A Transition Closure Model for Predicting Transition Onset

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">A unified approach which makes it possible to determine the extent and onset of transition in one calculation is presented. It treats the laminar fluctuations in a manner similar to that used in describing turbulence. As a result, the complete flowfield can be calculated using existing CFD codes and without the use

Modeling Democratic Transitions

2016
This chapter examines why some democratic transitions were driven by mass mobilization, while others appeared to be predominantly elite processes, with a greater role for international influences as well. It first outlines core theoretical arguments about the way authoritarian regimes and the capacity for collective action influence transitions to ...

Semiparametric transition rate models

2019
The most widely applied semiparametric model is the proportional hazards model proposed by D. R. Cox, or, as stated in the literature, the Cox model. The Cox model has been used widely, although the proportionality assumption restricts its range of possible empirical applications. This chapter explains the partial likelihood estimation of the model. It

Transition Model

2011
Peak oil and climate change are two of greatest challenges facing humanity at the beginning of 21st century. They are urging humanity to re-think and consider changing on many personal, social, ecological, and economic fronts. Transition and resilience are key concepts initiating this change to prepare communities to forthcoming challenging times ...

Modeling Economic Transition

Journal of Policy Modeling, 1998
Abstract This paper presents a computable general equilibrium model with a two-tier price system incorporated. The model allows for analyzing reform policies in relation to plan prices and quantities. It captures the income effects generated from divergence between market and plan prices.

Transition Modeling in FLOWer — Transition Prescription and Prediction

2006
This paper summarizes the developments of transition prescription and transition prediction techniques which were implemented into the DLR Reynolds-averaged Navier-Stokes (RANS) solver FLOWer in the framework of the DLR projects MEGAFLOW and MEGAFLOW II and the German research project MEGAFLOW.

Anderson transition and nonlinear σ-model

Physics Reports, 1983
The talk covers the behaviour of a quantum mechanic particle moving in a random potential with special emphasis on the critical behaviour near the mobility edge. Symmetry arguments are reviewed which allow the mapping of such a system onto a field theoretical model of interacting matrices. This model yields an expansion of the critical exponents at the
