BACKGROUND The authors conducted a two-year clinical trial to evaluate the effectiveness of two resin-based composite materials for Class II restorations placed according to two filling techniques. METHODS Twenty-six patients received 105 Class II restorations, which the authors distributed randomly into three groups of 35 each. The resin-based composite(More)
This paper presents an approach to the reconfiguration of radial distribution networks, for both loss reduction and service restoration, using the same metaheuristic tool: the simulated annealing algorithm. Besides the main objective of each problem (minimizing losses or load not supplied) minimization of the total number of switching device operations is(More)
Based on evidence-based dentistry (EBD) being a relatively new concept in dentistry, the attitudes, perceptions and level of awareness of dentists regarding EBD, and perceived barriers to its implementation into daily practice, were comparatively analysed in six countries of the FDI (World Dental Federation-Federation Dentaire Internationale)-European(More)
An increasing number of people reports sleeping problems. In the present paper we describe Somnia: a system designed to support remote couples to fall asleep faster and to enhance their sleep quality. Following a user-centered design process, Somnia was prototyped and evaluated. Qualitative feedback after a two-week user study showed that Somnia succeeded(More)
OBJECTIVE To analyze the impact of model for end-stage liver disease (MELD) allocation policy on survival outcomes after liver transplantation (LT). INTRODUCTION Considering that an ideal system of grafts allocation should also ensure improved survival after transplantation, changes in allocation policies need to be evaluated in different contexts as an(More)
This paper presents views on how quantitative multiple criteria decision-making (MCDM) approaches may be applied to certain aspects of user experience design and evaluation (D&E) methods identification, emphasizing its strengths and weaknesses for this task. Often D&E methods need to be applied in contexts different of those they had been applied before and(More)
This paper presents the VIP Analysis plug-in of Decision Deck 1.1, a platform that hosts different evaluation methods to support decision makers in the collaborative evaluation of alternatives in a multi-criteria and multi-experts setting. VIP Analysis is a tool for aggregation of multicriteria performances by means of an additive value function under(More)
This paper presents the Collaboration Studio (CS) system, its argumentation and data-structuring models and gives some insights for dealing with information divergence. The system allows discussions among a group of participants that includes a coordinator. The working mechanisms implemented within CS are perfectly transparent to the user, hiding(More)
The authors developed an algorithm and a proof-of-concept tool to help business analysts search a pool of hundreds or thousands of services to find the closest ones to their needs when they are composing business processes, even when an exact match does not exist. The authors achieve this by semantically annotating the services with properties from an(More)
