Dual boundary-element method: Simple error estimator and adaptivity
Portela, A.This paper is concerned with the effective numerical implementation of the adaptive dual boundary-element method (DBEM), for two-dimensional potential problems. Two boundary integral equations, which are the potential and the flux equations, are applied for collocation along regular and degenerate boundaries, leading always to a single-region analysis. Taking advantage on the use of non-conforming parametric bo...

Bettiol, Heloisa; Sabbag Filho, D.; Simões, V.M.F.; Haeffner, Leris Salete Bonfanti; Barbieri, Marco Antonio; Silva, Alessandra Analu Moreira daObesity is one of the rising public health problems characterized as a risk factor for many chronic diseases in adulthood. Early life events such as intrauterine growth restriction, as well as life style, are associated with an increased prevalence of this disease. The present study was performed to determine if intrauterine growth restriction interacts with overweight at primary school age to affect body mass ...

Barbosa, Tiago M.; Lima, F.; Portela, A.; Novais, D.; Machado, L.; Colaço, P.; Gonçalves, P.; Fernades, R.J.; Vilas-Boas, J.P.The purpose of the study was to analyse relationships between total energy expenditure (Etot), energy cost (EC), intra-cycle variation of the horizontal velocity of displacement of centre of mass (dv) and mean swimming velocity (v). 17 Portuguese elite swimmers (4 at Freestyle, 5 at Backstroke, 4 at Breaststroke and 4 at Butterfly) were submitted to an incremental set of nx200-m swims. Bioenergetical and biomec...
