Many processes in industry exhibit time-delay in their dynamic behavior. Time-delay is mainly caused by the time required to transport energy, information or mass, but it can be caused by processing time as well. There are also many cases when compensation of measurable disturbance is required. In light of these facts, the goal of this paper is to design predictive algorithm for control of time...

this study has been done with the aim of determining the effect of financial and nonfinancial compensation satisfaction on employee engagement considering mediator role of perceived organizational justice. the research statistical population included eight hundred sixty two isfahan municipality employees. three hundred fourtheen persons were selected as the research sample by stratified random ...

The quantum interest conjecture of Ford and Roman asserts that any negative-energy pulse must necessarily be followed by an over-compensating positive-energy one within a certain maximum time delay. Furthermore, the minimum amount of over-compensation increases with the separation between the pulses. In this paper, we first study the case of a negativeenergy square pulse followed by a positive-...

Optimal tracking control (OTC) for discrete time-delay systems affected by persistent disturbances with quadratic performance indexes is considered. Optimal tracking controller is designed based on a sensitivity approximation approach. By introducing a sensitivity parameter, we transform the original OTC problem into a series of difference equations without time-advance on time-delay terms. The...

BACKGROUND AND PURPOSE The current treatment for femoral fractures in children is mostly operative, which contrasts with treatment of other long bone fractures in children. We analyzed treatment injuries in such patients in Finland in order to identify avoidable injuries. Our other aims were to calculate the incidence of these fractures and to describe the treatment method used. METHODS The P...

Motor dynamics in antagonistic variable stiffness actuator (AVSA) is generally disregarded control system design. This ignorance can lead to an inaccurate model, affecting the performance of closed-loop system. The motor be modeled as input-delay model. In this paper, input time-delay for AVSA first time. a nonlinear function states; thus, tracking challenging task. Specifically, many existing ...

BACKGROUND AND PURPOSE Tibial fractures comprise 10% of all fractures in children. To our knowledge there have been no previous reports of treatment injuries in these fractures. We analyzed compensation claims concerning treatment of these fractures in Finland. We used this information to determine preventable causes of treatment injuries. MATERIAL AND METHODS In Finland, the Patient Insuranc...

In this paper a design of an observer for Lipschitz nonlinear systems in the presence of time-varying delay in outputs measurements is proposed. The structure of the proposed observer is based on the presence of a proportional integral term which permits the compensation of delay in the measurements outputs. The observer gain is a function of the maximum bound of the delay, the parameters of th...
