Suspended silicon waveguides for long-wave infrared wavelengths
J. Soler Penadés, A. Sánchez-Postigo, M. Nedeljkovic +12
In this paper we report suspended silicon waveguides operating at a wavelength of 7.67 mm with a propagation loss of 3.1 ? 0.3 dB/cm. To our knowledge this is the first demonstrati…
Totally umbilic null hypersurfaces in generalized Robertson-Walker spaces
Manuel Gutiérrez, Benjamín Olea
We show that there is a correspondence between totally umbilic null hypersurfaces in generalized Robertson-Walker spaces and twisted decompositions of the fibre. This allows us to…
A Hankel matrix acting on spaces of analytic functions
Daniel Girela, Noel Merchán
If is a positive Borel measure on the interval we let be the Hankel matrix with entries , where,…
New properties on normalized null hypersurfaces
Cyriaque Atindogbe, Manuel Gutiérrez, Raymond Hounnonkpe
Rigging technique introduced in \cite{bi0} is a convenient way to address the study of null hypersurfaces. It offers in addition the extra benefit of inducing a Riemannian structur…
Bivariate Rician shadowed fading model
J. Lopez-Fernandez, J. F. Paris, E. Martos-Naya
In this paper we present a bivariate Rician shadowed fading model where the shadowing is assumed to follow a Nakagami- distribution. We derive exact expressions involving a sing…
A Simulation Tool for tccp Programs
María-del-Mar Gallardo, Leticia Lavado, Laura Panizo
The Timed Concurrent Constraint Language tccp is a declarative synchronous concurrent language, particularly suitable for modelling reactive systems. In tccp, agents communicate an…
