Segmentation of Brain MRI Using Multilevel Iterative Discrete PSO Based SVM

Image Segmentation is an important part of image processing which can be used to separate objects in images, ignoring the effects of lights and textures. The higher resolution and better spatial discrimination of soft tissues make MRI an effective method among other medical diagnostic modalities. The existing Particle Swarm Optimization (PSO) technique is not much effective approach since the space for feasible solutions of min – cut partitioning problem is excessively large, particularly when the number of vertices is in the thousands. In this paper, multilevel segregating method is combined with discrete PSO and developed Multilevel Iterative Discrete Particle Swarm Optimization algorithm (MIDPSO) for min – cut partitioning. MIDPSO works in three steps- partitioning phase, refinement phase, and recursive partition. The classifier Support Vector Machine (SVM), based on structured risk minimization is used here. By selecting the best features in the dataset; SVM increases the performance as well as reduces the computational time complexity. The proposed technique considers local as well as global to meet the requirement of precise segmentation. The proposed method aims in classifying the healthy and pathological tissues in the MRI images with high sensitivity, specificity and accuracy in least time.

Comparison of Techniques for Diabetic Retinopathy Detection Using Image Processing

Diabetic retinopathy remains an alarming prospect to patients and disappoints doctors. Destruction of damaged retina by photocoagulation remains the primary treatment almost 50 years after its presentation. The diabetes pandemic requires new ways to deal with the pathophysiology and enhance the discovery, prevention, and treatment of retinopathy. This point of view considers how the exceptional life systems and physiology of the retina may incline it to the metabolic worries of diabetes. The parts of neural retinal modifications and debilitated retinal insulin activity in the pathogenesis of early retinopathy and the instruments of vision misfortune are accentuated. Potential intends to defeat confinements of current creature models and demonstrative testing are additionally given the objective of quickening treatments to oversee retinopathy even with continuous diabetes. Modified exudates disclosure and retina pictures gathering would be valuable for diminishing diabetic retinopathy screening costs and engaging standard examinations. We proposed the wander that applies numerical showing which enables light drive levels highlight, exudates acknowledgment, capable and revise revelation of retina pictures.

Analysis of Heat Reduction through Roof Using Innovative Insulation Technique

Buildings have significant and continuously increasing impact on the environment. The power consumption for comfortable housing is ever increasing, which is adding additional burden to the power crisis of the world. The main objective of this project is to reduce the heat transfer through the building roof by providing thermal insulation, thereby reducing the heat load on the building. Moreover, if the building is to be air-conditioned then effective thermal insulation will reduce the power consumption drastically and saves lot of energy consumption. New innovative type of insulation is proposed in this work to reduce the heat transfer through roof structure by using seashells and coconut shells. The coconut shells and seashells layer along with normal tiles will provide very good thermal insulation and it will maintain low roof bottom surface temperature when compared with the normal conventional concrete roof without insulation. Two identical experimental rooms were constructed on the top of the college mechanical engineering department block and were instrumented with thermocouple and RTD along with data logger for obtaining continuous experimental results. The amount of heat reduction provided by the insulated roof structure was calculated using analytical method. Then the cooling load requirement for air-conditioning and the corresponding energy cost per year was calculated for the new CAD lab of the mechanical engineering department. The result showed the huge energy savings potential for this innovative thermal insulation technique. The electricity savings obtained is around 39.7%.when compared with conventional concrete roof. This innovative technique for providing thermal insulation to the building is more affordable and comfortable for living.

Review On Power System Reconfiguration and Loss Minimization for an Distribution Systems

— The quickly expanding development expenses of electrical creating stations and the fuel utilized in that have concentrated consideration on the need to diminish the power and vitality misfortunes in transmission and dispersion lines. A piece of these, the another essential region in which conveyance computerization is being connected is the region of system reconfiguration (NR). Concurring this system reconfiguration it alludes to the end and opening of switches in a power circulation framework with a specific end goal to modify the system topology, along these lines the stream of energy from the substation to clients end. There are two essential motivations to reconfigure a dispersion organize amid typical method of operation. These variables are relying on the present stacking conditions, reconfiguration may wind up noticeably vital keeping in mind the end goal to wipe out over-burdens on particular framework segments, for example, transformers or line areas. For this situation it is known as load adjusting. As the stacking conditions on the framework transform it might likewise wind up noticeably beneficial to reconfigure so as to diminish the genuine power misfortunes in the system.

Study of Polymer Matrix Composite with Natural Particulate/Fiber in PMC : A Review

The evolution of composite material has replaced most of the conventional material used for automobile, aviation and other area of construction. Moreover in the field of composite, a rapid growth has been noticed in the area of natural reinforced composite material. The reason behind this growth in the research field of natural reinforced composite is the advantages of them over the other reinforcement, such as low cost, and lower environmental impact. This paper gives a review of some of developments with a discussion of the problems with the present generation natural reinforced composites and prospects for further developments. Various physical and mechanical properties of natural reinforced polymer matrix composite have been studied with the combination of different natural reinforcement with polymer matrix. The issues discussed relate to the mechanical properties in general, environmental degradation and long-term durability. The aim of this review is to provide an overview of the properties, development and performance of natural reinforced polymer matrix composite.

The Experimental Reduction of Combustion Noise at Idle Speed in a 4 Cylinder CRDI Diesel Engine by Optimizing the Fuel Injection Pressure

The design and development of modern internal combustion engines is marked by a reduction in exhaust gas emissions and increase in specific power and torque. This paper aims at the study of noise reductuion in4-stroke common rail direct injection engine at idle speed. Idle speed is basically a speed of engine when vehicle is not running i.e not in motion . Now a days , this siuation oftenly comes at redlights ,in traffic and in waiting while parked outside a business or residence etc. This paper presents a study about the effects of Fuel Injection Pressure on the combustion process. The end conclusion of the whole experiment is that reduction of noise takes place by optimizing the fuel pressure. In this experiment idle speed is 850 rpm. Then we set the fuel pressure at 200 bar at this pressure the noise is minimum which is 56 db. Further increase the fuel pressure the noise of the 4 cylinder CRDI diesel engine increases gradually at different stages like at 300 bar fuel pressure the noise of CRDI diesel engine is 60db.
