Individual-particle analysis of airborne dust samples collected over Morocco in 2006 during SAMUM 1
2011
During the course of SAMUM 1 in May and June 2006, airborne samples were collected in southern Morocco at altitudes between 830 and 3340 m above ground. We analysed approximately 22 500 particles of 1–30 μm by automated individual-particle analysis with a scanning electron microscope (SEM) and an energy-dispersive X-ray (EDX) analyser. The major difference between samples is due to the presence and amount of chlorine- and sulphur-bearing particles, pointing to a varying maritime influence and to different degrees of aging. In contrast, the desert dust component is very homogeneous independent of altitude, activated local source area, and dust storm intensity, implying very fast mixing of th…

Comparative Ab Initio Calculations of ReO3, SrZrO3, BaZrO3, PbZrO3 and CaZrO3 (001) Surfaces
2020
We performed, for first time, ab initio calculations for the ReO2-terminated ReO3 (001) surface and analyzed systematic trends in the ReO3, SrZrO3, BaZrO3, PbZrO3 and CaZrO3 (001) surfaces using first-principles calculations. According to the ab initio calculation results, all ReO3, SrZrO3, BaZrO3, PbZrO3 and CaZrO3 (001) surface upper-layer atoms relax inwards towards the crystal bulk, all second-layer atoms relax upwards and all third-layer atoms, again, relax inwards. The ReO2-terminated ReO3 and ZrO2-terminated SrZrO3, BaZrO3, PbZrO3 and CaZrO3 (001) surface band gaps at the &Gamma
Palvelukeskeisen arkkitehtuurin suunnittelumenetelmät
2009
Alamaa, Jari Markus Palvelukeskeisen arkkitehtuurin suunnittelumenetelmät / Jari Alamaa Jyväskylä: Jyväskylän yliopisto, 2008, 42 s. Kandidaatintutkielma Nykypäivän nopeasti muuttuva liiketoiminnan tehtäväkenttä asettaa tietojärjestelmät uudenlaisien haasteiden eteen. Tietojärjestelmien vaatimustaso on noussut, ja järjestelmän joustavuudesta sekä tehokkuudesta on tullut merkittävä kilpailutekijä. Tilanteen ratkaisemiseksi on oman vastauksensa antanut palvelukeskeinen arkkitehtuuri, joka on teknologiariippumaton ajatusmalli arkkitehtuurin toteuttamiseen. Palvelukeskeinen arkkitehtuuri mahdollistaa tietojärjestelmän toimintojen ja vanhojen perinnejärjestelmien uudelleenkäytön sekä tietojärj…
Standardisering av brokonstruksjoner for nasjonale hovedveier
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Standardization is currently not being utilized much in the Norwegian road building industry compared to the rest of the construction industry and road construction abroad. To harvest the potential benefits, it is interesting to determine how to increase the use of standardization in road building. The aim of this master’s thesis is to determine how to make use of standardized concrete bridges for the construction of new national highways. To investigate this, the thesis has established knowledge on today’s situation and found dominant obstacles towards a more widespread use of standardized bridge solutions. The Norwegian Public Roads A…
Standardiserte konstruksjonselementer av fiberarmert polymer for vegbru : Design og dimensjonering av elementer for standardisering og bruk i vegbruer
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 This thesis is addressing the possibility for use of fiber reinforced polymers (FRP) in bridge constructions in Norway. The aim is to design an FRP section that can perform as both structural support and decking on the bridge, in a similar way as often is done with concrete. The advances of using FRP composites is that it is possible to make the bridge sections a lot lighter, and consequently possible to fabricate them in remote locations and transport them to the construction site. This will make the time necessary for construction on site a lot shorter in cases where old bridges need replacement. To make FRP-composite bridges economic…
Dimensjonering av slank balkong i Ultra-High Performance Fibre-Reinforced Concrete
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 As part of the fifth and final year in civil engineering at University of Agder, this master’s thesis has been composed. This report was written during the spring semester of 2017. The purpose of this thesis was to dimension a slim balcony in UHPFRC. Nor Element wanted to be able to produce slim balconies in their own production facilities. Nor Element is currently producing balconies, but these have thicker cross sections. This master’s thesis involves a literature study and a dimension process. In the literature study the relevant guidelines and Eurocodes are presented. The study contains relevant formulas and recommendations needed t…
Rehabilitering av antikvarisk betongkonstruksjon fra perioden 1926-1938 : Vurdering av rehabiliteringstiltak og restkapasitet for Ingierstrand bad, b…
2017
Masteroppgave bygg BYG500 - Universitetet i Agder 2017 Traditionally restoration of antiquarian concrete constructions has been a prominent topic in Norwegian context. This topic has been given more attention, as more concrete constructions and reinforced concrete constructions have been preserved. In this thesis a case-study were done of Ingierstrand bad. A central part of the restoration of antiquarian concrete constructions is to control the capacity of the concrete against occurring stresses. We have in this thesis theoretically controlled the capacity of the standard being used during projecting and building, and that of today’s standard. We suggested the actions of restoration we thin…
Samvirkekonstruksjoner av stål og betong i boligbygg : Dimensjonering og modellering med hensyn til preakseptering, Eurokode 4 og numerisk analyse
2021
Master's thesis in Civil and structural engineering (BYG508) Interaction between steel and concrete, and its effect on moment capacity and flexural stiffness was investigated through the subject BYG507 - Preliminary Project to the Masters Thesis. As a continuation of the preliminary project, this report aims to establish an increased understanding of composite structures, with regards to capacity, modelling and current use. Based on regulations given in Eurocode 4, both pre-accepted and non-pre-accepted composite solutions are considered. The non-pre-accepted solution is based on an actual project; Kanalen Brygge in Tønsberg. This report is based on literature study, calculations and numeri…

2018
Masteroppgave bygg BYG508 - Universitetet i Agder 2018 This master-thesis investigates the effects on multi-story buildings generated by seismic loading and the potential diversity of results based on wrong assumptions in an early stage of engineering. A point of focus has been the different capacities of the horizontal slabs in the building, and if it is possible to use results from the modal-analysis directly for further calculations. Because seismic loading often causes large horizontal forces, we have also considered different methods for improving capacities regarding in-plane shear-forces. The results indicate that some factors affect the results considerably relative to the forces th…
