In this paper we propose a new approximate method for calculating the probability of point-to-group blocking in multi-stage switching networks with unicast and multicast connections. The results of analytical calculations of the probability of blocking are compared with the results of discrete events simulations of the switching network with multicast and unicast connections. The present analyt...

Using analytical calculations as well as computer simulations, we show that antiferromagnets can be switched on a time scale of picoseconds using THz laser pulses only. This all-optically triggered switching mechanism rests on the coordinated dynamics of the two interacting sublattices with an inertial character. We calculate the resonance frequencies in the nonlinear regime, the orbits, and es...

This paper uses recent results on continuous-time finite-horizon optimal switching problems with negative switching costs to prove the existence of a saddle point in an optimal stopping (Dynkin) game. Sufficient conditions for the game’s value to be continuous with respect to the time horizon are obtained using recent results on norm estimates for doubly reflected backward stochastic differenti...

Abstruct-This paper proposes a transformer assisted PWM zero voltage switching Neutral-Point-Clamped (NPC) inverter. With the assistance of a transformer assisted small rating lossless auxiliary circuit, the main switches work with zero voltage switching without suffering from any voltage/current spikes, under simple explicit control. The technique allows for higher operating frequency and bett...

Standard choice theory assumes choice to be independent of the point of reference. Based on a number of studies which challenge this assumption, Tversky and Kahneman have proposed a reference-dependent model which captures the in ̄uence of reference points on individual choice. If choice is reference-dependent, switching the reference point so that it is ®rst dominated by x and then by y increas...

This paper investigates the asymmetric effects of monetary policy on economic growth over business cycles in Iran. Estimating the models using the Hamilton (1989) Markov-switching model and by employing the data for 1960-2012, the results well identify two regimes characterized as expansion and recession. Moreover, the results show that an expansionary monetary policy has a positive and statist...

The data acquisition systems of the next generation High Energy Physics experiments at the Large Hadron Collider (LHC) at CERN will rely on high-speed point-to-point links and switching networks for their higher level trigger and event building systems. This thesis provides a detailed evaluation of the DS-Link and switch technology, which is based on the IEEE 1355 standard for Heterogeneous Int...

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...
