Education and training of the workforce have become an important competitive factor for companies because of the rapid technological changes in the economy and the corresponding ever shorter innovation cycles. Traditional training methods, however, are limited in terms of meeting the resulting demand for education and training in a company, which continues to grow and become faster all the time. Therefore, the use of technology-based training programs (that is, courseware) is increasing because courseware enables self-organized and self-paced learning and, through integration into daily work routines, allows optimal transfer of knowledge and skills, resulting in high learning outcome. To achieve these prospects, high-quality courseware is required, with quality being defined as supporting learners optimally in achieving their learning goals. Developing high-quality courseware, however, usually requires more effort and takes longer than developing other programs, which limits the availability of this courseware in time and with the required quality.
This dissertation therefore deals with the research question of how courseware has to be developed in order to produce high-quality courseware with less development effort and shorter project duration. In addition to its high quality, this courseware should be optimally aligned to the characteristics and learning goals of the learners as well as to the planned usage scenarios for the knowledge and skills being trained. The IntView Method for the systematic and efficient development of high-quality courseware was defined to answer the research question of this dissertation. It aims at increasing the probability of producing courseware in time without exceeding project schedules and budgets while developing a high-quality product optimally focused on the target groups and usage scenarios.
The IntView Methods integrates those execution variants of all activities and activity steps required to develop high-quality courseware, which were identified in a detailed analysis of existing courseware development approaches as well as production approaches from related fields, such as multimedia, web, or software engineering, into a systematic process that in their interaction constitute the most efficient way to develop courseware. The main part of the proposed method is therefore a systematic process for engineering courseware that encompasses all courseware lifecycle phases and integrates the activities and methods of all disciplines involved in courseware engineering, including a lifecycle encompassing quality assurance, into a consolidated process. This process is defined as a lifecycle model as well as a derived process model in the form of a dependency model in order to optimally support courseware project teams in coordinating and synchronizing their project work. In addition to the models, comprehensive, ready-to-apply enactment support materials are provided, consisting of work sheets and document templates that include detailed activity descriptions and examples.
The evaluation of the IntView Method proved that the method together with the enactment support materials enables efficient as well as effective courseware development. The projects and case studies conducted in the context of this evaluation demonstrate that, on the one hand, the method is easily adaptable to the production of different kinds of courseware or to different project contexts, and, on the other hand, that it can be used efficiently and effectively.

Generalized methods for automated theorem proving can be used to compute formula transformations such as projection elimination and knowledge compilation. We present a framework based on clausal tableaux suited for such tasks. These tableaux are characterized independently of particular construction methods, but important features of empirically successful methods are taken into account, especially dependency directed backjumping and branch local operation. As an instance of that framework an adaption of DPLL is described. We show that knowledge compilation methods can be essentially improved by weaving projection elimination partially into the compilation phase.

Data visualization is an effective way to explore data. It helps people to get a valuable insight of the data by placing it in a visual context. However, choosing a good chart without prior knowledge in the area is not a trivial job. Users have to manually explore all possible visualizations and decide upon ones that reflect relevant and desired trend in the data, are insightful and easy to decode, have a clear focus and appealing appearance. To address these challenges we developed a Tool for Automatic Generation of Good viSualizations using Scoring (TAG²S²). The approach tackles the problem of identifying an appropriate metric for judging visualizations as good or bad. It consists of two modules: visualization detection: given a data-set it creates a list of combination of data attributes for scoring and visualization ranking: scores each chart and decides which ones are good or bad. For the later, an utility metric of ten criteria was developed and each visualization detected in the first module is evaluated on these criteria. Only those visualizations that received enough scores are then presented to the user. Additionally to these data parameters, the tool considers user perception regarding the choice of visual encoding when selecting a visualization. To evaluate the utility of the metric and the importance of each criteria, test cases were developed, executed and the results presented.
Taktstraße
(2008)
Eine Taktstraße ermöglicht eine automatisierte Verarbeitung eines Werkstückes mit Hilfe von Förderbändern, Lichtschranken, Schiebern und Bearbeitungsstationen. Für eine vorgegebene Taktstraße wird eine Ansteuerung entwickelt. Dazu wird der Mikrocontroller ATMega16 von Atmel eingesetzt. Ein externer Controller sendet über den TWI-Bus Steuerbefehle an den mit der Taktstraße verbundenen Controller. Um die Taktstraße bedienbar zu machen, wird eine geeignete Platine entworfen sowie eine LCD-Bibliothek als Ausgabe- und Informationsmedium. Die Arbeit umfasst alle für ein Projekt im Rahmen eines Informatikstudiums benötigten Entwicklungsstadien von der Projektplanung über die Aneignung von spezifischem Grundlagenwissen, die Hard- und Softwareentwicklung bis hin zu ausführlichen Entwicklungs- und Testphasen.
Taxonomy and Systematics of Spiny-Backed Treefrogs, Genus Osteocephalus (Amphibia: Anura: Hylidae)
(2015)
The pan-Amazonian treefrog genus Ostecephalus is poorly understood both on a taxonomic and phylogenetic level. The status of several frogs already or not yet referred to the genus is unclear and the relationships among the genus and with respect to related genera is not understood. In this work O. cabrerai (Cochran and Goin, 1970) from Colombia and Peru is redescribed and O. festae (Peracca, 1904) from the foothills of the Andes in Ecuador is revalidated. Hyla inframaculata Boulenger, 1882, from the lower Amazon in Brazil, is reallocated to Osteocephalus and O. elkejungingerae (Henle, 1981) from the Andean foothills in Peru is shown to be a synonym of Hyla mimetica (Melin, 1941), the valid name being O. mimeticus. Hyla vilarsi Melin, 1941 is considered a valid species in the genus Osteocephalus and revalidated from the synonymies of several other frogs. Three new species, O. castaneicola from northern Bolivia and southern Peru, O. duellmani from a sub-Andean mountain range in southern Ecuador, and O. camufatus from central Amazonian Brazil, are described. A phylogenetic analysis based on up to nine mitochondrial genes and one nuclear one reveals the paraphyly of the genus as previously understood with respect to the genus Tepuihyla. A new taxonomy is proposed, securing the monophyly of Osteocephalus and Tepuihyla by rearranging and redefining the content of both genera. A new genus, Dryaderces, is erected for the sister group of Osteocephalus. The colouration of newly metamorphosed individuals is proposed as a morphological synapomorphy for Osteocephalus. Five monophyletic species groups within Osteocephalus are recognized, three species of Osteocephalus (O. germani, O.rnphasmatus, O. vilmae) and three species of Tepuihyla (T. celsae, T. galani, T. talbergae) synonymized and three species (Hyla helenae to Osteocephalus, O.rnexophthalmus to Tepuihyla and O. pearsoni to Dryaderces gen. n.) reallocated. Furthermore, nine putative new species are flagged (an increase to 138% of the current diversity), an indication that species numbers are largely underestimated, with most hidden diversity centred on widespread and polymorphic nominal species. The evolutionary origin of breeding strategies within Osteocephalus is discussed in the light of this new phylogeny and a novel type of amplexus (gular amplexus) is described.
Web-programming is a huge field of different technologies and concepts. Each technology implements a web-application requirement like content generation or client-server communication. Different technologies within one application are organized by concepts, for example architectural patterns. The thesis describes an approach for creating a taxonomy about these web-programming components using the free encyclopaedia Wikipedia. Our 101companies project uses implementations to identify and classify the different technology sets and concepts behind a web-application framework. These classifications can be used to create taxonomies and ontologies within the project. The thesis also describes, how we priorize useful web-application frameworks with the help of Wikipedia. Finally, the created implementations concerning web-programming are documented.
