On isotropic turbulence in the dark fluid universe
(Journal article; Peer reviewed, 2011)As a first part of this work, experimental information about the decay of isotropic turbulence in ordinary hydrodynamics, is used as input in FRW equations in order to investigate how an initial fraction f of turbulent ... -
On Kalman filtering with linear state equality constraints
(Journal article; Peer reviewed, 2019)This article is concerned with the state estimation problem for linear systems with linear state equality constraints. We re-examine constrained Kalman filter variations and propose an alternative derivation of the optimal ... -
On Large Local Error Accumulation in Multilevel Error Diffusion
(Journal article; Peer reviewed, 2016)Error diffusion is an often used method that transforms a continuous tone (multibit) image into an image of lower bit depth, most commonly into a binary output of black and white. The simplicity of the processing and the ... -
On lax transformations, adjunctions, and monads in (∞,2)-categories
(Peer reviewed; Journal article, 2021)We use the basic expected properties of the Gray tensor product of (∞, 2)-categories to study (co)lax natural transformations. Using results of Riehl–Verity and Zaganidis we identify lax transformations between adjunctions ... -
On Linking of Task Analysis in the HRA Procedure: The Case of HRA in Offshore Drilling Activities
(Journal article; Peer reviewed, 2018)Human reliability analysis (HRA) has become an increasingly important element in many industries for the purpose of risk management and major accident prevention; for example, recently to perform and maintain probabilistic ... -
On local isometric immersions into complex and quaternionic projective spaces
(Peer reviewed; Journal article, 2011)We will prove that if an open subset of CPn is isometrically immersed into CPm, with m < (4/3)n−2/3, then the image is totally geodesic.We will also prove that if an open subset of HPn isometrically immersed into HPm, with ... -
On long-term fatigue damage and reliability analysis of gears under wind loads in offshore wind turbine drivetrains
(Journal article; Peer reviewed, 2014)In this paper, a long-term fatigue damage analysis method for gear tooth root bending in wind turbine’s drivetrains is presented. The proposed method is established based on the ISO gear design codes which are basically ... -
On low frequencies emitted by air guns at very shallow depths - An experimental study
(Journal article; Peer reviewed, 2019)In marine seismic acquisition, the enhancement of frequency amplitudes below 5 Hz is of special interest because it improves imaging of the subsurface. The frequency content of the air gun, the most commonly used marine ... -
On Low-Cost Privacy Exposure Attacks in LTE Mobile Communication
(Journal article; Peer reviewed, 2017)Abstract The security of mobile communication is of great interest nowadays because of the wide spread and extensive use of mobile communication worldwide. Although LTE has been designed to provide better security than ... -
On Lower Bounds for Maximin Share Guarantees
(Chapter, 2023)We study the problem of fairly allocating a set of indivisible items to a set of agents with additive valuations. Recently, Feige et al. (WINE'21) proved that a maximin share (MMS) allocation exists for all instances with ... -
On Mathematical Analysis of Active Drug Transport Coupled with Flow-induced Diffusion in Blood Vessels
(Peer reviewed; Journal article, 2021)Blood vessels are flow-induced diffusive molecular channels equipped with transport mechanisms across their walls for conveying substances between the organs in the body. Mathematical modeling of the blood vessel as a ... -
On Model Predictive Path Following and Trajectory Tracking for Industrial Robots
(Journal article; Peer reviewed, 2017)In this article the model predictive path following controller and the model predictive trajectory tracking con-troller are compared for a robotic manipulator. We consider both the Runge-Kutta and collocation based ... -
On model-based system approach for health monitoring of drivetrains in floating wind turbines
(Journal article; Peer reviewed, 2017)This paper deals with the health monitoring of a wind turbine drivetrain in a system perspective. A 5-MW reference drivetrain installed on a spar type floating wind turbine is selected. Degradation and damage in the main ... -
On Modeling Eavesdropping Attacs in Underwater Acoustic Sensor Networks
(Journal article; Peer reviewed, 2016)The security and privacy of underwater acoustic sensor networks has received extensive attention recently due to the proliferation of underwater activities. This paper proposes an analytical model to investigate the ... -
On modelling electrochemical gas evolution using the volume of fluid method
(Chapter, 2020)In this work we describe the various building block relevant in simulating electrochemical gas evolution using Volume of Fluid (VOF) method. These building blocks are implemented in the VOF solver available in OpenFOAM® ... -
On modelling of anisotropic undrained strength for non-horizontal terrain
(Chapter, 2018)Low plasticity soft clays show pronounced variation in undrained shear strength with the direction of loading. The active undrained shear strength (A) is significantly larger than the direct shear strength (D), which again ... -
On Monolithic and Microservice deployment of Network Functions
(Chapter, 2019)Network Function Virtualization (NFV) has recently attracted telecom operators to migrate network functionalities from expensive bespoke hardware systems to virtualized IT infrastructures where they are deployed as software ... -
On Montgomery's pair correlation conjecture: A tale of three integrals
(Peer reviewed; Journal article, 2022)We study three integrals related to the celebrated pair correlation conjecture of H. L. Montgomery. The first is the integral of Montgomery’s function F(α,T) in bounded intervals, the second is an integral introduced by ... -
