In Zukunft müssen sich landwirtschaftliche Ackerbaubetriebe an die Folgen des Klimawandels operativ und strategisch anpassen, um langfristig wettbewerbsfähig zu bleiben. Mit Hilfe von einzelbetrieblichen Simulationsund Optimierungsmodellen lassen sich schon im Vorfeld Auswirkungen der Umweltveränderungen quantifizieren sowie sinnvolle einzelbetriebliche Anpassungsmaßnahmen ableiten. Dazu werden...

We compare the performance of two lexiconbased sentiment systems – SentiStrength (Thelwall et al., 2012) and SO-CAL (Taboada et al., 2011) – on the two genres of newspaper text and tweets. While SentiStrength has been geared specifically toward short social-media text, SO-CAL was built for general, longer text. After the initial comparison, we successively enrich the SO-CAL-based analysis with ...

Received ; accepted – 2 – ABSTRACT Chandra and XMM-Newton X-ray data reveal that the supersoft X-ray binary CAL 83 exhibits 38.4 minute pulsations at some epochs. These X-ray variations are similar to those found in some novae and are likely to be caused by nonradial pulsations the white dwarf. This is the first detection of pulsations in a persistent supersoft source.

The project is to design and implement a ‘wizard’ with the following functionality to support a traditional CAL learning environment. To continually monitor and collect data on individual and group student performance, to perform statistical analysis, to provide feedback for teachers, to enable students to contribute to the wizard’s experience, and to provide advice to the individual student.

This document describes the lookup table generator for the XTRP system.

In the spring of 1998, the Board of the Faculty of Biology of the University of Cambridge sanctioned a project to transform a long-standing traditional course in Medical Sociology, delivered to the first-year undergraduate medics, into a stand-alone computer-aided learning (CAL) package. The course consisted of 10 hour-long lectures, a number of tutorials (known in Cambridge as ‘supervisions’) ...
