Epipolar geometry is a key point in computer vision and the fundamental matrix estimation is the only way to compute it. This article surveys several methods of fundamental matrix estimation which have been classified into linear methods, iterative methods and robust methods. All of these methods have been programmed and their accuracy analysed using real images. A summary, accompanied with experimental results, is given

El problema del tráfico de estupefacientes se ha convertido no solo en un dificultad para los países productores y consumidores, sino también para países de paso que a su vez se convierten en consumidores. Así la frontera entre Brasil y Colombia se ha convertido en objetivo para la lucha contra las drogas, usando herramientas como la interdicción aérea.

One of the techniques used to detect faults in dynamic systems is analytical redundancy. An important difficulty in applying this technique to real systems is dealing with the uncertainties associated with the system itself and with the measurements. In this paper, this uncertainty is taken into account by the use of intervals for the parameters of the model and for the measurements. The method that is proposed in this paper checks the consistency between the system's behavior, obtained from the measurements, and the model's behavior; if they are inconsistent, then there is a fault. The problem of detecting faults is stated as a quantified real constraint satisfaction problem, which can be solved using the modal interval analysis (MIA). MIA is used because it provides powerful tools to extend the calculations over real functions to intervals. To improve the results of the detection of the faults, the simultaneous use of several sliding time windows is proposed. The result of implementing this method is semiqualitative tracking (SQualTrack), a fault-detection tool that is robust in the sense that it does not generate false alarms, i.e., if there are false alarms, they indicate either that the interval model does not represent the system adequately or that the interval measurements do not represent the true values of the variables adequately. SQualTrack is currently being used to detect faults in real processes. Some of these applications using real data have been developed within the European project advanced decision support system for chemical/petrochemical manufacturing processes and are also described in this paper

Considering the difficulty in the insulin dosage selection and the problem of hyper- and hypoglycaemia episodes in type 1 diabetes, dosage-aid systems appear as tremendously helpful for these patients. A model-based approach to this problem must unavoidably consider uncertainty sources such as the large intra-patient variability and food intake. This work addresses the prediction of glycaemia for a given insulin therapy face to parametric and input uncertainty, by means of modal interval analysis. As result, a band containing all possible glucose excursions suffered by the patient for the given uncertainty is obtained. From it, a safer prediction of possible hyper- and hypoglycaemia episodes can be calculated

This a short presentation which introduces how models and modelling help us to solve large scale problems in the real world. It introduces the idea that dynamic behaviour is caused by interacting components in the system. Feedback in the system makes behaviour prediction difficult unless we use modelling to support understanding

En el presente proyecto se realizaron cuatro capítulos que corresponden a unos objetivos específicos; en el primer capítulo, se abordó un estudio analítico del origen, definición, características y naturaleza de las multas contractuales y de las cláusulas penales en el derecho privado, el objetivo fijado era establecer un marco teórico que fundamente los capítulos siguientes. Posteriormente, en el segundo capítulo, se realizó una identificación y evaluación del tratamiento que la legislación ha dado a las multas contractuales y cláusulas penales. En el tercer capítulo, se analizó un caso práctico donde se evidencia la dificultad en la aplicación de estas figuras por la Administración Pública, resaltada por la escasa e imprecisa legislación al respecto. Finalmente, en el último capítulo, se enumeraron y desarrollaron la problemática e interrogantes detectados a lo largo del proyecto, con la idea de establecer soluciones a los vacíos o incongruencias encontradas.
