Fractal and multifractal analysis of PET/CT images of metastatic melanoma before and after treatment with ipilimumab
(Peer reviewed; Journal article, 2016)Background PET/CT with F-18-fluorodeoxyglucose (FDG) images of patients suffering from metastatic melanoma have been analysed using fractal and multifractal analysis to assess the impact of monoclonal antibody ipilimumab ... -
Fractal modelling of turbulent flows: Subgrid modelling for the Burgers equation
(Master thesis, 2011)The stochastically forced Burgers equation shares some of the same characteristics as the three-dimensional Navier-Stokes equations. Because of this it is sometimes used as a model equation for turbulence. Simulating the ... -
A fractal uncertainty principle for the short-time Fourier transform and Gabor multipliers
(Peer reviewed; Journal article, 2023)We study the fractal uncertainty principle in the joint time-frequency representation, and we prove a version for the Short-Time Fourier transform with Gaussian window on the modulation spaces. This can equivalently be ... -
Fractal-Like Flow-Fields with Minimum Entropy Production for Polymer Electrolyte Membrane Fuel Cells

Fractional anisotropy in frontotemporal association tracts is related to spatial aspects of episodic memory performance: a dMRI study
(Master thesis, 2020)The representation of time and space in the human brain reflects intuitive, yet complex dimensions that are difficultly measured. The study of spatial representation in the brain is perhaps most commonly associated with ... -
Fractional exhaled nitric oxide as a potential biomarker for radiation pneumonitis in patients with non-small cell lung cancer: A pilot study
(Peer reviewed; Journal article, 2019)Introduction The aim of the study was to investigate repetitive fractional exhaled nitric oxide (FeNO) measurements during high-dose radiation therapy (HDRT) and to evaluate the use of FeNO to predict symptomatic radiation ... -
Fractional stability of trunk acceleration dynamics of daily-life walking: toward a unified concept of gait stability
(Journal article; Peer reviewed, 2017)Over the last decades, various measures have been introduced to assess stability during walking. All of these measures assume that gait stability may be equated with exponential stability, where dynamic stability is ... -
Fractional-n Frequency Synthesis
(Master thesis, 2006)A high level model of a fractional-n frequency synthesizer has been created in VHDLAMS, and simulations shows that the system works as intended. A voltage controlled oscillator has been designed at transistor level, and ... -
Fractional-order Control: Nyquist Constrained Optimization
(Peer reviewed; Journal article, 2020)The adoption of fractional calculus in control systems has enabled the synthesis of new controllers with fractional-order derivatives and integrals. Several optimization-based methods for tuning of linear fractional-order ... -
Fractional-order correntropy adaptive filters for distributed processing of alpha-stable signals
(Peer reviewed; Journal article, 2020)This work revisits the problem of distributed adaptive filtering in multi-agent sensor networks. In contrast to classical approaches, the formulation relaxes the Gaussian assumption on the signal and noise to the generalized ... -
Fractional-Order Correntropy Adaptive Filters for Distributed Processing of α -Stable Signals
(Journal article; Peer reviewed, 2020)This work revisits the problem of distributed adaptive filtering in multi-agent sensor networks. In contrast to classical approaches, the formulation relaxes the Gaussian assumption on the signal and noise to the generalized ... -
Fractional-order correntropy filters for tracking dynamic systems in alpha-stable environments
(Peer reviewed; Journal article, 2020)In an increasing number of modern filtering applications, the encountered signals consist of frequent sharp spikes, that cannot be accurately modeled using Gaussian random processes. Modeling the behavior of such signals ... -
Fractionation of Transition Metals by Solvent Extraction and Precipitation from Tannic Acid-Acetic Acid Leachate as a Product of Lithium-Ion Battery Leaching
(Peer reviewed; Journal article, 2022)Solvent extraction and precipitation schemes are applied to isolate copper, cobalt, manganese and nickel from leachate, produced from spent lithium-ion battery leaching using tannic acid-acetic acid as lixiviant. The metal ... -
