Semiotic Landscapes: Scaling Indonesian Multilingualism

Multilingualism on the Internet

According to a September 2004 compilation (Almanac 2004), the number of the world’s population now online is approaching an extraordinary one billion. Fifteen countries account for about 70% of the total individuals online today. The United States has the largest single proportion online of any country, or 20% of the total. This reflects not merely its relatively large population size and advan...

Evaluating empirical scaling relations of pattern metrics with simulated landscapes

Landscape patterns demonstrate scale-dependent properties that have been parsimoniously described by empirical scaling functions. These functions, derived from multiple-scale analysis of real landscapes, are evaluated here for their generality and robustness via a series of simulated landscapes with known landscape patterns. A factorial design was used to generate these landscapes, varying the ...

Scaling of a Slope: the Erosion of Tilted Landscapes

We formulate a stochastic equation to model the erosion of a surface with fixed inclination. Because the inclination imposes a preferred direction for material transport, the problem is intrinsically anisotropic. At zeroth order, the anisotropy manifests itself in a linear equation that predicts that the prefactor of the surface height-height correlations depends on direction. The first higher-...

Approximate scaling properties of RNA free energy landscapes.

RNA free energy landscapes are analysed by means of "time-series" that are obtained from random walks restricted to excursion sets. The power spectra, the scaling of the jump size distribution, and the scaling of the curve length measured with different yard stick lengths are used to describe the structure of these "time series". Although they are stationary by construction, we find that their ...
