For a number of materials used in modern practice, calculations according to the classical theory elasticity give incorrect results. To ensure reliable operation structures, there is need for new theories. At present, particular interest practical applications asymmetric moment elasticity. In work, by method hypotheses, three-dimensional equations are reduced plates. The hypotheses plates formu...

this thesis deals essentially (but not from all aspects) with the extension of the notion of semigroup compactification and the construction of a general theory of semitopological nonaffine (affine) transformation semigroup compactifications. it determines those compactification which are universal with respect to some algebric or topological properties. as an application of the theory, it is i...

Micron-sized self-propelled (active) particles can be considered as model systems for characterizing more complex biological organisms like swimming bacteria or motile cells. We produce asymmetric microswimmers by soft lithography and study their circular motion on a substrate and near channel boundaries. Our experimental observations are in full agreement with a theory of Brownian dynamics for...

Assuming asymmetric information over farmer profits and zero transaction costs, prior literature has suggested that when regulating nonpoint source water pollution, a tax on management practices (inputs) can implement full-information allocations and is superior to a tax on estimated runoff. Using mechanism design theory under asymmetric information, this paper shows that under the same assumpt...

We use spin-density-functional theory to study the spacing between conductance peaks and the ground-state spin of 2D model quantum dots with up to 200 electrons. Distributions for different ranges of electron number are obtained in both symmetric and asymmetric potentials. The even/odd effect is pronounced for small symmetric dots but vanishes for large asymmetric ones, suggesting substantially...

Gossip protocols have been proposed as a robust and efficient method for disseminating information throughout large-scale networks. In this paper, we propose a compositional analysis technique to study formal probabilistic models of gossip protocols in the context of wireless sensor networks. We adopt a simple probabilistic timed process calculus for modellingwireless sensor networks. We equip ...

A formulation of Einstein gravity, analogous to that for gauge theory arising from the Chalmers-Siegel action, leads to a perturbation theory about an asymmetric weak coupling limit that treats positive and negative helicities differently. We find power counting rules for amplitudes that suggest the theory could find a natural interpretation in terms of a twistor-string theory for gravity with ...
