This idea of implementation is to use renewable energy from environment for generating electricity from one of the renewable energy sources. Now a day many of items are electronic which requires electric power to operate. If we can generate that amount of electric power that can be used to operate low power electronics device, it will be very useful and notable amount of power can be saved. For this purpose we are using stray sound energy that can be converted into electric energy with the help of energy conversion methods and can be used further. A piezo-electric sensor is used as a transducer to convert sound energy into electrical energy and that energy is used to operate low power device. This idea is very simple, handy and convenient and can be used during festivals, parties or noisy industries etc. The output of a transducer is enhanced by the use of signal conditioning device. The resultant electrical energy is stored in a battery such that it can be used for further applications.

In present days the manufacturers are facing the challenges in attaining the high productivity, quality and overall economy in the field of manufacturing by machining. Among all the machining processes available drilling is a major and common hole making process and it uses the drill bits to cut or enlarge the holes in solid materials such as wood or metal. The present work is to investigate the effect of the drilling process parameters on the multiple responses of Volume of material removal rate (VMRR) and surface roughness (Ra). A series of experiments were carried out on AA6082 material using carbide twisted drills on CNC machine. Speed, feed, depth of cut and drill sizes are considered as the process parameters and taguchi’s standard L16 orthogonal array (OA) has been followed for conducting the experiments. The optimal setting of process parameters was done by employing taguchi method coupled with the desirability function analysis (DFA) and analysis of variance (ANOVA) methods. From the results, it is concluded that speed is the most influencing factor for the combined desirability index value. The optimal combination of process parameters for multi-response value is obtained at speed of 2000 rpm, feed of 400 mm/min, depth of cut of 12 mm and drill size of 13mm.

A structure can be classified as irregular if it contains irregular distributions of mass, stiffness and strength or due to irregular geometrical configurations. Many buildings in the present scenario have irregular configurations both in plan and elevation. This in future may subject to devastating earthquakes. Codes suggests the different limits for these irregularities like as per IS 1893:2002, a storey in a building is said to contain mass irregularity if its mass exceeds 200% than that of the adjacent storey. In case, it is necessary to identify the performance of the structures to withstand against disaster for both new and existing one. This study is concerned with the effects of various vertical irregularities on the seismic response of a structure. The objective of the project is to carry out Response spectrum analysis (RSA) of vertically irregular RC building frame structure by the use of STAAD.PRO software of structure design. This study is limited to reinforced concrete framed structures subjected to seismic loads (dead load, live load and earthquake load). For this, RC frames of G+9 multi-story buildings are considered. All the frames are assumed to be located in zone V. The seismic parameters such as storey drift, base shear, peak story shear and top node displacement of irregular buildings are compared with that of a regular building. Result found from the response spectrum analysis that in irregular shaped building displacements are more than that of regular shaped building. The overall performance of regular building is found better than irregular building. This study may be used for designing new irregular building structures and for analyzing existing irregular building.

Almost everyone in this world has at least once used the conventional manual transmission system and knows its logic of working. Everyone knows that the dock gear gets engaged to the selected gear and the power is transmitted through this gear. But not many know about what exactly happens inside the transmission gearbox. All the moving parts we know of are the engine, clutch, the selected gear and the output shaft of the transmission gearbox. But there is more movement than that is thought to be, the counter shaft or the lay shaft moves constantly and it has all the gears on it which are moving too, these gears eventually give motion to the non-engaged gears on the output shaft. There are several different conditions here too, such as when the clutch is engaged or disengaged, whether the vehicle is static or is in motion and whether the transmission gearbox is set at some gear or is in the neutral condition. Once all these various actions taking place in the vehicle transmission are identified, we can move ahead to point out the advantages and disadvantages of this conventional manual transmission system. Through this we can discuss about the clutch present in this transmission system and how it proves to be very helpful in this system. Thus, through this paper we all come to know that this world is full of endless possibilities; there are still a lot of methods to modify and improve this transmission system.

Rolling element bearings are essential for rotating machinery. The spherical roller bearing (SRB) is one variant seeing increasing use, because it is self-aligning and can support high loads. It is becoming increasingly important to understand how the SRB responds dynamically under a variety of conditions. This doctoral dissertation introduces a computationally efficient, three-degree-of-freedom, SRB model that was developed to Predict the transient dynamic behaviors of a rotor-SRB system. In the model, bearing forces and deflections were calculated as a function of contact deformation and bearing geometry parameters according to nonlinear Hertzian contact theory. The results reveal how some of the more important parameters; such as diametral clearance, the number of rollers, and osculation number; influence ultimate bearing performance. Distributed defects, such as the waviness of the inner and outer ring, and localized defects, such as inner and outer ring defects, are taken into consideration in the proposed model. Following model verification, a numerical simulation was carried out successfully for a full rotor-bearing system to demonstrate the application of this newly developed SRB model in a typical real world analysis. Accuracy of the model was verified by comparing measured to predicted behaviors for equivalent systems.
