简介：这份报纸为高速度的电的火车调查最小精力的开车问题，然后建议三阶段的最佳的策略。首先，一个切换的系统模型被介绍在高速度的电的火车描述新动力学，它考虑速度，精力效率和再生刹车的扩大范围。基于新模型，有最小精力的消费的最佳的开车策略被学习，并且这个问题被归结到为交换系统的最佳的控制。用一个数字算法，三阶段的开车策略被结束，在哪个传统的伪海岸阶段再被丢弃，最大的拖拉和刹车不是合适的。最后，CRH上的案例研究被说明。

简介：尽管高分辨率能被电的记载提供，测量电的木头范围是狭窄的并且被限制接近井。地上凿穿表面电的潜在的大小能检测一个足够宽的范围，但是它的分辨率是有限的，特别地为有复杂的油和水分发或复杂结构的水库。在这研究，我们试图精确地由联合地上凿穿表面和crosswell定位3-D水库水和油分发电的潜力。首先，在垂直、水平的方向的油和水的分布被地上凿穿表面和crosswell检测电的潜在的方法，分别地然后测量crosswell潜力结果被用来校准测量地上凿穿表面改进垂直分辨率以便剩余油分发在有三种尺寸的更低的一半空间是坚定的电的潜在的数据。剩余油分发的评估被水库的模拟结果之间的差别的调查有或没有水泛滥获得。有限差别数字模拟结果证明空间剩余油分发能被联合crosswell和地上凿穿表面有效地决定电的潜力。
