Meta-Constraints: to aid interaction and to provide explanations

We explore the use of meta-constraints as a way of providing explanations to the user. Meta-constraints can provide a summary of the state of the CPS, and thus form a way of leaving out a large amount of detail that would be unhelpful to the user when dealing with a large problem. The ideas are illustrated through the problem of University students selecting modules for their studies

Membrane separation in flow injection analysis : Gas Diffusion

A general expression is derived for the membrane transport process in a flow-through unit as commonly used in flow injection systems. The validity of the formulae was tested for gas-diffusion membranes by using compounds with different volatilities such as ammonia, carbon dioxide and acetic acid. Several microporous hydrophobic membranes were tested. A new module design is proposed

Assigning Satisfaction Values to Constraints: An Algorithm to Solve Dynamic Meta-Constraints

The model of Dynamic Meta-Constraints has special activity constraints which can activate other constraints. It also has meta-constraints which range over other constraints. An algorithm is presented in which constraints can be assigned one of five different satisfaction values, which leads to the assignment of domain values to the variables in the CSP. An outline of the model and the algorithm is presented, followed by some initial results for two problems: a simple classic CSP and the Car Configuration Problem. The algorithm is shown to perform few backtracks per solution, but to have overheads in the form of historical records required for the implementation of state.Comment: 11 pages.

Nudge, nudge, think, think: experimenting with ways to change civic behaviour

Peter John‘s recent book investigates how to get the best out of nudge theories, considering positive behaviour changes in recycling, volunteering, voting, and petitioning, and provides some unexpected insights about some interventions, finds Sander van der Linden.

Trump, Populism, Fascism, and the Road Ahead

This review essay offers a discussion of some recent studies that help to explain the election of Donald Trump as president of the USA. The studies examine Trump as “media spectacle,” analyze his support among Tea Partiers, and discuss his backing by the white working class left behind by neoliberalism and global capitalism. Special attention is given to two questions: Is Trump a rightwing populist or closer to a fascist? Relatedly, is Trump a threat to liberal democracy? The essay concludes with some suggestions of how to move beyond Trump

Modelling of Elastic Gearboxes Using a Generalized Gear Contact Model

The object of this paper is to present an universal model that describes the gear contact between two gears in a planar environment. The model includes elastic effects between the gear wheels. Using this model it is possible to create arbitrary spur gear connections as well as all kinds of epicyclic gearing configurations by supplying the proper external constraints. The presented model is implementated in the Modelica language and Dymola is used for the simulations
