The objective of this thesis is to use coconut fibers as admixture and fly ash as a partial replacement of cement in M20 grade concrete. The compressive strength, split tensile strength and flexure strength of concrete at the age of 7, 14, 28, 56 and 90 days in normal water and sea water are tested and the comparison of strength of concrete cured in normal water and sea water are made. Based on the results there is an increase in compressive strength, flexural strength and split tensile strength of concrete is observed on 30% fly ash as a replacement and 5% coconut fibers as an admixture in cement when the specimens are cured in normal water. The compressive, flexural, split tensile strengths of concrete are tend to decrease which are cured in sea water when compared to the specimens cured in normal water.

Pages: 78 - 83
Composite materials combine two dissimilar materials to attain better properties. Composite materials are as mature as jute natural fiber as reinforcement material by polymer materials matrix. A specimen product of such a composite is developed during layer by layer method at a certain temperature to go with the processes. The composite is tested for its mechanical properties using predictable testing machines and the results were recorded. The composite specimen is analyzed with ANSYS software for its mechanical properties.

The earth’s atmosphere has definite limits, as it is not boundless. Life water courses, it has limited capacity for its self-purification. Industrialization and urbanization result in release of gaseous pollutants into atmosphere, presuming it to be and endless reservoir. The most common gaseous contamination in the urban atmosphere are sulphur dioxide, carbon mono-oxide, ozone and oxidants, oxides of nitrogen, hydrocarbons and aldehydes. Except under special circumstances, the carbon dioxide is not considered as and atmospheric contaminant, because of its role in the photosynthesis of green plants. One should know about composition and structure of the atmosphere, sources of air pollution- Natural or Man-made, types of Air pollutants, and its unit of measurement and effects of air pollution on vegetation, human health.

Pages: 89 - 93
Wireless sensor networks becoming popular day by day due to their flexibility and convenience of use in wide variety of applications, however flexibility and increased convenience of a Wireless sensor network comes at a price and introduce new security hazards. Security is fundamental to the acceptance and use of sensor networks for numerous applications. Security solutions applicable to wired networks do not directly applicable to WSN. To develop suitable security solutions for a WSN environment, we must first understand how these networks can be attacked. This paper presented a survey on some of common routing attacks and their countermeasures in WSN.

A New Collaborative Approach for Image Fusion using SWT-LP Algorithm

Pages: 94 - 99
Image Fusion is a process of attaining relevant information from the multiple images of same scene. More than one image is combined to form a single image which contains better description of the scene. Any of the individual input images are not capable in providing that much informative information which can only present through a fused image. Basic requirement of image fusion is for high resolution on panchromatic and multispectral images for better visibility. Image fusion process has used to remove the noise from the images. As noise can deteriorate the actual quality of the image thus it is required to remove noise from the acquired image. There are numerous methods of image fusion has introduced till now such as DCT, DWT, SF but due to the issues like quality degradation and edge preservation directs a new technique which is a combination of SWT and Laplacian pyramid Fusion. Experiments have been performed which shows that proposed technique has better efficiency as compare to traditional techniques.

Effect of Burnishing Force on Surface Roughness and Hardness of Low Carbon Steel Spur Gear by using Diamond Gear Burnishing
Chhabildas M Gajare ; Dr. U. M. Shirsat
Mechanical Engineering
Year: 2016, Volume:3, Issue : 6
Pages: 100 - 104
Gear Burnishing is a cold working surface finishing process in which the work gear is rolled in tight mesh with hardened and highly accurate smooth gears. When contact stress between gear teeth increases the yield point stress of the material, plastic deformation occurs that reduces surface irregularities improving surface finish and induces useful residual compressive stresses. Gear burnishing if carried out properly results in improvement in metallic surface properties such as surface finish, surface hardness, wear resistance, corrosion resistance and fatigue life. The involute spur gears of AISI 1018 and AISI 1020 are burnished by diamond gear burnishing tool for fixed values of cycle time and speed without coolant. The burnishing force is varied to investigate its impact on surface roughness and surface hardness of gears. The spur gear is rolled in mesh with hard diamond coated gear at 300 rpm for 30 seconds in clockwise direction and then for another 30 sec in anticlockwise direction on standard diamond gear burnishing machine. Considerable effect of burnishing force on surface finish and micro hardness of spur gear of is observed due to burnishing.

Pages: 105 - 113
As we are aware that the number of accidents at railway crossing has been increasing lately, more precautionary measures are being undertaken. Accidents take place either due to the absence of crossing gates, or due to impatience and carelessness of pedestrians. There are many places where the railroad crossings are open, without any gates. This becomes an open threat to the people or vehicles who wish to cross the railroad. Whereas, there are places where the crossing gates at railroad is being controlled and managed by a guard. In such cases, threat may arise due to carelessness of the guard. So, our project aims at automating this process. Automatic Railway Gate Control (ARGC) is managed and controlled by microcontroller 8051 and is more reliable since there is no human intervention in the process. Our model, most primarily, is different from others in terms of the programming method and considering various possibilities that the actually railroad crossing system encounters. We have programmed 8051 using assembly language program (.asm). Infrared (IR) sensors are used which senses the presence of train and conveys the information to 8051. 8051 is programmed accordingly to open or close the gate whenever required. Also, the steps for creating hex file from the program are elaborated. Keil uvision3 is being used to create the hex file.

About all the countries are facing the economy problem during the paucity of petroleum and almost all petroleum demand through imports. A Substitute for Diesel engine fuel is of huge consequence to the Fuel scarcity. In this study Experiments were carried out in the diesel engine by using water melon seed oil and Blended watermelon seed oil. Three blends of watermelon oil such as 25%, 50%, 75% and 100% are used in this experimentation. The Blended oil is heated externally up to boiling temperature 67 o C before injecting into the test cylinder. Engine performance is very high at the same time lowest specific fuel consumption were attained while using the Blended fuel. The experimental results are discussed the oil content of Water melon seed oil remarkably high. Lesser NOX where induced while in 100 % of bio diesel used in the engine and very stumpy Carbon dioxide (CO) where induced while the engine operates at maximum load. Comparatively the blended fuel significantly improves the Engine performance and Break thermal efficiency to the other Blended fuels. Hence the Blended Fuel is Very suitable to the Diesel Engine to operate the engine at utmost consignment.

Pages: 119 - 122
Supplier selection plays a vital role in managing the supply chain. Recent trend on sustainability has made the selection more complex. Decision support tools and methodologies can help organizations and supply chain managers make more effective decisions. Many tools have been developed with a variety of formal modeling techniques. The techniques may be limited for a various reasons. To help in advance sustainability discussion into the supplier selection modeling area, we expand on a novel approach first introduced by Li, Yamaguchi, and Nagai (2008). Our expansion and contribution includes introduction of additional levels of analysis and application of this methodology, the explicit consideration of sustainability attributes, and insights into the technique with some sensitivity analysis. Thus an review is given in this paper.
