Low encoding/decoding complexity is essential for practical RAID-6 storage systems. In this paper, we describe a new coding scheme, which we call Rotary-code, for RAID-6 disk arrays. We construct Rotarycode based on a bit matrix-vector product similar to the Reed-Solomon coding, and provide the geometry encoding method and detailed non-recursive decoding algorithms. The capability of two-disk f...

Rotary ultrasonic machining is one of the nontraditional machining processes for advanced ceramics. Currently available in literature are publications on theoretical and experimental studies on material removal rates in rotary ultrasonic machining. However, there is no report on the systematic study of the cutting force in rotary ultrasonic machining. Furthermore, the effects of some process pa...

Rotary ATPases are molecular rotary motors involved in biological energy conversion. They either synthesize or hydrolyze the universal biological energy carrier adenosine triphosphate. Recent work has elucidated the general architecture and subunit compositions of all three sub-types of rotary ATPases. Composite models of the intact F-, V- and A-type ATPases have been constructed by fitting hig...

Oil circulation rate is a crucial factor affecting air-conditioning system performance and rotary compressor reliability. This paper illustrates several design concepts to reduce oil circulation rate and discusses their effectiveness. This paper also discusses how to measure the rate in terms of accuracy and repeatability with a statistical significance.

The bacterial flagellar motor of Escherichia coli is a nanoscale rotary engine essential for bacterial propulsion. Studies on the power output of single motors rely on the measurement of motor torque and rotation under external load. Here, we investigate the use of magnetic tweezers, which in principle allow the application and active control of a calibrated load torque, to study single flagell...

Future lithography systems must produce microchips with smaller feature sizes, while maintaining throughputs comparable to those of today’s optical lithography systems. This places stringent constraints on the effective data throughput of any maskless lithography system. In recent years, we have developed a datapath architecture for directwrite lithography systems, and have shown that compressi...

UNLABELLED The search for new instruments to promote an appropriate cervical preparation has led to the development of new rotary instruments such as TripleGates. However, to the best of the authors' knowledge, there is no study evaluating TripleGates effect on the "risk zone" of mandibular molars. OBJECTIVES The aim of this study was to evaluate the effects of a crown-down sequence of Gates-...

The present paper is concerned with the free vibration analysis of double-walled carbon nanotubes embedded in an elastic medium and based on Eringen's nonlocal elasticity theory. The effects of the transverse shear deformation and rotary inertia are included according to the Timoshenko beam theory. The governing equations of motion which are coupled with each other via the van der Waals interla...

The Viscous Beam is a wearable tremor-suppression orthosis that applies viscous resistance to motion of the wrist in flexion and extension. The orthosis reduces tremor amplitude and is small enough to be worn under the sleeve of a shirt. Hand and forearm cuffs couple the damper to the user. The cuffs permit full thumb and finger motion, wrist flexion and extension, and forearm pronation and sup...
