The aim of this paper is to present recent progress in calibrating ten microscopic traffic flow models. The models have been tested using data collected via DGPS-equipped cars (Differential Global Positioning System) on a test track in Japan. To calibrate the models, the data of a leading car are fed into the model under consideration and the model is used(More)
When working on large-scale traffic observation projects very often simulations and therefore, models of the behaviour of the molecular simulation elements (the car-driver-units) are needed. Most of the models for traffic simulations are based on approximations of statistical real-world data. While fast in computation, they sometimes fail to show real-world(More)
Agriculture is a knowledge-intensive business. This paper is going to expand the discussions on ICT adoption to the field of knowledge management. The question is not any more if a computer with Internet access is available, but rather for what knowledge processes it is used for. For this, the results of empirical studies over the last four years in Germany(More)
This paper describes the TextLearner prototype, a knowledge-acquisition program that represents the culmination of the DARPA-IPTO-sponsored Reading Learning Comprehension seedling program, an effort to determine the feasibility of autonomous knowledge acquisition through the analysis of text. Built atop the Cyc Knowledge Base and implemented almost entirely(More)
Precision agriculture (PA) and information technology (IT) are closely interwoven. The former usually refers to the application of nowadays' technology to agriculture. Due to the use of sensors and GPS technology, in today's agriculture many data are collected. Making use of those data via IT often leads to dramatic improvements in efficiency. For this(More)
