Caraterização dos padrões de jogo ofensivos após recuperação de posse bola a partir de desarme ou interceção: análise comparativa da equipa principal e equipa B do Sporting Club de Portugal

O jogo de futebol, e simultaneamente o seu processo ofensivo, tem sido, nos últimos anos, alvo de diversos trabalhos de investigação. Tendo como objetivo a sua análise e caracterização, o especial interesse por parte dos investigadores tem estado focado predominantemente no processo ofensivo no seu todo, desde a recuperação de posse de bola, o desenvolvimento do processo em si e a sua finalização. O presente estudo teve como principal objetivo a caraterização do processo ofensivo da equipa principal e equipa B do Sporting Clube de Portugal após recuperação de posse de bola por desarme ou interceção. Foram registadas as sequências ofensivas de 16 jogos (8 por equipa), da equipa principal e da sua equipa B, da época 2014/15, na condição de visitado, com recurso ao software Videobserver (Afra, 2013). As sequências ofensivas foram observadas e registadas a partir da recuperação de posse de bola de forma dinâmica, ou seja, através de desarme ou interceção. Para a análise estatística descritiva e sequencial foi utilizado o software SDIS GSEQ 5.1 (Bakeman & Quera, 1996). Os resultados permitiram concluir que i) as equipas observadas recuperaram a posse de bola maioritariamente no setor médio defensivo e numa relação de igualdade ou superioridade relativa; ii) as equipas observadas, desenvolvem o processo ofensivo de forma semelhante, recorrendo ao passe curto ou médio, para a frente, ou diagonal frente e rasteiro como comportamento mais vezes verificado após a recuperação de posse de bola; iii) O método de jogo ofensivo mais utilizado pelas equipas observadas é o ataque rápido. A equipa principal do SCP, ao contrário da equipa B, não é influenciada pela forma como o adversário reage à perda de posse de bola para optar pelo seu método de jogo ofensivo; iv) no caso da equipa principal, o método de jogo ofensivo que potencia mais situações de finalização com sucesso é o ataque rápido, enquanto na equipa B é o contra-ataque; v) ambas as equipas optam pelo método de jogo ofensivo contra-ataque, quando a recuperação de posse de bola acontece no setor defensivo e setor médio defensivo, sendo substituído pelo ataque rápido nos setores mais adiantados.

'Danger Theory: The Link between AIS and IDS?'

Abstract We present ideas about creating a next generation Intrusion Detection System (IDS) based on the latest immunological theories. The central challenge with computer security is determining the difference between normal and potentially harmful activity. For half a century, developers have protected their systems by coding rules that identify and block specific events. However, the nature of current and future threats in conjunction with ever larger IT systems urgently requires the development of automated and adaptive defensive tools. A promising solution is emerging in the form of Artificial Immune Systems (AIS): The Human Immune System (HIS) can detect and defend against harmful and previously unseen invaders, so can we not build a similar Intrusion Detection System (IDS) for our computers? Presumably, those systems would then have the same beneficial properties as HIS like error tolerance, adaptation and self-monitoring. Current AIS have been successful on test systems, but the algorithms rely on self-nonself discrimination, as stipulated in classical immunology. However, immunologist are increasingly finding fault with traditional self-nonself thinking and a new 'Danger Theory' (DT) is emerging. This new theory suggests that the immune system reacts to threats based on the correlation of various (danger) signals and it provides a method of 'grounding' the immune response, i.e. linking it directly to the attacker. Little is currently understood of the precise nature and correlation of these signals and the theory is a topic of hot debate. It is the aim of this research to investigate this correlation and to translate the DT into the realms of computer security, thereby creating AIS that are no longer limited by self-nonself discrimination. It should be noted that we do not intend to defend this controversial theory per se, although as a deliverable this project will add to the body of knowledge in this area. Rather we are interested in its merits for scaling up AIS applications by overcoming self-nonself discrimination problems.

Odpowiedzialność lekarza, podmiotu leczniczego i ubezpieczyciela za nieudane transplantacje

Transplantacje komórek, tkanek i narządów należą do najbardziej kontrowersyjnych procedur medycznych, gdyż dotykają także kwestii etycznych i światopoglądowych. W ostatnich latach niewątpliwie obserwujemy rozwój transplantologii dzięki postępowi w naukach medycznych oraz zmianach w świadomości społeczeństwa. Transplantologia pozostaje jedną z bardziej ryzykownych gałęzi medycyny, ponieważ postępowanie zgodnie z zasadami sztuki lekarskiej nie jest gwarancją powodzenia przeszczepu. Artykuł przybliża problematykę nieudanych transplantacji – zarówno ze względu na zaniedbania lekarza czy placówki medycznej, jak i ze względu na reakcję obronną organizmu. W drugiej części artykułu zostały opisane zasady odpowiedzialności cywilnej lekarzy i innych pracowników podmiotów leczniczych za szkody wyrządzone pacjentom oraz wskazano czym różni się odpowiedzialność sprawcy szkody od odpowiedzialności ubezpieczyciela. Kolejna część artykułu dotyczy specyfiki odpowiedzialności ubezpieczyciela za nieudane transplantacje w oparciu o rozporządzenie Ministra Finansów w sprawie obowiązkowego ubezpieczenia odpowiedzialności cywilnej podmiotów wykonujących działalność leczniczą.

Wind turbine indirect ice detection and operational analysis

Wind energy is one of the most promising and fast growing sector of energy production. Wind is ecologically friendly and relatively cheap energy resource available for development in practically all corners of the world (where only the wind blows). Today wind power gained broad development in the Scandinavian countries. Three important challenges concerning sustainable development, i.e. energy security, climate change and energy access make a compelling case for large-scale utilization of wind energy. In Finland, according to the climate and energy strategy, accepted in 2008, the total consumption of electricity generated by means of wind farms by 2020, should reach 6 - 7% of total consumption in the country [1]. The main challenges associated with wind energy production are harsh operational conditions that often accompany the turbine operation in the climatic conditions of the north and poor accessibility for maintenance and service. One of the major problems that require a solution is the icing of turbine structures. Icing reduces the performance of wind turbines, which in the conditions of a long cold period, can significantly affect the reliability of power supply. In order to predict and control power performance, the process of ice accretion has to be carefully tracked. There are two ways to detect icing – directly or indirectly. The first way applies to the special ice detection instruments. The second one is using indirect characteristics of turbine performance. One of such indirect methods for ice detection and power loss estimation has been proposed and used in this paper. The results were compared to the results directly gained from the ice sensors. The data used was measured in Muukko wind farm, southeast Finland during a project 'Wind power in cold climate and complex terrain'. The project was carried out in 9/2013 - 8/2015 with the partners Lappeenranta university of technology, Alstom renovables España S.L., TuuliMuukko, and TuuliSaimaa.

The Origins and Legacy of a Currency Board in Argentina

This is a qualitative case study of the adoption of a currency board in Argentina in 1991. It presents a discursive analysis and intellectual history of four overlaying and mutually influencing stories of Convertibility’s adoption. It is (1) the story of how Menem aligned himself to the Washington Consensus as a means to win a Presidential election. This ideological alignment influences and is influenced by a (2) reconstitution of the Peronist Party’s historically entrenched identity. This in turn re-fashion the whole system of interest articulation and relative power of interest groups in Argentina. The adoption of a currency board also marks the pace of (3) the entrenchment neoliberal interests across a domestic network of neoliberal think-tanks, technocrats, politicians, and “technopoles” articulating neoliberal interests outside of the Washington Consensus, within an International Neoliberal Network. Argentina’s adoption of a currency board falls in line with the Corner Solutions, a neoliberal doctrine promoted to influence developing countries to adopt two forms of exchange rate regimes that allow for less government involvement, including a currency board. Argentina starts as a test country and then becomes (4) an ideological stepping stone to help promote the creation of currency boards across more “developing” countries. These stories are not sequential but concurrent, and they help advance an alternative critique of neoliberalism that focuses on specifics to induce case-specific lessons versus a theory claiming to provide any universal truth.

L'Espagne en Tunisie: projet de sauvegarde et de mise en valeur du Fort de "La Karraka" à La Goulette

La Tunisie a été toujours considérée comme terre de rencontre de plusieurs civilisations, compte tenu de son emplacement stratégique et de son histoire très enracinée. En effet, depuis l’Antiquité ce pays a connu l’installation ou le passage de plusieurs ethnies, qui ont profondément marqué les trois milles ans de son Histoire en dépit de la période ou de la nature de l’occupation et dont les traces constituent aujourd’hui le patrimoine de ce pays. Cet héritage matériel et immatériel semble être parmi les plus riche de la Méditerranée, pour ce, plusieurs villes historiques et sites archéologiques ont été inscrites sur la liste du patrimoine mondial depuis plusieurs décennies. Plusieurs composantes de ce patrimoine furent l’objet de certains projets d’inventaire et d’études, de sauvegarde et de valorisation, tels les sites archéologiques libyques, puniques ou romains, ou même les villes arabo-islamiques. Plusieurs musées, circuits culturels et Parcs archéologiques furent crées. D’autres projets de mise en valeur sont en cours, tels ceux des villes et des villages andalous ou ceux des villages montagneux et des Ksours du sud tunisien… alors que le patrimoine architectural espagnol en Tunisie n’a pas eu jusqu’à présent l’intérêt qu’il mérite malgré son importance et son authenticité et doit être aujourd’hui sauvegardé, mis en valeur et intégré dans la vie patrimoniale et le les circuits culturels et touristiques de la région. Le présent travail réalisé dans le cadre du mémoire de master traite la problématique de la sauvegarde et la mise en valeur d’un monument de type défensif comme cas d’étude. Il s’agit de la Karraka, forteresse bâtie à la ville de la Goulette réagissant à son milieu comme un organisme vivant avec toutes ses variations et déformations de volumes et surtout dans cette typologie dite défensive en se concentrant sur le rôle magistral de la Karraka. L’objectif final de ce projet est de mettre en valeur la validité d’une perception dynamique du patrimoine à travers l’étude de ce monument défensif dans son contexte historique et géographique en particulier et l’essai sur l’histoire de la Goulette; ABSTRACT: Tunisia has always been considered as the meeting earth of several civilizations regarding its strategic position on its deep rooted history. Since the antiquity this country was known the installation or the passage of several ethnics which deeply marqued the three Milles years of its history despite the difficult period of the French occupation its traces are still the country's heritage. This tangible and intangible heritage seems to be among the richest in the Mediterranean in several historic towns and archaeological sites have been listed on the World Heritageas well List for several decades. Many components of this heritage were the object of some inventory projects and studies, Backup and recovery, such the archaeological sites Libyan, Punic, Roman, and even the Arab Islamic cities. Many museums created cultural tours and archaeological parks, we have also other development projects are on the way, such as the Andalusian villages and those of mountain villages and southern Tunisia Ksours….. While the heritage of Spanish architecture in Tunisia has no interest despite its importance and authenticity it must be saved, and it must integrated into the life and heritage and the cultural tours of the region. This work carried out under the master thesis deals with the problem of preservation and development of a defensive type of monument as a case study “ Karraka” This fortress was built in the city of « La Goulette » reacting to his environment as a living organism with all its variations and volume deformations and especially in this so-called defensive typology by focusing on the role of magisterial Karraka. The final objective of this project is to highlight the validity of a dynamic perception of heritage through the study of the defensive monument in its historical and geographical context in particular and the article on the history of « La Goulette ».

Light losses in hollow, prismatic light guides related to prim defects: a transmittance model

Hollow, cylindrical, prismatic light guides (CPLGs) are optical components that, using total internal reflection (TIR), are able to transmit high-diameter light beams in daylight and artificial lighting applications without relevant losses. It is necessary to study the prism defects of their surfaces to quantify the behavior of these optical components. In this Letter, we analyze a CPLG made of a transparent dielectric material. Scanning electron microscopy (SEM) and the topographic optical profilometry by absorption in fluids (TOPAF) imaging technique are conducted to determine if there are defects in the corners of the prisms. A model for light guide transmittance that is dependent on prism defects is proposed. Finally, a simulation and an experimental study are carried out to check the validity of the proposed model.

Para além do trabalho realizado ao longo de toda a época na área da análise de jogo, este documento contêm ainda dois estudos realizados com a equipa sénior do Estoril-Praia, Futebol SAD: (1) estudo de grupo que aborda o nível de coesão da equipa e (2) um estudo de investigação que procura avaliar os comportamentos da equipa quando está organizada ou em recuperação defensiva.

Práticas de observação e análise de jogo

A Observação e Análise é uma área em crescimento nos últimos anos. Hoje em dia, a presença de um departamento de Observação e Análise nos clubes é visto como essencial uma vez que, no futebol de alto rendimento, os jogos estão cada vez mais equilibrados, sendo decididos muitas vezes por pormenores. Neste sentido existe uma maior necessidade de inclusão de equipas técnicas multidisciplinares com o objetivo de melhorar o rendimento da equipa e alcançar o sucesso. As equipas de topo devem controlar ao máximo todos os fatores que influenciam o rendimento dos jogadores e, a Observação e Análise de jogo é um deles. Este relatório surge no âmbito do estágio realizado no Sport Lisboa e Benfica, mais concretamente no departamento de Observação e Análise do Benfica LAB, na época desportiva 2014/2015. Encontra-se dividido em três partes fundamentais. A Área 1 (Prática Profissional) foca-se na exposição detalhada das formações específicas que nos foram proporcionadas bem como todas as tarefas operacionais e complementares realizadas ao longo do estágio, subjacentes a um departamento de Observação e Análise. A segunda parte é referente à Área 2 (Inovação e Investigação) – desenvolvimento de um estudo de investigação que carateriza as ações técnico-táticas individuais do Sport Lisboa e Benfica por posição (posto específico) com o objetivo de averiguar diferenças significativas entre épocas desportivas. Concluiu-se a existência de diferenças significativas. As posições que apresentaram o maior número de diferenças entre épocas desportivas foram as posições médio defensivo e primeiro avançado. Finalmente, a última parte deste relatório centra-se na Área 3 (Relação com a Comunidade). São explicados detalhadamente todos os procedimentos da organização e dinamização de um evento vocacionado para a formação de agentes que intervém direta ou indiretamente na Observação e Análise de Jogo.
