The paper presents experimental results on quadratic assignment problem. The “scanning area” method formulated for radioelectronic equipment design is applied. For all more complex tests ours results are better or coincident with the ones known in literature. Conclusion concerning the effectiveness of method are given.

russian language, with regard to its grammar, is a language with its own special complexities, hardly found in other languages. although languages are different from each other, they have some similarities as well. the iranian learner, while learning russian, analyzes the sentences using patterns similar to his/ her native language patterns. occasionally, such native patterns cause the learner ...

positioning, including spatial analysis is that much effect in reducing the cost of creating and launching various activities there. that's why one of the important and effective steps projects are considered. one of the preoccupations of urban planners in designing urban spaces and locate the appropriate service areas and is optimal. the main goal of establishing stations to provide fire ...

multicast routing is one of the most important services in multi radio multi channel (mrmc) wireless mesh networks (wmn). multicast routing performance in wmns could be improved by choosing the best routes and the routes that have minimum interference to reach multicast receivers. in this paper we want to address the multicast routing problem for a given channel assignment in wmns. the channels...

many appealing multicast services such as on-demand tv, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. when multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. designing a good multicast tree to route data packets could enhance the...

it is shown in [1] that the optimal downlink radio resource allocation for non-realtime traffic in cellular cdma/tdma networks can be mapped to a multi-dimensional multiple-choice knapsack problem (mmkp) which is np-hard. in this correspondence we propose a heuristic algorithm with polynomial time complexity for this problem. numerical results indicate significant computational performance impr...

Traffic assignment algorithms are used to determine possible use of paths between origin-destination pairs and predict traffic flow in network links. One of the main deficiencies of ordinary traffic assignment methods is that in most of them one measure (mostly travel time) is usually included in objective function and other effective performance measures in traffic assignment are not considere...

concerning the population growth and urban development, significant growth in the rate of personal car usage has caused more transportation and thus growth in occupying the street areas for parking vehicles. this has caused much transporting problems and traffic. hence concerning the parking issue is crucial in traffic and municipal management.the important issue is the suitable place for the p...
