This paper presents the simulation of a hybrid Wind-Diesel power plant. Combining two or more generating technologies such as wind and diesel creates a hybrid power system. For remote locations, far from public power grid, the hybrid system forms a self sufficient power supply. This paper presents the modelling and simulation of an isolated Wind/Diesel system. High-penetration, no-storage wind diesel (HPNSWD) system requires a fast-acting dump load controller to maintain the system frequency stability and quality. Individual system components i.e Diesel Set and Wind Set are simulated and discussed in detail. The impact of penetrative variations wiz variations of wind speed, distance between Wind turbine and Diesel generator and fault analysis is effectively demonstrated by simulation results. © Research India Publications.

Regression testing is a kind of software testing that seeks to find out new software errors, or regressions, in existing functional and non-functional areas of a system after modifications such as enhancements, patches or pattern-changes, have been build to them. Automation tools are required for regression testing. Regression testing is to verify whether a modification in one division of the software affects other division of the software. This testing is done to build that new code modifications should not effects on the existing performance of the software. It ensures that existing code still works with new code modifications are done. Regression testing is to ensure that modification made to system, such as adding new functions or changing existing functions, have not unfavorably affected functions of the software that should not modify. In this paper, enhanced in genetic algorithm has been proposed which increases the efficiency of test prioritization and increase reliability of the software. © Research India Publications.

Text retrieval is a popular technique applied for software engineering tasks. These are at least 20 tasks including reuse, code retrieval, reverse engineering, bug tracking etc. In software engineering, component based software development or component based software engineering is a more effective and reuse based approach. This approach has attained importance from researcher point of view as well as company prospective. Retrieving component from repository is a challenging task. This paper look into how k mean work on set of requirements documents and test cases by clustering documents with similar properties into single course and those with unlike properties into another course and to resolve static clustering in case of k mean by proposing the approach for dynamic requirement clustering with usable test cases. © Research India Publications.

Rapid urbanization and population growth makes efficient management of municipal solid waste (MSW) a challenge to municipal authorities. Considering this, the current study appraised the MSW practices including waste generation, collection, transportation, disposal and treatment in Chandigarh. The strength of MSW management includes the involvement of various public-private stakeholders including the Municipal Corporation of Chandigarh (MCC). The city has door to door waste collection system for its transportation at collection-cum-transfer station (Sehaj Safai Kendra, SSK). From SSK MSW is transported to Refuse Derived Fuel (RDF) plant. RDF plant utilizes the combustible fraction of MSW but discard organic fraction, which is dumped at an open disposal site. If the total MSW from Chandigarh is diverted to RDF plant it could reduce 5451 tCO2 emission per year and has potential to earn carbon credits under Clean Development Mechanism (CDM). Further, based on system analysis approach the study proposes options for the improvement in current waste management practices in Chandigarh, which could also be adopted by other cities in developing world to reduce the adverse impact of MSW on environment and human health. © 2014 Elsevier Ltd.

The consumption of various forms of plastics is a challenging environment protection issue. All forms of consumed plastic become waste and require large areas of land for storage because several tons of waste plastics cannot be fully recycled at once. The low biodegradability of plastic and the presence in large quantities of waste plastic negatively impact the environment. Previously, various studies were performed to identify safe and environmentally friendly methods for disposing of plastics. Recently, various forms of plastics have been incorporated in concrete to prevent the direct contact of plastics with the environment because concrete has a longer service life. However, this method is not a dominant method for disposing of waste plastic. This paper presents an overview of some published research regarding the use of waste plastic in concrete. The effects of waste plastic addition on the fresh, mechanical and thermal properties of concrete are also presented in this paper. © 2015 Elsevier Ltd.
