Applying recommendations to aligncompetences, methodology and assessment in Telematics, Computing and Electronic Engineering courses

The alignment between competences, teaching-learning methodologies and assessment is a key element of the European Higher Education Area. This paper presents the efforts carried out by six Telematics, Computer Science and Electronic Engineering Education teachers towards achieving this alignment in their subjects. In a joint work with pedagogues, a set of recommended actions were identified. A selection of these actions were applied and evaluated in the six subjects. The cross-analysis of the results indicate that the actions allow students to better understand the methodologies and assessment planned for the subjects, facilitate (self-) regulation and increase students’ involvement in the subjects.

Relations among several nuclear and electronic density functional reactivity indexes

A set of connections among several nuclear and electronic indexes of reactivity in the framework of the conceptual Density Functional Theory by using an expansion ofthe energy functional in terms of the total number of electrons and the normal coordinates within a canonical ensemble was derived. The relations obtained provided explicit links between important quantities related to the chemical reactivity of a system. This paper particularly demonstrates that the derivative of the electronic energy with respect to the external potential of a system in its equilibrium geometry was equal to the negative of the nuclear repulsion derivative with respect to the external potential

Investigation of defect formation and electronic transport in microcrystalline silicon deposited by hot-wire CVD

We have investigated doped and undoped layers of microcrystalline silicon prepared by hot-wire chemical vapour deposition optically, electrically and by means of transmission electron microscopy. Besides needle-like crystals grown perpendicular to the substrate's surface, all of the layers contained a noncrystalline phase with a volume fraction between 4% and 25%. A high oxygen content of several per cent in the porous phase was detected by electron energy loss spectrometry. Deep-level transient spectroscopy of the crystals suggests that the concentration of electrically active defects is less than 1% of the undoped background concentration of typically 10^17 cm -3. Frequency-dependent measurements of the conductance and capacitance perpendicular to the substrate surface showed that a hopping process takes place within the noncrystalline phase parallel to the conduction in the crystals. The parasitic contribution to the electrical circuit arising from the porous phase is believed to be an important loss mechanism in the output of a pin-structured photovoltaic solar cell deposited by hot-wire CVD.

Desenvolupament d'un sistema de transferència de software per una placa entrenadora

El departament d’electrònica i telecomunicacions de la Universitat de Vic ha dissenyat un conjunt de plaques entrenadores amb finalitat educativa. Perquè els alumnes puguin utilitzar aquestes plaques com a eina d’estudi, és necessari disposar d’un sistema de gravació econòmic i còmode. La major part dels programadors, en aquest cas, no compleixen amb aquests requeriments. L’objectiu d’aquest projecte és dissenyar un sistema de programació que utilitzi la comunicació sèrie i que no requereixi d'un hardware ni software específics. D’aquesta manera, obtenim una placa autònoma i un programador gratuït, de muntatge ràpid i simple d’utilitzar. El sistema de gravació dissenyat s’ha dividit en tres blocs. Per una banda, un programa que anomenem “programador” encarregat de transferir codi de programa des de l’ordinador al microcontrolador de la placa entrenadora. Per altra banda, un programa anomenat “bootloader”, situat al microcontrolador, permet rebre aquest codi de programa i emmagatzemar-lo a les direccions de memòria de programa corresponents. Com a tercer bloc, s’implementa un protocol de comunicació i un sistema de control d’errors per tal d’assegurar una correcta comunicació entre el “programador” i el “bootloader”. Els objectius d’aquest projecte s’han complert i per les proves realitzades, el sistema de programació ha funcionat correctament.

Electronic structure and properties of Cu2O

The structural and electronic properties of Cu2O have been investigated using the periodic Hartree-Fock method and a posteriori density-functional corrections. The lattice parameter, bulk modulus, and elastic constants have been calculated. The electronic structure of and bonding in Cu2O are analyzed and compared with x-ray photoelectron spectroscopy spectra, showing a good agreement for the valence-band states. To check the quality of the calculated electron density, static structure factors and Compton profiles have been calculated, showing a good agreement with the available experimental data. The effective electron and hole masses have been evaluated for Cu2O at the center of the Brillouin zone. The calculated interaction energy between the two interpenetrated frameworks in the cuprite structure is estimated to be around -6.0 kcal/mol per Cu2O formula. The bonding between the two independent frameworks has been analyzed using a bimolecular model and the results indicate an important role of d10-d10 type interactions between copper atoms.

El comentario de textos electrónicos = Commentary on electronic texts

When sat in front of a computer screen and keyboard, we read and write different kinds of texts (chats, blogs, websites,etc.) and do so differently (with links, photographs, icons, etc.). However, we still comment on as many texts as in the pastin both public and private spheres. After setting out some typical features of reading and writing electronic texts, we givesome examples of students' colloquial commentary out of school, list some of the commonest academic tasks and offersome ideas and make some recommendations for making progress in this field

Performance analysis and tuning in multicore environments

Performance analysis is the task of monitor the behavior of a program execution. The main goal is to find out the possible adjustments that might be done in order improve the performance. To be able to get that improvement it is necessary to find the different causes of overhead. Nowadays we are already in the multicore era, but there is a gap between the level of development of the two main divisions of multicore technology (hardware and software). When we talk about multicore we are also speaking of shared memory systems, on this master thesis we talk about the issues involved on the performance analysis and tuning of applications running specifically in a shared Memory system. We move one step ahead to take the performance analysis to another level by analyzing the applications structure and patterns. We also present some tools specifically addressed to the performance analysis of OpenMP multithread application. At the end we present the results of some experiments performed with a set of OpenMP scientific application.
