Data is a valuable resource. The proper use of high-quality data can help make better predictions, analysis and decisions. Poor-quality data is detrimental to data analytics. Data from different sources may provide the same entities, but different identities. This becomes a concern particularly when large-scale heterogeneous data from multiple sources are integrated for other purposes. This paper...
This paper presents an analysis of the performance of circuit breakers (CBs) using direct digital sampling and the wavelet transform applied to antenna signals obtained from the arc created during the switching process. Some researches have shown that arcing produces impulsive radio-frequency radiation. Therefore, from timing analysis of the received and recorded impulses, the switching times of circuit...
Many proposed efficient statistical analysis methods in EMC are limited due to the dimensionality problem; when the number of random variables becomes large the methods can become less efficient than using the established Monte Carlo method. In this paper the univariate and bivariate dimension reduction methods are examined for their applicability and efficiency for statistical EMC analysis. The performance...
Cable separation rules to prevent crosstalk between different cable categories are in use for over five decades. The rules have been developed in the analogue era and when equipment was not fulfilling any, or maybe some, electromagnetic interference standard. This has changed but the rules are still in use. The technical rationale is unknown, so simulations and measurements have been performed to...
This paper examines experimental and simulation techniques for quantifying the statistical variation in coupling within an enclosure populated with circuit boards. The performance of equivalent conductive sheets for modelling and/or experiments is compared with circuit board effects to investigate whether simple equivalent models are valid.
