Non-parametric data-driven approach to reliability-based topology optimization of trusses under uncertainty of material constitutive law

open access: yesJournal of Advanced Mechanical Design, Systems, and Manufacturing
The material behavior intrinsically possesses the aleatory uncertainty (i.e., the natural variability). Against uncertainty in a given data set of elastic material responses, this paper presents a data-driven approach to reliability-based truss topology ...

Uncertainty impact of isotherm models on liquid-phase adsorption thermodynamics: A bayesian inference perspective

open access: yesCleaner Chemical Engineering
Liquid-phase adsorption, a fundamental process where molecules in a liquid medium adhere to a solid surface, plays a crucial role in various chemical engineering applications such as wastewater decontamination and solvent recovery. These phenomena can be

Stochastic forecast of the population of Poland, 2005-2050 [PDF]

open access: yes
Forecasting the population of Poland is very challenging. Firstly, the country has been undergoing rapid demographic changes. In the 1990s, they were influenced by the political, economic, and social consequences of the collapse of the communist regime ...

Asteroid orbital error analysis: Theory and application [PDF]

open access: yes
We present a rigorous Bayesian theory for asteroid orbital error estimation in which the probability density of the orbital elements is derived from the noise statistics of the observations.

Characterization of uncertainty in shield tunneling excavated in soft soils based on gap parameter

open access: yesYantu gongcheng xuebao
To prevent the risk of displacement induced by shield tunneling, it is necessary to conduct probabilistic analysis. Gap parameter explains the source of ground loss in detail by dividing the ground loss into three parts.

Sequential measurements of non-commuting observables with quantum controlled interactions

open access: yesNew Journal of Physics, 2014
The origin of non-classical correlations is difficult to identify since the uncertainty principle requires that information obtained about one observable invariably results in the disturbance of any other non-commuting observable.

Conditional Versus Non-Conditional Probabilities in Quantum Bound States and their Relationship to the Heisenberg Uncertainty Principle and Statistical Mechanics

open access: yes, 2019
Recently, there have been a number of papers in the literature dealing with the calculation of Sp + Sx for quantum bound states. Here Sp is the momentum Shannon entropy -Sum 2fp*fp ln(fp) and Sx the position Shannon entropy -Sum 2 W(x)W(x) ln[W(x)] where W(x) is the wavefunction.

Experimental transition probabilities and oscillator strengths of singly ionised Xenon (Xe II) in the ultraviolet. A fully statistical approach to the determination of uncertainties

open access: yesSpectrochimica Acta Part B: Atomic Spectroscopy
We report 92 experimental values of transition probabilities and oscillator strengths for singly ionised xenon (Xe II) in the ultraviolet region (217–385 nm), 91 of which have been measured for the first time. The transition probabilities were obtained from the analysis of spectra emitted by a plasma in partial local thermodynamic equilibrium (pLTE ...

Joint Bayesian Stochastic Inversion of Well Logs and Seismic Data for Volumetric Uncertainty Analysis [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2015
Here in, an application of a new seismic inversion algorithm in one of Iran’s oilfields is described. Stochastic (geostatistical) seismic inversion, as a complementary method to deterministic inversion, is perceived as contribution combination of ...

Australia's uncertain demographic future [PDF]

open access: yes
The techniques of probabilistic population forecasting are increasingly being recognised as a profitable means of overcoming many of the limitations of conventional deterministic variant population forecasts.
