Towards a Scientific Model Management System

Stefano Spaccapietra, José Antonio Fernandes de Macedo

Computational models of biological systems aim at accurately simulating in vivo phenomena. They have become a very powerful tool enabling scientists to study complex behavior. A side effect of their success Unfortunately exists and is observed as an increa ...

USEtox-the UNEP-SETAC toxicity model: recommended characterisation factors for human toxicity and freshwater ecotoxicity in life cycle impact assessment

Jérôme Payet

Background, aim and scope In 2005, a comprehensive comparison of life cycle impact assessment toxicity characterisation models was initiated by the United Nations Environment Program (UNEP)-Society for Environmental Toxicology and Chemistry (SETAC) Life Cy ...

Shear strength in one- and two-way slabs according to the critical shear crack theory

Aurelio Muttoni, Miguel Fernández Ruiz

Currently, there is no generally-accepted theory giving a physical explanation of the shear strength in one- and two-way slabs. Furthermore, for members without transverse reinforcement, shear strength is estimated in most codes of practice following empir ...

First-principles description of ferroelectric/electrode interfaces and properties of not very thin ferroelectric capacitors

Nava Setter, Alexander Tagantsev, Guido Gerra

We formulate an approach to the size effect problem in ferroelectric-electrode systems where ab initio calculations are combined with a phenomenological framework. The parameters of the model can be extracted from the calculations, while experimentally ver ...

Theory of trapped polaritons in patterned microcavities

Vincenzo Savona, Davide Sarchi, Pierre Lugan

We consider the system of a quantum well embedded in a planar semiconductor microcavity with a shallow circular mesa patterned on top of the cavity spacer. For this system we develop the linear coupling theory of polaritons. We then compute polariton eigen ...

Grounding is not Shared Understanding: Distinguishing Grounding at an Utterance and Knowledge Level

Mauro Cherubini, Jakko Van der Pol

This paper argues that for the study and facilitation of collaborative learning, existing theories of grounding such as that of Clark and Shaefer [5] cannot be applied without adjustments. When comparing collaborative learning and conversation, four dimens ...

Know-how and know-why in biochemical engineering

Urs von Stockar, Ian William Marison, Sergio Valentinotti, Christopher Cannizzaro, Christoph Herwig

A review, with refs. This contribution analyzes the position of biochem. engineering in general and bioprocess engineering particularly in the force fields between fundamental science and applications, and between academia and industry. By using culture te ...

Onset of neoclassical tearing modes on JET

Olivier Sauter, Duccio Testa

A detailed study has been made of the onset and behaviour of (m = 3, n = 2) neoclassical tearing modes (NTMs) on JET, validating many of the underlying concepts in NTM physics. In particular, fitting onset thresholds in terms of the correctly motivated phy ...

Strengthening MDA by Drawing from the Living Systems Theory

Alain Wegmann, Otto Preiss

OMGs Model Driven Architecture initiative comes at a time where information system builders and integrators have realized that application design and thus application interoperability is not primarily a technology issue but is about understanding different ...
