The paper proposes a novel validity evaluation method, Improved Feature Selective Validation, in order to evaluate the uncertainty analysis results in Electromagnetic Compatibility simulation. By comparing with the questionnaire results, it is shown that the proposed method can provide more accurate evaluation than a previous method called Mean Equivalent Area Method.
Data to be compared, such as transients, which is naturally segmented presents a particular set of problems for data comparison and validation in general. Two of the most challenging problems are (a) how to segment and weight the data so that the aspects that dominate the visual assessment also dominate the computed results; (b) how to ensure that the original data is not ‘engineered’ to give a biased...
Three-phase high voltage power standard has been established at National Institute of Metrology, China. The power standard based on high accuracy three-phase power source, which adopts real-time feedback control technology to achieve excellent stability and accuracy output characteristics. Power/energy measurements can be made at three voltage levers, 10kV, 35kV, 110kV, and current up to 1000A. In...
As an important part of credibility evaluation, uncertainty analysis has been taken into consideration in Electromagnetic Compatibility (EMC) simulation. Frequently, the quantitative validation of the uncertainty analysis results is performed by comparing a group of results of Mont Carlo Method (MCM) and reliable references. In this case, the multiple data sets comparison method needs to be developed...
To better decide the sequence of ammunition sort choice when one object is attacked by several kinds of ammunitions, that is the ammunition target matching problem for artillery field. In this paper, first depicting ammunition damage effect and target anti-damage effect and constructing the ammunition target matching index system. Then, rough set theory was applied to reduce the index system and determine...
The uncertainty of technology innovation results in high risk. It is very important to innovation success that enterprise systematically manage risks in the technology innovation process. The main task of risk management is to identify and evaluate all risks. In the article, the source of innovation risk is concluded technology risk, market risk, organizing risk and environmental risk. On the basis...
