The customer-centric model was developed by Dean Wilde and Arnoldo Hax. The model was first thought about at a confab of alumni that took place at Massachusetts Institute of Technology . [5] The development of the delta model created a large amount of research into the drivers of sustainable profitability for businesses. [6]

Moving heat source in on a thin plate. In heat transfer, moving heat sources is an engineering problems, particularly in welding. In the early 20th century, welding engineers began studying moving heat sources in thin plates, both empirically and theoretically. [1] Depending on welding parameters, plate geometry and material properties, the ...
Turbulence modeling. A simulation of a physical wind tunnel airplane model. In fluid dynamics, turbulence modeling is the construction and use of a mathematical model to predict the effects of turbulence. Turbulent flows are commonplace in most real-life scenarios. In spite of decades of research, there is no analytical theory to predict the ...
Proportional hazards model. Proportional hazards models are a class of survival models in statistics. Survival models relate the time that passes, before some event occurs, to one or more covariates that may be associated with that quantity of time. In a proportional hazards model, the unique effect of a unit increase in a covariate is ...
The existence of the thermodynamic limit for the free energy and spin correlations were proved by Ginibre, extending to this case the Griffiths inequality. [3]Using the Griffiths inequality in the formulation of Ginibre, Aizenman and Simon [4] proved that the two point spin correlation of the ferromagnetics XY model in dimension D, coupling J > 0 and inverse temperature β is dominated by (i.e ...
The Rescorla–Wagner model (" R-W ") is a model of classical conditioning, in which learning is conceptualized in terms of associations between conditioned (CS) and unconditioned (US) stimuli. A strong CS-US association means that the CS signals predict the US. One might say that before conditioning, the subject is surprised by the US, but ...
