Sky condition is a matter of interest for public and weather predictors as part of weather analyses. In this study, we apply a method that uses total solar radiation and other meteorological data recorded by an automatic station for deriving an estimation of the sky condition. The impetus of this work is the intention of the Catalan Meteorological Service (SMC) to provide the public with real-t...

Fractional sky cover amounts retrieved from sky imagery are overestimated significantly at times due to occurrences of “whitening” near the sun, and near the horizon for low sun, in the images. This phenomenon occurs due to forward scattering of visible light by aerosols and haze, and the intensity range limitations of the detectors of the cameras used to record the sky images. Our results sugg...

Network Management (NM) has been in some way an activity apart from any other carried on the networks. Monitoring networks and systems resources independently from how users and applications are using them, has proven to be an inadequate approach since in most of the situations it’s impossible to trace the relationship between network or systems faults and the applications affected by them. Fur...

In this research, we propose an architectural solution to integrate the video voice over IP (V2oIP) services in campus environment network and tested over LAN and WAN. Voice over IP (VoIP) technology has become a discussion issue for this time being. Today, the deployment of this technology on an organization truly can give a great financial benefit over traditional telephony. Therefore, this s...

1 This work was supported by DARPA NMS program Abstract A minimum cost routing admits an arriving request on the minimum cost route if this minimum cost does not exceed the cost of the request, and rejects the request otherwise. Minimum cost routing strategies naturally arise as a result of optimization of the network performance or incorporating Quality of Service (QoS) requirements into the a...

In this work, we study the problem of extended source emission high resolution map-making, which is tackled as an inverse problem. Therefore, an unsupervised Bayesian framework is proposed for estimating sky maps and all the related hyperparameters. For the forward problem, a detailed physical model is introduced to describe different instrument effects like: optical transfer function, pointing...
