A Concept Analysis of Uncertainty in Epilepsy

open access: yesJournal of Korean Academy of Nursing, 2017
This concept analysis was done to clarify 'uncertainty in epilepsy'.Walker and Avant's methodology guided the analysis. In addition, the concept was compared with uncertainty in other health problems.'Uncertainty in epilepsy' was defined as being in the condition as seen from the epilepsy experience where cues were difficult to understand because they ...

Uncertainty analysis [PDF]

open access: yes, 1982
An evaluation is made of the suitability of analytical and statistical sampling methods for making uncertainty analyses. The adjoint method is found to be well-suited for obtaining sensitivity coefficients for computer programs involving large numbers of equations and input parameters. For this purpose the Latin Hypercube Sampling method is found to be

Short-term wind power prediction and uncertainty analysis based on VDM-TCN and EM-GMM

open access: yesFrontiers in Energy Research
Due to the fluctuating and intermittent nature of wind energy, its prediction is uncertain. Hence, this paper suggests a method for predicting wind power in the short term and analyzing uncertainty using the VDM-TCN approach.

Sub-Pixel Extraction of Laser Stripe Center Using an Improved Gray-Gravity Method †

open access: yesSensors, 2017
Laser stripe center extraction is a key step for the profile measurement of line structured light sensors (LSLS). To accurately obtain the center coordinates at sub-pixel level, an improved gray-gravity method (IGGM) was proposed.

Interval Energy Flow Analysis in Integrated Electrical and Natural-Gas Systems Considering Uncertainties

open access: yesEnergies, 2019
As integrated electrical and natural-gas systems (IENGS) are popularized, the uncertainties brought by variation of electrical load, power generation, and gas load should not be ignored.
