Fractional-Order System Identification of Viscoelastic Behavior: A Frequency Domain Based Experimental Study
2020
In this work, the fractional-order modeling of viscoelastic behavior is investigated based on measurement data in the frequency domain. For the results of two different test setups we apply existing parameter estimation algorithms designed for fractional-order transfer functions. These algorithms require a priori knowledge of the system structure including the commensurate order of differentiation. An iterative procedure is used to evaluate the influence of the unknown structure. The measured polymer samples show a viscoelastic stress response. We can show that integer-order models are not capable of capturing this behavior. For a set of predefined structures, the best obtained fractional-o…

A Humanoid Social Robot Based Approach for Indoor Environment Quality Monitoring and Well-Being Improvement
2020
The indoor environmental quality (IEQ) monitoring inside buildings where people spend most of their time is essential for ensuring their well-being. Traditional approaches based on Building Automation and Control Systems consider buildings equipped with many different sensors. Unfortunately, the sensors are not always placed for taking the measurements at the right positions. Besides, users could feel a negative perception due to continuous supervision. The present work proposes an approach based on a social humanoid robot that monitors indoor environmental quality. It friendly interacts with occupants providing appropriate suggestions. Particularly, the social robot has been endowed with c…
Buckling and post-buckling analysis of cracked stiffened panels via an X-Ritz method
2019
Abstract A multi-domain eXtended Ritz formulation, called X-Ritz, for the analysis of buckling and post-buckling of stiffened panels with cracks is presented. The theoretical framework is based on the First-order Shear Deformation Theory and accounts for von Karman's geometric nonlinearities. The structure is modeled as assembly of plate elements. Penalty techniques are used to fulfill the continuity condition along the edges of contiguous elements and to satisfy essential boundary conditions requirements. The use of an extended set of approximating functions allows to model through-the-thickness cracks and to capture the crack opening and tip singular fields as well as the structural behav…
VARIABLE SELECTION FOR NOISY DATA APPLIED IN PROTEOMICS
2014
International audience; The paper proposes a variable selection method for pro-teomics. It aims at selecting, among a set of proteins, those (named biomarkers) which enable to discriminate between two groups of individuals (healthy and pathological). To this end, data is available for a cohort of individuals: the biological state and a measurement of concentrations for a list of proteins. The proposed approach is based on a Bayesian hierarchical model for the dependencies between biological and instrumental variables. The optimal selection function minimizes the Bayesian risk, that is to say the selected set of variables maximizes the posterior probability. The two main contributions are: (…
Conditional Versus Joint Probability Assessments
1984
AbstractThe assessment of conditional and / or joint probabilities of events that constitute scenarios is necessary for sound planning, forecasting, and decision making. The assessment process is complex and subtle, and various difficulties are encountered in the elicitation of such probabilities such as, implicit violations ofthe probability calculus and some meaningfjilness conditions. The necessary and sufficient as well as meaningfulness conditions that the elicited information on conditional and joint probabilities must satisfy are evaluated against actual assessments empirically. A high frequency of violation of these conditions was observed in assessing both conditional and joint pro…

Family Postmemory of the People of Silesia
 The author suggests a possible use of postmemory to analyse the contemporary family memory of the people of Silesia. Their memoirs about WW2 (such as working for the Wehrmacht, the Red Army invading Silesia, working in labour camps, nationality verification, displacements to Germany, and deportations to Siberia) bear signs of latent memory which is rarely revealed even to the next of kin. Present mainly within the family circle, within the local society, and among friends, these memoirs integrated Silesians and made them a unique community that considers itself a stigmatized minority. This contributed to mythologizing and stereotyping the who…
Introducing postqualitative inquiry in sport and exercise psychology
2021
In recent years, qualitative research has gained popularity and legitimacy in sport and exercise psychology. However, this scientific discipline has not yet paid attention to postqualitative inquiry (PQI), despite the possibilities it offers for producing different knowledge and producing knowledge differently. The present article is the first attempt to rectify this lack of attention by offering a brief and partial sketch of PQI in the context of sport and exercise psychology. To start with, three of the basic propositions that enable PQI are described. These are: adopt a posthumanist view of ontology and the subject; engage with poststructuralism (necessarily) and new materialism (possibl…
Leucocyte Rheology at Baseline and after Activation in Post-Phlebitic Syndrome
1999
Objective: To evaluate leucocyte rheology, expressed as leucocyte filtration, polymorphonuclear leucocyte (PMN) membrane fluidity and cytosolic Ca2+ concentration in subjects with post-phlebitic leg syndrome (PPS). Methods: In 22 subjects with PPS we determined leucocyte filtration [unfractionated, mononuclear (MN) and PMN cells], employing the St George Filtrometer, PMN membrane fluidity using the fluorescent probe 1-[4-(trimethylamino)phenyl]-6-phenyl-1,3,5-hexatriene (TMA-DPH) and PMN cytosolic Ca2+ concentration using the fluorescent probe Fura 2-AM. Subsequently we determined the same PMN parameters after in vitro activation with 4-phorbol 12-myristate 13-acetate (PMA) and N-formyl-met…
Incidence de l’endophtalmie aiguë postopératoire après chirurgie de la cataracte par phacoémulsification et injection intracamérulaire d’antibiotique…
2016
National audience; Introduction La chirurgie de la cataracte est l’intervention la plus fréquente dans le monde. Parmi ses complications, l’endophtalmie aiguë postopératoire (EAPO) est une infection intraoculaire sévère, qui peut conduire à la cécité. Les objectifs étaient de déterminer l’incidence de l’EAPO après chirurgie de la cataracte par phacoémulsification en France de 2005 à 2014 et d’analyser l’association entre injection intracamérulaire d’antibiotique (IICA) et EAPO. Méthodes Tous les patients hospitalisés pour une chirurgie de la cataracte en France entre le 1er janvier 2005 et le 31 décembre 2014 ont été identifiés dans le programme de médicalisation des systèmes d’information …
