Fatigue analysis of catenary contact wires for high speed trains [PDF]

open access: yes, 2011
The fatigue fracture is one of the most critical failures which may occur on the high speed network because it is undetectable and it has a huge impact on traffic disruption.

Residence students' perceptions of institutional support for interracial contact at the University of Cape Town [PDF]

open access: yes, 2008
Includes bibliographical references (leaves 93-97).While inter-racial contact in university settings has been researched previously, the important concept of institutional support has not.

Generalized Normal Forms of Infinitesimal Symplectic and Contact Transformations in the Neighborhood of a Singular Point

open access: yes, 2012
Definition of generalized normal form for a system of ODEs corresponding to an infinitesimal symplectic or contact transformation near a singular point, with an arbitrary polynomial unperturbed part, and a method of its finding are introduced. Applicability of the introduced method to studying the critical phenomena in non-ideal media is shown.

Infinitesimal transformations and equivalence of the Lagrangian and Hamiltonian descriptions

open access: yes, 1993
Starting from the infinitesimal point of view, the need to enlarge the Hamiltonian principle for Hamiltonian dynamics is analysed. So-called Lagrangian transformations are introduced to demonstrate the complete equivalence, not only of the Lagrangian and

Conformal Classification of (k, μ)-Contact Manifolds [PDF]

open access: yes, 2010
First we improve a result of Tanno that says If a conformal vector field on a contact metric manifold M is a strictly infinitesimal contact transformation, then it is an infinitesimal automorphism of M by waiving the strictness in the hypothesis ...

An infinitesimal model for quantitative trait genomic value prediction

open access: yes, 2012
We developed a marker based infinitesimal model for quantitative trait analysis. In contrast to the classical infinitesimal model, we now have new information about the segregation of every individual locus of the entire genome.

Application of rigorous infinitesimal deformation approach to martensitic transformation observed in some Fe-Ni-C alloys

open access: yes, 2009
501-505 Rigorous infinitesimal deformation approach has been used to predict the phenomenological crystallographic parameters such as amount of lattice invariant shear, magnitude of total shape deformation, orientations of habit planes, etc.

Global consortium on security transformation : final narrative report, 2008-2010 [PDF]

open access: yes, 2010
The GCST fills the gap between citizens’ perceptions and government policies by encouraging the inclusion of new voices within policy discussions and analysis, especially those of the poor and insecure; making sure existing initiatives become more ...
