Hybrid systems can switch between many operating modes where each mode is governed by its own characteristic dynamical laws. Mode transitions are triggered by variables crossing specific thresholds (state events), by the lapse of certain time periods (time events), or by external inputs (input events). A simple example of a hybrid system would be a car. The dynamics of the car switch when a gea...

In non-stationary channels, error rates vary considerably. The paper compares Yao’s Adaptive Go-backN (GBN) Automatic-Repeat-Request (ARQ) scheme with Adaptive go-back-N with sliding window mechanism which both estimate the channel state in a simple manner, and adaptively switch their operation mode. The throughput of these schemes is compared in conditions of Additive White Gauss Noise (AWGN) ...

In recent years, Many manufacturing industries for promoting their efficiency have tended to use the automatic manufacturing systems. Expanding automatic systems and to increase their complexity are representing the necessity of studying a proper functional quality and using reliable equipment in such systems more than ever. In this direction, the technique of fault tree analysis (FTA), along w...

Partial Automation (PA) with intelligent support systems has been introduced in industrial machinery and advanced automobiles to reduce the burden of long hours human operation. Under PA, operators perform manual operations (providing actions) that switch automatic/manual mode (mode-switching). Since PA reduces total duration operation, these two action mode-switching can be replicated by imita...

BACKGROUND The efficacy of mode switching to predict atrial fibrillation has been established in the literature. There have been few studies investigating the incidence and clinical implication of mode switch episodes quantified from implantable cardioverter defibrillator and pacemaker interrogation. We sought to investigate the incidence of mode switch recurrence in patients with implantable c...

Software component reuse is deemed as an effective technique for managing the growing software complexity of large systems. Software complexity can also be reduced by partitioning the system behavior into different modes. Such a multi-mode system can change behavior by switching between modes under certain circumstances. Integrating component reuse and the multi-mode approach, we have developed...
