COMSOL_PHREEQC is a software tool that couples the generic finite element solver COMSOL Multiphysics® with the geochemical modeling framework PHREEQC to simulate a wide variety of environmental flow and transport processes (COMSOL) together with comprehens ...
In this paper, we present an experimental study about the motion of bed load particles in water. Recent developments in the stochastic theory of bed load transport call for precise experimental data to validate the models. We set up the experiment in a til ...
The concept of passenger air transport has not changed since its beginning. However it has to transport more and more people. Clip-Air provides a revolutionary concept for air transport by carrying up to three capsules (about an A320 without wings and tail ...
The internal transport and recombination parameters of solid-state dye-sensitized solar cells (ssDSCs) using the amorphous organic semiconductor 2,2',7,7'-tetrakis(N,N-di-p-methoxyphenylamine)-9,9'-spirobtfluorene (spiro-MeOTAD) as a hole transport materia ...
A simple and general fabrication method for helical swimming micromachines by direct laser writing and e-beam evaporation is demonstrated. The magnetic helical devices exhibit varying magnetic shape anisotropy, yet always generate corkscrew motion using a ...
The bedload transport rate is of large fluctuation across several time scales. Understanding bedload transport fluctuation would be helpful for modeling the transport process. In this talk, we first report a multi-scale phenomenon of fluctuation of bedload ...
This paper proposes a probabilistic method that infers the transport modes and the physical path of trips from smartphone data that were recorded during travels. This method synthesizes multiple kinds of data from smartphone sensors which provide relevant ...
In this paper we show that individual attitudes of road carriers and their latent preferences toward specific freight service attributes do play a role in determining their mode choices. Specifically, we contribute to the empirical literature on freight ag ...
This paper provides orders of magnitude of the importance of CO2 emissions from international transport freight activities under a variety of scenarios regarding trade and climate policies. It is based on a stylized multi-region, multi-sector CGE model tha ...
Travel times are fundamental catchment descriptors that blend key information about storage, geochemistry, flow pathways and sources of water into a coherent mathematical framework. Here we analyze travel time distributions (TTDs) (and related attributes) ...
