简介：这篇论文为雪崩光电二极管(APD)建议一个控制方法有温度的反向的偏爱赔偿和负担抵抗赔偿。APD察觉电路上的背景光和负载抵抗的影响详细被分析。温度赔偿和负担抵抗赔偿的一个理论模型被建立，它被用于偏导电路设计的APD。这个控制方法对激光范围查找者在车辆上使用了的LD特别合适，这被预言。试验性的结果证实设计在这建议纸能可观地改进范围查找者的表演。CLC数字TN364+.2

简介：这篇论文考虑最佳的预防维护的一个问题和奉献给从已知的存款提取资源的设备的代替时间表。典型例子是油练习，矿铲，等等。至多，在新的存在机械的一代替被允许。这个问题作为一个最佳的控制问题题目被提出到在任何给定的时间的留下的存款是非否定的州的限制。我们证明如果要求，最佳的预防维护，生产率，和存在机械和新机械的代替和抢救时间能被顺序解决一系列free-end-point获得最佳的控制问题。而且，一个算法基于这结果被开发并且过去常解决二个解说性的例子。
