MODELING MODELING [PDF]

open access: yesJournal of the Experimental Analysis of Behavior, 1999
Models are tools; they need to fit both the hand and the task. Presence or absence of a feature such as a pacemaker or a cascade is not in itself good. Or bad. Criteria for model evaluation involve benefit‐cost ratios, with the numerator a function of the range of phenomena explained, goodness of fit, consistency with other nearby models, and ...

Thermodynamic insight into stimuli-responsive behaviour of soft porous crystals

open access: yesNature Communications, 2018
Knowledge of the thermodynamic potential is crucial to characterize the macroscopic state of soft porous crystals. Here, the authors present a generalized thermodynamic approach to construct the Helmholtz free energy and identify the conditions under ...

Seasonality and heterogeneity of malaria transmission determine success of interventions in high-endemic settings: a modeling study

open access: yesBMC Infectious Diseases, 2018
Background Malaria transmission is both seasonal and heterogeneous, and mathematical models that seek to predict the effects of possible intervention strategies should accurately capture realistic seasonality of vector abundance, seasonal dynamics of ...

Sub-national levels and trends in contraceptive prevalence, unmet need, and demand for family planning in Nigeria with survey uncertainty

open access: yesBMC Public Health, 2019
Background Ambitious global goals have been established to provide universal access to affordable modern contraceptive methods. To measure progress toward such goals in populous countries like Nigeria, it’s essential to characterize the current levels ...

High-resolution Model for Seasonal Prediction of Surface Shortwave Radiation in China

open access: yes应用气象学报, 2022
Based on the global high-resolution climate model CAMS-CSM developed by Chinese Academy of Meteorological Sciences, the seasonal prediction skill of downward short-wave radiation flux (DSWRF) in China and three key regions is evaluated during the period ...

To model or not to model?

open access: yesMolecular Biology of the Cell, 2011
In theory, the combination of mathematical modeling with experimental studies can be a powerful and compelling approach to understanding cell biology. In practice, choosing appropriate problems, identifying willing and able collaborators, and publishing the resulting research can be remarkably challenging.

Modeling Modeling

open access: yes, 2009
Model-driven engineering and model-based approaches have permeated all branches of software engineering; to the point that it seems that we are using models, as Molière's Monsieur Jourdain was using prose, without knowing it. At the heart of modeling, there is a relation that we establish to represent something by something else.

Direct and inverse problems for nonlocal heat equation with boundary conditions of periodic type

open access: yesBoundary Value Problems, 2022
A mathematical model of the process of heat diffusion in a closed metal wire is considered. This wire is wrapped around a thin sheet of insulation material. We assume that the insulation is slightly permeable.
