An econophysics approach to analyse uncertainty in financial markets: an application to the Portuguese stock market [PDF]

open access: yes, 2005
In recent years there has been a closer interrelationship between several scientific areas trying to obtain a more realistic and rich explanation of the natural and social phenomena.

Probabilistic treatment of the uncertainty from the finite size of weighted Monte Carlo data

open access: yes, 2018
Parameter estimation in HEP experiments often involves Monte-Carlo simulation to model the experimental response function. A typical application are forward-folding likelihood analyses with re-weighting, or time-consuming minimization schemes with a new ...

Random and free observables saturate the Tsirelson bound for CHSH inequality [PDF]

open access: yes, 2017
Maximal violation of the CHSH-Bell inequality is usually said to be a feature of anticommuting observables. In this work we show that even random observables exhibit near-maximal violations of the CHSH-Bell inequality.

Classification of the State of Manufacturing Process under Indeterminacy

open access: yesMathematics, 2019
In this paper, the diagnosis of the manufacturing process under the indeterminate environment is presented. The similarity measure index was used to find the probability of the in-control and the out-of-control of the process. The average run length (ARL)

The Recursive Form of Error Bounds for RFS State and Observation with Pd<1

open access: yes, 2012
In the target tracking and its engineering applications, recursive state estimation of the target is of fundamental importance. This paper presents a recursive performance bound for dynamic estimation and filtering problem, in the framework of the finite

Approximation and Uncertainty Quantification of Systems with Arbitrary Parameter Distributions using Weighted Leja Interpolation

open access: yesAlgorithms, 2020
Approximation and uncertainty quantification methods based on Lagrange interpolation are typically abandoned in cases where the probability distributions of one or more system parameters are not normal, uniform, or closely related distributions, due to ...

Uncertainty, Probability and Statistics in Research

open access: yes, 2016
Having considered the major components of scientific method in the preceding chapter, it is now time to consider one of the important aspects of science that, in general, is more or less ignored or played down in most expositions on scientific method: uncertainty. It is also one of the topics that Ph.D.

Probabilistic temperature forecasting based on an ensemble AR modification

open access: yes, 2015
To address the uncertainty in outputs of numerical weather prediction (NWP) models, ensembles of forecasts are used. To obtain such an ensemble of forecasts the NWP model is run multiple times, each time with different formulations and/or initial or ...
