Automated Analysis in Feature Modelling and Product Configuration

The automated analysis of feature models is one of the thriving topics of research in the software product line and variability management communities that has attracted more attention in the last years. A recent literature review reported that more than 30 analysis operations have been identi ed and di erent analysis mechanisms have been proposed. Product con guration is a well established research eld with more than 30 years of successful applications in di erent industrial domains. Our hypothesis, that is not really new, is that these two independent areas of research have interesting synergies that have not been fully explored. To try to explore the potential synergies systematically, in this paper we provide a rapid review to bring together these previously disparate streams of work. We de ne a set of research questions and give a preliminary answer to some of them. We conclude that there are many research opportunities in the synergy of these independent areas.Ministerio de Ciencia e Innovación TIN2009- 07366Junta de Andalucía TIC-590

Constraint solving in uncertain and dynamic environments - a survey

International audienceThis article follows a tutorial, given by the authors on dynamic constraint solving at CP 2003 (Ninth International Conference on Principles and Practice of Constraint Programming) in Kinsale, Ireland. It aims at offering an overview of the main approaches and techniques that have been proposed in the domain of constraint satisfaction to deal with uncertain and dynamic environments

Troubles d'usage d'alcool et facteurs associés en population générale au Bénin en 2022

International audienceIntroductionLes troubles associés à la consommation de substances psychoactives sont les comorbidités les plus importantes et les plus fréquentes chez les patients atteints de maladie mentale. L'alcool est la substance la plus couramment consommée parmi les substances psychoactives. La consommation d'alcool affecte non seulement l'individu, mais aussi la société dans son ensemble, avec pour conséquences l'altération de la santé, la mort prématurée et le déclin social et économique. Cette étude vise à déterminer la prévalence des troubles d'usage de l'alcool (TUA) ainsi que leurs facteurs associés en population générale au Bénin en 2022.MéthodesIl s'agissait d'une étude transversale portant sur les personnes âgées d'au moins 18 ans et résidents dans la commune de Lalo du département du Couffo en 2022. L’échantillonnage était aléatoire à trois degrés. Les personnes enquêtées étaient interrogées à l'aide d'un questionnaire composite comprenant des données socio-démographiques, le « Timeline Followback » (TLFB), le « Mini International Neuropsychiatric Interview (MINI) ».RésultatsL’échantillon composé de 435 personnes était majoritairement constitué d'hommes (n=241; 55,4 %). L’âge moyen des participants était de 38,05±13,83 ans. La prévalence de la consommation actuelle d'alcool était de 88,7 %. La prévalence du TUA était de 8,7 % (n=38). Le TUA est significativement associé au fait d’être un homme (RR=3,56 ; IC95%= [1,60-7,91] ; p=0,001). Plus le nombre de jours de consommation d'alcool au cours des sept derniers jours augmentait, la prévalence du TUA était plus élevée (x²=53,59 ; p=0,000). Les participants qui ont consommé plus de 6 verres d'alcool au cours des 7 derniers jours étaient plus à risque de présenter un TUA (RR=11,28 ; IC95%=[6,54-19,46] ; p<0,000).ConclusionLa consommation d'alcool et les troubles liés à la consommation de boissons alcoolisées étaient courants dans la population générale du Bénin. Une consommation régulière de boissons alcoolisées est un facteur de risque de trouble d'usage de l'alcool

HLA genetic diversity in Hungarians and Hungarian Gypsies: complementary differentiation patterns and demographic signals revealed by HLA-A, -B and -DRB1 in Central Europe

Systematic analyses of human leukocyte antigen (HLA) profiles in different populations may increase the efficiency of bone marrow donor selection and help reconstructing human peopling history. We typed HLA-A, -B, and -DRB1 allele groups in two bone marrow donor cohorts of 2402 Hungarians and 186 Hungarian Gypsies and compared them with several Central-European, Spanish Gypsy, and Indian populations. Our results indicate that different European Gypsy populations share a common origin but diverged genetically as a consequence of founder effect and rapid genetic drift, whereas other European populations are related genetically in relation to geography. This study also suggests that while HLA-A accurately depicts the effects of genetic drift, HLA-B, and -DRB1 conserve more signatures of ancient population relationships, as a result of balancing selection

Model-Based Reconfiguration

. Knowledge-based configuration is both a successful application domain for AI techniques and and an active research area. An open issue in many practical domains is that of reconfiguration, typically exhibited by legacy systems that are to be extended, upgraded or simply altered. Standard configuration techniques are not necessarily suited to this task. We discuss the use of a diagnosis approach to reconfiguration. We present the differing application and representation requirements, develop a representation that is suitable for expressing the information about the required and configurable functionalities from the diagnosis point of view, present an example and discuss our experiences. 1. Introduction The automated configuration of technical systems is a successful application area for knowledge-based techniques. Initially, configuration research followed the mainstream of expert system research with the use of rule-based expert systems for configuration purposes (McD82), and rule-..
