Stochastic fatigue failure prediction of adhesive bonded joints
(2017-05)
This work describes the implementation of the Extended Finite Element Method (a partition of unity finite element method) for the study of fatigue failure of adhesive bonded joints when subjected to variable loading. The ...
Experimental and numerical model to determine the feasibility of using acoustic pulses to detect catheter occlusions
(2011)
The purpose of this research is to determine the capability of detecting central venous catheters occlusions by using guided acoustic waves in a fluid filled tube. The pulse sent through the fluid will be reflected if the ...
Optimization and characterization of a magnetocaloric pump using ferrofluids
(2009-05)
This work presents a detailed analysis of a magnetocaloric pump for electronic cooling applications that runs with no moving mechanical parts and that uses ferrofluid (magnetic fluid) as the working fluid. Mn0.5Zn0.5 Fe2O4 ...
Numerical simulations of on acoustic wave-guided inside a catheter
(2011-12)
People with chronic diseases like cancer or renal failure have permanent catheters trough which drug are administrated or dialysis performed. These catheters can accumulate sediments and be obstructed. Replacing is a viable ...
