In this article we define an Eulerian level set method for a partial differential equation on an evolving hypersurface Γ (t) contained in a domain Ω ⊂ R. The key idea is based on formulating the partial differential equations on all level set surfaces of a prescribed time dependent function Φ whose zero level set is Γ (t). The resulting equation is then solved in one dimension higher but can be...

Following some Arnol’d results relative to the geometry underlying the dynamics of a perfect incompressible fluid [3] (geodesics of left-invariant metrics on Lie groups), the linear differential equation relative to a Lagrangian stability analysis are established. This differential equation, called Jacobi equation, describes, for the same fluid element, the time evolution of the difference betw...

Using a bioeconomic model with two separate forms of uncertainty (a diffusion process and a jump process) a perturbation method is used to determine optimal reserve size for a harvested population with density-dependent growth. The results show that the benefits of reserves are understated in deterministic models and that, even with optimal harvesting, risk neutrality, a persistent population a...

A random tiling of rectangles and triangles displaying a decagonal phase is solved by Bethe Ansatz. Analogously to the solutions of the dodecagonal square triangle and the octagonal rectangle triangle tiling an exact expression for the maximum of the entropy is found.

To allow connectivity between the General Switched Telephone Network facsimile service (GSTN fax) and the e-mail-based Internet Fax service (i-fax) an "Internet Fax Gateway" is required. This document provides recommendations for the functionality of Internet Fax Gateways. In this context, an "offramp gateway" provides facsimile data transmission from i-fax to GSTN fax; vice versa, an "onramp g...

We give an alternative derivation of two Painlevé hierarchies. This is done by constructing generalized scaling reductions of the Korteweg-de Vries and dispersive water wave hierarchies. We also construct a generalized scaling reduction of Burgers hierarchy. Corresponding author: P. R. Gordoa. Tel: +34 91 4888243; Fax: +34 91 488 7338; email: [email protected]

The vast majority of research on sport consumers fails to utilize a theoretical understanding of motivation to examine behaviour. Self-Determination Theory was used to develop a new understanding of sport consumer motivation. Sport consumer motivation is conceptualized as representing autonomy and control orientations that energize a desire to engage in sport goal directed behaviour to acquire ...
