Optimal sizing of C-type passive filters under non-sinusoidal conditions [PDF]
, 2014 In the literature, much attention has been focused on power system harmonics. One of its important effects is degradation of the load power factor. In this article, a C-type filter is used for reducing harmonic distortion, improving system performance ...

Journal of Logic and Analysis, 2022 We introduce a notion of integration defined from filters over families of finite sets. This procedure corresponds to determining the average value of functions whose range lies in any algebraic structure in which finite averages make sense. The most relevant scenario involves algebraic structures that extend the field of rational numbers; hence, it ...

Novel Deep Level Image State Ensemble Enhancement Method for M87 Imaging
Applied Sciences, 2020 Standard spatial domain filters fail to adequately denoise and enhance the contrast of an image. These filters have drawbacks like oversmoothing, diminished texture, and lack of generative capabilities.

An Electrically Programmable Split-Electrode Charge-Coupled Transversal Filter (EPSEF) [PDF]
, 1979 A CCD split-electrode transversal filter (EPSEF) with analog controlled tap weights is described. The programmable tap weighting utilizes a novel analog multiplier for sampled data, based on charge profiling underneath a resistive gate structure.

Estimating the Service Life of Activated Carbon Filters for Air Purification
Eurasian Chemico-Technological Journal, 2019 It is very important to be able to predict the breakthrough time of gas mask filters under real life circumstances. This article describes the use of a very simple predictive equation, the Wheeler-Jonas equation, that yields excellent predictions but ...

Journal of High Energy Physics, 2022 Abstract We propose a new mechanism to simultaneously explain the observed dark matter abundance and the baryon asymmetry of the Universe. The mechanism is based on the Filtered Dark Matter scenario, where dark matter particles acquire a large mass during a first-order phase transition.
