Nathan, Senthil   (2011)   Service Quality in Power Sector.   BTech thesis. PDF 1972Kb Abstract Service quality is an important issue in the electricity distribution and retail sectors. Customers are highly sensitive to all aspects of service quality and value the speed and accuracy with which their requests are handled, the reliability of the electricity supply, and the characteristics of the supply voltage. Quality regulation entails complications and subtleties. First of all, there is the multi-dimensional nature of service quality. Furthermore, the ideal level of quality depends on consumer preferences, and these preferences can vary widely among customers. In addition, measuring quality can be difficult, consumer behavior can affect the quality of the network, and so forth. As a result, there is no simple policy indication for service quality regulation: different means are normally used to induce regulated companies to deliver the desired levels of service quality on different qualit

Nayak, Sarthak   (2011)   Study of chip breaker on turning of stainless steel.   BTech thesis. PDF 1045Kb Abstract Machining of metals is the most universal and major stage of manufacturing system. It involves forcing of the cutting tool through the excess material of the work-piece, thereby rendering work-piece to a desired shape and size. So in present modern technology processes, optimization of machining parameters is one of the key necessities. For the case of turning operation, unbroken chips pose a major obstacle for maintaining accurate machining processes. The continuous chip generated during turning operation deteriorates the work-piece precision and causes safety hazards for the operator. Effective chip control is necessary for automatic production system because any failure in chip control can cause the lowering in productivity and the worsening in operation due to frequent stop. Chip control in turning is difficult in the case of stainless steel because chips are continuou

Mohapatra, Chinmoy Krushna   (2011)   Computer aided analysis of balancing of multi cylinder radial and v- engines.   BTech thesis. PDF (Btech Thesis) 2659Kb Abstract The reciprocating engines are the prime source of power generation in various mechanical applications ranging from power generation to automobiles. Noise, vibrations and harshness are caused in this engine due to unbalanced inertia forces and moments which further cause complications in their operation. To minimise the unbalance, analysis for the unbalanced forces and moments for different configuration of cylinders and firing order of multi-cylinder radial and V engines are done. The C programs have been developed for this analysis to minimise the time and calculations. The radial, V engines and combined radial and inline configured engines are compared on the basis of resultant unbalanced forces and moments. Item Type: Thesis (BTech) Uncontrolled Keywords: balancing, radial engines, vee engines, computer programme Subje

Mondal, Arpan Kumar   (2011)   An investigation on characterization of bio-composites.   MTech thesis. PDF 5Mb Abstract This research work describes the characterization and fabrication of bio-composites as artificial bone implant materials. The fractured bone can be repaired or replaced by artificial bone materials. Many implant materials has been made in the last three decades made of metals alloys ceramics polymers etc. The main problem with the metallic bone implants is the stress shielding and bone regeneration. Polymeric bone implants may overcome these difficulties. This article presents the processing techniques and experimental results of two different bio-composites viz. Hydroxyapatite (HAp)/High density polyethylene (HDPE) bio-composite by micro-injection molding and compression molding technology and Hydroxyapatite (HAp)/High molecular high density polyethylene (HMHDPE) bio-composite by compression molding technology. The initial materials HAp was synthesized by wet chemica

Mishra, Punyapriya   (2011)   Development and Characterization of Low Cost Composite from Sugarcane Bagasse Waste. PhD thesis. PDF 28Mb Abstract Environmental awareness today motivates the researchers, worldwide on the studies of natural fiber reinforced polymer composite and cost effective option to synthetic fiber reinforced composites. The availability of natural fibers and ease of manufacturing have tempted researchers to try locally available inexpensive fibers and to study their feasibility of reinforcement purposes and to what extent they satisfy the required specifications of good reinforced polymer composite for different applications. With low cost and high specific mechanical properties, natural fiber represents a good renewable and biodegradable alternative to the most common synthetic reinforcement, i.e. glass fiber. Despite the interest and environmental appeal of natural fibers, there use is limited to non- bearing applications, due to their lower strength compared with

Mishra, Tanmaya   (2011)   Machine Loading in Flexible Manufacturing system using Artificial Immune algorithm.   BTech thesis. PDF 1214Kb Abstract In this project thesis the FMS loading problem is discussed with the objective to minimize the system unbalance and throughput by the use of Artificial Immune system. Manufacturing technology focuses primarily on flexibility and productivity. With the product variety and product life being the characterizing standards it is important that the flexibility of the job shop is maintained as its efficiency is increases. The complexity of a basic Machine loading problem in FMS is very high due to the different flexibility criteria as Part selection, Operation allocation and the various constraints involved. This dissertation proposes a soft computing technique with constraints on tool capacity and workload of the machine. The aim of using this algorithm is to reach an optimal solution and to ease the tedious computations in large problems involvin

Mohanty, Chiranjiv   (2011)   Experimental investigation of the combustion, performance and emission parameters of a compression ignition engine using blends of vegetable oil and diesel fuel.   BTech thesis. PDF (B.Tech 107me039) Restricted to Repository staff only 1439Kb Abstract Rapid depletion petroleum reserves, gradual rise in the oil prices and the wide-spread pollution caused by these fuels have led to a great concern worldwide to develop better and cleaner strategies. This global concern has promoted research to find substitutes to fossil fuels with considerable efficiency and lower emissions to cater with the stricter emission norms as set by various governments. Diesel engines are well established today, as the main power train solution for trucks and other relevant heavy duty vehicles. Thus, developing substitutes to diesel for efficient and clean application in these diesel engines is the need of the day. Vegetable oils are very good alternative fuels and have great potenti
