We consider classical dynamics of UV Lamps a one-dimensional system of N particles bouncing on an oscillating mirror in the presence of gravitational field.The particles behave like hard balls and they are resonantly driven by the mirror.We identify the manifolds the particles move on and derive the effective secular Hamiltonian for resonant motion
An experimental study of cyclone Hard Hat filters of various designs is conducted.The parameters that allow increasing the degree of air purification from dust are identified: air pressure at the filter inlet, working air temperature, as well as the diameter of the nozzle of the purified air consumer simulator and the diameter of the ventilation no
