With the tremendous growth of applications and wide demand of high performance architecture, the demand for virtual or cloud based architecture is also growing. The architecture demand focused on computing, storage and networking is directing the research towards the cloud based data centers. The migration towards the cloud based data centers from the traditional data centers is the recent trends of the modernization of architecture to match the demand of high performance computing. However the optimal settings of hardware availability based on the utilization, up time and cost factors is yet to be determined. Also the generic performance and setup differences between traditional data centers and cloud based data centers are also to be defined. The recent progress of the researches limit to justify the complexities of cloud based data center architecture. Moreover the most suitable performance matrix to evaluate the data center hardware performance is also to be defined. Thus this work demonstrates the framework for optimal component based data center architecture reducing the redundant components and evaluates the performance of the framework on the proposed matrix for data center hardware component evaluation. Moreover this work demonstrates the fundamental strategies of data center hardware resource optimization. The final outcome of this work is optimal framework simulation tool based on CloudSim toolkit. © 2016 IEEE.

The fossil fuels plays highly dominant role in energy scenario. These fuels are nonrenewable, scare and exhaustive in nature. Biodiesel act as alternative to conventional diesel fuel, they are renewable and ecofriendly. The present work is focused on biodiesel production from waste chicken fat and its cost estimation. It includes the process of chicken fat biodiesel preparation and various costs involved for raw materials, energy and labor. Chicken fat biodiesel was produced by transesterification process and production cost wasestimated using some existing data and suitable assumptions. It was estimated that the chicken fat biodiesel production cost come around ₹24.7 per liter. Hence the waste chicken fat proves to be suitable for biodiesel production, safe passage of dispose of waste and economically viable. © Research India Publications.

The paper deals with dynamic stability and natural frequency of composite corrugated bellows expansion joint. In this simplified formulae are developed by a thin walled pipe model. The dynamic model determined by integration method. According to the EJMA formulae the torsional stability calculation is modified using two different equivalent radii. The torsional natural frequencies are calculated using the formula based on equivalent thin walled pipe model. The modified formulae are verified by those from a finite element model and good agreement is shown between the simplified formulae and the finite element model. © (2013) Trans tech publications, Switzerland.

In Compression Ignition engines, formation of NOX is highly temperature dependent phenomenon and takes place when the temperature in the combustion chamber is very high (exceeds 2000 K). The problem of NOX emission is also high when diesel engines are operated with biodiesel due to availability of more Oxygen. Therefore in order to reduce NOX emission in the exhaust, it is necessary to keep peak combustion temperature under control. One simple way of reducing the NOX emission of compression ignition engine is by injection delay of fuel in to combustion chamber. This method is effective but increases the fuel consumption, which necessitates the use of more effective NOX reduction technique like Exhaust Gas Recirculation (EGR). Recirculating part of the exhaust gas along with fresh air admission helps in reducing NOX. An experimental investigation was conducted to study the effect of Exhaust Gas Recirculation on diesel engine Performance and Emission characteristics fueled with Waste Cooking Oil Methyl Ester and its blends with diesel. The EGR setup required for this work was developed on a single cylinder, direct injection, water cooled compression ignition engine. Waste Cooking Oil Methyl Ester produced by Transesterificaton process was used to operate the engine. The different EGR rates ranging from 0% to 20% in steps of 5% for waste cooking oil methyl ester blends with diesel fuel were consider for the study of various Performance and Emission characteristics. For all blends reduced NOX emission was observed with EGR. The better engine characteristics were obtained with EGR rate of 15% for all fuel blends. ©2006-2015 Asian Research Publishing Network (ARPN).

Present days popularity of cloud computing increased concurrently with respect to out sourcing data into multiple users in cloud. However, delicate information should be secured before outsourcing for privacy requirements, which obsoletes information usage like keyword-based papers recovery. Traditionally more number of techniques/methods were introduce for information retrieval in out sourced cloud. In this paper we analyse four methods for information retrieval in outsourced data from cloud. We formalize the problem of fuzzy search from encrypted cloud data. Our analysis provides a realistic and effective data retrieval from different data cloud data storage. Boolean data retrieval is the main proceeding concept in data retrieval from cloud with respect to time and concept wised data retrieval in cloud data storage. Our analysis provides compatative analysis of different techniques to support above conditions equally with preferred results in cloud data storage.

Biodiesels produced from vegetable oils are an attractive alternative fuel which are renewable and offer significant reduction of carbon monoxide and hydrocarbon emission due to higher oxygen content. Biodiesels can be easily mixed with petroleum diesel to form blends, and is free of sulphur. Emission control has become one of the most important challenges in diesel engine. The main drawback of use of biodiesels in diesel engines is its higher NOX emissions. The aim of the present work is to reduce NOx emissions of a diesel engine fueled with cotton seed biodiesel. One simple way of reducing the NOX emission of diesel engine is by injection delay of fuel in to combustion chamber. This method is effective but increases the fuel consumption, which necessitates the use of more effective NOX reduction technique like exhaust gas recirculation (EGR). Recirculating part of the exhaust gas along with fresh air admission helps in reducing NOX. A single cylinder four stroke direct injection water cooled diesel engine operated with cotton seed biodiesel (CSBD) and petroleum diesel (PD) blends such as 0% (PD), 10% (CSBD10), 20% (CSBD20) and 30% (CSBD30) are used for the present emission and performance study. Different EGR rates such as 0%, 5%, 10%, 15% and 20% are considered for this study. The speed of the engine is kept as constant at 1500 rpm. The performance of the engine in terms of brake specific fuel consumption& brake thermal efficiency and emission characteristics such as oxides of nitrogen, hydrocarbon & carbon monoxide are studied. For all blends reduced NOX emission was observed with EGR. The better engine characteristics were obtained with EGR rate of 15% for all fuel blends. The observations reveal that cotton seed biodiesel with EGR can be used to reduce NOx. © 2016 IJENS.
