A section of a Hamiltonian system is hypersurface in the phase space system, usually representing set one-sided constraints (e. g., boundary, an obstacle or admissible states). In this paper we give local classification results for all typical singularities sections regular (non-singular) systems, problem equivalent to systems with constraints. particular, complete list exact normal forms funct...

We are pleased to introduce ‘Themed Sections’, as a new feature in Evolutionary Applications that we will be publishing two or three times a year, each comprising three to five papers that can be either original empirical work, metaalysis or synthesis. The first of this series was led by guest editors Ananias Escalante and Sudir Kumar and comprises three papers in the emerging interdisciplinary...

It was, and still is, a fundamental law of crystallography that fivefold rotational symmetry and three-dimensional (3D) lattice periodicity are mutually incompatible. With this in mind, the Israeli materials scientist Dan Shechtman did not trust his eyes when he inspected electron diffractograms of rapidly solidified Al-Mn. What he expected to see was either diffraction patterns with sharp Brag...

Executive Summary Traffic control in highway weaving sections is complicated since vehicles are crossing paths, changing lanes, or merging with through traffic as they enter or exit an expressway. There are two types of weaving sections: (a) single weaving sections which have one point of entry upstream and one point of exit downstream; and (b) multiple weaving sections which have more than one...
