Personal bests as reference points [PDF]

open access: yesProceedings of the National Academy of Sciences, 2017
Personal bests act as reference points. Examining 133 million chess games, we find that players exert effort to set new personal best ratings and quit once they have done so. Although specific and difficult goals have been shown to inspire greater motivation than vague pronouncements to “do your best,” doing one’s best can be a specific and difficult ...

Contracts as Reference Points - Experimental Evidence [PDF]

open access: yesSSRN Electronic Journal, 2008
Hart and John Moore (2008) introduce new behavioral assumptions that can explain long-term contracts and the employment relation. We examine experimentally their idea that contracts serve as reference points. The evidence confirms the prediction that there is a trade-off between rigidity and flexibility.

Online Tracking of Small-Signal Stability Rightmost Eigenvalue Based on Reference Point

open access: yesIEEE Access, 2023
Machine learning technologies have been applied to improve the real-time performance of small-signal stability assessment, while achieving a high accuracy requires numerous samples, and model performance may degrade if not updated over time. Furthermore,

Fingerprint Reference Point Detection

open access: yesEURASIP Journal on Advances in Signal Processing, 2004
Summary: A robust fingerprint recognition algorithm should tolerate the rotation and translation of the fingerprint image. One popular solution is to consistently detect a unique reference point and compute a unique reference orientation for translational and rotational alignment.

An objective multi-criteria approach to optimization using MOORA method and interval grey numbers

open access: yesTechnological and Economic Development of Economy, 2012
Many real-world problems are complex and/or related to the manifestation of some form of uncertainty and/or prediction. Therefore the use of extended MCDM methods is more appropriate than the use of the other classic decision making methods.

Multicentric Atrial Strain COmparison between Two Different Modalities: MASCOT HIT Study

open access: yesDiagnostics, 2020
Two methods are currently available for left atrial (LA) strain measurement by speckle tracking echocardiography, with two different reference timings for starting the analysis: QRS (QRS-LASr) and P wave (P-LASr).
