<#LINE#>Reduce the Harmonics Distortion of Sensitive Load against the Induction Motor Drive Non-Linear Load<#LINE#>S@Jain,esh@,ShivendraSingh@Thakur,S.P.@Phulambrikar<#LINE#>1-8<#LINE#>1.ISCA-RJEngS-2012-088.pdf<#LINE#><#LINE#>22/10/2012<#LINE#>2/11/2012<#LINE#>This paper discusses for reduce the harmonics distortion of sensitive load against the induction motor drive load. Electronics devices are very sensitive load against harmonics. DVR proposed not only to improve PQ but also to reduce HD due to the presence of non-linear load. The DVR consists of injection transformer, filter, and ESS, VSI and control system. The basic function of injection transformer is to connect the DVR to the distribution network via the HV- wdg. In DVR LC filter can be achieved by eliminating the unwanted harmonics. The ESS can be suitable capacity. The ESS such as battery is responsible to supply energy in DC form. A VSI is a power electronics system consist of switching device which can generate a sinusoidal voltage. The disturbance is carried out with the help of d-q-0method. Simulation results carried out by MATLAB verify the performance of the given method.<#LINE#>@ @ Roger C. Dugan, Mark F. Mcgranaghan, Surya Santos and H.

The aim of this study was to investigate the potential of Agbani clay as a low-cost adsorbent for Lead(II) ions from industrial wastewaters. The adsorption experiment was performed using batch technique to investigate the effect of pH, initial metal ion concentration, temperature and time. All these parameters proved to be useful in the description of the adsorption process. An optimum pH of adsorption was achieved at 6.0. Equilibrium isotherm models showed the Freundlich isotherm with the best fit as indicated by the regression coefficient R value of 0.9891, this was followed by the Temkin isotherm, (0.9121) and the least the Langmuir isotherm (0.8687). Kinetic studies revealed the Pseudo-second order with the best fit of 0.9982, although a good fit was also obtained (0.9924) by the Pseudo-first order model. Thermodynamic analysis showed a spontaneous adsorption process as negative values of  were obtained at all temperatures. The positive enthalpy change , (14.37KJ/mol) indicated an endothermic process and an increase in adsorption with increase in temperature was observed. A highly disordered process was indicated by the positive entropy change  (62.75J/molK). The results showed the applicability of Agbani clay as a low cost adsorbent for lead(II) ions from aqueous solution. <#LINE#> @ @ Shan H.Y., Wase D. and Forster C., Removal of Lead Ions from Aqueous Solution Using Sphagnum Moss Peat Adsorbent, Water.

<#LINE#>A Study on the Effect of Size of Aggregate on the Strength and Sorptivity Characteristics of Cinder Based Light Weight Concrete<#LINE#>P.@RathishKumar,M.V.@KrishnaRao<#LINE#>27-35<#LINE#>5.ISCA-RJEngS-2012-101.pdf<#LINE#>Department of Civil Engineering, National Institute of Technology, Warangal, Andhra Pradesh, INDIA Department of Civil Engineering, Chaitanya Bharathi Institute of Technology, Hyderabad, AP, INDIA <#LINE#>2/11/2012<#LINE#>10/11/2012<#LINE#>It is known that the largest maximum size of aggregate possible to handle could be used in concrete under a given set of conditions. There are benefits of choosing a correct maximum size of aggregate (MSA), viz. reduction in the cement content and drying shrinkage. Variation in the size of aggregate alters the micro cracking of concrete which there by modifies the strength and durability as well. Also, the strength and durability of concrete is dependent on sorptivity, an index of concrete permeability. The pore structure in LWA, which is otherwise porous in nature, can be modified with fly ash inclusion, which not only modifies the density but also enhances the durability of concrete.  In the present study, the strength and sorptivity characteristics of concrete made with cinder-based lightweight aggregates are investigated. Prior to this the size of cinder based light weight aggregate was optimized. The present investigation aims at developing two grades, 20Mpa and 30Mpa, of light weight concrete using cinder based aggregate of different sizes. The results indicated that Light Weight Concrete can be developed with all sizes of graded aggregate satisfying the fresh and hardened state characteristics. The mechanical properties viz., compressive strength and split tensile strengths were studied at the end of 3, 7 and 28 days for medium grade concretes with different sizes of aggregate. It was noted that with 12.5mm size aggregate and 30% flyash replacement, the mechanical properties were superior in 20Mpa Light weight Concrete, while 10 mm size aggregate with a 30% fly ash replacement improved the properties of 30Mpa concrete. There was also an improved performance in terms of sorptivity of fly ash based Light weight Aggregate Concrete.  <#LINE#> @ @ Alengaram U.J., Mahmud H., Jumaat M.Z, and Shirazi S.M., Effect of aggregate size and proportion on strength properties of palm kernel shell concrete, International Journal of the Physical Sciences, 5(12), 1848-1856 (2010) @No $ @ @ Abdullahi M., Al-Mattarneh H.M.A. and Mohammed B.S.,Equations for Mix Design of Structural Lightweight Concrete, European Journal of Scientific Research, 31(1), 132-141 (2009) @No $ @ @ Tumidajsk P.J.,Effect of slag, silica fume, and finishing on the sorptivities of field concrete, Canadian Journal of Civil Engineering, 33(8), 1022–1026 (2006) @No $ @ @ Oliveira L.A.P., Castro Gomes J.P. and Pereira C.N.G.,Study of sorptivity of self-compacting concrete with mineral additives, Journal of Civil Engineering and Management, 12(3), 215-220 (2006) @No $ @ @ Tumidajski P.J. and Gong B.,Effect of coarse aggregate size on strength and workability of concrete, Canadian Journal of Civil Engineering, 76-78 (2006) @No $ @ @ Chen B. and Liu J., Effect of aggregate on the fracture behavior of high strength concrete, Construction and Building Materials, 18(8), 585-590 (2004) @No $ @ @ Tasdemir C.,Combined effects of mineral admixtures and curing conditions on the sorptivity coefficient of concrete, Cement and Concrete Research, 33(10), 1637-1642 (2003) @No $ @ @ ACI 213R-03,Guide for Structural Lightweight-Aggregate Concrete, American Concrete Institute (2003) @No $ @ @ Rathish Kumar P. etal, A study on the Sorptivity characteristics of High Performance Mortars, Journal of Institution of Engineers, 83, 1-7 (2002) @No $ @ @ Rathish Kumar P. etal, A cost effective mix design methodology using Flyash as a partial replacement for cement at the national seminar on Role of Engineering Institutions, Construction Industry and Building Research Institutes in Low cost Housing, M.I.T.S Gwalior January (1996) @No $ @ @ IS: 13311-1992 (Part-1), Indian Standard Method of non-destructive testing of concrete, Bureau of Indian Standards, New Delhi (1992) @No $ @ @ IS: 13311-1992 (Part-2), Indian Standard Method of non-destructive testing of concrete, Bureau of Indian Standards, New Delhi (1992) @No $ @ @ Victor E., Saouma J.J., Brühwiler B.E. and Boggs H.L.,Effect of Aggregate and Specimen Size on Fracture Properties of Dam Concrete, Journal of Materials in Civil Engineering, 3(3), 204-218 (1991) @No $ @ @ Ibragimov A.M., Effect of the maximum size of coarse aggregate on the main parameters of concrete, Power Technology and Engineering, 23(3), 141-144 (1989) @No $ @ @ IS 516-1959, Method of test for strength of concrete, Bureau of Indian Standards, New Delhi, India,The date of publication is 1959 and reaffirmed in 1999 (1999) @No

<#LINE#>Routing Protocols in Mobile Ad Hoc Networks<#LINE#>Nupur@Verma<#LINE#>36-39<#LINE#>6.ISCA-RJEngS-2012-060.pdf<#LINE#> Baba Banarasi Das University, Lucknow, UP, INDIA <#LINE#>4/9/2012<#LINE#>15/9/2012<#LINE#>  With recent performance advancements in computer and wireless communications technologies, advanced mobile wireless computing is  expected to see increasingly widespread use and application, much of which will involve the use of the Internet Protocol (IP) suite. The vision of mobile ad hoc networking is to support robust and efficient operation in mobile wireless networks by incorporating routing functionality into mobile nodes.  Such networks are envisioned to    have dynamic, sometimes rapidly-changing, random, multihop topologies which are likely composed of relatively bandwidth-constrained    wireless links. The design of network protocols for MANETs is a complex issue. These networks need efficient distributed algorithms to determine network organization (connectivity), link scheduling, and routing. An efficient approach is to consider routing algorithms in which network connectivity is determined in the process of establishing routes. Message routing in a decentralized environment where network topology fluctuates is not a well-defined problem. While the shortest path (based on a given cost function) from a source to a destination in a static network is usually the optimal route, this idea is not easily extended to MANETs. Factors such as power expended, variable wireless link quality, propagation path loss, fading, multiuser interference, and topological changes, become relevant issues Some applications of MANET technology could include industrial and    commercial applications involving cooperative mobile data exchange.    In addition,  mesh-based mobile networks can be operated as robust,    inexpensive alternatives or enhancements to cell-based mobile network  infrastructures. A MANET protocol should function effectively over a wide range of networking contexts--from small, collaborative, ad hoc groups to  larger mobile, multihop network.<#LINE#> @ @ Papadimitratos P. and Haas Z.J., Secure Message Transmission in Mobile Ad Hoc Networks, submitted for publication 2.Papadimitratos P., Secure Routing: Methods for Protecting Routing Infrastructures–A Survey, work in progress.

Our aim of modeling of ACTFEL device is to accurately simulate the electrical properties of two-terminal ACTFEL test structures when subjected to realistic applied voltage waveforms. Additionally, modeling method that is believed to hold the most promise for accurate ACTFEL device modeling is presented. In this paper, a series of simple-to-complex models for device operation are offered that are useful for analysis in applications.<#LINE#>@ @ Hitt J.C., Bender J.P. and Wager J.F., Thin-Film Electroluminescent device Physics Modeling, Critical Rev. in Solid State and Material Science, 25(1), 29-85 (2000) @No $ @ @ Bhattacharyya K., Goodnich S.M. and Wager J.F., Monte Carlo simulation of electron transport in alternating-current Thin-Film Electroluminescent devices, J.

It is obvious that the ICT capabilities of a nation to some extent determine its performance in the global economy, politics, education, health and socio-cultural playing field of the 21st Century. These technologies have been incorporated in the daily activities of the western World including peace building efforts. These same technologies are however still struggling to find expression in the developing countries. This paper examines challenges posed by digital divide in mobilizing ICT for peace building. As digital divide is a challenge in many places in the world, increasing information flow and other benefits of ICT first means increasing connectivity and breaking the barriers of digital divide.  <#LINE#> @ @ Ansari A. and Mela C.F., E-Customisation, Journal of Marketing Research, 40 (2003) @No $ @ @ Benigers J.R., Personalisation of Mass Media and Growth of Pseudo Community, Communication Res. 14  (1987) @No $ @ @ Ronald C. and Crawford T.,  Campaigning Against Conflict, ACP ICT Update,  Bulletin, 43, June, (2008) @No $ @ @ Gumisai M., New information technologies Change the lives of those in reach, New York, United Nations (2005) @No $ @ @ Specter J., Bridging the Global Divide: Framework for Access and the world wireless web, North Carolina Journal of International Law and Commercial regulation, 26, 57(2000) @No $ @ @ Noris P., Digital Divide: Civic Engagement, Information, Poverty and the Internet Worldwide, Cambridge, Cambridge University Press (2001) @No $ @ @ Mutula S., Digital Divide in Africa: Its Causes and Amelioration Strategies in Information and knowledge management in the Digital Age: Concepts, Technologies and African Perspective, Ibadan, Third World Information Services Ltd, (2008) @No $ @ @ Servon L., Bridging the Digital Divide: Technology, Community, and Public Policy, Malden, MA: Blackwell, (2002) @No $ @ @ Mehra Bharat; Merkel, Cecelia and Bishop, Ann P., The internet for empowerment of minority and marginalized users, New Media and Society, 6, (2004) @No $ @ @ Curle A., Tools for Conflict Transformation cited in Peace building Bulletin, 1,  (1971) @No $ @ @ Ted P., Peace building, Issue; 43 (2006) @No $ @ @ Pearson J., Nelson P., Titsworth S. and Harter L., Human Communication, Boston, McGraw-Hill Ltd, (2003) @No $ @ @ United States Institute of Peace., ICT for Peace Report, New York, USIP, (2007) @No

This paper is for evaluation of AODV (Ad-hoc on demand distance vector) and DSDV (Destination sequence distance vector) routing protocols’ performance on the basis of different criteria for performance. Here, an attempt has been made to evaluate the performance of two well known routing protocols AODV, DSDV by using three performance metrics such as packet delivery ratio, throughput and Routing overheads. The Performance evaluation has been done by using simulation tool NS2 (Network Simulator) which is the main simulator. <#LINE#> @ @ Siva Ram Murthy C. and Manoj B.S., Ad Hoc Wireless Networks, Architectures and Protocols, Second Edition,Low price Edition, Pearson Education (2007) @No $ @ @ Mamatha G.S. and Sharma S.C., Analyzing the Manet Variations, Challenges, Capacity and Protocol Issues, International Journal of Computer Science & Engineering Survey (IJCSES), 1(1), (2010) @No $ @ @ David B.
