H6-inveter
提出一种新颖的高效率六开关逆变器(H6)拓扑，解决了无变压器单相光伏并网逆变器漏电流问题。 仿真与实验验证了该拓扑具有低共模电压、高质量的并网波形和高效率特征(This paper proposed a novel, high efficiency, transformerless single phase photovoltaic grid-connected inverter with six active switches that alleviate leakage current
issue. This topology embeds two unidirectional freewheel units
into the midpoint of a full bridge inverter, which provide novel freewheel paths and separate battery cells a grid during freewheeling time. )

说明： Recent advances in the relevant technologies of
contemporary wireless sensor nodes has motivated a growth in
the deployment of wireless sensor networks (WSN) for
commercial, non-commercial and research applications. In the
aforementioned applications, it is often prudent to frustrate
unauthorised wireless communications with WSN nodes.

Locally-Laplace-Isometries
发表在 The MIT Talbot 2013 Workshop 的论文 (Locally Laplace Isometries and Fibonacci Primes. this paper shows that there exists a reversible, unique and separable elliptic, Brahmagupta arrow. In this setting, the ability to study positive scalars is essential. Recent interest in partially ultra-positive domains has centered on deriving Pythagoras{Wiles scalars.)
