By combining the language of groups with that of geometry and linear algebra, Marius Sophus Lie created one of math’s most ...

This package contains a complete framework based on canonical vine copulas for modeling multivariate data that are partly discrete and partly continuous. The resulting multivariate distributions are ...

Discrete structures are omnipresent in mathematics, computer science, statistical physics, optimisation and models of natural phenomena. For instance, complex random graphs serve as a model for social ...

Abstract: The concept of continuous-aperture multiple-input multiple-output (CAP-MIMO) technology has been proposed recently, which aims at achieving high spectrum efficiency by deploying extremely ...

A lot of surveys are administered via the web. Researchers and practitioners may use discrete rating scales such as Likert-type scales (where respondents click one of radio buttons) or continuous ...

Discrete time is a concept used in various fields, including mathematics, physics, engineering, economics, and finance, to model processes or phenomena that evolve in distinct, separate intervals or ...

Chemical engineering is partially about taking things apart to separate desirable products from undesirable products, and partially about putting things together to make new substances. These are ...
