Upward Geometric Graph Embeddings into Point Sets [PDF]
We study the problem of characterizing the directed graphs with an upward straight-line embedding into every point set in general or in convex position. We solve two questions posed by Binucci et al. [Computational Geometry: Theory and Applications, 2010].

Point-Set Embedding of Trees with Edge Constraints [PDF]
Given a graph G with n vertices and a set S of n points in the plane, a point-set embedding of G on S is a planar drawing such that each vertex of G is mapped to a distinct point of S. A geometric point-set embedding is a point-set embedding with no edge bends. This paper studies the following problem: The input is a set S of n points, a planar graph G

Embedding and similarity search for point sets under translation [PDF]
Pattern matching in point sets is a well studied problem with numerous applications. We assume that the point sets may contain outliers (missing or spurious points) and are subject to an unknown translation. We define the distance between any two point sets to be the minimum size of their symmetric difference over all translations of one set relative ...

An Efficient Class-Constrained DBSCAN Approach for Large-Scale Point Cloud Clustering
To better interpret the scene and facilitate the subsequent processing of large-scale point cloud, clustering is often implemented in the preprocessing stage.

A reversible database watermarking method non-redundancy shifting-based histogram gaps
In relational databases, embedding watermarks in integer data using traditional histogram shifting method has the problem of large data distortion. To solve this problem, a reversible database watermarking method without redundant shifting distortion is ...

A Unified Framework for Nonrigid Point Set Registration via Coregularized Least Squares
This paper describes a method for performing nonrigid point set registration on data with different kinds of degradation (deformation, occlusion, noise, and outliers).

Many different precursors are known, but not all of which are effective, i.e., giving enough time to take preventive measures and with a minimum number of false early warning signals.

Dialectics of complexity, emergence and management
The article is devoted to the dialectical analysis of such fundamental essences of modern organizations as complexity, emergence and management. It considers approaches to the quantitative assessment of complexity as a constructive feature of the system,
