A Regular D‑optimal Weighing Design with Negative Correlations of Errors
(Wydawnictwo Uniwersytetu Łódzkiego, 2019-09-30)
The issues concerning optimal estimation of unknown parameters in the model of chemical balance weighing designs with negative correlated errors are considered. The necessary and sufficient conditions determining the regular ...
A Highly D‑efficient Spring Balance Weighing Design for an Even Number of Objects
(Wydawnictwo Uniwersytetu Łódzkiego, 2019-09-30)
The problem of determining unknown measurements of objects in the model of spring balance weighing designs is presented. These designs are considered under the assumption that experimental errors are uncorrelated and that ...
