Wind power forecasting – A data-driven method along with gated recurrent neural network

open access: yes, 2021
Effective wind power prediction will facilitate the world’s long-term goal in sustainable development. However, a drawback of wind as an energy source lies in its high variability, resulting in a challenging study in wind power forecasting. To solve this

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,

Wind field reconstruction from nacelle-mounted lidar short-range measurements [PDF]

open access: yesWind Energy Science, 2017
Profiling nacelle lidars probe the wind at several heights and several distances upstream of the rotor. The development of such lidar systems is relatively recent, and it is still unclear how to condense the lidar raw measurements into useful wind ...

‘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.
