Modified Propagator Method for 2-Dimensional DOA Estimation in Monostatic MIMO Radar with L-Shaped Array
Authors: Li Xin , Xu Ding Jie , Wang Xiao Meng
Published: November 2013

A modified propagator method based on L-shaped array for 2-Dimensional (2-D) direction of arrival (DOA) estimation in monostatic MIMO radar is proposed. A cross-correlation matrix, which can eliminate the influence of noise, is constructed by the received data from the two orthogonal uniform linear arrays (ULAs) at x-axis and z-axis. Then the matrix can be utilized to estimate signal subspace of 2-D DOA through propagator method. At last, the elevation and azimuth angles of the 2-D DOA is automatically paired by the complex eigenvalues of a low-order complex matrix. The 2-D DOA estimation performance of the proposed method is better than conventional propagator method and ESPRIT algorithm. Simulation results verify the effectiveness of the proposed method.
A Fast Algorithm for Motion and Disparity Estimation Based on the Reference Directions of Neighboring Macroblocks
Authors: Kong Xiang Jun , Zhao Yan , Fan Qian , Wang Shi Gang , Chen He Xin
Published: November 2013

As for JMVC (Joint Multi-view Video Coding), when executing motion and disparity estimation simultaneously, the implicit correlation of reference directions between current and neighboring macroblocks is neglected, and this will lead to useless searching. To reduce this redundancy, we propose an estimation algorithm which sets search ranges properly by exploiting the mentioned correlation. The proposed algorithm first gets the reference directions of macroblocks in the left, top and top right direction of current macroblock, and compares them with current reference direction, then sets search ranges by the comparison results, executes motion and disparity estimation in the new ranges at last. Experimental results show that the proposed algorithm can save 28.98%- 46.30% of coding time without degradation of coding quality comparing to JMVC.

This The integrated power system (IPS) to be used in future ships will be a big leap in the building of ship power platforms, representing the prospective direction of in the development of ship power systems. A centralized control console with PLC(Programmable Logic Control) and touch screen has been designed for the propulsion subsystem of the vessel integrated power system. The centralized control console is mainly used to monitor the operations of the propulsion motor and propulsion inverter and to make remote control communications with the propulsion display and control console of energy management. This paper has made a detailed description of its hardware, software and communication, and given full account of the PLC program as well as the process of the start-up, speed regulation and shutdown performed by the propulsion subsystem under local or remote control. The site tests prove that the designed centralized control console can effectively monitor the running conditions of the propulsion subsystem and improve the digitalization, intelligent capability, stability and reliability of the vessel integrated power system, which will be of reference value to the research on ship automatic management and long-distance monitoring.

An optimal multivatiable looper control system based on decoupling strategy has been developed for hot strip finishing mills. Based on the dynamic configuration of the coupling system, we can get the status space expression of the coupling loopers system. Through the tools of Matlab we make out of the transfer function of looper system. Based on Decouping-Inbariable character theory and the transfer function of looper system we gain the transfer function of the decoupling net. By using the Simulink toolbox of the Matlab language, the simulation results have shown that, after decoupled, the loopers control system performance gets much better.

Published: November 2013

In this paper the finite-time stability (FST) problem of continuous-time linear singular systems (CTLSS) is considered. The main results provided are a sufficient condition of FTS for CTLSS and a sufficient condition of robust FTS for uncertain CTLSS. Such sufficient conditions in the LMI formalism are attained for finite-time stability; this gives the opportunity of fitting the finite time stability problem in the general framework of the linear matrix inequality (LMI) approach. In this context an example is provided to demonstrate the application of the proposed method for CTLSS finite-time stability problem.
