Experimental Studies of Turbulent Mixing in Impinging Jets

This thesis concerns the experimental study of mixing and flow characteristic in turbulent circular impinging jets without and with jet orifice manipulators (i.e. passive-fixed perturbations atthe nozzle exit), without and with swirl. The goal of the studies is to understand the basic mechanisms that control the mixing processes in turbulent impinging jets. The applications of such mixing processe

Implementation Strategy for an EBR-Solution

During the last decades, the level of automation has constantly increased in all types of manufacturing processes; discrete, continuous and batch. In addition to already existing automation systems, new and/or updated ones are being introduced at many production sites, e.g., various types of MES-systems. Today, the companies’ challenge is no longer to find the relevant automation/MES system, but r

Exploration and exploitation as learning strategies among entrepreneurs: Examining associations with entrepreneurial knowledge

In this paper we examine how exploration and exploitation, as two alternative learning strategies of entrepreneurs, influence the acquisition and development of entrepreneurial knowledge from prior career experience. In line with expectations based on experiential learning theory we find significant and direct associations between entrepreneurs’ career experience and their entrepreneurial knowledg

Abstract in German 1. Begriffsgeschichtliche Annäherung: Wovon sprechen wir, wenn wir die Begriffe 'Arbeit' und 'Beruf' im chinesischen Kontext verwenden? Welche (historischen) Entwicklungen haben diese Begriffe durchlaufen, wie unterscheiden sie sich von bestimmten deutschen/europäischen Entwicklungen? Welche Rolle spielen hierbei bestimmte Wendepunkte in der chinesischen Geschichte? 2. Offiziell

Another look at weak feedback polynomials in the nonlinear combiner

Feedback polynomials with low degree multiples of low weight should be avoided in linear feedback shift registers when used in nonlinear combiners. We consider another class of weak feedback polynomials, namely the class when taps are located in small groups. This class was introduced in 2004 demonstrating that the resulting distinguishing attack can sometimes be better than the one using low weig
