Five-axis computer numerical control (CNC) machine tools (three linear and two rotary axes) are ideally suited to the fabrication of complex work pieces, such as dies, turbo blades, and cams. The locations of the axis average line and centerline of the rotary axes strongly influence the performance of these machines; however, techniques to compensate for eccentric error in the rotary axes remai...

were given in the Indian Medical Gazette, during 1868. Fuzzool, aged 60, Mussulman cultivator, admitted 6th December. About 30 years ago a small abscess formed under the arch of the left foot, it continued to discharge after being opened, and about a year after another absccss formed in the middle of the heel; gradually those abscesses extended to the malleoli and dorsum of the foot, dischargin...

Induced-strain materials can produce very large forces and, hence, large energy density, but small actual displacements. A new concept for obtaining large-amplitude rotary displacements from small linear displacements generated by induced-strain material stacks is proposed. The concept utilizes the theory of twist-warping coupling in thin-wall open tubes. The theory of the proposed solid-state ...

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...

introduction: the purpose of this study was to evaluate the efficacy of three methods in removal of resilon/new epiphany self-etch (se) soft resin endodontic obturation system. materials and methods: thirty extracted single rooted human teeth were prepared for endodontic treatment and obturated with resilon/epiphany se. the roots were randomly divided into three groups; group 1 roots were retre...
