As network latency rapidly approaches thousands of processor cycles and multiprocessors systems become larger and larger, the primary factor in determining a barrier algorithm’s performance is the number of serialized network latencies it requires. All existing barrier algorithms require at least round trip message latencies to perform a single barrier operation on an -node shared memory multip...

Background: The reactions of the whole organism that occur under the action of accelerations of rectilinear and rotational motion are factors that have a systemic effect on the cerebral blood flow. The use of hurdling performance in the structure of human physical activity can have a significant impact on the tone of the brain vessels, their elasticity and venous outflow in the development of f...

the paper describes an investigation about the application of the new multiple-impedance discontinuities model for optimizing profile diffuser barriers. the new multiple-impedance discontinuities model is much faster than the numerical method, thus it is used in an optimization process. the a-weighted insertion loss was used for the traffic noise spectrum. the result of optimization, which is d...

Barrier algorithms are central to the performance of numerous algorithms on scalable, high-performance architectures. Numerous barrier algorithms have been suggested and studied for Non-Uniform Memory Access (NUMA) architectures, but less work has been done for Cache Only Memory Access (COMA) or attraction memory 2] architectures such as the KSR-1. In this paper, we present two new barrier algo...

The performance of a sound barrier is usually degraded if a large reflecting surface is placed on the source side. A wave-trapping barrier (WTB), with its inner surface covered by wedge-shaped structures, has been proposed to confine waves within the area between the barrier and the reflecting surface, and thus improve the performance. In this paper, the deterioration in performance of a conven...

Infection is the primary source of mortality in burn patients. One of the main treatment methods of burn wound infections is topical antimicrobial therapy, in which drugs have to permeate a dead tissue called eschar. Unfortunately, most antimicrobial agents can not permeate eschar in therapeutic levels. Surprisingly, permeation properties of this barrier and effects of chemical or environmental...
