Elucidating spatial heterogeneities in 3D printed thermoplastic elastomers using micro-beam small-angle x-ray scattering [PDF]

open access: yesStructural Dynamics
3D printing is uniquely capable of producing architectures with hierarchically ordered structure from the nano-scale through the macro-scale (cm). One primary approach by which 3D printing can tune nano- and meso-scale material anisotropy is through the ...

Effect of Intake Particle Dimension and Grain Size on Discharge Coefficient in Porous Bottom Intakes Using Physical Modeling [PDF]

open access: yesعلوم و مهندسی آبیاری, 2018
Water intake from the river is done using several methods. Each method has its own features and limitations. In steep mountain rivers with irregular bed, high values of sediment transport and flash floods may prevent the application of gated dams ...

Impacts of Evaporation‐Induced Groundwater Upwelling on Mixing Dynamics in Shallow Wetlands

open access: yesGeophysical Research Letters, 2023
Groundwater mixing dynamics play a crucial role in the biogeochemical cycling of shallow wetlands. In this paper, we conducted groundwater simulations to investigate the combined effects of evaporation and local heterogeneity on mixing dynamics in ...

CFD analysis and flow model reduction for surfactant production in helix reactor [PDF]

open access: yesChemical Industry and Chemical Engineering Quarterly, 2015
Flow pattern analysis in a spiral Helix reactor is conducted, for the application in the commercial surfactant production. Step change response curves (SCR) were obtained from numerical tracer experiments by three-dimensional computational fluid

Optical flow in the presence of spatially-varying motion blur [PDF]

open access: yes2012 IEEE Conference on Computer Vision and Pattern Recognition, 2012
This paper extends the classical warping-based optical flow method to achieve accurate flow in the presence of spatially-varying motion blur. Our idea is to parameterize the appearance of each frame as a function of both the pixel motion and the motion-induced blur.

A method for parameterising roughness and topographic sub-grid scale effects in hydraulic modelling from LiDAR data [PDF]

open access: yesHydrology and Earth System Sciences, 2010
High resolution airborne laser data provide new ways to explore the role of topographic complexity in hydraulic modelling parameterisation, taking into account the scale-dependency between roughness and topography.

Characteristics of the natural flow regime paradigm explain occurrence of imperiled Great Plains fishes

open access: yesEcosphere, 2021
The natural flow regime (NFR) paradigm posits that naturally occurring temporal fluctuations in streamflow are necessary for maintaining natural ecological communities.

Kinematic reverse flood routing in natural rivers using stage data

open access: yesApplied Water Science, 2022
In many developing countries, due to economic constraints, a single station on a river reach is often equipped to record flow variables. On the other hand, hydrographs at the upstream sections may also be needed for especially assessing flooded areas ...

Distribution characteristics of phosphorus in the sediments and overlying water of Poyang lake. [PDF]

open access: yesPLoS ONE, 2015
Phosphorus (P) is a key indicator of the aquatic organism growth and eutrophication in lakes. The distribution and speciation of P and its release characteristics from sediments were investigated by analyzing sediment and water samples collected during ...

Controlling Droplet Marangoni Flows to Improve Microscopy-Based TB Diagnosis

open access: yesDiagnostics, 2021
In developing countries, the most common diagnostic method for tuberculosis (TB) is microscopic examination sputum smears. Current assessment requires time-intensive inspection across the microscope slide area, and this contributes to its poor diagnostic
