Accuracies of discriminant function equations for sex estimation using long bones of upper extremities
( Springer , 2020 , Article)© 2020, Springer-Verlag GmbH Germany, part of Springer Nature. One of the scopes of practice of forensic anthropologists is the estimation of sex from skeletal remains. As a result, population-specific discriminant function ... -
Accuracy and Coverage Assessment of House units Frame ,using Post-Frame update survey (PFS) Method
( The Social and Economic Survey Research Institute, Qatar University , 2015 , Conference Paper & Presentation)Basically, the PFS is an independent survey that repeats frame update. The survey results are compared with house units frame results, permitting estimates to be made of : coverage and content errors. Coverage errors ... -
Accuracy of artificial intelligence-assisted detection of Oral Squamous Cell Carcinoma: A systematic review and meta-analysis
( Elsevier , 2022 , Article)Oral Squamous Cell Carcinoma (OSCC) is an aggressive tumor with a poor prognosis. Accurate and timely diagnosis is therefore essential for reducing the burden of advanced disease and improving outcomes. In this meta-analysis, ... -
Accuracy of force measurement via motion analysis system in artistic gymnastics [Precisione della misurazione della forza mediante il sistema di analisi del movimento nella ginnastica artistica]
( Edizioni Minerva Medica , 2018 , Article)BACKGROUND: The aim of this study was to validate the accuracy of ground-reaction force measurement using inverse body dynamic analysis via video motion analysis system versus portable force-plate direct measurement system ... -
Accuracy of procalcitonin for diagnosing sepsis in adult patients admitted to the emergency department: a systematic review and meta-analysis
( BioMed Central Ltd , 2024 , Article Review)Background Differentiating sepsis from non-infectious systemic inflammatory response syndrome (SIRS) is challenging. Biomarkers like procalcitonin (PCT) aid early risk assessment and guide antibiotic use. This study aims ... -
Accuracy of the American Association of Endodontists diagnostic criteria for assessing pulp health in primary teeth
( Springer Science and Business Media Deutschland GmbH , 2023 , Article)Objectives There is a lack of studies evaluating the accuracy of the 2009 American Association of Endodontists (AAE) diagnostic criteria for diagnosing pulpal health in primary teeth. This study aimed to estimate and ... -
The accuracy of the anatomical method for stature estimation in Black South African females
( Elsevier , 2017 , Article)The anatomical method is considered the most accurate stature estimation method, but investigation has shown that it continuously underestimates stature. This underestimation is believed to be related to the use of universal ... -
Accurate and efficient implementation of the time–frequency matched filter
( Institution of Engineering and Technology , 2010 , Article)The discrete time-frequency matched filter should replicate the continuoustime-frequency matched filter, but the methods differ. To avoid aliasing, thediscrete method transforms the real-valued signal to the complex-valued ... -
