In zehn voralpinen Kleinseen wurde eine neuartige Methode der ökologischen Gewässerbewertung etabliert. Neben der Erfassung der biologischen Parameter an Hand des Diatomeenindexes (Kurzzeitindikator) und des Makrophytenindexes (Langzeitindikator) wurde mit Hilfe eines Geographischen Informationssyte...

The research group Cooperative Autonomous Systems of the Institute for Autonomous intelligent systems (AiS.CAS) of the GMD - German national research center for information technology, in cooperation with the institute for distributed systems of the University of Magdeburg, develops a common platfor...
Training a Personal Alert System for Research Information Recommendation
Information Systems, and in particular Current Research Information Systems (CRISs), are usually quite difficult to query when looking for specific information, due to the huge amounts of data they contain. To solve this problem, we propose to use a personal search agent that uses fuzzy and rough se...
Based on a sample of 946 German insurance intermediaries, the factors that affect the quality of the information services provided by them are studied using OLS-estimations. Applying a search theoretical approach, we analyze the impact of supply and demand side variables on service quality. Besides,...
Some Aspects of Gas Turbine Fuel Preparation and Turbomachinery Response to LCV Fuels
This thesis gives some background information on environmental issues as the scientific community at large currently sees it. It tries to relate the plethora of current combustion technologies which may be used in gas turbines to those issues. Some basic principles on combustion design are given. Di...
Seit vielen Jahren ist absehbar, dass die Kapazitäten des deutschen Straßennetzes nicht ausreichen, um das weiterhin ansteigende Verkehrsaufkommen bewältigen zu können. Eine bessere Nutzung der vorhandenen Infrastruktur durch den Einsatz von Verkehrsinformations- und -leitsystemen ermöglicht jedoch ...

This contribution represents a supplement to the article "On the Relevance of Design Knowledge for Design-Oriented Business and Information Systems Engineering – Conceptual Foundations, Application Example, and Implications" in the special issue on Science of Business and Information Systems Enginee...
On synthesis in the later phases of the mechanical engineering design process
Only 15% to 30% of product development projects require the development of new product concepts. This means that the majority of design projects are carried out within the embodiment design and detail design phases. However, the majority of the research studies on the mechanical engineering design p...
The damage caused by the dramatic worldwide increase in ‘natural’ disasters is staggering, with the poor in developing countries being most at risk. Disasters make their already precarious living conditions worse, creating a vicious circle of poverty from which they find it hard to escape. To achiev...
This study examined whether individuals with a wide range of first-language vowel systems (Spanish, French, German, and Norwegian) differ fundamentally in the cues that they use when they learn the English vowel system (e.g., formant movement and duration). All subjects: (1) identified natural Engli...
Le développement de la morphologie verbale de personne-nombre chez différents types d’apprenants
La morphologie verbale de personne-nombre se développe lentement chez les apprenants adultes (suédophones) de français L2. Ce développement, chez eux, ne semble pas relié au développement syntaxique, mais possiblement à des facteurs de fréquence de ces formes dans l’input. On ne peut pas non plus co...
Knowledge-Based Meta-Data Validation: Analyzing a Web-Based Information System
Web-based information systems play an important role in today's practice of data-analysis and reporting in the field of environmental protection. While these systems solved some technical problems concerning the integration and visualization of information they show some problems even harder to hand...
Investeringar i kommunal infrastruktur: Förutsättningar för en målfokuserad investeringsverksamhet
Capital assets in local infrastructure constitute an overbearing concern for society, with the generation of benefits for the population being its prime purpose. Nevertheless, the conditions for the capital investment activities within local governments are diffuse. Which different kinds of investme...
Integrating structured and unstructured data in a business-intelligence-system
The recent liberalization of the German energy market has forced the energy industry to develop and install new information systems to support agents on the energy trading floors in their analytical tasks. Besides classical approaches of building a data warehouse giving insight into the time series ...
Influences, effects and changes from interventions by eco-labelling schemes - What a Swan can do?
Eco-labelling is a voluntary and informative policy instrument aiming at stimulating environmentally beneficial product development through using the market forces. The Nordic Swan eco-labelling scheme has been in operation since 1989. The research presented in this thesis concentrates on the kinds ...
Fully integrated business software and its impact on German universities
German universities are undergoing major structural changes since the mid 90ies. In this process fully integrated business software has become one of the main tools to improve the management capabilities of the higher education sector. However, the transformation process has turned out to be stony a...
Executive information systems and German asset management companies
The utilization of Information Technology in the present business environment is, surely one of the most important success factors. However, conventional Information Systems often do not sufficiently cover the extremely complex information needs of Executives. This essay deals with this problem. It ...
This study examines the question on why firms outsource particular information systems (IS) functions to varying degrees. It is the first to simultaneously examine three theoretical perspectives that represent different rationales for and against IS outsourcing. The first of these perspectives is ne...

Chemical footprints as cues to foraging bumblebees and pollination ecologists
Many plant species are known to emit species-specific floral scents to attract or guide pollinators, thereby ensuring cross pollination. In combination with visual traits, pollinators use these cues to localize floral resources and to specialize on the most rewarding plant species. To complicate mat...
Bias, Misinformation and the Paradox of Neutrality.
What is normally described as bias? A possible definition comprises attempts to distort or mislead to achieve a certain perspective, i.e. subjective descriptions intended to mislead. If designers were able to exclude bias from informing systems, then this would maximize their effectiveness. This imp...
We used a dictionary-based approach, and performed tests in the bilingual track with three language pairs, i.e., Swedish - English (Swe-Eng), Finnish - English (Fin-Eng), and German - English (Ger-Eng). All the source languages are compound languages, i.e., languages rich in compound words. A comp...
