Source level and vocalizing depth estimation of two blue whale subspecies in the western Indian Ocean from single sensor observations
(Peer reviewed; Journal article, 2021) -
Source localization in the ocean via machine learning
(Master thesis, 2018)This study investigated source localization in the ocean using machine learning meth-ods. By interpreting the sound waves emitted by the source, localization can be acquired.In order to interpret the pressure, the machine ... -
Source Range Estimation in the Ocean using Time Difference of Multipath Arrivals
(Master thesis, 2016)Passive acoustic ranging in the underwater channel is a challenging task. It has been studied and used in military applications such as passive sonar, but also by marine biologists for mammal detection and ranging. Effective ... -
Spatial Bias in Vision-Based Voice Activity Detection
(Peer reviewed; Journal article, 2021)We develop and evaluate models for automatic vision-based voice activity detection (VAD) in multiparty human-human interactions that are aimed at complementing acoustic VAD methods. We provide evidence that this type of ... -
Spatial Storytelling: Finding Interdisciplinary Immersion
(Chapter, 2018)This paper is part of an ongoing transdisciplinary research into immersion. In specific, it focuses on Spatial Storytelling to examine the narrative technique in conjunction with Spatial Presence, a commonly accepted subtype ... -
Spatially Confined Spin Polarization and magnetic sublattice control in (La,Sr)MnO3−δ Thin Films by Oxygen Vacancy Ordering
(Journal article; Peer reviewed, 2017)Perovskite oxides are known for their strong structure property coupling and functional properties such as ferromagntism, ferroelectricity and high temperature superconductivity. While the effect of ordered cation vacancies ... -
Spatio-Temporal Decision Fusion for Quickest Fault Detection Within Industrial Plants: The Oil and Gas Scenario
(Chapter, 2021)In this work, we present a spatio-temporal decision fusion approach aimed at performing quickest detection of faults within an Oil and Gas subsea production system. Specifically, a sensor network collectively monitors the ... -
Speckletracking i ultralyd IQ-data
(Master thesis, 2008)Målet med denne oppgaven er å forbedre speckletracking i ultralyd hjerteavbildning. Dette gjør jeg ved å bruke hastighetsinformasjon, utregnet fra fasevinkelen fra to etterfølgende pulser. Det gir oss mer nøyaktig ... -
Spectral diagnostics and characterization of atopic dermatitis in children's health - A Hyperspectral Imaging System using an Acousto-Optic Tunable Filter
(Master thesis, 2017)Hyperspectral imaging with high spectral and spatial resolution can be used to analyse material using spectroscopic methods. This technique can be applied to human tissue as a general purpose diagnostics tool and as an aid ... -
Spectral impairment in HRTF based binaural reproduction systems
(Master thesis, 2017)Higher Order Ambisonics is a method for capturing and reproducing sound fields. With Ambisonics` advantageous features and possibilities for binaural reproduction, the method has been established as one of the best ways ... -
Spectral shaping of ring resonator transmission response
(Peer reviewed; Journal article, 2021)We present a Mach-Zehnder interferometer assisted ring resonator configuration (MARC) to realize resonator transmission spectra with unique spectral signatures and significantly large effective free spectral ranges. ... -
Speech adaptation of special voice classes
(Master thesis, 2011)Most automatic speech recognition systems are based on statistical models thatrequire training. While these types of systems have reached recognition ratesthat are sufficient for many purposes, they perform poorly for ... -
Speech Analysis for Automatic Speech Recognition
(Master thesis, 2009)The classical front end analysis in speech recognition is a spectral analysis which parametrizes the speech signal into feature vectors; the most popular set of them is the Mel Frequency Cepstral Coefficients (MFCC). They ... -
Speech Enhancement with Deep Neural Networks
(Master thesis, 2016)This master thesis describes the implementation and evaluation of a promising approach to speech enhancement based on deep neural networks. A baseline system was imple- mented and trained using noisy data synthesized by ... -
Speech Generation and Modification in Concatenative Speech Synthesis
(Doctoral Theses at NTNU, 1503-8181; 2010:68, Doctoral thesis, 2010) -
Speeding up SURF Imaging: New Methods to Increase Frame Rate in Multi-Pulse Ultrasound Imaging Modalities
(Master thesis, 2013)Any good medical ultrasound imaging system must be able to resolve anatomical structures properly, and simultaneously provide adequate frame rate so that moving structures can be studied with ease. In a conventional imaging ... -
Spherical Microphone Array Signal Processing on FPGA
(Master thesis, 2010)Spherical microphone arrays are finding an increasing number of applications, mainly because of their ability to describe the directionality of sound captured, and the ease with which this information can be used, e.g., ... -
Spoken Document Classification of Broadcast News
