Analysis of the descriptor Roesser model with the use of the Drazin inverse

open access: yesInternational Journal of Applied Mathematics and Computer Science, 2015
A method of analysis for a class of descriptor 2D discrete-time linear systems described by the Roesser model with a regular pencil is proposed. The method is based on the transformation of the model to a special form with the use of elementary row and ...

On computing least order fault detectors using rational nullspace bases [PDF]

open access: yes, 2003
We propose a numerically reliable computational approach to design least order fault detectors using descriptor system techniques. This approach is based on a new numerically stable algorithm to compute least order rational nullspace bases of rational ...

An ink texture descriptor for nir-imaged medieval documents [PDF]

open access: yes, 2009
In this work we explore the task of authenticating and dating ancient manuscripts by capturing images of pages in nearinfrared (NIR) and modelling and then comparing the ink appearance of segmented text.

Descriptor-free QSAR: effectiveness in screening for putative inhibitors of FGFR1

open access: yes, 2022
The long short-term memory (LSTM) algorithm has provided solutions to the limitations of the descriptors-utilizing QSAR models in drug design. However, the direct application of LSTM remains scarce.
