An improved autofocus method is presented based on minimum-entropy criterion for inverse synthetic aperture radar imaging. The phase-error corrections are initialized by dominant scatter algorithm, and an iterative method is derived to minimize the image entropy. A local quadratic curve is constructed to gradually approach the extremun of the image entropy function, though minimizing the image entropy,...
Carcinoembryonic antigen-related cell adhesion molecule 1 (CEACAM1) is a broadly-expressed immunoglobulin-like cell adhesion molecule with a wide range of biological functions to regulate cell signaling. The present article mainly focuses on the role of CEACAM1 as a therapeutic target in lung diseases and discusses the potential of therapeutic strategies targeting CEACAM1. The article overviews the...
In this paper we propose a multipath routing protocol that considers energy saving and wireless interference. We design the linking cost function that considers node remaining energy and number of hops to the destination node. Two paths are established between source and destination nodes, by using the path discovery process that finds the next hop node which minimize the linking cost. In the proposed...
For the control target of capturing maximum power for variable speed wind turbine when the wind speed is below the rated wind speed, a switching “optimal” tracking controller of the generator angular velocity is designed. First, the generator optimal angular velocity is identified by using dynamic fuzzy neural network. Then a generator angular velocity optimal tracking controller is designed by using...
Compensation arithmetic based on system identification was brought out. Via getting the standard import signal and distortion export signal through the standard calibration device of electrostatic high-voltage potential, the time domain mathematic model and waveform compensation have been studied by system identification arithmetic. Transfer function model was identified by the least square method...
