Comparison Between some Methods of Tackling the Lack of Experimental Units Needed for Application of Factorial Experiments [PDF]
المجلة العراقية للعلوم الاحصائية, 2011 Most of the time the researcher confronts a decrease in the experimental units required when applying a certain design, this problem appears especially when conducting the factorial experiments which mostly need great numbers of experimental units, to ...

On balanced incomplete block designs with specified weak chromatic number
, 2013 A weak $c$-colouring of a balanced incomplete block design (BIBD) is a colouring of the points of the design with $c$ colours in such a way that no block of the design has all of its vertices receive the same colour.

Decomposition tables for experiments. II. Two--one randomizations [PDF]
, 2010 We investigate structure for pairs of randomizations that do not follow each other in a chain. These are unrandomized-inclusive, independent, coincident or double randomizations.

On the Classification of Splitting (v, u×c, λ) BIBDs
Cybernetics and Information Technologies, 2018 The (v, u×c, λ)-splitting balanced incomplete block designs correspond to c-splitting authentication codes. We classify splitting balanced incomplete block designs with definite parameters.

Group Divisible Codes and Their Application in the Construction of Optimal Constant-Composition Codes of Weight Three [PDF]
, 2008 The concept of group divisible codes, a generalization of group divisible designs with constant block size, is introduced in this paper. This new class of codes is shown to be useful in recursive constructions for constant-weight and constant-composition

Regular A-optimal Spring Balance Weighing Designs
Revstat Statistical Journal, 2012 The problem of indicating an A-optimal spring balance weighing design providing that the measurement errors have different variances and are uncorrelated is considered.

Highly D‑efficient Weighing Design and Its Construction
Acta Universitatis Lodziensis. Folia Oeconomica, 2017 In this paper, some aspects of design optimality on the basis of spring balance weighing designs are considered. The properties of D‑optimal and D‑efficiency designs are studied.

Deterministic Construction of Measurement Matrices Based on Bose Balanced Incomplete Block Designs
IEEE Access, 2018 Compressed sensing is a novel information collection theory. Compared with the Nyquist sampling theorem, compressed sensing can obtain all the information of a signal with very few samples.
