Likewise, a Feedback Control System is a system which tends to maintain a prescribed relationship of one system variable to another by comparing functions of these variables and using the difference as a means of control.[6] The advanced type of automation that revolutionized manufacturing, aircraft, communications and other industries, is feedback control, which is usually continuous and involves taking measurements using a sensor and making calculated adjustments to keep the measured variable within a set range.[7][8] The theoretical basis of closed loop automation is control theory.

This VBA statement says: Find the search box element on the webpage by its ID, which is search_form_input_homepage, and make its text value what we have in cell A2, plus the string " in ", plus what we have in cell C1. The underscore (_) just lets us put longer pieces of code on multiple lines for better readability. How did I know what the search input box’s ID was, or that it even had an ID? Firebug of course! If you don’t have Firefox get it, and then install the Firebug add-on. Then right-click the search box, click Inspect Element with Firebug, and behold…

The automation of vehicles could prove to have a substantial impact on the environment, although the nature of this impact could be beneficial or harmful depending on several factors. Because automated vehicles are much less likely to get into accidents compared to human-driven vehicles, some precautions built into current models (such as anti-lock brakes or laminated glass) would not be required for self-driving versions. Removing these safety features would also significantly reduce the weight of the vehicle, thus increasing fuel economy and reducing emissions per mile. Self-driving vehicles are also more precise with regard to acceleration and breaking, and this could contribute to reduced emissions. Self-driving cars could also potentially utilize fuel-efficient features such as route mapping that is able to calculate and take the most efficient routes. Despite this potential to reduce emissions, some researchers theorize that an increase of production of self-driving cars could lead to a boom of vehicle ownership and use. This boom could potentially negate any environmental benefits of self-driving cars if a large enough number of people begin driving personal vehicles more frequently.[53]


Dans le chapitre « Assemblage des fragments  »  : […] de la bio-informatique est l'aide à la « mise en forme » des génomes de grande taille. En effet, grâce aux apports de la robotique, le biologiste peut désormais séquencer des génomes complets. Toutefois, la technologie des robots ne permet pas de traiter plus de 700 nucléotides sur un seul fragment d'ADN à la fois : le génome est donc découpé, au […] Lire la suite☛ http://www.universalis.fr/encyclopedie/biologie-la-bio-informatique/#i_2513
