General Circulation Models (GCM)

Created Dec 22, 2021 (15:02) by Unknown User (Sydney Eiss)

"Numerical models (General Circulation Models or GCMs), representing physical processes in the atmosphere, ocean, cryosphere and land surface, are the most advanced tools currently available for simulating the response of the global climate system to increasing greenhouse gas concentrations" (IPCC 2020; web) [Retrieved from https://ipcc-data.org/guidelines/pages/gcm_guide.html]

General Equilibrium Theory

Created Dec 22, 2021 (15:02) by Unknown User (Helen Gardner)

The theory describing, the state of the economic system at any point of time as the solution of a system of simultaneous equations representing the demand for goods by consumers, the supply of goods by producers, and the equilibrium condition that supply equal demand on every market. (Arrow and Debreu (1954) [Arrow, K. J., & Debreu, G. (1954). Existence of an equilibrium for a competitive economy. Econometrica: Journal of the Econometric Society, 265-290.]

General Tsunami Hazard Maps

Created Dec 22, 2021 (15:02) by Unknown User (Sydney Eiss)

A map that shows inundation values of a simulated tsunami over a geographic area

Generic Scenario of Tornado Events

Created Dec 22, 2021 (15:02) by Unknown User (McAlister Kosar)

Tornado Hazard. In IN-CORE, four simplified scenarios for tornado wind speed distributed spatially over a region or community are available. All tornado width and length data will come from the statistics developed by Standohar-Alfano and van de Lindt (2015) for NWS data between 1973-2011. The four alternatives for distribution of tornado intensity along width and length range from the simplest and most conservative to a more realistic, but still idealized, spatial distribution. However, it is underscored that these are idealizations and that tornado wind speeds are highly turbulent, but since they have not yet been accurately measured by scientists, this idealization is necessary. Please see the tornado hazard model page on Confluence with more details. https://opensource.ncsa.illinois.edu/confluence/display/INCORE1/Tornado+Hazard+Model

Genetic Algorithms

Created Dec 22, 2021 (15:02) by Jong Lee

A genetic algorithm is an optimization algorithm belonging to the class of nature-inspired metaheuristics. Genetic algorithms are population-based stochastic meta-heuristic algorithms inspired by genetic evolution consisting of different operations such as crossover, mutation, selection, etc. (Goldberg 1989)

GIS Data

Created Dec 22, 2021 (15:02) by Unknown User (Anonymous User)

Geography A geographic information system (GIS) is a system designed to capture, store, manipulate, analyze, manage, and present all types of geographical data. GIS provides spatial data and often 'attribute data' that provides more information about spatial location. (Martindale 2019; web) [Martindale, J. (2019). Research Guides: Mapping and Geographic Information Systems (GIS): What is GIS? Retrieved from: https://researchguides.library.wisc.edu/c.php?g=178144&p=1169699]

Global Building Taxonomy

Created Dec 22, 2021 (15:02) by Jong Lee

A common terminology of different building designs and construction practices around the world. Often used in earthquake modeling, such as the Global Earthquake Model (GEM). (Brzev et al. 2012)

Goodness of Fit Metrics

Created Dec 22, 2021 (15:02) by Unknown User (Sydney Eiss)

A statistical method to describe how well it fits into a set of observations. Goodness of fit indices summarize the discrepancy between the observed values and the values expected under a statistical model. (Maydeu-Olivares and Garcia-Forero, 2010) https://doi.org/10.1016/B978-0-08-044894-7.01333-6

Google Street View

Created Dec 22, 2021 (15:02) by Jong Lee

Google street view provides a street-level snapshot of a particular place and can be used to virtually audit the built environment. (Mabon 2016)

granularities

Created Dec 22, 2021 (15:02) by Jong Lee

Synonym(s):
  • General
The scale or level of detail present in set of data or other phenomenon. Granularity can be used to describe the size and information content of model elements as well as the nature of relationships between model elements. Granularity can also relate to the resolution of output obtained through analysis based on a model.

ground failures

Created Dec 22, 2021 (15:02) by Jong Lee

Synonym(s):
  • Geology
"A general reference to landslides, liquefaction, lateral spreads, and any other consequence of shaking that affects the stability of the ground." (USGS Earthquake, web)
