DYNAMIC bandWIDTH ALLOCATION ALGORITHM UTILIZING full band

Journal of Electronics(China) 2006年第1期23卷 48-53页

作者： Han Guodong Wen Jianhua Wu Jiangxing National Digital Switching System Eng. ＆ Tech. Research Center Info. Eng. Univ Zhengzhou 450002 China

A kind of Dynamic full bandwidth Utilized (DFBU) allocation algorithm is introduced. This algorithm allows a single link to use bandwidth far beyond its fair share bandwidth in a multi-service packet transporting system. Three important parameters as the bound on maximum and minimum bandwidth, the maximum packet delay and the minimum band width utilization are discussed and analyzed. Results of experiments show that the DFBU-algorithm is capable of making a single link in the system to use all the spare bandwidth (up to full-bandwidth) while the performance of fairness and QoS requirement is still guaranteed.

The use of DCEEG to estimate functional and metabolic state of nervous tissue of the brain at hyper- and hypoventilation

引用

World Journal of Neuroscience 2012年第3期2卷 172-182页

作者： Sergey Murik Department of Physiology and Psychophysiology at Irkutsk State University Irkutsk Russia

A pilot study has been made of the simultaneous DC potential and total slow electrical activity changes during modeling various metabolic and functional states of the human brain. The multi-electrode DCEEG recordings have been performed during the hyperventilation (frequent deep one-minute long breathing motions) and the hypoventilation (voluntary breath holding). It has been shown that the ischemic state occurring in hyperventilation is accompanied by the negative shift of DC potential and increase in the EEG rhythms amplitude. A distention of brain vessels during hypoventilation (voluntary breath-hold) and an improvement of blood supply and thus improvement of vital and functional state of neurons gave rise to an increase in the EEG rhythm amplitude too, though against a background of a positive DC-potential shift. Obtained results are considered with context the generation of the qualitatively different functional states of brain cells during hyper- and hypoventilation which is reflected in their resting potential and activity. The conducted study show the prospects for DCEEG and the method we used for DCEEG data processing to understand the character of functional and metabolic changes in the nervous tissue.
