Recent studies have pointed out the benefits of using Silicon Carbide (SiC) devices in photo-voltaic power conversion. In Particular, SiC Power MOSFET technology has greatly advanced over the last years and has presently reached sufficient maturity t

Sparse regression problems, where it is usually assumed that there are many variables and that the effects of a large subset of variables are negligible, have become increasingly important. This paper describes the construction of hierarchical pri

朱荣探测车首先配备了全极化火星探测车穿透雷达(FP-RoPeR)系统，旨在绘制地下精细结构并发现潜在的地下水冰。但是，与以往轨道雷达探测水冰不同的是，当电磁波通过粗糙界面传播时，FP-RoPeR信号会受到感应场旋转(IFR)的影响。因此，在本文中，我们评估了粗糙界面的IFR对FP-RoPeR数据的圆极化比(CPR)响应的影响，这是水冰探测的重要参数。理论计算和数值验证表明，深度、粗糙界面数和相对介电常数是影响IFR效果的三个重要参数;对于FP-RoPeR系统来说，深度比其他两个因素更重要。浅层区
