We propose a method for non-linear data projection that combines Generative Topographic Mapping and Coordinated PCA. We extend the Generative Topographic Mapping by using more complex nodes in the network: each node provides a linear map between the data space and the latent space. The location of a node in the data space is given by a smooth nonlinear function of its location in the latent spa...

This paper presents an implementation of a switching observer design strategy to a piece-wise linear beam system comprising a flexible steel beam with a one-sided support. The switching observer design strategy guarantees asymptotic stability of the estimation error. Experimental and simulation results are presented to demonstrate the observer error stability and performance. Copyright c 2005 I...

We aim to visualize the external physical damages and distinct external phenotypic effects between mechanical and laser-assisted immobilized human spermatozoa using scanning electronic microscopy (SEM). Human spermatozoa were immobilized mechanically or with laser assistance for SEM examination and the membrane integrities were checked on both types of immobilized spermatozoa. We found evidence...

We develop a new regularization approach for 3D quantitative microwave tomography, based on a discontinuity adaptive model. The resulting reconstructions from sparse data points for 3D piecewise constant objects are encouraging. The reconstructions of more complex (piece-wise continuous) permittivity profiles from breast phantom data indicate potential for use in biomedical imaging.

The scaling hypothesis for the coupled chaotic map lattices (CML) is formulated. Scaling properties of the CML in the regime of extensive chaos observed numerically before is justified analytically. The asymptotic Liapunov exponents spectrum for coupled piece-wise linear chaotic maps is found.
