The Importance of Uncertainty Analysis and Traceable Measurements in Routine Quantitative ⁹⁰Y-PET Molecular Radiotherapy: A Multicenter Experience [PDF]

Pharmaceuticals, 2023
Molecular Radiation Therapy (MRT) is a valid therapeutic option for a wide range of malignancies, such as neuroendocrine tumors and liver cancers. In its practice, it is generally acknowledged that there is a need to evaluate the influence of different ...

Multidimensional Fractionation of Particles

Separations, 2023
The increasing complexity in particle science and technology requires the ability to deal with multidimensional property distributions. We present the theoretical background for multidimensional fractionations by transferring the concepts known from one ...

Quantifying the Reliability and Uncertainty of Satellite, Reanalysis, and Merged Precipitation Products in Hydrological Simulations over the Topographically Diverse Basin in Southwest China

Remote Sensing, 2022
With the continuous emergence of remote sensing technologies and atmospheric models, multi-source precipitation products (MSPs) are increasingly applied in hydrometeorological research, especially in ungauged or data-scarce regions.

Estimating uncertainty of model parameters obtained using numerical optimisation [PDF]

Modeling, Identification and Control, 2019
Obtaining accurate models that can predict the behaviour of dynamic systems is important for a variety of applications. Often, models contain parameters that are difficult to calculate from system descriptions.

Uncertainties in the Seismic Assessment of Historical Masonry Buildings

Applied Sciences, 2021
Seismic assessments of historical masonry buildings are affected by several sources of epistemic uncertainty. These are mainly the material and the modelling parameters and the displacement capacity of the elements.

Quantification of Grassland Biomass and Nitrogen Content through UAV Hyperspectral Imagery—Active Sample Selection for Model Transfer

Drones, 2022
Accurate retrieval of grassland traits is important to support management of pasture production and phenotyping studies. In general, conventional methods used to measure forage yield and quality rely on costly destructive sampling and laboratory analysis,

Analysis, Quantification and Evaluation of Uncertainty

, 2022
S.113-207This chapter describes the various approaches to analyse, quantify and evaluate uncertainty along the phases of the product life cycle. It is based on the previous chapters that introduce a consistent classification of uncertainty and a holistic

Tolerance analysis approach based on the classification of uncertainty (aleatory / epistemic) [PDF]

, 2012
Uncertainty is ubiquitous in tolerance analysis problem. This paper deals with tolerance analysis formulation, more particularly, with the uncertainty which is necessary to take into account into the foundation of this formulation.
