Notes on Selected Optimal Weighing Designs

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2021
In this paper, some problems related to the construction of highly D‑efficient spring balance weighing designs are presented. We give some conditions determining the relations between the parameters of such designs and construction examples.

Notes on the Efficiency of Spring Balance Weighing Designs with Correlated Errors for An Even Number of Objects

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2023
In this paper, some issues regarding the efficiency of spring balance weighing designs for a selected class are presented. We give some conditions determining the relations between the parameters of such designs and construction examples.

Selected Remarks on Highly D‑efficient Spring Balance Weighing Designs

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2021
Here, we consider a new construction method of determining highly D-efficient spring balance weighing designs in classes in which a D-optimal design does not exist.

$D$-Optimum Weighing Designs [PDF]

open access: yesThe Annals of Statistics, 1980
For the problem of weighing $k$ objects in $n$ weighings $(n \geq k)$ on a chemical balance, and certain related problems, we obtain new results and list the designs which have been proved $D$-optimum up to this time. While some of these optimality results have been known for some time, others are fairly recent.

Development and design of an affordable field scale weighing lysimeter using a microcontroller system

open access: yesSmart Agricultural Technology, 2023
Weighing lysimeters are used to measure and understand the crop water uptake over time. Weighing lysimeters can estimate crop evapotranspiration by recording the change in weight of a plant, soil, and water.
