This paper has a double purpose. In the first part of the paper we give an overview of different aspects of graph theory which can be applied in communication engineering, not trying to present immediate results to be applied neither a complete survey of results, but to give a flavor of how graph theory can help research in optical networks. The second part of this paper is a detailed example o...

Minimal cost networks are presented when SONET UPSR and BLSR networks are deployed over a WDM fiber ring. The primary cost is the number of SONET ADMs, and a secondary cost is the number of wavelengths. The networks have been designed assuming a nonstatistical traffic model, and guarantees no blocking of traffic. Three network architectures are given that have low ADM costs. It is shown that ne...

با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...

This paper presents an adaptive distributed multimedia streaming server architecture (ADMS) which explicitly controls the serverlayout. It consists of four types of streaming server components, which all provide dedicated services in an arbitrary number of instances on an arbitrary number of server hosts. Vagabond2 is used as the underlying middleware for component adaptation. It is shown, how ...

The grooming factor C of a WDM optical network is the number of connections that can share the bandwidth of each wavelength and the process of grouping the requests that will share each wavelength is called traffic grooming. The goal of traffic grooming is either to reduce the transmission cost by reducing the number of wavelengths or to reduce the hardware cost by reducing the number of Add-Dr...

Large-eddy simulation (LES) with actuator models has become the state-of-the-art numerical tool to study complex interaction between atmospheric boundary layer (ABL) and wind turbines. In this paper, a new evaluation of disk (ADMs) for LES turbine flows is presented. Several details implementation such are evaluated based on test case studied experimentally. contrast other cases used in previou...

the aim of this research paper is the introduction of a novel mathematical approach to improvethe accuracy of the results of air pollution dispersion models based on the calibration of input backgroundconcentrations. using the dunkirk area of the city of nottingham in the uk as a case study, an air pollutionmodel in adms-roads was created for developing the mathematical approach. the iterative ...

Suppose that several parties jointly possess a pure multipartite state, |ψ〉. Using local operations on their respective systems and classical communication (i.e. LOCC), it may be possible for the parties to transform deterministically |ψ〉 into another joint state |φ〉. In the bipartite case, the Nielsen majorization theorem gives the necessary and sufficient conditions for this process of entang...
