Design of mine dynamic imaging transient electromagnetic instrument

open access: yesMeikuang Anquan, 2022
A new downhole dynamic imaging transient electromagnetic instrument is designed. The transmitter of transient electromagnetic instrument adopts six field effect tubes to form a fast shutdown bridge.

Challenges in predicting Greenland supraglacial lake drainages at the regional scale [PDF]

open access: yesThe Cryosphere, 2021
A leading hypothesis for the mechanism of fast supraglacial lake drainages is that transient extensional stresses briefly allow crevassing in otherwise compressional ice flow regimes.

Fast evaluation of transient acoustic fields [PDF]

open access: yesThe Journal of the Acoustical Society of America, 2016
The efficient computation of transient fields radiated by non-harmonic source distributions is a problem relevant in numerous areas of acoustics. This paper presents an efficient easily implemented method for the generation of time-dependent spherical harmonic expansions for arbitrary sources, which can be used to compute the transient radiated field ...

Real-Time HIL Emulation of DRM With Machine Learning Accelerated WBG Device Models

open access: yesIEEE Open Journal of Power Electronics, 2023
The proliferation of artificial intelligence (AI) has opened up new avenues for the modeling of power electronics with ultra-fast transient responses, such as wide-bandgap (WBG) devices.

Pulsars and Fast Transients with LOFAR

open access: yesAIP Conference Proceedings, 2011
The LOw Frequency ARray is the first of the next generation of radio telescopes to be completed. It uses large numbers of small receptors and vast computing and data transport capabilities to achieve a high degree of sensitivity over large fields of view.

Reactor behavior comparisons for two liquid metal-cooled fast reactors during an event of loss of coolant

open access: yesCase Studies in Thermal Engineering, 2019
The aim of this paper is to present a fast-numerical tool based on the average channel approach to analyze the response of fast reactors under unprotected loss of flow events.

Exploiting the dynamic properties of FET-based chemical sensors [PDF]

open access: yes, 1989
After a long period of mainly static application of ISFETS, other more sophisticated applications are being developed, based on the exploitation of the dynamic properties of ISFETS. Examples are the use of flow-through cells with sample injection and the

Fast transients in complex pneumatic circuits

open access: yesProceedings of the JFPS International Symposium on Fluid Power, 1993
Fast transients in pneumatic circuits occur frequently (e.g. braking plants, active suspensions, fast actuation of cylinders etc.). Required accuracy in the hundredth of second range can be obtained by simulation, through exact identification of component behaviour and propagative effects.

How to achieve fast entrainment? The timescale to synchronization. [PDF]

open access: yesPLoS ONE, 2009
Entrainment, where oscillators synchronize to an external signal, is ubiquitous in nature. The transient time leading to entrainment plays a major role in many biological processes.

Enabling pulsar and fast transient searches using coherent dedispersion

open access: yes, 2016
We present an implementation of the coherent dedispersion algorithm capable of dedispersing high-time-resolution radio observations to many different dispersion measures (DMs).
