Nonlinear Speed Control of Switched Reluctance Motor Drives Taking into Account Mutual Inductance by M. Alrifai, M. Zribi, R. Krishnan, M. Rayan

“…The control scheme adopts two-phase excitation; exciting two adjacent phases can overcome the problems associated with single-phase excitation such as large torque ripple, increased acoustic noise, and rotor shaft fatigues. The effects of mutual coupling between two adjacent phases and their contribution to the generated electromagnetic torque are considered in the design of the proposed control scheme for the motor. …”

A Scenario for Origin of Global 4 mHz Oscillations in Solar Corona by Li Xue, Chengliang Jiao, Lixin Zhang

“…This result is consistent with global observations of Alfvénic waves in corona and can naturally explain the observational ubiquity of <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>4</mn><mspace width="2pt"></mspace><mi>mHz</mi></mrow></semantics></math></inline-formula> without the difficulty of the <i>p</i>-mode passing through the acoustic-damping chromosphere.

Les Songes de la nef, pour une « prise de site » musicale et sonore by Alain Bonardi

“…We show that the installation is to be considered as a framework setting a certain number of relationships with the place, acoustic ones first of all. It also enables wandering visitors to discover relationships between the sound content and the Hôtel-Dieu, and therefore get a new understanding of this monument.…”

Qualité de l’air et nuisances sonores dans les vallées alpines de transit by Jürg Thudium

“…With regard to noise, the valleys are affected equally bad: The “amphitheatre effect” carries the noise to the higher reaches that would not be exposed to so much acoustic irradiation if the source of noise was situated at the same distance in the open country; furthermore, protection from the noise reflected by the slope is difficult. …”
