Repository Based Software Cost Estimation (2007)
Andreas Henrich, Praktische Informatik
Abstract. One important problem with software development projects is to get an early and nevertheless accurate estimation of the software development costs. In the literature various methods have...
Abstract A distance-scan algorithm for spatial access structures (2007)
Andreas Henrich, Praktische Informatik
In geographic information systems it is often useful to select an object located closest to a given point or to scan the objects with respect to their distance to a given point in ascending order. An...
Abstract Error Propagation in Distributed Databases (2007)
O. Haase, A. Henrich, Praktische Informatik
An interesting research area for distributed database systems is inaccessibility. Even if part of the database is inaccessible, a query should be evaluated reasonably. This means, that appropriate...

The management of moving objects has been intensively studied in recent years. A wide and increasing range of database applications has to deal with spatial objects whose position changes...
M.: A pragmatic approach to pre-testing Prolog programs (2004)
Christoph Beierle, Manfred Widera, Praktische Informatik
Abstract. We present an overview on the AT(x) approach which is capable of automatically analyzing programs with respect to given tests and a reference solution. In the context of small homework...
Modelling conditional knowledge discovery and belief revision by Abstract State Machines (2003)
Christoph Beierle, Gabriele Kern-isberner, Praktische Informatik, Viii Wissensbasierte Systeme
Abstract. We develop a high-level ASM specification for the Condor system that provides powerful methods and tools for managing knowledge represented by conditionals. Thereby, we are able to...
Analysis of a location service for position-based routing in mobile ad hoc networks (2002)
Michael Käsemann, Hannes Hartenstein, Holger Füßler, Martin Mauve, Praktische Informatik
Abstract: Position-based routing in a mobile ad hoc network requires geographic addresses. Thus, a node that wants to send a packet to some target node has to know the target’s (approximate)...
