An early development of sequential control was relay logic, by which electrical relays engage electrical contacts which either start or interrupt power to a device. Relays were first used in telegraph networks before being developed for controlling other devices, such as when starting and stopping industrial-sized electric motors or opening and closing solenoid valves. Using relays for control purposes allowed event-driven control, where actions could be triggered out of sequence, in response to external events. These were more flexible in their response than the rigid single-sequence cam timers. More complicated examples involved maintaining safe sequences for devices such as swing bridge controls, where a lock bolt needed to be disengaged before the bridge could be moved, and the lock bolt could not be released until the safety gates had already been closed.
Full automation commonly defined as requiring no control or very limited control by the driver; such automation would be accomplished through a combination of sensor, computer, and communications systems in vehicles and along the roadway. Fully automated driving would, in theory, allow closer vehicle spacing and higher speeds, which could enhance traffic capacity in places where additional road building is physically impossible, politically unacceptable, or prohibitively expensive. Automated controls also might enhance road safety by reducing the opportunity for driver error, which causes a large share of motor vehicle crashes. Other potential benefits include improved air quality (as a result of more-efficient traffic flows), increased fuel economy, and spin-off technologies generated during research and development related to automated highway systems.
L'idée c'est de complètement scripter l'utilisation d'un navigateur (analyse de contenu de page, clicks, etc.) que ce soit sur une seule page ou pour des sessions de navigation longues. Pour les analyses de pages tu peux faire vraiment tout et n'importe quoi en XPath. C'est assez puissant mais il faut un peu d’expérience pour certains scénarios un peu tricky.
I’m not a programmer by trade. Just a short while back, I knew nothing about it. But with a few VBA beginner courses, help from quick-answer sites like stackoverflow.com, and a willingness to learn, anyone can code. Now VBA is a fun hobby and I’ve helped lots of people automate daily tasks and turn small projects into big ones with bots over the past 6 years.
Information technology, together with industrial machinery and processes, can assist in the design, implementation, and monitoring of control systems. One example of an industrial control system is a programmable logic controller (PLC). PLCs are specialized hardened computers which are frequently used to synchronize the flow of inputs from (physical) sensors and events with the flow of outputs to actuators and events.
Today extensive automation is practiced in practically every type of manufacturing and assembly process. Some of the larger processes include electrical power generation, oil refining, chemicals, steel mills, plastics, cement plants, fertilizer plants, pulp and paper mills, automobile and truck assembly, aircraft production, glass manufacturing, natural gas separation plants, food and beverage processing, canning and bottling and manufacture of various kinds of parts. Robots are especially useful in hazardous applications like automobile spray painting. Robots are also used to assemble electronic circuit boards. Automotive welding is done with robots and automatic welders are used in applications like pipelines.
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
