A study on the sub-regionalization of humanitarian supply chain: the IFRC case
2016
- Humanitarian Supply Chain (HSC) performance is a key factor for disaster response. In order to be more responsive, the typical humanitarian supply strategy has evolved from a centralized to a decentralized network, generally at regional level. The objective was to reduce lead-times and costs. However, after a decade of working, organizations like the Americas and Caribbean International Federation of the Red Cross and Red Crescent (IFRC) have noticed that those objectives are only partially reached and have decided to go further in the evolution by developing sub-regionalized networks. In this study, we analyse the HSC sub-regionalization process to better understand the challenges and op…

Advanced dispersion measurement techniques for the characterization of the mechanical properties of poro-visco-elastic materials
2013
Dispersion measurement techniques are normally used to determine the mechanical properties of poro-visco-elastic materials, such as their shear modulus. However, dispersion measurements of poro-visco-elastic materials are not easy and the experimentally accessible frequency range in which the modes of propagation are detectable is limited to the lower frequency range, typically up to about 1500 Hz. In this article an advanced measurement technique is discussed to perform the dispersion measurement, allowing to capture reliable measurement data up to higher frequencies and for higher order modes of propagation. A typical measurement result using the proposed approach is shown and the results…
