Navigation 13 – Spherical Position and Local Plan – Spherical Trajectories ?

How do we set a Position on Earth and how we determine Local Coordinates and Perpendicular Plan ? And then how do we find trajectories point by point on Earth ? With and … without Latitude and Longitude, only with an Absolute Rotation Angle ? We want to « navigate » on earth with direct trajectory from […]

Artificial Intelligence 06 – Neurones Concepts Recognition by 256 Synapses

How to simulate a pattern recognition ? For exemple we have to learn by training to recognize the 10 first arabian letters to assignate to « zero » to « nine » concepts. Where are Synapses ? Where are the Neurones ? Where are the Concepts Localization on Brain ? Let’s see a Matlab simulation for a prototype without […]

Algorithmics 07 – From Shannon to Karatsuba or the Reverse ?

We can observe C. Shannon as a genius engineer and Karatsuba as a smart mathematician. But how did they think about physics and how Shannon explained theories ? Do discovers follow ideas or the invert ? You can follow in direct live my own postdoc research on subject « How to improve Signal Behaviour ? » Why ? « To improve accuracy […]

Algorithmic 06 – The Billion, the Billion* ! Primes !

Here after two days calculations by a simple computer with no bugs we do 1 billion searches by number of prime numbers in parts of density number then we do   divisions. It is a … great number. (*) : The billion, the billion : Title of a caricatural joke by « Les inconnus » to describe the […]
