[EN] Search of visualization alternatives to address the shortcomings of the current systems of representation and management of software requirements. Our proposal is based on the use of simplification and contextualization ...

[EN] We survey known results concerning how the conjugacy classes contained in a normal subgroup and their sizes exert an influence on the normal structure of a finite group. The approach is mainly presented in the framework ...

[EN] The existence and, if applicable, the location of paths with given properties is a topic in graph theory. One of these problems is to find routes through all points, only once, starting and ending at the same node. ...

Let G be a finite group and let N be a normal subgroup of G. We attach to N two graphs ΓG(N) and Γ∗ G(N) related to the conjugacy classes of G contained in N and to the set of primes dividing the sizes of these classes, ...

[EN] In this paper we show how modeling helps us to motivate the Graph Theory's students. We use the well-known game of “rock, paper, scissors” and its generalizations to show the applicability of mathematical concepts studied.

[ES] En este trabajo se describe una metodología para el estudio de las probabilidades de sucesos independientes en la asignatura Instrumentos de Estadística y Simulación, de segundo curso del Grado en Ciencias Ambientales ...

[EN] Advances in three-dimensional (3D) acquisition systems have introduced this technology to more fields of study, such as archaeology or architecture. In the architectural field, scanning a building is one of the first ...

[EN] In this paper we analyze the computational complexity of transportation infrastructure network design problems, in the presence of a competing transportation mode. Some of these problems have previously been introduced ...

[ES] Las enfermedades cardiovasculares se han convertido en la primera causa de fallecimientos en México y en el mundo. La medición de la íntima-media carotídea y del diámetro de la luz humeral en imágenes de ultrasonido, ...
