The present paper is devoted for the study of propagation of Loves waves in a compressible viscous liquid layer of thickness h2 and co-efficient of viscosity ηι bounded by an infinite transversely isotropic poroelastic layer and a transversely poroelastic half-space. The equations of motion in transversely isotropic poroelastic solid have been formulated in the frame work of Biots theory. The secular equation has been obtained and is discussed in the limiting case h2 → 0, ηι → 0 such that the ratio h2/ηι is a constant. Further, secular equation is observed for a case of the poroelastic layer is in welded contact with half-space when the thickness of liquid layer is zero for finite co-efficient of viscosity. Several other special cases have been discussed.

Torsional vibrations of annular poroelastic circular plates are studied in the framework of Biot's theory of wave propagation in porous solids. The frequency equation of torsional vibrations is same for pervious and impervious surfaces. The frequency equation of torsional vibrations is obtained by using the traction free boundaries and edges of the annular circular plate. Non-dimensional frequency of annular plate is computed as a function of aspect ratio. The frequency equation is discussed for first two modes. Frequency equation of torsional vibrations of uniform circular poroelastic plate is obtained as a particular case of the annular plate. Resonant frequency of infinite poroelastic plate is obtained as a limiting case of annular plate. The expressions for phase velocity and attenuation are obtained and these are computed for two different poroelastic materials as a function of frequency in presence of dissipation. Phase velocity is almost same for the considered poroelastic materials and dissipations. Results of previous study are obtained as a particular case of the present investigation.

Day by day scanned documents are increasing to preserve the old literatures digitally, especially Telugu literatures. During this scanning so much noise comes into the scanned documents, in addition to noise, other geometry distortions, scale changes will take place while scanning. In this scenario, general optical character recognition (OCR) systems fail to extract the text due to these problems. So, an efficient mechanism is needed to extract TELUGU text. Towards this, in this work, an efficient algorithm to search for the TELUGU text has been proposed, which uses Speeded Up Robust Feature Transform (SURF) to extract descriptors and uses the KD tree algorithm for matching purpose. The presented results prove the robustness of the system under different noise and partial occlusion by strip-lines, orientation changes like rotation etc. © 2016 IEEE.

Cloud Computing has become a major part of all organizations throughout the world because of the services offered such as Iaas, Saas, Paas and wide availability of these services. In spite of the benefits of cloud services they must consider how the security and privacy aspects are ensured, as users are often store some sensitive information with cloud storage providers which may be un trusted. In this paper, we are going to discuss about a novel approach where the Protection to data as included as a new service which will reduce the per application development cost to provide a secure environment and also provides secure access to data stored in public clouds. © Springer India 2016.

In this Paper, HKFCM Clustering algorithm was used to generate an initial contour curve which overcomes leaking at the boundary during the curve propagation. Firstly, HKFCM algorithm computes the fuzzy membership values for each pixel. On the basis of HKFCM the edge indicator function was redefined. Using the edge indicator function the biomedical image was performed to extract the regions of interest for advance processing. Applying the radon transform on the output image will be shown with experiment demonstration. The above process of segmentation showed a considerable improvement in the evolution of the level set function. © Springer International Publishing Switzerland 2015.

Content Based Image Retrieval is a technique of automatic indexing and retrieving of images. In order to improve the retrieval performance of images, this paper proposes an efficient approach for extracting and retrieving color images. The block diagram of our proposed approach to content-based image retrieval (CBIR) is given first, and then we introduce Histogram Euclidean distance (L2 distance), Cosine Distance and Histogram Intersection which are used to measure the image level similarity. The combined features of finding a set of weights of different distances represented by mini-max algorithm is used to declare the best match to the query image. Query images are used to retrieve images similar to the query image. Comparison and analysis of performance evaluation for features and similarity measures for the retrieved images with ground truth are shown. This proposed retrieval approach demonstrates a promising performance. Experiment shows that combined features are superior to any one of the three. © Springer International Publishing Switzerland 2014.

The most effective technique to reduce dynamic power is the supply voltage reduction by technology scaling which reduces threshold voltage. Under deep submicron technology, reduction in threshold voltage increases leakage currents, gate tunneling currents and leakage power in standby mode. Most of the handheld devices have long standby mode cause leakage current contributing to leakage power dissipation. In this paper, various leakage power reductions, charge recycling techniques, data retention of memories. Various Power gating techniques are discussed in detail. © Springer India 2016.

A novel approach for image segmentation is proposed in which, the output of Image Resolution Enhancement using Dual-Tree Complex Wavelet Transform is given as input to the Fuzzy C-Means Clustering technique. The FCM calculates fuzziness for the belongingness of each image pixels i.e., FCM was used to generate an initial contour curve which removes leaking at the boundary during the curve propagation. Based on FCM the edge indicator function was defined. The edge indicator function of a image was performed to extract the boundaries of objects on the basis of the pre segmentation. Fuzzy clustering methods quantitatively determine the affinities of different objects with mathematical methods, described by a member function, to divide types objectively. Therefore, the proposed method is computationally efficient. © 2014 IEEE.

Cerium oxide thin films are deposited on quartz substrate using pulsed laser deposition technique at a substrate temperature 973 K with an oxygen partial pressure of 0.2 Pa. The properties of the grown films mainly depend on the quality of the deposition. In the present investigation the deposition is carried out using excimer laser (KrF). To improve the microstructure and crystallite properties the deposited thin films are annealed at 1073 K for 2 h. The prepared and annealed thin films characterized by X-ray diffraction, atomic force microscope (AFM) and UV-visible spectroscopy: X-ray diffraction analysis confirmed the polycrystalline nature of the thin films. Crystallite size, lattice constant and texture coefficient are calculated. The film thickness is measured using XP-1 stylus profiler, optical band gap has been carried out and surface roughness has been estimated from AFM. © 2015, Pleiades Publishing, Ltd.
