Design of an Air Management System for a Dry Room and Utilization of Waste Heat
2021
Master's thesis in Renewable energy (ENE500) This thesis presents the design of an air management system used in a dry room fora lithium-ion battery factory using a Matlab/Simulink environment. The sizing of the system is based on the 32 GWh battery factory, currently under construction by Morrow Batteries in Arendal, Norway. The generic air management system from the literature review was used as a base for the general layout and initial values. Combining coolers and a desiccant dehumidification wheel was the optimal solution for the dehumidification system. The molecular sieve was the selected desiccant due to its high performance at low relative humidity. The outlet air quality from the …

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 …
Modellering og simulering av ResQcom
2001
Masteroppgave i informasjons- og kommunikasjonsteknologi 2001 - Høgskolen i Agder, Grimstad De tre nødetatene brann, helse og politi har i dag gamle analoge kommunikasjonsnett som ønskes erstattet av et moderne digitalt nett kalt Tetra. Resqcom er et er et samlebegrep på produkter, tjenester og løsninger for nødetatene og redningstjenesten som benytter dette nettet. I denne rapporten er det gjort et forsøk på å finne ut av hvordan Resqcom kan bidra til å bedre koordinering, kvalitetsheving og effektivisering av nødetatenes koordineringintensive arbeid, gjennom bedre tilrettelegging for kommunikasjon og applikasjoner for informasjonsbehandling på Tetra-nettet. Dette er gjort ved å se nærmere…
Modelling, analysis, and simulation of mobile-to-mobile MIMO channels
2006
Masteroppgave i informasjons- og kommunikasjonsteknologi 2006 - Høgskolen i Agder, Grimstad The development of mobile communication has been dramatically increasing in recent years. New concepts and methods are necessary for the improvement of existing mobile communication techniques due to the fact of the demand for these systems with higher data rates and a better quality of service. As the number of subscribers is growing rapidly, the development of mobile radio channel models has become one of the most important research topics within mobile communication systems. This thesis deals with a multiple-input multiple-output (MIMO) channel model for mobile- to-mobile communications. It starts…
Expanding Convolutional Tsetlin Machine for Images with Lossless Binarization
2020
Master's thesis in Information- and communication technology (IKT590) Deep convolutional neural networks (CNN) is known to be efficient in image classification but non-interpretable. To overcome the black box nature of CNN a derivative of the Tsetlin automata, the convolutional Tsetlin machine (CTM) which is transparent and interpretable, was developed. As CTM handles binary inputs, it is important to transform the input images into binary form with minimum information loss so that the CTM can classify them correctly and efficiently. Currently, a relatively lossy mechanism, called adaptive Gaussian thresholding, was employed for binarization. To retain as much information as possible, in th…
Simulated testing in mobile datacom systems (GPRS/UMTS) : postgraduate thesis information and communication technology
2000
Masteroppgave i informasjons- og kommunikasjonsteknologi 2000 - Høgskolen i Agder, Grimstad The assignment described in this thesis is given by Ericsson AS and gives an evaluation of simulation and testing tools used in their development projects. Since Ericsson wants to change their testing process the task was to evaluate and suggest a solution to how this could be done. In order to make testing available for all developers it was required to run tests independent of hardware. Thus they wanted to simulate the hardware resources. Originally, the intention was to use the test environment used otherwise in Ericsson. This proved to cause many problems because the project became dependent of o…
Tapping beam recognition and measurement with infrared camera : Optimisation of an industrial process using an thermal imaging camera and computer vi…
2021
Master's thesis in Mechatronics (MAS500) This thesis presents the research and development of an application for recognition and measuring of a ferrosilicon tapping beam using an Infrared (IR) camera. Ferrosilicon production is a highly endothermic process, requiring large amounts of energy to operate; thus, the need for increased efficiency is constant. Using an IR camera for non-intrusive measurements of the tapping beam and developing computer vision algorithms that can identify distinctive process parameters are investigated in this project. Today a videostream from an IR camera overlooking the tapping area at Elkem Thamshavn is directly displayed in the tapping control room with no for…
Wavelet-based video compression: A glimpse of the future?
2004
Masteroppgave i informasjons- og kommunikasjonsteknologi 2004 - Høgskolen i Agder, Grimstad Even though wavelet-based video compression has been an area of research for more than a decade, motion estimation and compensation has been considered complex and inefficient until recently. We have carried out a thorough investigation of existing research work in this field, and found that fundamental problem with wavelet-based temporal removal while obtaining highly scalability (the wavelet-properties of multiresolution structure in combination with embedded coding), has been solved by performing motion compensated temporal filtering within the wavelet domain of a overcomplete three-dimensional li…
Incremental web crawling as a competitive game of learning automata
2005
Masteroppgave i informasjons- og kommunikasjonsteknologi 2005 - Høgskolen i Agder, Grimstad There is no doubt that the World Wide Web has lived up to it’s hype of being the world’s central information highway through the past years. An increasing amount of versatile services keeps finding their way onto the Web as information providers continue to embrace the possibilities that the Web can offer. Especially the possibility of producing dynamic content has been an accelerant factor and is the reason why we now conveniently can participate in online auctions or see the latest development of our favorite stocks in near real-time from our own living rooms. However, for automated data mining app…
