Software requirements specificationA software requirements specification (SRS) is a description of a software system to be developed. It is modeled after the business requirements specification (CONOPS). The software requirements specification lays out functional and non-functional requirements, and it may include a set of use cases that describe user interactions that the software must provide to the user for perfect interaction.
Satellite geodesySatellite geodesy is geodesy by means of artificial satellites—the measurement of the form and dimensions of Earth, the location of objects on its surface and the figure of the Earth's gravity field by means of artificial satellite techniques. It belongs to the broader field of space geodesy. Traditional astronomical geodesy is not commonly considered a part of satellite geodesy, although there is considerable overlap between the techniques.
GéotagUn géotag est un marqueur (« tag », en anglais) à caractère géographique inséré dans des fichiers audio ou raster dans champs (JPEG, , ), IPTC (JPEG/), XMP (très nombreux formats). Le terme en français est « balise de géolocalisation ». Cette balise peut notamment contenir : des données GPS ou GNSS (coordonnées latitude et longitude, une altitude) la direction de vue (boussole) des informations saisies par l'utilisateur : lieux de saisie, code postal...
3D scanning3D scanner is the process of analyzing a real-world object or environment to collect three dimensional data of its shape and possibly its appearance (e.g. color). The collected data can then be used to construct digital 3D models. A 3D scanner can be based on many different technologies, each with its own limitations, advantages and costs. Many limitations in the kind of objects that can be digitised are still present. For example, optical technology may encounter many difficulties with dark, shiny, reflective or transparent objects.
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.
Système géodésiqueUn système géodésique est un système de référence permettant d'exprimer les positions au voisinage de la Terre. Un système géodésique est, initialement, un repère tridimensionnel défini par : son centre O (choisi à proximité du centre de gravité terrestre) trois axes orthonormés Ox, Oy et Oz, définis par leur orientation. Ox et Oy se trouvent pratiquement dans le plan équatorial terrestre, et Oz est orienté approximativement suivant l'axe de rotation terrestre.
Macle (cristallographie)thumb|right|Macle par pénétration de trois cristaux de pyrite. Une macle est une association orientée de plusieurs cristaux identiques, dits individus, reliés par une opération de groupe ponctuel de symétrie. Les cristaux formant une macle ont en commun un réseau qui s'appelle réseau de la macle. Ce réseau est formé par les nœuds des réseaux des individus maclés qui sont superposés par l'opération de macle. Selon que ce réseau existe en une, deux ou trois dimensions, les macles sont dites monopériodiques, dipériodiques et tripériodiques respectivement.
Stress–strain curveIn engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain. It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing). These curves reveal many of the properties of a material, such as the Young's modulus, the yield strength and the ultimate tensile strength. Generally speaking, curves representing the relationship between stress and strain in any form of deformation can be regarded as stress–strain curves.
Structural loadA structural load or structural action is a force, deformation, or acceleration applied to structural elements. A load causes stress, deformation, and displacement in a structure. Structural analysis, a discipline in engineering, analyzes the effects of loads on structures and structural elements. Excess load may cause structural failure, so this should be considered and controlled during the design of a structure. Particular mechanical structures—such as aircraft, satellites, rockets, space stations, ships, and submarines—are subject to their own particular structural loads and actions.
Medical image computingMedical image computing (MIC) is an interdisciplinary field at the intersection of computer science, information engineering, electrical engineering, physics, mathematics and medicine. This field develops computational and mathematical methods for solving problems pertaining to medical images and their use for biomedical research and clinical care. The main goal of MIC is to extract clinically relevant information or knowledge from medical images.
