conclusions an intervention based on the theory of planned behavior was effective in improving the foot care in diabetic patients. results the two groups showed no significant difference in terms of demographics or in the mean scores of other variables before the intervention (p > 0.05). after the intervention, a significant increase was observed in the mean scores of attitudes, and foot care p...

The present work applies a control architecture proposed by W.T. Powers to several problems in robotics, and suggests that it may have wide practical applicability. The architecture is called (Hierarchical) Perceptual Control Theory, or HPCT, and was proposed by Powers as a possible organisation for living control systems.

A representation of the limit occupational measures set of a control system in terms of the vector function defining the system’s dynamics is established. Applications in averaging of singularly perturbed control systems are demonstrated.

In this paper, we propose an idea which can solve the complexity of the overlapping situation observed in control system of living things. We introduce an another element between controlled object and control law. This newly introduced element is named as Implicit Control Law and decided by interaction of the controlled object , the control law and the field. Furthermore, the Implicit Control L...

In this chapter we present a brief description of 1 robust control. We first motivate the use of the 1norm and then show how it is used in formulating a control problem with the objective of minimizing the effect of unknown by bounded disturbances. This leads to formulation of the 1 optimal control problem, for which we present a solution using the Scaled-Q method. We then address the problem o...

We investigate the dependence of the gauge couplings on the dilaton field in string effective theories at the one–loop level. First we resolve the discrepancies between statements based on symmetry considerations and explicit calculations in string effective theories on this subject. A calculation of the relevant one–loop scattering amplitudes in string theory gives us further information and a...
