Two-photon excitation laser induced fluorescence (2p-LIF) is used here for imaging an optically dense atomizing spray. The main advantage of the approach is that very little fluorescence interference originating from multiple light scattering is generated. This leads to high image contrast and a faithful description of the imaged fluid structures. While point measurement 2p-LIF imaging is a well-k
In this paper we present numerical simulations of soil plasticity using isogeometric analysis comparing the results to the solutions from conventional finite element method. Isogeometric analysis is a numerical method that uses nonuniform rational B-splines (NURBS) as basis functions instead of the Lagrangian polynomials often used in the finite element method. These functions have a higher-order
The results from a new numerical method for simulating the strength and fracture locations of small glass specimens subjected to double ring bending are compared with experimental data. The method implements the weakest-link principle while assuming the existence of Griffith flaws. A Weibull distribution for the strength is simulated based on a single population of Pareto distributed crack sizes.
Experimental data on the strength of new annealed float glass tested in an ambient environment was collected. A comparison was made between four standard distributions, the normal, lognormal, Gumbel and Weibull, with respect to the performance in modelling the strength. The Weibull distribution outperformed the normal and lognormal distributions when the data contained edge only failure origins. W
The applicability of the Weibull distribution to model the strength of glass, the existence of a size effect on the strength and the need for a non-destructive testing of the strength are discussed and reviewed. There are a growing number of studies that put into question the applicability of the Weibull distribution to model annealed glass fracture data. A recent study indicates that the breakage
A numerical method is applied to model the fracture stress and failure location in glass panes subjected to various bending arrangements. The method assumes the weakest-link principle and the existence of surface microcracks. The fracture stress and failure origin are revealed through a search algorithm. The magnitude of strength and the location of fracture are stochastic in nature and can be pre
A detailed overview is provided for the strength of monolithic annealed float glass panes according to experiments carried out over the past four decades. The experiments were conducted with the coaxial double ring bending device, the three-point bending device, the four-point bending device, and the arrangement that allows for laterally supported plates to be subjected to uniform pressure. When t
This mapping provides an overview of different types of arenas where the two concepts Ecosystem-based adaptation (EbA) and Blue Carbon (BC) are discussed. EbA has been defined by the Convention on Biological Diversity (CBD) as “The use of biodiversity and ecosystem services as part of an overall adaptation strategy to help people to adapt to the adverse effects of climate change.” (CBD, 2009). BC
This report is a result of a cooperation project between Lund University in Sweden and the Koninklijk Nederlands Meteorologisch Instituut, KNMI, in the Netherlands. The overall aim of the project was to provide an initial mapping of providers and purveyors of climate services in the Netherlands and Sweden. In total, 64 organisations participated in the study, through questionnaire replies and/or i
