Surfaces of general type with positive second Segre number s2 := c 2 1 − c2 > 0 are known by the results of Bogomolov to be algebraically quasi-hyperbolic, that is, with finitely many rational and elliptic curves. These results were extended by McQuillan in his proof of the Green–Griffiths conjecture for entire curves on such surfaces. In this work, we study hyperbolic properties of minimal sur...

DOI: 10.1002/admi.201400547 the interaction (characterized by the range of adhesion z 0 ). The intrinsic work of adhesion W adh is the energy per unit area required to separate two planar surfaces from equilibrium contact to infi nite separation. In terms of surface energy (γ i of surface i ) and interfacial energy (γ ij between surfaces i and j ), the work of adhesion is calculated as follows:

This is the second part of an investigation into the visual clues in illuminated scenes, in terms of the interactions between apparent contours, shade and cast shadow curves, boundary edges and markings, on smooth surfaces, pairs of surfaces meeting in a crease, and triples of surfaces meeting in a corner. We consider both ‘stable’ and ‘codimension 1’ cases, the latter meaning that we list even...

Surfaces of general type with positive second Segre number s2 := c1 − c2 > 0 are known by results of Bogomolov to be algebraically quasihyperbolic i.e. with finitely many rational and elliptic curves. These results were extended by McQuillan in his proof of the Green-Griffiths conjecture for entire curves on such surfaces. In this work, we study hyperbolic properties of minimal surfaces of gene...

The surfaces of quasicrystals have been extensively studied since about 1990. In this paper we review work on the structure and morphology of clean surfaces, and their electronic and phonon structure. We also describe progress in adsorption and epitaxy studies. The paper is illustrated throughout with examples from the literature. We offer some reflections on the wider impact of this body of wo...

Our work is centered on the use of implicit surfaces in interactive applications (at least 10 frames per sec) running on high-end consumer architecture (modeling, simulation, deformable body animation, games). We focus on the Marching Cubes algorithm that we tried to implement in an optimized way. We restrict our work to blended iso-surfaces generated by skeletons, since this kind of implicit s...

Over the past decade, the civil engineering community has ever more realized the importance and perspective of reliability-based design optimization (RBDO). Since then several advanced stochastic simulation algorithms for computing small failure probabilities encountered in reliability analysis of engineering systems have been developed: Subset Simulation (Au and Beck (2001) [2]), Line Sampling...

Localized muscle fatigue and perception of fatigue/discomfort in the lower legs induced by a 5 hour standing work task were evaluated for 3 different work surfaces (linoleum tiles on concrete floor, rubber mat, sole insert) in young adults and older individuals. Muscle fatigue was quantified by the muscle twitch force (MTF) magnitude and subjective ratings. The results indicate that the work ta...

Sulcal medial surfaces are 3D thin convoluted ribbons embedded in cortical sulci, and they provide distinctive anatomical features of the brain. Here we propose a new approach to automatic intrasulcal ribbon finding, following our work on cortex segmentation with coupled surfaces via level set methods, where the outer cortical surface is embedded as the zero level set of a high-dimensional dist...
