A Concept of a Hybrid WDM/TDM Topology Using the Fabry-Perot Laser in the Optiwave Simulation Environment

Advances in Electrical and Electronic Engineering, 2011
The aim of this article is to point out the possibility of solving problems related to a concept of a flexible hybrid optical access network. The entire topology design was realized using the OPTIWAVE development environment in which particular test ...

The Imprint of Warm Dark Matter on the Cosmological 21-cm Signal [PDF]

, 2013
We investigate the effects of warm dark matter (WDM) on the cosmic 21-cm signal. If dark matter exists as WDM instead of cold dark matter (CDM), its non-negligible velocities can inhibit the formation of low-mass halos that normally form first in CDM ...

Angular Momentum Profiles of Warm Dark Matter Halos [PDF]

, 2001
We compare the specific angular momentum profiles of virialized dark halos in cold dark matter (CDM) and warm dark matter (WDM) models using high-resolution dissipationless simulations. The simulations were initialized using the same set of modes, except

Constraints on the warm dark matter model from gravitational lensing [PDF]

, 2001
Formation of sub-galactic halos is suppressed in warm dark matter (WDM) model due to thermal motion of WDM particles. This may provide a natural resolution to some puzzles in standard cold dark matter (CDM) theory such as the cusped density profiles of ...

Parallel Universes? Increasing Connections Between IPM and WDM

Human-Wildlife Interactions, 2017
Managing damage by wild vertebrates often is important, and wildlife damage management (WDM) has incorporated important tenets of integrated pest management (IPM).

Direct Detection of Warm Dark Matter in the X-ray [PDF]

, 2001
We point out a serendipitous link between warm dark matter (WDM) models for structure formation on the one hand and the high sensitivity energy range (1-10 keV) for x-ray photon detection on the Chandra and XMM-Newton observatories on the other.

Analysis of Impact of the Different Node Architectures and Wavelength Channel Protection on the Availability WDM Ring Networks

Communications, 2009
This paper investigates the availability of WDM (Wavelength Division Multiplying) ring networks. An analysis of different nodes, composed of passive and active components, is then carried out, as well as their availability.

Wavelength-division-multiplexing (WDM)-based integrated electronic–photonic switching network (EPSN) for high-speed data processing and transportation

Nanophotonics, 2020
Integrated photonics offers attractive solutions for realizing combinational logic for high-performance computing. The integrated photonic chips can be further optimized using multiplexing techniques such as wavelength-division multiplexing (WDM).

Nonlinear Evolution of Cosmological Structures in Warm Dark Matter Models [PDF]

, 2012
The dark energy dominated warm dark matter (WDM) model is a promising alternative cosmological scenario. We explore large-scale structure formation in this paradigm.
