Non-linear oscillatory rheological properties of a generic continuum foam model: comparison with experiments and shear-banding predictions [PDF]

open access: yes, 2012
The occurence of shear bands in a complex fluid is generally understood as resulting from a structural evolution of the material under shear, which leads (from a theoretical perspective) to a non-monotonic stationnary flow curve related to the ...

Experimental study on hypergolic ignition and non-ignition for dicyanamide-based ionic liquids at low impact velocity conditions

open access: yesEnergetic Materials Frontiers, 2021
Ionic liquids have a wide engineering application foresight due to their easy and safe storage and handling while are limited by the unclear mechanism of hypergolic ignition.

Impact of experimental conditions on material response during forming of steel in semi-solid state [PDF]

open access: yes, 2010
Semi-solid forming is an effective near-net-shape forming process to produce components with complex geometry and in fewer forming steps. It benefits from the complex thixotropic behaviour of semi-solids.

Angle of repose revisited: When is a heap a cone?

open access: yesEPJ Web of Conferences, 2017
The angle of repose is a frequently reported value in bulk solids characterisation and its popularity is based on the simple measurement setup. It can be useful to estimate the flowability of a bulk material or to estimate the inner friction coeffcient ...

Foreign countries, foreign customs: an analysis of short-distance mobility of new immigrants in the Rhine-Main region in Germany

open access: yesEuropean Transport Research Review, 2019
Mobility is an important driver of social integration. Against this background, the years since 2014 challenged cities and municipalities in Europe when a large number of immigrating refugees came to Europe and had to be integrated into society. Federal,

Application of Leather Waste Fractions and Their Biochars as Organic Fertilisers for Ryegrass Growth: Agri-Environmental Aspects and Plants Response Modelling

open access: yesEnergies, 2023
The automotive upholstery industry, which processes bovine leathers, has struggled with vast amounts of solid waste, of which the majority are fractions, such as shavings and splits and offcuts, both containing chromium (Cr) and free of Cr. In this work,

Efficient Messaging through Cluster Coordinators in Decentralized Controlled Material Flow Systems

open access: yesMATEC Web of Conferences, 2016
The modularization of the hard- and software is one approach handling the demand for increasing flexibility and changeability of automated material flow systems. A control that is distributed across several different hardware controllers leads to a great

Order Picking and E-Commerce: Introducing Non-Parametric Efficiency Measurement for Sustainable Retail Logistics

open access: yesJournal of Theoretical and Applied Electronic Commerce Research, 2021
Order picking is a crucial but labor- and cost-intensive activity in the retail logistics and e-commerce domain. Comprehensive changes are implemented in this field due to new technologies like AI and automation.

Material implication of Chile’s economic growth: combining material flow accounting (MFA) and structural decomposition analysis [PDF]

open access: yes, 2007
Over the last three decades, the economic integration of the Chilean economy into global markets has been taking place at a rapid pace. For example, in 1986, exports represented 29% of GDP while in 1996 they had increased to 38% of GDP.
