The Management of Linguistic Data on Infrastructure Evaluation

open access: yesRevista Ingeniería de Construcción, 2000
The pavement evaluation within a transportation organisation is generally developed by experienced pavement engineers. Such technical experts use their knowledge, experience and judgment to evaluate pavement condition.

Generalized Boundary Condition Applied to Lieb-Schultz-Mattis-Type Ingappabilities and Many-Body Chern Numbers

open access: yesPhysical Review X, 2020
We introduce a new boundary condition which renders the flux-insertion argument for the Lieb-Schultz-Mattis-type theorems in two or higher dimensions free from the specific choice of system sizes.

The Cayley-Dickson Construction in ACL2 [PDF]

open access: yesElectronic Proceedings in Theoretical Computer Science, 2017
The Cayley-Dickson Construction is a generalization of the familiar construction of the complex numbers from pairs of real numbers. The complex numbers can be viewed as two-dimensional vectors equipped with a multiplication. The construction can be used

Bridge Condition Assessment Using D Numbers

open access: yesThe Scientific World Journal, 2014
Bridge condition assessment is a complex problem influenced by many factors. The uncertain environment increases more its complexity. Due to the uncertainty in the process of assessment, one of the key problems is the representation of assessment results.

Condition Numbers of the Nonlinear Matrix Equation Xp-A⁎eXA=I

open access: yesJournal of Function Spaces, 2018
We explore the condition numbers of the nonlinear matrix equation Xp-A⁎eXA=I. Explicit expressions for the normwise, mixed, and componentwise condition numbers are derived.

Numerical Stability in Complex Summation

open access: yesپژوهش‌های ریاضی, 2021
The natural and practical condition numbers for summation of complex numbers are introduced. These numbers measure the effect of loss of significant digits on the round-off error when computing a sum in floating point arithmetic. The relationship between

Data integration across conditions improves turnover number estimates and metabolic predictions

open access: yesNature Communications, 2023
The construction of protein-constrained genome-scale metabolic models depends on the integration of organism-specific enzyme turnover numbers. Here, the authors show that correction of turnover numbers by simultaneous consideration of proteomics and ...

The processing of symbolic and nonsymbolic ratios in school-age children. [PDF]

open access: yesPLoS ONE, 2013
This study tested the processing of ratios of natural numbers in school-age children. Nine- and eleven-year-olds were presented collections made up of orange and grey dots (i.e., nonsymbolic format) and fractions (i.e., symbolic format).
