Many encrypted database (EDB) systems have been proposed in the last few years as cloud computing has grown in popularity and data breaches have increased. The state-of-the-art EDB systems for relational databases can handle SQL queries over encrypted data and are competitive with commercial database systems. These systems, most of which are based on the(More)
Oblivious RAM (ORAM) is a tool proposed to hide access pattern leakage, and there has been a lot of progress in the efficiency of ORAM schemes; however, less attention has been paid to study the applicability of ORAM for cloud applications such as symmetric searchable encryption (SSE). Although, searchable encryption is one of the motivations for ORAM(More)
Known Oblivious RAM (ORAM) constructions achieve either optimal bandwidth blowup or optimal latency (as measured by online roundtrips), but not both. We are the first to demonstrate an ORAM scheme, called Bucket ORAM, which attains the best of both worlds. Bucket ORAM simultaneously achieves a single online roundtrip as well as constant overall bandwidth(More)
L-asparaginase, an anti-leukaemic drug that has been approved for clinical use for many years in the treatment of childhood Acute Lymphoblastic Leukaemia (ALL), is obtained from bacterial origin (Escherichia coli and Erwinia carotovora). The efficacy of L-asparaginase has been discussed for the past 40 years, and an ideal substitute for the enzyme has not(More)
Detection and Tracking of human being is a very important problem in Computer Vision. Human robot interaction is a very essential need for service robots where robots are required to detect and track human beings in order to provide the required service. In this paper we present an improved novel approach for tracking a target person in crowded environment.(More)
Coating growth and mechanical properties of nanolamellar Cr2AlC coatings at various sputtering power were investigated in the present study. Cr2AlC coating was deposited on the IN 718 superalloy and (100) Si wafers by DC magnetron sputtering at different sputtering powers. The structure and properties were characterized using X-ray diffraction (XRD),(More)
Automated scene analysis can classify images into semantically meaningful categories and can be achieved by various means [1][2]. In this study, we have used spatial envelope to extract features from 529 images of 3 semantic scene categories i.e. indoor, landscape and outdoor scenes. Spatial envelope was represented by a Gist descriptor, resulting in 256(More)
The rhizospheric zone abutting plant roots usually clutches a wealth of microbes. In the recent past, enormous genetic resources have been excavated with potential applications in host plant interaction and ancillary aspects. Two Pseudomonas strains were isolated and identified through 16S rRNA and rpoD sequence analyses as P. fluorescens QAU67 and P.(More)
Scattering of electromagnetic plane waves from a coated perfect electromagnetic conductor PEMC circular cylinder placed under perfect electric conducting PEC wide double wedge is presented. It is assumed that the distance between the two wedges is large as compared to the wavelength. Therefore, the field at an observation point can be considered to be(More)
