Pretende conduzir a sensibilidade do espectador para expandir a vivência de valores humanistas. Como suporte, revela-nos o empenho do artista por uma arte viva. A pesquisa se oferece como um fio condutor a quem se interessa pela ampliação do conceito de arte, e, ao mesmo tempo, se propõe a evidenciar, através do mergulho em alguns símbolos, as direções e paisagens do pensamento do artista. / The present study focuses on the Blackboard as an artistic object in the work of Joseph Beuys and aimes an aproximation with the observer. It wants to capture the interest of the spectator for the sensible paths proposed by the scribbles. It intends to drive the sensitivity of the spectator in order to expand the experience of humanistic values. As a support, the blackboard reveals the artist´s commitment to a living art, to life. The research offers itself as a guiding thread to those who are interested in the expansion of the concept of art. At the same time, it aims to evidence, through an immersion in some symbols, the directions and landscapes of the artist´s thought. / Não recebi financiamento

Context. The single blackboard architecture is widely used in the LTE application area. Despite its several benefits, this architecture limits synchronization possibilities of the developed systems and increases the signal operational latency. As a result the DSP (Digital Signal Processing) utilization is suboptimal. Objectives. In this thesis, we design a new architecture, which combines concepts of Multi-Blackboards and Pipes & Filters architectures, as a replacement for the current single blackboard architecture at Ericsson. The implementation of the new architecture makes the environment asynchronous. We evaluate the new architecture at simulated environment of Ericsson with 222225 connection items from 9000 base stations all over the world. Each connection item has a complete UE session and one of possible connection statuses, e.g. active, inactive, connected, DRX sleeping, postponed. These connection items can be from any country in the world. Methods. We design a new architecture for UPCUL component of LTE network based on analysis of real network data from Ericsson. We perform a case study to develop and evaluate the new architecture at Ericsson. Results. We evaluate the new architecture by performing a case study at Ericsson. The results of case study show that the new architecture not only increases DSP utilization by 35%, but also decreases signal operational latency by 53%, FO operation time by 20% and FO operation cycles by 20%. Also, the new architecture increases correctness performance. Conclusions.  We conclude that the new architecture increases DSP utilization and decreases the signal operational latency, therefore, improves performances of UPCUL component of LTE.  Due to time constraints, we only considered four LTE FOs (Function Objects) and relative signals. Future work should focus mainly on the other FOs and signals. We also analyze unconsidered FOs, and make an integration solution table which contains solutions to integrate these unconsidered FOs into the new architecture.  The second avenue for future work is to re-size the size of the two blackboard storages. We find out that the maximum memory size of needed UE sessions per sub-frame is only 1.305% of the memory size of all UE sessions (31650 bytes). So the memory size of blackboard storage should be adjusted on the basis of needed UE sessions instead of all UE sessions.

This study locates the Blackboard Learning Management System as a Technology Enhanced Learning tool within the bounds of the discipline of eLearning and aimed to interrogate the use of Blackboard for the purposes of teaching, learning and assessment in large classes. It is evident from the literature reviewed that changes in both Higher Education in the South Africa with regards to policy and legislation in addition to international shifts towards increased access and participation in a fast paced, ever-evolving knowledge-based economy, providing the context for this work. The theoretical framework for this study is not unidimensional due to the fact that the educational field of eLearning as an area of specialisation draws on a multitude of theories in terms of their utility value for instructional design of courses utilising Information and Communications Technology as a mode of delivery. This study was conducted within the bounds of an interpretivist paradigm as the researcher sought to focus on the use of Blackboard and the experiences of the lecturers and students involved in the implementation thereof. The research design for this study took the form of a case study and a multiple case method was employed. The researcher collected data through personal interviews conducted with participating lecturers, while student data was collected by means of a qualitative survey which was conducted through the Blackboard Learning Management System. The data was analyzed by means of a thematic analysis, consistent with the interpretive paradigm chosen for this study. The findings of this study revealed that Blackboard was utilised effectively in order to facilitate communication, access to course resources and promoted more efficient assessment processes. The implementation was however not without challenges many of which were systemic and focused on the lack of resources available to the students. The implications of using Blackboard for teaching and assessment of large classes include the use of the Learning Management System as part of a multimodal method of course delivery in an effort to reach the multitude of registered students both conceptually as well as electronically. The recommendations arising from this study include consideration on the part of the faculty for a unified approach in the use of Blackboard for communication as well as deployment of resources. Additionally, this study may form the foundation of further studies in this field, with a focus on the active engagement and training of lecturers in order to integrate traditional teaching methods with blended learning opportunities.

Cette thèse aborde la spécification et la réalisation de CELINE, outil de correction des erreurs basé sur une architecture multi-agents à deux niveaux : <BR> 1) Un système lourd, renfermant l'ensemble du savoir linguistique (multi-domaines par rapport à l'univers du discours), et générateur de systèmes individualisés. Les agents peuvent être considérés comme imparfaits ou partiellement inadaptés. Ils sont mis en concurrence par domaine d' expertise.<BR> 2) Un système léger implanté sur le site du rédacteur, système construit par apprentissage par le système central à partir des travaux de ce rédacteur.<BR> La spécification du système se construit tout au long des chapitres.<BR> La problématique de la correction des erreurs et la finalité de la conception d'un système de correction le plus automatique possible, avec des prises de décision à faible granularité reposant sur des critères multi-niveaux, nous entraînent vers un besoin de coopération justifiant une réalisation multi-agents.<BR> Une taxinomie des erreurs et des rappels sur l'analyse linguistique nous permet d'établir un début de structure du tableau noir du système. Nous consolidons nos choix par une comparaison du système attendu avec quelques prototypes du domaine. Nous examinons ensuite les comportements sociaux de deux agents chargés de définir l'un un modèle linguistique partiel suffisant du rédacteur et l'autre un sous-ensemble pertinent du système global. Nous découvrons alors le modèle de communication des agents et complétons notre structure de données par les marques de validité.<BR> La méthode des structures permet une quantification, incluse dans le tableau noir, de la correction des fautes d'accords.<BR> Après une approche des systèmes multi-agents, nous présentons une synthèse de l'architecture de CELINE et du fonctionnement des pilotes et de quelques agents.<BR> Un bilan rapide, précèdera en conclusion, une mise en situation du système proposé dans le cadre des industries de la langue et dans un environnement réseau du type Internet.
