The micro thrust measurement device based on the cantilever beam can provide the evaluation platform for the mechanical properties of satellite micro thrusters, thus improving the reliability of satellites. With the principle of dividing methods of measurement into direct bearing and plume measuring, this thesis introduces several kinds of typical measuring devices based on the cantilever beam structure...
Determining the time interval for preventive maintenance is one of the most important duties in programming maintenance guides. The purpose of planning the time interval is to keep and restore the reliability of equipment, which means selecting the suitable interval to avoid failures before they occur. Existing methods of determining a fixed-time interval always ignore influences such as cumulative...
This article presents an application of a procedure to modify the intensity distribution by assessing the reliability. There are two potential possibilities that may influence the intensity distribution: (1) For the interpolation error, we generate a measured grid across the calculation region. When the point to station spacing is <5 km, we consider the results precise; however, some points have...
Application-layer multicast (ALM), sometimes called overlay multicast, can help circumvent the limitations in IP multicast and unicast. In this article, we discuss and compare different recovery mechanisms in ALM. The major challenge in loss recovery is how to achieve low residual loss rate with low recovery overhead. As discussed, a promising approach might be a combination of proactive and reactive...
