摘要:... When producing CBM, the working level within a CBM wellbore annulus needs to be monitored to dynamically adjust the gas drainage and extraction processes. However, the existing method of measuring the working level does not meet the needs of accurate adjustment, so we desig...

摘要:Abstract(#br)The purpose of this paper is to analyze systems composed of several parts, at differentworking levels. At time t, only the performance level of the system, exactly determined inan additive way by the level of the unobservable components, can be observed. We obtainthe...

摘要:Abstract(#br)Recently, we reported that voluntary resistance wheel running with a resistance of 30% of body weight (RWR), which produces shorter distances but higher work levels, enhances spatial memory associated with hippocampal brain-derived neurotrophic factor (BDNF) signa...
