Tension leg platform is a compliant structure with vertical moorings and added buoyancy force. In this paper, effective parameters on experimental modeling of TLPs have been investigat. experimental modeling with correct scale factor has been done in Sharif University of Technology marine engineering laboratory test basin. deep water simulation capability were discussed and finally the model, l...
the incremental sheet metal forming (ismf) process is a new and flexible method that is well suited for small batch production or prototyping. this paper studies the use of the finite element method in the incremental forming process of aa1050 sheets to investigate the influence of tool diameter, vertical step size, and friction coefficient on forming force, spring-back, and thickness distribut...
Mechanography is an innovative method to evaluate lower-limb dynamic muscle function. This technique is generally performed on force platforms that measure only the vertical component of ground reaction force (GRF). The underlying assumption is that medio-lateral and antero-posterior forces do not contribute significantly to the GRF in jumping and rising tests. The goal of this study was to est...
Objective: Every person is required to walk and stand for long periods of time during daily activities, especially at work, as a result of which ground reaction force to the parts and joints is very high, and these forces sometimes reach several times the body weight in the foot and the ankle foot can have devastating effects. Various studies have suggested different methods and factors for red...

Objective Foot ulcer is one of the main challenges of diabetic patients influencing their abilities to stand and walk. Various methods have been suggested to decrease the loads applied to the foot in this group of patients; most methods were not deemed successful and could only be used temporarily. Rocker shoes are recommended for foot ulcer treatment. Based on the available literature, it is s...
Introduction: Abnormal pressure during daily activities, including walking, is known as a risk factor in knee joint degeneration in knee amputees. The aim of this research was to analyze ground reaction force (GRF) and sample entropy in below-the-knee amputees. Methods: This study was a descriptive-cross-sectional type, and 20 people with below-knee amputations of the right leg (TT group) and ...
damages due to northridge and kobe earthquakes were expressive of considerable effects of vertical components of earthquakes compared to the horizontal ones. on the other hand, thin steel plate shear wall is one of the newest resistant systems which until now it`s behavior haven’t been investigated under vertical component of earthquake. therefore, in this article, effects of vertical component...
Objective: Unstable shoes have been recommended to osteoarthritis patients in order to reduce walking injuries. The aim of this study was to test the effect of unstable shoe on biomechanical selected variables related to injury during stanse phase of running. Materials & Methods: Twenty five healthy young male students available men (21±2.27years) participated in this study. Subjects were as...
The steady-state structure of a disc with a corona is analyzed when the vertical component of the gravitational force due to the self-gravity of the disc is considered. For the energy exchange between the disc and the corona, we assume a fraction f of the dissipated energy inside the accretion disc is transported to the corona via the magnetic tubes. Analytical solutions corresponding to a pres...
