Demographic Transition: A Forcing Model [PDF]
Demography, 1974 Abstract Transition Theory provides the theoretical underpinning for many explanations for past population changes and, more importantly, for many population projections. Our paper proves, through the use of symbolic logic, that Transition Theory does not contain principles strong enough to support population projections.

Interactions of fast ions with graphene [PDF]
Hemijska Industrija, 2009 In this work, we study the interactions of fast ions with graphene describing the excitations of the electron gas in graphene by a two-dimensional (2D) hydrodynamic model (one-fluid and two-fluid model).

Image Force Corrections to Tung's Inhomogeneous Schottky Barrier Model
, 2021 The popular Tung model for Schottky barrier inhomogeneity considers how low-barrier patches (embedded in a high barrier background) impact the diode current. However, Tung's model fails to account for the image-force effect.

On oscillations in the Social Force Model [PDF]
Physica A: Statistical Mechanics and its Applications, 2015 The Social Force Model is one of the most prominent models of pedestrian dynamics. As such naturally much discussion and criticism has spawned around it, some of which concerns the existence of oscillations in the movement of pedestrians. This contribution is investigating under which circumstances, parameter choices, and model variants oscillations do

Model for Paradigmatic Projection of Military Force [PDF]
Bezbednosni Dijalozi, 2015 The new security threats and particularly the conflict in Ukraine have announced a new phase of re-shaping of the global security scene. Questions that were unthinkable until recently are now urgent as they refer to possible escalation and ...

Iterative methods for the force-based quasicontinuum approximation : analysis of a 1D model problem [PDF]
, 2011 Force-based atomistic-continuum hybrid methods are the only known pointwise consistent methods for coupling a general atomistic model to a finite-element continuum model.

Cutting Force Transition Model Considering the Influence of Tool System by Using Standard Test Table
Sensors, 2021 The cutting force prediction model usually uses the classical oblique transformation method, which introduces the orthogonal cutting parameters into the oblique milling edge shape, and combines the geometric parameters of the tool to convert the ...

Multiplicative Latent Force Models [PDF]
, 2019 Bayesian modelling of dynamic systems must achieve a compromise between providing a complete mechanistic specification of the process while retaining the flexibility to handle those situations in which data is sparse relative to model complexity, or a full specification is hard to motivate.
