Abstract

In this project we have to apply the particle swarm optimization algorithm to job shop scheduling problem. Job shop scheduling is a combinatorial optimization problem where we have to arrange the jobs which may or may not be processed in every machine in a particular sequence and each machine has a different sequence of jobs. Job shop scheduling is a complex extended version of flow shop scheduling which is a problem where each job is processed through each and every machine and each machine has a same sequence of jobs. Our main objective in both kind of problem is to arrange the jobs in a sequence which gives minimum value of make span. PSO (Particle swarm optimization) helps us to find a combination of job sequence which has the least make span. In PSO a swarm of particles which have definite position and velocity for each job. In PSO, to find the combinations we use a heuristic rule called Smallest Position Value (SPV). According to smallest position value rule jobs are arranged in ascending order of their positions i.e. job having least position value is put first in sequence. In this project PSO is first applied to flow shop scheduling problem. This is done to understand how PSO algorithm can be applied to scheduling problem as flow shop scheduling problem is a simple problem. After Understanding the PSO algorithm, the algorithm is extended to apply in job shop scheduling problem for n jobs and m machines.

Abstract

In view of high energy potential in agricultural residues species and an increasing interest in their utilization for power generation an attempt has been made in this study to asses the proximate analysis and energy content of different components of four selected agricultural residues such as maize, coconut, paddy and arhar, and their impact on power generation and land requirement for energy plantations. The net energy content in coconut plant was found to be higher than other studied agricultural residues. The result shows that approximately 717 hectares, 1123 hectares, 1511 hectares and 4319 hectares of land are required to generate 20,000 kWh/day electricity from, coconut, maize, paddy and arhar pulse residues respectively. Coal samples, obtained from six different local mines were also examined for their qualities and the results were compared with those of studied biomass materials. This comparison reveals much higher power output with negligible emission of suspended particulate matter (spm) from biomass materials. It has been observed that coconut, paddy and arhar agricultural residue can be carried out safely (without clinker formation) up to the temperature of 950 o C.in case of use of maize agricultural residue, it may be more safe to operate the boiler at temperature below 800 o C. Since it has been observed that maize has lowest IDT (Initial deformation temperature) and lowest FT (Flow temperature), while coconut and paddy have highest IDT and FT.

Development of compact copper-stainless steel heat exchanger using diffusing bonding techniques


Dikshit, Vishwesh (2007) Development of compact copper-stainless steel heat exchanger using diffusing bonding techniques. MTech thesis.

Full text not available from this repository.

Abstract

The necessity of high effectiveness in a small volume has led to the development of perforated plate compact heat exchangers(CHE) for cryogenic applications. Although the basic principles have remained the same, the techniques of bonding have changed considerably during the last four decades. With the introduction of all metal construction, these exchangers are finding increasing use in cryogenic refrigerators. Besides soldering, brazing and adhesive bonding as joining techniques diffusion bonding of compact heat exchangers has been primarily applied. Diffusion bonding of copper to stainless steel(304) was carried out with interlayer metals such as Cr and Ni in order to investigate the influence of the interlayer metals on bonding conditions of the joints. The microstructure of the interfaces of diffusion-bonded bimetal was investigated by scanning electron microscopy(SEM) and X-ray diffraction (XRD). Solid state diffusion bonding technique is being applied in the construction of compact heat exchanger. In order to employ diffusion bonding processes for a construction of CHE, the process parameters which contribute to consistent formation of joints of the required strength have been critically examined. Process variables include temperature, pressure, time, surface roughness and, interlayer composition, density and thickness. Diffusion welding offers the unique possibility to achieve a metallurgical joining in the solid state without low melting filler, thus avoiding large brittle intermetallic phases, which form in the melt pool while cooling. The metals are joined by causing the coalescence of the metallic surfaces, by the application of pressure at elevated temperature for a finite interval. This technique produces joints with a minimum macroscopic deformation and without deterioration in the mechanical properties of the base metals, because the bonding is carried out below the solidus temperature(about 0.7Tin for the lowest melting-point metal) under a suitable pressure. Diffusion bonding of copper & SS were investigated to develop procedures for joining precision machined copper & SS components for the CHE. Diffusion bonds were tested over a range of temperatures from 800 0 C to 900 0 C, under different loading conditions(3 MPa-12 MPa ). The compact heat exchanger so fabricated has good strength, leak tightness and free flow of the heat-exchanging fluids.

Abstract

Material handling is undoubtedly the most important and in fact an indispensable job in industries for it is encountered at every stage right from the time raw materials enter the factory gate to the point when it leaves in form of finished products. The engineering of material handling falls under two categories depending on form of material: bulk solid handling and unit handling. In case of handling lumpy materials like coals etc. , feeder plays a vital role as an uninterrupted source of uniform feed provider to the conveyor system. Although several feeders like belt, apron, screw, feeders etc are available, reciprocating feeders are still in use because it ensures a continuous and controlled feed rate, is low in cost, its drive mechanism is simple, it can handle wide range of miscellaneous materials including lumps, easy in assembly and disassembly and maintenance requirement is quite low. The challenge which we have taken via the project, is to design a drive mechanism for a reciprocating coal feeder. We call it a challenge because we have to design various intricate components like couplings, worm reducers, gearbox etc. We call it complicated since all the components are interdependent on each other to a great extent. So we cannot design anything randomly . We have to take into considerations the smallest of small things like the various forces acting, how each component can fail under various stress conditions. We have to optimize everything right from the motor selection, to speed reduction ratio selection, to the capacity of coal which we can handle. We are going to follow the above-mentioned strategies so that our project does not remain just a theory but can become a reality for industries.

Abstract

An erosion tester is normally used to study the relative erosion behavior of different materials at moderate solid concentrations. Uniform distribution of solids and turbulence inside the container are generally the problems with the erosion tester and thus the data generated have limited application for quantitative analysis. In the present work, an existing mechanical stirrer has been converted into a slurry erosion tester by designing and fabricating a specimen holding arrangement for cylindrical and flat specimen by taking suitable dimensions according to experimental needs. Using this slurry erosion tester experiments can be carried out for investigating the wear characteristics of various materials which are subjected to slurry erosion. The machine has been tested by taking slurry of mud in a stainless steel container to find the rate of mass loss of an aluminium sample. This machine can be used for carrying out experiments on various samples of different materials which are subjected to slurry erosion by taking different types of slurries to find out the wear characteristics of the material by measuring the rate of mass loss with respect to various parameters like Slurry concentration, Speed of rotation, distance traversed and time.

Abstract

All electrical equipments generate heat through I2R loss within a specified volume resulting in temperature rise. The regulating bodies define the temperature rise limits for all equipments for safe operation. So during the design phase of any electrical equipment thermal analysis is mandatory to predict the temperature rise. The objective is to develop an analytical tool based on thermal networking method by exploiting the similarity between thermal and electrical analogy to calculate steady state temperatures in less time along current carrying path in electrical equipments. As a later part, the tool developed is used to predict change in temperatures for change in geometry of the components in the electrical equipment. The problem is considered as two parts. As first part, an Excel tool is developed with Visual Basic backend, based on thermal networking method to calculate steady state temperatures in electrical equipments. Here the numerical method used is Elementary Balance Method, in which every element is represented by a node and relevant energy balance equations are formulated for it. Temperatures are calculated using the Excel tool for frame 1 and 3. Test (Thermal Run) is conducted on AKD-12 switch gear (frame 1 and frame 3) under continuous current to find out temperatures. Analytical results from the tool are then validated against the test data. As second part, dimensions of components in the switch gear are varied and variation in temperatures of components, particularly at moving contact (highest temperature point) with respect to original temperatures is observed. Good matching is observed in temperature profile between analytical and experimental results. The maximum percentage error is 15%.By analyzing the results, it can be concluded that thermal network theory helps engineers to predict temperatures easily for changes in design reducing design cycle time and it is flexible as to expand its application to any heat generating equipment.

Detecting shift in a Weibull process using bootstrap method

[img]PDF

Abstract

Detecting a shift in a Weibull process is considered. The parametric bootstrap method is used to establish lower and upper control limits for monitoring percentiles. When process measurements have a weibull distribution small percentile is of importance when observing tensile strength and it is desirable to detect their downward shift. The performance of the proposed bootstrap percentile charts is considered based on computer simulations, and some comparison is made with the existing Weibull percentile chart. The advantage of the bootstrap method is that they are not restricted by assumptions on the distribution of the process measurements. The bootstrap method uses only the sample data to estimate the sampling distribution of the parameter estimator and then determine appropriate control limit. The new bootstrap chart indicates a shift in the process percentile substantially quicker than the previously existing chart, while maintaining comparable average run lengths when the process is in control.

Design of a pen which remembers what it writes

Abstract

Even in the current computer age, there are still many important application areas for a pen which remembers what it writes, such as early architectural design, entering letters in ideographic languages like Chinese- and Japanese; and non-letter entries like graphics, music and gestures ,and preparing a first draft of a document and concentrating on content creation where traditional tools like sketching on paper continue to be preferred by many professionals over computer-based tools. There is a growing awareness that there are often very good grounds for this preference. Hence, instead of trying to replace such traditional ways of working, it is now often considered more opportune to try and preserve the strengths of these traditional ways of working, while at the same time improving them by providing access to new media. This is one of the main objectives of the approach that we adopt here. In this project we have given the conceptual design of a digital pen which can remember what it writes based on optical tracking technology by integrating the various subsystems which are commercially available. A special type of paper is required to make this technology work. Printed on it is pattern consisting of millions of tiny dots, making it possible to identify the exact location of the pen tip. We have made a cost analysis for the fabrication of the pen based on the current market prices of the various components to be integrated and estimated the approximate dimensions of the pen.

Abstract

Red mud emerges as the major waste material during production of alumina from bauxite by the Bayer’s process. It comprises of oxides of iron, titanium, aluminum and silica along with some other minor constituents. Based on economics as well as environmental related issues, enormous efforts have been directed worldwide towards red mud management issues i.e. of utilization, storage and disposal. Different avenues of red mud utilization are more or less known but none of them have so far proved to be economically viable or commercially feasible. It is generally agreed that resistance to wear of MMCs is created by reinforcement and also the wear properties are improved remarkably by introducing hard intermetallic compound into the aluminium matrix. The reinforcing materials are generally SiC, Al2O3, TiB2 etc and are costly. The present research work has been undertaken with an objective to explore the use of red mud as a reinforcing material as a low cost option. This is due to...
