We consider the problem of jointly allocating channel center-frequencies and bandwidths for IEEE 802.11 wireless LANs (WLANs). The bandwidth used on a link significantly affects both the capacity experienced on this link and the interference produced on ne ...

The role of Rayleigh Waves in Granular Solids

Alessandro Spadoni, Bart Van Damme

Wave propagation in granular solids is found to have at least two regimes: a low-frequency ballistic signal and a high-frequency diffusive tail. The latter is attributed to granules clapping or elastic waves within the granules themselves. The low frequenc ...

Transverse spin penetration length in metallic spin valves

Jean-Philippe Ansermet

A semiclassical description of diffusive spin transport in spin valves, which takes into account the transverse components of spin accumulation, is used to calculate the second harmonic voltage response to a low-frequency current. The description is applie ...

Distributed Spectrum Assignment for Home WLANs

Patrick Thiran, Julien Pierre Sacha Herzen, Ruben Merz

We consider the problem of jointly allocating chan- nel center frequencies and bandwidths for IEEE 802.11 wireless LANs (WLANs). The bandwidth used on a link affects sig- nificantly both the capacity experienced on this link and the interference produced o ...

Bounding the Polynomial Approximation Errors of Frequency Response Functions

Zlatko Emedi

Frequency response function (FRF) measurements take a central place in the instrumentation and measurement field because many measurement problems boil down to the character- ization of a linear dynamic behavior. The major problems to be faced are leakage ...

Funnelling of rf current via a plasmoid through a grid hole in an rf capacitive plasma reactor

Christoph Hollenstein, Alan Howling, Michaël Chesaux

The boundaries of capacitively coupled radio-frequency (rf) plasma reactors generally include at least one grounded metal grid or perforated plate for purposes of gas flow or diagnostic access. When increasing the rf power, an intense localized plasma (a p ...

Interaural correlation discrimination from diffuse field reference correlations

Christof Faller, Andreas Walther

Just noticeable differences in interaural correlation (rho-jnds) from diffuse sound field reference correlations are obtained. In a three-interval, three-alternative forced-choice procedure, rho-jnds are measured for positive and negative deviations from n ...

Assessment of active electroacoustic absorbers as low-frequency modal dampers in rooms

Hervé Lissek, Romain Boulandet, Etienne Thierry Jean-Luc Rivet, Iris Rigas

In small to medium size rooms, natural room modes may severely strengthen the annoyance of low frequency noises, such as traffic or equipment noise. Moreover, there is an actual technological gap in the state-of-the-art concerning low-frequency treatments, ...

High-resolution detection of Brownian motion for quantitative optical tweezers experiments

Sylvia Jeney, Matthias Grimm

We have developed an in situ method to calibrate optical tweezers experiments and simultaneously measure the size of the trapped particle or the viscosity of the surrounding fluid. The positional fluctuations of the trapped particle are recorded with a hig ...
