Structural engineerStructural engineers analyze, design, plan, and research structural components and structural systems to achieve design goals and ensure the safety and comfort of users or occupants. Their work takes account mainly of safety, technical, economic, and environmental concerns, but they may also consider aesthetic and social factors. Structural engineering is usually considered a specialty discipline within civil engineering, but it can also be studied in its own right.
Calcul des structures et modélisationLe calcul des structures et la modélisation concernent deux domaines distincts : d'une part les applications spécifiques au patrimoine architectural, mobilier et naturel et d'autre part les applications industrielles. Le calcul des structures et leur modélisation est utilisé dans les domaines : de la conservation et mise en valeur du patrimoine architectural, mobilier et naturel, dans le cadre de missions d’assistance à la maître d’œuvre ou au maître d’ouvrage permettant d’arrêter un programme de travaux, d’applications industrielles.
Structural integrity and failureStructural integrity and failure is an aspect of engineering that deals with the ability of a structure to support a designed structural load (weight, force, etc.) without breaking and includes the study of past structural failures in order to prevent failures in future designs. Structural integrity is the ability of an item—either a structural component or a structure consisting of many components—to hold together under a load, including its own weight, without breaking or deforming excessively.
Zéro déchetalt=Décharge.|vignette|Le mouvement zéro déchet s'oppose aux modes de traitement des déchets polluants et à ceux qui détruisent inutilement des ressources. vignette|L'un des principes du zéro déchet est d'éviter les produits jetables en les remplaçant par des alternatives réutilisables. Le zéro déchet (de l'anglais zero waste) est un mouvement de protection de l'environnement qui vise à réduire le gaspillage de ressources, la quantité déchets émis et leur toxicité.
Structure algébriqueEn mathématiques, une structure algébrique est définie axiomatiquement par une ou plusieurs opérations sur un ensemble (dites internes), éventuellement muni d’autres opérations (externes) dépendant d’autres ensembles, toutes ces opérations satisfaisant certaines relations telles que l’associativité, la commutativité ou la distributivité. La structure de groupe qui émerge progressivement au , avec une seule opération interne et quelques propriétés se formalise au début du avec une kyrielle de structures d’algèbre générale moins restrictives (monoïde) ou au contraire enrichies par une seconde opération (anneau, corps, algèbre de Boole.
Conception participativeLa conception participative, ou coconception, que l'on retrouve couramment sous le terme codesign, co-design et design participatif, est une méthode de travail qui implique l'utilisateur final, lors d'un processus de développement et de conception d'un produit ou d'un service. Il s'agit donc d'une méthode de conception centrée sur l'utilisateur où l'accent est mis sur le rôle actif des utilisateurs.
Design methodsDesign methods are procedures, techniques, aids, or tools for designing. They offer a number of different kinds of activities that a designer might use within an overall design process. Conventional procedures of design, such as drawing, can be regarded as design methods, but since the 1950s new procedures have been developed that are more usually grouped together under the name of "design methods". What design methods have in common is that they "are attempts to make public the hitherto private thinking of designers; to externalise the design process".
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.
Computational economicsComputational Economics is an interdisciplinary research discipline that involves computer science, economics, and management science. This subject encompasses computational modeling of economic systems. Some of these areas are unique, while others established areas of economics by allowing robust data analytics and solutions of problems that would be arduous to research without computers and associated numerical methods.
Common stockCommon stock is a form of corporate equity ownership, a type of security. The terms voting share and ordinary share are also used frequently outside of the United States. They are known as equity shares or ordinary shares in the UK and other Commonwealth realms. This type of share gives the stockholder the right to share in the profits of the company, and to vote on matters of corporate policy and the composition of the members of the board of directors.
Utilisation des excretavignette|Récolte de poivrons (capsicum) cultivés avec du compost à base d'excréments dans un jardin expérimental en Haïti L'utilisation des excréments ou utilisation des excreta fait ici référence à l'utilisation des excréments animaux et/ou excréments humains, à savoir les matières fécales (ou fèces) et l'urine. Il s'agit de valoriser la matière organique et les nutriments qu'ils contiennent naturellement sous des formes bioassimilables pour les plantes. On en fait des amendement ou des engrais en agriculture, jardinage, aquaculture ou activités horticoles.
User experience designUser experience design (UX design, UXD, UED, or XD) is the process of defining the experience a user would go through when interacting with a company, its services, and its products. Design decisions in UX design are often driven by research, data analysis, and test results rather than aesthetic preferences and opinions. Unlike user interface design, which focuses solely on the design of a computer interface, UX design encompasses all aspects of a user's perceived experience with a product or website, such as its usability, usefulness, desirability, brand perception, and overall performance.
