Automation

Automation can be defined as the technology by which a process or procedure is performed without human assistance.[2]
In other words, Automation[1] or automatic control, is the use of various control systemsfor operating equipment such as machinery, processes in factories, boilers and heat treating ovens, switching on telephone networks, steering and stabilization of ships, aircraft and other applications and vehicles with minimal or reduced human intervention, with some processes have been completely automated.
Automation has been achieved by various means including mechanical, hydraulic, pneumatic, electrical, electronic devices and computers, usually in combination. Complicated systems, such as modern factories, airplanes and ships typically use all these combined techniques. The benefit of automation include labor savings, savings in electricity costs, savings in material costs, and improvements to quality, accuracy and precision.
The term automation, inspired by the earlier word automatic (coming from automaton), was not widely used before 1947, when Ford established an automation department.[1] It was during this time that industry was rapidly adopting feedback controllers, which were introduced in the 1930s.[3]

Mirror

Image
A mirror, reflecting a  vase A  first surface mirror  coated with aluminum and enhanced with  dielectric  coatings. The angle of the incident light (represented by both the light in the mirror and the shadow behind it) exactly matches the angle of reflection (the reflected light shining on the table). A  mirror  is an object that  reflects  light in such a way that, for incident light in some range of wavelengths, the reflected light preserves many or most of the detailed physical characteristics of the original light. This is different from other light-reflecting objects that do not preserve much of the original wave signal other than color and diffuse reflected light. The most familiar type of mirror is the  plane mirror , which has a flat screen surface.  Curved mirrors  are also used, to produce  magnified  or diminished images or focus light or simply distort the reflected image. Mirrors are commonly used for  personal grooming  or admiring oneself (where they ar

Austria

On 12 March, Austria was annexed to the  Third Reich  and ceased to exist as an independent country. The  Aryanisation  of the wealth of Jewish Austrians started immediately in mid-March, with a so-called "wild" (i.e. extra-legal) phase, but was soon structured legally and bureaucratically to strip Jewish citizens of any assets they possessed. The Nazis called Austria " Ostmark " [64]  until 1942, when it was again renamed and called "Alpen-Donau-Reichsgaue". Though Austrians made up only 8% of the population of the Third Reich, [69]  some of the most prominent Nazis were native Austrians, including Adolf Hitler,  Ernst Kaltenbrunner ,  Arthur Seyss-Inquart ,  Franz Stangl , and  Odilo Globocnik , [70]  as were over 13% of the  SS  and 40% of the staff at the Nazi  extermination camps . [69]  Vienna fell on 13 April 1945, during the  Soviet   Vienna Offensive , just before the total collapse of the Third Reich. The invading Allied powers, in particula
