TL;DR: In this article, the authors presented a multi-stack FC configuration inside the EV to minimize its start up, heating/cooling, and cycling problems via proposing a novel thermal management approach.
Abstract: Global climate change, energy independence and sustainability have encouraged automotive sector stakeholders to adopt further technological researches on the integration of Fuel Cell (FC) within Electric Vehicles (EVs). This paper aims at presenting a multi-stack FC configuration inside the EV to minimize its start up, heating/cooling, and cycling problems via proposing a novel thermal management approach. Simulation results, using MTCSim© software, illustrates that proper thermal management of the EV's multi-stack FC significantly enhances its life span, cycling, and efficiency, besides optimizing its operation performance.

TL;DR: In this paper, the authors used an inflation-extension test to identify the parameters of a hyper-viscoelastic model suitable for describing the mechanical behavior of vascular tissues, focusing on the aorta.
Abstract: The aim of the present study was to develop and validate a method based on medical imaging to identify the parameters of a hyper-viscoelastic model suitable for describing the mechanical behavior of vascular tissues, focusing on the aorta. The method uses an inflation-extension test, and the model comprises one hyperelastic element in parallel with one or more Maxwell elements. Cylindrical samples of elastomeric silicone materials with a mechanical behavior similar to vascular tissues were placed in a circuit simulating hemodynamic flow through adequate controlled-pressure variation. Ultrasound B-mode image sequences were analyzed to measure the cyclic circumferential and longitudinal elongations. Precautions were taken a posteriori to resynchronize pressure and deformation signals, and thus minimize errors in the viscosity parameters estimated. The hyper-viscoelastic parameters of the samples were identified with reasonable accuracy as compared with the values obtained via standard measurements, namely tensile tests and dynamic mechanical analysis. However, the estimates of the viscosity parameters can be hampered in the case of stiffer samples. This limitation is bound to a restricted range of frequencies analyzed by the test, which mainly depends on the image acquisition rate. The use of the present method in the clinical environment for in vivo experiments can be foreseen provided that the local pressure measurements are available.
