We are trying to get the date of two years from now in Python datetime. We are expecting to get a valid date 2 years from now. And that is giving the following error: ValueError: day is out of range for month CPython versions tested on: ...
The steamline method for the numerical calculation of the mean characteristics of planar flows was previously only employed in the study of frictionless fl... B Hanel,HJ Mascheck - 《Wissenschaftliche Zeitschrift》 被引量: 0发表: 1975年 Controlled reattachment in separated flows: a variational appro...
Solute-solute potential of mean force for non-polar molecules in water A recently proposed extension of the Pratt-Chandler (PC) theory of the hydration of non-polar solutes has been applied to the calculation of solute-solute radial distribution functions, gaa(r)s. The difference between results...
Numerical modeling of water movement in both unsaturated soils and saturated groundwater aquifers is important for water resource management simulations. The development of efficient numerical algorithms for coupling unsaturated and saturated flow has been a long-lasting challenge in hydrologic modeling, espe...
In the blog there is a MFU calculation that seems to be wrong. Fine-tuning completed in ~13.5 hours and below is the training loss plot. Let's calculate the Model Flops Utilization (MFU) for the training run. A100 GPUs perform ~ 3.12e14 FLOPS per seconds (in float32 or bfloat16 ...
While a powerful tool for uncovering the associations between variables observed in data, it cannot easily indicate causation. Regression as a statistical technique should not be confused with the concept of regression to the mean, also known asmean reversion. Joules Garcia / Investopedia Understanding...
Reaching peak carbon emissions and achieving carbon neutrality will mean a broad and profound systemic socio-economic transformation. Based on China's energy and resource endowment, we will advance initiatives to reach peak carbon emissions in a well-planned and phased way in line with the principle...
Based on these observations, a mechanism underlying the anion selectivity is proposed; both ion species are transported across the channel, but the rate for K(+) is smaller than that for Cl(-) because of the attractive interactions between K(+) and residues on the channel wall. This ...
The penalty has been calculated via comparison of bit-error rates (BERs), obtained using numerical integration, both in continuous-and burst-mode operation. Sensitivity penalties for burst-mode operation as a function of the mean avalanche gain are presented. The Gaussian approximation systematically ...
for the fact that it has more terms, while the adjusted R-squared compensates for the addition of variables; it only increases if the new term enhances the model above what would be obtained by probability and decreases when a predictor enhances the model less than what is predicted by ...
