Algorithmic Differentiation for Cloud Schemes
2019
<p>Numerical models in atmospheric sciences do not only need to approximate the flow equations on a suitable computational grid, they also need to include subgrid effects of many non-resolved physical processes. Among others, the formation and evolution of cloud particles is an example of such subgrid processes. Moreover, to date there is no universal mathematical description of a cloud, hence many cloud schemes were proposed and these schemes typically contain several uncertain parameters. In this study, we propose the use of algorithmic differentiation (AD) as a method to identify parameters within the cloud scheme, to which the output of the cloud scheme is most sensitive.…
A Theoretical Study of the Wet Removal of Atmospheric Pollutants. Part III: The Uptake, Redistribution, and Deposition of (NH4)2SO4Particles by a Con…

Abstract Our model for the scavenging of aerosol particles has been coupled with the two-dimensional form of the convective cloud model of Clark and Collaborators. The combined model was then used to simulate a convective warm cloud for the meteorological situation which existed at 1100 LST 12 July 1985 over Hawaii; assuming an aerosol size distribution of maritime number concentration and of mixed composition with (NH4)2SO4 as the soluble compound. A shallow model cloud developed 26 min after the onset of convection leading to moderate rain which began after 45 min and ended after 60 min. Various parameters which characterize the dynamics and micophysics of the cloud, as well as the scaven…
Cyber-Security in Digital Metering Value Chain for Mountain Landslide Warning
2021
The Norwegian Water Resources and Energy Directorate (NVE) are initiating a digitalization process that involves the use of a digital metering value chain and cloud computing. The main objective of this study is to investigate how NVE can ensure cyber-security in digital meters and the cloubased metering value chain for mountain landslide warning. The study is based on a qualitative approach including methods like document analysis and semi structured interviews used as input to a risk analysis based on the ISO 31000 standard. The risk analysis covered three different scenarios from NVE. Those three scenarios were internal, external Norwegian, and transnational value chains for metering lan…
NFVMon: Enabling Multioperator Flow Monitoring in 5G Mobile Edge Computing
2018
With the advances of new-generation wireless and mobile communication systems such as the fifth-generation (5G) mobile networks and Internet of Things (IoT) networks, demanding applications such as Ultra-High-Definition video applications is becoming ever popular. These applications require real-time monitoring and processing to meet the mission-critical quality of service requirements and are expected to be supported by the emerging fog or edge computing paradigms. This paper presents NFVMon, a novel monitoring architecture to enable flow monitoring capabilities of network traffic in a 5G multioperator mobile edge computing environment. The proposed NFVMon is integrated with the management…

Software-as-a-Service Revenue Models
2013
When should software providers maintain their traditional licensing model versus offering software as a service, and which SaaS model is more profitable: rental or pay per use? For customers, what are the trade-offs between traditional licensing, renting, and paying per use? peerReviewed
