A framework for the simulation and validation of acoustic fields from medical ultrasound transducers
Bakstad, Ole (Master thesis, 2012)The unified simulation framework for medical ultrasound, FieldSim, cur- rently supports linear and non-linear simulations by using Field II and Aber- sim, respectively. In this thesis the quasi-linear simulation tool, ... -
A High Speed Low Cost Capacitor Reset Circuit
Løvseth Finnøy, Torbjørn (Master thesis, 2011)This master thesis presents the investigation and design of a capacitor reset circuit. The circuit was implemented and simulated using a standard 0.35µm CMOS process. A capacitive load of 20pF should be reset at 0.1% ... -
A Measurement Allocation Scheme for Reliable Data Gathering in Spatially Correlated Sensor Networks
Byun, Sang-Seon; Balasingham, Ilangko (Chapter, 2010) -
A method for remote sensing of acoustic ship noise
Coward, Stian (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 Applying Single Higher Order Polynomial Basis Function over Multiple Domains
Lysko, Albert (Chapter, 2010) -
A Method of Designing Wide Dispersion Waveguides Using Finite Element Analysis
Solgård, Tom Alexander (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 Narrowband SDR Transceiver for Amateur Radio Applications: Hardware Design and Construction
Skagmo, Jon Petter (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
Theie, Øyvind Bjørkøy (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 One-Sensor System for Home Diagnosis and Therapy of Snoring and Sleep Apnea
Hofsøy, Dan Anker (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 Pragmatic Approach to Modulation Scaling Based Power Saving for Maximum Communication Path Lifetime in Wireless Sensor Networks
Malavia Marín, Raúl (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 programmable DSP for low-power, low-complexity baseband processing
Næss, Hallvard (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 satellite system for broadband communications to polar areas
Løge, Lars (Master thesis, 2008)Over the last few years the ship traffic in polar areas have been steadily increasing, especially north of Norway. This is largely due to the growing activity in that area and in northern Russia, mainly from oil and gas ... -
A Scientific Tool for Real-time Acquisition and Analysis of Cardiovascular Measurements: Including ultrasound and other physiological data sources
Wigen, Morten Smedsrud (Master thesis, 2013)En programvare for studier av karsystemet, for både eksperimentelle og kliniske forsøk, skal utvikles i denne oppgaven. Data fra både ultralyd og andre fysiologiske kilder, som trykk, blodstrøm og volum, skal kunne mottas ... -
A study of Forward Models in Seismic Inversion
Nilsen, Maria (Master thesis, 2007)Knowledge about the physcical parameters of the seafloor is often important information. This master s thesis looks at seismic inversion to find these parameters. The choice of forward model is highly emphasised. A seismic ... -
