Nonuniforme

Nonuniforme is an Italian adjective meaning not uniform. It is used to describe variations in quantity, density, or property across space or time, indicating a lack of regularity or symmetry. The term appears in many disciplines to denote heterogeneity in a system, process, or measurement.

In mathematics and statistics, nonuniforme refers to distributions or sampling that are not constant over their domain. Examples include nonuniform distributions on an interval, nonuniform grids in numerical methods, and nonuniform probabilities across outcomes.

In numerical analysis and computational science, a nonuniforme mesh or grid places more nodes where the function changes rapidly, improving accuracy and efficiency. Techniques for adapting mesh density rely on error estimators or feature detection to allocate resources nonuniformly.

In physics and engineering, nonuniforme describes materials whose properties vary spatially, such as compositional gradients or layered media, as well as flow, heat, or stress fields that are not spatially uniform. These variations influence model behavior, measurements, and design considerations.

In geography, biology, and other fields, nonuniforme patterns characterize irregular distributions, such as population density, rainfall, or vegetation. Recognizing nonuniformity is essential for modeling, simulation, and interpretation of data.
