We study structural, electronic, and energy properties of pure zirconium with isolated vacancies and their clusters. We discuss the lattice constant change in pure zirconium with different concentrations of isolated vacancy ...

The grindability of titanium alloys that are classified as hard-to-machine materials is studied in high-speed cylindrical grinding using a cubic boron nitride (CBN) wheel. The investigation is concerned with residual surface ...

By using the limiting case of Watson’s q-Whipple transformation as n → ∞, we investigate the transformations of the nonterminating q-Kampé-de-Fériet series. Further, new formulas for the transformations and well-posed ...
