Situating Flatness
Our paper, ‘Human Geography without Scale’ (Marston et al. 2005), is developed in two parts: a critique that is immanent to scale, where we show that, even on the grounds of contemporary spatial theory, the concept is deficient; and a critique that is extrinsic to those grounds, where we make a contribution to an alternative ontology that does not rely on the transcendental abstraction of scale...
متن کاملFlatness of tracer clouds
The average concentration of a passive scalar advected from a point source by a multivariate normal velocity field is shown to deviate from a Gaussian profile. The flatness (kurtosis) is calculated using an asymptotic series expansion valid for velocity fields with short correlation times or weak space dependence. An explicit formula for the excess flatness at first order demonstrates maximum d...
متن کاملAutomatic Volume Leveler for Real Time Speech Applications
•Finds regions of quiet speech using the noise estimate and scales these regions using α = 0.99 to avoid noise amplification for low SNR’s •Identifies if the high amplitudes of the frame will be clipped after scaling and reduces the scale factors accordingly Key Aspects of the Volume Leveler •Tracks the noise level when the Voice Activity Detector(VAD) does not detect speech, so pure noise regi...
متن کاملTechnical Report CIT / CDS 94 - 006 California Institute of Technology DIFFERENTIAL FLATNESS AND ABSOLUTE EQUIVALENCEOF
This paper presents a formulation of diierential atness|a concept originally introduced by Fliess, Levine, Martin, and Rouchon|in terms of absolute equivalence between exterior diierential systems. Systems which are diierentially at have several useful properties which can be exploited to generate eeective control strategies for nonlinear systems. The original deenition of atness was given in t...
متن کاملMaximum flatness spectral modeling
The maximum entropy method obtains the flattest spectrum consistent with the given autocorrelation values, according to a specific flatness measure. In this correspondence, the suitability of the maximum flatness criterion for spectral estimation is discussed, concluding that it offers useful insight into the spectral models arising from the optimization approach.
