We consider a piecewise-deterministic queueing (PDQ) model to study traffic queues due to stochastic capacity fluctuations in transportation facilities. The saturation rate (capacity) of the PDQ model switches between a finite set of values (modes) according to a Markov chain. The inflow to the PDQ is controlled by a state-feedback policy. The main results of this article are stability conditio...

This paper describes the passive Qswitch, based on polymer and organic dye BDN, of a pulsed Nd:YAG laser. Pulses of 27ns duration and peak power of 1.7MW for initial transmission of Q-switch 18.4% 0 T = have been obtained. We have obtained Q-switching efficiency of 77% for train of pulses of 31 and 76.2% 0 T = at the pump energy of 98J. We have also obtained the dependency of laser pulse charac...

Internet Service Providers (ISPs) must interconnect in order to realize the network externality benefits of being able to reach all users. Market power determines whether and how much one provider pays another for interconnection. Recently, antitrust authorities have expressed concern about the potential abuse of market power with respect to network interconnection in the scope of the Internet....

whether for the delay in payment of debt resulting from civil liability can be demand late payment damages? in answering this question, answer of some of lawyers is positive. they believed that late payment damages is accrued to debt resulting from civil liability. because, these creditors are more deserving of protection. also, the word of debt in article 522 of code civil procedure is absolut...

today, e-commerce has considerable portion in commercial businesses, and it has been developing. one of the most important steps in e-commerce is e-payment that has been done through different tools such as e-banking, and e-cheques. in this type of electronic transactions, there are always different worries both for payers and payees due to untruthfulness. for example, amount modifying, date mo...

mobile commerce is whatever electronic transfer or transaction via a mobile modem through a mobile net in which the true value or advance payment is done for goods, services or information. a mobile payment system should be beneficial for all related persons. for a payment system to be a successful system, end-user, seller, exporter and operators should see a additional value in it. end-user pr...

modeling and simulation of communication circuits at high frequency are important challenges ahead in the design and construction of these circuits. knowing the fact that the lumped element model is not valid at high frequency, distributed analysis is presented based on active and passive transmission lines theory. in this paper, a lossy transmission line model of traveling wave switch (twsw) i...
