2. WIND EFFECTS ON FOUNDATIONS OF SILOS AND LIGHT STRUCTURES: SOLUTION BY USE OF STEEL PILES IN DIABASIC SOIL
ABSTRACT Wind solicitations generate horizontal, tensile, and compressive stresses on building foundations. In empty light structures, such as agricultural greenhouses and, in the specific case of silos and elevated structures such as metal water tanks, the consideration of these loads becomes important because the lack of the weight component due to the sto

3. Prediction of 3D ground reaction forces during gait based on accelerometer data
Abstract Introduction The aim of this study was to predict 3D ground reaction force signals based on accelerometer data during gait, using a feed-forward neural network (MLP). Methods Seventeen healthy subjects were instructed to walk at a self-selected speed with a 3D accelerometer attached to the distal and anterior part of the shank. A force plate was

4. Lower limb ice application alters ground reaction force during gait initiation
BACKGROUND: Cryotherapy is a widely used technique in physical therapy clinics and sports. However, the effects of cryotherapy on dynamic neuromuscular control are incompletely explained. OBJECTIVES: To evaluate the effects of cryotherapy applied to the calf, ankle and sole of the foot in healthy young adults on ground reaction forces during gait initiation

5. Ground reaction forces during level ground walking with body weight unloading
Background: Partial body weight support (BWS) systems have been broadly used with treadmills as a strategy for gait training of individuals with gait impairments. Considering that we usually walk on level ground and that BWS is achieved by altering the load on the plantar surface of the foot, it would be important to investigate some ground reaction force (

6. Vertical force calibration of smart force platform using artificial neural networks
INTRODUCTION: The human body may interact with the structures and these interactions are developed through the application of contact forces, for instance due to walking movement. A structure may undergo changes in the dynamic behaviour when subjected to loads and human bodies. The aim of this paper is to propose a methodology using Artificial Neural Network

7. Isokinetic analysis of ankle and ground reaction forces in runners and triathletes
OBJECTIVE: To analyze and compare the vertical component of ground reaction forces and isokinetic muscle parameters for plantar flexion and dorsiflexion of the ankle between long-distance runners, triathletes, and nonathletes. METHODS: Seventy-five males with a mean age of 30.26 (±6.5) years were divided into three groups: a triathlete group (n=26), a long-

9. Estudo biomecânico do processo de aquisição da marcha independente em bebês
A aquisição da marcha independente é um importante marco desenvolvimental e considerada o maior desafio biomecânico a ser vencido pela criança. Nos primeiros 5-6 meses do andar independente, rápidas mudanças acontecem em todos os parâmetros da marcha. Um aspecto que se destaca é o grau de variabilidade apresentado pelo padrão de marcha nessa fase,

12. Efect of non-affected lower limb constraint and seat height on the motor performance of hemiparetics post stroke during sit-to-stand / Efeito da restrição do membro inferior não-afetado e a altura do assento sobre o desempenho motor de hemiparéticos durante o movimento de sentado para de pé
Hemiparesis following stroke reduces the ability to use the involved lower extremity during the sit-to-stand (STS) transfer, thus affecting the performance. This study investigated in hemiparetic subjects the combined effects of the non-affected lower limb (NA) constraints by supporting it on a step and the seat height for the weight-bearing on the affected
