Distributed Topology for Improved Thermal Performance in RFPA Design
(Master thesis, 2022)Denne oppgaven tar for seg hvordan en distribuert topologi kan benyttes for å redusere den termiske belastningen i effektforsterkere. Dette er en høyaktuell problemstilling i moderne radiosystem med redusert effektivitet ... -
Distribution Based Spectrum Sensing in Cognitive Radio
(Master thesis, 2010)Blind spectrum sensing in cognitive radio is being addressed in this thesis. Particular emphasis is put on performance in the low signal to noise range. It is shown how methods relying on traditional sample based estimation ... -
Diving-wave time-lapse delay for CO2 thin layer detection
(Peer reviewed; Journal article, 2024)We have derived an analytical approximate expression to estimate the delay in diving seismic waves due to thin layers of CO2. The expression is valid for high frequencies and can be used to estimate the delay in diving ... -
DML in VIDEO-CONFERENCING APPLICATIONS
(Master thesis, 2012)Today's audio in video-conference rooms do not in general have high quality audio standards.Most of the set-ups are PC-Speakers mounted on the wall, with a microphone on the table. With this, strong room modes are often ... -
DNA walks in virus genomics
(Journal article; Peer reviewed, 2024)This paper studies published results in imaging and digital processing of virus RNAs (ribonucleic acid) using DNA (deoxyribonucleic acid) walks. The complicated nature and physicochemical properties of these nucleotide ... -
A DNN Based Speech Enhancement Approach to Noise Robust Acoustic-to-Articulatory Inversion
(Chapter, 2021)In this work, we investigate the problem of speaker independent acoustic-to-articulatory inversion (AAI) in noisy condition within the deep neural network (DNN) framework. We claim that DNN vector-to-vector regression for ... -
Do Students Reflect on Sustainability? Student Development of Competencies for Sustainability in Project-Based Learning
(Peer reviewed; Journal article, 2023)Higher education plays a crucial role in supporting a society based on sustainable development through the facilitation of students’ acquisition of competencies for sustainable development. A suitable arena in which to ... -
Documenting skin bruises with smartphone imaging
(Master thesis, 2021)Målet med denne oppgaven er å utvikle og teste en standardisert metode for dokumentasjon av blåmerker. En slik metode kan bidra til å forbedre rettsmedisinsk bevis i rettsaker som omhandler vold og kan bistå helsepersonell ... -
Doherty effektforsterker for 1,8 GHz
(Master thesis, 2007)Formålet med denne oppgaven er å designe en Dohertyforsterker. En klasse AB og en klasse C effektforsterker til bruk i denne konfigurasjonen skal designes, simuleres og gjøres målinger på hver for seg. Disse skal så å bli ... -
Dopant incorporation in Al0.9Ga0.1As0.06Sb0.94 grown by molecular beam epitaxy
(Journal article, 2017)Incorporation of beryllium (Be) and tellurium (Te) dopants in epitaxially grown Al0.9Ga0.1As0.06Sb0.94 layers was investigated. Carrier concentrations and mobilities of the doped layers were obtained from room temperature ... -
Doppler Radar Speed Measurement Based On A 24 GHz Radar Sensor
(Master thesis, 2013)This thesis will present the implementation of an on-board speed measurement system using a single 24.1 GHz Doppler radar sensor and specialized algorithms to measure the true speed of a vehicle. Two different algorithms ... -
Doppler radar speed measurement on board - digital signal processing
(Master thesis, 2013)Abstract Doppler radars have been widely used in many different fields, such as traffic control, weather prediction, navigation, satellite tracking, Airborne Early Warning systems and missile guidance. The technology ... -
DPA-Resistant ASIC implementation of AES
(Master thesis, 2015)With the increased proliferation of small embedded systems connected to the internet and the internet-of-things, the security concerns becomes increasingly important. Encryption, and the protection of encrypted circuits ... -

(Bachelor thesis, 2021)I denne oppgaven har målet vært å finne svakheter i sikkerheten hos to droner, og med den informasjonen få en oversikt over hvilken grad sikkerheten til kommersielle droner ligger på. Dronene som har blitt undersøkt er ... -
DSP Extension for AVR10 CPU
(Master thesis, 2007)When Digital Signal Processors were first introduced in the early 80 s they were significantly faster than general microprocessors at performing digital signal processing (DSP) algorithms. The advantages of having specialised ... -
DSP for Lågeffekt Programvaredefinert Radio
(Master thesis, 2011)Programvaredefinert radio (SDR) er ein ny måte å implementere radiosystem på. Hovudtanken er at delar av radioen som tidlegare har vore implementert med låste analoge og digitale løysingar skal erstattast med programvare ... -
Dual parameter fiber optic sensor combining a Fabry-Perot and a Mach-Zehnder interferometer
(Journal article, 2017)A new concept for dual parameter fiber optic sensor has been developed and characterized, both in a two-fiber and single-fiber configuration. The liquid sensor measures ethanol concentration with a stimuli responsive ... -
