Overlay networks are expected to be a promising technology for the realization of QoS (Quality of Service) control. Overlay networks have recently attracted considerable attention due to the following advantages: a new service can be developed in a short duration and it can be started with a low cost. The definition and necessity of the overlay network is described, and the classification of va...

The aim of this study is prospecting of iron and manganese in the Balvard 1:100000 sheet which is situated in Sanandaj - Sirjan structural zone utilizing Index Overlay and Fuzzy Logic methods in the GIS. In this study, the layers for integration, alterations, geological, geophysical, geochemical and structural data based on stream sediments, airborne magnetometeric and remote sensing studies. B...

Egypt currently has a high reliance on wind energy, as it only accounts for 12% of the total 20% electricity produced by renewable sources. Due to availability necessary resources and sites establish energy at Egypt's level, is give priority increase dependence it. To do this, develop model determining regions that are suitable locating farms, taking into account number variables, in order make...

Abstract. Overlay applications are popular as they provide high-level functionality by masking the intrinsic complexity of the underlay network. However, overlays rely on the underlay to provide them with basic connectivity. Therefore, the intrinsic features of the underlay network determine the efficiency of the overlay. Accordingly, studying the interdependency of the overlay and underlay net...

Solid waste is one of the leading environmental problems affecting human lives. Selecting a landfill where disposed complicated issue that related to many factors and regulations. In this study, optimal sanitary site for An-Najaf city was assessed using GIS weight criteria method. Eight appropriate were selected, which are: urban area, rivers, roads, soil types, elevation, wind, slope, archaeol...

Coloured overlays and coloured lenses can both increase reading speed, but when they do their colour is not necessarily the same, suggesting that the beneficial effects of a coloured filter might depend upon the area of the visual field that it colours. We investigated the effects of overlays on reading speed and varied the size of the overlay and the colour of the surround. Children who had be...

Overlay networks have emerged as a powerful and flexible platform for developing new disruptive network applications. The attractive characteristics of overlay networks such as planetary-scale distributions, user-level flexibility (e.g. overlay routing) and manageability bring to overlay fault diagnosis new challenges, which include inaccessible underlying network information, incomplete and in...

Application-layer multicast (ALM) protocols differ in, among other aspects, the topology of the underlying overlay network (e.g., tree, mesh or ring). Therefore, comparing the performance of ALM overlay networks is an important step towards assessing the inherent advantages and/or limitations of each overlay network topology. In particular, ring-based ALM overlay networks have the advantages of...

Service specific overlays are overlay networks build and setup for a single service. Since different services need different types of overlays, the setup process is pretty different. Current approaches normally allow a customer to send in an overlay specification into the overlay provisioning system (mainly centralized). In our approach, we use pattern-based management in order to run the proce...

OBJECTIVE To evaluate the diagnostic performance of an automated analysis tool for the assessment of prostate cancer based on multiparametric magnetic resonance imaging (mpMRI) of the prostate. METHODS A fully automated analysis tool was used for a retrospective analysis of mpMRI sets (T2-weighted, T1-weighted dynamic contrast-enhanced, and diffusion-weighted sequences). The software provided...
