In this work, the potential for usage recycled polystyrene and wood flour wastes as materials for development wood plastic composites was evaluated. The effects of wood flour loading and coupling agent addition on the mechanical, dynamic mechanical and morphological properties of polystyrene wood flour composites were examined. The results showed that the mechanical properties decreased with th...
We present an improved quantum mechanical (QM) and molecular mechanical (MM) coupling method for the study of metallic systems. The improved method is based on the earlier work of Choly et al (2005 Phys. Rev. B 71 094101). In this approach, quantum mechanical treatment is spatially confined to a small region, surrounded by a larger molecular mechanical region. This approach is particularly usef...
By coupling a macroscopic mechanical oscillator to two microwave cavities, we simultaneously prepare and monitor a nonclassical steady state of mechanical motion. In each cavity, correlated radiation pressure forces induced by two coherent drives engineer the coupling between the quadratures of light and motion. We, first, demonstrate the ability to perform a continuous quantum nondemolition me...
In this thesis I present experiments investigating controlled coupling between mechanical oscillators and ultracold atoms. I report on three different coupling mechanisms. In a first experiment, the surface potential experienced by atoms close to the mechanical oscillator is employed to couple the oscillator motion to the center of mass (COM) motion of a trapped Bose-Einstein condensate (BEC). ...
eft atrial (LA) size and function have been popularized as barometers of left ventricular (LV) filling pressure and diastolic function. However, the specific role of the left atrium, independent of the left ventricle, and its clinical assessment remain challenging. Several recent investigations have suggested that measuring changes in LA volume (1), wall deformation (2), or the extent of wall f...
An optically thin resonator suspended over a substrate and illuminated with a laser forms an interference field that couples deflection of the resonator to absorption within it. For high enough laser powers, such resonators have been shown to be interferometrically transduced to stable oscillations due to the feedback between heating and deflection. The coupling between thermal stresses, deflec...
2014 It has been observed that in cholesterics shear flow induces a transverse drift of small particles suspended in the liquid crystal. Quantitative measurements of the drift velocity are presented. The effect is interpreted using the analogy of the thermomechanical coupling, predicted for cholesterics. J.

Unilateral airway occlusion permits measurement of single lung function. Since the results suggest that the occluded lung influences the mobility of the contralateral hemithorax, we wanted to test this hypothesis. In eight healthy subjects, we measured, using computed tomography, lung parenchymal area and inner rib cage parasagittal and transverse diameters at three different levels and at maxi...
A complete thermo-hydro-mechanical model is presented to tackle the complex coupling problems encountered in clay barriers. A detailed formulation coupling the heat, moisture (liquid water and water vapour) and, air transfer in a deformable unsaturated soil is given. The formulation of the AlonsoGens’s mechanical model for unsaturated soil is also incorporated. The sensitivity to some parameter...
Positive coupling effect in gas condensate reservoirs is assessed through a pure theoretical approach. A combination of linear stability analysis and long bubble approximation is applied to describe gas condensate coupled flow and relative permeability, thereof. The role of capillary number in gas condensate flow is clearly expressed through closed formula for relative permeability. While the m...
