1 Brain Tumor Detection MRI Image Using Fuzzy K-Mean
K. Chawla and Prof. Sanjeev Shrivastava

ABSTRACT - In the last decade different types of new tumor cases are available. They may be as mass in brain or malignant over the brain. Suppose if it's a mass then K- means that algorithmic rule is enough to extract it from the brain cells. If there's any noise are present within the Magnetic resonance image it's removed before the K means that method. The noise free image is given as a input to the k-means and tumor is extracted from the imaging image. so segmentation victimization Fuzzy C means that for correct tumor form extraction of malignant neoplasm and threshold of output in feature extraction. Finally approximate reasoning for scheming tumor form and position calculation. The experimental results are compared with different algorithms. The stage of tumor is based on the area of tumor. The noise free image is assumed as an input to the k-means and tumor is removed from the MRI image. The experimental results are compared with other algorithms. The final output of enhanced K-mean calculated area with improved accuracy is shown in the proposed work. The accuracy is observed with the help of Edges of proposed K –Mean algorithm.

2 Performance Analysis of SHEPWM based Single Phase VSI
Divyanshu Vimal and Prof. Santosh Kumar (Head of Department)

ABSTRACT -Inverter is a device which is used for converting DC power into AC. The basic constitute of all inverter is power switch. All switches are based on the gate pulse. The technique used for on or off the switches is call firing of the switch. There are many techniques used for the getting the switching. In this paper discuss the single phase H bridge inverter with selective harmonic elimination based PWM technique. The whole work is simulated in MATLAB software for experimental demonstration. The Newton-Raphshon method is used for optimising the angle selection of five harmonics elimination. The result show the elimination of the harmonics in the work

3 Performance Analysis of 31 level MLI with Reduced Switch Count
Kundan Kumar Jha and Prof. Santosh Kumar (Head of department )

ABSTRACT -Multilevel inverter are well known for power industries and have tremendous capability at medium and high voltage application. With the increasing the output level these inverter required more and more switches in the circuits. Due to increasing the number reduce the efficiency of the inverter also its driver circuit becomes more complex. To solve that type of problem it required reduce count of the switch. In this paper a 31 level multilevel topology is discussed with their switching pattern. The mathematical operation is also discussed. The proposed topology is simulated in the MATLAB software. The THD of the voltage and current for inductive load is discussed.
Keywords— DC to Ac, MLI, Asymmetric inverter, reduce count and PWM strategy etc

Sitaram Chouhan, Prof. C.S. Sharma and Prof. Sudhir Sharma

ABSTRACT -In this Paper focus on design and implementation of the new topology in a multilevel inverter with a reduction harmonic, size, cost in higher efficiency the main objective of this work a novel three-phase inverter with applicable in induction motor drive in medium voltage application. The main advantage of the new topology is to reduce the THD (Total Harmonic Distortion) lower electromagnetic interference generation and higher output voltage for applicable induction motor drive. This work describes a reduce harmonic in a three phase seven level inverter circuit with new level shift pulse width modulation (LSPWM) scheme is purposed. This topology is a combination of a three level inverter and a full bridge flying capacitor inverter circuit. The three level inverter parts elaborates undesired negative and positive spikes as generated by a conventional three level inverter. The performance of the purposed three phase seven level inverter is studied for different modulation indices with induction motor load and show in speed torque characteristics, seven level output voltage wave form is shown in FFT window MATLAB/ simulation result are present.

5 Smart and Secure Railway Transport System
Dr. Sridhathan C, Dr. M. Senthil Kumar and Mr. G. Rajesh Krishna

ABSTRACT - In developing countries like India, human population increases rapidly. There is a huge demand for transportation such as buses, trains, flight etc. To reduce the congestion, Indian Railways are commuting trains which ply nonstop. Because of continuous running, there may be a chance fire due to short circuit in electrical system or wear and tear of brake systems or pantry. We propose a novel system here, where the human loss due to such fire accidents can be reduced. The system designed alerts the passengers in case of fire, sprinkles water on the coach got fired, detaches the coaches and reduces further spreading of fire and alerts the authorities by sending message. This proposed method can be implemented in the Indian railways to reduce the causality due to fire in an efficient way.

6 Dynamic Clustering and Threshold Based Routing Protocol for Wireless Sensor Networks
Garima Tiwari (M. Tech Scholar) and Prof. JyotsnaSagar

ABSTRACT -Wireless sensor networks are finding applications in diverse walks of life such as defence, maritime research, heavy industries etc. Generally such networks need to transmit data continuously over a period of time in a specific coverage are which makes their lifetime limited. Lifetime enhancement in wireless sensor networks has long been an active area of research. There are several approaches that have been proposed for the lifetime enhancement of wireless sensor networks. In this paper a thresholding approach has been in conjugation with dynamic clustering of sensor nodes. The approach uses two thresholds which minimize the number of transmissions thereby saving energy. The dynamic clustering reduces the burden on a particular data node. The performance of the proposed system has been evaluated based on the network lifetime i.e. the analysis of number of rounds versus number of nodes. Also the number of dead nodes and the average energy of nodes with respect to the number of rounds as also been analyzed. It has been shown that the proposed technique performs better than previously existing systems.
