This paper deals with the design and fabrication of basic Linear Induction Motor (LIM), suitable for Traction application. The different concepts of the motor that are in common with other rotating machines, are identified and studied. An Aluminum sheet lay over iron core, acts as the rotor and the stator is designed for Double Layer winding, having 2 poles. The use of Linear Induction Motors (LIM) ranges from slow moving sliding doors to high speed trains across the globe.

Today, we are familiar that, electricity is the most essential thing all around the world. Without electricity, we can’t imagine the glorious future. Each and every machine depends on the electric power supply. In the absence of electricity, not only the machines would provides the proper performance, but also the human beings feels like they are moving & reached in the ancient life. If the electricity goes off, really everything has nothing worth. Power factor is playing very important role in efficient power supply. There are certain organizations that are developing products and caring R&D work in this field, to improve or compensate the power factor. The non-functional is out of question. Recently, the technical revolution made embedded technology shape, so that it can be applied to all the fields.

The global electrical energy consumption is ascending rate, in order to meet the growing demand, there is a need to increase the power generation capacity. Nowadays, solar energy plays an important role due to limited availability of fossil fuels. The efficiency of PV is very low and power output mainly depends on solar insulation level. DC-DC converters play a vital role in many applications such as Solar Electric Vehicle, Solar Water Pumping, which mainly required boosting the lower input voltage. In order to boost the input voltage to BLDC motor and its efficient operation, various DC-DC converter topologies are used. This paper deals with two such topologies such as interleaved boost converters and CUK converter. The comparison has been made between these two topologies based on the performance of converters with resistive load, with BLDC motor and the effect of irradiance. The performance of the system has been validated using MATLAB/Simulink

Image processing plays an important role in the field of medicine. Medical imaging is a growing and challenging Field and is advantageous in diagnosing the disease. As Brain tumor is a serious and dangerous disease, medical imaging provides a proper diagnosis of brain tumor. Many techniques are available to detect brain tumor from MRI images. These methods face challenges like finding the location and size of the tumor from the brain. Reliable algorithms are required for the exact position of anatomical structures and other regions of interest through image segmentation. Already, various algorithms are developed for image segmentation. In this review paper, the basic terminologies of brain tumor and MRI images, review of various brain tumor segmentation techniques are analyzed. With increasing use of Magnetic resonance imaging for diagnosis, treatment planning and clinical studies, it has become almost compulsory to use computers to assist radiological experts in clinical diagnosis and in treatment planning.

The parameters of reliability of power distribution are the major goal lines to define the health status of any utility and its customer satisfaction. The reliability parameters of power distribution engineering are SAIDI, SAIFI, CAIDI and CAIFI, which are the primary contributors, which access the Utility-Customer dynamics in terms of credibility, accountability and satisfaction. In this paper, the reliability parameters for local Metropolitan Area Electricity Supply Company has been analyzed for the year 2014 starting from 1st January 2014 to 31st December 2014. These reliability parameters would be beneficial for the Utility to make major overhauling decision or adaptation of any latest technologies to enable a good customer relation as well as utility status. This parameter can also become the path way for implementing technology at the substation level, feeder level or at the customer end or in other words adoption of distribution system automation at the fundamental levels, basically in the form of substation automation, feeder automation and customer automation. This research activity demonstrates need for greater fault management system for improvement of distribution network reliability as well as customer satisfaction by the utility.

Maximum power point trackers (MPPTs) play very important role in photovoltaic (PV) power systems because according to the high cost and low efficiency of a PV system, it should be operated at the maximum power point (MPP) which changes with solar irradiances or load variations. So MPPT maximize the power output from a PV system for a given Atmospheric conditions i.e. irradiances and temperature, and therefore maximize the array efficiency. Thus, an MPPT can minimize the overall system cost. Maximum power point tracking (MPPT) is integrated with photovoltaic (PV) systems so that the photovoltaic arrays are able to deliver maximum available power. Maximum power point tracker (MPPT), can be used to maintain the PV array’s operating point at the MPP. This paper presents an improved maximum power point tracking (MPPT) algorithm of a PV system under changing atmospherics conditions. The proposed MPPT is based on the perturbation and observation (P&O) strategy.
