A T-bit/s ATM switching system architecture, called the OPTlMA switch, is proposed. This system is scalable and quasi-non-blocking by virtue of its self-load-balancing mechanism and high-speed interconnection effect. The selfload-balancing mechanism prevents overloading in the switch by automatically checking and balancing the internal load. An experimental 640-Gbitls ATM switching system was d...

Foreign function interfaces are typically organised monolithically, tying together the specification of each foreign function with the mechanism used to make the function available in the host language. This leads to inflexibile systems, where switching from one binding mechanism to another (say from dynamic binding to static code generation) often requires changing tools and rewriting large po...

We consider a robust switching control problem. The controller only observes the evolution of the state process, and thus uses feedback (closed-loop) switching strategies, a nonstandard class of switching controls introduced in this paper. The adverse player (nature) chooses open-loop controls that represent the so-called Knightian uncertainty, i.e., misspecifications of the model. The (half) g...

In modeling a cold standby redundancy allocation problem (RAP) with imperfect switching mechanism, deriving a closed form version of a system reliability is too difficult. A convenient lower bound on system reliability is proposed and this approximation is widely used as a part of objective function for a system reliability maximization problem in the literature. Considering this lower bound do...

maintaining customer interest to repurchase is an important issue in today's competitive market of italian restaurants in tehran. therefore, determining the reasons that caused switching intention in customers, can be leading to arrange marketing purposes. so this research intends to evaluate effect of perceived quality, satiation and satisfaction on switching intention and to examine mode...

In this paper, a new bidirectional buck-boost dc-dc converter with capability of soft switching and zero input current ripple is proposed. The coupled inductor is used in the proposed converter to eliminate the input current ripple. In the proposed converter, zero voltage switching (ZVS) and zero current switching (ZCS) can be obtained for the main and auxiliary switches, respectively. In addit...

This paper proposes a switching adaptive control for trajectory tracking of unmanned aircraft systems. The switching adaptive control method is designed to overcome the wind disturbance and achieve a proper tracking performance for control systems. In the suggested system, the wind disturbance is regarded as a finite set of uncertainties; a controller is designed for each uncertainty, and a per...

This paper presents a novel control method to improve the efficiency of low-voltage DC-DC converters at light loads. Pulse Width Modulation (PWM) converters have poor efficiencies at light loads, while pulse frequency modulation (PFM) control is more efficient for the same cases. Switching losses constitute a major portion of the total power loss at light loads. To decrease the switching losses...

A common method to study the dynamic behavior of macroeconomic variables is using linear time series models; however, they are unable to explain nonlinear behavior of the series. Given the dependency between stock market and derivatives, the behavior of the underlying asset price can be modeled using Markov switching process properties and the economic regime significance. In this paper, a two-...
