This paper proposes an online calculation method of theoretical power losses for high-voltage(HV) distribution system based on rapid modeling and data quality analysis in order to improve the timeliness, accuracy and efficiency of the important task. At first the power grid structure model can be rapidly formed according to the basis data library transferred from the original PSD-BPA format file....
Editor’s note: To reduce the manufacturing cost of heterogeneous 3-D integration, the Integrated Fan-Out Wafer-Level Chip-Scale Packaging (InFO WLCSP) is one of the emerging packaging technologies. In this article, the authors propose a cost model for InFO WLCSP, which can be used for analyzing the total test cost with respect to the test configuration and for optimizing the test configuration and...
Rectangular hexahedron sonotrode has remarkable advantage as a platform to realize auxiliary ultrasonic vibration of workpiece with its abundant resonant frequency. However, the three-dimensional coupled vibration characteristics of rectangular hexahedron sonotrode is hard to meet the requirement of ultrasonic assisted micro forming process, which should be made structural optimization for improving...
This paper proposed a novel radial maximum temperature thermal network based on hollow cylinder geometry. By local linear fitting method, the nolinear term in the radial maximum-termperature expression of the hollow cylinder was linearized, therefore, the maximum-temperature expression cou ld be described by the thermal network method. A dynamic compensation unit was used in the thermal network in...
Input-series and output-parallel (ISOP) connected DC-DC converters are suitable for high voltage input and high current output applications by using low voltage rating switches. Cross feedback output current sharing (CFOCS) control can realize the power balance between each module easily and effectively. This paper describes the stability mechanism analysis of the CFOCS control based on small signal-model,...
This article puts forward the third-party guarantee mechanism model with uncertain information. And proved in incomplete information conditions, Guarantee agencies charge premium and reverse collateral will change the profit function and reduce the income of SMEs. It makes partial lower risk SMEs who cannot provide counter-guaranty exit the credit-guarantee market, resulting in the appearance of credit...
The paper focuses on the phenomenon of noun omission in the natural language understanding system. Based on the analysis of the omission in user requirements in natural language form, we will eventually result into the conceptual design requirements or design parameters. Firstly the paper analyze the omitted phenomenon, briefly describe the omission of several types of fixed structure in semantic...
Intrusion Detection is an indispensable component of Network Security. Because exists the problems of the high false positives rate and low detection efficiency in the current intrusion detection system, in this paper, we propose a hybrid intrusion detection model and improve intrusion detection system analyzer, applying the Data fusion and data mining techniques to intrusion detection systems. We...
Electro-Hydrostatic Actuator (EHA) is an integrated system whose performance is related to many disciplines, such as electrics, mechanics, hydraulics and control. In order to achieve the performance optimization, the best way is to balance the multidisciplinary and realize the integrated optimization. This paper focuses on the collaborative design and simulation based on commercial software AMESim...
