Desde el ICE de la UPC se ha planteado una nueva formación dirigida a todo el profesorado basada en la adquisición de competencias docentes. Uno de los módulos de formación puesto en marcha trabaja la adquisición de la competencia interpersonal. Hasta la fecha se han realizado dos cursos a lo largo del año 2013. En este artículo se detallan los contenidos tratados en el módulo y las experiencias desarrolladas por algunos de los profesores que lo pusieron en práctica.
Promoted by the ICE of the UPC has been set a new training for all teachers based on the acquisition of teaching skills. One of the started training modules works the acquirement of interpersonal competence. For the time being there have been two courses, both developed throughout 2013. This article describes the content covered in the module and the experiences which were carried out by some of the teachers who implemented it.

Colored Ray configurations

We study the cyclic sequences induced at in nity by pairwise-disjoint colored rays with apices on a given bal- anced bichromatic point set, where the color of a ray is inherited from the color of its apex. We derive a lower bound on the number of color sequences that can be realized from any xed point set. We also examine se- quences that can be realized regardless of the point set and exhibit negative examples as well. In addition, we provide algorithms to decide whether a sequence is re- alizable from a given point set on a line or in convex position

A faster algorithm to compute the visibility map of a 1.5D terrain
Löffler, Maarten; Saumell, Maria; Silveira, Rodrigo Ignacio
Given a 1.5D terrain, i.e., an x -monotone polygonal line in R 2 with n vertices, and 1 m n viewpoints placed on some of the terrain vertices, we study the problem of computing the parts of the terrain that are visible from at least one of the viewpoints. We present an algorithm that runs in O ( n + m log m ) time. This improves over a previous algorithm recently proposed

Region-based approximation of probability distributions (for visibility between imprecise points among obstacles)
Buchin, Kevin; Kostitsyna, Irina; Löffler, Maarten; Silveira, Rodrigo Ignacio
Let p and q be two imprecise points, given as prob- ability density functions on R 2 , and let R be a set of n line segments in R 2 . We study the problem of approximating the probability that p and q can see each other; that is, that the segment connecting p and q does not cross any segment of R . To solve this problem, we approximate each density function by a weighted set of polygons; a novel approach to dealing with probability density functions in computational geometry

Order types and cross-sections of line arrangements in R^3
Aichholzer, Oswin; Fabila-Monroy, Ruy; Hurtado Díaz, Fernando Alfredo; Pérez Lantero, Pablo; Ruiz Vargas, Andrés; Urrutia Galicia, Jorge; Vogtenhuber, Birgit
We consider sets L = {l1,...., ln} of n labeled lines in general position in R3, and study the order types of point sets fp1; : : : ; png that stem from the intersections of the lines in L with (directed) planes II, not parallel to any line of L, i.e., the proper cross-sections of L.
As a main result we show that the number of different order types that can be obtained as cross-sections of L is O(n9), and that this bound is tight.

Geometric Biplane Graphs II: Graph Augmentation
Hurtado Díaz, Fernando Alfredo; Garcia Olaverri, Alfredo Martin; Korman Cozzetti, Matias; Matos, Inés P.; Saumell, Maria; Silveira, Rodrigo Ignacio; Tejel Altarriba, Francisco Javier; Tóth, Csaba D.
We study biplane graphs drawn on a nite point set
S
in the plane in general position.
This is the family of geometric graphs whose vertex set is
S
and which can be decomposed
into two plane graphs. We show that every su ciently large point set admits a 5-connected
biplane graph and that there are arbitrarily large point sets that do not admit any 6-
connected biplane graph. Furthermore, we show that every plane graph (other than a
wheel or a fan) can be augmented into a 4-connected biplane graph. However, there are
arbitrarily large plane graphs that cannot be augmented to a 5-connected biplane graph
by adding pairwise noncrossing edges.

Terrain visibility with multiple viewpoints
Hurtado Díaz, Fernando Alfredo; Löffler, Maarten; Matos, Inés P.; Sacristán Adinolfi, Vera; Saumell, Maria; Silveira, Rodrigo Ignacio; Staals, Frank
We study the problem of visibility in polyhedral terrains in the presence of multiple viewpoints. We consider three fundamental visibility structures: the visibility map, the colored visibility map, and the Voronoi visibility map. We study the complexity of each structure for both 1.5D and 2.5D terrains, and provide efficient algorithms to construct them. Our algorithm for the visibility map in 2.5D terrains improves on the only existing algorithm in this setting.

LD-graphs and global location-domination in bipartite graphs
Hernando Martín, María del Carmen; Mora Giné, Mercè; Pelayo Melero, Ignacio Manuel
A dominating setS of a graph G is a locating-dominating-set, LD-set for short, if every vertex v not in S is uniquely determined by the set of neighbors of v belonging to S. Locating-dominating sets of minimum cardinality are called LD - codes
and the cardinality of an LD-code is the
location-domination number
,
¿
(
G
).
An LD-set
S
of a graph
G
is
global
if it is an LD-set for both
G
and its complement,
G
. One of the main contributions of this work is the definition of the
LD-graph
,an
edge-labeled graph associated to an LD-set, that will be very helpful to deduce some
properties of location-domination in graphs. Concretely, we use LD-graphs to study
the relation between the location-domination number in a bipartite graph and its
complement
