Ad hoc networks are multi-hop wireless networks without a pre-installed infrastructure. Such networks are widely used in military applications and in emergency situations as they permit the establishment of a communication network at very short notice with a very low cost. Video is very sensitive for packet loss and wireless ad-hoc networks are error prone due to node mobility and weak links. H...

The memory consistency model supported by a multiprocessor directly affects its performance. Thus, several attempts have been made to relax the consistency models to allow for more buffering and pipelining of memory accesses. Unfortunately, the potential increase in performance afforded by relaxing the consistency model is accompanied by a more complex programming model. This paper introduces t...

Multimedia streams usually require prefetching and buffering to ens’ure steady, glitch-fnee d e h e r y to audio and video displays, but buffering ca’uses undesirable latency. This latency may be manifested as startup delays, glitches, dropouts, and loss of synchronization. I n interactive media presentations .where there are a small number of choices, alternative streams can be prefetched to r...

background: human immunodeficiency virus (hiv) causes severe immunosuppression due to progressive decrease in the cd4 t lymphocyte cells during the course of the disease and this affects all the body systems including glandular secretions. a number of lesions affecting the salivary glands have been noted in hiv infection. the objective of this study was to evaluate the salivary ph and the buffe...

a study of substantial anthropogenic related pollution in the coastal samut prakarn province (thailand) was carried out focusing on the bang pu nature reserve (remnant mangrove wetland) using a remote sensing (geospatial) technique. statistical regression models were developed between biochemical parameters of sample point and related reflectance data obtained from satellite imagery (landsat tm...

The buffering capacity of tears collected from six young, healthy subjects was assessed using a microtitration technique. Each subject provided, on six separate occasions, about 100 microliter of tears, collected in small amounts and with minimal mechanical stimulation over several hours. The pH of the total stirred pool of tears from each subject was determined at the outset. This pool of tear...
