Challenges of the Use of Sound Emergence for Setting Legal Noise Limits
(Journal article; Peer reviewed, 2019)In the vast majority of legislation on environmental noise, the metric used for expressing limit values is based on sound pressure levels. But some countries have introduced sound emergence limit values where the compliance ... -
Channel Evaluation with Distributed Base Stations for Wireless Sensor Network Support
(Master thesis, 2020)This paper compares the quality of a channel within a rectangular space given the variables: number of base stations, number of antenna elements, base station locations, and richness of scattering in the environment. ... -
Channel Filter Cross-Layer Optimization
(Master thesis, 2015)The recent raise of Internet of Things has increased the demand of energy-efficient wireless devices. However, the design process of a low-energy, high-performance device for all operational cases is not trivial. Thus, in ... -
Channel measurements and channel modeling for the open sea
(Doktoravhandlinger ved NTNU, 1503-8181; 2013:172, Doctoral thesis, 2013)Maritime communication plays an important role in the marine activities. However, insufficient knowledge of radio channel characteristics over the sea is a limiting factor in the development of wideband wireless communication ... -
A character-based analysis of impacts of dialects on end-to-end Norwegian ASR
(Chapter, 2023)We present a method for analyzing character errors for use with character-based, end-to-end ASR systems, as used herein for investigating dialectal speech. As end-to-end systems are able to produce novel spellings, there ... -
Characterization and Signal Processing of Mach-Zehnder Assisted Ring Resonator Configuration Sensors
(Master thesis, 2022)Bruken av nanofotonikk i anvendelsen av biosensorer er et tverrfaglig vitenskapsområde som har tiltrukket mye oppmerksomhet, samt utviklet seg hurtig i senere år. Muligheten å integrere flere fotoniske strukturer på en ... -
Characterization of biological tissue using statistical and physics-based hyperspectral image processing methods
(Doctoral theses at NTNU;2018:402, Doctoral thesis, 2018) -
Characterization of medical piezoelectric ultrasound transducers using pulse echo methods.
(Master thesis, 2007)In this thesis, a measurement set-up has been developed to characterize high frequency medical ultrasound transducers using a pulse echo set-up. This work is a continuation of an earlier project. The aim of this project ... -
Characterization of Power Amplifiers by means of nonlinear Models with Memory
(Master thesis, 2008)Wireless communication systems suffer a great deal from the inherent nonlinear nature of power amplifiers. Effects such as signal distortion and spectral broadening can seriously degrade the performance of both the system ... -
Characterization of Solar Cell Wafers with Low Coherence Interferometry
(Master thesis, 2011)Characterize silicon wafers used in solar cell production with a NIR-LCI interferometer. The interferometer is further developed and measurements on silicon samples are carried out. -
Characterization of the Body-to-Body Propagation Channel for Subjects during Sports Activities
(Journal article; Peer reviewed, 2018)Body-to-body wireless networks (BBWNs) have great potential to find applications in team sports activities among others. However, successful design of such systems requires great understanding of the communication channel ... -
Characterizing the acoustic properties of the cavity cloud generated close to an air-gun array as a time-dependent effective medium
(Journal article, 2018)A ghost cavity cloud consists of many small vapour cavities and appears above and around the air-guns in the source array a few milliseconds after the source is fired. Since there are dissolved gases and stable microbubbles ... -
Chasing the bird: 3D acoustic tracking of aerial flight displays with a minimal planar microphone array
(Peer reviewed; Journal article, 2023)Tracking the flight patterns of birds and bats in three-dimensional space is central to key questions in evolutionary ecology but remains a difficult technical challenge. For example, complex aerial flight displays are ... -
Checking of Nanoscale Transistor Models
(Master thesis, 2016)A device compact model is a mathematical description of a device, e.g. a transistor, in an integrated circuit. Compact models are designed to be a part of a larger simulation, and work together with a circuit model. For ... -
Child Speech Recognition
(Master thesis, 2021)Talegjenkjenning for barn er utfordrende ettersom dagens talegjenkjenningssystem er basert på tale fra voksne. Talegjenkjenning kan hjelpe utviklingen av tale og språk hos barn. Derfor er det viktig å forbedre talegjenkj ... -
Chlorophyll fluorescence emission spectroscopy of oxygenic organisms at 77 K
(Journal article; Peer reviewed, 2018)Photosynthetic fluorescence emission spectra measurement at the temperature of 77 K (–196°C) is an often-used technique in photosynthesis research. At low temperature, biochemical and physiological processes that modulate ... -
CityMob: Prototype Development of a Commercial City Information Portal for Mobile Phones
(Master thesis, 2007)The extensive list of cultural offerings in big European cities has resulted in a variety of city guides in magazines and on the Internet. However, users often require information when they are on the run. A city guide ... -
Classification of Kidney Tumor Grading on Preoperative Computed Tomography Scans
