Static vs. dynamic. A dynamic model accounts for time-dependent changes in the state of the system, while a static (or steady-state) model calculates the system in equilibrium, and thus is time-invariant. Dynamic models typically are represented by differential equations or difference equations. Explicit vs. implicit.
CGE modelling of richer economies descends from Leif Johansen's 1960 [4] MSG model of Norway, and the static model developed by the Cambridge Growth Project [5] in the UK. Both models were pragmatic in flavour, and traced variables through time. The Australian MONASH model [6] is a modern representative of this class. Perhaps the first CGE ...
The Hammerstein-Wiener model consists of a linear dynamic block sandwiched between two static nonlinear blocks. [10] The Urysohn model [11] [12] is different from other block models, it does not consists of sequence linear and nonlinear blocks, but describes both dynamic and static nonlinearities in the expression of the kernel of an operator.

System dynamics is a methodology and mathematical modeling technique to frame, understand, and discuss complex issues and problems. Originally developed in the 1950s to help corporate managers improve their understanding of industrial processes, SD is currently being used throughout the public and private sector for policy analysis and design.
The first applications of computer simulations for dynamic systems was in the aerospace industry. [5] Commercial uses of dynamic simulation are many and range from nuclear power, steam turbines, 6 degrees of freedom vehicle modeling, electric motors, econometric models, biological systems, robot arms, mass-spring-damper systems, hydraulic systems, and drug dose migration through the human body ...
Dynamicism, also termed the dynamic hypothesis or the dynamic hypothesis in cognitive science or dynamic cognition, is a new approach in cognitive science exemplified by the work of philosopher Tim van Gelder. It argues that differential equations are more suited to modelling cognition than more traditional computer models.
Dynamic Bayesian Network composed by 3 variables. Bayesian Network developed on 3 time steps. Simplified Dynamic Bayesian Network. All the variables do not need to be duplicated in the graphical model, but they are dynamic, too. A dynamic Bayesian network (DBN) is a Bayesian network (BN) which relates variables to each other over adjacent time ...
Dynamic systems, unlike static ones, involve temporal changes. Differences in learned representations over time in a dynamic system can arise from actual changes or arbitrary alterations that do not affect the metrics in the latent space with the former reflecting on the system's stability and the latter linked to the alignment of embeddings.
