Abstract

This paper presents an optimization of corridor observation method (COM) which is an applicable optimization algorithm based on the evolutionary algorithm to solve an environmental and economic Dispatch (EED) problem. This problem is seen like a bi-objective optimization problem where fuel cost and gas emission are objectives. In this method, the optimal Pareto front is found using the concept of corridor observation and the best compromised solution is obtained by fuzzy logic. The optimization of this method consists to find best parameters (number of corridor, number of initial population and number of generation) which improve solution and reduce a computational time. The simulated results using power system with different numbers of generation units showed that the new parameters ameliorate the solution keep her stability and reduce considerably the CPU time (time is minimum divide by 4) comparatively at parameterization with originals parameters.

Keywords:bi-objective, corridors observation, fuel cost, gas emission, new parameters, optimal Pareto front, optimization, original settings.

Abstract

One method for searching the internet faces in images is proposed by using digital processing topological with descriptors. Location in real time with the development of a database that stores addresses of internet downloaded images, in which the search is done by text, but by finding facial image, is achieved. Face recognition in images of Internet has proved to be a difficult task, because the images vary considerably depending on viewpoint, illumination, expression, pose, accessories, etc. The descriptors for general information: containing low-level descriptors. Developments on face recognition systems have improved significantly since the first system; image analysis is a topic on which much emphasis is being given in order to identify parameters, visual features in the image that provide environment data that it is represented in the image, but without the intervention of a person. In this project raises its realization using the method of viola and jones as face descriptor. We can distinguish even different parts of the face such as eyes, eyebrows, nose and mouth.One method for searching faces in image taken from internet intends to use digital processing using topological descriptors. It is located the face in real time.

Keywords:Face Recognition, viola and jones, identifying people, Internet, descriptor for points.

Abstract

This Paper is based on an experiment carried out on different roofing sheets namely aluminum, galvanized steel, plastic and asbestos of various grades. The aluminum samples were obtained from two different companies in Nigeria namely First Aluminum and Tower Aluminum; the Asbestos was obtained from Emenite while the Steel and Plastic samples were bought from the market. The samples were cut into a particular size (8cm by 5cm) and immersed in various media namely acidic (H2SO4), alkaline (NaOH), Sea water and Rain water in 2litres plastic beakers. The Rain water was used as the control medium for the experiment. The experiment was carried out for 70days and each grade was cut into 14 pieces of the same dimension. The samples were washed, weighed and tagged before immersion in the media. Each sample was removed every 5 days, washed thoroughly, dried and re-weighed. Some of the samples corroded while some resisted corrosion. The differences in the weights of the samples, and hence their respective rates of corrosion were obtained depending on the reacting media. The values that were obtained, the weight loss and weight gain were used to determine the corrosion rates per unit area per unit time. Graphs of specific weight loss/gain against time were plotted for each medium and each sample. Based on our graphs and observations, we can say that the coated samples are more resistant to corrosion, and therefore more durable.

Keywords:Roofing Sheets, Aluminum, Galvanized Steel, Corrosion, Asbestos.

Abstract

An efficient and secured routing protocol design is the vital concern for mobile ad hoc networks in view of major problems raising on security issues and loss of the network resources is due to changes within the connections of the network like Node failures, link breakages in the network. Our proposed scheme enhances the secured and reliable transmission of data, which also improves the network constancy, efficient packet delivery ratio and network life time by integrating through the AODV Routing protocol. It unites the authentication, stable routes and signal strength of the nodes to attain the secure and reliable transmission of data through nodes.

Abstract

Mobile Adhoc Networks is non-infrastructure, self configuring and decentralized set of mobile nodes. So the routing protocols for mobile adhoc networks have to face the challenge of frequently changing topology low transmission power and asymmetric links. This work deals with one of the most popular routing protocols in MANETs i.e. Zone Routing Protocol (ZRP). In this work, we address the issue of self configuring framework for the ZRP to provide the best performance for a particular network at any time. As the name indicates the MANET's are specially defined for the mobility of the nodes in the networks. The nodes may move at a different speed, which may enter or move out of the network, which leads the delay, jitter, and link failure conditions during the transmission of packets. In the large networks, the more number of nodes will accept these parameters at a same time or random time. Such that scalability problem in the network may arise. Without a fixed infrastructure, mobile adhoc networks have to rely on the portable, limited power sources. Therefore the energy-efficiency becomes one of the most important problems in MANETs. Other challenging aspects on MANETs are node cooperation, interoperation with the internet, aggregation, multicast as well as changing the network topologies. Technologies such as smart antennas, software's will also bring new problems along with impetus to adhoc to MANETs. We discuss the factors influencing on improvement in performance of Zone routing protocol, performed in number of related works. This work is based on literature research. The proposed protocol is based on the principle of self reconfiguring, multicast, query detection based, low bit error rate mode of operation. This work aims to optimize the Quality of Service in transmission for the zone routing protocol. Through test-bed simulation, we demonstrate that our proposed work will allow the ZRP to operate a better reconfiguration framework during link failure conditions.

Abstract

The paper discusses the voltage control of a critical load bus using dynamic voltage restorer (DVR) in a distribution system. The critical load requires a balanced sinusoidal waveform across its terminals preferably at system nominal frequency of 50Hz .It is assumed that the frequency of the supply voltage can be varied and it is different from the system nominal frequency. The DVR is operated such that it holds the voltage across critical load bus terminals constant at system nominal frequency irrespective of the frequency of the source voltage. In case of a frequency mismatch, the total real power requirement of the critical load bus has to be supplied by the DVR. Proposed method used to compensate for frequency variation, the DC link of the DVR is supplied through an uncontrolled rectifier that provides a path for the real power required by the critical load to flow .A simple frequency estimation technique is discussed which are Discrete Fourier transform (DFT), ANN controller. The present work study the compensation principle and different control strategies of DVR used here are based on DFT, and ANN Controller .Through detailed analysis and simulation studies using MATLAB. It is shown that the voltage is completely controlled across the critical load.
