Two-Scale Investigation of the Retention Behavior of a Well-Graded Mixed Soil

Geosciences, 2021
The hydraulic characterization of mixed compacted soils is helpful for the design of earthworks subjected to drying–wetting cycles. When the mixed soil is well-graded and made of both coarse and fine fractions, its matric suction may also be due to the ...

On physical modelling of rock

International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1981
The problems of satisfying similarity between a physical model and the prototype in rock wherein fissures and cracks place a role in physical behavior is explored. The need for models of large physical dimensions is explained but also testing of models of the same prototype over a wide range of scales is needed to ascertain the influence of lack of ...

Semantics of Computable Physical Models

Studia Logica, 2023
AbstractThis article reformulates the theory of computable physical models, previously introduced by the author, as a branch of applied model theory in first-order logic. It provides a semantic approach to the philosophy of science that incorporates aspects of operationalism and Popper’s degrees of falsifiability.
