Vacuum‐Formed Composites Based on a Polyolefin and a High Content of Biomass‐Waste Fillers
Advanced Engineering Materials, EarlyView.It is shown here that by the use of a very ductile polymer matrix, it is possible to vacuum‐form products that contain up to 25% of hard biofillers with still ductile properties. The results are promising and opens up for the use of engineered biocomposites derived from industrial side‐stream biofillers in vacuum‐formed products. A strategy to increase

Advanced Engineering Materials, EarlyView.When realized as inserts in high‐pressure die casting, aluminum cooling channels for electric powertrain components and similar applications typically require a stabilizing filler to survive the process. The present study investigates relinquishing this filler using additively manufactured inserts promising performance improvements.

W‐Based Thin Film Metallic Glasses Doped with Ni, Zr, and B for Industrial Applications
Advanced Engineering Materials, EarlyView.This work is the first to deal with a comprehensive comparison of two metallic glass systems, W–Zr–B and W–Ni–B, in terms of their suitability for specific industrial applications. Their mechanical and tribological properties are compared and discussed in combination with structural homogeneity on different types of technically relevant substrates and ...

Advanced Engineering Materials, EarlyView.This article investigates residual stress formation during single‐spot nanosecond laser ablation of stainless steel. Experimental validation and a parametric study using finite element simulations are employed to analyze thermal effects, ablation dynamics, and stress evolution.

Multivariate Generalizations of the Proportional Hazards Model
Journal of the Royal Statistical Society. Series A (General), 1985Die Motivation für die vorliegende Arbeit stammt aus Fragestellungen der Medizin, insbes. aus klinischen Versuchen und epidemiologischen Studien in der Erforschung von Krebs- und Kreislauferkrankungen. So werden zum Beispiel herzkranke Vater-Sohn-Paare herausgegriffen und das Alter beim Tode bzw.

Sequential analysis of the proportional hazards model [PDF]
Biometrika, 1983 Abstract : For the proportional hazards model of survival analysis, an appropriate large sample theory is developed for cases of staggered entry and sequential analysis. The principal techniques involve an approximation of the score process by a suitable martingale and a random rescaling of time based on the observed Fisher information.
