It is a documented fact that mathematical formulation of physical phenomena in many diverse fields such as electrical engineering, control theory, medicine and even in biology often leads to initial value problems of the form , . In this paper, we propose a one-step numerical scheme that can solve some of these problems. The proposed method compares very well with other known methods. The effic...

We review recent efforts to re-formulate the Einstein equations for fully relativistic numerical simulations. The so-called numerical relativity (computational simulations in general relativity) is a promising research field matching with ongoing astrophysical observations such as gravitational wave astronomy. Many trials for longterm stable and accurate simulations of binary compact objects ha...

Background: The dispersed phase volume fraction plays key role in oil-in-water emulsion stability by different mechanisms like partial flocculation, depletion flocculation and bridging flocculation. Since the mentioned mechanism is affected by emulsifier concentration presented in system, the major aim of this study was to investigate the effect of dispersed phase volume fraction on physical st...

in human beings, the balance control is a result of an integration of physical and psychological factors and people show different reactions when feel anxious or face stability threatened conditions such as standing on an unstable surface. university students, particularly the female ones, are a group of the society who are prone to face anxieties. the current study focused on the effects of an...

purpose ankle sprain is one of the most common injuries among athletes and instability and injury to this joint is responsible for long time loss of physical and recreational activity. also, it can impose high costs to sport teams. prevention of this injury is an important concern of practice and rehabilitation. one way of reducing the possibility of ankle joint injury is using an ankle orthosi...

The aim of the article was to review studies on the tracking of physical activity in all phases of life from childhood to late adulthood. The majority of the studies have been published since 2000. The follow-up time in most studies was short, the median being 9 years. In men, the stability of physical activity was significant but low or moderate during all life phases and also in longterm foll...

Objective Early detection of limited physical activity and nutritional deficiencies in cancer survivors could contribute to early treatment and preservation of quality of life. The aim of this study is to describe the association of physical condition and nutritional status with fatigue and quality of life in oncological out-patients. Methods Data in this descriptive study was collected on bi...

In this paper, we have studied on the solutions of modied KdV equation andalso on the stability of them. We use the tanh method for this investigationand given solutions are good-behavior. The solution is shock wave and can beused in the physical investigations
