Gestão de informação académica com base na Web: um sistema de apoio a programas de pós-graduação

Esta dissertação descreve o processo de desenvolvimento de um sistema de informação para a gestão da informação académica de programas de pósgraduação - Sistema WebMaster - que tem como objectivo tornar aquela informação acessível aos utilizadores através da World Wide Web (WWW). Começa-se por apresentar alguns conceitos que se julgam relevantes para a compreensão da problemática dos sistemas de informação em toda a sua abrangência numa determinada organização, particularizando alguns conceitos para o caso das universidades. De seguida reflecte-se sobre os sistemas de informação com base na Web, confrontando-se os conceitos de Web Site (tradicional) e aplicação Web, a nível de arquitectura tecnológica, principais vantagens e desvantagens, fazendo-se, ainda, uma breve referência às principais tecnologias para a construção de soluções com geração dinâmica de conteúdos. Por último representa-se o sistema WebMaster ao longo das suas diferentes etapas de desenvolvimento, desde a análise de requisitos, projecto do sistema, até à fase da implementação. A fase análise de requisitos foi levada a cabo através de um inquérito realizado aos potenciais utilizadores no sentido de identificar as suas necessidades de informação. Com base nos resultados desta fase apresenta-se o projecto do sistema numa perspectiva conceptual, navegacional e de interface de utilizador, fazendo uso da metodologia OOHDM - Object-Oriented Hypermedia Design Method. Finalmente, passa-se à fase da implementação que, com base nas etapas anteriores e nas tecnologias seleccionadas na fase do planeamento, proporciona um espaço interactivo e de troca de informação a todos os interessados da comunidade académica envolvidos em cursos de pós-graduação.

GIS on tourism planning: preventing the impacts caused by the developing tourism activity in a specific site

The environment is one of the greatest concerns of humankind. Nowadays, the activities which improve or destroy it must be assessed and controlled by efficient means which should permit the control of environmental impact caused by the development of these activities. This document presents an information system implementation, as a Decision Support system, allowing the Decision Maker to evaluate, foresee and control the future environmental impact of Tourism through consultation, the management and the presentation of decision schemes based on defined measures of a regional tourism planning.

A computer vision based web application for tracking soccer players

Soccer is a sport where everyone that is involved with it make all the efforts aiming for excellence. Not only the players need to show their skills on the pitch but also the coach, and the remaining staff, need to have their own tools so that they can perform at higher levels. Footdata is a project to build a new web application product for soccer (football), which integrates two fundamental components of this sport's world: the social and the professional. While the former is an enhanced social platform for soccer professionals and fans, the later can be considered as a Soccer Resource Planning, featuring a system for acquisition and processing information to meet all the soccer management needs. In this paper we focus only in a specific module of the professional component. We will describe the section of the web application that allows to analyse movements and tactics of the players using images directly taken from the pitch or from videos, we will show that it is possible to draw players and ball movements in a web application and detect if those movements occur during a game. © 2014 Springer International Publishing.

Nichtmonetäres Controlling der Lehrleistungen an der Fachhochschule Hannover

In Niedersachsen setzt das Ministerium für Wissenschaft und Kultur seit 2007 ein Hochschulkennzahlensystem ein, um einen Teil des Grundhaushalts wettbewerblich an die Hochschulen zu verteilen. Über die Mittelvergabe hinaus ist ein Monitoringsystem integriert, mit dem die Entwicklung der Hochschulen beurteilt werden kann. Zur differenzierten Beurteilung werden monetäre und nichtmonetäre Hochschuldaten zu Kennzahlen verdichtet. Die Kennzahlen befinden sich jedoch auf einer zu hohen Aggregationsebene für ein hochschulinternes Controlling an der Fachhochschule Hannover. Daher dienen Berichtssysteme mit Standardberichten der Information über hochschulweite Prozesse und Ressourcen, um im zunehmenden Wettbewerb der Fachhochschulen fundierte Entscheidungen treffen zu können. Beispielhaft werden Standardberichte zu erbrachten Lehrleistungen als erste Komponente des nichtmonetären Controllings in einem Berichtssystem konzipiert. Methodisch basiert die Konzeption auf einer Informationsbedarfsanalyse mit induktiven und deduktiven Verfahren. Das Vorgehen lässt sich grundsätzlich auf weitere nichtmonetäre Leistungen (z. B. der Forschung) übertragen und in die konzipierte Struktur integrieren.

Erstellung wiederverwendbarer RDF-Geodaten mit Google Refine

Das Forschungsinformationssystem VIVO bietet als Linked-Data-basiertes System die Möglichkeit, Daten aus anderen Quellen wiederzuverwenden. In der Praxis kann man dabei auf Konvertierungsprobleme stoßen. Oft liegen Daten nur in tabellarischem Format vor, z.B. als CSV-Datei. Zur Konvertierung dieser Daten existieren verschiedene Werkzeuge, viele dieser Werkzeuge erfordern jedoch entweder spezielle technische Umgebungen (oft Linux-Systeme) oder sie sind in der Bedienung sehr anspruchsvoll. Im Artikel wird ein Workflow für die Konvertierung von Daten aus GeoNames für VIVO mit Google Refine beschrieben.

Investigating and Predicting Atmospheric Concentrations of Allergenic Fungal Spores (Alternaria, Cladosporium, Didymella and Ganoderma)

Air quality is an increasing concern of the European Union, local authorities, scientists and most of all inhabitants that become more aware of the quality of the surrounding environment. Bioaerosols may be consisted of various elements, and the most important are pollen grains, fungal spores, bacteria, viruses. More than 100 genera of fungal spores have been identified as potential allergens that cause immunological response in susceptible individuals. Alternaria and Cladosporium have been recognised as the most important fungal species responsible for respiratory tract diseases, such as asthma, eczema, rhinitis and chronic sinusitis. While a lot of attention has been given to these fungal species, a limited number of studies can be found on Didymella and Ganoderma, although their allergenic properties were proved clinically. Monitoring of allergenic fungal spore concentration in the air is therefore very important, and in particular at densely populated areas like Worcester, UK. In this thesis a five year spore data set was presented, which was collected using a 7-day volumetric spore trap, analysed with the aid of light microscopy, statistical tests and geographic information system techniques. Although Kruskal-Wallis test detected statistically significant differences between annual concentrations of all examined fungal spore types, specific patterns in their distribution were also found. Alternaria spores were present in the air between mid-May/mid-June until September-October with peak occurring in August. Cladosporium sporulated between mid-May and October, with maximum concentration recorded in July. Didymella spores were seen from June/July up to September, while peaks were found in August. Ganoderma produced spores for 6 months (May-October), and maximum concentration could be found in September. With respect to diurnal fluctuations, Alternaria peaked between 22:00h and 23:00h, Cladosporium 13:00-15:00h, Didymella 04:00-05:00h and 22:00h-23:00h and Ganoderma from 03:00h to 06:00h. Spatial analysis showed that sources of all fungal species were located in England, and there was no evidence for a long distance transport from the continent. The maximum concentration of spores was found several hours delayed in comparison to the approximate time of the spore release from the crops. This was in agreement with diurnal profiles of the spore concentration recorded in Worcester, UK. Spores of Alternaria, Didymella and Ganoderma revealed a regional origin, in contrast to Cladosporium, which sources were situated locally. Hence, the weather conditions registered locally did not exhibit strong statistically significant correlations with fungal spore concentrations. This has had also an impact on the performance of the forecasting models. The best model was obtained for Cladosporium with 66% of the accuracy.

Automatic deployment of interoperable legacy code services

The Grid Execution Management for Legacy Code Architecture (GEMLCA) enables exposing legacy applications as Grid services without re-engineering the code, or even requiring access to the source files. The integration of current GT3 and GT4 based GEMLCA implementations with the P-GRADE Grid portal allows the creation, execution and visualisation of complex Grid workflows composed of legacy and nonlegacy components. However, the deployment of legacy codes and mapping their execution to Grid resources is currently done manually. This paper outlines how GEMLCA can be extended with automatic service deployment, brokering, and information system support. A conceptual architecture for an Automatic Deployment Service (ADS) and for an x-Service Interoperability Layer (XSILA) are introduced explaining how these mechanisms support desired features in future releases of GEMLCA.
