Approximation et existence en vibro-impact
Comptes Rendus de l'Académie des Sciences - Series I - Mathematics, 1999Summary: We consider a dynamical system with a finite number of degrees of freedom, in generalized coordinates, subject to unilateral constraints, which are smooth, but not necessarily convex. When the constraints are saturated, we define an impact law involving a restitution coefficient \(e\in[0,1]\).

School markets: The impact of information approximating schools' effectiveness [PDF]
Journal of Development Economics, 2013 Abstract The impact of competition on school performance is likely to depend on whether parents are informed about schools' effectiveness or value added (which may or may not be correlated with absolute measures of their quality), and on whether this information influences their school choices, thereby affecting schools' market outcomes.

Classical Approximation for Ionization by Proton Impact
Physical Review, 1968Ionization of atoms by proton impact, as predicted by the classical binary-encounter approximation, is examined and compared with available experimental data on the noble-gas and alkali-metal atoms. The results indicate that these predictions agree with observation to within a factor of 2 or 3, and are as reliable as the comparable results for electron

Improved Approximations for a Beam Impacting a Stop
Journal of Sound and Vibration, 1994Abstract Illustrative comparisons are given of several numerical procedures for finding the contact forces and their peak values when an elastic beam collides repeatedly with a resilient stop. Computational efficiency is shown to depend upon the variable of interest.

Impact of Memory Approximation on Energy Efficiency
2018 Symposium on High Performance Computing Systems (WSCAD), 2018Approximate memories can lower energy consumption at expense of incurring errors in some of the read/write operations. While these errors may be tolerated in some cases, in general, parts of the application must be re-executed to achieve usable results when a large number of errors occur.
