Cement concrete is a versatile building construction material in civil engineering and it is also one of the world’s most extensively used construction material around the world in almost all construction projects and in many construction applications. Construction activities and projects are increasing around the world which has resulted into the excessive extraction and utilization of naturally available materials like natural river sand, stones and rocks, lime, clay, water etc. Currently the problems faced by the use of cement concrete includes high demand of cement concrete, cost of cement and concrete making materials, pollution, excessive extraction and utilization of natural river sand and stones, water etc. Because the sand is being extensively extracted from the river bed deposits, it is depleting at a faster rate. Hence it is necessary to find an alternative material such as industrial waste slag and waste pieces of stones from the stone quarries in the cement concrete production. This dissertation work deals with the study of partial replacement of natural fine aggregate by steel slag and natural coarse aggregate by waste limestone aggregate in M20 grade of cement concrete. Steel slag is a waste by-product obtained from the iron and steel plants and waste limestone aggregates are the waste broken pieces of limestone obtained from the limestone quarries. In this work, we have made an attempt to study the compressive, split tensile and flexural strength of M20 grade cement concrete by using steel slag and waste limestone aggregate as partial replacement to fine aggregates and coarse aggregates. The compressive strength test is studied for 7 and 28 days of curing period and the split tensile and flexural strength is studied for 28 days of curing period.

Recently, immense interest was paid to new technologies dealing with environmental aspect. Upholding of natural resources such as natural fibres, resins, and composites lead the upcoming manufacturing industry to search and scrutinize ecofriendly materials. The use of composites in manufacturing equipment and products is taking a very important space in the industry. In general these materials have unique characteristics when analyzed separately from constituents which are part of them. However it is known that care must been taken in their manufacturing as the use of appropriate process and the composition of each element, in addition to the adherence of fiber, which is a major factor in obtaining the final mechanical strength of the product one should also take into account whether the composites are environmental friendly. For this reason, the paper focus on manufacturing a bio composite fiber, using natural fibres as strand (cotton fibres, flax fibres and raw flax) which is a hybrid form of reinforcement in the soya resin phase to form a composite, seeking to improve the mechanical behaviour among its class of materials.

Bigdata privacy preservation is one of the most disturbed issues on the current industry. Data privacy issues need to be addressed urgently before data sets are shared on cloud. Data anonymization refers to as hiding complex data for owners of data records. In this paper investigate the problem of big data anonymization for privacy preservation from the perspectives of scalability and time factor etc. At present, the scale of data in many cloud applications increases tremendously in accordance with the big data trend. Here propose a scalable Two Phase Top-Down Specialization (TPTDS) approach to anonymize large-scale data sets using the MapReduce framework on cloud. For the data anonymization-45,222 records of adults information with 15 attribute values was taken as the input big data. With the help of multidimensional anonymization on map reducing framework, here implemented the proposed Two-Phase Top-Down Specialization anonymization algorithm on hadoop will increases the efficiency of the big data processing system. In both phases of the approach, deliberately design multidientional MapReduce jobs to concretely accomplish the specialization computation in a highly scalable way. Data sets are generalized in a top-down manner and the better result was shown in multidmientional MapReduce framework by compairing the onedimentional MapReduce framework anonymization job. The anonymization was performed with specialization operation on the taxonomy tree. The experiment demonstrates that the solutions can significantly improve the scalability and efficiency of big data privacy preservation compared to existing approaches. This work has great applications to both public and private sectors that share information to the society.

The power can be generated in the combustion chamber of an automobile. The combustion chamber is the place where the charge burns in. The charge i.e. air and fuel at various proportions depending upon the accelerations made is sent through carburettor which is compressed inside the combustion chamber with to and fro moments of piston within the top and bottom dead centres. After the combustion, the burnt charge exerts a lot of force on the piston. The piston plays various roles in compressing the charge and in transferring the produced power to the crankshaft. During this process, always the piston is in contact with the charge. The burnt charge has temperature about 12000C. The heat flows into the piston. So the piston should have sufficient mechanical strength to with stand the force acting by the explosion and the piston should be thermally stable to with stand the heat flow into the piston. The piston is cooled by providing cooling fins external to the surface of Combustion Chamber. In this paper the thermal analysis of the piston is done by modelling the piston with aluminium alloy. The thermal analysis was analysed using software ANSYS. It is found that, the aluminium alloy piston is having the sufficient thermal stability to with stand the high temperatures.

This paper was concerned with an experimental study of parabolic trough collector designed and manufactured. A parabolic trough solar collector uses three reflecting material stainless steel, aluminum foil and mirror glass strips affix on cloth in the shape of a parabolic cylinder to reflect and concentrate sun radiations towards an absorber tube located at the focus line of the parabolic cylinder. The receiver absorbs the incoming radiations and transforms them into thermal energy, the latter being transported and collected by a fluid medium circulating within the absorber tube. To improve performance and reduce costs direct steam generation in the collector has been proposed. The Designing and Fabrication of parabolic trough solar water heater for water heating was executed, the procedure employed includes design, construction and testing stages. The model which is made up of reflector surface, reflector support, absorber pipe and a stand with manual tracking arrangement was fabricated using locally sourced material for rural applications point of view. In this paper the efficiency of parabolic trough collectors is compared on the basis of different reflecting surfaces (current SEGS plants). The model is based on absorber fluid temperature so it can be used to predict the performance of the collector with any working fluid. We determined the performance of PTSC on the basis of different reflecting surfaces.

Apoptosis is an important pathogenic mechanism in renal diseases, during development and injury. Lethally injured cells may die by either necrosis or apoptosis, depending on the severity of the injury. Severe renal ischemia results in acute tubular necrosis, chronic low grade ischemia leads to apoptosis in renal tubular cells. Cyclosporine-induced apoptotic cell death is closely associated with activation of proapoptotic genes and altered regulation of apoptosis-regulating genes. Cyclosporine A (CsA) has considerably modified the graft survival in solid organ and bone marrow transplantation. Renal toxicity is the major adverse effect of chronic CsA administration. Deterioration of renal function and renal histopathology are the basic elements of the diagnosis. In the present study, the lethal pathways activated by cyclosporine A (CsA), a nephrotoxin that induces caspase-dependent apoptosis in tubular epithelium, were explored. The Tubular cell apoptosis is the major contributing factor to the pathogenesis of renal injury. The understanding of the CsA renal effects is not only a research interest, but also clinically important in developing a strategy in the prevention and treatment of the disease. In this contribution, we will discuss this effect and its significance for the mechanism of action of Bax, cytochrome c, caspase-3 in renal tubular cells, an important checkpoint of the apoptotic process.

Flexible manufacturing systems (FMS) are production systems consisting of identical multipurpose numerically controlled machines (workstations), automated material handling system, tools and load and unload stations, inspection stations, storage areas and a hierarchical control system. The latter has the task of coordinating and integrating all the components of the whole system for automatic operations. The basic problem in FMS operations is scheduling of jobs on the different machines. This problem can be solved through various approaches. One of the techniques is fuzzy logic. This technique answers a problem in a probabilistic way by values ranging between 0 and 1.in my problem, I have taken two priority conditions-job priority and route priority and the scheduling has been done accordingly. The results are compared with shortest processing time and more time is consumed using shortest processing time technique. This shows that fuzzy scheduler can be used as one of the powerful tool in FMS scheduling problem.

Suspension system has to perform complexity requirements, which includes road holding and equality, driving pleasure, riding comfort to occupant. Riding pleasure depends on vertical acceleration, with main objective to minimize vertical acceleration. The force transmitted by the deflection of tires to the unsprung mass is known as the Tire-Dynamic Force (TDF). The force should be considered while designing the suspension system. The TDF can cause vehicle instability and increase in the sprung mass acceleration. The objective of this research work is to minimize the TDF by optimum suspension design so that minimum vertical accelerations would be experienced by the passengers. To minimize the vertical acceleration, mathematical model of 2-DOF Quarter car model is considered for passive suspension system. Its equation of motion is formed with correlating objective function. Thus having objective function to, minimum weighted root mean square accelerations as per ISO 2631, viz. formulated for optimization. spring stiffness and damping coefficient are used as variables during optimization. The Genetic Algorithm is implemented as optimization tool with above mentioned objective function. The optimization results obtained were simulated and are compared with classical values. It is observed that the Seat acceleration, using optimized values, is reduced by 8.76% compared to the classical values. From experimental validation main objective function of Tire dynamic force value reduced from 2300 N to 2100 N, it is decreased by 8.69 % and Seat acceleration reduced from 34.9176 m/s2 to 32.0121 m/s2 after replacing the conventional by optimized strut. Thus provides improved ride comfort to occupant/driver.

A mobile Ad hoc network (MANET) is a collection of wireless nodes that forms a network without central administration. The nodes in such kind of network serve as routers as well as hosts. The nodes can forward packets on behalf of other nodes and run user applications. The energy consumption of the nodes is a critical factor in the operation of a mobile ad hoc network. The existence of a node with low energy may degrade the performance of the system as the node participate in the route discovery phase, but due to low energy it does not forward the packet or it does not participate in message forwarding phase. Such type of node selection will degrade the system performance, minimizes the packet delivery ratio, and maximizes delay thus increasing energy consumption. So an important objective is to consider Energy Aware design of network protocols for Ad hoc network environment. The proposed scheme is incorporated with the route discovery phase of AODV and by simulation using NS/2 it is observed that the proposed algorithm is better than AODV in terms of packet delivery ratio and network lifetime.

In the present paper, the experimental pressure drop data measured for narrow sized silica sand slurry and bi-modal slurry which consists of narrow sized silica sand and fly ash as fine particles in different proportions, keeping the overall efflux concentration constant is used to generate the relative pressure drop characteristics to quantify the change in pressure drop characteristics. The pressure drop measurements are done using a pilot plant test loop over a straight length of 4.0 m in 50 mm NB diameter pipe line under fully developed flow condition. The flow velocities covered are in the range of 1.75 m/s to 4.0 m/s. The lowest velocity chosen is well above the deposition velocity. The pressure drop data collected for narrow-sized silica sand slurry and bi-modal slurry is at average efflux concentrations of 9.8, 20.4 and 33.9% (by weight). Based on relative pressure drop for bi-model slurry, study concludes that increasing the percentage of fine particles mixed in a narrow-sized slurry reduces the pressure drop significantly in the heterogeneous regime of slurry flows which are usually the operating range in prototype slurry pipelines.
