A grand challenge for power grid management lies in how to plan and operate with increasing penetration of distributed energy resources (DERs), such as solar photovoltaics and electric vehicles, which disturb the power grid stability. Existing approaches are unable to verify if a point is on a loadability boundary or characterize all loadability boundary points exactly. This inability leads to ...

Innerhalb der Gesellschaft für Informatik e.V. (GI) hat sich eine Gruppe auf die Suche gemacht nach den „Grand Challenges“ der Informatik. Eine "Grand Challenge" so der Versuch einer Definition stellt ein grundsätzliches Problem in der Informatik oder für die Informatik dar, dessen Lösung mit InformatikHilfsmitteln einen deutlich spürbaren Fortschritt in ökonomischer, sozialer oder gesellschaft...

Information is ubiquitous, and we are flooded with more than we can process. Somehow, we must rely less on visual processing, point-and-click navigation, and manual decision making and more on computer sifting and organization of information and automated negotiation and decision making. A resolution of these problems requires software with semantic understanding—a grand challenge of our time. ...

Due to the technical developments in electronics the amount of digital content is continuously increasing. In order to make digital content respectively multimedia content available to potentially large and geographically distributed consumer populations, Content Distribution Networks (CDNs) are used. The main task of current CDNs is the efficient delivery and increased availability of content ...

Virtual Reality is an exciting new area of human-computer interaction. Its use depends critically on having extremely low response times of the virtual environment to user interaction. The problem of reducing the lag between the user’s head position or orientation changing and the updating of the displayed view has been described as one of the grand challenges of computing. The techniques descr...

This paper reviews some common knowledge about establishing correctness of programs and the current status of program specification and verification. While doing so, it identifies several challenges related to the grand challenge of building a verifying compiler. The paper argues that invariants are central to establishing correctness of programs and that thus, a major part of an automatic prog...

Modelling and simulation of multiscale systems constitutes a grand challenge in computational science, and is widely applied in fields ranging from the physical sciences and engineering to the life sciences and the socio-economic domain. To adequately simulate numerous intertwined processes characterized by different spatial and temporal scales (often spanning many orders of magnitude), sophist...

Informatik ist mittlerweile ubiquitär, auch oder vielleicht gerade in der Landwirtschaft. Das Interesse an der Agrarinformatik stagniert dagegen eher, ist vielleicht sogar rückläufig. Indizien hierfür sind die Mitgliederzahlen der GIL aber auch Streichungen von Professuren mit dem Schwerpunkt Agrarinformatik an Universitäten, wie zuletzt im Jahre 2012 in Kiel. Es scheint somit eine Diskrepanz z...

Overview: Science is arguably the pinnacle of human intellectual achievement, yet the scientific discovery process itself remains an art. Human intuition and experience are still the driving forces of the high-level discovery process: we determine which hypotheses and theories to entertain, which experiments to conduct, how data should be interpreted, when hypotheses should be abandoned, and so...
