Non-destructive stress diagnostics is essential to optimise variable nutrient application with a minimal environmental load. The identifying characteristics when spectrally determining nitrogen, phosphorous and potassium stress in a canopy are dominantly nonspecific symptoms expressed as varying levels of chlorophyll in the leaves. The challenge is spectrally based discrimination between N, P a...

This paper describes an approach how to integrate virtual agents into the 3D multi-user online world Second Life. For this purpose we have implemented a new client software for Second Life that controls virtual agents (“bots”) and makes use of the Multimodal Presentation Markup Language 3D (MPML3D) to define their behavior. The technical merits and limitations of Second Life are discussed and s...

Previous work by Fulton et al. (2000) showed the development of a program for generating an “As Applied” map to assess uniform and variable-rate application of potash. The “As Applied” map was created using an “As Applied” file generated during field operation in conjunction with different application patterns determined by Fulton et al. (1999). While modifications are required to improve the p...

For aerial spray application, there is some question if off-target drift (both near and far) is influenced by which boom is spraying and the direction of propeller wash rotation. This information may be useful when switching off one boom close to a field boundary. The effect of alternate boom switching and propeller wash direction on aerial spray drift from a turbine-powered aircraft was invest...

Multi-agency response to mass-casualty incidents is a complex socio-technical domain with unique communication and information management needs to provide real-time situation awareness. We describe technical and human factors challenges to implementation of distributed alerts in a mobile, wirelessly enabled informatics platform based on a flexible, non-locking remote object architecture and pub...

Little information is currently available concerning temporal changes in nutrient transport following the addition of manure to cropland areas. This study was conducted to measure nutrient transport in runoff as affected by tillage and time following the application of beef cattle or swine manure to a site on which corn [Zea mays (L.)] was grown. Rainfall simulation tests were initiated 4, 32, ...

This note proves noninterference results (NI) for the secrecy analyses for LA and LAM presented in [1], using the inductive information ow analysis. This ow analysis is related to the secrecy typing in [1] in that, while the latter ensures safety of information ow, the former extracts ow of information. The presentation and study of ow analysis is restricted to its use in NI proofs: further stu...

In this paper, a system for analyzing the strategic adjustment of regional agricultural industries in China is briefly introduced, particularly on several system functions of database, region selection, statistics, comparative analysis and result presentation in terms of their technical realizations. The introduction is focused on the realized comparative advantageous agricultural analysis comp...

In this commentary I examine conceptual and methodological issues in Dr. Riordan’s (2012) presentation of three cases treated using Mitchell’s integrative model that combines aspects of Kernberg and Kohut’s technical stances in the treatment of narcissism. Riordan proposes that Mitchell’s integrative model provides a useful blend of Kernberg’s focus on defense and Kohut’s focus on empathy. He t...

Embodied conversational agents provide a promising option for presenting information to users. This contribution revisits a number of past and ongoing systems with animated characters that have been developed at DFKI. While in all systems the purpose of using characters is to convey information to the user, there are significant variations in the style of presentation and the assumed conversati...
