For traditional coverage method, local adaptive weighted search is adopted for subspace reconstruction of e-logistics information, which requires significant iterative computations and leads to large coverage errors and unsatisfactory results. This paper proposes a secure dynamic covering algorithm for e-logistics information based on the basis of directional clustering for the envelope of optimization solution vectors. A data network distribution model of e-logistics information on a cloud computing platform is constructed to extract features of e-logistics information and to construct time series of information flows. The directional clustering algorithm for the envelope of optimization solution vectors is introduced to schedule features of e-logistics information. The experimental results show that the proposed algorithm has higher coverage rate, smaller error, and increases performance of e-logistics information transmission and higher application value on a cloud computing platform. © 2017, IGI Global.

A control method of DFIG wind power system is discussed in this paper. Since the large rotational inertia of the wind turbine, and the low speed variation of it, the speed of wind turbine can be seen as constant in a short interval. By measuring the EMF of rotor, control the rotor side inverter injecting the current into rotor with proper phase and frequency, the power and the reactive power of the machine can be controlled. Control equation and block are given. Simulation and experimental result verify the rightness of the method. © 2016, Xi'an High Voltage Apparatus Research Institute Co., Ltd. All right reserved.

This paper introduces the research and design of a light moisture tester. In the coal quality analysis field, moisture test most of the use of infrared heating pipe heating or drying box to measure, low heating rates, nitrogen through a single mode, before heating furnace uniform nitrogen filled with test conditions and have the test conditions, the same way caused by nitrogen, nitrogen waste. Based on this study, the heating pipe comprises an infrared tube into a light tube, the heating rate is improved; the general nitrogen control size flow switching mode using 2.5min before the experiment, large flow quick heating furnace filled with nitrogen, achieved through experimental conditions drying nitrogen, open a small flow, keep the atmosphere. The improved design of a light moisture meter analysis of water air drying method precision test, analysis of water air drying method accuracy experiments, 6 water - air drying method of precision experiment, 6 water - air drying method accuracy experiments, analysis of water through nitrogen drying method precision experiment, analysis of water. Nitrogen drying method accuracy experiments, ¢ 6 full water through nitrogen drying method precision experiment, ¢ 6 full water through nitrogen drying method accuracy experiments, results in line with national standard test, repeatability. © (2014) Trans Tech Publications, Switzerland.
