El treball que es presenta a continuació és una anàlisi sobre la comunicació del ex entrenador del FC Barcelona, Josep Guardiola, i la forma en com s'expressa i utilitza el seu discurs per impactar a tots els seus públics. Partint del seu discurs comunicatiu com a base del treball, analitzarem també el què i el com de la seva comunicació, la seva actitud amagada darrere les seves paraules, com interactua amb els seus interlocutors o el reflex de les seves expressions corporals. Descobrirem per què és actualment un dels màxims referents quan parlem de comunicació i influència en el mon del esport. Comprovarem per què la figura del tècnic ha aconseguit la notorietat que té i ha arribat al referent comunicatiu actual.

En el presente trabajo presentamoslos mecanismos de persuasión de chinos y españoles basándonos en los seis principios de influencia propuestos por Cialdini, pero analizándolos desde una perspectiva pragmalingüística, teniendo en cuenta el uso de estrategias de cortesía, elementos de atenuación y elementos paralingüísticos y quinésicos. Hemos diseñado un cuestionario específicopartiendo de estos principios, cuyos resultados nos permite realizarun análisis cuantitativo. Comparando los mecanismos de ambos grupos,llegamos a la conclusión de que en el proceso de influencia social en estas dos culturas estos principios funcionan de manera parecida, pero no totalmente igual.

En els darrers anys, la criptografia amb corbes el.líptiques ha adquirit una importància creixent, fins a arribar a formar part en la actualitat de diferents estàndards industrials. Tot i que s'han dissenyat variants amb corbes el.líptiques de criptosistemes clàssics, com el RSA, el seu màxim interès rau en la seva aplicació en criptosistemes basats en el Problema del Logaritme Discret, com els de tipus ElGamal. En aquest cas, els criptosistemes el.líptics garanteixen la mateixa seguretat que els construïts sobre el grup multiplicatiu d'un cos finit primer, però amb longituds de clau molt menor. Mostrarem, doncs, les bones propietats d'aquests criptosistemes, així com els requeriments bàsics per a que una corba sigui criptogràficament útil, estretament relacionat amb la seva cardinalitat. Revisarem alguns mètodes que permetin descartar corbes no criptogràficament útils, així com altres que permetin obtenir corbes bones a partir d'una de donada. Finalment, descriurem algunes aplicacions, com són el seu ús en Targes Intel.ligents i sistemes RFID, per concloure amb alguns avenços recents en aquest camp.

En este artículo nos centramos en uno de los temas de la gramática española más complejos: la conjugación verbal. A partir de la obra de Samuel Gili Gaya (1961), Curso superior de sintaxis española, analizamos en obras gramaticales representativas de la segunda mitad del siglo XX el estudio de este tema considerando la presencia de las teorías de Gili Gaya. Con ello, pretendemos comprobar nuestra hipótesis inicial: las ideas lingüísticas de este autor suponen, en gran medida, la unión de la Gramática tradicional con enfoques posteriores.

Postmortem MRI (PMMR) examinations are seldom performed in legal medicine due to long examination times, unfamiliarity with the technique, and high costs. Furthermore, it is difficult to obtain access to an MRI device used for patients in clinical settings to image an entire human body. An alternative is available: ex situ organ examination. To our knowledge, there is no standardized protocol that includes ex situ organ preparation and scanning parameters for postmortem MRI. Thus, our objective was to develop a standard procedure for ex situ heart PMMR examinations. We also tested the oily contrast agent Angiofil® commonly used for PMCT angiography, for its applicability in MRI. We worked with a 3 Tesla MRI device and 32-channel head coils. Twelve porcine hearts were used to test different materials to find the best way to prepare and place organs in the device and to test scanning parameters. For coronary MR angiography, we tested different mixtures of Angiofil® and different injection materials. In a second step, 17 human hearts were examined to test the procedure and its applicability to human organs. We established two standardized protocols: one for preparation of the heart and another for scanning parameters based on experience in clinical practice. The established protocols enabled a standardized technical procedure with comparable radiological images, allowing for easy radiological reading. The performance of coronary MR angiography enabled detailed coronary assessment and revealed the utility of Angiofil® as a contrast agent for PMMR. Our simple, reproducible method for performing heart examinations ex situ yields high quality images and visualization of the coronary arteries.

The control of the right application of medical protocols is a key issue in hospital environments. For the automated monitoring of medical protocols, we need a domain-independent language for their representation and a fully, or semi, autonomous system that understands the protocols and supervises their application. In this paper we describe a specification language and a multi-agent system architecture for monitoring medical protocols. We model medical services in hospital environments as specialized domain agents and interpret a medical protocol as a negotiation process between agents. A medical service can be involved in multiple medical protocols, and so specialized domain agents are independent of negotiation processes and autonomous system agents perform monitoring tasks. We present the detailed architecture of the system agents and of an important domain agent, the database broker agent, that is responsible of obtaining relevant information about the clinical history of patients. We also describe how we tackle the problems of privacy, integrity and authentication during the process of exchanging information between agents.

L'objectiu d'aquest article és contribuir a l'estudi de la morfologia verbal catalana, en aquest cas amb dades relatives a la varietat nord-occidental. Les formes que forneixen la part descriptiva corresponen a mostres de producció oral obtingudes en informants de 3 -4, 6- 7 i 11- 12 anys, la qual cosa signi ca una descripció morfològica del període de desenvolupament lingüístic del nen. Pel que fa a la interpretació dels resultats es proposa una perspectiva d'anàlisi que inclou tant les consideracions que tenen a veure amb aspectes interns del llenguatge com amb els de caràcter extern.

La redacció d'aquest article parteix d'una re flexió de l'autora sobre aspectes metodològics aplicats en els treballs que estudien alguns dels aspectes de la morfologia verbal, a partir de les mancances detectades a l'hora d'iniciar la seva recerca personal en aquest camp. L'objectiu d'aquest article es concreta finalment en tres aspectes. En primer lloc, tenir una idea clara de la complexitat del concepte de verb i les seves implicacions com a objecte de recerca. En segon lloc valorar els avantatges i els desavantatges d'algunes de les tècniques més emprades en els treballs de base empírica en l'anàlisi de la morfologia verbal partint d'exemples reals i, en darrer lloc, apuntar algunes idees sobre qüestions que caldria estudiar de forma conjunta en una dimensió pragmàtica de l'ús verbal.

Key management has a fundamental role in secure communications. Designing and testing of key management protocols is tricky. These protocols must work flawlessly despite of any abuse. The main objective of this work was to design and implement a tool that helps to specify the protocol and makes it possible to test the protocol while it is still under development. This tool generates compile-ready java code from a key management protocol model. A modelling method for these protocols, which uses Unified Modeling Language (UML) was also developed. The protocol is modelled, exported as an XMI and read by the code generator tool. The code generator generates java code that is immediately executable with a test software after compilation.

The networking and digitalization of audio equipment has created a need for control protocols. These protocols offer new services to customers and ensure that the equipment operates correctly. The control protocols used in the computer networks are not directly applicable since embedded systems have resource and cost limitations. In this master's thesis the design and implementation of new loudspeaker control network protocols are presented. The protocol stack was required to be reliable, have short response times, configure the network automatically and support the dynamic addition and removal of loudspeakers. The implemented protocol stack was also required to be as efficient and lightweight as possible because the network nodes are fairly simple and lack processing power. The protocol stack was thoroughly tested, validated and verified. The protocols were formally described using LOTOS (Language of Temporal Ordering Specifications) and verified using reachability analysis. A prototype of the loudspeaker network was built and used for testing the operation and the performance of the control protocols. The implemented control protocol stack met the design specifications and proved to be highly reliable and efficient.

La característisca més notable dels sistemes flexius és la resistència que ofereixen a la tasca lingüística d'establir relacions entre morfs i morfemes. En sistemes d'aquesta classe, en efecte, les relacions esmentades són molt complexes, i fugen de la biunicitat pròpia dels sistemes aglutinants. Aclarir aquestes relacions, il·lustrant-les des de l'angle del verb català, i suggerir mecanismes formals per tractar-les dins un esquema generatiu constitueixen, de fet, els dos objectius fonamentals del present article.

Imaging in neuroscience, clinical research and pharmaceutical trials often employs the 3D magnetisation-prepared rapid gradient-echo (MPRAGE) sequence to obtain structural T1-weighted images with high spatial resolution of the human brain. Typical research and clinical routine MPRAGE protocols with ~1mm isotropic resolution require data acquisition time in the range of 5-10min and often use only moderate two-fold acceleration factor for parallel imaging. Recent advances in MRI hardware and acquisition methodology promise improved leverage of the MR signal and more benign artefact properties in particular when employing increased acceleration factors in clinical routine and research. In this study, we examined four variants of a four-fold-accelerated MPRAGE protocol (2D-GRAPPA, CAIPIRINHA, CAIPIRINHA elliptical, and segmented MPRAGE) and compared clinical readings, basic image quality metrics (SNR, CNR), and automated brain tissue segmentation for morphological assessments of brain structures. The results were benchmarked against a widely-used two-fold-accelerated 3T ADNI MPRAGE protocol that served as reference in this study. 22 healthy subjects (age=20-44yrs.) were imaged with all MPRAGE variants in a single session. An experienced reader rated all images of clinically useful image quality. CAIPIRINHA MPRAGE scans were perceived on average to be of identical value for reading as the reference ADNI-2 protocol. SNR and CNR measurements exhibited the theoretically expected performance at the four-fold acceleration. The results of this study demonstrate that the four-fold accelerated protocols introduce systematic biases in the segmentation results of some brain structures compared to the reference ADNI-2 protocol. Furthermore, results suggest that the increased noise levels in the accelerated protocols play an important role in introducing these biases, at least under the present study conditions.

Positron emission tomography (PET) data are commonly analyzed in terms of regional intensity, while covariant information is not taken into account. Here, we searched for network correlates of healthy cognitive function in resting state PET data. PET with [(18)F]-fluorodeoxyglucose and a test of verbal working memory (WM) were administered to 35 young healthy adults. Metabolic connectivity was modeled at a group level using sparse inverse covariance estimation. Among 13 WM-relevant Brodmann areas (BAs), 6 appeared to be robustly connected. Connectivity within this network was significantly stronger in subjects with above-median WM performance. In respect to regional intensity, i.e., metabolism, no difference between groups was found. The results encourage examination of covariant patterns in FDG-PET data from non-neurodegenerative populations.
