This paper introduces a framework for route directions based on research results from cognitive science. Contrary to existing route planning systems this approach focuses on cognitive aspects to improve the communication of route knowledge. In order to achieve cognitively adequate communication we need to (a) organise data according to the cognitive model of the wayfinder and (b) specify this o...

MOTIVATION Biologists often wish to use their knowledge on a few experimental models of a given molecular system to identify homologs in genomic data. We developed a generic tool for this purpose. RESULTS Macromolecular System Finder (MacSyFinder) provides a flexible framework to model the properties of molecular systems (cellular machinery or pathway) including their components, evolutionary...

This paper deals with self-localization of a mobile robot on the condition that no a-priori knowledge about the environment is available. The applied method features to be accurate, robust, independent of any artificial landmarks and feasible with such a moderate computational effort that all necessary tasks can be executed in real-time on a standard PC. The perception system used is a panorama...

Navigation has always been an interdisciplinary topic of research, because mobile agents of different types are inevitably faced with similar navigational problems. Therefore, human navigation can readily be compared to navigation in other biological organisms or in artificial mobile agents like autonomous robots. One such navigational strategy, route-based navigation, in which an agent moves f...

We establish new lower bounds and impossibility results for noninteractive zero-knowledge proofs and arguments with set-up assumptions. – For the common random string model, we exhibit a lower bound for the trade-off between hardness assumptions and the length of the random string for non-interactive zero-knowledge proofs. This generalizes a previous result ruling out non-interactive zero-knowl...

Heuristic evaluation of possible route choices allows pedestrians to make decisions in a timely and efficient manner. The heuristic function used to evaluate the route and the subsequent route selection has a large impact on the egress time of the pedestrian. We implement several common heuristic functions using the PLEASE simulation model and allow these heuristics to be combined using weighte...

AIMS is a knowledge-based system for learning and teaching support within the context of distance education. It is aimed not only at enhancing learner's conceptual knowledge in a specific subject area but also at providing knowledge verification tools for the teacher. The system can be used to aid learning and teaching in different subject areas and to provide user-oriented support in searching...

This paper describes research on automating scientific and engineering computing by combining domain knowledge, mathematical theory, artificial intelligence techniques, and numerical software. We present two case studies: kinematic analysis of mechanisms and phase space analysis of dynamical systems. The case studies illustrate our general strategy of identifying an important task domain, forma...

Computational Linguistic refers to the development of computer systems that deal with human languages. In this paper, different Techniques such as Parts Speech (POS) tagger, ‘Sandhi’ Splitter, ‘Alankaar’ Finder and ‘Samaas’ were considered. After a thorough literature review, it was found fifteen techniques used for POS tagging, nine splitting, one work is done finder absolutely no are availabl...
