Around forty years passed from the beginning of operation of the first electron-positron colliding beam facility VEPP-2 in Institute of Nuclear Physics (INP), Novosibirsk. Here I described development of electron-positron colliding beam project in INP, as well as advance of similar projects of the first generation at LAL, Orsay and at LNF, Frascati.

Abstract Controlling the deformation of a soft body has potential applications in fields requiring precise control over shape body. Areas such as medical robotics can use robots to repair aneurysms humans, deliver medicines within body, among other applications. However, given known external loading, it is usually not possible deform into arbitrary shapes if fabricated using only single materia...

Design solutions for the shape of gear bodies depend on several factors such as size wheel, material, production method or use. Cast forged welded gears are used larger wheels. One requirements is weight reduction. Such an effort can be achieved by changing dimensions given while maintaining required stiffness gearing. The paper devoted to problem optimizing in order reduce gears, but best poss...
