From Interval Computations to Constraint-Related Set Computations: Towards Faster Estimation of Statistics and ODEs under Interv
Interval computations estimate the uncertainty of the result of data processing in situations in which we only know the upper bounds ∆ on the measurement errors. In this case, ba...

Equations resolving a conjecture of Rado on partition regularity
A linear equation L is called k-regular if every k-coloring of the positive integers contains a monochromatic solution to L. Richard Rado conjectured that for every positive intege...

A kinematic model of continuous separation and classification of polydisperse suspensions
Kinematic models for polydisperse suspensions are based on specifying the solid-fluid relative velocity for each solids species as a function of the local solids concentrations. On...
