Abstract: Electrical power system consist various component. From this component Transmission lines are designed to transfer electrical energy from source locations to distribution networks. Therefore these are vital component of electrical power system. Most of time transmission lines are exposed to various faults in overhead transmission line system. Hence various protective scheme and devices such as protective relay and fault recorder systems, based on fundamental power frequency signals, are installed to separate the faulty line and provide the fault position. However, the error is high especially in transmission lines, so to provide a good quality of electricity as well as to prevent accidents, a study of protective scheme is very important. This paper provides a brief review of various faults and wavelet based fault detection methods used for their detection.

Abstract: The healthcare sector in the world is facing a number of challenges like increasing population, lack of exercise, change in lifestyle and many more. It affects the health of people of any age group. The people get affected with various health problems such as blood pressure and cardiac problems etc. To avoid these health issues, medical monitoring system can play a vital role by regular monitoring of blood pressure, heart rate and haemoglobin at various interval of time. One can send these data to hospitals/doctors for further analysis. Doctor can send appropriate prescription, necessary actions to be taken with the help of IoT platform. This system can help a normal human being/patient to collect data at their residential premises itself without wasting any time in travelling to the hospitals or clinics. This system can be useful for physically disable, senior citizens. This system is user friendly, portable and saves time of particular patient. The Wi-Fi module is used to communicate with the doctor available at remote hospital, where he views patient’s health and prescribe any treatment if necessary.

Abstract: The Flap Turbine (FT) is a novel sort of Vertical Hub Turbine (VAWT) where the cutting edges are made of versatile folds. These versatile folds, when joined together, go about as a sail or cutting edge for the VAWT. This kind of turbine is otherwise called a check valve turbine as a result of the check valve like the conduct of the moving folds. At the point when the sail is moving the downwind way, the folds are shut and won’t permit air (water if the turbine works in the water) to go through the sail. In any case, when the sail is moving the upwind way the folds will be in the vacant position and permit air (or water) go through the sail. Basically expressed, a wind turbine works the inverse of a fan. Rather than utilizing power to make wind, similar to a fan, wind turbines utilize twist to make power. The wind turns the sharp edges, which turn a pole, which associates with a generator and makes power.

Abstract: Distance matrices are used for measuring the distance between two matrices. Using Distance matrices we can generate a Latin square which is also called as Sudoku code. Latin squares have a variety of different practical applications, for example they can be used to code messages, design tournaments or generate magic squares. The theory of Latin squares is very important tool in design theory. Like much of design theory, Latin squares have various applications in statistics, finite geometries and experimental design, to name a few. In this paper, attempt is made proposed an efficient parallel algorithm for Latin square design which have desirable properties for parallel array access. These squares provide conflict free access to various subsets of an n x n array using n memory modules. A transversal of such a square is a set of n entries such that no two entries share the same row, column or symbol. It will present a general construction method for building parallel Latin square of order n ²for all n.  The proposed algorithm presents a quick method to produce a Latin square design. The simulation results of the proposed algorithm for Latin square design were compared with the traditional sequential algorithm Latin square design in terms of speedup and efficiency. The results of Latin Square design were very promising and showed a potential that this design could successfully be applied to the routing problems for conflict free data access.

Abstract: Edge-based active contour models are successful in segmenting images with intensity in homogeneity but it fail when images are poorly defined boundaries. Such as medical images. The conventional Edge stop function (ESF) use only gradient information it fails to stop gradient magnitude to rectify this problem, we formulate a group of ESFs for edge based active contour models to segment the images with poorly defined boundaries. In our proposed work, which includes gradient information and probability scores from a standard classifier. The distance regularized level set, and k-nearest neighbour’s and SVM are used to experimenting the medical images.

Abstract:   This paper presents a speed sensorless with direct torque control scheme using Space Vector Modulation (DTC-SVM) for Permanent Magnet Synchronous Motor (PMSM) drive based a Model Reference Adaptive System (MRAS) algorithm. The MRAS is utilized to estimate speed and reduced the torque ripple & improves the accurate output. In other hand the use of SVM method reduces the torque ripple while achieving a good dynamic response. Simulation results are presented and shown the effectiveness of the proposed method.
