A particularly large number of works are related to the application of the oscillator on a water piston pump, and the largest number of works comes from the second most populous country in the world, India. The following scientific work deals with the parametric analysis of the two-stage mechanical oscillator.
Research into the possibility of applying the two-stage mechanical oscillator by academician Veljko Milković in the world is not waning. Every year, several scientific papers are published around the world that deal with the specific application of the two-stage mechanical oscillator, and a lot of these scientific research papers are related to its application on the hand water pump. The following scientific paper was published in Nepal, at Kathmandu University located at the municipality of Dhulikhel.
Academician Veljko Milković's two-stage mechanical oscillator is being researched all over the world. Every year, several scientific papers are published around the world dealing with the application of this invention, and many of these papers are research related to the application of this oscillator to hand-operated water pumps. The following scientific paper was published in Poland, at the University of Technology in the city of Łódź
International research of Milković's water pumps is not abating. However, there are papers, such as this one, in which Veljko Milković is not mentioned anywhere, although it is obvious that it is his invention. The following scientific paper was published in India.
