A method for remote sensing of acoustic ship noise
(Master thesis, 2013)Ship noise in the ocean due to commercial shipping has gained increased interest in recent years because of its potential impact on marine life and the ocean environment. Hence, rapid methods to estimate the source level ... -
A Method of Designing Wide Dispersion Waveguides Using Finite Element Analysis
(Master thesis, 2011)High frequency dispersion has a great influence on the perceived performance of a loudspeaker. The directivity of a single transducer primarily depends on driver size, however directivity can be modified using an acoustical ... -
A miniaturized ball-lensed fiber optic NIR transmission spectroscopy-based glucose sensor
(Chapter, 2018)A novel ball-lensed fiber transmission sensor is presented aimed at in vivo continuous glucose monitoring of diabetics. Preliminary results yield 20 mM RMSE, limited by mechanical instability. The design enables flexibility ... -
A Narrowband SDR Transceiver for Amateur Radio Applications: Hardware Design and Construction
(Master thesis, 2013)A VHF radio transceiver targeted for maximum efficiency and flexibility in CubeSat- and UAV applications has been designed, constructed and tested subsystem by subsystem, and ultimately as a complete system. The best case ... -
A Novel Analog Front-End For ECG Acquisition
(Master thesis, 2012)A complete analog front-end for portable ECG systems in 65nm technology was modeled and simulated using Cadence Virtuoso. All the required components for the AFE was incorporated into the continuous-time loop filter of a ... -
A numerical method for junctions in networks of shallow-water channels
(Journal article, 2018)There is growing interest in developing mathematical models and appropriate numerical methods for problems involving networks formed by, essentially, one-dimensional (1D) domains joined by junctions. Examples include ... -
A One-Sensor System for Home Diagnosis and Therapy of Snoring and Sleep Apnea
(Master thesis, 2007)The average sleeping time suffers from a more and more stressful life, and is now close to the limit of what the human being can bear. Therefore, a good quality sleep is more important than ever. At the same time, the ... -
A Parallel FPGA Implementation of the CCSDS-123 Compression Algorithm
(Journal article; Peer reviewed, 2019)Satellite onboard processing for hyperspectral imaging applications is characterized by large data sets, limited processing resources and limited bandwidth of communication links. The CCSDS-123 algorithm is a specialized ... -
A Pragmatic Approach to Modulation Scaling Based Power Saving for Maximum Communication Path Lifetime in Wireless Sensor Networks
(Master thesis, 2008)The interest in Wireless Sensor Networks is rapidly increasing due to their interesting advantages related to cost, coverage and network deployment. They are present in civil applications and in most scenarios depend upon ... -
A Priori Spectroscopy of Coffee Roasts
(Master thesis, 2021)Før brygging må kaffe brennes. Kaffebrennere ønsker så mye kontroll over brenneprosessen som mulig. I dag er kaffebrenning for det meste manuelt arbeid med lite eller ingen instrumentering. Kjemisk sammensetning er viktig ... -
A programmable DSP for low-power, low-complexity baseband processing
(Master thesis, 2006)Software defined radio (SDR) is an emerging trend of radio technology. The idea is basically to move software as close to the antenna of a radio system as possible, to improve flexibility, adaptability and time-to-market. ... -
A radar simulator for generating micro-Doppler datasets to be used for Automatic Target Recognition
(Master thesis, 2018)To train a classifier used for automatic target recognition, a large dataset of annotated target signatures is needed. Obtaining such datasets from real recordings can be very time-consuming. Therefore a system for generating ... -
A random forest-based method for selection of regions of interest in hyperspectral images of ex vivo human skin
(Journal article; Peer reviewed, 2019)Hyperspectral imaging is a useful tool for characterization of human tissue. However, the vast amount of data created makes it challenging and tedious to manually select spatial regions of interest for further processing. ... -
