How Far Are Two Symmetric Matrices From Commuting? With an Application to Object Characterisation and Identification in Metal Detection

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Examining the extent to which measurements of rotation matrices are close to each other is challenging due measurement noise. To overcome this, data is typically smoothed, and the Riemannian and Euclidean metrics are applied. However, if rotation matrices are not directly measured and are instead formed by eigenvectors of measured symmetric ...

Interaction of marine geodesy, satellite technology and ocean physics [PDF]

The possible applications of satellite technology in marine geodesy and geodetic related ocean physics were investigated. Four major problems were identified in the areas of geodesy and ocean physics: (1) geodetic positioning and control establishment ...

A Biophysical Approach to the Design of Networks of Communication Systems

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT Inspired by the growth dynamics of the protist Physarum polycephalum, we employ a formalism that describes adaptive, incompressible Hagen‐Poiseuille flows on channel networks to identify graphs connecting different nodes within Euclidean space. These graphs are either suboptimal or optimal relative to their length.

Pomen digitalnega batimetričnega modela za trajnostni razvoj morja : The Significance Of Digital Bathymetric Model For Sustainable Development Of The Sea [PDF]

Geodetski Vestnik, 2008
Geodezija kot stroka ima pomembno vlogo pri pripravi prostorskih podatkov, ki omogočajo trajnostno načrtovanje, ne le prostora na kopnem, temveč tudi na morju.

Comments on the RG‐Flow in Open String Field Theory

Fortschritte der Physik, EarlyView.
Abstract We define a metric G$G$ on the KBc‐subalgebra modulo gauge and describe the worldsheet RG‐flow as the gradient flow of the action of cubic open string field theory, where the flow lines are kink‐solitons. In particular, for a constant tachyon the gradient flow equations are equivalent to the RG‐equations. Additionally, a more general family of

Research Article. Towards a tidal loading model for the Argentine-German Geodetic Observatory (La Plata)

Journal of Geodetic Science, 2017
We present a regionalized model of ocean tidal loading effects for the Argentine-German Geodetic Observatory in La Plata. It provides the amplitudes and phases of gravity variations and vertical deformation for nine tidal constituents to be applied as ...
