The ThreadRadar visualization for debugging concurrent Java programs

Due to non-deterministic behavior and thread interleaving of concurrent programs, the debugging of concurrency and performance issues is a rather difficult and often tedious task. In this paper, we present an approach that combines statistical …

Instability phenomena of lean hydrogen/oxygen/inert-gas premixed flames on a flat burner

Hydrogen attracts attention as one of favorable fuels because of zero emissions of carbon dioxide and particulates. In hydrogen-air premixed flames, the burning velocity is very high and the flame is invisible, so that it is necessary to control …

Dynamic delayed detached-eddy simulation and acoustic analogy analysis of unsteady flow through a sudden expansion pipe

In the present study, the unsteady flow through a sudden expansion pipe with an expansion ratio of 1:3 is numerically modeled using dynamic delayed detached-eddy simulation (dynamic DDES), and the flow noise mechanism and the downstream noise …

Compact tetrahedralization-based acceleration structures for ray tracing

The most common approach to speed up ray-surface intersection calculations in ray tracing is to use spatial subdivision structures that partition the scene to enclose the polygons in different volumes. Ray-tracing algorithms can avoid ray-triangle …
