The STHTS problem involves the optimization of nonlinear constrained objective function by taking into consideration of multireservoir cascaded nature hydro plants, water transportation delay between cascaded reservoirs and scheduled time linkages, variable system active load balance, water discharge and reservoir storage limits, initial and final reservoir storage limits, reservoir flow balance and operating limits of hydro and thermal plants. A stochastic search algorithm known as gravitational search algorithm (GSA) inspired from the law of gravity and mass interactions is used to solve this complex constrained STHTS problem. In order to improve the convergence rate of GSA, the opposite numbers are utilized in the evolution process of GSA. Finally, the proposed oppositional gravitational search algorithm (OGSA) approach is evaluated on two test systems, one consisting of four hydro plants and an equivalent thermal plant and the other one with nine cascaded hydro and three thermal plants. The results obtained with the proposed approach give better solution in terms of less production cost, execution time and better convergence characteristics while comparing with the results of other methods reported in the literature.","PeriodicalId":173381,"journal":{"name":"Asian Journal of Current Engineering and Maths","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-06-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131769801","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}

In this article, we performed a numerical study on thermal performances of a parabolic trough solar collector using the nanofluid Al 2 O 3 -Syltherm800 as a working fluid. The mathematical model used in this work is based on energy balances of the collector and has been validated with experimental data of SANDIA laboratories in the USA. A description of thermal properties of Al 2 O 3 -Syltherm800 is presented in this paper.

In this study, an attempt has been made to investigate the displacement scenario of RC residential building seismically located in Zone-V due to the influence of some basic parameters (column dimension, beam dimension, grade of concrete, floor height and seismic weight) in order to obtain a relation which could be used to estimate the expected lateral displacement owing to those selected parameters. In this study, a total of 297 RC buildings designed as per the Indian codal provisions [IS-1893-2002] were analyzed by linear static method using SAP2000 by varying selected and feasible input parameters chosen. The resulting displacements for the change of each parameter were obtained and finally a generalized equation relating the expected displacement as a function of those selected parameters was established using the regression method. The results of the comparison between the displacements obtained from analysis with that of the equation so formed shows that the proposed relation can be used directly to determine the expected displacement with high reliability.","PeriodicalId":173381,"journal":{"name":"Asian Journal of Current Engineering and Maths","volume":"439 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2015-04-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122886906","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}

In this paper, three non-linear differential equations in aerobic degradation processes have been solved using new approach homotopy perturbation method. The proposed analytical expression of concentration of substrate,  production of biomass and oxygen for all experimental values of parameters were validated by comparing the theoretical curves obtained with the corresponding experimental data. The biomass solids is converted into liquid or gaseous of biofuels by heat energy and chemical catalysts.
