Prospects and Design Insights of Neat Ionic Liquids as Supercapacitor Electrolytes [PDF]

open access: yesFrontiers in Energy Research, 2021
Ionic liquids present an opportunity to design efficient electrolytes for supercapacitors, which are among the most extensively studied electrochemical energy storage systems. Ionic liquids are promising candidates for supercapacitor electrolytes because

Developing non-exercise activity thermogenesis (NEAT) through building design [PDF]

open access: yesFacilities, 2022
Purpose Physical inactivity has a considerable negative impact on health. Physical activity has reduced partly due to workplace and lifestyle changes, causing people to spend more time in buildings and increasing sedentary behaviour. The purpose of this paper is to address a largely untapped opportunity for designers and managers to improve building ...

Comparison of Kernel equating methods under NEAT and NEC designs

open access: yesInternational Journal of Assessment Tools in Education, 2023
In this study, Kernel test equating methods were compared under NEAT and NEC designs. In NEAT design, Kernel post-stratification and chain equating methods taking into account optimal and large bandwidths were compared.

Calculating Bias in Test Score Equating in a NEAT Design. [PDF]

open access: yesAppl Psychol Meas
Test score equating is used to make scores from different test forms comparable, even when groups differ in ability. In practice, the non-equivalent group with anchor test (NEAT) design is commonly used. The overall aim was to compare the amount of bias under different conditions when using either chained equating or frequency estimation with five ...

Empirical Ensemble Equating Under the NEAT Design Inspired by Machine Learning Ideology

open access: yesMethodology, 2023
This study proposes an empirical ensemble equating (3E) approach that collectively selects, adopts, weighs, and combines outputs from different sources to take and combine advantage of equating techniques in various score intervals. The ensemble idea was

Outlier Detection Using t-test in Rasch IRT Equating under NEAT Design. [PDF]

open access: yesAppl Psychol Meas, 2023
In equating practice, the existence of outliers in the anchor items may deteriorate the equating accuracy and threaten the validity of test scores. Therefore, stability of the anchor item performance should be evaluated before conducting equating. This study used simulation to investigate the performance of the t-test method in detecting outliers and ...

THE MISSING DATA ASSUMPTIONS OF THE NONEQUIVALENT GROUPS WITH ANCHOR TEST (NEAT) DESIGN AND THEIR IMPLICATIONS FOR TEST EQUATING [PDF]

open access: yesETS Research Report Series, 2009
ABSTRACTThe nonequivalent groups with anchor test (NEAT) design involves missing data that are missing by design. Three popular equating methods that can be used with a NEAT design are the poststratification equating method, the chain equipercentile equating method, and the item‐response‐theory observed‐score‐equating method.
