Tennis playing is associated to psychomotor speed in older drivers
Marmeleira, José; Melo, Filipe; Tlemcani, Mouhaydine; Fernandes, JorgeThe study investigated the association of tennis playing and running with the psychomotor speed of older drivers. Thirty-six active male drivers ( M age = 63.2 yr.) participated. A battery of four on-the road driving tests was performed by tennis players, runners, and a control group. Measures of simple and choice reaction time, movement time, and response time were collected under singleand dual-task condition...
Electromagnetic and acoustic coupling during mechanical action in porous media ...
Silva, Hugo Gonçalves; Graça, M.P.F.; Monteiro, J.H.; Bezzeghoud, Mourad; Rosa, R.N.; Mendiratta, S.K.; Tlemçani, MouhaydineElectromagnetic and acoustic coupling (EAC) during mechanical action, was theoretically predicted to occur in porous media [1] and was recently validated experimentally [2]. In fact, the exchange of acoustic waves to electromagnetic emissions is commonly referred in the literature as seismo-electromagnetic phenomena and is engaging a large number of geophysical groups on its study [3]. The reason for this inte...
Analysis of a Non-Iterative Algorithm for the Amplitude and Phase Difference Es...
Janeiro, Fernando M.; Ramos, Pedro M.; Tlemçani, Mouhaydine; Serra, A. C.In this paper, a non-iterative algorithm for amplitude and phase difference estimation of two acquired sinewaves is presented and analyzed. The method is based on the least-squares fitting of ellipses where the common signal frequency is eliminated from the algorithm.
