On the Impact of Approximate Computation in an Analog DeSTIN Architecture
IEEE Transactions on Neural Networks and Learning Systems, 2014Deep machine learning (DML) holds the potential to revolutionize machine learning by automating rich feature extraction, which has become the primary bottleneck of human engineering in pattern recognition systems. However, the heavy computational burden renders DML systems implemented on conventional digital processors impractical for large-scale ...

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

Impact of Approximation Error on the Decisions of LDPC Decoding
Journal of Signal Processing Systems, 2010In this paper the impact of the approximation error on the decisions taken by LDPC decoders is studied. In particular, we analyze the mechanism, by means of which approximation error alters the decisions of a finite-word-length implementation of the decoding algorithm, with respect to the decisions taken by the infinite precision case, approximated ...

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.

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 ...

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 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).
