This article presents a new method of risk propagation among associated elements. On the basis of coloured Petri nets, a new class called propagation nets is defined. This class provides a formal model of a risk propagation. The proposed method allows for model relations between nodes forming the network structure. Additionally, it takes into account the bidirectional relations between componen...

Abstract: As a new approach slow intelligence system is proposed to manage the network problem. The architecture and special feature of SIS is to improve the result and get the feasible solution for the netwo...

An adaptive transmission protocol is described and evaluated for use in wireless communication networks that employ dynamic spectrum assignment. The protocol interacts with a spectrum assignment system to select the modulation format and symbol transmission rate for each session. The power is adjusted during the initial part of each session, and code-rate adaptation is employed to compensate fo...

In a previous paper by Dunham and Rake (1948) the successful propagation of Donovania granulomati8 on artificial media, after adaptation, was described. Since that publication the strain has been maintained for additional passages on the media containing equal parts of 3 per cent agar in beef heart infusion broth and modified Levinthal's stock broth. The present communication will describe the ...

We introduce the FronTier-Lite software package and its adaptation to the TSTT geometry and mesh entity data interface. This package is extracted from the original front tracking code for general purpose scientific and engineering applications. The package contains a static interface library and a dynamic front propagation library. It can be used in research of different scientific problems. We...

This article first summarises some basic problems in the field of calculation of radiowaves propagation for land mobile services. New approach to the solution of this problem using artificial neural networks is proposed here. Two examined networks are shortly introduced at first. The adaptation of these networks to the solved problem is shown. Practical results of the usage of these networks ar...

How language teachers talk is a key factor in organizing and facilitating learning specifically in language classrooms where the medium of instruction is also the subject matter. This study aimed to examine the extent and ways of teacher talk adaptation to students’ proficiency levels in the Iranian EFL context. Two EFL teachers who were teaching three different proficiency levels were observed...

This paper, while focused primarily on the narrative transformation of Sadeq Chubak’s Tangsir from novel to film adaptation, offers a general survey of adaptation history in Iran and also investigates the nature of Iranian adaptation from both foreign and domestic sources. Drawing on Gerard Genette’s theories of Narratology, especially his notion of hypertextuality, transpragma...

An adapti e finite-element method for the analysis ofwa eguiding structures based on the error at each inner edge of the meshis presented. The error indicator is based on the fulfillment of thedi ergence Maxwell equations. The adaptation of the unknowns to thefield distribution allows better accuracy in the propagation constant,maintaining a low computational cost. 2000 John...
