Evenly Convex Credal Sets
An evenly convex credal set is a set of probability measures that is evenly convex; that is, a set that is an intersection of open halfspaces. An evenly convex credal set can for instance encode preference judgments through strict and non-strict inequalities such as P (A) > 1/2 and P (A) ≤ 2/3. This paper presents an axiomatization of evenly convex sets from preferences, where we introduce a ne...
متن کاملCreating Evenly-spaced Streamlines of Arbitrary Density ?
This paper presents a new evenly-spaced streamlines placement algorithm to visualize 2D steady ows. The main technical contribution of this work is to propose a single method to compute a wide variety of ow eld images, ranging from texture-like to hand-drawing styles. Indeed the control of the density of the eld is very easy since the user only needs to set the separating distance between adjac...
متن کاملCharacterizations of Quasiconvex Functions and Pseudomonotonicity of Subdifferentials
In this paper we introduce the concepts of quasimonotone maps and pseudoconvex functions. Moreover, a notion of pseudomonotonicity for multi mappings is introduced; it is shown that, if a function f is continuous, then its pseudoconvexity is equivalent to the pseudomonotonicity of its generalized subdifferential in the sense of Clarke and Rockafellar and prove that a lower semicontinuous functi...
متن کاملInteractive view-driven evenly spaced streamline placement
This paper presents an Interactive View-Driven Evenly Spaced Streamline placement algorithm (IVDESS) for 3D explorative visualization of large complex planar or curved surface flows. IVDESS rapidly performs accurate streamline integration in 3D physical space, i.e., the flow field, while achieving high quality streamline density control in 2D view space, i.e., the output image. The corresponden...
متن کاملAdaptive Polynomial Interpolation on Evenly Spaced Meshes
The problem of oscillatory polynomial interpolants arising from equally spaced mesh points is considered. It is shown that by making use of adaptive approaches that the oscillations may be contained and that the resulting polynomials are data bounded and monotone on each interval. This is achieved at the cost of using a different polynomial on each sub-interval. Computational results for a numb...
