Résumé

Direct constructions for balanced tournaments known so far solve problems with 2n teams if 2n mod 3 not equal 1 or 2n = 2(p), p >= 3 or n is odd. Our construction uses an arbitrary partition of the league into subleagues. It solves more than half of the missing cases and provides structured solutions for some known cases.

Construction

vignette|upright|Les grues sont essentielles pour des travaux importants tels que les gratte-ciel. La construction est le fait d'assembler différents éléments d'un édifice en utilisant des matériaux et des techniques appropriées. Le secteur économique de la construction, appelé « bâtiment et travaux publics » (BTP) dans une partie de l'Europe francophone, regroupe toutes les activités de conception et de construction des bâtiments publics et privés, industriels ou non, et des infrastructures telles que les routes ou les canalisations.

Construction management

Construction management (CM) is a professional service that uses specialized, project management techniques and software to oversee the planning, design, construction and closeout of a project. The purpose of construction management is to control the quality of a project's scope, time / delivery and cost—sometimes referred to as a project management triangle or "triple constraints." CM is compatible with all project delivery systems, including design-bid-build, design-build, CM At-Risk and Public Private Partnerships.

Direct sum

The direct sum is an operation between structures in abstract algebra, a branch of mathematics. It is defined differently, but analogously, for different kinds of structures. To see how the direct sum is used in abstract algebra, consider a more elementary kind of structure, the abelian group. The direct sum of two abelian groups and is another abelian group consisting of the ordered pairs where and . To add ordered pairs, we define the sum to be ; in other words addition is defined coordinate-wise.

Rising from rubble - Leveraging existing construction tools for upcycling concrete waste into slender walls

Katrin Beyer, Maxence Grangeot, Corentin Jean Dominique Fivet, Qianqing Wang, Stefana Parascho

In this paper, we present a new method for upcycling concrete rubble waste into slender walls through the lightweight digital augmentation of mainstream construction machines. By using such method, the environmental impact of concrete construction and demo ...

FLO:RE – A new floor system made of reused reinforced concrete and steel elements

Maléna Bastien Masse, Numa Joy Bertola, Célia Marine Küpfer, Corentin Jean Dominique Fivet

Carefully extracting reinforced concrete (RC) elements from soon-to-be demolished structures and reusing them as load-bearing components is an emerging circular low-carbon alternative to building new structures. As floor construction typically accounts for ...
