Analysis and Assessment of Onshore and Offshore Wind Turbines Failures
(Peer reviewed; Journal article, 2023)The rapidly increasing energy demand and the inevitable negative effects on the environment caused by fossil-fuelled energy production have made renewable energy technologies increasingly important and preferred among the ... -
Analysis of deceptive data attacks with adversarial machine learning for solar photovoltaic power generation forecasting
(Peer reviewed; Journal article, 2022)The solar photovoltaics (PV) energy resources have become more important with their significant contribution to the current power grid among renewable energy resources. However, the integration of the solar PV causes ... -
Analysis of filtering techniques for investigating landslide-induced topographic changes in the Oetz Valley (Tyrol, Austria)
(Peer reviewed; Journal article, 2020)Landslides endanger settlements and infrastructure in mountain areas across the world. Monitoring of landslides is therefore essential in order to understand and possibly predict their behavior and potential danger. ... -
Analysis of Machine Learning Based Imputation of Missing Data
(Peer reviewed; Journal article, 2023)Data analysis and classification can be affected by the availability of missing data in datasets. To deal with missing data, either deletion- or imputation-based methods are used that result in the reduction of data records ... -
Analysis of nonlinear effects in fluid flows through porous media
(Peer reviewed; Journal article, 2022-01)This article examines the nonlinear effects of fluid flow in a porous medium, governed by a new semi-analytical equation, from three aspects: equation derivation, experimental verification, and macroscale simulation ... -
Analysis of samples of high explosives extracted from explosive remnants of war
(Peer reviewed; Journal article, 2022)Millions of tonnes of dumped ammunition and explosive remnants of war remain in nature both on land and at sea. It is well known that the ordnance could represent a definite explosive risk if disturbed, and that some of ... -
Analysis of spar and semi-submersible floating wind concepts with respect to human exposure to motion during maintenance operations
(Peer reviewed; Journal article, 2022)Floating offshore wind turbines (FOWTs) are expected to experience onsite maintenances and inspections during their lifetimes. To carry out offshore maintenance activities, a crew will be transferred to an FOWT and spend ... -
Analysis of Thermomechanical Cracks of Disc Brake Used in Heavy Trucks
(Peer reviewed; Journal article, 2022)In the present work, the study of fatigue failure of the disc brake of Volvo truck under thermomechanical effects across the disc thickness is reported. Both analytical and numerical approaches have been used. In the ... -
Analytic structure of nonhydrodynamic modes in kinetic theory
(Peer reviewed; Journal article, 2019-09)How physical systems approach hydrodynamic behavior is governed by the decay of nonhydrodynamic modes. Here, we start from a relativistic kinetic theory that encodes relaxation mechanisms governed by different timescales ... -
Analytical modeling and correction of steady state relative permeability experiments with capillary end effects – An improved intercept method, scaling and general capillary numbers
(Peer reviewed; Journal article, 2021)Steady state relative permeability experiments are performed by co-injection of two fluids through core plug samples. Effective relative permeabilities can be calculated from the stabilized pressure drop using Darcy’s law ... -

Analytical solutions for forced and spontaneous imbibition accounting for viscous coupling
(Journal article; Peer reviewed, 2019-11-22)Fluid-fluid momentum transfer can cause higher flow resistance when fluids flow in opposite directions as compared to the same direction. Conventional modelling of flow in porous media using simple, saturation dependent relative ... -
An Analytical TOOLBOX for the Characterization of Chalks and Other Fine-Grained Rock Types within Enhanced Oil Recovery Research and Its Application—A Guideline
(Peer reviewed; Journal article, 2022-06)Analyses of fine-grained rocks like shales, cherts, and specifically chalk are challenging with regards to spatial resolution. We propose a “toolbox” to understand mineralogical alteration in chalk, especially those induced ... -
Annotation Markers for runtime replication protocol selection
(Journal article; Peer reviewed, 2008)This paper presents an architecture enabling developers to easily and flexibly assign replication protocols simply by annotating individual server methods. This avoids using costly replication protocols for all object ... -
Annular frictional pressure losses for drilling fluids
(Peer reviewed; Journal article, 2020)In the paper it is demonstrated how a Herschel-Bulkley fluid model, where the parameters are selected from relevant shear rate range of the flow and are parametrically independent, can be used for pressure loss calculations. ... -

Anomalous electrodynamics of neutral pion matter in strong magnetic fields
(Journal article; Peer reviewed, 2017-03)The ground state of quantum chromodynamics in sufficiently strong external magnetic fields and at moderate baryon chemical potential is a chiral soliton lattice (CSL) of neutral pions [1]. We investigate the interplay ... -
Anomalous low-temperature thermodynamics of QCD in strong magnetic fields
(Journal article; Peer reviewed, 2017-11)The thermodynamics of quantum chromodynamics at low temperatures and in sufficiently strong magnetic fields is governed by neutral pions. We analyze the interacting system of neutral pions and photons at zero baryon chemical ... -
Anomaly-Induced Inhomogeneous Phase in Quark Matter without the Sign Problem
(Peer reviewed; Journal article, 2019)We demonstrate the existence of an anomaly-induced inhomogeneous phase in a class of vectorlike gauge theories without the sign problem, thus disproving the long-standing conjecture that the absence of the sign problem ... -
Antiscaling Evaluation and Quantum Chemical Studies of Nitrogen-Free Organophosphorus Compounds for Oilfield Scale Management
