Weyl gravity has been advanced in the recent past as an alternative to General Relativity (GR). The theory has had some success in fitting galactic rotation curves without the need for copious amounts of dark matter. To check the viability of Weyl gravity, we propose two additional classical tests of the theory: the deflection of light and time delay in the exterior of a static spherically symm...

We present a model for the electrophysiology in the heart to handle the electrical propagation through the Purkinje system and in the myocardium, with two-way coupling at the Purkinje-muscle junctions. In both the subproblems the monodomain model is considered, whereas at the junctions a resistor element is included that induces an orthodromic propagation delay from the Purkinje network towards...

In this paper the efficient implementation of numerical software for solving delay differential equations is addressed. Several strategies that have been developed over the past 25 years for improving the efficiency of delay differential equation solvers are described. Of particular interest is a new method of automatically constructing the network dependency graph used in tracking derivative d...

Trimming procedures are an important part of the sequence analysis pipeline in an EST Sequencing Project. In general, trimming is done in several phases, each one detecting and removing some kind of undesirable artifact, such as low quality sequence, vectors or adapters sequence, and contamination. However, this strategy often results in a phase being unable to recognize its target because part...

The nonstationary nature of signals and nonlinear systems require the time-frequency representation. In time-domain signal, frequency information is derived from the phase of the Gabor’s analytic signal which is practically obtained by the inverse Fourier transform. This study presents time-frequency analysis by the Fourier transform which maps the time-domain signal into the frequency-domain. ...

Analysis of jitter due to call-level fluctuations CWI's research has a theme-oriented structure and is grouped into four clusters. Listed below are the names of the clusters and in parentheses their acronyms. Analysis of jitter due to call-level fluctuations ABSTRACT In communication networks used by constant bit rate applications, call-level dynamics (i.e., entering and leaving calls) lead to ...
