Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... En Savoir Plus
Approximately 450,000 people worldwide suffering from hearing problems use cochlear implants (http://www.cochlear.com/au/home/connect/cochlear-hearing-ambassador, June 12, 2018). Manual insertion of the cochlear implant during surgery can potentially damage the delicate tissues within ... En Savoir Plus
High intraocular pressure (IOP) is a risk factor for glaucoma, a condition that can cause blindness. Conventional ways of measuring IOP either require contact or can be uncomfortable for the patient. We have developed a method to measure IOP from the propagation time of a wave on the ... En Savoir Plus
Time-Resolved Optical Tomography in Preclinical Studies: Propagation of Excitation and Fluorescence Photons.
We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using ... En Savoir Plus
Excilamps are artificial Ultraviolet sources based on the emission of excimers or exciplexes. The latter are excited states of weakly bound rare gas or halide/rare gas atoms which emit a photon in the UV region when they dissociate. Dielectric Barrier Discharge (DBD) excilamps are ...

The presence of a moving fluid in a porous rock modifies its mechanical response. Poroelasticity explains how the fluid inside the pores bears a portion of the total load supported by the rock. The remaining part of the load is supported by the elastic skeleton, which contains a laminar ... En Savoir Plus
The inverse diffusion problems deal with the estimation of many crucial parameters such as the diffusion coefficient, source properties, and boundary conditions. Such algorithms are widely applied in many design problems in different physical, chemical, and biological fields. Recently, ... En Savoir Plus
Fundamental Three Dimensional Modeling and Parameter Estimation of a Diesel Oxidation Catalyst for Heavy Duty Trucks
Mathematical optimization can be used as a computational engine to generate the best solution for a given problem in a systematic and efficient way. In the context of monolithic converter systems, the parameter estimation problem (or inverse problem) is solved using Partial Differential ... En Savoir Plus
This paper presents and discusses HazRes’ research and results associated with the simulation and modelling of hydrogen release and dispersion events in indoor enclosed environments, using COMSOL Multiphysics. HazRes has developed a gas dispersion model in COMSOL, which takes into ... En Savoir Plus
In the inspection of steel products with respect to flaws a magnetic flux leakage (MFL) test procedure can be applied. In this procedure a “horseshoe” shaped yoke is used, whose legs are wrapped with coils through which an alternate current with a high frequency (3 kHz) is flowing. ... En Savoir Plus
