Bois d'œuvrethumb|upright=1.5|Structure construite en bois. Le bois est un matériau de construction employé dans la construction des bâtiments. thumb|upright=1.5|Parties du bois d'œuvre. La construction fait appel au duramen, appelé aussi « bois parfait » ou « bois de cœur », qui constitue la partie centrale de l’arbre. Le duramen est biologiquement quasi-inerte et plus durable que l’aubier — celui-ci, souvent plus clair et léger, étant constitué de cellules vivantes. L'aubier est plus facilement et rapidement attaqué par les insectes, bactéries et champignons.
Home constructionHome construction or residential construction is the process of constructing a house, apartment building, or similar residential building generally referred to as a 'home' when giving consideration to the people who might now or someday reside there. Beginning with simple pre-historic shelters, home construction techniques have evolved to produce the vast multitude of living accommodations available today. Different levels of wealth and power have warranted various sizes, luxuries, and even defenses in a "home".
StructureA structure is an arrangement and organization of interrelated elements in a material object or system, or the object or system so organized. Material structures include man-made objects such as buildings and machines and natural objects such as biological organisms, minerals and chemicals. Abstract structures include data structures in computer science and musical form. Types of structure include a hierarchy (a cascade of one-to-many relationships), a network featuring many-to-many links, or a lattice featuring connections between components that are neighbors in space.
Structural genomicsStructural genomics seeks to describe the 3-dimensional structure of every protein encoded by a given genome. This genome-based approach allows for a high-throughput method of structure determination by a combination of experimental and modeling approaches. The principal difference between structural genomics and traditional structural prediction is that structural genomics attempts to determine the structure of every protein encoded by the genome, rather than focusing on one particular protein.
Liste de corps d'étatCet article constitue une liste rassemblant selon les répartitions communément usitées les corps de métier dans le domaine du génie civil, communément désignés sous l'appellation collective de corps d'état. Il s'agit d'appellations couramment rencontrées dans les allotissements des marchés de travaux.
Structural steelStructural steel is a category of steel used for making construction materials in a variety of shapes. Many structural steel shapes take the form of an elongated beam having a of a specific cross section. Structural steel shapes, sizes, chemical composition, mechanical properties such as strengths, storage practices, etc., are regulated by standards in most industrialized countries. Most structural steel shapes, such as -beams, have high second moments of area, which means they are very stiff in respect to their cross-sectional area and thus can support a high load without excessive sagging.
Structural alignmentStructural alignment attempts to establish homology between two or more polymer structures based on their shape and three-dimensional conformation. This process is usually applied to protein tertiary structures but can also be used for large RNA molecules. In contrast to simple structural superposition, where at least some equivalent residues of the two structures are known, structural alignment requires no a priori knowledge of equivalent positions.
Framing (construction)Framing, in construction, is the fitting together of pieces to give a structure support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called mass wall construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing.
Image numériqueL'appellation d'image numérique désigne toute (dessin, icône, photographie...) acquise, créée, traitée et stockée sous forme binaire : acquise par des convertisseurs analogique-numérique situés dans des dispositifs comme les scanners, les appareils photo ou les caméscopes numériques, les cartes d’acquisition vidéo (qui numérisent directement une source comme la télévision) créée directement par des programmes informatiques, grâce à une souris, des tablettes graphiques ou par de la modélisation 3D (ce que l’on appelle, par abus de langage, les « images de synthèse ») ; traitée grâce à des outils graphiques, de façon à la transformer, à en modifier la taille, les couleurs, d’y ajouter ou d'en supprimer des éléments, d’y appliquer des filtres variés stockée sur un support informatique (clé USB, SSD, disque dur, CD-ROM.
Pontvignette|Pont permettant le passage de la ligne C du métro de Rotterdam, à Capelle-sur-l'Yssel (Pays-Bas). vignette|Pont sur la rivière Moyka à Saint-Pétersbourg, Russie Un pont est un ouvrage d'art qui permet de franchir un obstacle naturel ou artificiel (dépression, cours d'eau, voie de communication, vallée, ravin, canyon) en passant par-dessus. Le franchissement supporte le passage d'humains et de véhicules dans le cas d'un pont routier, ou d'eau dans le cas d'un aqueduc.
