Estimating ocean tide model uncertainties for electromagnetic inversion studies [PDF]

open access: yesAnnales Geophysicae, 2018
Over a decade ago the semidiurnal lunar M2 ocean tide was identified in CHAMP satellite magnetometer data. Since then and especially since the launch of the satellite mission Swarm, electromagnetic tidal observations from satellites are increasingly ...

Modeling complex systems [PDF]

open access: yesAgricultural Economics, 2010
AbstractEmpirical observations suggest that linear dynamics are not an adequate representation of ecological systems and that a realistic representation would require adoption of complex nonlinear dynamical systems with characteristics encountered in complex adaptive systems (CAS).

Impact of variable seawater conductivity on motional induction simulated with an ocean general circulation model [PDF]

open access: yesOcean Science, 2016
Carrying high concentrations of dissolved salt, ocean water is a good electrical conductor. As seawater flows through the Earth's ambient geomagnetic field, electric fields are generated, which in turn induce secondary magnetic fields.

Ontology-based modelling of architectural styles [PDF]

open access: yes, 2009
The conceptual modelling of software architectures is of central importance for the quality of a software system. A rich modelling language is required to integrate the different aspects of architecture modelling, such as architectural styles, structural

Modeling Sustainable Food Systems [PDF]

open access: yesEnvironmental Management, 2016
The processes underlying environmental, economic, and social unsustainability derive in part from the food system. Building sustainable food systems has become a predominating endeavor aiming to redirect our food systems and policies towards better-adjusted goals and improved societal welfare.

Formalising responsibility modelling for automatic analysis [PDF]

open access: yes, 2015
Modelling the structure of social-technical systems as a basis for informing software system design is a difficult compromise. Formal methods struggle to capture the scale and complexity of the heterogeneous organisations that use technical systems ...
