The on-line coupled atmospheric chemistry model system MECO(n) – Part 5: Expanding the Multi-Model-Driver (MMD v2.0) for 2-way data exchange includin…
2018
Abstract. As part of the Modular Earth Submodel System (MESSy), the Multi-Model-Driver (MMD v1.0) was developed to couple online the regional Consortium for Small-scale Modeling (COSMO) model into a driving model, which can be either the regional COSMO model or the global European Centre Hamburg general circulation model (ECHAM) (see Part 2 of the model documentation). The coupled system is called MECO(n), i.e., MESSy-fied ECHAM and COSMO models nested n times. In this article, which is part of the model documentation of the MECO(n) system, the second generation of MMD is introduced. MMD comprises the message-passing infrastructure required for the parallel execution (multiple programme mul…
Hvordan påvirkes arbeidsprosesser ved innføring av EPJ og velferdsteknologi på sykehjem
2018
Masteroppgave i helse- og sosialinformatikk HSI500 - Universitetet i Agder 2018 In order to be better equipped in the challenges of the future, with an increasing number of elderly and fewer professionals to care for them, the government emphasizes the importance of service innovation in the healthcare sector. Change is required to gain socioeconomic benefits, particularly in work processes. More frequent and better use of electronic medical record (EMR) and welfare technology is necessary. The purpose of this study was to bring information and knowledge about how using technology in the nursing homes has transformed the work processes. Qualitative, exploratory method with semi-structured i…

PSIM-Based Hardware and Software Design of an Inverter-Fed Permanent Magnet Synchronous Motor
2018
Master's thesis Renewable Energy ENE500 - University of Agder 2018 The purpose of this research is to design a PSIM based controller for an inverter-fed Permanent Magnet Synchronous Motor (PMSM). The dimensioning and assembly of the controller are presented. The control algorithm used for the PMSM is Field Oriented Control (FOC). The report includes the theory of the control algorithm and its design. A PSIM based model is designed with the dimensioned components to analyse the behaviour of the controller. The model gives the opportunity of tuning the controller and verifying it with simulations. The model is then converted to be SimCoder compatible, enabling the simulation to be generated i…
Power Prediction of Photovoltaic System using Neural Network Models
2019
Master's thesis Renewable Energy ENE500 - University of Agder 2019 This workconsidersa photovoltaic (PV)system installed on the rooftop of Agder Energi’s headquarters located at Kjøita, Kristiansand. The system includes three different types of solar PV modules; Suntech (multi-Si), Sharp (a-Si/μ-Si) and REC (multi-Si), that have a total installed DC capacity of 45 kWp. The system is grid-connected and instrumented for research and monitoring purposes.Artificial Neural Network(ANN)models were trained to obtain the lowest mean square error(MSE), by testing different configurations using a model-based trial and error approach. The modelconfigurations that gavethe lowest(MSE) wereused to predic…
South Pole glacial climate reconstruction from multi-borehole laser particulate stratigraphy
2013
AbstractThe IceCube Neutrino Observatory and its prototype, AMANDA, were built in South Pole ice, using powerful hot-water drills to cleanly bore>100 holes to depths up to 2500 m. The construction of these particle physics detectors provided a unique opportunity to examine the deep ice sheet using a variety of novel techniques. We made high-resolution particulate profiles with a laser dust logger in eight of the boreholes during detector commissioning between 2004 and 2010. The South Pole laser logs are among the most clearly resolved measurements of Antarctic dust strata during the last glacial period and can be used to reconstruct paleoclimate records in exceptional detail. Here we use…
Fornøyd med litt men ønsker seg likevel mer : gir nye versjoner av EPJ-system i helse- og omsorgssektoren i kommunene kontinuerlig forbedring?
2016
Masteroppgave i helse- og sosialinformatikk- Universitetet i Agder, 2016 Continuous development in health- and care services leads to the electronic patient record (EPR) systems to become more complex. It is important for municipalities to have systems that work, and acts as a support for workflows of everyday life, so that information regarding the patients are easily accessible and accurate. It is therefore important that new versions of EPR systems are delivered with good quality. This study focuses on municipalities' challenges with developing, testing and implementing new versions of old EPR system in health- and caregiving services. A qualitative study is conductet, with interviews of…
Water erosion prediction by stochastic and empirical models in the Mediterranean: A case study in Northern Sicily (Italy)
2012
The present thesis aimed to explore the methodological advantages as well as limitations in applying different modelling approaches to predict water soil erosion in Mediterranean environments. The research was accomplished in the central northern part of Sicily (Italy), considering this region to be representative of Mediterranean environmental conditions. In this region soil degradation problems, due to water erosion are becoming more and more serious. Consequently, defining models being able to predict erosion susceptibility and to discriminate environmental factors causing erosion is important to protect soil resources. The prediction of the spatial distribution of soil erosion processes…
Atmospheric components determination from ground-level measurements during the spectra Barax Campaigns (SPARC) field campaigns
2007
The Surface Processes and Ecosystem Changes Through Response Analysis (SPECTRA) Barrax Campaigns were validation campaigns developed in the framework of the SPECTRA mission in order to verify that the geophysical data products provided by satellite imagery are consistent with the measurements made by independent means. Two campaigns took place in Barrax, Spain, during the summers of 2003 and 2004. This paper presents the results of the characterization of the atmospheric composition from solar radiation, radiosoundings, and lidar measurements. Several potentially interesting situations involving atmospheric layers with different types of aerosols and water content are discussed. The presenc…
First results from the PROBA/CHRIS hyperspectral/multiangular satellite system over land and water targets
2005
The Project for On-Board Autonomy (PROBA) platform developed by the European Space Agency was launched on October 22, 2001. The instrument payload includes the Compact High Resolution Imaging Spectrometer (CHRIS). The coupled system provides high spatial resolution hyperspectral/multi-angular data, which represents a new-generation source of information for Earth observation purposes. The first results obtained from the preprocessing (noise removal and geometric/atmospheric correction) of two different datasets, collected over agricultural crops and inland waters, are presented in this letter. In situ measurements are used to assess the quality of the data and to validate the processing alg…
