Abstract:

In this paper the effectiveness of a solid particle damper to control structural vibration is experimentally investigated. The vibration control performance and its influencing parameters are examined by a Multi Degree of Freedom (MDOF) structure attached with a particle damper (PD) under horizontal excitation. In a particle damping system damping is achieved using solid particles or granules and is a passive damping method. Here the enclosure filled with particles is attached to the primary structure undergoing vibration. As the primary structure vibrates, particles undergo inelastic collision within the enclosure resulting high amount of energy dissipation. Based on the analytical study of undamped frame in ANSYS WORKBENCH, dimensions of the frame were fixed and shake table study of a two storied steel frame with and without damper system are carried out. Results shows that effectiveness of damping depends on various parameters like mass, particle size, shape etc. The effectiveness is compared with a friction damper (FD) and is observed that PD is more efficient than

Abstract:

Petroleum based fuels play a vital role in rapid depletion of conventional energy sources. Along with their increasing demands, these are also major contributors of air pollution which is contributing to greenhouse effect and consequently to ozone layer depletion.
Major portion of today's energy demand in India is being met with fossil fuels. Hence, it is high time that alternative fuels for engines should be derived from different indigenous sources. As India is an agricultural country, there is a wide scope for the production of vegetable oils (both edible and non-edible) from different oil seeds.
This paper is based on recommending an alternate fuel for diesel engines. Expectations have been high for the production of biodiesel from the Jatropha oil-crop. Jatropha is promoted as a drought and pest resistant crop, with the potential to grow on degraded soils with a low amount of inputs. These characteristics encourage hope

Abstract:

Anintegration and operation of a three-phase inverter with twobuck/boost maximum power point trackers (MPPTs) for dc-distribution applications. In a dc-distribution system, a three phase inverter isrequired to control the power flow between dc busand three phase ac grid, and to regulate the dc bus to a certainrange of voltages. A droop regulation mechanism according to the inverter inductor current levels to reduce capacitor size, balance power flow, and accommodate load variation is proposed. Since thephotovoltaic (PV) array voltage can vary from 0 to 5000 V, especially with thin-film PV panels, the MPPT topology is formed with buck and boost converters to operate at the dc-bus voltage around 4000 V, reducing the voltage stress of its followed inverter. Additionally, the controller can online check the input configuration of the two MPPTs, equally distribute the PV-array output current to the two MPPTs in parallel operation, and switch control laws to smooth out mode transition. A comparison between the conventional boost MPPT and the proposed buck/boost MPPT integrated with a PV inverter is also presented. Asingle-phase bidirectional inverter with two buck/boost maximum power point trackers (MPPTs) by using the closed loop circuit. This project is workout bySimulink using mat lab.

Abstract:

Railways are the popular mode of Transport in almost all major cities of the World. Railways are the most widely used and comfortable modes of transportation system. The major cause for railway accidents is collision of trains on the same track. The main aim of this anti collision system is to identify collision points and to report these error cases to main control room nearer to the station as well as grid control station. Majority of accidents occurred due to improper communication among the network between drivers and control room, due to wrong signaling, worst atmospheric condition, immediate change of route. The train driver doesn't get proper information in time leading to hazardous situations. So this system by using zigbee protocol provides communication in between trains, which provide information or track id of one train to another train to avoid collision.

Abstract:

This paper presents a power factor corrected (PFC) bridgeless (BL) buck–boost converter-fed brushless direct current (BLDC) motor drive as a cost-effective solution for low-power applications. An approach of speed control of the BLDC motor by controlling the dc link voltage of the voltage source inverter (VSI) is used with a single voltage sensor. This facilitates the operation of VSI at fundamental frequency switching by using the electronic commutation of the BLDC motor which offers reduced switching losses. A BL configuration of the buck–boost converter is proposed which offers the elimination of the diode bridge rectifier, thus reducing the conduction losses associated with it. A PFC BL buck–boost converter is designed to operate in discontinuous inductor current mode (DICM) to provide an inherent PFC at ac mains. The performance of the proposed drive is evaluated over a wide range of speed control and varying supply voltages (universal ac mains at 90–265 V) with improved power quality at ac mains. The obtained power quality indices are within the acceptable limits of international power quality standards such as the IEC 61000-3-2. The performance of the proposed drive is simulated in MATLAB/Simulink environment, and the obtained results are validated experimentally on a developed prototype of the drive.

Abstract:

Level of Service (LOS) is an important measure of performance of highways. The primary measure of service quality for two lane highways based on highway capacity manual are percent time spent following and average travel speed which are not directly based on user perception. In addition to speed and delay the road users perceive other attributes in their subjective determination of LOS. A methodology based on fuzzy set approach and fuzzy clustering is presented to determine the LOS that explicitly accounts for user perception. Several attributes contributing to road user perceptions of LOS were identified using a questionnaire survey and composite level of service was obtained by combining all attributes together using fuzzy weighted average and fuzzy C means clustering techniques. The levels of service obtained were compared with that obtained using field procedure recommended in HCM 2000.

Abstract:

A robust watermark scheme for copyright protection is proposed in this paper. The present method selects the best block of image for watermark embedding by comparing luminance value of colored image and block. The watermark is embedded in the selected pixel blocks by using block pixel differencing LSB substitution method. The proposed approach overcomes the weak robustness problem of embedding the watermark in the spatial domain LSB substitution method. Further the watermark extraction does not require the original image as in the case of many digital watermarking methods. The experimental results indicate that the proposed system is better in terms of image quality and robustness against various attacks.

Abstract:

With people's increasing demand of nightlife activities, the nightscape has become more important than ever to enhance the image of city. In this study, we tried to analyze the effects and influence of the landscape lighting that produced the nightscape and pointed out that the optimal nightscapes along the LRT (Light Rail Transit) line. We selected the urban landscapes along the LRT wayside as the research objects, used the SD (Semantic Differential) technique to compare the difference between the daytime and the nighttime landscapes by the vision engineering and measurement psychology. As a result, it became clear as follows: 1) image evaluation of the nightscapes got higher estimation than that of daytime landscapes. The importance of the nightscape has been recognized once again; 2) landscape lighting played the important role in the charming nightscape; 3) the optimal nightscapes along the LRT routes could be chosen with the results of factor analysis.
