In this paper, we propose a RAID-disk placement algorithm of coded video data and an efficient disk prefetching method to increase the number of clients who can be serviced interactive operations in the media server. Our placement policy is incorporated with a special bit count control method that is based on repeated tuning of quantization parameters to adjust the actual bit count to the targe...

We present in this paper several extremely efficient and accurate spectral-Galerkin methods for secondand fourth-order equations in polar and cylindrical geometries. These methods are based on appropriate variational formulations which incorporate naturally the pole condition(s). In particular, the computational complexities of the Chebyshev–Galerkin method in a disk and the Chebyshev–Legendre–...

An incompressible potential-flow vortex method has been constructed to analyze the flow field of a ducted wind turbine following that outlined by Lewis (1991). Attention is paid to balancing the momentum change in the flow to the total longitudinal forces acting on the duct-turbine combination: the pressure force on the actuator disk plus the pressure forces acting on the duct, which typically ...

INTRODUCTION Various conventional phenotypic methods and automated systems have been evaluated for extended-spectrum beta-lactamase (ESBL) detection. There is a paucity of data comparing these methods using the same clinical isolates in eastern and north-eastern parts of India. The present study was designed to compare the capacity of six phenotypic methods to detect ESBLs in clinical isolates ...

Starburst is an experimental database management system prototype whose objectives include extensibility, support for knowledge databases, use of memory-resident database techniques, and support for large objects. We describe the structure of the Starburst long field manager, which was designed to manage large database objects such as voice, image, sound and video. The long field manager uses t...

Disk self-gravity could play an important role in the dynamic evolution of interaction between disks and embedded protoplanets. We have developed a fast and accurate solver to calculate the disk potential and disk self-gravity forces for disk systems on a uniform polar grid. Our method follows closely the method given by Chan et al. (2006), in which an FFT in the azimuthal direction is performe...

A new 16-membered macrolide named makinolide B (1) was isolated from Streptomyces sp. MK-19. The structure of makinolide B (1) was determined on the basis of 2D NMR experiments involving DQF-COSY, TOCSY, HSQC, and HMBC methods. Application of the paper disk diffusion method to makinolide B (1) showed weak antibacterial activity against Staphylococcus aureus at the dose of 100 µg/disk.

INTRODUCTION New Delhi metallo-beta-lactamse-1 (NDM-1) producing superbugs create a global public health problem because of their resistance to most antibiotics. This study was conducted to determine the presence of MBL producers, including NDM-1 producers, in Bangladesh, along with the antimicrobial resistance patterns of these organisms. METHODOLOGY Thirty-five isolates resistant to imipene...

In veriication by explicit state enumeration a randomly accessed state table is maintained. In practice, the total main memory available for this state table is a major limiting factor in veriication. We describe a version of the explicit state enumeration veriier Mur' that allows using magnetic disk instead of main memory for storing almost all of the state table. The algorithm avoids costly r...

A new mouse model of anaerobic infection with Bacteroides fragilis alone or in a mixed infection with Escherichia coli is described. It is established by implantation under the skin of a filter paper disk saturated with the appropriate bacterial suspension. The penetration of antibiotics into the implantation site can be detected by assaying the disk. The local infection can be both standardize...
