³Dr. Sennewald Medizintechnik GmbH, Munich, Germany

Heat cancer therapy (HT) involves increasing tumor temperatures to 40-44°C and is a potent radiosensitizer for the treatment of solid tumors, including brain cancer. Current strategies to heat deep-seated targets in the brain are primarily invasive, and existing HT applicators do not ... Read More

Electron Drift in Xe Gas

T. J. Berger [1],
[1] Department of Physics, Applied Physics, and Astronomy, Rensselaer Polytechnic Institute, Troy, NY, USA

The XENON Dark Matter Experiment utilizes ultra-pure xenon (Xe) as a target for particle interaction in the effort to detect dark matter particles. To measure the purity of Xe, a gas purity monitor (GPM) is being developed which drifts electrons through Xe gas to detect impurities that ... Read More

Finite Element Simulation of Shear Wave Propagation Induced by a VCTE Probe

S. Audière[1,2], M. Charbit[1], E. Angelini[2], V. Miette[2], J. Oudry[2], and L. Sandrin[2]
[1]Institut Telecom, Telecom ParisTech, Paris, France
[2]Echosens, Paris, France

The Fibroscan® (Echosens, Paris, France) device based on vibration–controlled transient elastography (VCTE) is used to non– invasively assess liver stiffness correlated to the hepatic fibrosis. Stiffness is quantified by measuring the velocity of a low–frequency shear wave traveling ... Read More

On The Directional Response of Multi-Driver Column Loudspeaker Configurations Using FEA and BEM

R. Balistreri [1],
[1] Klipsch Group, Inc, Indianapolis, IN, USA

Column Loudspeakers employ multiple drivers to get close to a radiating line source. A line source gives several acoustic advantages versus a point source, especially in highly reverberant environments. This property particularly has made column loudspeakers the preferred solution in ... Read More

Two-Phase Flow Modeling of Metal Vaporisation under Static Laser Shot Using a Double ALE Method

Y. A. Mayi [1], M. Dal [1], P. Peyre [1], M. Bellet [2], C. Metton [3], C. Moriconi [3], R. Fabbro [1],

[2] CEMEF Laboratory, UMR 7635 PSL Research University MINES ParisTech, Sophia Antipolis, France
[3] Safran, Paris Cedex, France

Additive manufacturing gathers technologies where near net shape components are produced by depositing successive layers of materials. Among these technologies, the Layer Beam Melting (LBM) process – often referred to as Selective Laser Melting (SLM) – is garnering industrial interest, ... Read More

Benchmark Model: Natural Convection of Water-Aluminum Oxide Nanofluids in a Square Cavity

M. Z. Saghir [1], A. Ahadi [1], A. A. Mohamad [2],
[1] Department of Mechanical Engineering, Ryerson University, Toronto, ON, Canada
[2] Department of Mechanical Engineering, University of Calgary, Calgary, AB, Canada

Nanofluids is a new class of fluid consisting of particles in a liquid. Different base liquid has been proposed and the most common one is water. The concentration of these particles can range from 0.1% to 5% or greater. Different numerical models have been proposed to solve this ... Read More

A Study on Hydrodynamics of Melt Expulsion in Pulsed Nd: YAG Laser Drilling of Titanium

[1] Indian Institute of Technology Kanpur, Kanpur, India
[2] Indian Institute of Information Technology, Design and Manufacturing, Jabalpur, India
[3] Integral University, Lucknow, India

Laser drilling of titanium and its alloys is widely used in aerospace industry, as it offers selective removal of material at high accuracy and speed. However, laser drilling often inherits defects such as large heat affected zone, micro cracks and recast layer. These defects depend upon ... Read More
