QoS adaptation is an important process in inter-domain service management, since it can guarantee the correct service provisioning when unexpected events occur. However, in inter-domain environments, the human interference and the manual-based operations hamper the deployment of expeditious mechanisms to adapt the QoS of the services. This paper presents an(More)
BACKGROUND Many scales have been proposed for the brief nutritional assessment of older persons, with the goal of increasing undernutrition detection and the detection of nutritional risk. The Mini-Nutritional Assessment (Guigoz et al., 1994) has been increasingly used worldwide, but its efficacy has been assessed in few countries. OBJECTIVES This study(More)
Virtual private networks (VPNs) are a popular and cost-effective means to build wide-area corporate networks, since they provide bandwidth, privacy and security for a fraction of the cost of private networks. However, establishing VPNs across different domains (inter-domain VPNs) is still a cumbersome task, requiring human- based negotiation between(More)
PURPOSE The reliability and construct validity of three age-adapted-intensity Yo-Yo tests were evaluated in untrained (n = 67) vs. soccer-trained (n = 65) 9- to 16-year-old schoolgirls. METHODS Tests were performed 7 days apart for reliability (9- to 11-year-old: Yo-Yo intermittent recovery level 1 children's test; 12- to 13-yearold: Yo-Yo intermittent(More)
Inter-domain QoS-aware service provisioning is still a complex task due to the Internet heterogeneity. It is necessary to overcome several obstacles in order to achieve a scenario where providers fully interact to satisfy all customer service requirements. Some of these obstacles are service class specification and service composition. This paper presents(More)
Pulmonary artery sarcoma is a rare and highly lethal disease whose clinical findings are often indistinguishable from those of chronic thromboembolic pulmonary hypertension. Partial improvement after thrombolytic therapy has suggested that thromboembolic phenomena may be superimposed on the tumor, but, to date, a well-documented statement of these events(More)
This paper implements and evaluates a multi-criteria approach to select appropriate service providers in a large scale multi-provider environment. This approach uses the Analytic Hierarchy Process (AHP) method in a Peer-to-Peer Service Overlay Network (P2P SON) composed of several service providers in order to select the most suitable one to deliver the(More)
Nocardiosis is an opportunistic infection which occurs mostly in immunocompromised individuals. Pulmonary presentation is the most frequent; however it can affect other parts of the body. Antibiotic treatment is usually prolonged to avoid relapses. The authors present a case report of a patient under prolonged immunosuppressive therapy for psoriatic(More)
Managing a wireless sensor network is not a trivial task. Due to its limitations, such as sensors equipped with low power batteries, it is essential to extend the lifetime of the network. This task becomes harder when dealing with heterogeneous wireless sensor networks, in which sensors have different physical characteristics, such as battery capacity and(More)
