Poisson's ratio n (General Physics) a measure of the elastic properties of a material expressed as the ratio of the fractional contraction in breadth to the fractional increase in length when the material is stretched. Symbol:μorν Collins English Dictionary – Complete and Unabridged, 12th Edit...
n (for S. Poisson; symbol μ or ν) In a material under tensile stress, the ratio of the transverse contraction to the longitudinal elongation. For metals, Poisson's ratio is bout 0.3, for concrete,...Jan W. GoochSpringer New York...
a Non-reciprocal Poisson’s ratio. “FEA (finite-element analysis),”“Exp. (experiment),”“Eqv. (equivalent),” and “Eff. (effective)” correspond to simulations of designed unit cells, experiments about designed unit cells, simulations of equivalent models, and effective material parameters,...
a Top and side view for wz monolayer, in which we denote three structural parameters, i.e., the sides and angle of adjacently stacked triangles r1/r2 and θ, and the layer height ∆h, here the symbol S denotes the area of the triangle. b Schematic representation for the occurrence of...
The study suggests that GWR enhances the overall performance of flood models and could potentially outperform traditional methods such as non-spatial logistic regression and frequency ratio in identifying areas at risk of flooding. In their study, Chang and Su (2007) focus on establishing a ...
As an example, by assuming Rayleigh fading for point-to-point channel in the network, the cumulative distribution function (CDF) of the signal-to-noise and interference ratio (SINR) for the test receiver in the network can be calculated as follows [11], (21.3)FSINR(θ)=P{SINR≤θ}=P{...
glmGamPoiprovides an interface to do quasi-likelihood ratio testing to identify differentially expressed genes. To demonstrate this feature, we will use the data fromKanget al.(2018)provided by theMuscDatapackage. This is a single cell dataset of 8 Lupus patients for which 10x droplet-based scR...
This is a speed ratio of three orders of magnitude. The PIC method requires that particles travel less than a cell length per time step. As such, the simulation time step will be determined by the fastest species. Hence, if want to include electrons, we need to run the simulation at ...
The statistical significance of the term t is evaluated by the standard likelihood ratio test [37]. The null hypothesis is that t is not relevant to any gene, which is equivalent to say, θ = 0; and the alternative hypothesis is θ > 0. The test statistic is expressed as: (5) wher...
11), and the vertical displacement is converted to nominal strain by taking its ratio to the initial height of the sandwich panel (as the symbol “H” shown in Fig. 11). Nominal stress – strain curves of the void honeycombs are shown in Fig. 12. As expected, the compressive procedures...
