North African countries spend a comparative 0.4% of GDP on research, an increase from US$2.6bn in 2002 to US$3.3bn in 2007.
In essence, the Fourth Industrial Revolution is the trend towards automation and data exchange in manufacturing technologies and processes which include cyber-physical systems (CPS), Internet of Things (IoT), [25] cloud computing, [26][27][28][29] cognitive computing, and artificial intelligence. [29][30] Machines improve human efficiency in ...
Steam engines promoted automation through the need to control engine speed and power.. The introduction of prime movers, or self-driven machines advanced grain mills, furnaces, boilers, and the steam engine created a new requirement for automatic control systems including temperature regulators (invented in 1624; see Cornelius Drebbel), pressure regulators (1681), float regulators (1700) and ...
t. e. The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a period of global transition of the human economy towards more widespread, efficient and stable manufacturing processes that succeeded the Agricultural Revolution.

The history of robots has its origins in the ancient world. During the Industrial Revolution, humans developed the structural engineering capability to control electricity so that machines could be powered with small motors. In the early 20th century, the notion of a humanoid machine was developed.
1959 – Trevor Wadley invented the Tellurometer, the first successful microwave distance measurement device. 1962 – SANAE I, the first South African Antarctic base is built. [ 22][ 23] 1963 – The Dolos was developed in East London. 1965, 18 March – SAFARI-1, the first nuclear reactor on the African continent, goes critical.
1920-1925. Wilhelm Lenz and Ernst Ising created and analyzed the Ising model (1925) [45] which can be viewed as the first artificial recurrent neural network (RNN) consisting of neuron-like threshold elements. [9] In 1972, Shun'ichi Amari made this architecture adaptive. [46][9] 1920s and 1930s.
History of Africa. Archaic humans emerged out of Africa between 0.5 and 1.8 million years ago. This was followed by the emergence of modern humans (Homo sapiens) in East Africa around 300,000–250,000 years ago. In the 4th millenium BC written history arose in Ancient Egypt, [1] and later in Nubia 's Kush, the Horn of Africa 's Dʿmt, and ...
