These approaches and combinations of them, be it partially or fully, helps in extracting knowledge from huge data sets especially as in geo-informatics. These methods of data mining are quite useful in depicting trends and patterns associated with huge amount of partially correlated data generated at various stations and classifying them based on different variables associated with the process which can also be in a non-linear fashion. These methods are successfully applied individually in various contexts. We suggest that combinations of these approaches when worked upon yield an effective classification of data even in the complicated and distributed field of geo-informatics.</p>2018-06-30T00:00:00+00:00Copyright (c) 2018 Diego Liberatihttps://uniquepubinternational.com/journals/index.php/jet/article/view/57Carbon-Carbon Composites – A Review2022-01-11T14:43:25+00:00Anilas K[email protected]Surendranathan A O[email protected]<p>Carbon-carbon composites (CCC) stand unique in the class of composites as they possess some extra-brilliant properties which the other composites do not have. They combine the advantages of both carbon fibre and carbon matrix such as high specific strength, stiffness and in plane toughness as well as refractory properties like retention of mechanical properties at extremely high temperatures of the order of 3000oC. This has resulted in the exploitation of CCC as structural materials in space vehicles, heat shields, rocket nozzles and aircraft brakes. Properties like biocompatibility and chemical inertness have led to new applications in medicine industry. Carbon fibres may be combined in a wide variety of forms; woven, knitted, braided and filament wound, to provide 1, 2 and multidirectional reinforced composites. The matrix can be a vapor deposited carbon, glassy carbon or coke. Also, the degree and extend of graphitization may be varied considerably, imparting a wide range of thermo-chemical properties of composites. Conventional fabrication techniques like Gas phase impregnation (Chemical vapour deposition (CVD)) and<br>Liquid phase impregnations were employed in the early ages of CCC fabrication. Later on, modifications like liquid phase pre-impregnation (LPI), hot pressing, hot isostatic pressure impregnation carbonization (HIPIC) and isothermal CVI saw the improvement in properties of the fabricated CCC. Advanced techniques like Preformed Yarn (PY) method showed exceptional values for specific strength and fracture toughness. Successful modifications and modern techniques like application of temperature, densification, increasing the number of pitch/resin impregnation cycles, using carbon nano tubes/carbon nano fibres as reinforcements, growing multi walled carbon nano-tubes on woven carbon fibre, fibre architecture modifications, microwave curing, fibre sizing, ultra-high temperature ceramic coating are also reviewed to throw light on how these have improved the important mechanical properties, which make CCC as the “material of future”.</p>2018-06-30T00:00:00+00:00Copyright (c) 2018 Anilas K, Surendranathan A.Ohttps://uniquepubinternational.com/journals/index.php/jet/article/view/58Information Technology in Everyday Life2022-01-11T14:50:51+00:00Zhangissina GD[email protected]Zhangissina AN[email protected]<p>The aim of this paper is to address the effects of Information Technology (IT) in the everyday life. IT is increasingly playing a vital role in the success of everyday life of individuals and shows impact on various sectors such as business firms, organizations, medicines. Every day people use computers for various purposes. Computers are becoming more accessible, in addition, they continue to become more powerful in the processing of information and easier to use. IT and computers will process and store the everyday aspect of the society. How it has a good impact, it also has bad impact on our everyday life. This paper will summarize the key aspects of IT and computers in different domains such as business, medicine, education, science and engineering.</p>2018-06-30T00:00:00+00:00Copyright (c) 2018 Zhangissina GD, Zhangissina ANhttps://uniquepubinternational.com/journals/index.php/jet/article/view/60Separation of Bio-Butanol2022-01-11T15:02:58+00:00Kailas L. Wasewar[email protected]<p>Research to develop an alternative to fossil fuels is the interest of research. Bio-fuels produced from a fermentation process are the alternative to petroleum based fuels. Bio-fuels will decrease the release of carbon dioxide into the atmosphere and it is the major merit of using bio-fuels. Butanol can be directly used as a fuel in vehicles having 30% higher energy content than that of ethanol. The fermentation is not efficient due to the great cost associated with the separation of butanol from the fermentation broth. In present paper, various separation techniques were reviewed briefly and membrane based methods are more promising than others.</p>2018-06-30T00:00:00+00:00Copyright (c) 2018 Kailas L.

In the experimental work natural coarse aggregate was replaced by recycle aggregate in the proportion of 0, 25, 50, 75 and 100%. The Polypropylene fibres (PP) were used in the recycle aggregate concrete by 1 and 2% volume. After conduction of experiments on the cube and cylinder specimens, the results showed that, the incorporation of PP fibers increases the strengths of RAC. Few Regression Models were deduced to estimate the strengths for RAC and Finite Element Method (FEM) analysis was performed on cube and cylinder specimens to identity the stress variations in the specimens. The average result of Finite Element (FE) analysis for each specimen is checked with the experiments results and it is noticed that the variation is about 2%.</p> <p> </p>2018-06-30T00:00:00+00:00Copyright (c) 2018 N.
