Study on modeling and production inaccuracies for artillery firing [PDF]
Archive of Mechanical Engineering, 2022 Production and assessment of artillery firing tables (FT) are the key tasks in solving ballistic problems through both standard and non-standard firing conditions. According to the literature, two different standard firing table formats were developed by

A rapidly convergent method for solving third-order polynomials
AIP Advances, 2022 We present a rapidly convergent method for solving cubic polynomial equations with real coefficients. The method is based on a power series expansion of a simplified form of Cardano’s formula using Newton’s generalized binomial theorem.
