A Communicative Approach to Testing : II parte.

Se recogen una serie de actividades en inglés a modo de pruebas de evaluación sobre contenidos interdisciplinares relativos al medio ambiente. El objetivo es relacionar la lengua inglesa con otras asignaturas, potenciando al mismo tiempo la capacidad lingüístico-comunicativa de los alumnos en otro idioma (investigación, análisis de datos, deducciones lógicas, argumentación, etc). El material utilizado son artículos de periódicos y revistas, fragmentos de programas de televisión, cómics, etc y va dirigido a jóvenes del nuevo bachillerato..

Bringing history to life : a pedagogical approach to cultural studies. 'Traer la historia a la vida : un acercamiento pedagógico a los estudios culturales'.

Se muestra un ejemplo práctico de un proyecto didáctico que presenta los hechos históricos con un estilo periodístico. Se busca de esta forma aumentar el interés por los hechos historicos entre los alumnos y facilitar su asimilación del conocimiento histórico.

A Communicative Approach to Testing. 'Una aproximación comunicativa a la evaluación'.

El presente documento realiza un estudio sobre los distintos criterios y técnicas de evaluación que se pueden aplicar al conocimiento de la asignatura de lengua inglesa por parte de los alumnos. Se valorará la participación de éstos en conversaciones breves, la redacción de textos sencillos con una estructura lógica, el establecimiento de comparaciones para establecer semejanzas y diferencias entre objetos, personas, etc., la capacidad para comprender textos sencillos... Los contenidos están dirigidos a alumnos de tercero y cuarto curso de la Educación Secundaria Obligatoria.

La evaluación desde una perspectiva metacognitiva = Metacognitive approach to evaluation.

A new efficient approach to the direct restricted active space self-consistent field method

An implicitly parallel method for integral-block driven restricted active space self-consistent field (RASSCF) algorithms is presented. The approach is based on a model space representation of the RAS active orbitals with an efficient expansion of the model subspaces. The applicability of the method is demonstrated with a RASSCF investigation of the first two excited states of indole

An approach to coded structured light to obtain three dimensional information

The human visual ability to perceive depth looks like a puzzle. We perceive three-dimensional spatial information quickly and efficiently by using the binocular stereopsis of our eyes and, what is mote important the learning of the most common objects which we achieved through living. Nowadays, modelling the behaviour of our brain is a fiction, that is why the huge problem of 3D perception and further, interpretation is split into a sequence of easier problems. A lot of research is involved in robot vision in order to obtain 3D information of the surrounded scene. Most of this research is based on modelling the stereopsis of humans by using two cameras as if they were two eyes. This method is known as stereo vision and has been widely studied in the past and is being studied at present, and a lot of work will be surely done in the future. This fact allows us to affirm that this topic is one of the most interesting ones in computer vision. The stereo vision principle is based on obtaining the three dimensional position of an object point from the position of its projective points in both camera image planes. However, before inferring 3D information, the mathematical models of both cameras have to be known. This step is known as camera calibration and is broadly describes in the thesis. Perhaps the most important problem in stereo vision is the determination of the pair of homologue points in the two images, known as the correspondence problem, and it is also one of the most difficult problems to be solved which is currently investigated by a lot of researchers. The epipolar geometry allows us to reduce the correspondence problem. An approach to the epipolar geometry is describes in the thesis. Nevertheless, it does not solve it at all as a lot of considerations have to be taken into account. As an example we have to consider points without correspondence due to a surface occlusion or simply due to a projection out of the camera scope. The interest of the thesis is focused on structured light which has been considered as one of the most frequently used techniques in order to reduce the problems related lo stereo vision. Structured light is based on the relationship between a projected light pattern its projection and an image sensor. The deformations between the pattern projected into the scene and the one captured by the camera, permits to obtain three dimensional information of the illuminated scene. This technique has been widely used in such applications as: 3D object reconstruction, robot navigation, quality control, and so on. Although the projection of regular patterns solve the problem of points without match, it does not solve the problem of multiple matching, which leads us to use hard computing algorithms in order to search the correct matches. In recent years, another structured light technique has increased in importance. This technique is based on the codification of the light projected on the scene in order to be used as a tool to obtain an unique match. Each token of light is imaged by the camera, we have to read the label (decode the pattern) in order to solve the correspondence problem. The advantages and disadvantages of stereo vision against structured light and a survey on coded structured light are related and discussed. The work carried out in the frame of this thesis has permitted to present a new coded structured light pattern which solves the correspondence problem uniquely and robust. Unique, as each token of light is coded by a different word which removes the problem of multiple matching. Robust, since the pattern has been coded using the position of each token of light with respect to both co-ordinate axis. Algorithms and experimental results are included in the thesis. The reader can see examples 3D measurement of static objects, and the more complicated measurement of moving objects. The technique can be used in both cases as the pattern is coded by a single projection shot. Then it can be used in several applications of robot vision. Our interest is focused on the mathematical study of the camera and pattern projector models. We are also interested in how these models can be obtained by calibration, and how they can be used to obtained three dimensional information from two correspondence points. Furthermore, we have studied structured light and coded structured light, and we have presented a new coded structured light pattern. However, in this thesis we started from the assumption that the correspondence points could be well-segmented from the captured image. Computer vision constitutes a huge problem and a lot of work is being done at all levels of human vision modelling, starting from a)image acquisition; b) further image enhancement, filtering and processing, c) image segmentation which involves thresholding, thinning, contour detection, texture and colour analysis, and so on. The interest of this thesis starts in the next step, usually known as depth perception or 3D measurement.
