Rekonstruksjon av ultralyd blodhastighetsfelter basert på Dyp Læring
(Master thesis, 2020)Ny forskning viser at avvik fra normal blodstrøm i venstre ventrikkel kan være et tidlig tegn på hjertesykdom. Nøyaktig screening av blodstrøm i venstre ventrikkel kan hjelpe leger å gi passende behandling til pasienter ... -
Investigation of High Accuracy Mixed-Signal Time-to-Digital Converter
(Master thesis, 2020)I denne masteroppgaven er hovedmålet å måle tiden mellom stigende flanker av to separate signaler. Det ble foreslått å bruke en såkalt ”Vernier Delay Line” (VDL), men problemet med dem er at nøyaktigheten er inkonsekvent ... -
Optimization and fabrication of a fiber-to-waveguide silicon-on-insulator grating coupler
(Master thesis, 2020)Utviklingen av miniatyriserte laboratoriesystemer har blitt et viktig forskningsområde innen integrert fotonikk de siste årene. Mange av disse systemene baserer seg på lysmodulerende strukturer som krever tilstrekkelig med ... -
Automatic annotation of lecture videos for multimedia driven pedagogical platforms
(Peer reviewed; Journal article, 2016)Today’s eLearning websites are heavily loaded with multimedia contents, which are often unstructured, unedited, unsynchronized, and lack inter-links among different multimedia components. Hyperlinking different media ... -
Impact of Silanization Parameters and Antibody Immobilization Strategy on Binding Capacity of Photonic Ring Resonators
(Peer reviewed; Journal article, 2020)Ring resonator-based biosensors have found widespread application as the transducing principle in “lab-on-a-chip” platforms due to their sensitivity, small size and support for multiplexed sensing. Their sensitivity is, ... -
Tunable photo-responsive elastic metamaterials
(Peer reviewed; Journal article, 2020)The metamaterial paradigm has allowed an unprecedented space-time control of various physical fields, including elastic and acoustic waves. Despite the wide variety of metamaterial configurations proposed so far, most of ... -
Cooperative communications with relay selection for wireless networks: design issues and applications
(Peer reviewed; Journal article, 2013)Relay selection schemes for cooperative communications to achieve full cooperative diversity gains while maintaining spectral and energy efficiency have been extensively studied in a recent research. These schemes select ... -
Hyperspectral imaging for detection of arthritis: Feasibility and prospects
(Peer reviewed; Journal article, 2015)Rheumatoid arthritis (RA) is a disease that frequently leads to joint destruction. It has a high incidence rate worldwide, and the disease significantly reduces patients’ quality of life. Detecting and treating inflammatory ... -
Optimal Operation Mode Selection for Energy-efficient Light-weight Multi-hop Time Synchronization in Linear Wireless Sensor Networks
(Peer reviewed; Journal article, 2020)We explored the joint effect of synchronization window and offset/drift mode selection on the time synchronization of linear wireless sensor networks (LWSNs). Recent advances in the field along with the availability of ... -
VR i Sport
(Master thesis, 2020)Repeterende utholdenhetsøvelser gjort innendørs, som å løpe på en tredemølle eller ro på et ro-ergometer pleide å være ensformig og kjedelig. Bruk av ny teknologi i idrett og andre fysiske aktiviteter er i kraftig vekst, ... -
Fractional-order correntropy filters for tracking dynamic systems in alpha-stable environments
(Peer reviewed; Journal article, 2020)In an increasing number of modern filtering applications, the encountered signals consist of frequent sharp spikes, that cannot be accurately modeled using Gaussian random processes. Modeling the behavior of such signals ... -
Narrative’s Impact on Quality of Experience in Digital Storytelling
(Chapter, 2019)Our ways of telling stories have evolved along with advances in technology. This has led to the emergence of digital storytelling. This project explores narrative influences on Quality of Experience of users in digital ... -
Objektiv og sansningsbasert vurdering av vindturbinstøy
(Master thesis, 2020)De fleste land benytter i dag regelverk for regulering av støyplage fra vindturbiner som er basert på lydtrykknivå, mens noen land bruker differensielle støygrenser som lydfremvekst. I denne sammenhengen har det blitt ... -
A high-voltage cascode-connected three-level pulse-generator for bio-medical ultrasound applications
(Peer reviewed; Journal article, 2019)This paper presents a high-voltage three-level pulse-generator circuit which reduces the driving requirement of the input signals. This is achieved by cascoding making it possible to use low-voltage input transistors. The ... -
