Abstract: Sensors in most of the Wireless Sensor Networks (WSN) rely on batteries as the source of energy. The power backup is one of the major constraints. It is impractical to recharge or reinstate sensor nodes as they are deployed or located in the areas which are not easily accessible by humans. So Efficient-Energy Coverage (EEC) has become challenge issue for WSN. So the lifetime of a network can be prolonged and energy consumption be minimized by scheduling the actions of these nodes. The present paper deals with an Ant Colony Based Scheduling Algorithm (ACB-SA) to resolve the EEC issue. We apply ACB-SA to a heterogeneous sensor set by the execution of PSD model. The simulation results are carried out by using MATLAB.
Key Words: Probabilistic Sensor Detection (PSD), Efficient Energy Coverage (EEC), Ant Colony Optimization (ACO), Ant Colony Based Scheduling Algorithm (ACB-SA), Base Station (BS)..

Abstract: In order to get the information of any vehicle which is travelling on the way we required to rely on Global Positioning System. The GPS provides the Global Positioning Information of vehicle, which relies on external source called satellites. But the satellite signal may get cut or have small signal strength in cluttered areas or is less reliable at low altitude areas, so I think of to use the Unmanned Aerial Vehicle. The main objective is to use the Raspberry pi to capture the stream of video to monitor and to detect the color or objectsy............

Abstract:The main aim of this work is to propose a novel Computer-aided detection (CAD) system based on a Contextual clustering combined with region growing for assisting radiologists in early identification of lung cancer from computed tomography(CT) scans. Instead of using conventional thresholding approach, this proposed work uses Contextual Clustering which yields a more accurate segmentation of the lungs from the chest volume. Following segmentation GLCM and LBP features are extracted which are then classified using three different classifiers namely Random forest, SVM and k-NN.

Keywords: Computer aided detection(CAD);computed tomography(CT)imaging; lungcancer; Support vector machine(SVM); Random forest(RS); K-NN.

Abstract:Electroencephalographic (EEG) signal is electrical record generated by the brain. It is a vital signal as far as the monitoring, diagnosis and treatment of some health conditions that relate to the human brain are concerned. EEG artifact contaminants have the capability to distort he usefulness of this important bio-electrical signal. Such noises include power line interference, baseline wander, eye blink and eye movement (electro oculogram, EOG) as well as muscle artifacts also called electromyogram (EMG and electrocardiogram (ECG). These are identified as artifacts..............

Abstract:Contingency analysis is an abnormal condition in an electric power network. It puts whole system or a part of the system under stress. It occurs due to sudden opening of a transmission line, generator tripping, sudden change in generation or sudden change in load value. Electric power networks are designed to withstand one contingency thus (N-1) criterion. However, some events trigger others and cascading failures may occur. Therefore, not all contingencies are equal, and the number of components in a given system makes it prohibitive to evaluate all or a single contingency............

Abstract:As Electric Vehicle is becoming a promising alternative for sustainable and cleaner energy emission in transportation, modeling and simulation of Electric Vehicle has attracts increasing attentions to the researchers. This paper presents a simulation model of Full Electric Vehicle in Matlab-Simulink platform to examine power flow during motoring and regeneration. Every components of the key system drive train consist of motor, battery, motor controller and battery controller were acknowledged and modeled from their mathematical equations. All simulation results were plotted and discussed. The torque and speed conditions during motoring and regeneration were used to determine the energy flow, performance and efficiency of the drive.

Abstract: Increased demand for electrical energy and free market economies for electricity exchange, have pushed power suppliers to pay a great attention to quality and cost of the latter, especially in transmission networks. To reduce power losses due to the high level of the reactive currents transit and improve the voltage profile in transmission systems, shunt capacitor banks are widely used. The problem to be solved is to find the capacitors optimal number, sizes and locations so that they maximize the cost reduction. This paper is constructed as a function of active and reactive power loss reduction. To solve this constrained non-linear problem, a heuristic technique, based on the sensitivity factors of the system power losses, has been proposed. The optimal location TCSC is studied on the basis of Particle Swarm Optimization (PSO) to minimize network losses. Validation of the proposed implementation is done on the IEEE-14 and IEEE-30 bus systems..

Abstract: The role of computers and the Internet in modern society is well recognized. Wi-Fi internet connection have become increasingly popular, it can become the spring board for rapid economic growth in the rural areas but the rapid growth of Wi-Fi access has also contributed to unethical practices by individuals who are bent on using the technology to exploit others. Such exploitation of Wi-Fi network for the purpose of accessing unauthorized or secure information, spying, disabling of networks and stealing both data and money is termed as Wi-Fi threats. Such attacks have been increasing in number and complexity since last few years. Hence there is a need to have comprehensive understanding of Wi-Fi threats. For keeping in view of Wi-Fi adoption and Security I am conducting a survey in old Shahabad (i.e. Bhojpur, Buxar, Rohtas and Kaimur)............. .

Abstract: For satisfactory, secured and economic operation of a power system, the frequency should remain nearly constant. The only way to maintain system frequency within an acceptable range is to make balance between generation and load in real time. Power system frequency in Bangladesh varies routinely on a normal days between 48.9-51.2 Hz and can go as low as 48.7 Hz and as high as 51.5 Hz under contingency. This is a major impediment to system reliability and also causes a severe economic loss including our-of-merit dispatch............ .
