With the identification of cooperative vehicular communication as an encouraging solution to real time traffic management problems, there has been efforts in evaluating more efficient communication technologies and applications. Field operational tests (FOTs) exist and provide precise evaluation tools but they have limitations. It is impractical to imagine evaluation of large scale city like sc...

Portfolio and risk management problems of power utilities may be modeled by multistage stochastic programs. These models use a set of scenarios and corresponding probabilities to model the multivariate random data process (electrical load, stream flows to hydro units, and fuel and electricity prices). For most practical problems the optimization problem that contains all possible scenarios is t...

Selected waste management scenarios were evaluated with regard to the goals of the Austrian Waste Management Act, taking into account long-term environmental protection and resource conservation as well as costs. Municipal solid waste (MSW) and sewage sludge have been chosen as the system inputs. The scenarios were compared to the status-quo scenario by combining Material Flow Analysis (MFA) an...

experiment was conducted as split plot in a randomized complete block design with three replications in kermanshah to shed lights on economic analysis of deficit irrigation and integrated application of biological and chemical fertilizer son cultivation of medicinal plant borage (borago officinalis l). irrigation tritments include: a) 30% less water than crop requires invegetative, b) inreprodu...

Currently, there is a major concern about the future of nutrient loads discharged into the Baltic Sea from Polish rivers because they are main contributors to its eutrophication. To date, no watershed-scale studies have properly addressed this issue. This paper fills this gap by using a scenario-modeling framework applied in the Reda watershed, a small (482 km²) agricultural coastal area in nor...

In this work, we discuss the diffusion of federated identity management. We base our research on Roger’s diffusion of innovation theory, and derive generic factors influencing the diffusion of federated identity management solutions. To validate our model and investigate specific contributions of parameters in specific usage scenarios, we investigate market success of federated identity managem...
