We present a new multithreaded implementation for the computationally demanding direct volume rendering (DVR) of volumetric datasets on desktop multicore processors using ray casting. The new implementation achieves interactive rendering of very large volumes, even on high resolution screens. Our implementation is based on a new algorithm that combines an object order traversal of the volumetri...

conclusions the best balance between detection rate of prostate cancer and infectious complications of biopsies achieved in twelve-core biopsy protocol. twelve-core biopsy enhances the rate of prostate cancer detection with minimum adverse effects. patients and materials transrectal ultrasonography (trus) guided biopsy was performed in 180 patients suspicious for prostate cancer due to either a...

Short term immobilization of the lower limb is associated with increased corticospinal excitability at 24 hours post cast removal. We wondered whether daily stimulation of the motor cortex might decrease brain reorganization during casting. We tested the feasibility of this approach. Using transcranial magnetic stimulation (TMS), resting motor threshold and recruitment curves were obtained at b...

A two-year program was conducted to develop and commercially manufacturing technologies to: • Enable significant reductions in the costs of castings, • Increase the complexity and dimensional accuracy of castings, and • Reduce the development times for delivery of high quality castings. implement selected casting The industry-led R&D project was cost shared with NASA's Aerospace Industry Techno...

The benefits of energy and operational cost savings from using copper rotors are well recognized. The main barrier to die casting copper rotors is short mold life. This paper introduces a new approach for manufacturing copperbar rotors. Either copper, aluminum, or their alloys can be used for the end rings. Both solid-core and laminated-core rotors were built. High quality joints of aluminum to...

Ceramic cores are widely used in investment casting, and ideal properties of essential for high-quality castings. Under the circumstances requiring thick cores, solid likely to encounter deformation cracking defects due accumulation shrinkage. Therefore, with superiority ceramic stereolithography producing complex parts, hollow lattice structures were designed fabricated. The dimensional accura...
