In hazardous environments where direct human operation of machinery is not possible, such as in a nuclear power plant (NPP), teleoperation may be utilized to complete tasks safely. However, because are time consuming, complex, highly difficult, and need performed with incomplete information, they increase the operator’s cognitive load, which can affect efficiency operator well completeness task...

A orthogonal decomposition of a general wideband space-time multipath channel is derived assuming antenna arrays at both the transmitter and receiver. Knowledge of channel state information at the transmitter is used to decompose the channel. This decomposition serves as a framework for eeciently managing the degrees of freedom in the space-time channel to trade-oo diversity and throughput. Sig...

In this paper, we shall solve a long-standing open problem: Is it possible that the convergence rate of the Lions’ Robin-Robin nonoverlapping domain decomposition(DD) method is independent of the mesh size h? We shall design a two-parameter Robin-Robin domain decomposition method. It is shown that the new DD method is optimal, which means the convergence rate is independent of the mesh size h. ...
