The interaction between flow-induced vibration mechanisms of a square cylinder with varying angles of attack [PDF]

, 2012
This study examines the influence of angle of attack of a square section cylinder on the cylinder’s flow-induced vibration, where the direction of the vibration is transverse to the oncoming flow.

The refined inviscid stability condition and cellular instability of viscous shock waves [PDF]

, 2009
Combining work of Serre and Zumbrun, Benzoni-Gavage, Serre, and Zumbrun, and Texier and Zumbrun, we propose as a mechanism for the onset of cellular instability of viscous shock and detonation waves in a finite-cross-section duct the violation of the ...

Meta‐Virtuality: Strategies of Disembeddedness in Virtual Interiorities

Journal of Interior Design, EarlyView., 2022
ABSTRACT To reclaim their seat in the rapidly growing market of virtual space, designers of the built environment can benefit from reevaluating theories that see the virtual as a mere extension/reflection of the physical. By claiming ontological autonomy from external worlds, the virtual is liberated from the hegemonic control of the physical.
