The GMD Method for Inductance Calculation Applied to Conductors with Skin Effect

open access: yesAdvanced Electromagnetics, 2017
The GMD method (geometric mean distance) to calculate inductance offers undoubted advantages over other methods. But so far it seemed to be limited to the case where the current is uniformly distributed over the cross section of the conductor, i.e. to DC

Uniformity of the pseudomagnetic field in strained graphene

open access: yes, 2015
We present a study on the uniformity of the pseudomagnetic field in graphene as a function of the relative orientation between the graphene lattice and straining directions.

Some non-existence results for distance-$j$ ovoids in small generalized polygons

open access: yes, 2016
We give a computer-based proof for the non-existence of distance-$2$ ovoids in the dual split Cayley hexagon $\mathsf{H}(4)^D$. Furthermore, we give upper bounds on partial distance-$2$ ovoids of $\mathsf{H}(q)^D$ for $q \in \{2, 4\}$.Comment: 10 ...

Rhombus Tilings of a Hexagon with Two Triangles Missing on the Symmetry Axis

open access: yes, 1998
We compute the number of rhombus tilings of a hexagon with sides n, n, N, n, n, N, where two triangles on the symmetry axis touching in one vertex are removed.

Automorphisms of the Torelli complex for the one-holed genus two surface

open access: yes, 2013
Let S be a connected, compact and orientable surface of genus two having exactly one boundary component. We study automorphisms of the Torelli complex for S, and describe any isomorphism between finite index subgroups of the Torelli group for S.

CrSi2 Hexagonal Nanowebs

open access: yesJournal of the American Chemical Society, 2010
Single-crystalline CrSi(2) nanostructures with a unique hexagonal nanoweb morphology have been successfully synthesized for the first time. These nanowebs span 150-200 nm and are composed of nanowire segments with a thickness of 10-30 nm. It is proposed that surface charges on the {101̅0} sidewalls and the minimization of electrostatic energy induce ...

The future of geospatial intelligence

open access: yesGeo-spatial Information Science, 2017
For centuries, humans’ capacity to capture and depict physical space has played a central role in industrial and societal development. However, the digital revolution and the emergence of networked devices and services accelerate geospatial capture ...
