The V-model is a graphical representation of a systems development lifecycle.It is used to produce rigorous development lifecycle models and project management models. The V-model falls into three broad categories, the German V-Modell, a general testing model, and the US government standard.
The V-Model reflects a project management view of software development and fits the needs of project managers, accountants and lawyers rather than software developers or users. Although it is easily understood by novices, that early understanding is useful only if the novice goes on to acquire a deeper understanding of the development process ...
A common use of the phrase "ANN model" is really the definition of a class of such functions (where members of the class are obtained by varying parameters, connection weights, or specifics of the architecture such as the number of neurons, number of layers or their connectivity).
In biology, strategies are genetically inherited traits that control an individual's action, analogous with computer programs. The success of a strategy is determined by how good the strategy is in the presence of competing strategies (including itself), and of the frequency with which those strategies are used. [ 9 ]
The UNTB model produces a dimensionless "fundamental biodiversity" number, θ, which is derived using the formula: θ = 2J m v. where: J m is the size of the metacommunity (the outside source of immigrants to the local community) v is the speciation rate in the model
The infinitesimal model, also known as the polygenic model, is a widely used statistical model in quantitative genetics and in genome-wide association studies.Originally developed in 1918 by Ronald Fisher, it is based on the idea that variation in a quantitative trait is influenced by an infinitely large number of genes, each of which makes an infinitely small (infinitesimal) contribution to ...
The algorithm of Figure 2 is a basic example of what is called an equation-free model. [20] When mutations are enabled in the microscale model (>), the population grows more rapidly than in the macroscale model (Figures 3C and 3D). Mutations in parameters allow some individuals to have higher birth rates and others to have lower death rates ...
The narrow escape problem is a ubiquitous problem in biology, biophysics and cellular biology which has the following formulation: a Brownian particle (ion, molecule, or protein) is confined to a bounded domain (a compartment or a cell) by a reflecting boundary, except for a small window through which it can escape. The narrow escape problem is ...
