A curved flume bed-load experiment

In this report the results of a bed-load experiment in a curved flume are presented. The experiments have been carried out in the Laboratory of Fluid Mechanics (L.F.M.) at the Delft University of Technology. The main object of the experiments is to develop and to test data-acquisition procedures for future suspended-load experiments. At the same...

Suspended-load experiments in a curved flume, run no. 1

A laboratory experiment in a 180 degree curved flume with a mobile bed and suspended sediment transport is described. The flow is stationary. The main purpose of the experiment is to provide data to calibrate and test morphological models for river bend flow with suspended sediment. The bed topography is measured by means of an profile indicator...

Structure, optical absorption, and luminescence energy calculations of Ce3+ defects in LiBaF3

Ab Initio Calculations in Scintillator Research

The optical characteristics of the Ce3+ ion are largely determined by the geometry of the direct environment of the cerium-ion, and are often very sensitive to changes in this environment. These changes are for example periodic changes because of thermal movements of the atoms in the grid, but also because of static changes such as an optical...

In vivo biodistribution of stable spherical and filamentous micelles probed by high-sensitivity SPECT

Understanding how nanoparticle properties such as size, morphology and rigidity influence their circulation time and biodistribution is essential for the development of nanomedicine therapies. Herein we assess the influence of morphology on cellular internalization, in vivo biodistribution and circulation time of nanocarriers using...

The Impact of a 3-D Earth Structure on Glacial Isostatic Adjustment in Southeast Alaska Following the Little Ice Age

In Southeast Alaska, extreme uplift rates are primarily caused by glacial isostatic adjustment (GIA), as a result of ice thickness changes from the Little Ice Age to the present combined with a low-viscosity asthenosphere. Previous GIA models adopted a 1-D Earth structure. However, the actual Earth structure is likely more complex due to the...

Combine Statistical Thinking With Open Scientific Practice: A Protocol of a Bayesian Research Project

Current developments in the statistics community suggest that modern statistics education should be structured holistically, that is, by allowing students to work with real data and to answer concrete statistical questions, but also by educating them about alternative frameworks, such as Bayesian inference. In this article, we describe how we...

Realistic interseismic strain rate uncertainties from inherently sparse GNSS-networks

Before geodetically derived strain and rotation rates can be robustly compared to geological or seismological observations, we need reliable strain rate uncertainties. Various methods exist to compute strain rates from GNSS-derived interseismic velocities, but a realistic representation of interpolation uncertainties has remained a challenge....

Estimating geodynamic model parameters from geodetic observations using a particle method

Bayesian-based data assimilation methods integrate observational data into geophysical forward models to obtain the temporal evolution of an improved state vector, including its uncertainties. We explore the potential of a variant, a particle method, to estimate mechanical parameters of the overriding plate during the interseismic period....
