CPU and GPU Co-processing for Sound
(Master thesis, 2010)When using voice communications, one of the problematic phenomena that can occur, is participants hearing an echo of their own voice. Acoustic echo cancellation (AEC) is used to remove this echo, but can be computationally ... -
Cr-doped ZnS for Intermediate Band Solar Cells
(Doktoravhandlinger ved NTNU, 1503-8181; 2014:274, Doctoral thesis, 2014)Intermediate band solar cells (IBSCs) can potentially be highly efficient solar cells. This thesis presents the growth and characterization of highly doped chromium doped zinc sulfide (Cr:ZnS) films for use in IBSCs. The ... -
Cr/Fe ratio by XPS spectra of magnetoelectropolished AISI 316L SS fitted by Gaussian-Lorentzian shape lines
(Journal article; Peer reviewed, 2014)In the paper, the analyses of Fe2p3/2 and chromium Cr2p3/2 XPS spectra with fitting by symmetrical and asymmetrical line shapes, are presented. The calculations are performed on AISI 316L SS biomaterial after magnetoelec ... -
Cr4+: YAG chirped-pulse oscillator
(Journal article; Peer reviewed, 2008)We demonstrate chirped-pulse operation of a Cr :YAG passively mode-locked laser. Different operation regimes of the laser are extensively investigated in the vicinity of zero dispersion both experimentally and numerically. ... -
Cr:ZnSe Bulk and Cr:ZnSe Thin Disk cw Lasers
(Chapter, 2012)A Thulium-fiber-laser pumped Cr:ZnSe bulk cw laser with an output power of 6.5W as well as a Thulium-fiber-laser or diode-laser-stack pumped Cr:ZnSe thin disk cw laser with almost 2W of output powers will be presented. -
Cr:ZnSe thin disk cw laser
(Journal article; Peer reviewed, 2013)A Thulium fiber laser pumped or InP diode laser stack pumped Cr:ZnSe thin disk cw multimode laser at 2.4 µm with an output power of 5 and 4 W, respectively, and with optical-tooptical efficiencies of 10% will be presented. ... -
Crack characterization Field measurements
(Master thesis, 2016)The thesis examines if it is possible to use resistivity measurements done with a Wenner probe to estimate the crack depth in concrete. -
Crack Detection in Single- and Multi-Light Images of Painted Surfaces using Convolutional Neural Networks
(Chapter, 2019)Cracks represent an imminent danger for painted surfaces that needs to be alerted before degenerating into more severe aging effects, such as color loss. Automatic detection of cracks from painted surfaces' images would ... -
“Crack ends it all?” A study of the interrelations between crack cocaine, social environments, social relations, crime, and homicide among poor, young men in urban Brazil
(Journal article; Peer reviewed, 2014)In this article, actor network theory is used to explore the consumption of crack cocaine in street settings. The article is based on multiple periods of fieldwork over several years among young men in Salvador, Brazil. ... -
Crack growth in high strength mooring line steel under variable amplitude loading
(Peer reviewed; Journal article, 2024)Mooring lines are of key importance for the safe and reliable operation of numerous floating offshore structures. Due to the constantly changing wind and wave conditions acting on such structures, any fatigue crack growth ... -
Crack initiation life in notched Ti-6Al-4V titanium bars under uniaxial and multiaxial fatigue: Synthesis based on the averaged strain energy density approach
(Journal article; Peer reviewed, 2017)The fatigue behaviour of circumferentially notched specimens made of titanium alloy, Ti-6Al-4V, has been analysed. To investigate the notch effect on the fatigue strength, pure bending, pure torsion and multiaxial ... -
Crack localization and the interplay between stress enhancement and thermal noise
(Peer reviewed; Journal article, 2021)We study the competition between thermal fluctuations and stress enhancement in the failure process of a disordered system by using a local load sharing fiber bundle model. The thermal noise is introduced by defining a ... -
Crack paths in multiaxial fatigue of C45 steel specimens and correlation of lifetime with the thermal energy dissipation
(Peer reviewed; Journal article, 2022)The work reports the observed fatigue damage of C45 steel specimens tested in a previous work under multiaxial loading conditions and its relationship with the thermal energy dissipation which has been used in the last ... -
Crack propagation and arrest of structural steels and pipelines
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:105, Doctoral thesis, 2008)Crack arrest of fast running cracks is an important issue for the safety of steel structures. Crack arrest design can prevent fatal damage of large structures by restricting the influence of the incidents. Therefore crack ... -
Crack propagation in a brittle DCB specimen assessed by means of the Williams? power expansion
(Journal article; Peer reviewed, 2019)A double cantilever beam geometry has been chosen in order to investigate the importance of the higher-order terms of the Williams’ power expansion for the crack path estimation. The crack propagation has been tested ... -
