Segal Spaces in Homotopy Type Theory
(Master thesis, 2022)Homotopi type teori er et grunnleggende språk for å gjøre homotopi invariant matematikk, og dermed ville en forventet at det var et naturlig rammeverk å studere (∞,1)-kategorier i. Desverre er det for øyeblikket et åpent ... -
Topological Data Analysis and the Activations in a Convolutional Neural Network
(Master thesis, 2021)Topologisk dataanalyse (TDA) omhandler studiet av datas form. TDA kan finne verdifull kvalitativ og kvantitativ informasjon fra kompliserte dataset. Convolutional Neural Networks (CNNs) løser et mangfold av oppgaver bedre ... -
Analytical Iron Loss Evaluation in the Stator Yoke of Slotless Surface-Mounted PM Machines
(Peer reviewed; Journal article, 2022)One of the attractive benefits of slotless machines is low losses at high speeds, which could be emphasized by a careful stator core loss assessment, potentially available already at the pre-design stage. Unfortunately, ... -
Using Data Augmentation on Small Datasets to Improve Object Detection Accuracy
(Master thesis, 2021)Denne oppgaven bruker tre små datasett og augmenterer dem til flere datasett ved bruk av rotasjon, utydeliggjøring, lys og farge, mosaikk og cutout. Disse augmenterte datasettene blir deretter testet om de er bedre for ... -
Dual Use of Liquid Hydrogen in a Next-Generation PEMFC-Powered Regional Aircraft with Superconducting Propulsion
(Peer reviewed; Journal article, 2022)In this paper, we present a comprehensive model framework for a disruptive cryo-electric propulsion system intended for a hydrogen-powered regional aircraft. The main innovation lies in the systematic treatment of all the ... -
Sparse factorization of square matrices with application to neural attention modeling
(Peer reviewed; Journal article, 2022)Square matrices appear in many machine learning problems and models. Optimization over a large square matrix is expensive in memory and in time. Therefore an economic approximation is needed. Conventional approximation ... -
Multiplexed Mach-Zehnder interferometer assisted ring resonator sensor
(Peer reviewed; Journal article, 2022)A Mach-Zehnder interferometer assisted ring resonator configuration (MARC)-based multiplexed photonic sensor with a large measurement range is experimentally demonstrated. The presented MARC sensor consists of a balanced ... -
Spot, a mobile four-legged visual asset tracking robot
(Master thesis, 2022)Motivasjonen bak dette arbeidet er å foreslå et nytt visuelt sporingssystem av ressurser med målet om å lokalisere, identifisere og telle antallet konteinere i et utendørs industrielt miljø. Dette oppnås ved å bruke den ... -
A small-signal multi-frequency model for a grid-connected inverter with a more accurate PWM gain
(Peer reviewed; Journal article, 2020)It is a well known fact that pulse width modulation (PWM) produces sideband effects. Taking this point into account, the accuracy of the grid-connected inverter model can be improved. In this paper, considering the aliasing ... -
Compact and Mobile Full-Field Optical Coherence Tomography Sensor for Subsurface Fingerprint Imaging
(Peer reviewed; Journal article, 2020)Conventional fingerprint sensors that are deployed in real-life applications lack the ability to peer inside a finger beyond the external surface. Subsurface information can provide complimentary biometric characteristics ... -
