On Impact Ionization of Ions Modeling in the Distorted Waves Approximation
Mathematical Models and Computer Simulations, 2022Summary: Atomic and ion properties calculated in the Hartree-Fock-Slater quantum-statistical model are used in the direct calculation of the differential and total cross sections of electron impact ionization of singly ionized oxygen and nitrogen atoms by the distorted wave approximation.

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.

An Approximate Theory of Lateral Impact on Beams
Journal of Applied Mechanics, 1955Abstract The approximate theory derived in this paper describes, by means of a “traveling-wave” approach, the behavior of beams under transverse impact. Lateral impact is considered in detail, namely, one in which a section of the beam undergoes a sudden change in velocity or shear force.

Impact of Software Approximations on the Resiliency of a Video Summarization System
2018 48th Annual IEEE/IFIP International Conference on Dependable Systems and Networks (DSN), 2018In this work, we examine the resiliency of a state-of-the-art end-to-end video summarization (VS) application that serves as a representative emerging workload in the domain of real time edge computing. The VS application constitutes key video and image analytic elements that are processed by embedded systems aboard unmanned aerial vehicles (UAVs ...

Mapping the impact of approximate gradient nonlinearity fields correction on tractography
Medical Imaging 2023: Image Processing, 2023Nonlinear gradients impact diffusion weighted MRI by introducing spatial variation in estimated diffusion tensors. Recent studies have shown that increasing signal-to-noise ratios and the use of ultra-strong gradients may lead to clinically significant impacts on analyses due to these nonlinear gradients in microstructural measures.

Impact of the Born-Oppenheimer Approximation on Aerothermodynamics
Journal of Thermophysics and Heat Transfer, 2007The Born-Oppenheimer approximation is a mathematical method in quantum mechanics describing quantification and allocation of the energy associated with molecular internal structure. The macroscopic extrapolation to gas mixtures of the microscopic characterization ensuing from the Born-Oppenheimer approximation consists of the typical energy separation ...

European physics impact – to a first approximation
Physics World, 2013Physics-based industries contributed around 14%, or €3800bn, to the total value of the European economy in 2010 – exceeding that of the construction and retail sectors combined – according to a report by the European Physical Society (EPS).

Adiabatic approximation on the impact-parameter model
Few-Body Systems, 1991In this paper we study the impact-parameter model for the scattering of a light particle by two heavy ones in the case when the coupling constants of the potentials acting on the light particle due to the presence of the two heavy ones are the same. We study the asymptotic behavior of the transition probability when the relative velocity of the heavy ...

Impact of local approximations on MP2 vibrational frequencies
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 1999Abstract Equilibrium structures and harmonic vibrational frequencies have been computed using local and conventional second-order Moller–Plesset perturbation theory (MP2) for 16 small and medium size molecules (up to 14 atoms). It is found that the deviations caused by the local approximation are usually negligible, and that the quality of the ...
