The authors present a case of unusually aggressive adenoid cystic carcinoma of the head and neck. The patient presented with sciatica one year after initial diagnosis. She was otherwise asymptomatic. Complete work-up for bone involvement, included bone scan and MRI. The patient had painful osteolytic sacral metastasis and asymptomatic thoracic (T5) vertebral metastasis revealed by a typical cur...
Refrigerated display cabinets as a type of cooling system is preferable commonly in food shops and grocery store to prevent foods from warm air. They do not have much more efficient compared the with glass doors because interactions between air curtain. This paper presents experimental numerical methods seek energy performance horizontal refrigerated terms design parameters. Two geometry with/w...
This paper examines methods for limiting occupational silica exposures for roof bolting personnel in underground coal mining. A canopy air curtain and an air tube were evaluated as means to provide filtered air over the breathing zone of these personnel. Laboratory testing showed that dust reductions beneath the air curtain and air tube approached 60 percent and 40 percent, respectively, with l...
Using RXTE and ASCA data, we investigate the roles played by occultation and absorption in the X-ray spin pulse profile of the Intermediate Polar PQ Gem. From the X-ray light curves and phase-resolved spectroscopy, we find that the intensity variations are due to a combination of varying degrees of absorption and the accretion regions rotating behind the visible face of the white dwarf. These o...
The definition of hazard area, centered inside the LNG stations, is essential for risk assessment in LNG industry. In this study, computational fluid dynamics (CFD) simulations have been conducted for the two main LNG hazards, LNG flammable vapor dispersion and LNG pool fire radiation, to determine the hazard exclusion area. The spatial and temporal distribution of hazard in complex spill scena...
We propose a novel model for curtain real-time animation, which not only significantly reduces the time of rendering, but is also able to maintain visually appealing results. Conventional physically based models for cloth simulations are typically dense sheets of interwoven strings, with particles of finite mass at the intersections. While it seems to be an accurate model for cloth, it also imp...
The last decade has seen an increasing interest in developing and employing service robots for building maintenance. Cleaning the curtain walls of high-rise buildings is always very dangerous and strenuous. This paper describes three different kinds of cleaning robots developed by the authors cooperated with the researchers in Robotics Institute of BeiHang University. Sky Cleaner 3 for the glas...
