Scrutin uninominal majoritaire à un tourthumb|Schéma du mode de scrutin majoritaire Le scrutin uninominal majoritaire à un tour est le système électoral pour lequel il est le plus simple de déterminer l'option gagnante à partir des votes. L'électeur doit choisir un candidat parmi plusieurs. On compte alors le nombre de voix obtenues par chaque candidat. Celui qui recueille le plus de voix (majorité relative) remporte les élections. Ce système de vote est utilisé pour l'élection du président de la République dans certains pays (Cameroun, Corée du Sud, Islande, Kenya, Malawi, Mexique, Philippines, Venezuela, République démocratique du Congo, Togo, Taïwan).
Mixed-member proportional representationMixed-member proportional representation (MMP or MMPR) is a mixed electoral system in which votes are cast for both local elections and also for overall party vote tallies, which are used to allocate additional members to produce or deepen overall proportional representation. In some MMP systems, voters get two votes: one to decide the representative for their single-seat constituency, and one for a political party. In Denmark and others, the single vote cast by the voter is used for both the local election (in a multi-member or single-seat district), and for the overall top-up.
Mixed-member majoritarian representationMixed member majoritarian representation (MMM) is type of a mixed electoral system combining majoritarian and proportional methods, where the disproportional results of the majoritarian side of the system prevail over the proportional component. Mixed member majoritarian systems are therefore also as a type of semi-proportional representation, and are usually contrasted with mixed-member proportional representation (MMP) which aims to provide proportional representation via additional compensation ("top-up") seats.
Robot end effectorIn robotics, an end effector is the device at the end of a robotic arm, designed to interact with the environment. The exact nature of this device depends on the application of the robot. In the strict definition, which originates from serial robotic manipulators, the end effector means the last link (or end) of the robot. At this endpoint, the tools are attached. In a wider sense, an end effector can be seen as the part of a robot that interacts with the work environment.
Robotique industriellevignette|droite|Un robot industriel Kawasaki FS-03N, robot de soudage La robotique industrielle est officiellement définie par l'Organisation Internationale de Normalisation (ISO) comme étant un système commandé automatiquement, multi-applicatif, reprogrammable, polyvalent, manipulateur et programmable sur trois axes ou plus. Les applications typiques incluent les robots de soudage, de peinture et d'assemblage. L'avantage de la robotique industrielle est sa rapidité d'exécution et sa précision ainsi que la répétition de cette précision dans le temps.
Dual-member proportional representationDual-member proportional representation (DMP), also known as dual-member mixed proportional, is an electoral system designed to produce proportional election results across a region by electing two representatives in each of the region’s districts. The first seat in every district is awarded to the candidate who receives the most votes, similar to first-past-the-post voting (FPTP). The second seat is awarded to one of the remaining district candidates so that proportionality is achieved across the region, using a calculation that aims to award parties their seats in the districts where they had their strongest performances.
Bio-inspired roboticsBio-inspired robotic locomotion is a fairly new subcategory of bio-inspired design. It is about learning concepts from nature and applying them to the design of real-world engineered systems. More specifically, this field is about making robots that are inspired by biological systems, including Biomimicry. Biomimicry is copying from nature while bio-inspired design is learning from nature and making a mechanism that is simpler and more effective than the system observed in nature.
Mobile robotA mobile robot is an automatic machine that is capable of locomotion. Mobile robotics is usually considered to be a subfield of robotics and information engineering. Mobile robots have the capability to move around in their environment and are not fixed to one physical location. Mobile robots can be "autonomous" (AMR - autonomous mobile robot) which means they are capable of navigating an uncontrolled environment without the need for physical or electro-mechanical guidance devices.
Usure des surfacesDans la science des matériaux, l'usure des surfaces désigne le phénomène de dégradation des couches superficielles d'un solide sous l'action mécanique du milieu extérieur. Cette dégradation est souvent associée aux phénomènes chimiques dus à la corrosion, elle peut prendre la forme d'une perte de masse, de cote, de forme, ou encore d'une modification de la structure. L'étude des phénomènes d'usure est un des domaines de la tribologie. Usure par laminage. Usure par corrosion. Usure par adhérence.
Construction parasismiquethumb| La Tokyo Skytree, la deuxième plus grande tour au monde (derrière le Burj Khalifa) qui, du haut de ses , a parfaitement résisté au séisme de 2011 de magnitude 9, démontrant l'efficacité des constructions parasismiques japonaises. La construction parasismique ou construction antisismique est la réalisation de bâtiments et infrastructures résistant aux séismes. Elle implique l'étude du comportement des bâtiments et structures sujets à un chargement dynamique de type sismique.
