PPD (percentage of people dissatisfiedThermal comfortUncertainty budgetFanger's predicted mean vote (PMV) equation is the result of the combined quantitative effects of the air temperature, mean radiant temperature, air velocity, humidity activity level and clothing thermal resistance. PMV is a ...
Provides a tool box that can be used to develop either pre-defined or user defined curve fits for any data contained in an EES table. Includes the ability to weight the data using uncertainty information.Watch this YouTube short Equations Window Tabs The equations in your EES program can now...
Uncertainty σ Se The linear model is the basic assumption required for statistical inference in regression and correlation analysis. Confidence intervals and hypothesis tests based on the slope coefficient will assume that the linear model holds in the population. In particular, these confidence interval...
Elbro8 demonstrated, using a simple definition for the free-volume (Eq. 13), that the FV percentages of solvents and polymers are different. In the typical case, the FV percentage of solvents is greater (40-50%) than that of polymers (30-40%). There are two exceptions to this rule;...
Percentage deviation of heat-of-vaporization data from values calculated with the present EOS as a function of temperature Full size image The uncertainty of the present EOS regarding heat of vaporization in the temperature range of 300 K to 340 K is estimated to be 0.8 %. 3.3 Homogeneous Dens...
juncture. Teams responsible for measuring the impact of their efforts and making tough budgeting decisions on that basis must feel as though the floor has fallen out from under them. And in many ways, owing to constantly evolving consumer habits, new market dynamics, and widespread uncertainty, ...
For such a lens, a large percentage of the light will be coherently focused or defocused upon propa- gation beyond the lens. Conversely, a small percentage of the light will be diffusely scattered by the random cloudy inclusions within the glass. In the hard-x-ray analogue of this ...
For example, the effects of the gyroscopic movement, uncertainty of the physical parameters that characterize the system, electrical noise signals and so on. All of these effects are considered as external disturbances for the controller design. 2.2. Stable manifold of the HJB equation The stable ...
Again, using PMMA, it was found that depending on the contact angle liquid used, the percentage of the solid PMMA surface covered with condensate from the liquid drops, varied from 0.06 to 0.07% for glycerol and formamide, to 3.5% for water. The latter percentage for water could also ...
Quinton (2013), in discussing the uncertainty of complex erosion models like EUROSEM and WEPP, suggests that this uncertainty is reason enough to describe the erosion system with simpler models than those that are currently in vogue. One reason for the popularity of USLE-type modelling i...
