JPEG2000 is the latest international standard for compression of still images. Although the JPEG2000 codec is designed to compress images, we illustrate that it can also be used to compress other signals. As an example, we illustrate how the JPEG2000 codec can be used to compress electrocardiogram (ECG) data. Experiments using the MITBIH arrhythmia database illustrate that the proposed approach...

Publicly owned companies, their officers and major investors are required to file regular disclosures with the Securities and Exchange Commission (SEC). To improve accessibility to these public documents, the SEC began developed the EDGAR (Electronic Data Gathering, Analysis and Retrieval) electronic disclosure system. This system provides ready, free access to all electronic filings made since...

This paper describes how to extend the performance of a highly energy efficient general purpose DSP by generating accelerators using C-level algorithm descriptions. The result is an equally energy efficient, economical implementation of that algorithm or algorithms.

We calculate the pressure in QCD with two and three light quarks on a lattice of size 16 3 × 4 using tree level improved gauge and fermion actions. We argue that for temperatures T > ∼ 2T c systematic effects due to the finite lattice cutoff and non-vanishing quark masses are below 15% in this calculation and give an estimate for the continuum extrapolated pressure in QCD with massless quarks. ...

Detailed profile of the context formation process in EBCOT is analyzed to get an insight into the characteristics of the ope...
