A production practice that aims to minimize shop floor inventory and maintenance related losses in a Lean Developed production model. To achieve as close to minimum inventories means stockless production, with minimum maintenance losses. As possible its origins extending deep into developed works on tight material control policies. By eliminating the costs of storage and capital tied up in inventory it is possible to eliminate seven wastages like zero defects, setup time, breakdowns, handling, lead time and surging. Goals of Lean production is, all the efforts directed for achieving zero inventory by producing the components or assembly parts when exactly it needed, and such tight scheduling is possible only by an efficient maintenance system . This thesis introduces the development of Lean based maintenance system and their immediate effects on the productivity of industry. In an exploring automobile industry many techniques are invented and implemented to discover to know how an automobile manufacturer can bring down his costs, using the advance production management theories, in their existing processes. This research work discusses the combined issues and solution of lean thinking and maintenance in a way to improve performance indicators. The impacts of lean thinking focus maintenance in an organization. The need of maintenance to align itself with the business objectives in relevant of any organization performance measures are important inputs to improvement the productivity of organization, and maintenance in particular, through lean tools and activities.

The objective of the proposed research work is to investigate the use of self resonating coils operating in a strongly coupled mode for wireless power transfer applications, study and optimize the results of using coils of different geometries on power transfer efficiency and demonstrate the concept by transferring power wirelessly. Using the theoretical analysis, derived equations and simulations, a structure made of cylindrical coils with source radius 7.5cm capable of delivering wireless output power up to 4 watts at an efficiency of 70% wirelessly over 10cm was built. A further increase in efficiency of about 8% was achieved by using a combination of a cylindrical source and spiral receiver which also has the significant advantage of being easier to implement in future applications due to sizeable reduction in volume required on the receiving side. Finally the wireless power transfer was also given a physical dimension by demonstrating the lighting of bulbs at 20cm at an efficiency of 51% and the wireless charging of an i-pod was attempted.

The main objective of the present work is to analyze the pressure compensation phenomenon and observe the variations in output flow as per change in pressure margins across the directional flow control valve. A MATLAB code is created and Simulink model is built for dynamic analysis of capturing compensator spool behavior in typical pre-compensated mobile control valve. Simulation results are compared with the test results and correlation is established.

Liposomes are the class of drug delivery systems which are considered as biodegradable, biocompatible, flexible, non-ionic and non-toxic and provides direct interaction of the drug with cell and can modulate the distribution of drug and also increase the therapeutic index of drugs. It can also be modified and used to deliver genes and protect some sensitive tissues to a particular kind of drugs. Manufacturing of liposomes requires use of expensive raw material (synthetic phospholipids) from specialized commercial suppliers makes the liposomal based drugs very expensive due to complex extraction procedure which time taking and products obtained in a very less amount. In this research work extraction of phospholipid of E.coli bacteria was done by solvent extraction procedure and characterized by paper chromatographic, spectroscopic techniques like UV- Visible, Photoluminescence, FTIR and dynamic light scattering techniques, particle size analyzer and zeta potential. It has been found that phospholipid so obtained has same properties as that of synthetic phospholipids and it can be an alternative to synthetic phospholipids to reduce the cost of the drug delivery systems. Such methods are ecofriendly, less time consuming and an abundant amount of product is obtained for the development of liposomes.

Disperse dyes are largest group of dye used for dyeing of polyester, nylon and cellulose triacetate. The waste water generated during dyeing process contains dyes and other chemical auxiliaries which are major environment concern due to their toxic and carcinogenic impact. These paper reviewed different technique available for disperse dye removal from textile effluent.
