Introduction and purpose: The ability of the elderly to maintain balance during cognitive activity changes. Given the importance of recognizing the nature of the balance disorder among the elderly and the importance of verbal commands in rehabilitating such disorders, the purpose of this study was to investigate the Effectiveness of Dual Task and Focus of Attention Intervention on Balance in El...

Introduction and purpose: Investigating effect of various exercises as the main influencing factor on elderly balance became more popular in the recent years. This research aimed to investigate effect of combined sensory and cognitive training on elderly women health static and dynamic balance. Materials and Methods: 36 healthy elderly women voluntarily participated in this study and their p...

abstract type-ii fuzzy logic has shown its superiority over traditional fuzzy logic when dealing with uncertainty. type-ii fuzzy logic controllers are however newer and more promising approaches that have been recently applied to various fields due to their significant contribution especially when the noise (as an important instance of uncertainty) emerges. during the design of type- i fuz...

Permanent magnet motors have been considered for a variety of applications due to their features such as high power density and high efficiency. One of the issues that should be investigated in the design of these motors is the demagnetization problem. Usually, the demagnetization analysis is carried out in a steady state, while demagnetization effect in dynamic condition is more considerable d...
