Modeling the Sound Radiation by Loudspeaker Cabinets

M. Cobianchi[1], M. Rousseau[1]
[1] B&W Group Ltd, Steyning, UK

While musical instruments often rely on a body which resonates on purposefully to amplify the vibration produced by a string or a membrane, such as in a violin or a guitar, loudspeaker cabinets should not contribute at all to the total sound radiation, but aim instead to be a perfectly ...

Electrostatic Fluid Structure Interaction (EFSI) on the Huygens Experiment

R. Godard [1], J. de Boer[1], N. Ibrahim[2], and G. Molina-Cuberos[3]
[1]Royal Military College of Canada, Kingston, ON, Canada
[2]University of Toronto, Toronto, ON, Canada
[3]Campus Espinardo, Murcia, Spain

The Huygens Atmospheric Structure Instrument (HASI) was designed to characterize the physical properties of the lower atmosphere and surface of Titan, the planet-size moon of Saturn. The Relaxation Probe (RP) sensor on the Huygens probe, determined the electrical conductivity in the ... En savoir plus

Reliable Full-Wave EM Simulation of a Single-Layer SIW Interconnect with Transitions to Microstrip Lines

J. L. Chavez-Hurtado[1], J. E. Rayas-Sanchez[1], Z. Brito-Brito[1]
[1]ITESO - Universidad Jesuita de Guadalajara, Tlaquepaque, Jalisco, Mexico

We present a procedure to obtain reliable EM responses for a SIW interconnect with microstrip line transitions. The procedure focuses on two COMSOL® configuration settings: meshing size and simulation bounding box. Once both are properly configured, the implemented structure is tested by ... En savoir plus

How Finite Element Analysis Revolutionized a 100-Year Old Equation

K. Carlson [1], J. Arle [1], J. L. Shils [2], L. Mei [1],
[1] Beth Israel Deaconess Medical Center/Harvard Medical School, Boston, MA, USA
[2] Rush Medical Center, Chicago, IL, USA

In 1901 Weiss proposed an equation predicting activation of nerve fibers by electrical stimulation, used in neuroscience and neuromodulation, which applies electric fields to modify nerve behavior in neurological disorders. Weiss’ equation is relative to geometry, electrode array, ... En savoir plus

Investigations on Polarization Losses in Planar Solid Oxide Fuel Cells

S. T. Aruna [1], S. Senthil Kumar [1], A. Iyer [1], B. ShriPrakash [1]
[1] CSIR-National Aerospace Laboratories, Bangalore, Karnataka, India

In recent years, various configurations of planar Solid Oxide Fuel Cells (SOFC) have been developed for enhancing its performance. The objective of these efforts are centered on reducing polarization losses (also referred as "overpotential") by optimizing the structure and properties of ... En savoir plus

Loudspeaker Simulations in a Car Cabin

F. Malbos [1], M. Bogdanski [2], M. Strauss [2]
[1] Harman France, Paris, France
[2] Harman Becker Automotive Systems, Straubing, Germany

The goal of this study is to improve the audio simulation accuracy for automotive applications. COMSOL® Acoustics Module and LiveLink™ for MATLAB® were used to simulate the sound pressure generated by a loudspeaker in a car cabin. A comparison between simulated and measured sound ...

Thermo-Mechanical Analysis and Fatigue Life Prediction for an Electronic Surface-Mount Device (SMD)

G. Petrone [1], C. Barbagallo [1], M. Scionti [1],
[1] BE CAE and Test, Catania, Italy

Electronic devices produce a very high rate of specific heat with respect to their dimensions. Exceeding in maximum safe operating temperature means strong reduction of efficiency, reliability and lifetime. In addition, electronic devices are subjected to periodical thermal loading. ...

Contactless Power and Data Transfer for Multiple Nonlinear Loads

H.P. Schmidt [1], U. Vogl[1]
[1]UAS HAW Amberg-Weiden, Amberg, Germany

For the design of an inductive power and data transfer electromagnetic calculation are carried out. A transfer system is considered for loads that are distributed across some distances. For example, such loads are adjustable speed drives that are found in factory automation and intra ... En savoir plus

Analysis of Acoustic Response of Rooms

J.S. Crompton[1], L.T. Gritter[1], S. Yushanov[1], K.C. Koppenhoefer[1], and D. Magyari[2]
[1]AltaSim Technologies, LLC, Columbus, OH, USA
[2]Golden Acoustics, Detroit, MI, USA

The preferred acoustic response of recording studios, auditoriums and conference halls is to have an even energy response over the entire room and throughout full audio spectrum. This can be accomplished by using acoustic panels with complex surface structures that scatter acoustic waves ... En savoir plus
