Metrics of performance for discrete-time descriptor jump linear systems
(ElsevierAmsterdam, 2014-03)
Analytical tools to measure the performance of a control system described by a discrete-time descriptor jump linear system are given. Specifically, a closed-form expression for the steady-state output power as well as a ...
Robust state prediction for descriptor systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2008)
This paper deals with the problem of state prediction for descriptor systems subject to bounded uncertainties. The problem is stated in terms of the optimization of an appropriate quadratic functional. This functional is ...
Handwritten feature descriptor methods applied to fruit classification
(2018-01-01)
Several works have presented distinct ways to compute feature descriptor from different applications and domains. A main issue in Computer Vision systems is how to choose the best descriptor for specific domains. Usually, ...
Texture analysis by multi-resolution fractal descriptors
(ElsevierAmsterdam, 2013-08)
This work proposes a novel texture descriptor based on fractal theory. The method is based on the Bouligand- Minkowski descriptors. We decompose the original image recursively into four equal parts. In each recursion step, ...
H(infinity) filtering for rectangular discrete-time descriptor systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2009)
This paper deals with the H(infinity) recursive estimation problem for general rectangular time-variant descriptor systems in discrete time. Riccati-equation based recursions for filtered and predicted estimates are developed ...
Ground and excited state similarity studies by means of Fukui and dual-descriptor matrices
(Elsevier Science, 2012-10)
This Letter reports a quantitative study of the similarity between the Fukui matrices corresponding to the ground state and those of the first excited state of a molecular system, as well as between the dual-descriptor ...
Genetic divergence among maize hybrids by morphological descriptors
(Instituto Agronômico de Campinas, 2015-06-01)
Two experiments with 25 maize commercial hybrids were carried out in a direct sowing system in Southern Brazil in the harvests of 2009/2010 and 2010/2011. Quantitative descriptors were used with the objective of determining ...
Recursive linear estimation for general discrete-time descriptor systems
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
This paper considers the optimal linear estimates recursion problem for discrete-time linear systems in its more general formulation. The system is allowed to be in descriptor form, rectangular, time-variant, and with the ...
HTS: A new shape descriptor based on Hough Transform
(2013-09-09)
In this paper we propose a novel method for shape analysis called HTS (Hough Transform Statistics), which uses statistics from Hough Transform space in order to characterize the shape of objects in digital images. Experimental ...
