Le fil contient des donnees qui decrivent collectivement des etats et des relations de tâches interreliees d'un processus. Des metadonnees du document electronique sont modifiees de facon a refleter le changement de l'etat du fil. Les metadonnees modifiees sont transmises via une operation de messagerie electronique du processus dans le but de mettre a jour le changement d'etat du fil.

The metadata comprises at least information on the relevance between the data units. When a first data set is to be synchronized, metadata associated with at least one initial data unit of the first data set is retrieved. Next, a second data set, which according to at least one metadata element comprises a data unit of maximum relevance to the initial data unit, is selected for synchronization.

The aim is to find out whether a schema-aware binary XML format is better suited to this area than generic compression applied to regular XML. We begin by limiting the potential areas of improvement through considering the features of the binary format, and then proceed to measure effects in the identified areas to determine whether a binary format would be effective.

We describe on the evolutionary steps of the mobile service platform that has been used to field different mobile service concepts in varying business domains. The platform was developed to solve issues of rapid deployment in different field force applications for data gathering and task management. In this report we focus on the changes needed when the platform was used to develop a mobile service for fleet management and automatic data gathering in the road-maintenance domain 1 .
Abstract WMP62: Remote Home Monitoring of Risk Factors After Stroke or TIA to Improve Secondary Prevention - A Pilot Study
Stroke, 2018
Background: Up to 90% of strokes could be prevented by effective treatment of the risk factors. H... more Background: Up to 90% of strokes could be prevented by effective treatment of the risk factors. However, there are major problems with the implementation of prevention. For example, only 40% of patients taking medication have blood pressure (BP) at treatment goals and 60% of patients with atrial fibrillation (AF) use anti-coagulant medication. Hypothesis: Remote home monitoring of risk factors after minor stroke or TIA may lead to better control of risk factors by increasing measurements and patient awareness and uncovering undetected risk factors. This pilot study investigates the feasibility of home monitoring of risk factors after minor stroke or TIA. Methods and Patients: Patients (n=30, mean age 57 yrs, range 34-79, 37% females) with recent minor stroke or TIA were supplied with a remote home monitoring system at discharge. The system comprised of a cloud backend for data storage and processing, patient user interface (UI), and wireless BP meter and light-weight EKG device with...

The variety of mobile workstations, handheld devices, and smart phones, which nomadic users use to access data services in the Internet, increases at growing rate. The outcome is new demands for adaptability of data services. Agent technology is one of the software solutions that may be used to fulfill the demand of "anytime-anywhere-anyhow" access to data services. The research project Monads addresses some of the fundamental challenges in supporting nomadic applications: adaptability to available computing and communication resources that vary in tempo-spatial space and short-term (1-30 minutes) predictions of available resources. In addition to adaptability and predictions, efficient agent communication in wireless environments is a mandatory prerequisite.

However, it can be optimized without breaking compatibility with Java RMI specification, and with minimal changes to existing software in the network hosts. This paper analyzes the reasons for the poor performance of Java RMI and outlines a solution based on mediator technology. A prototype has been implemented, which improves performance by a factor of three.
