Simulation of Inhomogeneous Refractive Index Fields Induced by Hot Tailored Forming Components

Advanced Engineering Materials, EarlyView.
This article presents a simulation model for simulating inhomogeneous refractive index fields (IRIF) in hot‐forged components, accounting for thermal influences and complex geometries. Through this simulation, a priori knowledge about the propagation of the IRIF can be obtained, allowing for the positioning of the component or an optical measurement ...

The Importance of Statistical Power Calculations

Headache: The Journal of Head and Face Pain, 2018
When planning research, collecting data, or interpreting an analysis, a crucial research design consideration is the size of the study sample. Typically, all of the individuals in a certain population of interest cannot be evaluated, so a researcher must

Statistical power calculations1 [PDF]

Journal of Animal Science, 2007
This article focuses on how to do meaningful power calculations and sample-size determination for common study designs. There are 3 important guiding principles. First, certain types of retrospective power calculations should be avoided, because they add no new information to an analysis.
