Motion field and optical flow: qualitative properties
IEEE Transactions on Pattern Analysis and Machine Intelligence, 1989It is shown that the motion field the 2-D vector field which is the perspective projection on the image plane of the 3-D velocity field of a moving scene, and the optical flow, defined as the estimate of the motion field which can be derived from the first-order variation of the image brightness pattern, are in general different, unless special ...

Abstract We continue here the study of entropy weak solutions to the hyperbolic system of conservation laws with small total variation. Owing to the uniqueness results proved in the previous chapter, all these solutions can be obtained as limits of front tracking approximations.

Qualitative Properties of Differential Equations.
1981Abstract : Research was carried out in several broad areas: existence theory for generalized differential equations and general linear boundary value problems for non linear differential equations; singular perturbation problems and the theory of asymptotic integration; and dynamical systems and skew-product flows.

Qualitative Properties of Muonic Hydrogen Metals
Physical Review Letters, 1969We calculate qualitatively the cohesive energy and density of metals which theoretically should condense in high-pressure systems containing high concentrations of muons and various isotopes of hydrogen. The resulting metallic forms are found to be thermally superstable suggesting that they may perhaps exist briefly and in small quantities in some ...

Gradient flows II: Qualitative properties
2009Theorem 23.19 provides an interpretation of (24.1) as a gradient flow in the Wasserstein space P2(M). What do we gain from that information? A first possible answer is a new physical insight.

Qualitative properties of a niche-model
Mathematics and Computers in Simulation, 1999Abstract Within the framework of ecological systems analysis, the potential of niche formation plays an essential role, particularly in relation to the conditions of permanence or extinction of individual species. In this realm the model developed by Greve [Helgolander Meeresuntersuchungen 49, (1995) 811–820] in his study of possibilities of ...

Qualitative Properties of Foliations on Closed Surfaces
Journal of Dynamical and Control Systems, 2000The aim of this paper is to present a survey of the results obtained by the author (and his collaborators) during the preceding 10 years, on the theory of qualitative properties of singular foliations on closed surfaces. The author presents several important basic results on the development of the theory, from its origin until recent times (he ...

Qualitative properties and predictability of evolutions
2010In the previous chapter we already met various types of evolutions, including stationary and periodic ones. In the present chapter we investigate these evolutions more in detail and we also consider more general types. Here qualitative properties are our main interest.

Verifying Qualitative Properties of Probabilistic Programs
2004In this chapter, we present procedures for checking linear temporal logic and automata specifications of sequential and concurrent probabilistic programs. We follow two different approaches: For LTL and sequential probabilistic programs, our method proceeds in a tableau style fashion, while the remaining procedures are based on automata theory.
