Some theorems on the explicit evaluation of Ramanujan's theta-functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2004
Bruce C. Berndt et al. and Soon-Yi Kang have proved many of Ramanujan's formulas for the explicit evaluation of the Rogers-Ramanujan continued fraction and theta-functions in terms of Weber-Ramanujan class invariants.

Liquid-Liquid Flow Pattern Prediction Using Relevant Dimensionless Parameter Groups

open access: yesEnergies, 2020
Accurate predictions of flow patterns in liquid-liquid flow are critical to the successful design and operation of industrial and geo-energy systems where two liquids are jointly transported.

Effect of retrogression re-aging treatment on corrosion behavior of 7055 Al-Zn-Mg alloy

open access: yesMaterials Research Express, 2020
The effect of retrogression re-aging treatment (RRA) on the corrosion behavior of 7055 Al-Zn-Mg alloy was studied in this paper. Results provided that corrosion resistance could be greatly improved by RRA.

Calculation efficiencies for mean numerosity [PDF]

open access: yes, 2018
Relative numerosity is traditionally studied using texture pairs. Observers must decide which member of each pair has the greater total number of texture elements.

Lyman-continuum galaxies and the escape fraction of Lyman-break galaxies [PDF]

open access: yes, 2014
Lyman break galaxies (LBGs) at z ~ 3-4 are targeted to measure the fraction of Lyman continuum (LyC) flux that escapes from high redshift galaxies. However, z ~ 3-4 LBGs are identified using the Lyman break technique which preferentially selects galaxies

Experimental Investigation on the Perturbation Length for Air–Water Flow Upstream and Downstream of U-Bends

open access: yesFrontiers in Energy Research, 2022
In this work, the perturbation length of vertical U-bend effects on the air–water two-phase flow in their adjacent straight tubes was investigated experimentally at ambient pressure and temperature.

Effects of perceptual variables on numerosity comparisonin 5-6-year-olds and adults

open access: yesFrontiers in Psychology, 2013
Although a critical issue in the debate over the existence of abstract numerical representation, it remains unclear whether and how perceptual variables affect numerosity judgment and how they change across development stages.

Dispersion kinetics in mechanically agitated vessel [PDF]

open access: yesEPJ Web of Conferences, 2019
Agitation of two immiscible liquids or solid-liquid suspension is a frequent operation in chemical and metallurgical industries. Prediction of mean drop/particle size and drop/particle size distribution (DSD) is vital for emulsification, suspension ...

Math Anxiety Mediates the Link Between Number Sense and Math Achievements in High Math Anxiety Young Adults

open access: yesFrontiers in Psychology, 2020
In the past few years, many studies have suggested that subjects with high sensory precision in the processing of non-symbolic numerical quantities (approximate number system; ANS) also have higher math abilities.

The route toward a diode-pumped 1-W erbium 3-µm fiber laser [PDF]

open access: yes, 1997
A rate-equation analysis of the erbium 3-um ZBLAN fiber laser is performed. The computer calculation includes the longitudinal spatial resolution of the host material.
