Statistical Analysis of Experimental Data: A Fallacy in Judging Non‐Normal Distributions by a Logarithmic or Functional Probability Paper Plot

01 Dec 1949-Aircraft Engineering and Aerospace Technology (MCB UP Ltd)-Vol. 21, Iss: 12, pp 378-381
TL;DR: Gibrat, Divisia and Beckel as discussed by the authors showed that the summation curve of most skew distributions may also be represented as a straight line, if the argument x is traced as log (±x±a), where a is an arbitrarily chosen constant, which may, but need not, represent a physical condition.
Abstract: PROBABILITY paper was originally used to represent the summation curve of a Gaussian distribution as a straight line. Gibrat, Divisia in France and Daeves and Beckel in Germany have shown, that the summation curve of most skew distributions may also be represented as a straight line, if the argument x is traced as log (±x±a), where a is an arbitrarily chosen constant, which may, but need not, represent a physical condition.

TL;DR: In this article, a high-speed video camera, enabling recording and evaluation of the behaviour of a ceramic tool when dropped on the surface of a rotating testing rubber sample, was used for detailed analysis of the wear process.
Abstract: The issue of wear represents a very important role in the functionality of most products. The description of the wear process for very heavily strained rubber products, for instance off-road tire treads, conveyor belts for stone transport etc., is very essential. Sharp edges of stones and terrain roughness gradually cut (chip) off rubber parts. This wear considerably damages separate parts of the product and destroy it. In technical terminology, we call this type of wear CHIP - CHUNK effect. High-speed video camera, enabling recording and evaluation of the behaviour of ceramic tool when dropped on the surface of revolving testing rubber sample, was used for detailed analysis of the wear process.

TL;DR: The Maskontrolle is ein Teil des gesamten Kontrollwesens im Fabrikbetrieb and wird dementsprechend in dieses eingegliedert.
Abstract: Die Maskontrolle ist ein Teil des gesamten Kontrollwesens im Fabrikbetrieb und wird dementsprechend in dieses eingegliedert. Die Kontrolle wiederum ist eine Erganzung der Fertigung und dient zur Uberwachung der Personen, Fertigungsmittel und Erzeugnisse, so das diese brauchbar sind und Verluste und Schaden vermieden werden. Organisatorisch ist die Kontrolle in vielen Betrieben von der Fertigungsleitung getrennt, wie in Abb. 81-1 veranschaulicht.
