a shortest path problem is a practical issue in networks for real-world situations. this paper addresses the fuzzy shortest path (fsp) problem to obtain the best fuzzy path among fuzzy paths sets. for this purpose, a new efficient algorithm is introduced based on a new definition of ideal fuzzy sets (ifss) in order to determine the fuzzy shortest path. moreover, this algorithm is developed for ...

It was shown in [l] and [2] that ‘he flows in open networks of 9 /M/l queues with a single class of customers obe;r the so-called ‘loop criterion’: In equilibrium a flow on a link of such a network is Poisson if and only if the link is not part of a loop. In [3] that criterion was shown to apply to networks of ./M/s queues, i.e., to Jackson networks (see [4]). It was also shown in [3] that this...

the main objective in classification of the nmr spectra of cancerous and healthy tissue , with high number of features is the prerequisites of the minimum number of samples. therefore the use of conventional classifier on this type of the data is not recommended. in the current work, different structures of the artificial neural networks (ann) were tried on classification of different cancerous...

porosity is one of the most important properties for comprehensive studies of hydrocarbon reservoirs. for determination of porosity in a rock, that is the ratio of volume of voids to the total volume of the rock, there are two conventional methods: in the first method, direct measurement of porosity is carried out by testing drilling cores. in the second method, porosity is determined indirectl...

This paper explores quantitative evaluation criteria for service and potentials of new service from the transportation viewpoint. For this purpose, we analyze transport networks of railway, subway, and waterbus, and have revealed the following implications: (1) efficiency criterion proposed by Latora [7, 8] and centrality criterion in the complex network literature can be applied as quantitativ...

This paper presents a novel criterion to study the stability of multilateral teleoperation systems based on passivity. Such systems (modelled as n -port networks) have recently found interesting applications in cooperative haptic teleoperation and haptic-assisted training. The criterion provides researchers with an analytical, closed-form, necessary and sufficient condition useful for both anal...

A novel one-to-all broadcasting scheme, based on an information theoretic decomposition criterion [1], is proposed for arbitrary interconnection networks. The scheme is applicable to both single-port and half-duplex modes of message passing communication. Evidence based on empirical studies indicates the suitability of the scheme for achieving one-to all broadcasting bounds for various types of...

Boolean networks with canalizing functions are used to model gene regulatory networks. In order to learn how such networks may behave under evolutionary forces, we simulate the evolution of a single Boolean network by means of an adaptive walk, which allows us to explore the fitness landscape. Mutations change the connections and the functions of the nodes. Our fitness criterion is the robustne...
