The EM iteration alternates between performing an expectation (E) step, which creates a function for the expectation of the log-likelihood evaluated using the current estimate for the parameters, and a maximization (M) step, which computes parameters maximizing the expected log-likelihood found on the E step. These parameter-estimates are then ...
Cura is an open source slicing application for 3D printers. [2] It was created by David Braam who was later employed by Ultimaker , a 3D printer manufacturing company, to maintain the software. Cura is available under LGPLv3 license. [ 3 ]
The formal definition of calibration by the International Bureau of Weights and Measures (BIPM) is the following: "Operation that, under specified conditions, in a first step, establishes a relation between the quantity values with measurement uncertainties provided by measurement standards and corresponding indications with associated measurement uncertainties (of the calibrated instrument or ...
A calibration curve plot showing limit of detection (LOD), limit of quantification (LOQ), dynamic range, and limit of linearity (LOL).. In analytical chemistry, a calibration curve, also known as a standard curve, is a general method for determining the concentration of a substance in an unknown sample by comparing the unknown to a set of standard samples of known concentration.

There are two main uses of the term calibration in statistics that denote special types of statistical inference problems. Calibration can mean a reverse process to regression, where instead of a future dependent variable being predicted from known explanatory variables, a known observation of the dependent variables is used to predict a corresponding explanatory variable; [1]
STEP-NC interface on a CNC, showing product shape and color-coded tolerance state. STEP-NC is a machine tool control language that extends the ISO 10303 STEP standards with the machining model in ISO 14649, [1] adding geometric dimension and tolerance data for inspection, and the STEP PDM model for integration into the wider enterprise.
From January 2008 to April 2010, if you bought shares in companies when James R. Ukropina joined the board, and sold them when he left, you would have a -18.1 percent return on your investment, compared to a -17.7 percent return from the S&P 500.
3D printing, or additive manufacturing, is the construction of a three-dimensional object from a CAD model or a digital 3D model. [1] [2] [3] It can be done in a variety of processes in which material is deposited, joined or solidified under computer control, [4] with the material being added together (such as plastics, liquids or powder grains being fused), typically layer by layer.
