In this research, for efficient uncertainty management in POF models, a powerful Bayesian framework is proposed. Bayesian approach provides many practical features such as a fair coverage of uncertainty and the updating concept that provide a powerful means for knowledge management, meaning that the ...
Various entropies exist for measuring the uncertainty of basic probability assignment (BPA) in evidence theory. However, from the standpoint of the requirements of uncertainty measurement and physics, these entropies are controversial. Therefore, the process for measuring BPA uncertainty currently remains...
While, historically, in classical thermodynamics, entropy was introduced as a conceptual, deterministic and rather obscure notion, later, within statistical thermophysics, entropy has been given a more rigid probabilistic meaning by Boltzmann and Gibbs, while Shannon used an essentially similar, albeit mo...
What is the meaning of divergence in physics? Give an example. Suppose that you have a circle with a radius of 4.02 \times 10^{0.39} m, what is the calculated uncertainty in the area? Why do we use the standard deviation as a measure of the uncertainty in single timin...
The uncertainty relation has a somewhat different meaning for the energy E and the time t, ∆E∆t≳ ℏ. If the system is in a stationary state, that is, a state that does not change in the absence of external forces, then it follows from the uncertainty relation that the energy...

Physics. the principle of quantum mechanics, formulated by Heisenberg, that the accurate measurement of one of two related, observable quantities, as position and momentum or energy and time, produces uncertainties in the measurement of the other, such that the product of the uncertainties of both...
There are other uncertainties involved, however: some relate to ambiguity and imprecision of meaning; some relate to lack of clarity in the objectives ... French,Simon - 《Journal of the Operational Research Society》 被引量: 224发表: 1995年 Relating error bounds for maximum concentration estimate...
Certainty was a postulate from the earliest times in such fields as logic, mathematics, and physics. In the late nineteenth century, the work of Frege and others cast doubts on logical certainty. In the nineteen-thirties, Gödel called mathematical certainty into question for all but the ...
still rely on Eq. (28) to obtain a consistent uncertainty decomposition where each component directly reflects the propagation of the uncertainty in the corresponding source. In this way, uncertainty components preserve a universal meaning, regardless of the statistical method used for a given ...
