Adaptive threshold generation in robust fault detection using interval models: Time-domain and frequency-domain approaches
(2013-10)
Article
Accés restringit per política de l'editorialIn this paper, robust fault detection is addressed on the basis of evaluating the residual energy that it is compared against worst-case value (threshold) generated considering parametric modeling uncertainty using interval ... -
Adaptive transfer functions: improved multiresolution visualization of medical models
(Springer, 2016-05-14)
Article
Accés obertMedical datasets are continuously increasing in size. Although larger models may be available for certain research purposes, in the common clinical practice the models are usually of up to 512x512x2000 voxels. These ... -
Adaptive us-mrac for disturbance cancellation
(Institution of Electrical Engineers, 1995-01)
Article
Accés obertA variable structure, model reference adaptive control (VS-MRAC) devoted to cancel interferences without the requirement of an auxiliary input is proposed. This method is an improved alternative to the strategies recently ... -
