Pied-piping in wh-questions:What do children say about it? [PDF]

open access: yes, 2011
Errors/non-target responses characterizing sub-extraction of a wh-phrase from complex DPs in child speech are found in first language acquisition studies (van Kampen 1997 among others) and have provided the basis for arguing the complexity of question ...

Characterization of the Erosion Damage Mechanism of Coal Gangue Slopes through Rainwater Using a 3D Discrete Element Method: A Case Study of the Guizhou Coal Gangue Slope (Southwestern China)

open access: yesApplied Sciences, 2022
Coal gangue is one of the largest solid wastes in the world. In previous studies, the influence and mechanisms of rainfall infiltration on coal gangue slope stability and possible rain erosion have been studied through theoretical analysis, numerical ...

Experimental Investigation on the Acoustic Scattering Matrix for a Centrifugal Pump

open access: yesProceedings, 2018
Fluid-dynamic noise in centrifugal pumps as a significant sound source in piping systems has gained high attention due to the requirements of vibration and noise reduction in many fields. The acoustic characteristics of the fluid-dynamic noise from pumps

Evaluation of the effects of a load shedding at a lignite power plant

open access: yesEnergy Science & Engineering, 2021
The load‐shedding scenario describes an unscheduled load reduction in a power plant so that it produces only the electricity that is needed by the plant itself. The reason for such a scenario is a collapse of power supply in the transmission network.

Influence of Particle Mass Fraction over the Turbulent Behaviour of an Incompressible Particle-Laden Flow

open access: yesFluids, 2021
The presence of spherical solid particles immersed in an incompressible turbulent flow was numerically investigated from the perspective of the particle mass fraction (PMF or ϕm), a measure of the particle-to-fluid mass ratio.

Robust decentralized model predictive control approach for a multi-compressor system surge instability including piping acoustic

open access: yesCogent Engineering, 2018
One of the major problems in modern gas compressing stations is related to surge control of compression system with multi-compressor. Due to the coupled system dynamics, standard controllers can interfere with each unit′s performance.

Investigations of the Formation Mechanism and Pressure Pulsation Characteristics of Pipeline Gas-Liquid Slug Flows

open access: yesJournal of Marine Science and Engineering
The pipeline system is widely used in marine engineering, and the formation mechanism and flow patterns of two-phase slug flows are of great significance for the optimal design of and vibration prevention in a complex pipeline system. Aiming at the above
