Abstract: Joint orientation, Joint roughness, number of joints and location of joint affects the strength of jointed rocks. Point load index test needs less sample preparation, easy to handle and quick test while comparing with uniaxial compressive test. Lot of researchers comes out with a lot of correlations between uniaxial compressive strength and point load index for intact rocks. But there is only few reported research work in jointed rocks............

Abstract: Buildings alone the wind speed is accelerated above them in the urban environment. This fact can be utilized as an energy resource. The integration of wind turbines on buildings, is becoming a new possibility, and has begun to be studied in university research centers in wind energy, mainly in Europe. In this paper the correct location of wind turbines is assessed by wind tunnel tests on two forms of buildings that can catch the wind in the atmospheric boundary layer........

Abstract: This paper deals with the dynamics of a vibration-driven unidirectionally moving wheeled robot. A dynamic model of the robot is proposed and the equations governing the motion are derived. The conditions for one-way motion of the robot are likewise obtained. Furthermore the settings for the motion of the wheels with no slippage are also stated. Numerical experiment with the dynamic model of the robot assumed to have linear elastic and dissipative characteristics is conducted and the results obtained are visualized by means of 2D and 3D graphs.......

Abstract: In contrast to many other environmental problems, noise pollution continues to grow and is a pollution which keeps on developing and is joined by an expanding number of objections from individuals presented to the noise. The development in noise pollution is unsustainable in light of the fact that it includes direct and in addition cumulative, adverse health effects. The study is completed in the inside heart of the Anand City ( Bhalej road – Mahendra shah doctor's facility to Grid) and is an eye-opener to see and comprehend the significance of noise pollution in the wake of its evil impact on the life of the general population........

Abstract: Combustion reaction in the internal combustion engine depends on many different variables, one of the most important factors in an efficient combustion reaction is the ability of the reactants, the fuel molecules and the oxidant molecules, to interact with each other, Most fuels used in internal combustion engines are in liquid state, like gasoline, diesel, biofuels, and since combustion occurs in the gas phase, achieving a substantially even dispersion of fuel molecules among oxidant molecules can prove difficult due to the vapor pressure of the liquid, Therefore, an efficient combustion reaction would involve providing for the fuel molecules to be substantially and evenly dispersed throughout the oxidant molecules, thereby allowing sufficient.......

Abstract: This paper describes a sensor network platform for pipeline system monitoring. Pipeline systems are widely used for distribution and transportation of petroleum, natural gas, water, and sewage. Leaks and ruptures due to an aging and fast decaying pipeline system infrastructure cost millions of dollars a year; they also make clear the necessity for continuous, automatic monitoring systems that can provide early detection and early warning of defects, such as corrosion and leaks, before they reach the magnitude of a major disaster.......

Abstract: The heat transfer performance is one of the prominent research areas in thermal engineering. To transfer heat from low temperature reservoir to high temperature reservoir, numbers of refrigerants were used by different refrigeration systems. Their environmental effects like toxicity, Flammability and high pressure made them more hazardous according to safety and environmental issues. For society's standard of living the availability and application of refrigeration technology is important. Preserving food products and medical appliances' are key contributors to quality of life........

Abstract: Electrical discharge machining (EDM) is one of the earliest non-traditional machining processes. EDM process is based on thermo electric energy between an electrode and the workpiece. The important process parameters in this technique are current,discharge pulse on time, discharge pulse off and gap voltage. The values of these parameters significantly affect the machining outputs material removal rate. Optimization is one of the techniques used in manufacturing sectors to arrive for the best manufacturing conditions, which is an essential need for industries towards manufacturing of quality products at lower cost.......

Abstract: Rapid population growth and modernization in human lifestyles are resulting in increased energy consumption. The power generation and transportation sectors are the main consuming source of energy. The diesel engine plays a major part of both of these sectors throughout the world. Petroleum based fuels worldwide have not only resulted in the rapid depletion of conventional energy sources, but also have caused severe air pollution. Hence it has become necessity to go for an alternate fuel.......

Abstract: Environmental pollution is a great hazard to our eco-system which is also being adversely affected by emissions from internal combustion (I.C.) engines. In the present work, an attempt has been made towards the application of Back Propagation Neural Network (BPNN) for predicting the CO emission from a diesel engine so that better control of the engine parameters may be performed to minimize the level of emission. The data collected for training the Neural Network (NN) were compression ratio, injection timing, load, cylinder peak pressure, crank angle at peak pressure, temperature of cooling water, and temperature of exhaust gas.......
