Robust H∞ filtering for networked control systems with markovian jumps and packet dropouts
2014
Published version of an article in the journal: Modeling, Identification and Control. Also available from the publisher at: http://dx.doi.org/10.4173/mic.2014.3.3 Open Access This paper deals with the H∞ filtering problem for uncertain networked control systems. In the study, network-induced delays, limited communication capacity due to signal quantization and packet dropout are all taken into consideration. The finite distributed delays with probability of occurrence in a random way is introduced in the network.The packet dropout is described by a Bernoulli process. The system is modeled as Markovian jumps system with partially known transition probabilities. A full-order filter is designe…
No one ever steps in the same discussion twice: The relationship between identities and meaning
2016
The concept of identification is a relational construct; that is, identities are not static but rather negotiated based on available material and symbolic resources. However, we know relatively little about how identities play a dual role when students collaborate. The aim of this paper is to explore this process through multiple case studies: we aim to explore how identities are enacted and used in making personal sense and understand the content knowledge, while at the same time we are interested in how this process can take a form of renewing process in the sense that the identities enacted are themselves changed, transformed or re-negotiated. Our results show that due to its dual role, …
Identification of New Genetic Clusters in Glioblastoma Multiforme: EGFR Status and ADD3 Losses Influence Prognosis
2020
Glioblastoma multiforme (GB) is one of the most aggressive tumors. Despite continuous efforts to improve its clinical management, there is still no strategy to avoid a rapid and fatal outcome. EGFR amplification is the most characteristic alteration of these tumors. Although effective therapy against it has not yet been found in GB, it may be central to classifying patients. We investigated somatic-copy number alterations (SCNA) by multiplex ligation-dependent probe amplification in a series of 137 GB, together with the detection of EGFRvIII and FISH analysis for EGFR amplification. Publicly available data from 604 patients were used as a validation cohort. We found statistical associations…

The impact of Information Technology on the identification of species and archiviation of taxonomic and floristic data.
2007
In plant taxonomy, classification aims at reconstructing an evolutionary history, usually represented by means of phylogenetic trees. The approach followed by the classification is hierarchical, and rather in coherence with the dichotomies traditionally used for identifying a certain species. But classification and identification are different, since the latter just aims at finding the name of a specimen, eventually in order to get information on it. There are many ways to identify a specimen: to trace it back to its origin, by following the bifurcations of its phylogenetic tree is one possibility, but not always the easiest and quickest one. This theme has been touched during the symposium…
Bòvedas tabicadas: experimental and numerical analysis
2008
A class of thin vaults, the so-called “bovedas tabicadas”, which represent one of the most common Spanish traditional building techniques at the end of XIX century are studied here, treating the relevant analysis problem through a numerical, as well as an experimental, approach. At first the problem is studied by searching for the behaviour of the material effecting suitable experiments. Once the constitutive behaviour of the materials and the structural elements are experimentally characterized, a semi inverse method for the identification of the optimum mechanical parameters to assign to an equivalent homogeneous ideal material through analysis reproducing the executed experimental tests …

Applications of the Alcohol Use Disorders Identification Test (AUDIT) in Distinct Health Areas
2019
Abstract This chapter provides an updated vision of the contexts in which the psychometric viability of the AUDIT has been evaluated during this century. This has permitted the identification of why, where, and how this screening method, as well as its most well-known abridged version (the AUDIT-C), is being used in different socio-sanitary areas. Throughout the chapter, appropriate recommendations are offered for all professionals wishing to use these instruments, while also pointing out potential future research lines.
Numerical methods to compute sentinels for parabolic systems with an application to source terms identification
1994
We apply the method of sentinels to the identification of source terms in parabolic systems. We present two numerical approaches; the first one is based on the solution of an optimal control problem, and the second one is based on the solution of a linear system of equations. In numerical experiments, we compare these approaches in terms of accuracy and computational cost.
Error detecting in inductive inference
1995
Several well-known inductive inference strategies change the actual hypothesis only when they discover that it “provably misclassifies” an example seen so far. This notion is made mathematically precise and its general power is characterized. In spite of its strength it is shown that this approach is not of universal power. Consequently, then hypotheses are considered which “unprovably misclassify” examples and the properties of this approach are studied. Among others it turns out that this type is of the same power as monotonic identification. Then it is shown that universal power can be achieved only when an unbounded number of alternations of these dual types of hypotheses is allowed. Fi…
