    The model considers transient changes in vegetation composition and structure in response to environmental change and is, therefore, classified as a Dynamic Global Vegetation Model [2] This new version of IBIS has improved representations of land surface physics, plant physiology, canopy phenology, plant functional type (PFT) differences, and carbon allocation.

    Often IBIs are region-specific and require experienced professionals to provide sufficient quality data to correctly assess a score. Because communities naturally vary as do samples collected from a larger population, identifying robust statistics with acceptable variance is an area of active and important research.

  4. Input/output Buffer Information Specification - Wikipedia

    en.wikipedia.org/wiki/Input/output_Buffer...

    The first IBIS model, version 1.0, was aimed at describing CMOS circuits and TTL I/O buffers. As IBIS evolved with the participation of more companies and industry members, an IBIS Open Forum was created to promote the application of IBIS as a simulation tool format and to make sure that a standard exists.

    en.wikipedia.org/wiki/Modelling_biological_systems

    Modelling biological systems is a significant task of systems biology and mathematical biology. [a] Computational systems biology [b] [1] aims to develop and use efficient algorithms, data structures, visualization and communication tools with the goal of computer modelling of biological systems.

    DGVMs generally combine biogeochemistry, biogeography, and disturbance submodels.Disturbance is often limited to wildfires, but in principle could include any of: forest/land management decisions, windthrow, insect damage, ozone damage etc. DGVMs usually "spin up" their simulations from bare ground to equilibrium vegetation (e.g. climax community) to establish realistic initial values for ...

  7. Issue-based information system - Wikipedia

    en.wikipedia.org/wiki/Issue-based_information_system

    The issue-based information system (IBIS) is an argumentation-based approach to clarifying wicked problems—complex, ill-defined problems that involve multiple stakeholders. [1] Diagrammatic visualization using IBIS notation is often called issue mapping. [2]: ix IBIS was invented by Werner Kunz and Horst Rittel in the 1960s. According to Kunz ...

  8. IBIS Interconnect Modeling Specification - Wikipedia

    en.wikipedia.org/wiki/IBIS_Interconnect_Modeling...

    The format and style of ICM are highly similar to the Input Output Buffer Information Specification (IBIS), and both specifications are managed by the same organization, the IBIS Open Forum. Interconnects under ICM may be represented through tabular frequency-dependent RLGC matrices or through S-parameters in separate Touchstone files. ICM ...
