Forming limit curves are used as a parameter in finite element analysis to control the material's level of formability. In this research, forming limit diagram (FLD) of SS304L sheet was obtained by ABAQUSfinite element software. In practice, the experimental determination of a forming limit curve is a very time-consuming procedure which requires special and expensive equipment. Forming limit di...

Growth is a key cellular phenotype relevant in areas ranging from microbiology to cancer biology. Hence, quantitative measures of growth must be accurately estimated. Historically, many parametric models have been proposed, reviewed in ([1]). However, in our experience, growth curves rarely follow these idealistic behaviours. In practice, non-parametric models, in which curves are simply smooth...

Satisfactory spore preparations for testing hospital sterilizers can be made from B. stearothermophilus and comparatively simple methods for loading and drying the papers are considered to be valid. Each batch of spore papers should be calibrated by plotting dose-response curves for exposure to steam. A minimum standard in terms of the L.D.50 to moist heat is proposed and confidence limits sugg...

Plotting growth curves is a powerful graphical approach used in exploratory data analysis for continuous longitudinal data. However, plotted growth curves for multiple participants rapidly become uninterpretable with categorical data. Categorical data define specific states (e.g., being single, married, divorced), and these states do not necessarily need to represent any hierarchical order. Thu...

The “Q-curves” Q1(c) = c,Q2(c) = c + c, . . . , Qn(c) = (Qn−1(c)) + c = f c (0) have long been observed and studied as the shadowy curves which appear illusively — not explicitly drawn — in the familiar orbit diagram of Myrberg’s map fc(x) = x + c. We illustrate that Q-curves also appear implicitly, for a different reason, in a computer-drawn bifurcation diagram of x + c as well — by “bifurcati...

OBJECTIVE To explore the structure of Internet gaming disorder (IGD) criteria and their distribution according to the different severity level of IGD. The associations of psychiatric comorbidities to each IGD symptom and to the IGD severity were also investigated. METHODS Consecutively recruited 330 Korean middle school students underwent face-to-face diagnostic interviews to assess their gam...

radioactivedecay is a Python package for radioactive decay modelling. It contains functions to fetch data, define inventories of nuclides and perform calculations. The default nuclear dataset supplied with based on ICRP Publication 107, which covers 1252 radioisotopes 97 elements. code calculates an analytical solution matrix form the chain differential equations using double or higher precisio...

The overrt problem in inductive learning and the utility problem in speedup learning both describe a common behavior of machine learning methods: the eventual degradation of performance due to increasing amounts of learned knowledge. Plotting the performance of the changing knowledge during execution of a learning method (the performance response) reveals similar curves for several methods. The...
