This book aims to achieve a scientific group known like planetary type mechanisms. Constructively, structurally and kinematically, the planetary mechanisms (the planetary trains) are generally composed of spur gears and bars. In premiere, the book de (...)

Development and diversification of machines and mechanisms with applications in all areas of scientific research requires new systematization and improvement of existing mechanical systems by creating new mechanisms adapted to the modern requirements (...)

Mechanical Systems, Serial and Parallel Short description This paper is a scientific view, uniform, general, comprehensive and unbiased of the main problems posed by mechanical systems, mobile, serial and parallel. It gives an overview, followed (...)

We can extract the energy of the rest mass of an electron. For a pair of an electron and a positron this energy is circa 1 MeV. The "synchrotron radiation (synchrotron light source)" produces deliberated a radiation source. Electrons are accelerated (...)
