Master's thesis Renewable Energy ENE500 - University of Agder 2019 This thesis consider a case study of a PV/wind/battery hybrid energy system installed at Scanmatic ASheadquarters in Arendal, Norway. The energy system is a stand-alone and off-grid hybrid system. It consistof four PV panels of 20 W with different tilt and orientation, a wind turbine of 300 W and a battery of1.4 kWh. This work consider machine learning and artificial intelligence in Python 3 for prediction andoptimization. Machine learning is used to predict the power production from the system components basedon the weather data at site. Artificial intelligence is used to optimize the system size based on cost and theabilit…
Characterization of coating on graphite anode material for lithium-ion batteries
2021
Master's thesis in Renewable energy (ENE500) To improve the performance of lithium-ion batteries, the graphite anode can be treated with special coating. Thus the charge transfer resistance through the material can be lowered and thereby enable e.g. faster charging. The amount of coating is essential the improve the performance. The thesis is investigating thermogravimetric and electrochemical impedance spectroscopy as a method to identify an optimal relation between the amount of coating and the charge transfer resistance. There is found that lower material resistivity gives a higher weight loss where it is assumed that the coating is oxidising, methods for both a relative difference in th…
Ammonia Fuelled Solid Oxide Fuel Cell to Power Maritime Applications
2021
Master's thesis in Renewable energy (ENE500) Ammonia fuelled solid oxide fuel cell (SOFC) systems are regarded as a promising alternative for energy production due to high efficiency and low environmental impact. Ammonia is a carbon free compound with high energy density, low production cost and much simpler transport-and storage properties than hydrogen. The state-of-the-art SOFC contains a Ni/YSZ anode which has proven to be an effective catalyst to crack ammonia at intermediate temperatures (∼700°C). In this study an experimental work was conducted using an Open Flange SOFC test set-up with a planar anode-supported single cell consisting of a Ni/YSZ anode, YSZ electrolyte, and LSM cathod…

A novel learning automata game with local feedback for parallel optimization of hydropower production
2017
Master's thesis Information- and communication technology IKT590 - University of Agder 2017 Hydropower optimization for multi-reservoir systems is classi ed as a combinatorial optimization problem with large state-space that is particularly di cult to solve. There exist no golden standard when solving such problems, and many proposed algorithms are domain speci c. The literature describes several di erent techniques where linear programming approaches are extensively discussed, but tends to succumb to the curse of dimensionality problem when the state vector dimensions increase. This thesis introduces LA LCS, a novel learning automata algorithm that utilizes a parallel form of local feedbac…
Transition to a fossil- and emission-free construction industry
2018
Master's thesis Industrial Economics and Technology Management IND590 - University of Agder 2018 The object for this thesis is to see how Nettpartner, which is Norway’s largest electrical infrastructure contractor, can contribute to the green change in the construction industry. To go green has become a big topic in the Norwegian construction industry during the last few years, and in 2017 a report concluded that the Norwegian construction industry could reduce their emissions of greenhouse gases with close to 99 % if the industry planned better before they started building. The method used in this research is the constructive research. The aim of constructive research is to solve practical…

Project report : Evaluering av INSITU skogbrannøvelse
2021
Rapporten presenterer resultater fra evaluering av en digital tabletop-øvelse arrangert av INSITU-prosjektet i april 2021, der scenarioet omfattet 3 samtidige skogbranner i Agder. Hensikt med øvelsen var å gi erfaring med hvordan situasjonsbilde kan deles fra innsatsleder til sentrale myndigheter med bruk av felles digital kartstøtte. Øvelsen involverte ca. 70 deltagere fra 20 etater og organisasjoner, i tillegg til prosjektgruppen fra INSITU.
RPA og prosessledelse : En eksplorativ studie av RPA-implementering i norske bedrifter
2020
Master's thesis in Information systems (IS501) Bakgrunnen for denne utredningen har vært å undersøke om det er en sammenheng mellom Robotic Process Automation (RPA) og Business Process Management (BPM), samt hvordan norske virksomheter nyttiggjør seg av dem. I de siste årene har det i økende grad blitt populært å ta i bruk RPA for å automatiseredeler av bedrifters prosesser. Utover dette vet vi veldig lite om hvilke erfaringer virksomheter har med denne teknologien. På den annen side har vi BPM, et konsept som har blitt forsket på i flere år.Samtidig finnes det lite forskning som tar for seg både RPA og BPM. På bakgrunn av dette gjennomførte vi en forstudie høsten 2019. Her gjorde vi flere …
Development of System for Deterrence of Animals using Artificial Intelligence
2021
Master's thesis in Mechatronics (MAS500) This thesis is part of the Mechatronics masters program at the University of Agder (UiA). It describes the development of an animal deterrence system, using computer vision with embedded systems for edge computing. Household cats can run freely around in neighborhoods, but all neighbors may not appreciate it. This project seeks to develop a harmless and accurate system for keeping cats away. The solution is to use a state-of-the-art object detector to look for cats in an area. Using an embedded system to run the object detector and tracking method. Design a two-axis turret with servo motors and a camera. The object detector used for this project was …
