today, one of the new technologies in the modern era is vehicular ad-hoc network which has takenenormous attention in the recent years. because of rapid topology changing and frequent disconnectionmakes it difficult to design an efficient routing protocol for routing data between vehicles, called v2v orvehicle to vehicle communication and vehicle to roadside infrastructure, called v2i. designin...

in this paper we develop a new approach for land leveling in order to improve the topology of a large area for irrigation or civil projects. the objective in proposed model is to minimize the total volume of cutting so that technical requirements of land leveling such as suitable slope and standard ratio of cutting to filling and maximum penstock point’s height are considered. we develop a warp...

the aim of this paper is to introduce the concepts of fuzzy upper and fuzzy lower almost continuous, weakly continuous and almost weakly continuous multifunctions. several characterizations and properties of these multifunctions along with their mutual relationships are established in $l$-fuzzy topological spaces

Abstract In recent years, with the development of space science and technology deepening exploration, a new type institution variable topology, its flexibility to adapt environment diversity tasks, has become an important direction multi-purpose highly integrated complex institutions in our country. Therefore, it is very study dynamic problems this kind flexible topology mechanism explore metho...

on a hypergroupoid one can define a topology such that the hyperoperationis pseudocontinuous or continuous. in this paper we extend thisconcepts to the fuzzy case. we give a connection between the classical and thefuzzy (pseudo)continuous hyperoperations.

Population geneticists have shown that the effects of local extinction and recolonization on selectively neutral genetic diversity are sensitive to the number of individuals that migrate between groups. Here, we employ a spatially explicit metapopulation model to investigate the extent to which the effects of local extinction on selectively neutral cultural diversity and change are sensitive to...

In this paper‎, ‎we introduce a new model of point free topology‎ ‎for point-set topology‎. ‎We study the basic concepts in this‎ ‎structure and will find that it is naturally close to point-set‎ ‎topology‎.‎

GENI is evolving to provide a promising environment in which to do experimental research in the resilience and survivability of future networks, by allowing programmable control over topology and mechanism, while providing the scale and global reach needed to conduct network experiments far beyond the capabilities of a conventional testbed. We will use GENI in general, and the GpENI infrastruct...

The technique of diversity coding was introduced to provide fast restoration against link failures in communication networks. We have recently devised algorithms to incorporate diversity coding into networks with arbitrary topology, so that restoration is achieved very fast, in an almost hitless manner, while spare capacity requirements are competitive with the alternative state-of-the-art rest...

In the present study, a novel compact antenna system for diversity/MIMO application is proposed for WLAN (5.8 GHz) band with good isolation between the two input ports. The novelty of the proposed MIMO antenna system is, though the resonators are physically separated by a distance of 0.029λ (λ is the free space wavelength at 5.8 GHz) equal to the thickness of the substrate (1.524 mm) used for t...
