The Color Purple

The article discusses the significance of the color purple, that coming from the murex shell, in the E. Mediterranean Bronze Age. Included are a brief resumé of the manufacture of purple dye, its history of use, and its coeval but quite different status and importance in both urban centers and peripheral areas in the period

MDL Patch Correspondences on Unlabeled Images with Occlusions

Automatic construction of Shape and Appearance Models from examples via establishing correspondences across the training set has been successful in the last decades. One successful measure for establishing correspondences of high quality is minimum description length (MDL). In other approaches it has been shown that parts+geometry models which model the appearance of parts of the object and the g

Numerical simulation of unsteady fluid flow and heat transfer in a transonic turbine stage

With the attempts to increase power, efficiency and thrust, modern gas turbines operate with combustor outlet temperatures of 1800-2000 K, which are far beyond the allowable metal temperatures. Turbine blades are exposed to these high temperature gases and may undergo severe thermal stress and fatigue. Thus, in order to develop optimal cooling strategies and reduce the heat transfer it is importan
