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 ... -
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 ... -
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 ... -
Linearization and Efficiency Enhancement of Power Amplifiers Using Digital Predistortion
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:177, Doctoral thesis, 2008) -
Linearization and Efficiency Enhancement of RF Power Amplifiers based on Advanced Measurements and Transistor Modeling
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:253, Doctoral thesis, 2010)In recent years, the development of more spectrally efficient modulation schemes, has challenged the power amplifier (PA) designers to develop more complex designs. The class AB amplifier has been the "working horse" ... -
Linearizing a Power Amplifier Using Predistortion
(Master thesis, 2009)Linear power amplication is important in radio communications to achieve high bitrates. Strong regulations of the frequency spectrum force manufacturers to use complex modulation schemes to increase the capacity. More ... -
Linelet, an Ultra-Low Complexity, Ultra-Low Latency Video Codec for Adaptation of HD-SDI to Ethernet
(Master thesis, 2014)In this project we have designed, specified, implemented, optimized and evaluated a new ultra-low latency (< 1 ms) and ultra-low complexity intra-only video compression codec, Linelet, which is able to compress 1080p50 and ... -
Link Budget for NTNU Test Satellite
(Master thesis, 2013)The NTNU Test Satellite, NUTS, is the project of Norwegian University of Science and Technology developed in the academic ambience of CubeSat scheme. Outset had placed three years ago and the plan is to be launched by 2014. ... -
