Application of the Group-Theoretical Method to Physical Problems

Application of the Group-Theoretical Method to Physical Problems

The concept of the theory of continuous groups of transformations has attracted the attention of applied mathematicians and engineers to solve many physical problems in the engineering sciences. Three applications are presented in this paper. The first one is the problem of time-dependent vertical temperature distribution in a stagnant lake. Two cases have been considered for the forms of the w...

Determinants of Physical Activity Behaviors among People Aged 30 to 50 Years: An Application of the Trans-Theoretical Model

Aims: Low mobility is the 4th common cause of human death. The Trans-Theoretical Model (TTM) is a health behavior change theory that describes the process of how people change their behavior. This study was conucted with the aim of investigating the determinants of Physical Activity (PA) behavior based on the TTM in 30-50-year-old individuals. Materials and Methods: In this cross sectional des...
