Cement and Concrete Research, 2019
Abstract As a first step toward characterising structural build-up of high-strength, printable concrete mixes, the structural build-up of cement pastes of varying compositions and rheological properties is investigated. It is demonstrated that applying low shear rates over short measurement periods does not always result in the achievement of flow ...

The build-up construction over a commutative non-unital ring
Designs, Codes and Cryptography, 2022Let \(I\) be the commutative ring with four elements \(0,a,b,c\) (without identity) defined by the rules \(2a=2b=0\), \(a+b=c\), \(a^2=b\), \(ab=0\). A \textit{liner \(I\)-code} of length \(n\) is an \(I\)-submodule of \(I^n\). In the paper, ``the \(I\)-span of the rows of a generator matrix'' includes the rows of the generator matrix even though \(I\)

Build-up Construction in Salt Formations
Offshore Technology Conference, 2011Abstract The history of directional drilling in salt formation has shown that oil companies have a conservative approach regarding the limits of dog-legs (DL). Most companies recommend projects with DL at about 2 degrees/30 m for the build-up construction in directional wells.

Self-dual codes using the building-up construction
2009 IEEE International Symposium on Information Theory, 2009The building-up construction for self-dual codes was developed by the authors over finite fields GF(q) when q is a power of 2 or q ≡ 1 (mod 4). In this paper, we complete the building-up construction for self-dual codes over GF(q) with q ≡ 3 (mod 4).

Construction of LU Factors of the Basis to Reduce Build-up During Simplex Iterations
Journal of the Operational Research Society, 1992Summary: Algorithms for the inversion of a sparse square matrix have generally been designed with the aim of minimizing the number of calculations required to factorize the matrix and to solve for one or more right-hand sides. This usually involves attempting to minimize the number of non- zero in the factors of the inverse.

The build-up of value in manufacturing and construction and in the economy
Engineering Costs and Production Economics, 1989Abstract All production is ultimately for the purpose of satisfying consumers. The paper shows how value builds up in the industrial processes by which raw materials are progressively converted into consumer products and how the summation of these processes gives rise to National Product. One aim is to bridge the gap between the manner in which these
