Machinery diagnostics is used for predicting existing defects and used to prevent catastrophic failures in mechanical systems. During operation, the mechanical parts are subjected to heavy and dynamic loads generated by machines and transmitted through the components of rolling element bearings. There are different methods for the diagnosis of these defects in the bearings viz. acoustic measurement, temperature monitoring, wear debris analysis and vibration measurement. A combination of these techniques can predict an upcoming failure with a certain level of confidence and accuracy. The main aim of our project is to design a machine that enables finding out potential defects in a machinery and be able to predict the remaining life of components. Diagnosing wearing parts of machines and engines.........

Potter‟s wheel is increasingly being recognized as highly sustainable for making clay or earthen pot. Unfortunately, the traditional pottery making industry is on the verge of extinction. There is a growing concern to revive this dying industry. Different processes and techniques used in pottery making are understood by carrying surveys and field visits. The electric potter‟s wheel is used in rural areas as an alternative to human powered potter‟s wheel, but it is economically not feasible. The author introduces a conceptual model to minimize the efforts and overcome problems in pottery makings. The present work deals with design and development of human powered potter‟s wheel, providing a solution to cater economic, ergonomically and operational problems. Sewing machine pedal mechanism has many low powered applications, which can be used to minimize human efforts and increase efficiency. The proposed design enable researchers to provide economical and user friendly potter‟s wheel, which rotates efficiently utilizing the mechanical energy of the sewing machine pedal.

Metal matrix composites are one of the newly developed engineered materials of considerable interest. Metal matrix composite consists of at least two constituent parts, of which one constituent part being a metal and the other part may be a different metal or another material, such as ceramic or organic compound. These materials are known as the difficult-to-machine materials because of the hardness and abrasive nature of reinforcement element like silicon carbide (SiC). Hence, they imposemach inability related challenge, to conventional machining process such as turning, milling etc. Electrical discharge machining (EDM) is a non- conventional process becoming a popular choice for machining these materials. In view of this, the present work is aimed at investigating the effect of tool shape and size factor on material removal rate during electrical discharge machining of aluminiumbased metal matrix composites, in conjunction with the variation.......

An experimental setup has been developed for theverification of newtons law viscocity. This experiment confirms direct proportionality between shear stress and the rate of shear strain. Different fluids with known value of viscocity such as glycerien, honey, water, engine oil etc were tested for charecterization.Results shown that honey shows the non newtonian behaviour and glycerian and unburnt engine oil shows the newtonian behaviour. Fluid mechanics is the study of fluids either in motion or at rest for both liquids and gases. There is a theory available for fluid flow problems and it should be backed up by experiment. As there are the various experimental setup for verifying the different laws in fluid mechanics, but there is no setup to verify Newton's law of viscosity. Here we propose the experimental setup for verification of Newton's law of Viscosity.

Crankshaft oil hole drilling process is one of the important step in crankshaft manufacturing process. Drill bit failure or breakage is one of the sensational issues in crankshaft oil hole drilling process. It can be minimized by controlling some input parameters. With minimization of drill breakage, productivity also should be maintained. Therefore it is necessary to optimized drilling parameters to improve drill bit life and productivity as well. This paper review the research work completed by previous researcher in optimizing drilling parameters. In past, researcher has been used the conventional multi objective optimization methods, but each methods has its limitations. From review of these papers it is observed that MOORA and TOPSIS are effective methods among other multi objective optimization methods.

Increased environmental awareness regarding impact of green house gas emissions and CFCs lead into search of environmentally friendly cooling technologies for buildings which consume minimum or no energy. This paper reviews various passive cooling techniques by using Phase change materials. Passive cooling techniques are closely linked to the thermal comfort of the occupants, and it is possible to achieve this comfort by reducing the heat gains, thermal moderation and removing the internal heat. In the paper, various methods adopted under these techniques and information regarding Phase Change materials and their desirable properties are reviewed.

Additive Manufacturing is an advanced manufacturing process which is not only cost efficient, but is also completely customizable. With the aid of CAD/CAM and 3D printing technology in Biomedical Science, variety of organs can be generated. Bone being structurally strong and porous, scaffolds with approximate porosity can be made using 3D Printing technology. As accidents are on a rise, the demand for organs is also increasing. To tackle the problem, 3D printing of Biomaterials can be taken into account, following which numerous patients can be treated and relieved. While there are synthetic as well as natural polymers for printing, the choice of the material is made according to the location and type of fracture.

Food and Municipal waste is the single largest component of the waste stream by weight. These organic wastes needs to be managed in a sustainable way to avoid depletion of natural resources, minimize risk to human health, reduce environmental burdens and maintain an overall balance in the ecosystem. Anaerobic digestion is a promising technology which could effectively address the problem of waste disposal yielding valuable outputs like biogas and fertilizers. Anaerobic digestion of a mix of food, Cow dung, and Municipal waste and Mix wastes has been carried out in a 20-liter digester within 14 weeks. The wastes were an aerobically digested in an anaerobic digester at ambient temperature. The objective of this paper was to study the performance of the anaerobic process used food, Cow manure, Municipal waste and Mix wastes as substrates in a four digester for biogas production.........

Emerging demand for producing complex shapes on variable materials gives rise to the need for an alternative to the conventional forming process. Incremental forming is a new technique for deforming sheet metals by the application of step-by-step incremental feed to a deforming tool (DT). In this study, commercially pure Titanium sheets were used in incremental forming with an aim to investigate the influences of process parameters such as feed rate, tool diameter, and pitch on the forming of these alloys. By using the Taguchi Method L9 array were finalized for experimentation. Incremental forming was carried out on constant thick pure Titanium sheets in a CNC vertical milling machine. The process was done using a hemispherical shaped tool made of high-speed steel. Optimization of incremental process parameters with the aid of Grey Relational analysis has also been carried out to identify the combinations of the parameters that yield better surface characteristics on the formed sheets...........
