The Annals of Mathematical Statistics, 1948 This paper is concerned with a simple mathematical model for a branching stochastic process. Using the language of family trees we may illustrate the process as follows. The probability that a man has exactly $r$ sons is $p_r, r = 0, 1, 2, \cdots$. Each of his sons (who together make up the first generation) has the same probabilities of having a given

Advanced Engineering Materials, EarlyView.The corrosion performance of AlSi7Mg and AlSi10Mg alloys produced through selective laser melting (SLM) was examined under compressive stress in a chloride environment. Electrochemical analyses, including open‐circuit potential (OCP), potentiodynamic polarization (CPP), and electrochemical impedance spectroscopy (EIS), were complemented by scanning ...

Advanced Engineering Materials, EarlyView.Thermomechanical fatigue tests of laser beam powder bed fusion (PBF‐LB) Inconel 718 show that the additively manufactured material reaches almost the lifetimes of conventionally‐rolled material under no‐dwell conditions. Introducing dwell times at the maximum temperature markedly reduces the lifetimes due to pronounced grain boundary sliding associated

, 2013 In dieser Arbeit wird ein stochastisches Parasit-Wirt Populationsmodell studiert. Die Wirtpopulation (Zellen) bildet dabei einen Galton-Watson Prozess (GWP), bei dem jede Zelle wiederum sich vermehrende Parasiten enthält, deren Nachkommen sich zufällig auf die Nachkommen der Zelle verteilen. Hergeleitet wird ein Zusammenhang zwischen dem asymptotischen
