Shadow and ordering effects in fibrous electret filters
Journal of Aerosol Science, 1992Abstract In this paper “layer” model of a fibrous filter is presented and results of numerical calculation of filtration efficiency for electret filter are shown. They are compared with prediction obtained from the constant single cell efficiency concept. Effect of a filter structure on filtration efficiency is discussed.

Fully Active and Minimal Shadow Bandpass Filter
2018 International Conference on Engineering, Applied Sciences, and Technology (ICEAST), 2018A new topology of shadow bandpass filters is presented in this paper. The proposed circuit employs the active building block of three voltage differencing transconductance amplifiers (VDTA) along with two grounded capacitors. This results in an additional attractive feature of being fully active and minimal component-count. Practical realization of the

Application of shadowing Filter in Weather Predictability
Journal of Information and Computing Science, 2018The physical meaning of the Ikeda model is analyzed. The influence of the parameters in the model on the state of the solution is discussed. The change process of the solution when the parameters are taken from different values is described, and the sensitivity of the solution to the initial value is studied.The tail filter is used ...

Shadow Stereo, Image Filtering, and Constraint Propagation
2005It is agreed that stilus tablets are very important documentary sources, however they are the most difficult to decipher. The difficulties in deciphering them is due to the rough surface of the tablets, the low brightness contrast of the incisions, the dense wood-grain lines, and the badly stained and pitted nature of the tablets.
