Numerical modelling of erosion and sedimentation around offshore pipelines [PDF]

open access: yes, 1990
In this paper a numerical model is presented for the description of the erosion and sedimentation near pipelines on the sea bottom. The model is based on the Navier-Stokes equations and the equation of motion and continuity of sediment.\ud \ud The ...

‘Wind, Wind, Wind, Always Winding Am I’: Dickens’s Metafictional Clockwork

open access: yesThe Review of English Studies, 2022
Abstract This article considers the importance of timepieces and clockwork to Dickens’s conception of composition. Whilst the many clocks and watches that saturate his writing have often been read as indicative of an interest in time, the present study considers what the materiality of timepieces—namely, their markets and mechanisms ...

Performance of superconducting generators with different topologies under fault conditions

open access: yesThe Journal of Engineering, 2019
This paper compares the short-circuit performance of superconducting (SC) generators with three different topologies, i.e. iron-cored stator and rotor, iron-cored stator and air-cored rotor, and air-cored stator and rotor.

Wind Winding Down [PDF]

open access: yesScience, 2011
Climate Science Increasing concentrations of greenhouse gases in the atmosphere, emitted by human activities, have caused Earth's climate to warm. Climate warming has been linked to a host of other environmental changes, one of the most evident being an increase in the amount of water present ...

An analytical model of crenulate shaped beaches [PDF]

open access: yes, 1994
An analytical model for the development of crenulate shaped beaches is constructed. It is assumed that the shape of the crenulate shaped beach remains constant with time and expands with a rate according to a time function. Based upon a sediment balance,

Wissensbearbeitung im Produktionsprozess des zeitgenössischen Dokumentartheaters

open access: yesStudia theodisca, 2016
Documentary theatre aims to portray truth or authenticity. It tries to produce knowledge, though it is rather difficult to assert the authenticity of this knowledge because the sources imply a great deal of subjectivity.
