Impact of the Forces due to CLIQ Discharges on the New HL-LHC Beam Screen

M. Morrone [1], C. Garion [1],
[1] CERN, Geneva, Switzerland

In the framework of the high luminosity large hadron collider (HL-LHC) project, important upgrades will take place by 2024 including the installation of new superconducting magnets in which new beam screens will be placed. The beam screen is an octagonally shaped pipe inserted into the ... En savoir plus

Microfluidic Separation System for Magnetic Beads

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

It is possible to control the motion of magnetic beads using a combination of hydrodynamic and electromagnetic forces. In this work, we investigate the possibility to manipulate the motion of beads with different magnetic moments in a special microfluidic structure so as to separate ... En savoir plus

Investigation of Silicon Etching Process with COMSOL®

D. Kray [1], L. Leis [1],
[1] University of Applied Sciences Offenburg, Germany

In this work we investigate a wet-chemical silicon etching process. COMSOL Multiphysics® is used to extract local pressure values to correlate them to experimental results. The test setup consists of a box with a fixed wafer and a nozzle that injects an etchant jet onto the wafer ... En savoir plus

Calculating Iron Losses Taking into Account Effects of Manufacturing Processes

P. Goes, E. Hoferlin, and M. De Wulf
OCAS N.V. – ArcelorMittal Research Gent, Belgium

Finite element modelling of electrical machines usually assumes uniform magnetic properties and loss behaviour throughout the steel laminations. It is well known that manufacturing processes, like the assembly of the machine, deteriorate the properties of the core material. Generally, ... En savoir plus

An App for Additive Manufacturing Design Assessment

B. Lazaro Toralles [1], S. Afazov [1], A. Yaghi [1], W. A. D. Denmark [1], A.N. Holloway [1],
[1] The Manufacturing Technology Centre Ltd., Coventry, United Kingdom

The Manufacturing Technology Centre (MTC) is home to the UK’s National Centre for Net Shape and Additive Manufacturing, offering integrated solutions to potential end users, supply chain companies or equipment providers using a three phase approach: discovery, demonstration and pilot ...

[1]Lynntech, Inc., College Station, Texas, USA
[2]Micro Nano Devices and Systems (MiNDS) Laboratory, Department of Electrical Engineering, University of Texas at Dallas, Texas, USA

A portable device that can identify protein and peptides real time in complex biological systems such as human bodily fluids reliably and accurately is in high demand to properly diagnose and treat medical conditions. Lynntech has developed an innovative Polydimethylsiloxane (PDMS) based ... En savoir plus

Decomposition of Fundamental Lamb Wave Modes in Complex Metal Structures Using COMSOL Multiphysics®

M. Harb [1], R. Malaeb [1], E. Mahfoud [1],
[1] Department of Mechanical Engineering, American University of Beirut, Libanon

Structural Health Monitoring Systems are being highly investigated to evaluate the health of a structure and detect any damages occurring in real time. Such systems require intensive data analysis which gets even more intricate when working with complex structures due to undesirable ... En savoir plus

Numerical Evaluation of the Polarizability Tensors of Stem Cells with Realistic 3D Shapes

S. Baidya [1], A. M. Hassan [1], B. A. Pazmiño Betancourt [2], J. F. Douglas [2], E. J. Garboczi [3],
[1] Computer Science Electrical Engineering Department, University of Missouri - Kansas City, Kansas City, MO, USA
[2] Materials Science and Engineering Division, National Institute of Standards and Technology, Gaithersburg, MD, USA
[3] Applied Chemicals and Materials Division, National Institute of Standards and Technology, Gaithersburg, MD, USA

Most of the reported studies on the electrical characteristics of biological cells assume that they have simple shapes like spheres or ellipsoids due to the lack of information about their accurate 3D shape. However, the actual shape of a cell can be quite fractal and it must be taken ... En savoir plus

Plasmon Enhanced Fluorescence Characteristics Government by Selecting the Right Objective Function

M. Csete [1], A. Szenes [1], D. Vass [1], B. Bánhelyi [2], T. Csendes [2], G. Szabó [1]
