Descriptor- and Non-Descriptor Controllers in H ∞ Control of Descriptor Systems
IFAC Proceedings Volumes, 2000Abstract In this paper H ∞ control of high index and non-regular linear descriptor systems is addressed. Based on a generalization of the bounded real lemma (BRL) it is shown how the standard, i.e. non-descriptor, H ∞ control problem can be can be generalized to descriptor systems.

Affine invariant shape descriptors: The ICA-Fourier descriptor and the PCA-Fourier descriptor
2008 19th International Conference on Pattern Recognition, 2008In this paper, we propose two new affine invariant shape descriptors, the ICA-Fourier descriptor and the PCA-Fourier descriptor. We tested the descriptors by using them as features for shape based silhouette image retrieval. Experiments on a 1000 silhouette image database show promising retrieval rates of 95.41% and 93.63%, using the ICA-Fourier ...

Despite the number of available chemicals growing exponentially, testing of their toxicological and environmental behavior is often a critical issue and alternative strategies are required. Additionally, there is the need to predict properties of not yet synthesized compounds to reduce the costs of synthesis, selecting only those that have the maximal ...

Theoretical Descriptors of Electrides
The Journal of Physical Chemistry A, 2018Electrides are ionic substances in which the anionic species is stoichiometrically replaced with localized electrons that reside within crystal voids. Originally discovered in 1983, the past decade has seen a sharp rise in the number of known electride materials, most notably the isolation of the first air- and water-stable electride.

Abstract Many crystallographers are aware that estimated standard deviations (e.s.d.’s) of structural parameters routinely calculated by current least-squares refinement programs are unrealistic (a fitting acronym would be u.s.d.’s) and that the actual uncertainties are larger, and sometimes much larger (Taylor & Kennard, 1986 ...
