Notes on the Regular E-Optimal Spring Balance Weighing Designs with Correlated Errors

open access: yesRevstat Statistical Journal, 2015
The paper deals with the estimation problem of individual weights of objects in Eoptimal spring balance weighing design. It is assumed that errors are equal correlated.

Contribution to spring balance weighing designs

open access: yesBiometrical Letters, 2022
Summary In this paper, we present some new results regarding spring balance weighing designs. We consider issues with regard to conditions for the existence of optimal designs, and give examples of optimal designs.

Optimum Chemical Balance Weighing Design under Certain Condition [PDF]

open access: yes, 2009
2000 Mathematics Subject Classification: 62K05, 05B05.The problem of estimation of unknown weights of p objects is considered. The experiment is carried out according to the standard Gauss-Markoff model of the chemical balance weighing design.

CONSTRUCTION METHOD OF A-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS

open access: yesActa Universitatis Lodziensis. Folia Oeconomica, 2015
Here, we study the design in that we determine unknown measurements of p objects by used of n measurement operations. For that reason we consider the chemical balance weighing design under assumption that the measurement errors are uncorrelated and they ...

SwarMAV: A Swarm of Miniature Aerial Vehicles [PDF]

open access: yes, 2006
As the MAV (Micro or Miniature Aerial Vehicles) field matures, we expect to see that the platform's degree of autonomy, the information exchange, and the coordination with other manned and unmanned actors, will become at least as crucial as its ...

Randomized Fractional Weighing Designs

open access: yesThe Annals of Mathematical Statistics, 1966
Consider the problem of estimating unbiasedly a linear function, $\lambda?' \omega, \omega' = (\omega_1, \cdots, \omega_p)$, of $p$ weights $\omega_1, \cdots, \omega_p (0 < \omega_i < \infty$ for all $i = 1, \cdots, p)$ when the number of possible weighing operations, $n$, is smaller than $p$.

A nonlinearity in permanent-magnet systems used in watt balances

open access: yes, 2014
Watt balances are used to measure the Planck constant and will be used in the future to realize mass at the kilogram level. They increasingly rely on permanent magnet systems to generate the magnetic flux.

Some Optimum Weighing Designs

open access: yesThe Annals of Mathematical Statistics, 1959
Suppose we are given $N$ objects to be weighed in $N$ weighings with a chemical balance having no bias. Let $x_{ij} = 1$ if the $j$th object is placed in the left pan in the $i$th weighing, $= -1$ if the $j$th object is placed in the right pan in the $i$th weighing, $= 0$ if the $j$th object is not weighed in the $i$th weighing. The $N$th order matrix $
