M.Rajiv, M.Arun Pandiyan, G.Sofia, M.Abinaya
In India, bricks are usually made up of clay, and are generally produced in traditional, unorganized small scale industries. Brick making consumes larger amount of clay which leads to top soil removal and land degradation. To avoid all this environmental threats an attempt was made to study the behavior of bricks manufactured using, waste materials from sugarcane industrial waste. Recycling of such waste as raw material alternatives may contribute in the exhaustion of the natural resources and reduction in waste disposal costs. In this project we choose sugarcane bagasse ash (SBA) and press mud in ordinary Portland cement (OPC) stabilized bricks. The brick was manufactured of size 25cm x 12cm x 6.5cm. The blocks were named as 4, 6 and 8 then it is added with SBA and press mud by weight of dry soil, then the bricks followed by curing for period of 28 days. The test like compressive strength, water absorption test, shape and size test in accordance with Bureau of Indian standards (BIS) specifications by also considering the cost.

T.Prakash, B.Radhika, V.Suwathy, P.Dinesh
Water is the most important element to support life. Water scarcity is the major problem faced by many countries in recent days. Even though two-third of the world is covered by water, fresh water available to fulfill the day-to-day needs remains scarce. During the last century global human population increased above 6.3 billion. This drastic increase in human population leads to the severe shortage of water supply which in turn greatly affects the food production. In addition, Due to the increased use of ground water, ground water sources are depleting which affects the nature drastically. The death rate due to water scarcity increases nowadays. There is an importance to find the alternative fresh water sources immediately. Atmosphericair usually contains more number of gases like nitrogen, oxygen, hydrogen, water vapors and 1% to 4% of water molecules. The goal of our project is to create a portable device which serves as a suitable method to obtain the fresh water. This device extracts the water molecules present in the air and condensing them to produce the drinking water.

R.Arjun, P.Dinesh, K.Karthick, S.Melvin Richard, S.Balakrishnan, S. Priyarega
The world is confronted with the twin crises of fossil fuel depletion and environmental degradation. The indiscriminate extraction and consumption of fossil fuels have led to a reduction in petroleum reserves. Petroleum based fuels are obtained from limited reserves. These finite reserves are highly concentrated in certain region of the world. Therefore, those countries not having these resources are facing a foreign exchange crisis, mainly due to the import of crude petroleum oil. Hence it is necessary to look for alternative fuels, which can be produced from materials available within the country.

Adressing the un-reachability problem using greedy algorithm in WSN
Rajeeve Dharmaraj, Chengathir Selvi Murugesan, Prathiba.T
The unreachability problem (i.e., message is not received by the receiver) that exists in the greedy routing algorithms has been studied for the wireless sensor networks. Some of the current research work cannot fully resolve the unreachability problem, while there exists other schemes that can guarantee the delivery of packets with the excessive consumption of control overheads. Moreover, the hop count reduction (HCR) scheme is employed as a short-cutting technique to reduce the routing hops by listening to the neighbor’s traffic, while the intersection navigation (IN) mechanism initiates to obtain the best rolling direction for boundary traversal with the adoption of shortest path criterion. In order to maintain the network requirement of the propound RUT (Resource Utilization Time )scheme under the non-UDG(Unit Disk Graph) networks, the partial UDG construction (PUC) mechanism is proposed to transform the non-UDG into UDG setting for a portion of nodes that facilitate boundary traversal. These three schemes are integrated within the GAR protocol to further enhance the routing performance with reduced communication overhead. The proofs of correctness for the GAR scheme are also given in this paper.

R.Ganesh, A.Sheerin Farzana, P.Ponkarthikeyan, J.Jacob
In this industrial world, recycling material plays an important role to preserve natural sources. The main focus of this research is to study the strength of paver block using waste industrial materials. Metal foundries use large amounts of molding sand for casting process. Foundries successfully recycle and reuse those sand many times. The foundry sand is removed from foundry when the sand can be no longer reused. Foundry sand can be used in concrete to improve its strength and other durability factors. Rice Husk Ash (RHA) is the pozzolanic waste generated from Rice milling Industries. Blending of a large amount of RHA is being done in large extents in the manufacture of cement and cementitious products. This paper deals with the study of strength and durability characteristics of RHA and WFS replaced paver block. Cement concrete cubes were casted to determine the optimum percentage replacement of cement and fine aggregate with RHA and WFS. Optimum results were found for the replacement of 15% RHA with total mass of cement and 20% WFS with total mass of fine aggregate. From the obtained optimum results, paver blocks were casted with 15% cement replacement with RHA and 20% sand replacement with WFS. Tests were performed for water absorption test, flexural strength, impact test, abrasion resistant test, compressive strength and split tensile strength for replacement levels of rice husk ash and waste foundry sand at different curing periods (28-days & 60-days). Test results shows increase in strength and durability performance of the paver blocks. From the test results it can be concluded that Manufacturing of bricks and paver blocks using combination Rice Husk Ash and Waste Foundry Sand is feasible and economical.

Influence of carbon percentage on the microstructure of dual phase steel
An investigation aimed at determining the importance of Carbon percentage in the microstructure development of Dual Phase steel is carried out by intercritically annealing the different samples of low carbon steels which consists of different percentage of carbon (0.16%, 0.18%, 0.20%). The samples are heated in muffle furnace to above Ac3 temperature (920oC), soaked the sample for 30 min and quenched in Ice brine solution to get complete martensitic structure. Later the samples are inter critically annealed at 740oC, 760oC, 780oC, 800oC, 820oC (between Ac1 and Ac3) for 60 minutes and quenched in oil at room temperature. Microstructure examination revealed that steel containing 0.18% C yields a better microstructure which consists of around 46% Martensite and remaining Ferrite and minute amount of retained Austinite, which is a good combination of Strength and toughness. The uniaxial tensile test results shown that at Specimen containing 0.18%C with 46% Martensite content yielded maximum Tensile strength with comparatively higher toughness Microhardness test shows that hardness increases with increasing in Carbon percentage and has higher values at 0.18%C.

Characterization of aluminium 6061 matrix reinforced with red mud with different weight fractions
Aluminium matrix composites (AMCs) are potential light weight engineering materials with excellent properties. The present investigation aims to evaluate the properties of red mud particulate reinforced with aluminium 6061 metal matrix composites. Red mud particulates in different weight fractions are under dry condition. Composites are prepared by Stir casting method. The main objective of this study is to develop red mud reinforced aluminum composites using stir casting and the powder metallurgy process. Red mud is a material which is obtained as industrial waste during the production of alumina by Bayer’s process. Red mud could be used as reinforcement for the production of aluminum composites. Using varying wt. % of reinforcement, the aluminium composites are fabricated by stir casting method. Due to technological advancements, it is possible to use Nano sized reinforcement in Al matrix. Nano sized reinforcements enhance the properties of Al matrix compared to micro sized reinforcements. With increasing volume fraction, more loads are transferred to the reinforcement which results in a higher yield strength, ultimate tensile strength and bending force and ductility to the Al-alloy/Red mud composites. This project is focused on overview of development in the field of Al based metal matrix with Nano aluminium based composites.
Evaluation of mechanical working characteristics of nitinol based shape memory alloys with Fe ternary additive
The influences of Fe-addition on phase transformation behavior, mechanical properties and microstructure of Ti50Ni50-xFex alloys were investigated by means of optical microscopy, Differential Scanning Calorimetry and X-ray diffraction (XRD). Results indicate that, as a substitute for Ni, Fe added to TiNi alloys can dramatically decrease the martensite transformation temperature and R phase transformation and martensite transformation are accordingly separated. The results show that TiNiFe alloys exhibit two-step martensitic transformation. The start temperature of martensitic transformation increases sharply from 245 K to 267 K when 4 % Fe is added in, and then decreases gradually if Fe content further increases. The hardness of TiNiFe ternary alloys before heat treatment is constant for up to 4% of the composition and suddenly increases for 8% composition and also it behaves same for heat treated specimens because of formation of equilibrium precipitates Ni3Ti formation.
