Different designs have been presented to achieve high concentration and uniformity for the concentrated photovoltaic (CPV) system. Most of the designs have issues of low efficiency in terms of irradiance uniformity. To this end, we present a design methodology to increase irradiance uniformity over solar cell. The system consists of an eight-fold Fresnel lens as a primary optical element (POE) ...

China’s state-owned enterprises (SOEs) overseen by the central government’s StateOwned Assets Supervision and Administration Commission (SASAC) made net profits of RMB 299 billion during the first half of 2005 and RMB 400 billion in 2004. All nonfinancial SOEs, including those administered by provincial and municipal authorities, earned total profits of RMB 759 billion in 2003, representing 6.5...

The estimation of Linear Time Invariant (LTI) models is a standard procedure in System Identification. Any real-life system will however be nonlinear and time-varying, and the estimated model will converge to the LTI second order equivalent (LTI-SOE) of the true system. In this paper we consider some aspects of this convergence and the distance between the true system and its LTI-SOE. We show t...
