Further explorations of the α -particle optical model potential at low energies for the mass range A ≈45 -209 [PDF]

open access: yes, 2014
The recent high-precision measurements of $\ensuremath{\alpha}$-particle-induced-reaction data below the Coulomb barrier ($B$) make possible the understanding of limits and possible improvement of a previous optical model potential (OMP) for $\ensuremath{

Performance optimization of free-space optical communication protocols based on results from FSO demonstrations [PDF]

open access: yes, 2007
The mobile free-space optical channel mainly suffers from relatively long link outages, produced by short-term blockings of the line-of-sight (obstacles, clouds), pointing- and tracking-errors or deep signal-fades caused by index of refraction turbulence

Microphytobenthos Biomass and Diversity Mapping at Different Spatial Scales with a Hyperspectral Optical Model

open access: yesRemote Sensing, 2018
This work is an extension of the MicroPhytoBenthos Optical Model (MPBOM) workflow. The model was based on the observation that the biofilm itself has a negligible inherent reflectance and can be described solely by the ratio between its apparent ...

Elastic and inelastic scattering of 15N ions by 12C nuclei at energy 81 MeV

open access: yesЯдерна фізика та енергетика, 2018
ew angular distributions of the 15N + 12C elastic and inelastic scattering were measured at the energy Elab (15N) = 81 MeV. The data were analyzed within the coupled-reaction-channels method (CRC). The elastic and inelastic scattering as well as the more

Using a GPS-Aided Inertial System for Coarse-Pointing of Free-Space Optical Communication Terminals [PDF]

open access: yes, 2006
In the Capanina project, it has been shown that it is possible to use solely GPS positions for coarse-pointing of a stratospheric free-space optical communication terminal.

A torus model for optical flow [PDF]

open access: yesPattern Recognition Letters, 2020
We propose a torus model for high-contrast patches of optical flow. Our model is derived from a database of ground-truth optical flow from the computer-generated video \emph{Sintel}, collected by Butler et al.\ in \emph{A naturalistic open source movie for optical flow evaluation}.

Detection of second-order nonlinear optical magnetization by mapping normalized Stokes parameters [PDF]

open access: yes, 2013
A measurable magnetic (nonlocal) contribution to the second harmonic generation (SHG) of nonmagnetic materials is an intriguing issue related to chiral materials, such as biomolecules.
