Algorithmic Perception of Vertices in Sketched Drawings of Polyhedral Shapes [PDF]
In this article, visual perception principles were used to build an artificial perception model aimed at developing an algorithm for detecting junctions in line drawings of polyhedral objects that are vectorized from hand-drawn sketches. The detection is

A polyhedral approach to the generalized minimum labeling spanning tree problem
The minimum labeling spanning tree problem (MLSTP) is a combinatorial optimization problem that consists in finding a spanning tree in a simple graph G, in which each edge has one label, by using a minimum number of labels.

Minimal Bending Energies of Bilayer Polyhedra [PDF]
Motivated by recent experiments on bilayer polyhedra composed of amphiphilic molecules, we study the elastic bending energies of bilayer vesicles forming polyhedral shapes.

A Polyhedral Approach for Graph Coloring1
Abstract Abstract We present an approach based on an integer programming formulation of the graph coloring problem. Our goal is to develop a model that removes some symmetrical solutions obtained by color permutations. We study the problem from a polyhedral point of view and determine some families of facets of the associated polytope.

Constrained Uncertain System Stabilization with Enlargement of Invariant Sets
An enhanced method able to perform accurate stability of constrained uncertain systems is presented. The main objective of this method is to compute a sequence of feedback control laws which stabilizes the closed-loop system.

Aiding Dictionary Learning Through Multi-Parametric Sparse Representation
The ℓ 1 relaxations of the sparse and cosparse representation problems which appear in the dictionary learning procedure are usually solved repeatedly (varying only the parameter vector), thus making them well-suited to a multi-parametric ...

Optimizing I/O for Big Array Analytics [PDF]
Big array analytics is becoming indispensable in answering important scientific and business questions. Most analysis tasks consist of multiple steps, each making one or multiple passes over the arrays to be analyzed and generating intermediate results ...
