In this paper, the robust waveform optimization problem with imperfect clutter prior knowledge is addressed for improving the detection performance of MIMO-OFDM radar based STAP in the complex environment. Robust waveform optimization is needed due to that fact that MEMO radar waveform design is often sensitive to estimation errors in the initial parameter estimates (i.e., some prior information on...
Cyber-physical energy systems, which emerges as the approach for integrating physical layers and control networks, have drawn extensively attention in recent years. Electric load forecasting is believed to be an important issue in CPES for its applications in prices determination and automatic generation control. Conventional deterministic load forecast method have drawbacks to providing information...
A 3-D chirped high-contrast grating hollow-core waveguide (HCG-HW) exhibits highly efficient 2-D (transverse and lateral) light confinement. Compared with step-index ones, laterally chirped HCG-HWs (graded index) can pronouncedly reduce the propagation loss without compromising the lateral index contrast. Simulation results show that a propagation loss as low as 0.04 dB/cm can be achieved...
Abstract--By the research on evaluation index system of entrepreneurial team training mode, we carry on the direct analysis of reasonableness of training mode, so that it can promote the development of entrepreneurial team training mode and improve the competitiveness of the organization. This paper starts at domestic and foreign research status, and analyzes the dynamic mechanism of entrepreneurial...
One of the fundamental problems involving DNA sequences is to find high density segments of certain widths, for example, those regions with intensive guanine and cytosine (GC). Formally, given a sequence, each element of which has a value and a width, the maximum-density segment problem asks for the segment with the maximum density while satisfying minimum and possibly maximum width constraints. While...
As an important part of knowledge management (KM), the KM performance evaluation tries to find out the key factors restraining the enhancement of the enterprises' performance. In this paper, some primary factors of the performance of enterprises KM are analyzed and an index system of KM performance is established by considering some aspects, such as marketing capability, information management, maturity...
