Combined Intra- and Inter- Block Analysis of Balanced Ternary Designs [PDF]
In the present paper an attempt has been made to study the inter–and intra-block estimation of treatment effects contrasts with random block effects in the context of balanced ternary designs. The analysis is illustrated through examples.

New Results Regarding the Construction Method for D‑optimal Chemical Balance Weighing Designs
We study an experiment in which we determine unknown measurements of p objects in n weighing operations according to the model of the chemical balance weighing design. We determine a design which is D‑optimal. For the construction of the D‑optimal design,

About Some Properties and Constructions of Experimental Designs
In this paper, we consider the problems related to the determining plan of the experiment performed according to the model of the chemical balance weighing design under additional assumption that the experimental errors are equally negatively correlated.

The number of repeated blocks in balanced ternary designs with block size three II
The following statement is proved: a balanced ternary design on \(v\) elements with block size three, index two, and each element repeated in precisely two blocks, and having exactly \(k\) pairs of repeated blocks exists if and only if \(v\equiv 0,2\pmod 3\), \(v\geq 5\), \(0\leq k\leq v(v- 5)/6\), and \(k\neq v(v-5)/6-1\).

A family of balanced ternary designs with block size four [PDF]
This paper shows the existence of an infinite family of cyclic balanced ternary designs where the block size is 4, the index 2 and each block contains precisely one repeated element.

More balanced ternary designs with block size three
AbstractA balanced ternary design (BTD) is a balanced design on V elements with constant block size, in which each element may occur 0, 1 or 2 times in each block. Thus blocks may be collections of elements rather than subsets of elements. A regular BTD is one in which each element occurs singly in ϱ1 blocks, and is repeated in ϱ2 blocks. The condition

Balanced ternary designs with block size three, any Λ and anyR
A balanced ternary design with V elements is a collection of B blocks (which are multisets) of size K such that each element occurs 0, 1 or 2 times per block and R times altogether, and such that each unordered pair of distinct elements occur \(\Lambda\) times.

ON D-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS
The paper deals with the problem of determining the chemical balance weighing designs satisfying the criterion of D-optimality under assumption that the measurement errors are equal correlated and they have the same variances.

CONSTRUCTION METHOD OF A-OPTIMAL CHEMICAL BALANCE WEIGHING DESIGNS
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 ...
