Spectral flatness or tonality coefficient, also known as Wiener entropy, is a measure used in digital signal processing to characterize an audio spectrum. Spectral flatness is typically measured in decibels, and provides a way to quantify how much a sound resembles a pure tone, as opposed to being noise-like. WebOct 31, 2024 · The torque density of the axial-gap motors and the radial-gap motors is evaluated, using a finite element method (FEM). Simulation results clarified that the boundary between the two types of the motors is from 0.4 to 0.6 in terms of the flatness ratio, which determines the best approach to maximize the torque density of the motors.
WebThe effect of the profile of the hot coil on the flatness and the profile of cold-rolled strip has been studied by means of samples from a tandem cold mill of Pohang Iron and Steel Co., South Korea. ... Although the crown ratio of the cold strip became larger than that of the hot strip as the measurement point approached the strip edge, the ... WebApr 15, 2024 · In another aspect, some studies proposed that important aspects of particle form are represented by the elongation and flatness ratio [18, 38]. In the characterization of elongation and flatness' influence on particle shape, Zingg classification is the most widely used quantitative method [18, 42]. Thus, we choose the sample particles by Zingg ...
WebMay 3, 2013 · Highlights We develop a novel model for the thermal conductivity (TC) of graphene composites. We adopt a new concept, flatness ratio, into the theoretical model. TC predictions show a good agreement with reported experimental data. Flatness ratio acts as a dominant role in determining the effect of other factors. 2D geometry is the main … WebOct 23, 2012 · There is no rule chiseled in stone, but you may consider the following ratios between size tolerance and associated form tolerance (flatness or straightness) in relation to level of precision: Normal (or “standard” or “medium”): 60%. Enhanced (or “reduced tolerance”, or “fine”): 40%. High (or “precision” or “extra fine ...
WebSep 1, 1999 · Four torque converters with different flatness ratios were manufactured and tested in order to evaluate the change in their overall performance, including efficiency, stall torque ratio and torque transmission capacity. The experimental results show that the overall performance deteriorates when the flatness ratio is reduced to less than about 0.2.
