On-line pulsewidth modulation (PWM) pattern generators for current–source rectifiers and inverters offer a number of control advantages over off-line optimized patterns. However, when implemented using the principles which apply to voltagesource inverter PWM pattern generators, the switching frequency is equal to: 1) the carrier frequency in standard carrier-based implementations and 2) a funct...

Implementing software product lines is a challenging task. Depending on the implementation technique the code that realizes a feature is often scattered across multiple code units. This way it becomes difficult to trace features in source code which hinders maintenance and evolution. While previous effort on visualization technologies in software product lines has focused mainly on the feature ...

We show that, in any typical transform coding systems, there is always a linear relationship between the coding bit rate and the percentage of zeros among the quantized transform coefficients, denoted by . Based on Shannon’s source coding theorem, a theoretical justification is provided for this linear source model. The physical meaning of the model parameter is also discussed. We show that it ...

In this paper we discuss the construction of software products from customer-specific feature selections. We address variability management with the Feature Description Language (FDL) to capture variation points of product line architectures. We describe feature packaging which covers selecting and packaging implementation components according to feature selections using the autobundle tool. Fi...

The position of a hydrodynamic dipole source, as encoded in a linear array of mechano-detecting neuromasts in the fish lateral line canal, was electrophysiologically investigated. Measured excitation patterns along the lateral line were compared to theoretical predictions and were found to be in good agreement. The results demonstrate that information on the position of a vibrating source from ...

|We have shown previously that non-stationary signals recorded in a static multi-path environment can often be recovered by simultaneously decorrelating varying second order statistics. As typical sources are often moving, however, the multi-path channel is not static. We present here an on-line gradient algorithm with adaptive step size in the frequency domain based on second derivatives, whic...

Despite its popularity, multichannel source demixing is intrinsically limited in real-world applications due to the model mismatch between the convolutive mixing model and the actual recordings. Varying number of sources, reverberation, diffuseness and spatial changes are common uncertainties that need to be handled. Post-processing is commonly adopted to compensate for these mismatches, genera...
