This work presents the design and application of a quantum sensor using a point NV defect in a nanodiamond crystal lattice for in vitro applications. Our aim is to present the design of a quantum sensor using printed circuit boards (PCBs) and to investigate the quantum response ... En savoir plus

Prediction of Noise Generated by Electromagnetic Forces in Induction Motors

M. K. Nguyen[1], R. Haettel[2], A. Daneryd[2]
[1]KTH, Stockholm, Sweden
[2]ABB Corporate Research,Västerås, Sweden

Induction motors, as any other industrial products, have to comply with various requirements on noise levels. Therefore, it is essential to use an appropriate prediction tool to verify and optimize the design of an induction motor with respect to the acoustic performances. The paper ... En savoir plus

Simulation of Medical Treatment for Infections After Knee Replacement Surgery

Josh Thomas¹, Luke Gritter¹, Kyle Koppenhoefer¹, Bibin Prasad², John Tepper², Rajiv Chopra²
¹AltaSim Technologies, Worthington, OH, United States
²Solenic Medical, Addison, TX, United States

While prosthetic joints can improve people’s quality of life, there is an unmet need for the treatment of post-surgery infections. A novel technology has been developed that can treat these infections with electromagnetic heating. A series of anatomical models of knees with implants ... En savoir plus

An analogy between open boundary condition and infinite element domains

Affifa Adeeb¹, Timothy J Flack¹
¹University of Cambridge, Cambridge, United Kingdom

A magnetic field associated with current carrying coil(s) extends towards infinity, but an analytical model is of finite size. In the finite element analysis (FEA) of electromagnetic systems, open space needs to be modelled as close to reality as possible to get reliable results without ... En savoir plus
