Economical and Accurate Digitally Programmable Dual-Polarity Gain Amplifier

open access: yesActive and Passive Electronic Components, 1995
A digitally programmable, dual-polarity gain amplifier is proposed. It uses total resistance less than those presented earlier. The effect of on-resistance of switches can be fully compensated.

Characterizations of bivariate conic, extreme value, and Archimax copulas

open access: yesDependence Modeling, 2017
Based on a general construction method by means of bivariate ultramodular copulas we construct, for particular settings, special bivariate conic, extreme value, and Archimax copulas. We also show that the sets of copulas obtained in this way are dense in

L-Fuzzy Sets and Isomorphic Lattices: Are All the “New” Results Really New? †

open access: yesMathematics, 2018
We review several generalizations of the concept of fuzzy sets with two- or three-dimensional lattices of truth values and study their relationship. It turns out that, in the two-dimensional case, several of the lattices of truth values considered here ...

A data-driven approach to clinical decision support in tinnitus retraining therapy

open access: yesFrontiers in Neuroinformatics, 2022
BackgroundTinnitus, known as “ringing in the ears”, is a widespread and frequently disabling hearing disorder. No pharmacological treatment exists, but clinical management techniques, such as tinnitus retraining therapy (TRT), prove effective in helping ...

Knowledge-based vision and simple visual machines [PDF]

open access: yes, 1997
The vast majority of work in machine vision emphasizes the representation of perceived objects and events: it is these internal representations that incorporate the 'knowledge' in knowledge-based vision or form the 'models' in model-based vision. In this
