nietuniforme

Nietuniforme is a term used in several languages, notably Dutch and related linguistic traditions, to describe something that is not uniform. The word combines niet ('not') with uniforme ('uniform'), and in technical contexts it is used as an adjective to characterize variations in density, spacing, or intensity across a domain.

In mathematics and the applied sciences, nietuniforme describes non-uniformity in a system. For example, a nietuniforme grid or mesh has cells of differing size rather than equal spacing, which is common in adaptive numerical methods that allocate resources where the solution changes rapidly. In probability and statistics, a nietuniforme distribution refers to a probability distribution whose density is not constant over its support, leading to varying likelihoods across outcomes.

In imaging and signal processing, nietuniforme sampling refers to sampling patterns that do not follow a regular lattice, often used to reduce data while preserving important features. In materials science and ecology, nietuniforme properties describe heterogeneity, such as variable material density or resource distribution within a habitat.

Critically, nietuniforme is a general descriptor rather than a single formal model; precise definitions depend on the field and the chosen measurement. Related terms include non-uniform, heterogeneity, anisotropy, and adaptive methods. See also nonuniform distribution, adaptive mesh refinement, and variable density.
