Modal sound propagation in curved horns of rectangular cross-section
(Master thesis, 2013)Wave propagation in horns can be simulated by propagating both the plane wave component and the higher order modes down the horn, as described by Kemp (2002). While this is most common for axisymmetric ducts, the method ... -
Model based estimation of speckle filter for improved suppression of multiple scattering noise with dual band ultrasound pulse complexes
(Master thesis, 2015)In ultrasound imaging, multiple scattering noise can be severely damaging to the image quality. SURF imaging is a non-linear imaging method that can be used to suppress the multiple scattering noise, and thus improve the ... -
Model based estimation of the complex material constants for thickness extension and radial mode in an ultrasound disk transducer
(Master thesis, 2012)The main goal of this thesis is to establish a method and estimate the complex materialconstants for the radial and thickness mode. This has been done in two separate methods. For the thickness mode material constants, a ... -
Model predictive control for a multi-body slung-load system
(Journal article; Peer reviewed, 2017)In this paper we present a multi-level and distributed control system, based on a robust Model Predictive Control (MPC) technique, for a multi-body slung-load system. In particular, we consider a swarm of autonomous ... -
Model-Based Estimation of Seafloor Parameters by use of Acoustic Backscattering
(Dr. ingeniøravhandling, 0809-103X; 2001:62, Doctoral thesis, 2001)An algorithm for characterization of the seafloor by use of a parametric acoustic source has been developed. It is called FARIM – Frequency Analysis based Roughness and Impedance estimation method. The work was done within ... -
Modeling a Two Stage SAR-Assisted Pipeline ADC
(Master thesis, 2016)In this work, the 15-bit SAR-assisted pipeline ADC has been examined, and high-level models have been made in Cadence to verify its operation. The goal is to achieve a resolution of more than 14 ENOB at a sampling frequency ... -
Modeling and Characterization of SOI Multigate MOSFETs
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:334, Doctoral thesis, 2011)Multi-gate MOSFETs (MugFETs) with superior gate control are replacing planar CMOS in future technology nodes. Recently Intel announced that their 22nm technology will be based upon 3D Tri-gate MOSFETs. An accurate modeling ... -
Modeling and Confidence in a System for Automatic Classification of Birdsong
(Master thesis, 2015)It turns out that using a two-state-HMM model structure with appurtenant GMM-based state distributions improves the system performance compared to the use of just GMMs as model structure for each bird specie. Hence, it is ... -
Modeling and Design of a Dual-Residue Pipelined ADC in 130nm CMOS
(Master thesis, 2012)A 9-bit 50M S/s dual-residue pipelined ADC is modeled and analyzed. Thefirst stage is a modified pipelined ADC stage, while the other stages uses aninterpolator to resolve the signals, the focus is on designing these stages. ... -
Modeling and Learning Strategies for Graph Signal Processing
(Doctoral theses at NTNU;2021:253, Doctoral thesis, 2021)This thesis proposes methods for modeling and learning over graphs. In the scope of graph modeling, we first address the construction of graphs suitable for compressing images that share strong redundancy — in particular, ... -
Modeling and monitoring cerebral blood flow in premature infants with patent ductus arteriosus using ultrasound Doppler technique
(Master thesis, 2018)The aim of this thesis was to simulate cerebral bloodflow of premature infants with patent ductus arteriosus, using a lumped model. A linear Windkessel-3 model with constant peripheral resistance, and a non-linear Windkessel-3 ... -
