Impact of Mistiming on the Achievable Information Rate of Rake Receivers in DS-UWB Systems
Impact of Mistiming Information Rate of Rake Receivers DS-UWB Systems
2011/2/24
In this paper, we investigate the impact of mistiming on the performance of Rake receivers in direct-sequence ultra-wideband (DS-UWB) systems from the perspective of the achievable information rate.

On the Impact of Mutation-Selection Balance on the Runtime of Evolutionary Algorithms
Mutation-Selection Evolutionary Algorithms
2011/1/6
The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this interplay is still not completely understood. This paper presents...

The interplay between mutation and selection plays a fundamental role in the behaviour of evolutionary algorithms (EAs). However, this inter-play is still not completely understood.
Laboratory investigations of the impact of mineral dust aerosol on cold cloud formation
mineral dust aerosol cold cloud formation Laboratory
2010/12/28
Dust particles represent a dominant source of particulate matter (by mass) to the atmosphere, and their emission from some source regions has been shown to be transported on regional and hemispherical...
The vapor pressures and activities of dicarboxylic acids reconsidered: the impact of the physical state of the aerosol
dicarboxylic acids the physical state of the aerosol
2010/12/28
We present vapor pressure data of the C2 to C5 dicarboxylic acids deduced from measured evaporation rates of single levitated particles as both, aqueous droplets and solid crystals. The data of aqueou...

2010/12/20
Clouds constitute a large uncertainty in global climate modeling and climate change projections as many clouds are smaller than the size of a model grid box. Some processes, such as the rates of rain ...
Impact of biomass burning on ocean water quality in Southeast Asia through atmospheric deposition: eutrophication modeling
biomass burning ocean water quality Southeast Asia atmospheric deposition eutrophication modeling
2010/12/20
Atmospheric deposition of nutrients (N and P species) can intensify anthropogenic eutrophication of coastal waters. It was found that the atmospheric wet and dry depositions of nutrients was remarkabl...

Atmospheric nutrients have recently gained considerable attention as a significant additional source of new nitrogen (N) and phosphorus (P) loading to the ocean. The effect of atmospheric macro nutrie...
The impact of chemical differentiation of white dwarfs on thermonuclear supernovae
chemical differentiation thermonuclear supernovae
2011/1/10
Gravitational settling of 22Ne in cooling white dwarfs can affect the outcome of thermonuclear supernovae. We investigate how the supernova energetics and nucleosynthesis are in turn influenced by thi...
