 Abstract

In this paper, conventional boost converter and high efficiency dc-dc boost converter have been taken and designed for solar energy (PV) system. The performance of two dc-dc boost converter topologies in terms of efficiency to the stand-alone PV system application has compared. It has found that the proposed improved boost converter better efficiency than the conventional boost converter. A MATLAB / SIMULINK based model is developed for high efficiency dc-dc boost converter and simulation results are presented.

Abstract: In ground improvement methods, waste materials are also used to improve geotechnical properties of soil. Waste materials such as scrap tires, ETP sludge and fly ash offers a viable alternative from economical, technical and environmental stand points. Discarded tyres are becoming globally problematic because recycling them may cause environment related problems. Thus, making use of them needs to be considered, and solutions must be sustainable. Nowadays, the waste tyres are increasingly being considered as construction material. Crumb rubber is recycled rubber produced from automotive and truck scrap tires. During the recycling process, steel and tire cord (fluff) are removed, leaving tire rubber with a granular consistency This work investigated the utilization of crumb rubber as geo materials by mixing them with low-strength soil and stabilized by cement for road and embankment construction. Two standard test methods were conducted: (1) California Bearing Ratio test and (2) Unconfined Compressive Strength test.

 Abstract

The purpose of the study was to find out the EMOTIONAL INTELLIGENCE OF TRIBAL AND NON-TRIBAL VOLLEYBALL PLAYERS. The sample for the present study consisted of 400 Volleyball Players of 16-21 years. They were taken from the Surguja District of Chhattisgarh state during the summer training camp in which 200 were tribal and 200 were non-tribal. Hindi version of Emotional Intelligence Inventory (EII-MM) developed by S.K.Mangal and Shubhra Mangal was administered to access Emotional Intelligence. It consists of 100 items the emotional intelligence of tribal and non-tribal Volleyball players of Surguja district of Chhattisgarh. It has been found that the tribal and non-tribal Volleyball players differ significantly on the measure of emotional intelligence. Non-tribal Volleyball players showed a higher level of emotional intelligence than tribal Volleyball players.

 Abstract

Independent mobility is an aspiration for every person with some or the other physical disability especially in the case of quadriplegics and multiple sclerosis. These are the patients who are paralyzed below neck and people suffering from back bone problem and knee joint problem. People with disabilities meet barriers of all type. We know that technology is manual for wheelchair but as per survey more than 70 percent of manual wheelchair users will develop shoulder pain at some point in their life. But the quadriplegic and knee joint patients cannot move any of the limbs below the neck. Hence manual and even joystick operated wheelchair is out of question for the quadriplegic patients. So, the development of voice based wheelchair will give the solution to this query about the mobility of patient and make them independent of mobility. Ultrasonic and IR sensors are integrated into this wheelchair which provides best possible and safe movement. Wheelchairs can be designed for various purpose like wheelchairs can be handled by hands, mouth, or any other functioning. Smart wheelchair is a combination of standard driver modules and collection of sensors with a user interface by using android app. This feature makes it useful for those disabled persons.

 Abstract

Wireless Sensor networks are growing areas of research. Wireless Sensor Networks are mostly used to monitor targets in the field of interest. One of the most active areas of research in Wireless Sensor Networks is that of coverage. Coverage and Connectivity are two of the most initial issue in the WSN. Coverage in Wireless Sensor Networks is usually defined as a measure of how well the sensing field is monitored or sensors are able to observe the physical space. Connectivity can be defined as the ability of the sensor to reach the data sink. In this paper we will discuss on the coverage issues in the Wireless Sensor Network. Three coverage issues are discussed in this paper.

 Abstract

The aim of the speech enhancement is to improve the intelligibility and quality of the speech. By recording the speech signal in the noisy environment, clean speech signals are degraded. Speech enhancement reduces the noise without distorting the original (clean) signal. The proposed method super Gaussian Joint Maximum a Posterior (SGJMAP) is based on gain function. In this concept, the amount of noise suppression and speech distortion is controlled in real-time based on the level of hearing comfort perceived in noisy real world acoustic environment. Objective quality and intelligibility measurement show the effectiveness of the proposed method in comparison to benchmark techniques considered in this paper.

 Abstract

In recent years, brain tumour disease is growing very quickly and it takes much more time for the same diagnosis. But here detection is done with the help of Genetic Algorithm in Non-invasive way and can save time money and life for everyone. Here we are using Medical Image Processing for the tumour detection as it is developing very rapidly. The detection, extraction and segmentation of infected tumour region from MRI (magnetic resonance image) are main concern but a monotonous and one of the supreme challenging task performed by radiologists. Processing and analysis of medical image has great importance in the arena of medicine, basically in non-invasive clinical study and treatment. The brain MRI images are acquired by using MATLAB. The pre-processing of the image is done with median filter. Analysis of filtered image is based on PSNR and MSE. This pre-processed MRI brain image is clustered by using K-clustering algorithm to find number of clusters. The Genetic Algorithm implemented to find best suitable cluster for segmentation. After segmentation morphological operations are done to remove unwanted area of the image. The geometrical features of tumour are find out using feature extraction like area, perimeter, eccentricity. To classify stages of tumour and its location whether it is in right or left lobe we are using SVM classifier.

 Abstract

Heat exchanger is important appliance in field of thermal, heat mass, fluid flow, as in nuclear reactor, steam power plant, fertilizers factory, etc. It is seen from literature that heat transfer in helical and spiral is found to be higher than U-tube due to introduction of secondary flow. For sizing of heat exchanger overall heat transfer coefficient plays very significant role. However, there is no single evidence in the literature for the comparison of overall heat transfer coefficient for same surface area under same experimental conditions which is significant for industrial heat exchanger design. Therefore present work is under taken to conduct experiments under same experimental condition for above said three different geometries under turbulent flow for same length. Experiments were carried out for different flow rates under isothermal and turbulent conditions. Overall heat transfer coefficients obtain from three different geometries like helical coil, spiral coil and u-tube coil heat exchanger of same length are reported in this work. Range of Reynolds number was kept 2000<Re<12000. From the experimental result it was found that the overall heat transfer coefficient for Spiral coil is higher than U-Tube coil and helical coil.
