El projecte consisteix en analitzar, dissenyar i desenvolupar un sistemaestèreo binocular (format per dues càmeres) sobre un suport que ofereixi la mobilitat iportabilitat necessària per utilitzar-lo de forma independent, és a dir, sense necessitat deconnexió a un ordinador, ja que normalment, els sistemes de visió per computador solenincorporar un ordinador amb un frame grabber (placa de captura d’imatges). Per a dur a terme elsistema estèreo més adient, s’analitzaran els requeriments necessaris, s’estudiaran diferentsalternatives, i finalment, es desenvoluparà i es demostrarà el funcionament del sistema en qüestió

The effect of openness and trade orientation on economic growth remains a highly contentious issue in the literature. Trade facilitates the spread of knowledge and the adoption of more advanced and efficient technologies, which hastens total factor productivity (TFP) growth and, hence, per capita income. New technologies that spread through trade require a sufficiently skilled labour force to adapt them to the domestic productive environment. Thus, openness and human capital accumulation will lead to TFP growth and the greater the complementarity between both variables, the higher the TFP growth. This paper discusses the implications of these assumptions and tests their empirical validity, using a pool of data for manufacturing industry in Spanish regions in a period in which both the stock of human capital and openness experienced a notable increase.

Applied studies on the relationship between geography and technological innovation for United States, Germany, France and Italy have shown the positive effects that academic research exerts on the innovate output of firms at spatial level. The purpose of this paper is to look for new evidence on the possible effects of the university research for the case of Spain. To do so, within the framework of a Griliches-Jaffe knowledge production function, and using panel data and count models, the relationship between innovate inputs and patents, in the case of the Spanish regions is explored

This paper studies the output effects, transition costs and the change in pension benefits derived from the substitution of the current unfunded pension system by a fully funded pension system financed through mandatory savings.These effects are estimated by using reduced versions of the neoclassical and endogenous growth frameworks. Because of the greater capital accumulation during the transition phase, final output increases by 23,6% (neoclassicalframework); and a 24,5-31,5% (endogenous growth framework). The initial revenue loss for the government would represent a 4,8% of the GDP, raising very slowly during the transition period. Given the new growth rates, rates of return ofphysical capital, and financial intermediation costs, we have that the capitalization pension benefits obtained by all 30-contribution-year worker would be more than twice than those that guarantee the financial sustainability of thepublic pension system

[spa]La tutoría entre iguales ha adquirido un interés creciente en la institución universitaria dentro de la reforma de la educación superior impulsada en las dos últimas décadas. En este contexto, están siendo exploradas las relacio-nes posibles entre el aprendizaje formal y otros tipos diferentes de aprendizaje que se habían mantenido ajenos a la tradición universitaria. Es con la consideración del aprendizaje informal, y en relación con las teorías de las co-munidades de práctica y del aprendizaje situado, que cobra especial relieve la tutoría entre iguales. Este artículo es un estudio teórico sobre dicho recurso didáctico que se centra en dos asuntos fundamentales. Por un lado, el dilu-cidar el complejo problema terminológico que la afecta. Por otro, el subrayar la importancia de sus aportaciones específicas al aprendizaje de los estudiantes. Los dos son esenciales para reivindicar su singularidad y la relevan-cia de sus resultados y, acto seguido, para impulsar su meditada integración en la enseñanza universitaria.

Las competencias se han convertido en la piedra angular de la reforma de los sistemas educativos; también en la enseñanza universitaria. En este último caso, el proyecto Tuning ha desempeñado un papel de extraordinaria relevancia a nivel internacional y ha suscitado tantas adhesiones inquebrantables como críticas demoledoras. Este artículo parte de una lectura bien pegada a los textos del proyecto y persigue un examen crítico de su noción de competencia. Para ello, se prestará atención a los aspectos más destacados que afectan a la naturaleza y a los elementos constitutivos de las competencias ¿en ese plural recurrente en Tuning¿ en relación con el proceso educativo y el educando. También será objeto de consideración el contexto político y económico en el que surge el proyecto, a partir del cual se establecen sus presupuestos, su finalidad y sus objetivos. Todo esto será fundamental para calibrar el impacto y la evolución del proyecto en el proceso de reforma de la educación superior.
