A Low Power Current-Mode Binary-Tree WTA / LTA Circuit for Kohonen Neural Networks

Rafal Tomasz Dlugosz

A novel current-mode, binary-tree WTA / LTA circuit for application in analog Kohonen neural networks has been presented. In the proposed circuit input currents are first converted to step signals with equal amplitudes and different delays that are proport ...

Efficient evaluation of piecewise control laws defined over a large number of polyhedra

Colin Neil Jones

We consider the class of piecewise state feedback control laws applied to discrete-time systems, motivated by recent work on the computation of closed-form MPC controllers. The on-line evaluation of such a control law requires the determination of the stat ...

Photodissociation of Alkyl Iodides in Helium Nanodroplets I: Kinetic Energy Transfer

Marcel Drabbels, Andreas Braun

The photodissociation of (fluorinated) alkyl iodides in helium nanodroplets at a wavelength of 266 nm has been investigated by means of ion imaging techniques. It is found that a significant fraction of the created fragments escapes from the helium droplet ...

Self-organizing structured peer-to-peer overlay networks

A peer-to-peer overlay network is a logical network, built on top of a physical network. In contrast to classical client-server distributed architectures, peer-to-peer overlay networks allow location of resources without centralized control. Existing overl ...

Efficient raytracing of deforming point-sampled surfaces

Mark Pauly

We present efficient data structures and caching schemes to accelerate ray-surface intersections for deforming point-sampled surfaces. By exploiting spatial and temporal coherence of the deformation during the animation, we are able to improve rendering pe ...

Imaging the Translational Dynamics of CF3 in Liquid Helium Droplets

Marcel Drabbels, Andreas Braun

The translational dynamics of CF3 in liquid helium have been investigated by photodissociating CF3I dissolved in helium droplets consisting of several thousands of atoms. The velocity distribution of CF3 fragments that have escaped from the droplets has be ...

Inverse grading in granular flow

The current work concerns with the parametrical dependencies of inverse grading in granular flows from material properties of individual particles involved in the flow. The investigations were initiated and motivated by the search for an explanation of the ...

Distance transformations: fast algorithms and applications to medical image processing

Olivier Cuisenaire

Medical image processing is a demanding domain, both in terms of CPU and memory requirements. The volume of data to be processed is often large (a typical MRI dataset requires 10 MBytes) and many processing tools are only useful to the physician if they ar ...

Image Compression Using Binary Space Partitioning Trees

Martin Vetterli

For low bit-rate compression applications, segmentation-based coding methods provide, in general, high compression ratios when compared with traditional (e.g., transform and subband) coding approaches. In this paper, we present a new segmentation-based ima ...
