Unambiguous Functions in Logarithmic Space [PDF]

open access: possibleFundamenta Informaticae, 2012
We investigate different variants of unambiguity in the context of computing multi-valued functions. We propose a modification to the standard computation models of Turing machines and configuration graphs, which allows for unambiguity-preserving composition. We define a notion of reductions (based on function composition), which allows nondeterminism

High‐performance local‐dimming algorithm based on image characteristic and logarithmic function

Journal of the Society for Information Display, 2018
With the emergence of high‐dynamic range (HDR) image and video, displaying an HDR image or video on a standard dynamic range displays with natural visual effect, clear details on local areas, and high‐contrast ratio has become an important issue.

Logarithmic Hyperbolic Cosine Adaptive Filter and Its Performance Analysis

IEEE Transactions on Systems, Man, and Cybernetics: Systems, 2021
The hyperbolic cosine function with high-order errors can be utilized to improve the accuracy of adaptive filters. However, when initial weight errors are large, the hyperbolic cosine-based adaptive filter (HCAF) may be unstable.

Logarithmic Functions and the Natural Logarithmic Function

2022
In this chapter, we will define logarithmic functions. We will then derive general properties of logarithmic functions. Then, we will define the natural logarithmic function. We will then derive general properties of the natural logarithmic function.

Logarithmic Data Processing Can Be Used Justifiably in the Plotting of a Calibration Curve.

Analytical Chemistry, 2021
The article is a response to a recent opinion piece that log concentration values should not be applied in analytical chemistry. An essential aim in the development of analytical chemistry methods is to obtain more sensitive and accurate detection values.

On Heuvers’ Logarithmic Functional Equation

Results in Mathematics, 2002
\textit{K. Heuvers} [Aequationes Math. 58, No.~3, 260--264 (1999; Zbl 0939.39016)] has shown that the solutions of the functional equation \[ f(x+y)-f(x)-f(y)=f(x^{-1}+y^{-1}) \] is equivalent to the Cauchy logarithmic functional equation \[ f(xy)=f(x)+f(y) \] when \(f\) is a function from the positive real numbers into the reals.

Exponential and Logarithmic Functions

2021
Exponential and logarithmic functions (and in general all transcendental functions) can be analyzed by developing inequalities that compare them with polynomial and rational functions. This method lies in the heart of calculus as advocated by Euler, Newton, Leibniz, the Bernoulli brothers, Taylor, and others.
