1 Identifying Knock-On Delays in the Trains by using Base Classifier
D.Kishore Babu, B.V.Ram Kumar, A.S.G.R.Srinivas

Abstract-Train regularity is one of the most significant success factors for a railway traffic system. And it is one that largely affect on passengers. Despite the importance of punctuality (On-time table, on-time performance, schedule adherence [agreement]), there seems to be a lack of broad understanding when it comes to the formation the act of punctuality. Within a railway traffic system, delays concatenate easily, that is, a single delay is likely to cause many other delays, socalled secondary delays. As well as ternary delays, to date, most of the studies related to delays have examined only stations and station-like systems. It is more important to limit the lengths of the transport times, rather than having high punctuality, i.e. adherence to timetable. Generally, for freight transports it is difficult to give an estimation of the cost for unpunctuality. However, especially within a singletracked infrastructure as in India a notable portion of ternary delays takes place outside stations. Thus, the examination of delay concatenation should be done by considering the whole network.

Mahavir A. Devmane, N. K. Rana

Abstract-The rapid growth of the volume of user-generated data on the Online Social Networking (OSN) sites such as Facebook, LinkedIn, Twitter, MySpace and Google+ has raised the privacy and security concern. As there are more than a Billion users of these Online Social Networks across the globe this is a serious matter to be handled with priority. The results of our previous work in field of privacy as well as analysis based on the outcomes of the survey conducted by us, it is found that OSN users are less careful about privacy and security of their own data. So there is a need of time to design a privacy and security framework for the Online Social Networks. The proposed privacy and security framework take into consideration not only the users but also the Online Social Network and Third-Parties related to it. So this framework will be a complete and unique considering all the entities. Further this framework will not be related to a typical Online Social Network but it will be general in nature and applicable to all the existing OSNs as well as will be useful while designing new Online Social Networks.

5 Voltage regulation in multiple distributed energy resources by using adaptive voltage control technique
K. Sindhu, G.Laxminarayana, M. Narendar Reddy

Abstract-An adaptive voltage control method has been proposed to dynamically modify the control parameters of a single Distributed energy (DE) to respond to system changes such that the ideal response can be achieved. Theoretical analysis shows that a corresponding formulation of the dynamic control parameters exists; hence, the adaptive control method is theoretically solid. Then, control methods have been discussed in the case of multiple Distributed energy resources regulating voltages considering the availability of communications among all the Distributed energy resources. When communications are readily available, a method is proposed to directly calculate the needed adaptive change of the Distributed energy resource control parameters in order to achieve the ideal response. When there is no communication available, an approach to adaptively and incrementally adjust the control parameters based on the local voltage changes is proposed. Since the impact from other Distributed energy resources is implicitly considered in this approach, multiple Distributed energy resources can collectively regulate voltages closely following the ideal response curve.

Saurabh Verma, Nitin Malviya

Abstract-Combustion of a modern slow velocity diesel engine produces exhaust gases which encompass gases together with NOx, SOx, CO, CO2. Of these NOx is most crucial due their feasible carcinogenic effect, contribution to photochemical smog formation over towns. This NOx converted to high-quality particles and nitrate aerosols. These particles get thru the lungs and small enough to pass via the tissue and enter the blood. They can then cause inflammations which subsequently purpose heart and lungs failure. The NOx can be reduced each by using pre-remedy like enhancing gasoline valve design, by means of varying the gasoline timing, blending of water with the gasoline and introducing water vapour in the combustion chamber and submit combustion remedy (e.g. SCR, Exhaust gasoline recirculation approach), of those SCR i.e. Selective catalytic reactor is part of the satisfactory tool for folks that are inquisitive about NOx reduction. With the SCR method, the exhaust gasoline is mixed with ammonia NH3 or urea (as NH3 carrier) earlier than passing via a layer of a special catalyst at a temperature among three hundred and 400°C, wherein NOx is reduced to harmless N2 and H2O. The SCR can reduce the NOx emission by ninety to ninety five % however it depends upon the diverse restricting factors like the temp difference of the reactor , the degradation or deactivation of catalyst over the years , SO2 to SO3 conversion which similarly converted to Sulphuric acid, Crystallization of Urea in the injector nozzle.

9 A Review Paper on Numerical Simulation of a Helical Heat Exchanger with Parameters
Pradeep Tripathi, Rohit Kumar Choudhary

Abstract-Flow and heat transfer modelling solution for industry Continuous and rapid technological advances in industrial processing require that design and operation problems be resolved as quickly as possible in order to keep companies competitive, particularly in terms of energy efficiency and low costs. For many years, experiments and empirical analysis have been the preferred solution tools for industrial analysis. Despite the robust and reliable nature of experimental methodology, certain factors limit its applicability scope. For example, flows in process installations are usually very complex; the use of experimental methodology in related analysis may demand significant simplification or a vast number of experiments to achieve an acceptable solution, indicating both cost and time constraints. Thus it has become a necessity to use advanced modelling and simulation tools in industry, and the number of industries benefitting from these products continues to expand. Computational fluid dynamics (CFD) is a computer simulation technique used for fluid flow and heat transfer modelling. Based on increasingly powerful computer resources, CFD can be applied to solve industrial flow and complex phenomenon problems. However, there still exists a lack of data for CFD applications in different industrial areas enabling the development of general guidelines in specific numerical heat and flow studies.

Binayak Sarkar, Maitreyee Ghoshal, Angira Das, Dr.Arup Kumar Mitra

Abstract-Arsenic contamination possesses a major threat to a large section of the people of West Bengal, particularly in the districts of North and South 24 Parganas, Malda, Murshidabad, Howrah, Hooghly, Bardhhaman, Nadia etc. affecting nearly 30 million people (WHO report, December, 2012). With this respect, the common Cattail (Typha latifolia ) has proved to be quite efficient in the uptake of arsenic from arsenic contaminated soil. In this study, an attempt has been made to increase the efficiency of arsenic biosorption by a three tier composite system containing three combinations - Plant in Knop’s Solution, plant with Alterneria spp and the plant with a bacterial suspension. The entire arrangement has reduced the supplied initial Sodium Arsenite concentration from 110 mg/L to 29.180 mg/L, over a period of 45 days as detected by ICP-MS (Inductively Coupled Plasma mass Spectroscopy) with the arrangement containing the plant and the fungal culture proving to be the most efficient (more than 50% uptake).The second phase of the experiment focuses on the biochemical analysis, characterisation and an approximate Genus level identification of the isolated bacteria by different biochemical tests. The bacterial strain isolated was found to be Gram negative straight rods showing positive results in catalase, oxygenase and Citrate-utilization tests and negative in Indole, Methyl Red and Voges-Proskauer tests. Based on the biochemical results, colony morphology and its arsenic tolerant behaviour, the Genus was proposed to be Xanthomonas. spp.Thus, the work has wide future applications as combined action of the plant, fungi and bacteria has shown promising results.
