Comparative Study on Shading Database Construction for Urban Roads Using 3D Models and Fisheye Images for Efficient Operation of Solar-Powered Electric Vehicles

open access: yesEnergies, 2022
Accounting for shadows on urban roads is a complex task in the operation of solar-powered electric vehicles. There have been few opportunities to compare the methods and tools for the construction of an effective shading database for urban roads.

Effects of the Mortar Matrix on the Flexural Capacity of Masonry Cross Sections Strengthened with FRCM Materials

open access: yesApplied Sciences, 2020
The strengthening intervention strategies that exist for masonry buildings are based on the use of thin composites and are a recent activity used in structural engineering. Nowadays, mortar matrices are frequently found instead of epoxy resins, since the

The hidden geometry of MUSAC. Field systems as the origin of form in the contemporary project

open access: yesCuadernos de Proyectos Arquitectónicos, 2020
The origin of the contemporary project’s form has become an enigma. The process of drawing up a project ends up being a superimposed, diluted reality, hidden by the narratives constructed by their authors. At some point, in which the process becomes more

La geometría oculta del MUSAC. Sistemas de campo como origen de la forma en el proyecto contemporáneo = The hidden geometry of MUSAC. Field systems as the origin of form in the contemporary project

open access: yesCuadernos de Proyectos Arquitectónicos, 2020
Resumen El origen de la forma en el proyecto contemporáneo se ha convertido en un enigma. La realidad del proceso del proyecto queda superpuesta, diluida y oculta por las narrativas construidas, posteriormente, por sus autores.

Opposition diagrams for automorphisms of large spherical buildings [PDF]

open access: yes, 2018
Let $\theta$ be an automorphism of a thick irreducible spherical building $\Delta$ of rank at least $3$ with no Fano plane residues. We prove that if there exist both type $J_1$ and $J_2$ simplices of $\Delta$ mapped onto opposite simplices by $\theta ...

Opposition diagrams for automorphisms of small spherical buildings [PDF]

open access: yes, 2019
An automorphism $\theta$ of a spherical building $\Delta$ is called \textit{capped} if it satisfies the following property: if there exist both type $J_1$ and $J_2$ simplices of $\Delta$ mapped onto opposite simplices by $\theta$ then there exists a type

Time indeterminacy and spatio-temporal building transformations: an approach for architectural heritage understanding [PDF]

open access: yes, 2009
Nowadays most digital reconstructions in architecture and archeology describe buildings heritage as awhole of static and unchangeable entities. However, historical sites can have a rich and complex history, sometimes full of evolutions, sometimes only ...

Diagrammatic Reasoning and Modelling in the Imagination: The Secret Weapons of the Scientific Revolution [PDF]

open access: yes, 2000
Just before the Scientific Revolution, there was a "Mathematical Revolution", heavily based on geometrical and machine diagrams. The "faculty of imagination" (now called scientific visualization) was developed to allow 3D understanding of planetary ...

Power adjustment and scheduling in OFDMA femtocell networks [PDF]

open access: yes, 2016
Densely-deployed femtocell networks are used to enhance wireless coverage in public spaces like office buildings, subways, and academic buildings. These networks can increase throughput for users, but edge users can suffer from co-channel interference ...

Extended F_4-buildings and the Baby Monster

open access: yes, 2000
The Baby Monster group B acts naturally on a geometry E(B) with diagram c.F_4(t) for t=4 and the action of B on E(B) is flag-transitive. It possesses the following properties: (a) any two elements of type 1 are incident to at most one common element ...
