In this paper, the possibility of using piezoelectric elements to create a prestress state in a
plate and a shallow shell leading to a change in the natural frequencies is demonstrated …

Nowadays, the application of composite materials and light-weight structures is required in
those industrial applications where the primary design aims are weight saving, high …

The paper deals with the development of a dimensional rock sawing machine to optimize
the production of small-volume dimensional stone products in limestone quarries by re …

Optimization problems are everywhere in our daily lives. When we choose the way to go to
