The use of foreign language highlights, and possibly increases, the difficulties in the point of mathematical competence, but it can also be used to fix them. That is, making explicit the equivalence between formal and verbal language could improve symbolic language comprehension. Multilingual Formulae, an on -line resource at http://mformulae.epsem.upc.edu, is designed to give support in that direction, as equivalence is not found explicitly in textbooks or research papers. It contains sets of formulas with the corresponding written and oral version in several languages. The project, conducted by professors at the UPC Engineering School at Manresa Campus, is addressed to lecturers and students as a support to ensure effective communication when both Symbolic and Foreign language are used.

A real water network situated in Barcelona has been subdivided in zones which could contain a leakage. Two sensors measure pressures on two separated points of the network. A faulty fuzzy model for each zone and sensor is generated. Test data have been used for classification of leakages in order to evaluate how this methodology helps in leakage localization. Results are compared with another isolation methodology. All the work has been done using simulations carried out by EPANET connected with Matlab. FIR applications used are programmed in Matlab too.

This new approach based on both current and future health state estimates, provided by the prognosis module, takes into account the system’s health information in the control objectives. In this way, the control actions are generated to fulfill the control goals and, at the same time, to extend the life of the system components. To illustrate the performance of the proposed approach, a conveyor belt system that uses an AC electrical motor to move a cart from one end to the other is used.

The proposed algorithm is based on a criterion to minimize the energy of the control effort. To illustrate the methodology, the pitch angle of a laboratory helicopter is used as a model application with structured uncertainty. The results show that the design of robust controller can be formulated using an objective function and a number of restrictions that are developed as specifications.

This paper presents a low cost method to identify deviations in multiple component values using a precharacterisation of the impact of the deviations on the digital signatures for a set of input excitations. The method predicts several circuit under diagnosis (CUD) deviations by mapping them to a scalar value that indicates the discrepancy of the defective and golden digital signatures. Input excitation consists of a small set of sinusoidal signals with different frequencies. A digital signature is generated for every excitation set and compared to the golden response. The scalar discrepancy values are used to obtain the component deviations of the CUD. In order to generate the signatures, a CMOS monitor circuit has been designed and fabricated. The method is applied to the identification of capacitance deviations in a Biquad filter. Simulated results show the possibilities of the proposal Thu, 29 Dec 2011 12:18:05 GMT http://hdl.handle.net/2117/14355 2011-12-29T12:18:05Z Gómez Pau, Álvaro; Sanahuja Moliner, Ricard; Balado Suárez, Luz María; Figueras Pàmies, Joan no Analog circuits component diagnosis is a challenging task requiring expensive resources.

Este nuevo grado tiene por objetivo formar profesionales con un perfil generalista e integrador en el ámbito de las tecnologías electrónica, informática y de comunicaciones. Las materias de que consta el plan de estudios se focalizan en el estudio de dichas temáticas. En la elaboración de dicho plan de estudios, se consideró necesario introducir dos asignaturas, denominadas Tecnologías Complementarias 1 y 2, en las cuales se pretende aportar conocimientos relacionados la tecnología en general. Concretamente, se pretenden abordar algunos conocimientos del ámbito industrial y del ámbito social, así como, metodologías de trabajo individual y colectivo.
