently assist the decision makers in determining the “most appropriate” collecting centre location using multi-criteria decision making model.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"119 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123556472","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Genitha, St. Joseph’s","doi":"10.1109/RSTSCC.2010.5712813","DOIUrl":"https://doi.org/10.1109/RSTSCC.2010.5712813","url":null,"abstract":"Super resolution mapping is a set of techniques to increase the spatial resolution of a land cover map obtained by soft classification methods. Linear spectral unmixing have been developed to estimate the class composition of image pixels, but their output provides no indication of how these classes are distributed spatially within the instantaneous field of view represented by the pixel. The use of a Hopfield neural network to map the spatial distribution of classes more reliably using prior information of pixel composition determined from linear spectral unmixing was investigated. The output from the linear spectral unmixing which is a set of area proportion images for each land cover class is given as input to the HNN. The network converges to a minimum of the energy function which is defined by the goals and constraints of the super resolution mapping task. The minimum of the energy of the network represents the best guess map of the given satellite image. The technique was applied to both real and simulated Landsat images, and the resultant maps provided an accurate and improved representation of the area under study. The Hopfield neural network represents a simple, robust, and efficient technique, and results suggest that it is a useful tool for identifying land cover targets from remotely sensed imagery at the subpixel scale.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"123 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127594932","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

OBC must be designed in such a way that each subsystem should be controlled and monitored by the OBC of the satellite. It is a very important task to choose a microcontroller for OBC in order to make the Sathyabama nanosatellite efficient and powerful in all situations.

For images with textures, the high frequency wavelet coefficients are likely to become significant after several code passes of SPIHT, which degrades the coding performance. The basic flaw that wavelet transform exhibits, is its inability to represent edge discontinuities along curves. Less number of coefficients is required in compression process but several wavelet coefficients are used to reconstruct edges properly along the curves. This is due to the reason that in a map of large wavelet coefficients, edges repeat at scale after scale. There was a need of a transform that handles two dimensional singularities along the curves sparsely. This led to the birth of new multi-resolution curvelet transform. Curvelet basis elements possess wavelet basis function qualities but these also oriented at a variety of directions and so represent edge discontinuities and other singularities well than wavelet transform. In the proposed method, a curvelet transform of an image is taken and selected all level curvelet coefficients information. Then, it has been applied with SPIHT encoding. The SPIHT encoded output is stored as a bit stream. Run Length Encoding has been applied to the bit stream. It produces further compressed bit stream. Then run length decoding and SPIHT decoding have been applied and inverse curvelet transform has been taken to reconstruct the image. Images of different sizes have been tested in the experiment and the results are listed in the tables.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"11 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116766434","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thirty five bacterial isolates were isolated from textile dyeing industry effluents. Proficient and rapid dye degradation was identified in thirteen isolates. Microbial consortia were developed on the basis of dye degrading competence of the strains. Nearly 60%–95% degradation was achieved in less than about 72 h in these isolates tested on individual dyes. Promising results were obtained with mixed dye concentration. The dye concentration, pH, temperature and time of degradation were optimized. 16S rRNA gene amplification was carried out for the sequencing and identification of these strains. TLC, HPLC, FTIR and GC-MS analysis were carried out to confirm the presence of aromatic amines and to aid the data supporting the course of degradation. As identified from the analyses, the final products of AB113 degradation were Metanilic acid and Peri acid, the latter was seen to disappear after 72h of degradation.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126067333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It provides a new monitoring and control capability for monitoring the borders of the country. Using this concept we can easily identify a stranger or any object crossing the border where the army cannot reach in regular. Using the satellite communication and GPS tracking the area will be identified. By Object identification system we will be able to get the pictures of that particular area where the strangers has come as well as the details of objects or people who are present there. And later the metal detecting sensors and bomb detection signals will detect the existence of explosives and weapons(metals) with them. The border area is divided into number of nodes. Each node is in contact with each other and with the main node. The noise produced by the foot-steps of the stranger is collected using the sensor. This sensed signal then sends appropriate signals and the frequency measured by that sensor to the main node. Thus the stranger is identified at the main node. Hence it is reasonably faster. On a global scale, WINS will permit monitoring of land, water, and air resources for environmental monitoring. With this we will be able to identify the objects and the movement, direction of their movement and the kind of metals they have. After discussing with the military authorities we will be able to plan the actions to be taken against them. Presently the Indian government is planning to implement the same technology for tracking the vehicles with in the country which carry illegal commodities ( like government issued sugar , rice to be distributed among masses but send to other states without legal permission). The vehicles which carry explosive materials for industrial purposes can be tracked. The missing vehicles during transportation due to various reasons(terrorists attacks) can be easily identified.","PeriodicalId":254761,"journal":{"name":"Recent Advances in Space Technology Services and Climate Change 2010 (RSTS & CC-2010)","volume":"57 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2010-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128156157","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
