Tunable active chirped-corrugation waveguide filters [PDF]
A novel tunable semiconductor waveguide reflection filter is proposed and analyzed. The filter is based on spatially selective gain pumping of a chirped-corrugation waveguide.

Active Collaborative Filtering
Collaborative filtering (CF) allows the preferences of multiple users to be pooled to make recommendations regarding unseen products. We consider in this paper the problem of online and interactive CF: given the current ratings associated with a user, what queries (new ratings) would most improve the quality of the recommendations made?

Using the real-time simulator for prototyping power electronics inverter [PDF]
This paper deals with real-time (RT) simulators applied in power electronic applications and implemented in a real inverter. The process of preparing and starting up an active rectifier prototype (with an active filter function), using the real-time OPAL

Optimization of Butterworth and Bessel Filter Parameters with Improved Tree-Seed Algorithm
Filters are electrical circuits or networks that filter out unwanted signals. In these circuits, signals are permeable in a certain frequency range. Attenuation occurs in signals outside this frequency range.

Analysis of Amoeba Active Contours [PDF]
Subject of this paper is the theoretical analysis of structure-adaptive median filter algorithms that approximate curvature-based PDEs for image filtering and segmentation. These so-called morphological amoeba filters are based on a concept introduced by
