New classes of D-optimal chemical balance weighing designs with correlated errors

Biometrical Letters
Summary This study presents several results concerning the determination of chemical balance weighing designs that satisfy the criterion of D-optimality.

A study of the efficiency of chemical balance weighing designs

Biometrical Letters
Some elements concerning the problem of determining chemical balance designs are considered. A method is presented for determining the best design in classes where no D-optimal design exists.

Measurement of bulk density using the Archimedes method with an inductive spring balance

Metrology and Measurement Systems
The article presents a new version of the hydrostatic method for determining bulk density. A spring balance was designed and constructed for measuring the bulk density of porous samples using the liquid displacement method (Archimedes’ principle). In the
