[2] Department of Computational Optimization, University of Szeged, Szeged, Hungary

Core-shell type plasmonic nanoresonators have been optimized to maximize the fluorescence rate of coupled dipolar emitters, namely SiV color centers in diamond. The RF module of the COMSOL Multiphysics® software was applied to extract the optical response and to analyze the near-field ... En savoir plus

Numerical Modeling and Verification of Acoustic Streaming Induced by Ultrasonic Treatment

D. Rubinetti [1], D. A. Weiss [1], J. Müller [2], A. Wahlen [2],
[1] Institute of Thermal and Fluid Engineering, University of Applied Sciences Northwestern Switzerland, Windisch, Switzerland
[2] Institute of Product and Production Engineering, University of Applied Sciences Northwestern Switzerland, Windisch, Switzerland

Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... En savoir plus

Evaluation of Binary Mixture Models for 3D Printed Biosensors

J. Persad [1], S. Rocke [1], D. Ringis [1], A. Abdool [1],
[1] Department of Electrical and Computer Engineering, University of the West Indies, St. Augustine, Trinidad and Tobago

3D printing as applied to the area of electronics manufacture covers a broad range of traditional printing technologies [1]. The attraction in 3D printing lies in its potential to disrupt the traditional photolithographic/subtractive manufacturing line with simpler additive processes. ... En savoir plus

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J.-D. Wheeler [1], ,
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... En savoir plus

Magnetic Ratchet

A. Auge, F. Wittbracht, A. Weddemann, and A. Hütten
Department of Physics, University of Bielefeld, Germany

Transport phenomena in spatially periodic magnetic systems, in particular the directed transport of magnetic beads in a so called magnetic ratchet (Brownian motor) are considered. Simulations are carried out to test and optimize this system, where the Smoluchowski equation with flux ... En savoir plus

Sruthi Dinesh [1], Dr.C.K.Aanandan [1],
[1] Cochin University of Science and Technology, Kochi, Kerala, India

A) Abstract: There has been a spectacular growth in the field of wireless communication in recent years. Current trends in mobile wireless communications demand technologies that allow a single device or system to operate across multiple frequency bands and protocols. This cannot be ... En savoir plus

Simulating Light Propagation during I-PDT of Locally Advanced Head and Neck Cancer

E. Oakley [1], H. Arshad [1], G. Shafirstein [1],
[1] Roswell Park Cancer Institute, Buffalo, NY, USA

Interstitial photodynamic therapy (I-PDT) can be applied for the treatment of locally advanced head and neck squamous cell carcinoma (LA-HNSCC). The complex anatomy of LA-HNSCC requires careful planning of the light delivery and fiber insertion. We have developed an image-based approach, ... En savoir plus
