From the large choice of wavelets proposed, Morlet’s wavelet has been selected. We show scalograms (squared modulus of the wavelet transform) of EEG signals during a seizure and also healthy persons’ EEGs. On viewing scalograms one can realise there are differences between healthy and unwell patients. These characteristics appear to be of diagnostic value.

El objetivo era desarrollar herramientas que faciliten al alumno el aprendizaje de los conceptos básicos de la asignatura y facilitar al profesor la explicación de esa materia. En primer lugar, se han evaluado los conceptos de la asignatura que se prestan a su aprendizaje mediante materiales multimedia, para posteriormente desarrollarlo mediante esquemas y un tutorial interactivo. Las unidades temáticas se han desarrollado en Power Point y el tutorial interactivo con el lenguaje de programación MATLAB. La primera versión del tutorial y de las unidades temáticas se ha evaluado por un grupo reducido de alumnos de Ingeniería de Telecomunicación y, en base a sus sugerencias, se han realizado cambios. En el curso 2004 se ha seguido evaluando y perfeccionando el programa desarrollado

Theoretical background and preliminary results in two young male, defectual schizophrenic patients (paranoid type) are here presented. Basic symptoms were explored by means of the Frankfurt Complaint Questionnaire of FBF (Frankfurter Beschwerde-Fragebogen) and the Bonn Scale for the Assessment of Basic Symptoms of Gross et al. Possible relationships between cerebral complexity and basic symptoms are discussed. It is concluded that the ARG is a valuable technique to measure the patient's cognitive potential as well as his complexity level (or cerebral chaotic dynamic complexity). Finally, it is hypothesized that defectual psychotic patients genérate more rigid and rhythmic series than control groups. Further work must be done in this new research field.

These people usually have great impairments which prevent them from performing their normal daily activities. For our society, this fact means a great effort in cares and specialized attention that, in most cases,

This approach was valid in legacy GSM networks. However, current Universal Mobile Telecommunications System networks deal with different resource consumption services such as voice, video call or data, and different limiting resources such as baseband processing capacity, transmission link capacity to the RNC, or spreading code tree. Operators need models to decide which resource must be upgraded, according to the demand of the services, in order to achieve expected overall service accessibility (i.e., the complementary of blocking probability). Network operation requires detecting when degradation is due to a lack of resources or to a hardware malfunction. Also, when operators need to prevent blockage in a high-capacity demanding event (for which they only have traffic predictions for each service) it is far from trivial to dimension resources. We have implemented a Kaufman Roberts approach to...
