Parameter sensitive analysis of flexible pavement

Abstract: This paper describes the usefulness of FEM for exploring the parameter sensitive analysis. Using 2D axisymmetric analysis, the critical performance parameters are examined by varying the thickness and material properties of different layers of flexible pavement. Hypothetical pavement sections are also analyzed with a view to check the sensitivity of horizontal axisymmetric extent and refinement of mesh. The developed computer program after validation is used to calculate the horizontal tensile strain at the bottom of the bituminous layer (BL) and the vertical compressive strain at the top of the subgrade. These computed strains are incorporated in the fatigue and rutting criteria recommended in Indian Road Congress (IRC: 37-2012) to estimate the pavement life for various hypothetical conditions. Tensile strain at the bottom of BL and compressive strain on top of the subgrade decreases with an increase in the thickness of BL, which results in increase of fatigue and rutting lives. An increase in thickness of the base layer and the increase in its elastic modulus reduces the damage due to rutting, while it has less effect on damage due to fatigue. Such type of analysis proves beneficial for designing a pavement, keeping equilibrium between fatigue and rutting lives.

Distributed energy efficient routing in ad hoc networks

Abstract: Ad hoc networks are non-infrastructure networks consisting of mobile nodes. Since the mobile nodes have limited battery power, it is very important to use energy efficiently in ad hoc networks. In order to maximize the lifetime of an ad hoc network, traffic should be sent via a route that can avoid nodes with low energy while minimizing the total transmission power. In addition, considering that the nodes of ad hoc networks are mobile, on-demand routing protocols are preferred for ad hoc networks. Existing power-aware routing algorithm need to be modified to meet the requirement of energy efficient routing and also this on demand protocol should be addressing mobility issue. In this paper we propose a novel on-demand power aware routing algorithm, DEEAR (Distributed Energy-efficient AODV Routing) protocol. DEEAR prolongs the network lifetime by compromising between minimum energy consumption and fair energy consumption without additional control packets. DEEAR also improves network throughput as well as improvement in data packet delivery ratio.

Cloud storage architecture

Abstract: Designing storage architectures for emerging data-intensive applications presents several challenges and opportunities. Tackling these problems requires a combination of architectural optimizations to the storage devices and layers of the memory/storage hierarchy as well as hardware/software techniques to manage the flow of data between the cores and storage. As we move deeper into an era in which data is a first-class citizen in architecture design, optimizing the storage architecture will become more important. Cloud Storage Architecture is major topic in now a day because the data usage and the storage capacity are increased double year by year. So that some of the major companies are mainly concentrated on demand storage option like cloud storage. The existing cloud storage providers are mainly concentrated on performance, cost issues and multiple storage options.

Selection of Wavelets for Medical Image Compression

Abstract: Medical images carry huge and vital information. It is necessary to compress the medical images without losing its vital-ness. Wavelet transform is preferable in the field of compression because of much more information of image can be retraced by it than any other transform. There are varieties of wavelets available but always there is a question in designers mind about which type of wavelet should I select for my design? Here we have focused on the selection of wavelet for compression of medical images. Various wavelets have been used for compression and we have done quality analysis on reconstructed image. Based on results we have found out the best suitable wavelet for medial image compression.
