In this paper, we study the simultaneous controllability of wave systems in an open domain ${\mathbb R}^d$, $d\in{\mathbb N}^*$. We obtain a partial result on finite co-dimensional space for equations coupled by single control function. use microlocal defect measures and unique continuation property eigenfunctions to prove that appropriate observability inequality holds with varying different s...

Abstract Exoplanets around multiple-star systems are interesting targets for direct detection. However, it is difficult to suppress unwanted light from all stars in a system. For detection of the exoplanets systems, we propose using common-path visible nulling coronagraphs (CP-VNCs). CP-VNCs can diffracted located on central null fringe. In addition, wave front control system installed generate...

According to the inherent characteristics of hydraulic power take-off (PTO) system, output a generator tends be intermittent when wave is random. Therefore, this paper aims improve effective utilization energy and reduce intermittency by constructing topology with two branches transmit electrical energy. Firstly, wave-to-wire (W2W) model system constructed. Secondly, W2W simulated using synovia...
