On incomplete and balanced incomplete block designs [PDF]

open access: yesProceedings of the American Mathematical Society, 1963
By an incomplete block design we will mean an arrangement of v different varieties of objects in b distinct blocks or sets such that a block does not contain all the varieties and a variety appears at most once in a block. An incomplete block design which satisfies two extra conditions, viz.

Block Intersections in Balanced Incomplete Block Designs [PDF]

open access: yesCanadian Mathematical Bulletin, 1964
One of the most interesting of the smaller BIBD's is the system (8, 14, 7, 4, 3), where we write the parameters in the standard order v, b, r, k, λ. One representation of a design with these parameters is 1248, 3567; 2358, 1467; 3468, 1257; 4578, 1236; 5618,2347; 6728,1345; 7138,2456.

Complete/incomplete multi‐view subspace clustering via soft block‐diagonal‐induced regulariser

open access: yesIET Computer Vision, 2021
This study proposes a novel multi‐view soft block diagonal representation framework for clustering complete and incomplete multi‐view data. First, given that the multi‐view self‐representation model offers better performance in exploring the intrinsic ...

Classifying the tracing difficulty of 3D neuron image blocks based on deep learning

open access: yesBrain Informatics, 2021
Quickly and accurately tracing neuronal morphologies in large-scale volumetric microscopy data is a very challenging task. Most automatic algorithms for tracing multi-neuron in a whole brain are designed under the Ultra-Tracer framework, which begins the

Incomplete dominance of deleterious alleles contributes substantially to trait variation and heterosis in maize. [PDF]

open access: yesPLoS Genetics, 2017
Deleterious alleles have long been proposed to play an important role in patterning phenotypic variation and are central to commonly held ideas explaining the hybrid vigor observed in the offspring of a cross between two inbred parents.

A Bit-Parallel Tabu Search Algorithm for Finding Es2-Optimal and Minimax-Optimal Supersaturated Designs

open access: yesComputational and Mathematical Methods, 2023
We prove the equivalence of two-symbol supersaturated designs (SSDs) with N (even) rows, m columns, and smax=4t+i, where i∈0,2 and t∈ℤ≥0 and resolvable incomplete block designs (RIBDs) whose any two blocks intersect in at most N+4t+i/4 points. Using this

Comparison Between some Methods of Tackling the Lack of Experimental Units Needed for Application of Factorial Experiments [PDF]

open access: yesالمجلة 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 ...
