LMGC90: a Contact Dynamics open source code for the simulation of granular asteroid with realistic regolith shapes. Application to the accretion process [PDF]
EPJ Web of Conferences, 2021 Granular asteroids are naturally occurring gravitational aggregates (rubble piles) bound together by gravitational forces. For this reason, it is reasonable to use the theoretical concepts and numerical tools developed for granular media to study them ...

Computing the vertices of tropical polyhedra using directed hypergraphs [PDF]
, 2013 We establish a characterization of the vertices of a tropical polyhedron defined as the intersection of finitely many half-spaces. We show that a point is a vertex if, and only if, a directed hypergraph, constructed from the subdifferentials of the ...

A polyhedral approach to the generalized minimum labeling spanning tree problem
EURO Journal on Computational Optimization, 2019 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.

A Polyhedral Approach for Graph Coloring1
Electronic Notes in Discrete Mathematics, 2001 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
Complexity, 2020 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
Algorithms, 2019 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 ...

MODERN SURVEILLANCE RADAR FOR AIR TRAFFIC CONTROL [PDF]
Fiabilitate şi Durabilitate, 2020 . In this paper, we focus on the approach of increasing RCS, therefore the size of RCS also includes the fact that not all radiated energy will reach the target.

A polyhedral approach to the rural postman problem
European Journal of Operational Research, 1994 [EN] In this paper we study the polyhedron associated with the Rural Postman Problem (RPP). Because the RPP is NP-hard, we cannot expect to find a complete description of the rural postman polyhedron of a general graph, but a partial knowledge of such a description frequently proves to be useful for both theoretical and computational purposes.
