The problem of querying heterogeneous geospatial databases in distributed environment can be resolved through alignment of ontologies. That is establishing mappings between related concepts in the different ontologies without combining them. Ontology alignment facilitates the propagation of a single query written in terms of a specific ontology to other databases in terms of their own ontologie...

Given a sub-hyperbolic semi-rational branched covering which is not CLH-equivalent a rational map, it must have the non-empty canonical Thurston obstruction. By using this canonical Thurston obstruction, we decompose this dynamical system in this paper into several sub-dynamical systems. Each of these subdynamical systems is either a post-critically finite type branched covering or a sub-hyperb...

In this paper, we propose a new method to upsample a depth map for 3D video acquisition. The proposed method is based on Markov random fields. The low-resolution depth values are used for data term and the high-resolution color data are exploited for smoothness term. Especially, we apply semi-global energy minimization to reduce computational time. Experimental results show that the proposed me...

Most learning algorithms for factor graphs require complete inference over the dataset or an instance before making an update to the parameters. SampleRank is a rank-based learning framework that alleviates this problem by updating the parameters during inference. Most semi-supervised learning algorithms also rely on the complete inference, i.e. calculating expectations or MAP configurations. W...

Using only basic topological properties of real algebraic sets and regular morphisms we show that any injective regular self-mapping of a real algebraic set is surjective. Then we show that injective morphisms between germs of real algebraic sets define a partial order on the equivalence classes of these germs divided by continuous semi-algebraic homeomorphisms. We use this observation to deduc...

For a zero-dimensional topological space X and totally ordered field F with interval topology, Cc(X, F) denotes the ring consisting of field-valued continuous functions countable range on X. This article aims to study investigate rings quotients Cc(X,F). Qc(X,F) (resp. qc(X,F)), maximal classical) Cc(X,F) as modified analogue Q(X) q(X)), C(X) are characterized. It is proved that Qc(S), subring ...

The Method of Characteristics is examined as a tool for making fluid simulation more efficient and effective in VFX production. A mathematical framework for a Characteristic Map is shown to be a generalization of the previous methods called Gridless Advection and Semi-Lagrangian Mapping. We demonstrate that the Characteristic Map can be used to modify a fluid flow post-simulation, including inj...

Visualization of geographic information in the form of maps has been established for centuries. Depending on the scale of the map the level of detail of displayed objects must be adapted in a generalization process. Be it done manually or (semi-)automatically, generalization methods usually produce a map at a single target scale. This is a well-studied field, surveyed, for example, by Weibel an...

We investigate bi–Hamiltonian structures and related mKdV hierarchy of solitonic equations generated by (semi) Riemannian metrics and curve flow of non–stretching curves. The corresponding nonholonomic tangent space geometry is defined by canonically induced nonlinear connections, Sasaki type metrics and linear connections. One yields couples of generalized sine–Gordon equations when the corres...
