Information Extraction from Binary Skill Assessment Data with Machine Learning

2021

Strength training exercises are essential for rehabilitation, improving our health as well as in sports. For optimal and safe training, educators and trainers in the industry should comprehend exercise form or technique. Currently, there is a lack of tools measuring in-depth skills of strength training experts. In this study, we investigate how data mining methods can be used to identify novel and useful skill patterns from a binary multiple choice questionnaire test designed to measure the knowledge level of strength training experts. A skill test assessing exercise technique expertise and comprehension was answered by 507 fitness professionals with varying backgrounds. A triangulated appr…

Continuous models combining slacks-based measures of efficiency and super-efficiency

2022

AbstractIn the framework of data envelopment analysis (DEA), Tone (Eur J Oper Res 130(3):498–509, 2001) introduced the slacks-based measure (SBM) of efficiency, which is a nonradial model that incorporates all the slacks of the evaluated decision-making units (DMUs) into their efficiency scores, unlike classical radial efficiency models. Next, Tone (Eur J Oper Res 143(1):32–41, 2002) developed the SBM super-efficiency model in order to differentiate and rank efficient DMUs, whose SBM efficiency scores are always 1. However, as pointed out by Chen (Eur J Oper Res 226(2):258–267, 2013), some interpretation problems arise when the so-called super-efficiency projections are weakly efficient, le…

Common functional component modelling

2005

Functional data analysis (FDA) has become a popular technique in applied statistics. In particular, this methodology has received considerable attention in recent studies in empirical finance. In this talk we discuss selected topics of functional principal components analysis that are motivated by financial data.

Explaining Causes Behind SQL Query Formulation Errors

2020

This Full Research Paper presents the most prominent query formulation errors in Structured Query Language (SQL), and maps these errors to their cognitive explanations. Understanding query formulation errors is a key to teaching SQL. more effectively. However, studies on what kind of errors novices struggle with are relatively scarce when compared to, for example, programming languages. Although committing errors is a crucial part in learning, some errors are relatively easy to fix, and their commonness is not necessarily an indication of their difficulty. Other errors, however, halt the learning process, and are never fixed by the query writer. Using a previously established error taxonomy…

α-decay spectroscopy of the N = 130 isotones 218Ra and 220Th: Mitigation of α-particle energy summing with implanted nuclei

2019

An analysis technique has been developed in order to mitigate energy summing due to sequential short-lived α decays from nuclei implanted into a silicon detector. Using this technique, α-decay spectroscopy of the N=130 isotones 218Ra (Z=88) and 220Th (Z=90) has been performed. The energies of the α particles emitted in the 218Ra→214Rn and 220Th→216Ra ground-state-to-ground-state decays have been measured to be 8381(4) keV and 8818(13) keV, respectively. The half-lives of the ground states of 218Ra and 220Th have been measured to be 25.99(10) μs and 10.4(4) μs, respectively. The half-lives of the ground states of the α-decay daughters, 214Rn and 216Ra, have been measured to be 259(3) ns and …

“NUMMI DIGITALI”: approcci innovativi per la conoscenza, gestione e valorizzazione del patrimonio numismatico del Museo Archeologico Regionale “A. Sa…

2022

The subject of the contribution is the “NUMMI DIGITALI” project which aims to enhance the numismatic collection of the Archaeological Museum “A. Salinas” in Palermo, closed to public use for over seventy years, which will become accessible thanks to the close interrelationship between numismatic-archaeological methodologies and the IT approach. The project, curated by Lavinia Sole, Numismatics researcher at the Culture and Society Department of the University of Palermo, within the PON "Research and Innovation" 2014-2020, Axis IV-Action IV.4, provides for the creation of a digital database, in line with the standards and cataloging tools of the ICCD and with the methodological guidelines of…

Nutrient sensing: What can we learn from different tastes about the nutrient contents in today's foods?

2019

Abstract Tastes are often described as having a nutrient-signaling function eliciting expectations about the food and its nutrient content. The objectives of this work was to investigate correlations between taste intensity and nutrient content, to evaluate the impact of competing tastes on these relationships, and to know if the content in certain nutrients could be inferred from a combination of tastes. The Food Taste Database (Martin et al., 2014) and a French Food Composition table (ANSES-Ciqual) were used to obtain a dataset combining sensory and nutritional information for 365 foods. Our results confirm the existence of several taste-nutrient relationships previously suggested by othe…

La tecnologia dell'Informazione per la gestione e la comunicazione di musei e collezioni: i metadata

2011

In una realtà come quella museale il concetto di informazione perimetra un ampio spettro di attività comela comunicazione scritta, quella verbale, quella che avviene via e-mail, il patrimonio in termini di opere e conoscenza delle stesse, tutti elementi che possono contribuire a creare confusione. In realtà, accogliendo la visionedi Checkland e Howell, l’informazione è parte di un ciclo che partendo dai dati passa attraverso l’informazione stessa per arrivare alla conoscenza. (...)

OPTEER, un dispositif de connaissance et d’analyse territoriale par et pour les acteurs de la transition énergétique

2018

International audience; The aim of this article is to illustrate, through the implementation and exploitation of the OPTEER platform (Territorial Energy Observation and Prospective at the Regional scale), how the various tools made available to territorial actors and what collective uses of geographic information have developed. Based on his experience of more than 10 years, around which crystallized operational developments and research experiments, are also evoked the new needs related to the requirements of the implementation of energy transition and the tracks of research,development and porting envisaged to guarantee the durability of the device.; Cet article a pour objectif d’illustre…
