Ascent and movement of buoyant fluids in the lithosphere
Brice Tanguy Alphonse Lecampion, Andreas Möri, Carlo Peruzzo
Hydraulic fractures are driven by an internal fluid pressure exceeding the minimum compressive stress, propagating in a direction perpendicular to the latter. This class of tensile fractures has gained interest over the last fifty years due to the developm ...
2023Vertical and Leg Stiffness Modeling During Running: Effect of Speed and Incline
Kamiar Aminian, Frédéric Meyer, Grégoire Millet, Mathieu Pascal Falbriard
A spring mass model is often used to describe human running, allowing to understand the concept of elastic energy storage and restitution. The stiffness of the spring is a key parameter and different methods have been developed to estimate both the vertica ...
GEORG THIEME VERLAG KG2023Twist-Induced Snapping in a Bent Elastic Rod and Ribbon
Snapping of a slender structure is utilized in a wide range of natural and manmade systems, mostly to achieve rapid movement without relying on musclelike elements. Although several mechanisms for elastic energy storage and rapid release have been studied ...
2019Ultrasonic driving method
A method for driving a first component (11) into a second component (12) by superimposing a mechanical wave of ultrasonic frequency (18) onto the movement (17) of at least one of the components (11, 12). The method comprises a step of adjusting the paramet ...
2016Center-stable manifold of the ground state in the energy space for the critical wave equation
We construct a center-stable manifold of the ground state solitons in the energy space for the critical wave equation without imposing any symmetry, as the dynamical threshold between scattering and blow-up, and also as a collection of solutions which stay ...
Springer Verlag2015Vibrationally Bond-Selective Chemisorption of Methane Isotopologues on Pt(111) Studied by Reflection Absorption Infrared Spectroscopy
In this thesis, I describe the design and first applications of a new molecular-beam/surface-science ultra-high vacuum apparatus. The new machine combines rovibrational state-selective infrared pumping of gas-phase reactants with reflection absorption infr ...
EPFL2012Quantum state-resolved studies of direct and precursor-mediated dissociative chemisorption of silane on Si(100)
In this work, I present the results of my studies on the state-resolved reactivity of silane (SiH4) on the Si(100)-(2x1) surface. The results demonstrate a co-existence of both a direct and a precursor mediated mechanisms for the dissociative chemisorption ...
EPFL2007Surface reactivity of highly vibrationally excited molecules prepared by pulsed laser excitation: CH4 (2 nu(3)) on Ni(100)
Thomas Rizzo, Rainer Beck, Plinio Maroni, Mathieu Schmid
We report state resolved sticking coefficients for highly vibrationally excited CH4 on Ni(100) at well-defined kinetic energies in the range of 12-72 kJ/mol. Incident methane molecules are prepared by pulsed laser radiation in single rovibrational levels o ...
2002Secondary time scales of intramolecular vibrational energy redistribution in CF3H studied by vibrational overtone spectroscopy
Rotationally resolved vibrational overtone spectra of several CH stretch bands of CF3H have been obtained using a combination of jet-cooling, infrared-optical double-resonance, and infrared laser assisted photofragment spectroscopy detection. The high sele ...
