Using Multiphysics for Detecting Atmospheric Ice Through MuVi Graphene - Atmospheric Icing Sensor

U. N. Mughal [1],
[1] Narvik University College, Norway

This paper is a preliminary design study to develop a hybrid atmospheric icing sensor which have an adequate potential to detect an icing event, icing type and icing rate together with icing load. The physics to detect icing event and icing type have been numerically understood using ... 詳細を見る

Analysis of Stress-induced Pockels Effect in Silicon Waveguides

C. L. Manganelli [1], P. Pintus [1], C. Bonati [2], F. Di Pasquale [1]
[1] Scuola Superiore Sant'Anna, Pisa, Italy
[2] INFN - Sezione di Pisa, Pisa, Italy

The recently discovered Pockels effect in strained silicon has made silicon a promising candidate material for optical modulators and switches. In this work, we propose a model that links the electro-optic effect to the applied strain (in fact to the strain gradient). This model may be ... 詳細を見る

Modeling the Electrical Parameters of a Loudspeaker Motor System with the AC/DC Module

M. Cobianchi [1], M. Rousseau [1], S. Xavier [1],
[1] B&W Group Ltd., Worthing, West Sussex, United Kingdom

The main purpose of a drive unit is to transform the electrical signal at its terminals into acoustic waves via two transduction mechanisms: electro-mechanical and mechano-acoustical. In this paper only the electro-mechanical transformation is discussed in view of a future optimization ... 詳細を見る
