Foundations of offshore wind turbines: A review
(Journal article; Peer reviewed, 2019)Offshore wind is a source of clean, renewable energy of great potential value to the power industry in the context of a low carbon society. Rapid development of offshore wind energy depends on a good understanding of ... -
Four decades of Brazilian and international research on street children: A meta-narrative review
(Peer reviewed; Journal article, 2021)The last 40 years has yielded a vast body of literature on street children. In this article, we reflect on the knowledge accumulated by several generations of scholars and across two bodies of research. The article’s aim ... -
Four definitions of magnetic permeability for periodic metamaterials
(Journal article; Peer reviewed, 2019)We state and compare four different definitions of magnetic permeability for periodic, artificial media, or metamaterials. The connections among them, and properties in general, are discussed in detail, including causality, ... -
Four Degree-of-Freedom Hydrodynamic Maneuvering Model of a Small Azipod-Actuated Ship With Application to Onboard Decision Support Systems
(Peer reviewed; Journal article, 2023)The main contribution of this paper is a numerical ship motion model of NTNU’s research vessel Gunnerus, capturing the surge, sway, roll, and yaw dynamics when sailing in uniform and steady currents. The model utilizes a ... -
Four Level Voltage Active Gate Driver for Loss and Slope Control in SiC MOSFETs
(Journal article, 2022)Silicon Carbide power semiconductors exhibit fast dynamic behavior. This facilitates the design of high efficiency and high power density converters. However, the resulting current and voltage changing rates demand extensive ... -
Four new suomilides isolated from the cyanobacterium Nostoc sp. KVJ20 and proposal of their biosynthetic origin
(Peer reviewed; Journal article, 2023)The suomilide and the banyasides are highly modified and functionalized non-ribosomal peptides produced by cyanobacteria of the order Nostocales. These compound classes share several substructures, including a complex ... -
Four tragedies and a happy ending – autobiographical interpretations of unemployment
(Peer reviewed; Journal article, 2014)This article explores individuals' experience of unemployment by studying five historical autobiographical stories. A source of life-stories from the competition ‘Write your life’ in 1989 was read through in search of ... -
Four-point transient potential drop measurements on metal plates
(Journal article; Peer reviewed, 2020)The transient potential drop method is based on measurement of the transient voltage on the surface of a conductor due to the injection of a pulsed current. In this paper, we consider an approximate analytical model for ... -
Four-wave Mixing-based Wavelength Conversion and Parametric Amplification in Submicron Silicon Core Fibers
(Peer reviewed; Journal article, 2020)Silicon core fibers represent a versatile platform for all-fiber integrated nonlinear optical applications. This paper describes the state of the art in four-wave mixing-based parametric amplification, and wavelength ... -
Fourier Interpolation and Time-Frequency Localization
(Peer reviewed; Journal article, 2021)We prove that under very mild conditions for any interpolation formula f(x)=∑λ∈Λf(λ)aλ(x)+∑μ∈Mf^(μ)bμ(x) we have a lower bound for the counting functions nΛ(R1)+nM(R2)≥4R1R2−Clog2(4R1R2) which very closely matches recent ... -
Fourier Interpolation with Zeros of Zeta and L-Functions
(Peer reviewed; Journal article, 2022)We construct a large family of Fourier interpolation bases for functions analytic in a strip symmetric about the real line. Interesting examples involve the nontrivial zeros of the Riemann zeta function and other L-functions. ... -
Fourier optimization and quadratic forms
(Peer reviewed; Journal article, 2021)We prove several results about integers represented by positive definite quadratic forms, using a Fourier analysis approach. In particular, for an integer ℓ≥1, we improve the error term in the partial sums of the number ... -
Fourier ptychography algorithm based on scaled Fourier transform
(Peer reviewed; Journal article, 2021)This letter discusses an alternative Fourier ptychography algorithm based on the scaled fast Fourier transform propagation. The advantage of this scheme is that it enables a zoom-in capability of the object spectrum and ... -
Fourier Transform Infrared Radiation Spectroscopy Applied for Wood Rot Decay and Mould Fungi Growth Detection
(Journal article; Peer reviewed, 2012)Material characterization may be carried out by the attenuated total reflectance (ATR) Fourier transform infrared (FTIR) radiation spectroscopical technique, which represents a powerful experimental tool. The ATR technique ... -
Fourier transform-based method for quantifying the three-dimensional orientation distribution of fibrous units
(Peer reviewed; Journal article, 2024)Several materials and tissues are characterized by a microstructure composed of fibrous units embedded in a ground matrix. In this paper, a novel three-dimensional (3D) Fourier transform-based method for quantifying the ... -
Fourier-based effective permeability for transformer iron losses computation under saturation
(Journal article; Peer reviewed, 2020)Computation of iron losses in transformers requires significant numerical efforts, particularly under magnetic saturation when the magnetic non-linearity needs to be considered. This study proposes a Fourier method to ... -
