· Damping in Structural Dynamics: Theory and Sources. by Henrik Sönnerlind. March 14, 2019. If you strike a bowl made of glass or metal, you hear a tone with an intensity that decays with time. In a world without damping, the tone would linger forever. In reality, there are several physical processes through which the kinetic and elastic energy ...
Read MoreIn other words, torque T is the factor determined by L (the distance from the center of rotation) and load F. 3. How to determine torque transmission (without regard to machine efficiency) A gear''s transmission torque changes as it increases or decreases speed.
Read MoreMachine capability is measured in Cm and Cmk; it is a snapshot picture that shows how well a machine is performing right now in relation to the tolerance limits. Figure 6 shows some examples. When measuring machine capability you must not alter machine settings or change tools, materials, operators or measurement methods, stop the machine, etc.
Read More· Use a one-way ANOVA when you have collected data about one categorical independent variable and one quantitative dependent variable. The independent variable should have at least three levels (i.e. at least three different groups or categories). ANOVA tells you if the dependent variable changes according to the level of the independent variable.
Read MoreIt produces a normalized Euclidean distance calculation of 4.4721 for the data in columns 1 and 2. The raw Euclidean distance is 3.4655 If we change variable 5 to reflect the 1200 and 1300 values as in Table 2, the normalized Euclidean
Read MoreFactor analysis is a technique that is used to reduce a large number of variables into fewer numbers of factors. This technique extracts maximum common variance from all variables and puts them into a common score. As an index of all variables, we can use this score for further analysis. Factor analysis is part of general linear model (GLM) and ...
Read MoreFor other uses, see Normalizing constant. In statistics and applications of statistics, normalization can have a range of meanings.[1] In the simplest cases, normalization of ratings means adjusting values measured on different scales to a notionally common scale, often prior to averaging. In more complicated cases, normalization may refer to ...
Read MoreUpsample. Upsamples a given multi-channel 1D (temporal), 2D (spatial) or 3D (volumetric) data. The input data is assumed to be of the form minibatch x channels x [optional depth] x [optional height] x width . Hence, for spatial inputs, we expect a 4D Tensor and for volumetric inputs, we expect a 5D Tensor.

Read More· The Fama-French five-factor model which added two factors, profitability and investment, came about after evidence showed that the three-factor model was an inadequate model for expected returns because it''s three factors overlook a lot of the variation in average returns related to profitability and investment (Fama and French, 2015).
Read More· There are generally two types of factors: cross-sectional vs time-series. If you are modeling stock returns, cross-sectional factors are variables that are specific to an individual stock, such as its earnings yield, dividend yield, etc. In our previous blog post, we described how we provide 40 such factors to our subscribers for backtesting and live predictions.

Read MoreSummary. Factorial design has several important features. First, it has great flexibility for exploring or enhancing the "signal" (treatment) in our studies. Whenever we are interested in examining treatment variations, factorial designs should be strong candidates as the designs of choice. Second, factorial designs are efficient.

Read MoreA statistically significant result isn''t attributed to chance and depends on two key variables: sample size and effect size. Sample size refers to how large the sample for your experiment is. The larger your sample size, the more confident you can be in the result of the experiment (assuming that it is a randomized sample).

A Kruskal-Wallis test is used to determine whether or not there is a statistically significant difference between the medians of three or more independent groups. This test is the nonparametric equivalent of the one-way ANOVA and is typically used when the normality assumption is violated.
Read More· I''ve only encountered the term in machine learning contexts (that is, contexts where one is interested in accurate predictions and not necessarily theoretical inferences), but the concept can be applied to any statistical model. (My) definition: Variable importance refers to how much a given model "uses" that variable to make accurate predictions.
