In this paper, packet loss probability performance in cell-based and packet-based switches with finite Input Queues (IQ) and iLPF scheduling algorithm are analysed. This algorithm has been proposed as a practical scheduling algorithm to achieve 100% throughput in cell-based switches. The scheduling algorithm is implemented in three cases: cellbased (CB-iLPF) switching, packet-based (PB-iLPF) sw...

In this half-day tutorial, we present the current state-of-theart in optical networks. We begin by discussing the various optical devices used in optical networks. Then, we present wavelength-routed networks, which is currently the dominant architecture for optical networks. We discuss wavelength allocation policies, calculation of call blocking probabilities, and network optimization technique...

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...

This paper presents developing an analytical model for flux switching motors. The motor is a class of variable reluctance motors that has two windings on stator; a field winding and an armature winding. Due to saliency of both stator and rotor poles, accurate modeling is difficult which arises from the nonlinear behavior of the machine. This paper presents a simple model which is able to predic...

The large amount of computation necessary for obtaining time optimal solution for moving a manipulator on specified path has made it impossible to introduce an on line time optimal control algorithm. Most of this computational burden is due to calculation of switching points. In this paper a learning algorithm is proposed for finding the switching points. The method, which can be used for both ...

Although gold is no longer a central cornerstone of the international monetary and financial system, it still attracts considerable attention from researchers and investors. Nowadays, many investors manage their risk with valuable assets such as gold. This paper examines the dynamic relationships between gold and stock markets in the Tehran Stock Exchange. We have applied the Markov switching m...

In this paper a new Linear Matrix Inequality (LMI) based switching controller for multiple Bottleneck packet switching Network has been considered. The main goal is to illustrate the effects of the Switching Control methodology on the congestion control problem of the packet switching Networks with dynamically varying parameters such as Link capacity and time delays. The congestion dynamic for ...

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...
