We describe a new approach for testing MIDI performance characteristics, which is both inexpensive and highly accurate. Following a description of the test method, actual results for a number of MIDI interface technologies are presented. These results show that jitter and latency performance of newer (USB-based) interfaces is actually two to three times worse than older MIDI interface technolog...

Model-driven performance prediction methods require detailed design models to evaluate the performance of software systems during early development stages. However, the complexity of detailed prediction models and the semantic gap between modelled performance concerns and functional concerns prevents many developers to address performance. As a solution to this problem, systematic model refinem...

Network traffic processes can exhibit properties of self-similarity and long-range dependence, i.e., correlations over a wide range of time scales. However, as already shown by several authors for the case of a single queue, the second-order behavior at time scales beyond the so-called correlation horizon or critical time scale does not significantly affect network performance. In this work, we...

Here we investigate the practical feasibility of performing soundfield reproduction throughout a three-dimensional area by controlling the acoustic pressure measured at the boundary surface of the volume in question. The main aim is to obtain quantitative data showing what performances a practical implementation of this strategy is likely to yield. In particular, the influence of two main limit...
