Based on an extension of Fenchel inequality, bipotentials are non smooth mechanics tools, used to model various non associative multivalued constitutive laws of dissipative materials (friction contact, soils, cyclic plasticity of metals, damage). Given the graph M ⊂ X × Y of a multivalued law T : X → 2 Y , we state a simple necessary and sufficient(More)
A recent paper has described a new functional method, the symmetrical centre of rotation (SCoRE), for locating joint centre position [Ehrig, R.M., Taylor, W.R., Duda, G.N., Heller, M.O., 2006. A survey of formal methods for determining the centre of rotation of ball joints. Journal of Biomechanics 39 (15), 2798-2809]. For in vitro analyses, the SCoRE method(More)
This is a survey of recent results about bipotentials representing multival-ued operators. The notion of bipotential is based on an extension of Fenchel's inequality, with several interesting applications related to non associated con-stitutive laws in non smooth mechanics, such as Coulomb frictional contact or non-associated Drücker-Prager model in(More)
We present the high-energy-neutrino follow-up observations of the first gravitational wave transient GW150914 observed by the Advanced LIGO detectors on Sept. 14 th , 2015. We search for coincident neutrino candidates within the data recorded by the IceCube and Antares neutrino detectors. A possible joint detection could be used in targeted electromagnetic(More)
Voltage nonlinearity is studied in microelectronic metal / insulator (oxide) / metal capacitors. The influence of electrodes (work function, oxygen affinity) and test parameters (dc or ac bias, frequency) are investigated. A physical model is proposed to explain the capacitance-voltage relation. The model is based on electronic hopping trough oxygen vacancy(More)
Resistance switching in HfO<sub>2</sub> metal-insulatormetal devices is investigated through current-voltage (I-V) and current-time (I-t) measurements. Depending on electrodes, a high-to-low resistance transition is observed in I-V characteristics at high or low voltages (OXRAM and CBRAM behaviors). This is correlated in the I-t characteristics to a(More)
The cross section of the diffractive process e + p → e + Xp is measured at a centre-of-mass energy of 318 GeV, where the system X contains at least two jets and the leading final state proton p is detected in the H1 Very Forward Proton Spectrometer. The measurement is performed in photoproduction with photon virtualities Q 2 < 2 GeV 2 and in deep-inelastic(More)
