This technical report describes the construction of an inexpensive Ethernet Bridge built from an obsolete Pentium PC (IBM PC 300GL Pentium 166MMX ) and Ethernet cards. The report outlines a simple procedure for estimating the latency of the bridge. Results are presented for the timestamping accuracy of the bridge, the average latency and FreeBSD ping characteristics. The bridge can be used as a...

We introduce a data-driven model approximation method for nonlinear control systems, drawing on recent progress in machine learning and statistical dimensionality reduction. The method is based on embedding the nonlinear system in a high (or infinite) dimensional reproducing kernel Hilbert space (RKHS) where linear balanced truncation may be carried out implicitly. This leads to a nonlinear red...

We present a novel image encryption algorithm based on DNA subsequence operation. Different from the traditional DNA encryption methods, our algorithm does not use complex biological operation but just uses the idea of DNA subsequence operations (such as elongation operation, truncation operation, deletion operation, etc.) combining with the logistic chaotic map to scramble the location and the...

We find that the global symbolic dynamics of a diffusively coupled map lattice is well approximated by a very small local model for weak to moderate coupling strengths. A local symbolic model is a truncation of the full symbolic model to one that considers only a single element and a few neighbors. Using interval analysis, we give rigorous results for a range of coupling strengths and different...

This paper addresses forest height estimation for boreal forests at the test site of Edson in Alberta, Canada, using dual-baseline PolInSAR dataset measured by Intermap’s single-pass system. particular is acquired both ping-pong and non-ping-pong modes, which permit forming a TomoSAR configuration, i.e., an extreme configuration tomographic processing. A approach, based on polarimetric Capon MU...

This is a comment on the Kuranishi method of constructing analytic deformation spaces. It is based on a simple observation that the Kuranishi map can always be inverted in the category of L ∞-algebras. The L ∞-structure obtained by this inversion is used to define an " unobstructed " deformation functor which is always representable by a smooth pointed moduli space. The singular nature of the o...

A solution to the phase problem for the case of surface crystallography is presented. By oversampling a surface diffraction pattern along the continuous crystal-truncation rods, we can iteratively recover the phases of the complex structure factors of an unknown surface atomic geometry. Simple Fourier inversion of these structure factors directly yields a three-dimensional map of the electron d...
