In this paper, we propose a simulation model of electromagnetic wave’s propagation, in media with different kinds of dispersions. This approach is based on the existing Auxiliary Differential Equation (ADE) technique in the context of the Transmission Line Matrix method with the symmetrical condensed node (SCN -TLM) and novel voltage sources. The proposed model, named ADE-TLM, gives a full solution of Maxwell’s equations and polarisation terms which describe the Lorentz linear dispersion, the nonlinear instantaneous Kerr and retarded Raman effects.

The potential for solar energy as a sustainable source of energy is well understood. With the ever increasing use of solar power the necessity of a model is accentuated. This paper focuses on a MATLAB/Simulink model of a photovoltaic module. It presents the implementation of a generalized photovoltaic model, which can be representative of PV cell, module or array, in order to estimate the electrical behavior of the module with respect to change in environmental parameter i.e. Insolation keeping the cell temperature constant. This model is based on mathematical equations and is described through an equivalent circuit including a photocurrent source, a diode, a series resistor and a shunt resistor. Taking the effect of sunlight irradiance as variable parameter into consideration, the output current and power characteristics of PV model are simulated This enables the dynamics of PV system to be easily simulated, analyzed and optimized. The essential parameters required for modeling the system are taken from datasheets. A particular typical 60W solar panel is used for developed model evaluation and simulation results are compared with points taken directly from the manufacturer’s published curves and show excellent correspondence to the model.

The orientation towards an efficient mass customization confronts most companies with two opposing requirements: While the applied mass production system should be able to produce a huge product variety, the cost must be kept low. Therefore assembly lines have to be planned in a much more flexible way. The more complex the product, the more extensive the product mix—the more difficult the task. Shorter product life cycles also complicate the situation. Due to the volatile nature of market, companies cannot afford to manufacture same type of product for long period of time and neither can maintain high inventory level; to tackle this problem we propose a Continuous improvement tools and techniques are introduced to address these issues, allowing the manufacturing of superior quality products with efficient processes. The Lean tools and techniques is one of them.

Di-octyl phthalate (DOP), synthesized by esterification of phthalic anhydride (PAN) with 2-ethylhexanol (2EH), is widely used plasticizer. DOP is industrially manufactured using acidic homogeneous and heterogeneous catalysts such as para-toluene sulphonic acid (p-TSA), methane sulphonic acid, tetra butyl titanate (TBT), titanic peroxide, superacidic zirconia, etc. One of the major problems in the manufacture of DOP is discolorization of product particularly with increasing catalyst concentration and temperature. Therefore, in the present investigation attempt has been made for decolorization of DOP using activated carbon (AC). The effect of the various operating parameters such as concentration of adsorbent, temperature, and time has been systematically investigated. It has been found that AC could be used for decolorization of DOP effectively.

Large amounts of lignocellulosic waste are generated through forestry and agricultural practices, paper-pulp industries, timber industries, and many agro industries. They pose an environmental pollution problem. One of the most economically viable processes for the conversion of lignocellulosic wastes into useful products is the use of earthworms. This process by which earthworms are used to convert organic materials is known as vermicomposting. In the present study, vermibeds were prepared by mixing the pre-treated chip wash residue (CWR), a wood waste obtained from wet process hardboard factory, with fresh cow dung slurry in different proportions viz., 50:50, 60:40 and 70:30. Simultaneously, a control for each of these concentrations was prepared and maintained. Ten Eudrilus eugeniae adult earthworms were introduced into each of the trays excepting the control. The highest conversion ratio i.e., waste into vermicompost (52%) was observed in 60:40 proportion than the other. Besides, the mean number of cocoons, young ones and quantity of chemical nutrients observed in 60:40 concentrations was high when compared to 50:50 concentrations. The results of this study obviously suggest that the wood waste with cow dung at 60:40 concentrations can very well be used for converting into value added vermicompost by utilizing E. eugeniae.

Liquefied petroleum Gas (LPG) cylinders undergo various tests before they certified by Bureau of Indian Standards for market use. Acceptance test is one among those tests, in which the cylinder mechanical properties of parent metal are checked against specification for compliance. Acceptance test is a destructive test, in which tensile samples are carefully drawn from LPG cylinder in both longitudinal and circumferential directions and tested on a tensile testing machine to measure Tensile strength, Yield stress and Percentage Elongation. These resulted mechanical properties depend on several factors such as raw material selection, manufacturing process, heat treatment process parameters. An attempt has been made in this paper to study and understand correlations among these properties.

In order to address the environmental issues associated with the production of the Portland cement, there is an urgent need to develop alternative binders to make concrete which can prove economical and environmental friendly. Geopolymer concrete, which does not utilize Portland cement but is made by using materials, rich in silicon and aluminium such as fly ash can to be an alternative in this direction. In Geopolymer concrete, fly ash reacts with alkaline liquid comprising of a mixture of sodium silicate and sodium hydroxide solution to form the binder. Another environmental issue is the disposal of plastic waste. This study focuses on the use of polymer plastic as concrete constituent in Geopolymer concrete. The experimental work were conducted on fly ash based geopolymer concrete by varying the sodium silicate to sodium hydroxide ratio, molarity of sodium hydroxide and percentage of metallized polymer plastic waste. Geopolymer concrete was hot cured at 1000Cfor 24 hours in hot air oven. The compressive strength, split tensile strength and pull-off strength of Geopolymer was determined. The experimental result shows that the strength properties of Geopolymer concrete containing metalized polymer plastic is in the order of strength properties of conventional cement concrete.

In India more than 115 million motor vehicles are registered at the end of the year 2010-11, almost all driven by Internal Combustion engines. These vehicles emit large quantity of pollutants e.g. Carbon Monoxide, Unburnt Hydrocarbons etc which are responsible for more than 20% of the air pollution. The studies show that the internal combustion engines of motorcycles may generate up to two times more pollutants than those of motorcars. In order to reduce the air pollution and eliminate the pollutants from exhaust this project presents a new idea of using compressed air as power sources for motorcycles. The electricity requirement for compressing air has to be considered while computing overall efficiency.
It seems that commercial 4 strokes bikes can be run on compressed air by very few modifications. Also a new bike can be design especially for compressed air. Early cost analysis shows that modified engine runs with much less cost. The operational cost is ten times less than that of petrol or diesel. Experimental analysis was carried out on this modified engine and its performance characteristics like brake power, indicated power etc are analyzed. After successions on the experimental set up performance was checked on the workshop floor. It was found that engine can start and run very smoothly on compressed air with good speed was achieved. Nevertheless, as Main advantage of this engine is that no hydrocarbon fuel required means no combustion process is taken place; the compressed air vehicle will play important role to reduce air pollution

Composite materials are widely used in various applications such as automobile industries, aircraft, marine etc. Composites are made up of individual materials referred to as constituent materials. The constituents are combined on a macroscopic scale and are insoluble to each other. Generally, a composite material is composed of reinforcement (fibers, particles, flakes, and/or fillers) embedded in a matrix (polymers, metals, or ceramics). The matrix holds the reinforcement to form the desired shape while the reinforcement improves the overall mechanical properties of the matrix. When designed properly, the new combined material exhibits better strength than that of each individual material. Composites offer several other advantages over conventional materials. These include improved strength, stiffness, fatigue and impact resistance, thermal conductivity, corrosion resistance, etc. In this paper the work is carried out on carbon FRC laminate with elliptical cut out by varying major minor axis dimensions for stress analysis using reflection polariscope as a photoelasticity technique.

Load forecasting is the technique for prediction of electrical load. In a deregulated market it is much need for a generating company to know about the market load demand for generating near to accurate power. If the generation is not sufficient to fulfil the demand, there would be problem of irregular supply and in case of excess generation the generating company will have to bear the loss. Neural network techniques have been recently suggested for short-term load forecasting by a large number of researchers. This work studies the applicability of this kind of models. The work is intended to be a basis for a real forecasting application. First, a literature survey was conducted on the subject. Most of the reported models are based on the so-called Multilayer Perceptron (MLP) network. There are numerous model suggestions, but the large variation and lack of comparisons make it difficult to directly apply proposed methods. It was concluded that a comparative study of different model types seems necessary. Back propagation in neural network is used to train neural network. Various techniques are used in BPP analysis. In this paper mean square error (MSE) is considered as performance criteria and various BPP methods are analysed on MSE criteria.

The present research deals with the probability of the failure rate of a thermal plant using the Boolean algebra. These opportunities will be identified by evaluation of a power generation system of a thermal power plant. This feasibility study covers two areas: development of a mathematical model and evaluation of performance with the help of the developed model. It assumes two states either working or not working. Failure and repair rates of all subsystems are assumed to be constant. On the basis of this study, the performance of a power generation system is evaluated. The developed model helps in the comparative evaluation of alternative maintenance strategies. The techniques used earlier to solve such reliability models are very time consuming and with very tedious calculations. Therefore, in this study the authors are using Boolean function technique and algebra to logics to evaluate system’s overall performance. Reliability of considered system has been computed, in case, failures follow Weibull and Exponential time distributions. An important reliability parameter namely, M.T.T.F. of considered system has also been evaluated to improve practical utility of the model.

A conventional differential that is non-locked differential always supplies close to equal torque to each side. With an automotive differential if one wheel is held stationary, the counterpart wheel turns at twice its normal speed. A differential locking system introduced here can be engaged or disengaged either manually or automatically, as per the conditions or a sensor based system can be developed that will sense the difference in speed or stalling of one wheel to lock the differential by sliding a dog ring to get engaged in planetary gear spike shaft so that both wheels will have same traction. If the difference in the speed of driven and rolling wheels is encountered then the differential is controlled to lock.

In this study, an attempt has been conducted to investigate the effects of cutting parameters on tool wear and surface roughness during hard turning of Inconel 718 material. By taking into account the Analysis of Variance (ANOVA) in accordance to Central Composite Design (CCD); the mathematical model of the flank wear and surface roughness are developed with transformation of the natural logarithm. The experimental results have revealed that the cutting speed is the most significant effect to the flank wear; whereas the surface roughness is strongly influenced by the feed rate and slight related to the tool wear mechanisms. Due to the high pressure at elevated temperature, a micro-welding and built-up-edge are formed even at relatively low cutting speeds of 30-45m/min; it is a disadvantage for the machined surface quality. In particular, the surface roughness tends to decreased with the increased of the cutting speed when the built-up-edge was disappeared. However, the tool wear increased rapidly when the cutting speed increased over 90 m/min. This phenomenon is therefore inevitable affected to the tool life and the machined surface quality.
