The aim of this study was to determine the effect of weight transfer training on static and dynamic balance of older women. 20 accessible subjects that met our criteria divided randomly into two experimental and control groups. The experimental group trained for 6 weeks, 3 times a week and each session 60 minutes a day. Biodex balance system used for training and testing procedures. Data analys...

 Aims and background: Inappropriate kinetic and kinematic are considered as effective factors in knee injuries especially patellofemoral pain. The aim of this study was to investigate the immediate effect of Mulligan taping on knee dynamic valgus, maximum knee flexion angle, the maximum ground reaction force, time to stabilization and pain in physically active female with patellofemoral pain an...

Objectives: Postural control is the act of maintaining and restoring a better state of balance and proper biomechanics structure in limbs and different parts of the body. Such proper structure exists in two forms namely static and dynamic. Fatigue is one of the factors that affect the postural control and body stability. The purpose of this study was to examine the effect of hip abductor musc...

In the present research, two sets of data were analyzed for the purpose of obtaining the oscillatory derivatives of the sway force and yaw moment with respect to the sway velocity and sway acceleration. The results of the analysis show that the values of the derivatives which were calculated from the dynamic test data are somewhat different from the values of the same derivatives which were cal...

Rapid development of engineering activities expands through a variety of rock engineering processes such as drilling, blasting, mining and mineral processing. These activities require rock dynamic fracture mechanics method to characterize the rock behavior. Dynamic fracture toughness is an important parameter for the analysis of engineering structures under dynamic loading. Several experimental...

The ability to perform rolling contact fatigue (RCF) experiments in wheel–rail material is provided by a new small–scale test rig, manifesting the actual dynamic behaviour of the railway system. In this paper, a multi-body dynamics (MBD) model is proposed, simulating the vibration behaviour of the prescribed rig. The new testing facility is modelled using a three-dimensional model of the vehicl...

In this work dynamic recrystallization behavior of AISI 403 martensitic stainless steel was studied using hot compression tests over temperature range of 900 C -1200 C and strain rate range of 0.001 s-1 - 1 s-1. The obtained flow curves showed that the hot compression behavior of the alloy is controlled by dynamic recrystallization. The flow stress and strain corresponding to the critical, pe...

Dynamic cone penetration (DCP) test is used more in pavement design and construction, and less for subsurface geotechnical investigation and clay core dam. In the present article, evaluating geotechnical parameters of Sanandaj’s clay in the western region of Iran using the DCP test was taken into account. Accordingly, 6 trial pits with maximum depths of 15 m were excavated manually in various s...

This paper introduces a novel area of research to the Image Forensic field; identifying High Dynamic Range (HDR) digital images. We create a test set of images that are a combination of HDR and standard images of similar scenes. We also propose a scheme to isolate fingerprints of the HDR-induced haloing artifact at “strong” edge positions, and present experimental results in extracting suitable...
