Improved Bethe approximation for electron-ion impact ionization
Physics Letters A, 1977Abstract A simple modification of the Bethe approximation is considered for collisional ionization of ionic targets by electrons at intermediate energies.

Remarks concerning impact-parameter dependent binary encounter approximation
Physics Letters A, 1976Abstract It is pointed out that the velocity of target electron as a function of it's position from the nucleus needed in the impact-parameter version of binary encounter theory of ionization can be obtained from statistical arguments.

Longitudinal Impact on Viscoplastic Rods—Approximate Methods and Comparisons
Journal of Applied Mechanics, 1964Impact is considered on a rod of finite length whose material exhibits viscoplastic behavior described by a power-law relation between strain rate and dynamic overstress. Strain-hardening and elastic strains are neglected. Solutions previously obtained for the linear case are supplemented by deriving upper and lower bounds for the final strain.

Impact of the Radon–Nikodým property on convex approximation properties
Archiv der Mathematik, 2015A classical result, essentially due to \textit{A. Grothendieck} [``Produits tensoriels topologiques et espaces nucléaires'', Mem. Am. Math. Soc. 16 (1955; Zbl 0123.30301)], states that the approximation property (AP) of a dual space \(X^*\) is metric whenever \(X^*\) or \(X^{**}\) has the Radon-Nikodým property (RNP).

Prediction of Projectile Impact Point using Approximate Statistical Moments
2018 Annual American Control Conference (ACC), 2018In this paper, trajectory and hit point prediction of a projectile is studied. Projectiles are subject to environmental noise such as wind effect and measurement noise. In addition, mathematical models of projectiles contain a large number of important states that should be taken into account for having a realistic prediction.

Impact approximation for line shape in the microwave region
Il Nuovo Cimento, 1964A quantum-mechanical ≪impact approximation≫ theory is developed for the shape of spectral lines in the microwave region, in the limiting case of high temperatures and low pressures. Effects of the internal structure of the molecules and of their identity are taken into account. Possible correlations in successive collisions are discussed.

Hybrid Program Dependence Approximation for Effective Dynamic Impact Prediction
IEEE Transactions on Software Engineering, 2018Impact analysis determines the effects that program entities of interest, or changes to them, may have on the rest of the program for software measurement, maintenance, and evolution tasks. Dynamic impact analysis could be one major approach to impact analysis that computes smaller impact sets than static alternatives for concrete sets of executions ...
