LE FAIT NATIONAL AU SAHARA OCCIDENTAL
Studia Universitatis Babeş-Bolyai. Studia Europaea, 2020 The National Phenomenon in Western Sahara. This article analyses the Western Sahraouian nation from the perspective of its nationalist efforts, which, in derivative interaction with its enemies, rely on revolutionary cultural production.

Morphing Triangle Contact Representations of Triangulations
Discrete & Computational Geometry, 2023 AbstractA morph is a continuous transformation between two representations of a graph. We consider the problem of morphing between contact representations of a plane graph. In an $${\mathcal {F}}$$ F -contact representation of a plane graph G, vertices are realized by internally disjoint elements from a family ...

Contact and Intersection Representations [PDF]
, 2005 A necessary and sufficient condition is given for a connected bipartite graph to be the incidence graph of a family of segments and points. We deduce that any 4-connected 3-colorable plane graphs is the contact graphs of a family of segments and that any 4-colored planar graph without induced C4 using 4 colors is the intersection graph of a family of ...

Morphing Contact Representations of Graphs
CoRR, 2019 We consider the problem of morphing between contact representations of a plane graph. In an $\mathcal F$-contact representation of a plane graph $G$, vertices are realized by internally disjoint elements from a family $\mathcal F$ of connected geometric objects. Two such elements touch if and only if their corresponding vertices are adjacent.

Proportional Contact Representations of Planar Graphs [PDF]
Journal of Graph Algorithms and Applications, 2012 Summary: We study contact representations for planar graphs, with vertices represented by simple polygons and adjacencies represented by point-contacts or side-contacts between the corresponding polygons. Specifically, we consider proportional contact representations, where pre-specified vertex weights must be represented by the areas of the ...

Laboratory measurements and model sensitivity studies of dust deposition ice nucleation [PDF]
Atmospheric Chemistry and Physics, 2012 We investigated the ice nucleating properties of mineral dust particles to understand the sensitivity of simulated cloud properties to two different representations of contact angle in the Classical Nucleation Theory (CNT).

Contact Representations of Graphs in 3D [PDF]
, 2015 We study contact representations of graphs in which vertices are represented by axis-aligned polyhedra in 3D and edges are realized by non-zero area common boundaries between corresponding polyhedra. We show that for every 3-connected planar graph, there exists a simultaneous representation of the graph and its dual with 3D boxes. We give a linear-time

Topological Representation of Contact Lattices [PDF]
, 2006 The theory of Boolean contact algebras has been used to represent a region based theory of space. Some of the primitives of Boolean algebras are not well motivated in that context. One possible generalization is to drop the notion of complement, thereby weakening the algebraic structure from Boolean algebra to distributive lattice.

Les représentations de l’amitié sur Facebook
Communication, 2016 The authors provide a reflection on the social representation of friendship, both offline and on Facebook. Their investigation seeks to understand and compare Facebook users' definitions of friendship in everyday life and online.

Universal representations of evaporation modes in sessile droplets. [PDF]
PLoS ONE, 2017 In this work, we provide a simple method to represent the contact line dynamics of an evaporating sessile droplet. As a droplet evaporates, two distinct contact line dynamics are observed.
