Notes on the Optimum Chemical Balance Weighing Design
Ceranka, Bronisław; Graczyk, Małgorzata (Wydawnictwo Uniwersytetu Łódzkiego, 2012)In the paper, the model of the chemical balance weighing design, i.e. model in that the result of experiment we can describe as linear function of unknown measurements of objects with known factors, is presented. ... -
Some Construction of Regular A-Optimal Spring Balance Weighing Designs for Even Number of Objects
Graczyk, Małgorzata (Wydawnictwo Uniwersytetu Łódzkiego, 2012)In the paper, the problem of construction of the spring balance weighing designs satisfying the criterion of A-optimality is discussed. The incidence matrices of the partially incomplete block designs are used for ...
