ABSTRACT
The reduction of friction and wear is critical to the proper functioning of modern machines. A more complex machine has a stricter lubrication requirement. Machine components and mechanism pairs depend on high-quality lubricants to enable withstanding high temperatures and extreme pressure (EP). Extreme pressure and antiwar (AW) additives are typically adopted to improve the Tribological performance of a fluid lubricant in reducing friction and surface damage under severe conditions. Nanoparticles have attracted considerable interest in recent years because of their excellent physical and chemical properties. However, inorganic nano particles very easily agglomerate in many media and have poor dispersive capacity in organic solvents and oil. Therefore, the applications of many Nanoparticles are quite limited. However, the dispersion problem can be solved using some physical and chemical approaches. The Tribological properties of Nanoparticles used a soil additives have been recently investigated.

ABSTRACT
This paper reports on an optimization of procurement process parameters for modern construction material DOE (Taguchi method) to improve the quality of procurement goods and engineering development of designs for studying variation. There are three procurement parameters i.e. Cost, Quality, Time are considered. Different experiments are done by varying one parameter and keeping other two fixed. Taguchi orthogonal array is designed with three levels of procurement parameters with the help of software Minitab 15. Taguchi method stresses the importance of studying the response variation using the signal–to–noise (S/N) ratio, resulting in minimization of quality characteristic variation due to uncontrollable parameter. The procurement process was considered as the quality characteristic with the concept of "the smaller-the-best". The S/N ratio for the smaller-the-better where n = -10 Log10 [mean of sum of squares of {measured -ideal}] and y is the measured value in a run/row. The S/N ratio values are calculated by taking into consideration with the help of software Minitab 15. The values measured from the experiments and their optimum value for reducing total cost of material. It is also predicted that Taguchi method is a good method for optimization of various procurement process parameters as it reduces the number of experiments. From the literature survey, it can be seen that there seems to be little work done on procurement of construction material. So in this project the procurement is done in order to optimize the procurement process parameters for reducing the total cost of project

ABSTRACT
Day to day automated energy control has become a standard practice. All dwellings, residential, commercial or industrial use energy. This energy is used to maintain creature comforts such as heating and cooling, water heating, lighting, and other tasks such as running appliances, machines, or other equipment. Because this demand can be 24 hours a day, 7 days a week, any methodologies to conserve energy will result in a reduction in energy costs. Virtually all nonresidential buildings have automatic controllers with a computer as the central processor. These systems are called Energy Management Systems (EMS), Energy Management Control Systems (EMCS), or Building Automation Systems (BAS). Today’s building owners and facility managers must regularly address the issue of computerized energy management-assessing existing systems, specifying and commissioning new systems, evaluating service contract options, or optimizing EMS operations.

ABSTRACT
Supplier selection and evaluation are arguably one of the most critical functions for the success of an organization. These decisions are complicated because potential options need to be evaluated on more than one criterion. Purchasing managers need to evaluate periodically supplier performance in order to retain those suppliers who meet their requirements in terms of several performance criteria. The evaluation element typically consists of identifying the attributes or factors that are relevant to the decision and then measuring or rating each supplier by considering each of the relevant factors. The present paper deals with the problem of supplier selection through application of fuzzy based multi-objective optimization on the basis of ratio analysis (MOORA). We take a real-world problem of supplier selection for chemical and biotechnology organizations in India to illustrate the use of proposed methods. We have found the proposed system so simplified that the engineers/managers of the related fields will find implementation of this technique very easy and suitable.

ABSTRACT
Among the industrial activities sand casting process still remains as one of the most complex and indefinite activities. Due to the complex relationship between casting defects and green sand properties, it is imperative to control many green sand characteristics that influence casting quality. Traditional method of trial-and-error based on know-how and experience has many disadvantages such as being nonsystematic, time consuming, error-prone and requirement for long durations of experimentation. There is a necessity to replace this traditional approach to produce higher quality casting products within reasonable periods of time making better use of statistics, artificial intelligence knowledge acquisition neural networks and data mining tools. This paper extensively reviews published research on green sand casting process. The effects of riser design, gating system, moulding sand, oxidation and deformation of casting during heat treatment, machining allowance, etc., on the economical manufacture quality castings were reviewed. Determining the optimal process parameter setting will significantly improve the mould yield, output ratio of metal, shorten manufacturing period, save energy and resource, reduce pollution, and improve the competitiveness of enterprises.

ABSTRACT
Due to the increasing demand for fossil fuels and environmental threat, a number of renewable sources of energy have been studied worldwide. This paper represents an experimental investigation of constant speed single cylinder vertical air cooled DI biogas premixed charge diesel dual fuelled compression ignition engine used in agricultural application and water pumping application in rural areas. The engine performance, diesel substitution and energy consumption have been studied. The investigated results show that biogas-diesel dual fuel engine works with lower energy conversion efficiency which was offset by the reduced fuel cost of biogas over diesel. Biogas premixed charge diesel engine emits less amount of smoke but emits more amount of CO and HC. The long term use of this engine with biogas-diesel dual fuelling mode is feasible for agricultural field and water pumping in rural area.

ABSTRACT
A conventional method of designing power line filter using a unique combination of constant- k and m-derived composite section has been introduced. The Composite Low pass filter is implemented in the classical design technique of power line filter. The filter is used for the attenuation of Conducted emission (CE) that is usually generated due to the frequent load switching. To maintain the accuracy of the design, a separate set of filters are designed f or both the Common mode (CM) and the Differential mode (DM) of the filter. And the final design of the filter is designed by using the Cascaded structure of the CM and DM section of the filter in an Equivalent Circuit. The entire Equivalent circuit is further analyzed using the two-port Network parameters. The Transmission parameters are used in Network analysis of the Equivalent Circuit. Finally, the design of the filter circuit is Simulated using Advanced Design software (ADS) based on S-parameters, to see the basic filter characteristics. A minute tuning in the circuit lumped components is applied, in order to meet the practical specifications. A comparison on the Filter response, before and after tuning, of the components in the design, is presented in the last section of the paper.

ABSTRACT
An image may be defined as a two-dimensional function, f(x, y), where x and y are spatial (plane) coordinates, and the amplitude of f at any pair coordinates (x, y) is called the intensity or gray level of the image at that point [2][4]. When (x, y) and the amplitude values of f are all finite, discrete quantities, we call the image a digital image.In this paper a proposed approach is defined and it is compared with different approaches of image de-noising. The proposed approach shows the best results as compare to the existing approaches.

ABSTRACT
Pre-stressed Concrete is very useful now a days. It has less shrinkage, less creep and reduced deflection due to dead and live load. Material properties are improved in Pre-stressed concrete. Also total construction time is also less in case of pre-stressed concrete. One of the major properties of concrete that makes pre-casting economically feasible is its ability, under the proper conditions, to gain compressive strength extremely rapidly. In this paper, various methods to increase the curing rate for precast concrete are discussed. Different methods for accelerating the curing process are: 1) the use of physical processes, and 2) the use of admixtures to act as catalysts for the hydration process, resulting in the achievement of high compressive strengths in relatively short periods of time. Many physical processes used to increase the curing process are generally obtained by increases in curing temperature, introduction of moisture to curing environment. Numerous methods exist, including conductive/convective heating, electrical resistance heating, and steam curing (low and high pressure).
