Konstruksjon av klasse F effektforsterker
(Master thesis, 2006)Effektforsterkere er viktige komponenter i dagens telekommunikasjonsutstyr. I de fleste trådløse kommunikasjonssystemer står effektforsterkeren for en stor andel av det totale effektforbruket. Derfor er virkningsgraden, ... -
Konstruksjon av ultralydbad: med tanke på akustisk kavitasjon
(Master thesis, 2010)I dag er biofilm på proteser operert inn i kroppen årsak til infeksjonar og pasientsmerter. Ein ynskjer å vite om kavitasjon kan nyttast til å fjerne denne biofilmen. Tidlegare medisinske studiar med kommersielt tilgjengelege ... -
Laboratory experiments on ultrasonic logging through casing for barrier integrity validation
(Chapter, 2017)Verification of annular barriers is essential for well integrity, with ultrasonic methods being central in well integrity testing for many decades. By doing ultrasonic pitch-catch measurements on a bench top laboratory ... -
Language Identification Based on Detection of Phonetic Characteristics
(Master thesis, 2012)This thesis has taken a closer look at the implementation of the back-end of a language recognition system. The front-end of the system is a Universal Attribute Recognizer (UAR), which is used to detect phonetic characteristics ... -
Large Area Patterning of Embedded Magnetic Nanostructures in Complex Oxide Thin Films
(Master thesis, 2015)Complex oxide materials exhibit a wide range of functional properties, making them interesting for future use in electronic and spintronic devices. Through nanopatterning of thin film structures, magnetic shape effects can ... -
Large-scale Offshore Wind Development and Decarbonization Pathways of the Norwegian Energy System
(Chapter, 2023)Modelling of the energy system in the countries surrounding the North Sea is performed with a focus on Norway and offshore wind farms situated in the North Sea. The geographically heterogeneous consumption and production ... -
Lattice Boltzmann Simulation of Acoustic Fields, with Special Attention to Non-reflecting Boundary Conditions
(Master thesis, 2014)Non-reflecting boundary conditions (NRBCs) are of great importance in computational fluid dynamics. Ideal NRBCs will fully absorb every incoming wave, thereby eliminating reflections from the boundaries which would otherwise ... -
Lav effekt sensornettverk, for registrering av kjøretøy
(Master thesis, 2015)Denne prosjektoppgaven omhandler design og implementasjon av et lavenerginettverk bestående av parkeringssensorer. Dataen som skal sendes vil være om det er en bil parkert på parkeringsplassen, eller ikke. Systemet vil ha ... -
Laveffekts sensorkommunikasjon ved hjelp av multiple transmisjoner og tilbakekopling for bekjempelse av gausse- og impulsstøy
(Master thesis, 2008)I denne oppgaven skal en studere hvordan et inkremental transmission system kan bekjempe impulsstøy i tillegg til gausstøy. En strategi kan være at når mottakeren detekterer unormalt store vedier, forsøker den å gi beskjed ... -
Lavfrekvent ventilasjonsdemper
(Master thesis, 2011)Støy fra ventilasjonsanlegg inneholder ofte en stor del lave frekvenskomponenter, som er vanskelig å dempe med konvensjonelle lyddempere. Dempere som tar slike lave frekvenser er normalt veldig store og plasskrevende, eller ... -
Lavkost diskret ordgjenkjenner på enkel mikrokontroller
(Master thesis, 2006)Diskrete ordgjenkjenner på en Atmel Mega32. Benytter Dynamic Time Warping og Mel-Frequency Cepstral Coeffisients. -
LED light source for hyperspectral fluorescence imaging
(Master thesis, 2012)This report deals with the possibility of creating a LED light source, to be used withhyperspectral fluorescence imaging. There are commercially available light sources thatcould be used, but they are expensive, they do ... -
Lens Flare Attenuation Accelerator Design with Deep Learning and High-Level Synthesis
(Chapter, 2023)Lens flare artifacts are undesired visual distortions caused by stray light, which can negatively impact the integrity and quality of an image. These artifacts pose a significant challenge in industrial applications like ... -
Leveraging a Convolutional Neural Network for Real-Time Classification of Distributed Acoustic Sensing Data alongside a Railway
(Master thesis, 2024)Formålet med dette forskningsprosjektet var å utvikle et rammeverk for et sanntidsovervåkningssystem for jernbaner, ved bruk av "distributed acoustic sensing" data og et konvolusjonelt nevralt nettverk. For å nå dette ... -
Lexical Robustness for Automatic Speech Recognition
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:214, Doctoral thesis, 2012)The lexicon plays a crucial role in a speech recognition system. It defines the mapping between the words that the system can recognize and the different ways these words can be pronounced. In this thesis we address various ... -
Linear MMSE Precoder Combiner Designs for Decentralized Estimation in Wireless Sensor Networks
(Chapter, 2020)This work considers the design of linear minimum mean square error (MMSE) precoders and combiners for the estimation of an unknown vector parameter in a coherent multiple access channel (MAC)-based multiple-input multiple-output ... -
Linear sweeps and the characterisation of linearly time-varying acoustical systems
(Journal article, 2024)Sine sweeps are widely used as test signals in the experimental characterisation of linear and non-linear acoustical systems' responses. One of the reasons for their popularity is that their immunity against time variance ... -
