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)
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)
Eine effiziente Kalkdüngung kann nur dann erfolgen, wenn der pH-Wert kleinräumig bekannt ist. Aus ökonomischen Gründen ist die Ermittlung mit der herkömmlichen Herangehensweise bei der Bodenbeprobung und Analyse nicht sinnvoll. Ein Sensor der Firma Veris kann indessen während der Überfahrt den pH-Wert messen, nutzt jedoch eine andere Analytik. Im Beitrag(More)
