A recently modified Elasto-Plastic Self-Consistent (EPSC) model which empirically accounts for both intergranular and intragranular back stresses has been successfully used to simulate the cyclic (tension-compression) loading behaviour of an Fe-24Mn-3Al-2Si-1Ni-0.06C TWinning Induced Plasticity (TWIP) steel between strain limits of ±1%. Lattice strain measurements acquired via in-situ neutron diffraction were used to further validate the modelling results. An improved prediction of the pronounced Bauschinger effect during unloading is achieved when the reversibility of partial slip in the 〈112〉 direction is accounted for. This result indicates a potential contribution of the stress-induced separation of partial dislocations to the observed early yielding …

Quels sont les déterminants de la mobilité résidentielle en Belgique ? Quand on déménage, quels sont les facteurs de choix d'une nouvelle commune de résidence ? Telles étaient les questions au cœur du projet MOBLOC. Dans ce cadre, un modèle a été développé en deux parties: un modèle de propension à migrer et un modèle de choix de nouvelle localisation. L'objectif étant de travailler avec un niveau de désagrégation spatiale fin (les 589 communes belges), des outils de micro-simulation étaient également nécessaires. La méthode originale développée par le GRT pour créer des populations synthétiques est donc utile de même que …

Wavelet Transform Based De-Noising Method For Self Mixing Interferometry Signals, Yuan Sun, Yanguang Yu, Jiangtao Xi

Self-mixing interferometry (SMI) signals are observed from a laser diode (LD) with optical feedbacks induced by an external target. SMI signals carry information related to both of the target and parameters of the LDs. However, the noise contained in SMI signals greatly degrades the applications of the SMI systems. This paper proposes a wavelet transform based de-noising method which can effectively eliminate noise while keeping an SMI waveform less changed. The proposed method is verified by both simulations and experiments

Un resultado bien conocido en la teor´ıa elemental de n´umeros, usualmente atribuido a Euclides, dice que hay un n´umero infinito de primos. Existen varias demostraciones de este resultado [1, 3] pero en esta nota mostraremos en detalle el enfoque ingenioso de Furstenberg [2], que utiliza conocimientos b´asicos de topolog´ıa, por ejemplo, espacios topol´ogicos, conjuntos abiertos y conjuntos cerrados.

Laboratory-scale testing investigated the degree of Cryptosporidium oocyst reduction provided by diatomaceous earth (DE) filtration. Three grades of DE from two manufacturers were used in the tests. Reduction was measured using seeded river water applied to Walton test filters. Tests were run for filtration rates of 1 and 2 gpm/sq ft (2.4 and 4.9 m/h). Each run was replicated three times, and quality control was rigorous. Approximately 6 logs of reduction in the concentration of Cryptosporidium oocysts can be expected under routine operating conditions using DE grades having permeability of <1.2 Darcy. Log reductions varied predictably according to the permeability of the DE grade and the filtration rate; they were significantly higher at the higher filtration rate. Agreement was excellent between runs, enabling researchers to distinguish with consistent statistical significance the differences in performance.
