The growing demand in today’s competitive manufacturing environment has encouraged the researchers to develop and apply modelling tools. The development and application of modelling tools help the casting industries to considerably increase productivity and casting quality. Till date there is no universal standard available to model and optimize any of the manufacturing processes. However the present work discusses the advantages and limitations of some conventional and non-conventional modelling tools applied for various casting processes. In addition the research effort made by various authors till date in modelling and optimization of the squeeze casting process has been reported. Furthermore the necessary steps for prediction and optimization are high lightened by identifying the trends in the literature. Ultimately this research paper explores the scope for future research in online control of the process by automatically adjusting the squeeze cast process parameters through reverse prediction by utilizing the soft computing tools namely, Neural Network, Genetic Algorithms, Fuzzy-logic Controllers and their different combinations. The present work also proposed a detailed methodology, starting from the selection of process variables till the best process variable combinations for extreme values of the outputs responsible for better product quality using experimental, prediction and optimization methodology.

A helmet is a protective layer that is worn in order to prevent head injury. Helmet is the most important safety gear for two wheeler riders. But due to carelessness of people and paying less importance toward safety, there are a lot of causalities every year. Especially in countries like India these accidents are common due to ignorance toward safety. According to National Crime Records Bureau (NCRB) two wheelers claimed 92 lives every day out of which most were due to helmetless drive. Many seminars and road safety campaign were organized but still there is very less improvement. The most people who met accident were youngsters. So In order to overcome this problem we came up with the idea of SMART HELMET. The smart helmet will help to reduce the injuries to head. The smart helmet will be different in many ways. It will be technically advanced and electronically controlled. The system design will be such that without wearing the helmet the rider cannot start two wheelers. The helmet will be connected to vehicle key ignition systems which will be electronically controlled. The smart helmet will be having proximity sensor fitted inside it, which will act as our switch for on/off ignition and further with wireless connection the helmet sensor circuit will be connected to the vehicle ignition system. If the rider is wearing the helmet he will be able to crank the engine and could propel, where as in case if helmet is not there then vehicle will cannot start. This will surely reduce the no of fatalities on road and hence giving a safer drive.

The engine ecological indicators should be controlled during certain period of engine running. Maintaining intended level of the exhaust emissions from diesel engine during certain running, requires, first of all, high stability of the engine working process, and secondly, organization of suitable operative control of the engine over pre-defined le-vels of different ecological indicators. The measurement of concentration of harmful gaseous substances (HGS) within a stream of the exhaust gases does not present difficulty in connection with portable gas analyzers, but measurement of particulate matters (Ð Ð) under operating conditions is impossible. In this work, a modeling method based on indirect measurable indicators to determine the concentration of engine particulate matters and their main composition is described. This method accounts the dependency of PM from en-gine on the heavy hydrocarbons as well as provides different sources of these heavy hydrocarbons. The results ob-tained from the current modeling method are presented and considered in this paper.

One of the main problems to be considered in an electric vehicle is the way to maintain a good climate conditions in order to ensure a thermal comfort in the passenger compartment to provide an optimum performance of the batteries. In this paper, the influence of the electric air-conditioning system on the power consumption of a Lithium-ion battery was studied. The model of the air conditioning system was developed based on the thermal loads variations caused by the external temperature. In order to optimize the autonomous efficiency of the batteries, a thermal management system must be installed. The model was coded on the Matlab/Simulink platform and simulated.

In this work, a preliminary lay out of hybrid fuel cell-battery vehicle is developed and a 2012 GEM eL Golf car is evaluated and designed for analogous vehicle requirements. Packaging of electrified powertrain modules have been assessed and proposed. Further, the conceptual design is simulated as a series hybrid PEM fuel cell-Li-ion battery vehicle model in Powertrain System Analysis Toolkit (PSAT®) software. The output performance of the vehicle with the proposed electrified powertrain components is obtained, analyzed and the results are deemed satisfactory and in par with the performance of the conventional vehicle.

Many control systems encountered in physical, automobile engineering, economic phenomena and biomedical engineering fields are nonlinear and nonstationary to some extent. In general, nonlinear processes can be adequately characterized by a nonlinear model. Recently, a system can be obtained directly from experimental input/ output data by determining the system structure and the numerical values of the unknown parameters, this process is known as system identification. System identification techniques for linear and nonlinear systems have received such attention and have been widely applied to reveal fundamental properties of the system which are not apparent. Billings [1] surveyed the available approaches of non-linear system identification by considering the functional series of Volterra and Wiener, and the identification algorithms developed by Ku and Wolf [2]. Narendra and Parthasarathy [3] considered the orthogonal expansion methods and the kernel identification algorithms. All these methods discussed above were considered numerous alternatives and related topics which have been developed over the last decade or so.

Generally, compression ignition engine operating on neat vegetable oil and its blend with diesel fuel experience a reduction of engine performance and increase in exhaust emissions due to higher viscosity and lower volatility of vegetable oil than diesel fuel. Vegetable oil is less prone to evaporate, diffuse and mix with the in-cylinder air which eventually reduces the combustion efficiency and produces more emissions of CO and unburned HC. Therefore, this research investigated the potential of guide vane swirl and tumble device (GVSTD) to guide the air entrance to create more organized turbulence inside the fuel injected region to enhance the mixing process of air and vegetable oil. In order to do so, a base model of 3D computational fluid dynamic of internal combustion engine simulation was developed, verified and then simulations were carried with different GVSTD models. The results of turbulent kinetic energy, velocity, vorticity and swirling strength were compared to determine the optimum vane height. This research found that the 2 mm vane height was the optimum vane height with 35° twist angle, four vanes being arranged perpendicularly to each other and 30 mm vane length. Other different heights of vanes also showed improvement but 2 mm height showed the highest number of improvements. This could be due to the airflow pattern in bowl-inpiston head shape was amplified by the airflow pattern produced by the guide vane of 2 mm vane height. The extra turbulence, swirl, vorticity and velocity in the fuel injected region created by the 2 mm height vane is expected to enhance the mixing of vegetable oils with air to improve combustion and reduce CO and unburned HC emissions.
