Analyzing and modeling sub-diffusive transport of bedload along a heterogeneous gravel bed using stochastic and statistical methods

Zhenzhu Meng, Zhipeng Li, Yong Zhang

Bedload transport is one of the main mechanisms for sediment transport in rivers. Bedload transport may exhibit anomalous dispersion behavior during the formation of clusters on the surface of a heterogeneous river bed, which cannot be quantified by the cl ...

Comparing re-balancing and diusion behavior between docked and dock-less bike-sharing systems

Arisen with the complexity of the systems. Two distinct BSS types can be identifed: Docked and Dock-less. This study focuses on comparing re-balancing and diffusion behavior between Divvy's docked BSS in Chicago and Mobike's dock-less BSS in Chengdu, China ...

Compact Model for Continuous Microfluidic Mixer

Jean-Michel Sallese, Christophe Lallement

While the development of lab-on-chip is increasing, the lack of dedicated computer-aided design tools appears as a bottleneck preventing the emergence of large-scale industrial applications. One of the answer relied on 50 years of CAD experience in microel ...

Guanidinium-Assisted Surface Matrix Engineering for Highly Efficient Perovskite Quantum Dot Photovoltaics

Shaik Mohammed Zakeeruddin, Xiaoyu Zhang, Jiabao Yang, Chunyang Zhang, Xufeng Ling, Wanli Ma

Metal halide perovskite quantum dots (Pe-QDs) are of great interest in new-generation photovoltaics (PVs). However, it remains challenging in the construction of conductive and intact Pe-QD films to maximize their functionality. Herein, a ligand-assisted s ...

Anomalous Nernst effect in Co2MnGa thin films with perpendicular magnetic anisotropy

Jean-Philippe Ansermet, Haiming Yu, Simon Granville, Sa Tu, Junfeng Hu, Yao Zhang, Song Liu

The thermoelectric and transport properties of MgO/Co2MnGa/Pd stacks with perpendicular magnetic anisotropy were measured. For a nominal 3.3 nm Co2MnGa thickness, the anomalous Nernst coefficient and the Nernst angle at room temperature were found to be 0. ...

MATHICSE Technical Report : A posteriori error analysis of a local adaptive discontinuous Galerkin method for convection-diffusion-reaction equations

Giacomo Rosilho De Souza

A local adaptive discontinuous Galerkin method for convection-diffusion-reaction equations is introduced. Departing from classical adaptive algorithms, the proposed method is based on a coarse grid and iteratively improves the accuracy of the solution by s ...
