Reliability and Accuracy of Linear Position Transducers During the Bench Press ...
Montoro-Bombú, Raynier; Costa, Armando; Sousa, Paulo Malico; Pinheiro, Valter; Forte, Pedro; Monteiro, Luis; Ribeiro, Alex S.; Rama, LuisSelecting the right linear position transducer (LPT) for velocity-based training monitoring sometimes presents uncertainties for coaches. Objectives: This study rigorously examined the test-retest reliability of three LPT–Cs using a simultaneous triangulation method of the same device during bench press (BP) and back squat (SQ) exercises performed on a Smith machine. Methods: Forty university students—13 female...
An improved multi-threaded implementation of the MCSFilter optimization algorithm
Monteiro, Luis; Rufino, José; Romanenko, Andrey; Fernandes, Florbela P.The Multistart Coordinate Search Filter (MCSFilter) is an optimization method suitable to find all minimizers of a non convex problem, with any type of constraints. When used in industrial contexts, execution time may be critical, in order to keep production processes within safe and expected bounds. One way to increase performance is through parallelization. In this work, a second parallel version of the MCSFi...
Comparative analysis between different approaches for single-phase PLLs
Monteiro, Luis; Pinto, J. G.; Monteiro, Vítor Duarte Fernandes; Couto, Carlos; Afonso, João L.This paper presents a comparative analysis between two distinct synchronizing circuits, which are usually applied as the core of control algorithms for single-phase power quality applications. One of these synchronizing circuits corresponds to a single-phase Phase-Locked Loop (PLL), implemented in α-β coordinates (αβ-PLL), whereas the other one corresponds to the Enhanced PLL (E-PLL). The major contribution of ...
Study of prevalence, severity and risk factors of periodontal disease in a Port...
Relvas, Marta; López-Jarana, Paula; Monteiro, Luis; Pacheco, José Júlio; Braga, A. C.; Salazar, FilomenaPeriodontal disease is a common worldwide oral inflammation/infection affecting tissues that surround and support teeth. This study aims to evaluate the prevalence, extent and severity of periodontal diseases and its risk factors, according to the most recent periodontal classification, in an adult population of Northern Portugal. This observational study collected data from clinical records of patients who att...
Phenotypic evolution in adrenoleukodystrophy.
Mendes, Paula; Meneses, Isabel; Monteiro, Luis; Coelho, Teresa; Vasconcelos, Cristiana; Lemos, Manuela; Ferreira, Rita; Sá Miranda, Maria ClaraThe X-linked adrenoleukodystrophy (ALD) is a genetic disease, caused by a defect mapped to Xq28. It is characterised by progressive demyelination of the cerebral white matter and adrenal insufficiency. The most important change that occurs is the accumulation of very long chain fatty acids (VLCFAs). The authors describe a patient whom the initial phenotype was Addison disease only (AO). With 21 years old he dev...
