CuAlSe2 films were pulse electrodeposited on tin oxide coated glass substrates at different duty cycles for the first time. X-ray diffraction studies indicated single phase chalcopyrite CuAlSe2. Strain, crystallite size and dislocation density were evaluated from the X-ray diffraction data. The Cu/Al ratio approaches unity at higher duty cycles. Electrical transport properties of the films indicated that the resistivity of the films decreased with increase of duty cycle. Photoelectrochemical cells were fabricated with the films deposited at different duty cycles. Films deposited at 50 % duty cycle indicated high photo output. Capacitance voltage measurements were made and the nature of the plot indicated p-type behaviour. © 2015, Springer Science+Business Media New York.

The problem of service disruption in dynamic reconfiguration has not been studied well for the quality assurance. The dynamic reconfiguration must reduce the level of system transformation without disturb the service that much. We propose a new dynamic reconfiguration strategies for the components of the software system which will be prioritized based on the completeness measure. We use the state of cob for the selection of service for the user request and which helps the dynamic reconfiguration of components without disturbing the ongoing services. The completeness measure is computed based on the frequency of successful completion and failure completion of the service. We broadly explore the service reconfiguration strategies and we describe the model for reconfigurable components. The proposed component model is evaluated with the benchmark methods of reconfigurations. The notable inference of our examination is that the classified QoS physiognomies can be fully achieved under some acceptable restraints. © Medwell Journals, 2016.

AgInS2 films were pulse electrodeposited on tin oxide coated glass substrates at different duty cycles for the first time. The films were single phase with orthorhombic structure. Optical absorption measurements indicated a band gap in the range of 1.90-2.02 eV with decrease of duty cycle. Transmission spectra exhibited interference fringes. Using the envelope method, refractive index was calculated. Optical conductivity was evaluated from the absorption coefficient and refractive index data. Optical data was analyzed by the single-effective oscillator model. © 2014 Springer Science+Business Media New York.

Distribution system is a critical link between customer and utility. The control of power loss is the main factor which decides the performance of the distribution system. There are two methods such as (i) distribution system reconfiguration and (ii) inclusion of capacitor banks, used for controlling the real power loss. Considering the improvement in voltage profile with the power loss reduction, later method produces better performance than former method. This paper presents an advanced evolutionary algorithm for capacitor inclusion for loss reduction. The conventional sensitivity analysis is used to find the optimal location for the capacitors. In order to achieve a better approximation for the current candidate solution, Opposition based Differential Evolution (ODE) is introduced. The effectiveness of the proposed technique is validated through 10, 33, 34 and85-bus radial distribution systems.

Wireless multi-hop adhoc network, a group of mobile devices or nodes form an infrastructure-less wireless network. Packets are relayed over multiple hops from source to destination via wireless links. The attractive characteristics of wireless ad hoc networks are ease of deployment, no wired installation, maintenance cost, and flexibility of mobility. In a number of environments, there is a role for the wireless multi-hop ad hoc networks as an alternative to a wired LAN. Some example include building with large open areas, such as manufacturing plants, stock exchange trading floors, and warehouses; historical buildings with insufficient twisted pair and where drilling holes for new wiring is prohibited; and small offices where installation and maintenance of wired LANs is not economical. In all of these cases, a wireless multi-hop ad hoc network provides an effective and more attractive alternative. In this work we developed an algorithm named Explicit Congestion Control Protocol with Buffer Management (ECCPBM) for Multi-Hop Wireless Networks which controls the congestion in the wireless network and fairly allocates the network resources among the communication flows and also minimizes the delay of packet sending between the source and destination.

A smart grid is an electrical grid that uses smart meters and other devices to gather and act on information, such as information about the behaviors of suppliers and consumers, in an automated manner to improve the efficiency, reliability, economical, and sustainability of the production and distribution of electricity. Smart grid is a new emerging technology which is able to intelligently control the power consumption via network. Therefore, the efficiency of the information exchanges between the power suppliers (or control centers) and power customers are an important issue for smart grid. Moreover, the performance of the smart grid usually depends on the customer satisfaction degree which belongs to the field of quality of experience. Now-a-days, power consumption by the end users has increased a lot, prices of electricity is increasing day by day but the power production is reducing and always there is a scarcity in the required power. To overcome all these problems, smart grid is very helpful. In this thesis, we propose to study and analyze various QoE issues of smart grids for efficient use of power. We aim at proposing QoE aware power scheduling for effective utilization of power.

Power delivery performance of the distribution systems has to be enhanced with help of recent technologies. System efficiency can be improved by controlling power loss. The popular techniques adapted to control the power loss are Distribution system reconfiguration and optimal capacitor placement. This paper proposes a method to handle reconfiguration and capacitor placement simultaneously for the effective optimization. It utilizes Opposition based Differential Evolution (ODE) algorithm for efficient searching for the optimal solution. In order to consider the constraints along with the objective, heuristic Fuzzy has been integrated with ODE and the proposed technique is termed as FODE. The effectiveness of the proposed approach is demonstrated by employing the feeder switching operation scheme to 83-Bus Taiwan Power Company Distribution System The proposed algorithm reduces the transmission loss and improve the saving of cost while satisfying power flow constraints. © Research India Publications.

Bending is one of the processes often used during manufacturing of sheet metal components in manufacturing industry. Springback becomes an important issue in bending operations while producing precision parts. Springback occurs when a material’s tendency to return its original state, once its state of motion has been disturbed. The angle between the target bend and the original after elastic release is called springback angle. Many parameters affect springback in the bending process; Therefore, the springback effect prediction in wipe bending process of sheet metal is important to improve quality of metals. Many methods were introduced to improve the performance of springback effect prediction in wipe bending process of sheet metal. One of those methods is the artificial neural network with genetic algorithm for the prediction of springback angle in sheet metal. To improve the prediction efficiency of springback angle, this paper proposed a genetic algorithm with Cauchy mutation operator to provide sufficient training to artificial neural network. The proposed GA-ANN with Cauchy mutation operator approach performed better than the conventional ANN approach and the proposed method was be implemented in the working platform of MATLAB. © Research India Publications.

Sheet metal is one of the most important semi-finished products used in automobiles, domestic appliances, aircraft and other familiar products. Therefore sheet metal forming technology is an important engineering discipline in the area of mechanical engineering. In sheet metal forming, wipe bending process plays a major role in which the sheet metal tries to return to its original shape after release of the load by a punch, due to the elastic stresses. This phenomenon is called as springback and the angle between the target bend and the original after elastic release is called sprinback angle. Springback angle prediction is essential while engaging with such wipe bending processes. State of the art methods use Artificial Neural Network with conventional configuration for the prediction of springback angle. To improve the prediction efficacy, this paper exploits Genetic Algorithm to provide appropriate training to Artificial Neural Network. The experimental investigations show that the proposed ANN approach predicts more precisely compared to the conventional ANN approach. © 2005-2013 JATIT & LLS. All rights reserved.
