Time-effi cient screening of lower extremity biomechanics to identify potential injurious movement patterns is crucial within athletic medicine settings. When considering biomechanical risk factors for anterior cruciate ligament injuries, several screening tests have been used to assess dynamic knee valgus. Current methods involving 3-dimensional motion capture systems are considered gold stand...

Limit cycles, because they are constituted of a periodic succession of states (discrete or continuous) constitute a good manner to store information. From any points of the state space reached after a perturbation or stimulation of the cognitive system storing this information, one can aim to join through a more or less long return trajectory a precise neighbourhood of the asymptotic trajectory...

Using CFD, the paper deals with a simulation of all phenomena related to forced-air duct fitted fan, emphasis on unit aerodynamic resistance and untight air ducts. We created 3-dimentional model system including perforations simulating untightens in order make computation network. Boundary conditions were set calculations made ANSYS Fluent 19.1 programme. The computational results assessed usin...
