Modeling Transport of Antimicrobials Encapsulated in Yeast Microparticles for Biofilm Inactivation

J. Yi1, N. Nitin1, K. Huang2
1University of California-Davis, Davis, CA, USA
2University of Auckland, Auckland, New Zealand

A biofilm is a community of microbes embedded in a self-secreted polymer matrix. It may persist in different environments, and in the case of pathogens, these biofilms can be a significant risk factor for foodborne disease and healthcare-associated infections. Due to the unique structure ... En savoir plus

Mathematical and Computational Analysis on Sintering Densification of Binder Jet Printed Valvebody

R. Sun1, H. Liu1, H. Zhang1
1Purdue University, West Lafayette, IN, USA

Binder jet printing (BJP) is one of the additive manufacturing methods that are being widely implemented as an efficient alternative for casting and machining in the automotive industry. Sintering densification of the as-printed part (green part) adds uncertainty and possible undesirable ... En savoir plus

Optimizing Three-Dimensional Microelectrode Geometries for Neurostimulation

L. van de Panne1, K. Haider1, T. Lijnse1, C. Dalton1
1University of Calgary, Calgary, Alberta, Canada

Neuromodulation, a closed-loop therapy that combines the recording and stimulation of neurons using implanted electrodes, is widely considered the future of care for many neurological diseases including epilepsy and Parkinson’s. Existing neuromodulation therapies, however, are limited by ... En savoir plus

COMSOL® Modeling of Self-Limiting Electrospray Deposition

C. Nachtigal1, D. Kovacevich1, L. Lei1, J. Singer1
1Rutgers University, New Brunswick, New Jersey, USA

Electrospray Deposition (ESD) is a process used in manufacturing that utilizes a charged capillary to disperse a flowing liquid into a spray that deposits onto a grounded target substrate. The build-up of charge on the substrate can begin to deflect further spray, allowing the material ... En savoir plus

System Reliability Analysis Using Monte Carlo Based Method and Neural Networks

O. Elshafiey1, Y. Deng1
1Michigan State University, East Lansing, MI, USA

This paper examines and develops a method for calculating the probability of structural failure by using Monte Carlo simulation and combining it with a neural network approach. In order to assess the validity of this method, a simple concrete beam model with a corrosion crack is built ... En savoir plus

3D Inspection of AM Components Using CT: From Defect Detection to Thermal Simulation in COMSOL Multiphysics®

K. Genc1, C. Butler2, B. Nye3, B. L. Toralles3, N. Turner3, N. Brierley3, P. Young4
1Synopsys, Inc., Mountain View, CA, USA
2Synopsys NE Ltd, Exeter, United Kingdom
3Manufacturing Technology Centre, Coventry, United Kingdom
4University of Exeter, Exeter, United Kingdom

Metal Additive Manufacturing (AM) can be used to create topologically complex designs that would otherwise be difficult or impossible to produce using traditional methods. However, non-destructive inspection and testing of these structures is made difficult by the presence of internal or ... En savoir plus

Predictive Analytics and Uncertainty Quantification of a Microscale Porous Reactor Simulation

G. Jones1, R. McConnell1
1SmartUQ, Madison, WI, USA

The use of computer simulations to analyze systems during the design process is a popular approach for validating and optimizing designs. But simulations are deterministic in nature and do not consider the uncertainty in design, manufacturing, and use of the product. Using predictive ... En savoir plus
