A simulation model for the interconnected local area networks (LAN's) is presented in this report. The interconnected networks consist of token ring, fiber distributed data interface (FOOl) network and carrier sense multiple access with collision detection (CSMNCO) network. In the interconnected networks, the local users on the token ring send intraor inter-network packets. The inter-network pa...

We propose a method to assist the user in the interpretation of the best Bayesian network model induced from data. The method consists in extracting relevant features from the model (e.g. edges, directed paths and Markov blankets) and, then, assessing the confidence in them by studying multiple locally optimal models of the data. We prove that our approach to confidence estimation is asymptotic...

the alborz mountains, as a folded and faulting region, is the northern region of crust shortening in iran. dominant mechanism (harvard, 2002) of alborz earthquakes is left-lateral strick-slip paralleled to the range. east alborz is one of the active regions that plays a significant role in the tectonics of its neighbors like south casbin basin. regarding the geological maps of the area, the fau...

The traÆc of LAN on large distributed workstation system for educational use has the high-load and high-trangiency. We developed an event-driven simulationmodel for analysis of such a high-loaded network. It has detailed models of multi-layer protocols, applications and user behavior model. In this paper a method to apply this model to multi-segment networks is discussed. Routing tables of netw...

edge detection and edge enhancement techniques play an essential role in interpreting potential field data. this paper describes the application of various edge detection techniques to gravity data in order to delineate the edges of subsurface structures. the edge detection methods comprise analytic signal, total horizontal derivative (thdr), theta angle, tilt angle, hyperbolic of tilt angle (h...

nowadays, the use of intelligent control systems to reduce human error is one of the most popularresearch fields. design and implementation of such controllers requires to actual knowledge of theenvironment conditions. traffic lights as one of the inputs of intelligent control systems are significant.usually the traffic lights have the various physical structure. also, generally in image proces...

In this modeling study, we show the combined e ects of gap junctions and GABAergic synapses on the synchronous ring in networks of fast-spiking (FS) interneurons. We found analytically that two identical electrically coupled FS interneurons re synchronously at arbitrary ring frequencies, whereas an FS neuron pair coupled through GABAergic synapses show asynchronous ring. Accordingly, an FS neur...

In this paper, a new local-world evolving network model including triad formation mechanism is proposed and studied. Analytical expressions for degree distribution and clustering coefficient are derived using continuum theory. It is shown that the degree distribution transfers from exponential to power-law scaling, and the clustering coefficient is tunable with known parameters. Finally, the nu...
