Semi-Empirical Aging Model Development Via Accelerated Aging Test

open access: yes, 2016
Modelling of the degradation mechanisms has a crucial role during the aging analysis, which determines the accuracy of the lifetime estimation. Conventionally, analytical and semi-empirical models are utilized during the aging analysis. Analytical models

Application of Hansen solubility parameters in the eutectic mixtures: difference between empirical and semi-empirical models

open access: yesScientific Reports
Hansen Solubility Parameters (HSPs) are widely used as a tool in solubility studies. Given the variety of existent approaches to predict these parameters, this investigation focused on estimating the HSPs of a set of Natural Deep Eutectic Systems (NADES),

Intensification of Maize-Legume Based Systems in the Semi-Arid Areas of Tanzania

open access: yes, 2019
This dataset is from the research study that aims to diversify the production environment to de-risk production in these semi-arid ecologies. In this study, two approaches were used , i.e.

Duverger, semi-presidentialism and the supposed French archetype [PDF]

open access: yes, 2009
The concept of semi-presidentialism was first operationalised by Maurice Duverger. There are now 17 countries with semi-presidential constitutions in Europe.

On the Use of Semi-empirical Flame Models for Spreading Chaparral Crown Fire

open access: yesFrontiers in Mechanical Engineering, 2019
Flame geometry plays a key role in shaping fire behavior as it can influence flame spread, radiative heat transfer and fire intensity. For wildland fire, thorough characterizations of flame geometry can help advance the derivation of comprehensive models

Accelerated Computation of Free Energy Profile at ab Initio Quantum Mechanical/Molecular Mechanics Accuracy via a Semi-Empirical Reference Potential. II. Recalibrating Semi-Empirical Parameters with Force Matching

open access: yes, 2019
An efficient and accurate reference potential simulation protocol is proposed for producing ab initio quantum mechanical molecular mechanical (AI-QM/MM) quality free energy profiles for chemicalreactions in a solvent or macromolecular environment.

Rigorous Results, Cross-Model Justification, and the Transfer of Empirical Warrant: The Case of Many-Body Models in Physics [PDF]

open access: yes, 2008
This paper argues that a successful philosophical analysis of models and simulations must accommodate an account of mathematically rigorous results. Such rigorous results may be thought of as genuinely model-specific contributions, which can neither be ...

Estimation of Aboveground Biomass in Alpine Forests: A Semi-Empirical Approach Considering Canopy Transparency Derived from Airborne LiDAR Data

open access: yesSensors, 2010
In this study, a semi-empirical model that was originally developed for stem volume estimation is used for aboveground biomass (AGB) estimation of a spruce dominated alpine forest. The reference AGB of the available sample plots is calculated from forest
