This is a review paper on image segmentation. Basically we have tried to focus our work on image segmentation using fuzzy logic approach. In this paper we have discussed some basic concept of image segmentation and the application of fuzzy c-means algorithm in image segmentation. We have implemented this algorithm using MATLAB. This is basically the implementation part and now we are working on the efficiency respect to other fuzzy clustering algorithms which can be used for image segmentation.

Crude oil is a natural endowment to the people of Nigerian. Hence, refineries were positioned to provide finished petroleum products to both domestic use and for export. Till date, Nigeria still depends largely on the importation of petroleum products for both domestic and industrial applications. The aim of this research work therefore, is to find out the possible causes of this downward trend in the productivity pattern of our Refineries using WRPC as a case study. A survey approach was adopted in this work using questionnaires.

The paper presents the application of direct methods (field ion microscopy and atom probe techniques) to study the modification of the crystal structure of various materials at atomic spatial level after strong external exposures. On the original results shows the possibility of three- dimensional reconstruction of the elemental composition of the materials studied with atomic resolution to study the modification of the atomic structure.

Image inpainting is the process in which damaged images and unwanted objects are removed based on information gathered from surrounding areas. Different methods has been introduced regarding image inpainting i.e. Diffusion, exemplar-based inpainting etc. Different algorithms are present today but more efficient algorithms are required. In this paper, using exemplarbased method and Super-Resolution method inpainting is explained with result and Analysis.

This paper presents the findings of an experimental analysis into the effects of feed rate, cutting speed, depth of cut, and cutting environment in turning operation of Low alloy steel (En-353). Design of experiment technique, i.e. factorial method have been used to accomplish the objective of the experimental study. 23 factorial design with eight treatment combination used for conducting the experiments. It was observed that the feed rate and depth of cut was the most influential factors on the MRR and surface roughness.

This project deals with the planning, designing, and estimation of the industrial PLATE GANTRY GIRDER, located near Thuvakkudi, Trichy district. Overhead plate girder is subjected to various types of load. Girder is the critical assembly component of overhead crane. Currently research is being carried out to improve the strength structure of overhead crane girder. These new efforts help to overcome overhead crane girder failure.

This paper presents a study of the voice services usage over Adaptive Multi-user channels on One Slot (VAMOS) for improving the voice capacity. VAMOS is an extension of the Global System for Mobile Communications (GSM) standard to enable the transmission of two GSM voice streams on the same radio resource using Orthogonal Sub Channel (OSC) technique for doubling the number of users served by one cell. The concept of VAMOS is based on multiplexing two or more users at one time slot. Therefore, it is a subject for this paper to consider the downlink transmission of GSM VAMOS systems.

This paper deliberates the effects of Electromagnetic in human beings and heat (energy) in a biological or non-biological system is frequency and also discussed on the exposure of microwaves from cellular networks. While it is not certain that RF radiation generally poses any risks to human health, some reasons exist for being concerned about human health effects from the cellular phones themselves.

We estimated carbon stock of mangrove Kandelia obovata Sheue, Liu & Yong and Sonneratia caseolaris (L.) Engler planted in coastal zone of Red River Delta, Vietnam. A total of 84 10 x 10 m sample plots consisting of 39 K. obovata at 1-13 years old, 33 S. caseolaris at 2-7, 8-13 years old and mixed species of K. bovata and S. caseolaris at 10-13 years old were established. A tree census was carried out in the sample plots. Diameter at 30 cm above widening base of trunk of all trees were measured.

The present study was determine the effect of preferably used textile dye, methyl red on fingerlings of Oreochromis mossambicus as much report is unavailable on juvenile toxicity. Muscle tissue of fish were analysed for the effects of the azo dye methyl red, since it is a major target tissue for nutrient storage and is the main edible part of the fish. They affect the biologically active molecules like lipids. The fishes were maintained for a period of 40 days at two sublethal concentrations of the dye.
