6 Replacement of Coarse and Fine Aggregate by waste Ceramic Tiles and Ceramic Powder in Concrete
B.Magesh, M.Jayagopal
Abstract - Concrete is an advanced material in civil engineering. It is binding material made with cement, fine aggregate, course aggregate and admixtures in some cases. Nowadays developments of construction field, the worldwide consumption of natural materials is very high and at the same time production of solid waste from the destructions and production units are also very high. Extensive use of concrete leads to the lack of natural materials. Because of this reasons the recycle of destructions wastes and solid waste from the production of came in to the picture to decrease the solid wastes from destructions and production units and as well as to decrease the lack of natural basic materials. The current option of dumping for this type of unused is landfill. Unavailability of standards, avoidance of risk, lack of knowledge and experience led to there being no active usage of ceramic wastes in construction. Ceramic wastes are classified as non-recyclable wastes in South Africa, except for the normal use as filling material. Based on research regarding ecological Construction and Destructions (C&D) wastes, ceramic wastes have the potential to be used in concrete production. There are no guiding principle and criteria to the usage of waste in solid. In addition, the local industry does not have knowledge and experience to utilize the material.

Himasekhar sai B.V
Abstract - Functionally Graded Material (FGM) belongs to a new class of advanced material characterized by gradual variation in composition and the mechanical properties. The overall properties of the FGM are unique and different from the individual material used. Previous investigations show that various techniques such as powder metallurgy, centrifugal method, vapor deposition techniques, solid freeform fabrication methods and friction stir processing etc. have been used to fabricate the FGM. In order to overcome the control over the composition, the present study presents a method to fabricate Functional Graded Material using Friction Stir Processing (FSP) and hole drilling electrical discharge machine (EDM). Holes are drilled on an aluminum plate and filled with Alumina nano-particles of size (<50nm) and stirred using FSP. A mathematical model for positioning of holes in order to acquire a range of maximum to minimum composition of nano particles over a given length is presented. By aligning FSP seem tool center to hole center, multi-pass FSP is carried out to understand the material flow and mixing. The hardness variation along the direction parallel to the surface and perpendicular to the surface and along the depth is measured. The mathematical model is applied to different combinations of composition ranges and is evaluated under different conditions.

Abstract - Although the use of spraying robotized systems for interior painting was already shown to be feasible and convenient, a lot of experiments must be carried out in the future to deliver a highly autonomous robot for interior painting. The primary aim of the project is to design, develop and implement Automatic Wall Painting Robot which helps to achieve low cost painting equipment. Despite the advances in robotics and its wide spreading applications, interior wall painting has shared little in research activities. The painting chemicals can cause hazards to the human painters such as eye and respiratory system problems. Also the nature of painting procedure that requires repeated work and hand rising makes it boring, time and effort consuming. When construction workers and robots are properly integrated in building tasks, the whole construction process can be better managed and savings in human labour and timing are obtained as a consequence.

20 Enhanced VLSI Architecture of Partial Product Generator using Redundant Binary Modified Partial Product Generator Method
J. Ravichander, Gunde Mounika
Abstract - Adders are the key component of the arithmetic unit, particularly quick parallel addition. Redundant Binary Signed Digit (RBSD) adders are intended to perform high-speed arithmetic operations. For the most part, in a high radix adjusted Booth encoding calculation partial products are lessened in augmentation process. A redundant Binary (RB) representation can be utilized when designing high performance multipliers, because of its high measured quality and convey free option, The traditional RB multiplier re quires an extra RB partial product (RBPP) row, on the grounds that error correcting word (ECW) is created by both the radix-4 Modified Booth encoding (MBE) and the RB encoding. This brings about in an extra RBPP accumulation stage for the MBE multiplier. Another RB altered partial product generator RBMPPG is proposed; it expels the additional ECW and consequently, it spares one RBPP RBPP accumulation stage. In this way, the proposed RBMPPG creates less halfway item pushes than a regular RB MBE multiplier. Simulation results show that the proposed RBMPPG generates fewer partial product rows than a conventional RB MBE multiplier. Simulation results show that the proposed RBMPPG based designs significantly improve the area and power consumption when the word length of each operand in the multiplier is at least 32 bits.
21 Regression Modelling and GRA, RSM Comparison Between Parameters and Performance Characteristics in a TOBV
Vinayak Balehittal
Abstract - Triple offset butterfly valves are widely used in hydraulic, sewage, oil and gas pipelines. Seating torque and deformation of the disc are the important characteristics to be considered during the assessment of flow performance of butterfly valves. In order to minimize the leakage in pipelines, the offset concept was introduced in butterfly valves by designers. Even though some of the researchers have studied the effect of offset on sealing characteristics of butterfly valves, studies considering the effect of offsets on the performance characteristics such as seating torque and deformation of the disc have not been reported yet. Hence the present project focuses on parametric study of triple offset butterfly valves in order to maximize the flow performance and hence achieve optimal combinations of valve parameters. The overall objective of the study is to evaluate the effect of offset in a TOBV on the characteristics of the valve like seating torque and disc deformation. The geometry considered for this purpose is TOBV DN100 CLASS150 valve. Triple offset butterfly valve CAD model was generated using SOLIDWORKS V 13. The same CAD model was then imported to ANSYS Workbench platform to conduct static structural analysis of the valves. Simulation runs were designed based on Taguchi's Orthogonal Array approach. The offset having the maximum influence on seating torque and disc deformation were evaluated. A regression model for seating torque and disc deformation was also developed indicating good correlation. The optimal combination of offset levels for minimum seating torque and minimum disc deformation were also evaluated through Grey Relation Analysis and Response Surface Methodology. Both were found to be in good agreement.

K. Bhagya Lakshmi, V. Sugunamma, J V Ramana Reddy
Abstract - Heat source/sink may change the heat distribution in the fluid which consequently affects the particle deposition rate in the system such as semiconductors, electronic devices and nuclear reactors, etc. In view of this, we studied the impact of non- uniform heat source/sink on the magnetohydrodynamic flow of Sisko fluid over a stretching sheet with cross diffusion effects. The convective type boundary condition of temperature is taken into account. The transformed set of non-linear ordinary differential equations is solved by using Runge-Kutta based shooting technique. The influence of various flow parameters on velocity, temperature and concentration fields is presented and analyzed through graphs. Also, the wall friction factor coefficient and the rate of heat and mass transfer coefficients are derived and discussed through tables. It is noticed that thermo-diffusion and diffusion-thermo effects show significant effect on fluid flow.

Pralhad D. Talmale, Rufaiza. P. k. Quazi, Adarsh R. Dahat, Namita V. Wankhade, Ashwini B. Nagdevte
Abstract - The losses at distribution level contribute a major portion of power system losses. Proper sizes of shunt capacitors in unbalanced radial distribution systems can reduce some portion of this loss and can improve the voltage profile of the feeder section. The PSO-DV approach consists of classical Particle Swarm Optimization (PSO) and differential evolution approach in combination. For capacitor placement problem, the power losses occurring in the system are minimized while voltage profile is improved. Initially to find site of capacitor allocation, candidate nodes using sensitivity analysis reactive power injection is done. Then PSO-DV is implemented to find size and number of capacitors considering minimization of power losses as an optimization problem.

Abstract - AA6061 alloy has Excellent joining characteristics, good acceptance of applied coatings; this combines relatively high strength, good workability, high resistance to corrosion, and good weldability. H13 Hot Work Tool Steel has High hardenability, excellent wear resistance hot toughness, and good thermal shock resistance all the mentioned properties make it a perfect selection for friction stir welding tool and this material can tolerate some water cooling in service. Nitriding will improve hardness, but can diminish shock resistance if hardened layer is too thick. HSS-M2 and D3 are also similar tool steels which are considered in this study as FSW tool materials for experimentation. Current work deals with the experimental investigation on effects of post weld heat treatment on the mechanical properties of friction stir welded joints of Aluminium alloys. In order to study the effect of post weld heat treatment a design of experiment is conducted and a set of experiments are defined. Experimental trials were conducted with three different tool materials of different hardness with and without post weld heat treatment. Mechanical properties are studied as per the standard procedure defined by American welding society. Post weld heat treatment improves the ductility of the weld joints thus increases the flexibility to use the welded joints in many new applications like explosion forming.
28 Modified Dynamic Power Management an Integrated Approach for Lifetime Enhancement of Wireless Sensor Network (M-DPMM)
R. Augustian Isaac, Dr.S. Lakshmi
Abstract - Routing protocol is one of the efficient methods of enhancing the lifetime of the network. Life time of the sensor node has to be increased in order to increase the battery life which does not cause frequent changing of batteries in the physical network and hence the network could be made as less maintenance network and cost effective. Multipath routing is one of the best routing path protocols for lesser energy consumption as it involves even repair of the selected path. The only challenge is this type of routing is selection of neighbour nodes. Hence proper selection of neighbours involves a modified approach where neighbour is selected based on fuzzy logic techniques rather than traditional techniques.
