A precursor in waterhammer analysis – rediscovering
In 1883 Johannes von Kries published the theory of waterhammer in a study of blood flow in arteries. He derived the “Joukowsky formula” before Joukowsky (1898) and Frizell (1898) did. He considered skin friction in unsteady laminar flow and thus derived formulas for wave attenuation and line pack. The theory was confirmed by experimental results obtained in rubber hoses. In 1892 he published th...
متن کاملProcessor pipelines in WCET analysis
Due to their nature, hard real-time embedded systems (e.g. flight control systems) must be guaranteed to satisfy their time constraints under all operating conditions. The provision of such guarantee relies on safe and precise estimates of the worst-case execution time (WCET) of tasks. As the execution time depends on both the program and the architecture running it, the growing sophistication ...
متن کاملAnalysis of domino effect in pipelines.
Parallel pipelines are frequently installed over long distances, due to the difficulty in creating or maintaining the required corridor. This implies that a release in one pipeline can seriously affect another one. The main risks associated with this domino effect are erosion by fluid-sand jets and the thermal action of jet fires. In this paper a survey has been performed on the accidents that ...
متن کاملMorphological Analysis of Mammograms Using Visualization Pipelines
The aim of this study is to detect masses in mammograms through pipelining sequences of visualization operators. Such sequences act as morphological filtering operators for identifying objects of interest. This is done using series of rendering operators including edge detection, smoothing, filling small holes, coloring various densities, joining broken boundaries and eliminating small projecti...
