Abstract: Image registration is used to combine two or more partially overlapped images and stitch these images into one panoramic image comprising the whole scene. Image registration is very crucial step in all image analysis tasks in which the final information is obtained from the combination of various data sources. Image registration finds its applications in various fields like remote sensing, medical imaging and computer vision. The reviewed approach is classified according to the four basic steps of feature based image registration: feature detection, feature matching, transformation function design, and image transformation and re-sampling. Image registration can be done by classical methods like wavelet based method, cover method, surface method, correlation method and soft computing based method. The goal of this dissertation is to apply soft computing for the image registration, the method is also evaluated against the classical methods and registration results are compared with the results achieved using soft computing.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 188-191

 

Abstract: In the braced frame, the integrity of the braced connection is very important for the ductile performance and the safety of the frame. But among all the experiments that have been taken on the frame, because of the intensity of stresses, some of the specimens show the brittle behavior, whereas some of the specimen show the ductile behavior. So, it seems that Reduced Beam Section (RBS), in the braced frame may be a suitable solution by concentrating stresses at a location away from the connection. Therefore, in this paper, by using the finite element program ANSYS and with nonlinear static pushover analysis, the effect on the ductility of various types of braced frames have been analyzed using the Reduced Beam Section Profile. In this research paper, the dual moment resisting system of special moment frame with diagonal braced frames and RBS connection has been analyzed. According to this research, diagonal braced frame shows the more ductility than the other braced frames. It also has been seen that the RBS connection enhance the ductile performance and sometimes the torsion also occurs in the beam by keeping the stresses away from the connection.

Volume: I , Issue: III  Publication Year: 2014 , Page(s): 192-194

 

Abstract: Maintenance of road period is defined by the government, but it cannot be able to maintain as per the maintenance policy, thus maintenance cost will be increased due to untimely maintenance. Maintenance includes both physical maintenance activities and traffic service activities. Road transportation remains the main mode of transportation among other modes of transportation in developing countries. The importance of road maintenance in achieving efficient road transport delivery cannot be overemphasized as the consequences of neglect are enormous and costly.

Abstract: Nakagami – m fading channel exploit the varies fading environment for different values of fading parameter m. Nakagami – m distribution approximates a Hoyt or Nakagami – q distribution for m in the range  m ≤ 1 and a Ricean fading for the fading parameter m in the range 1< m <∞ while for m=1 it is act as a Rayleigh Distribution. This Paper proposed the symbol error rate (SER) performance of Space Time Block Code (STBC) and Space Frequency Block Code (SFBC) over Nakagami-m fading Channel. Result shows that SER performance of STBC system is better than SFBC for m≥1 while it outperform as the value of m become less than 1, while SFBC system provide better performance than STBC as Nakagami act as a Fast Fading Channel when the value of m reduces to less than 1.We have implemented the STBC and SFBC systems over Orthogonal Frequency Division Multiplexing (OFDM) using Nakagami Fading Environment.

Abstract: Parking policy is powerful means to manage travel demand and traffic in city centers used by urban planners and policy makers. How visitors to the city center are likely to new policies is important to understand to create proper parking policy. Model to estimate the likely response to two parking policy one is time restriction and other is space restriction parking policy in the urban area of Surat city, Gujarat is presented by this paper. The model is based on the responses of center visitors to a stated preference survey. Two different models were estimated: a binary model and a multinominallogit model. The result suggests that parking measures may be effective in reducing congestion in the busy urban streets. However, they may also have a negative effect as shoppers and other visitors are likely to change their destination which will be decrease the vitality of business.

Abstract: Solar still is a very simple device to convert available brackish or saline water into drinkable water by use of solar energy. Due to its lower productivity, it is not widely used for industrial as well as household purposes. In this work, solar still is coupled with additional basin called double basin with vacuum tubes coupled with lower basin. The use of attachment of additional basin and vacuum tubes, to make a modified solar still for the improvement of distillate output as well as efficiency. In double basin solar still, lower basin attached with vacuum tubes, hence water temperature will be higher, hence latent heat of condensation which is lost to the atmosphere, it is gained and used to evaporate water of the upper basin. Hence, if we consider the cumulative distillate output of both the basin, then distillate output will be higher compared with same size solar still. Also at last, the upper basin is coupled with a photovoltaic system consists of a shaft, which rotates inside the solar still for to create turbulence for increasing the distillate output of solar still.

Abstract: Heat exchanger plays an important role in product quality, energy utilization & system economic and reliable performance. The importance of heat exchangers has increased immensely from the viewpoint of energy conservation, successful implementation of new energy sources & environmental concerns. As a result lots of efforts are being made to increase the performance of heat exchanger. In this project we emphasis on design and fabrication of turbo spin heat exchanger in which new arrangement for flow of hot and cold fluids is employed for design, hot fluid flows in axial path while the cold fluid flows in a spiral path. To measure the performance of the turbo spin heat exchanger, its model is suitably designed and fabricated so as to perform experimental tests and calculate its efficiency and compare it over the shell and tube heat exchanger. The objective of present work is to develop design methodology of turbo spin heat exchanger. The designed turbo spin heat exchanger is required to be developed and experiments will be performed on it to analyze pressure drop, its efficiency and temperature change in hot and cold fluid on shell side and tube side.

Abstract: Typically, an embedded design have a general purpose processor, cache, DMA port and other Bridge port to I/O bus. Advanced Microcontroller Bus Architecture (AMBA) is a I/O bus for interfacing embedded system. Increasing amount of logic that can be placed onto a single silicon die is the development of highly integrated SoC designs. System-on-chip (SoC) designs use bus protocols for high performance data transfer among the Intellectual Property Core. These protocols have advanced features such as unaligned data transfer, pipelining, burst and split transfers. The goal is to design intellectual property core for AMBA AXI4 bus based System-On-Chip Communication Protocol. AMBA AXI4 is the bus that performs best in terms

of throughput, latency and utilization for single or multiple channels. Paper starts with a brief introduction AMBA AHB protocol, AMBA AXI, and simulation result for performance analysis of AMBA AXI (Advanced Extensible Interface) bus protocol.
