Linguistically annotated treebanks play an essential part in the modern computational linguistics. The more complex the treebanks become, the more sophisticated tools are required for using them, namely for searching in the data. We study linguistic phenomena annotated in the Prague Dependency Treebank 2.0 and create a list of requirements these phenomena set on a search tool, especially on its...

this article introduces a systematic study for computational aspects of classical wavelet transforms over finite fields using tools from computational harmonic analysis and also theoretical linear algebra. we present a concrete formulation for the frobenius norm of the classical wavelet transforms over finite fields. it is shown that each vector defined over a finite field can be represented as...

Protein modeling is playing a more and more important role in protein and peptide sciences due to improvements in modeling methods, advances in computer technology, and the huge amount of biological data becoming available. Modeling tools can often predict the structure and shed some light on the function and its underlying mechanism. They can also provide insight to design experiments and sugg...

We have developed a suite of visualization and model construction tools for use in computing voltages and currents in the human thorax due to cardiac electrical activity. The programs support interactive digitization of MRI images, automatic generation, manipulation and editing of three-dimensional meshes, and display of both surface and volume potential distributions and volume current vectors.
