In statistics, multivariate adaptive regression splines (MARS) is a form of regression analysis introduced by Jerome H. Friedman in 1991. [1] It is a non-parametric regression technique and can be seen as an extension of linear models that automatically models nonlinearities and interactions between variables.
The new FV3-based model replaced the older latitude-longitude dynamical core (Legacy Mars GCM). Other improvements has been made in order to allow public access to older and newer models of Mars' general circulation. MCMC has recently presented a community analysis pipeline (CAP) which is an open-source tool for analyzing and visualizing the ...
System properties are defined in terms of the behavior. The system = (,,) is said to be "linear" if is a vector space and is a linear subspace of , "time-invariant" if the time set consists of the real or natural numbers and
Orbit modeling is the process of creating mathematical models to simulate motion of a massive body as it moves in orbit around another massive body due to gravity.Other forces such as gravitational attraction from tertiary bodies, air resistance, solar pressure, or thrust from a propulsion system are typically modeled as secondary effects.
The Information-Motivation-Behavioral Skills (IMB) model is a theoretical framework developed by Jeffrey D. Fisher and William A. Fisher in 1992. [1] Initially designed to understand and promote HIV -preventive behaviors, the IMB model has since been applied to various health-related behaviors and interventions.
The idea of transforming Mars into a world more hospitable to human habitation is a regular feature of science fiction. Scientists are now proposing a new approach to warm up Earth's planetary ...
These models expand upon the cold, dry Mars model by envisioning mechanisms whereby subsurface aquifers providing groundwater might be recharged in early Mars history. They thus require a sustained water cycle of some sort on the long term in the Noachian, but do not explicitly require that this water be liquid or fall as precipitation. This ...
