Simplified, very simplified.
Our case is a conceptual and simplified paper machine short circulation control design, which involves defining a dynamic design optimization problem with scenarios on dynamic effects external to the process.
A simplified model of the systemic circulation and the pump is used to study the system response to changes in pulmonary vein pressure and to benchmark controller performance.
The developed model is non-stationary and uses a rather simplified model of internal convection (circulation), yet it takes into account all important phenomena and parameters, e.g. the chemical composition of gaseous and liquid phases, gas velocity and drop geometry, drop exposure time, gas absorption and chemical reactions within the drop, and temperature.
The Sunderland and Mason (2007) model uses a simplified physical framework for ocean circulation that approximately matches the limited oceanic Hg data available.
It is thus likely that many of the ideas uncovered here were not restricted only to those who practised medicine and midwifery, but had a wider circulation, however generalized and simplified for the non-specialist.
A simplified diagram of the Atlantic Meridional Overturning Circulation.
A recent study investigated the atmospheric dynamics of a gas giant orbiting a binary star using longitudinally averaged energy balance models (LEBM) as well as a general circulation models (GCM) using a simplified dynamical model for the motion of the planet around the double star12.
The classical Welander oscillatory natural circulation problem, which resembles a simplified example for many types of natural circulation loops widely seen in nuclear reactor systems, was chosen to illustrate the applicability of such methods in system analysis codes, and to demonstrate the advantages of such methods over the low-order methods widely used in existing system analysis codes.
Therefore, the human circulation can be reasonably described by using the simplified Windkessel model, in which a capacitive element (total arterial compliance) is added to SVR.
Explorations of these uncertainties have so far relied on scaling approaches3,4, large ensembles of simplified climate models1,2, or small ensembles of complex coupled atmosphere ocean general circulation models5,6 which under-represent uncertainties in key climate system properties derived from independent sources7,8,9.
