OBJECTIVE To study the prevalence of and associated factors for cognitive impairment and dementia in community dwelling Chinese from Singapore. METHODS This study includes Chinese subjects from the Epidemiology of Dementia in Singapore (EDIS) study, aged ≥60 years, who underwent comprehensive examinations, including cognitive screening with the locally(More)
Distributed Event-Based System (DEBS) provides a versatile solution for asynchronously exchanging data in a distributed system, loosely-coupled in space and time. The software architecture of a DEBS is composed of an over-lay network of brokers that are responsible for routing data from producers to consumers. An important issue is the cost (in terms of(More)
The Internet of Things (IoT) is a very dynamic and heterogeneous environment that generates plethora of sensor data, accessible to develop new smart pervasive applications. However, the substantial amount of effort required to collect and disseminate context data with sufficient quality prevents the context consumers to take advantage of the IoT to its full(More)
The informant AD8 has good discriminatory indices in detecting questionable dementia. However, studies on participant AD8 yielded inconsistent results. This study aims to investigate the discriminatory ability of the AD8 in detecting cognitive impairment at a memory clinic by comparing the informant AD8, participant AD8, Montreal Cognitive Assessment(More)
Mobile ad-hoc networks, MANETs, are self-organized and very dynamic systems where processes have no global knowledge of the system. In this paper, we propose a model that characterizes the dynamics of MANETs in the sense that it considers that paths between nodes are dynamically built and the system can have infinitely many processes but the network may(More)
With Mobile Ad hoc Networks (MANETs), communication between mobile users is possible without any infrastructure. MANETs are already a necessary part of wireless systems. Due to arbitrary node arrivals, departures, crashes and movements, network partitioning may arise resulting in a degradation of the service, but not necessarily in its interruption. In this(More)
Contexte et problématique : Ce travail s'inscrit dans les travaux de recherche du projet MARGE de l'équipe ACMES du laboratoire SAMOVAR de Télécom SudParis, et plus particulièrement dans nos travaux en algorithmique répartie pour les systèmes répartis à base d'événements [1, 2] en environnement mobile. Les applications sensibles au contexte à destination(More)
