Impact Evaluation of Innovative Selective Harmonic Mitigation Algorithm for Cascaded H-Bridge Inverter on IPMSM Drive Application
2021
This paper presents a detailed analysis of the use of a novel Harmonic Mitigation algorithm for Cascaded H-Bridge Multilevel Inverter in electrical drives for the transportation field. For this purpose, an enhanced mathematical model of Interior Permanent Magnet Synchronous Motor (IPMSM), that takes into account simultaneously saturation, cross-coupling, spatial harmonics, and iron loss effects, has been used. In detail, this model allows estimating accurately the efficiency and the torque ripple of the IPMSM, crucial parameters for transportation applications. Moreover, two traditional pulse width modulation strategies, Sinusoidal Phase-Shifted and Switching Frequency Optimal Phase-Shifted…
Prosociality and life satisfaction: A daily-diary investigation among Spanish university students
2018
Abstract With a diary study, we tested the positive effect of prosociality on life satisfaction. Fifty-six Spanish undergraduate students (45 females; Mage = 21.08 years) rated their life satisfaction, prosociality, self-esteem, and physical appearance for 5 consecutive days. Multilevel results indicated that within-individual positive deviations in prosociality (i.e., behaving more prosocial than usual) were uniquely and significantly associated with higher life satisfaction on that specific day. Students' self-esteem, physical appearance, and positive daily events were also predictive of life satisfaction. Exploratory analyses revealed that the positive effect of prosociality on life sati…
L2 or L3? Foreign Language Enjoyment and Proficiency
2017
Enjoyment is among the achievement emotions encountered in school and university settings. While often identified with a sense of belonging not necessarily connected with learning (Lumby, 2011), foreign language enjoyment (FLE) in SLA has been found to correlate with teachers’ professional and affective skills, and the existence of a supportive peer group. The risk involved with meeting the challenges of the SLA process induces both private and social feelings of FLE (Dewaele & MacIntyre, 2016). This study hypothesizes that a good command of language may be a source of elevated levels of enjoyment, because greater language proficiency is connected with greater control perception, especially…
Positive Predictive Value of Extraversion in Diagnosing L2WTC
2021
Willingness to communicate in a foreign/second language (L2 WTC) is now considered an influential variable underlying the second and foreign language learning processes. It is also perceived in terms of a fundamental goal of second language education, because its higher levels result in a greater desire to practise oral communication, bringing about successful language learning. According to the pyramid model of L2 WTC, it is rooted in personality which produces both distal and enduring influences on a student’s verbal behaviour. It can thus be expected that extraversion, a personality dimension identified with energy and enthusiasm and characterised by sensitivity to reward and sociability…
Is individual- and school-level teacher burnout reduced by proactive strategies?
2021
There is provisional evidence that burnout may be contagious within professional communities via the crossover effect, referring to an inter-individual transmission of stress or strain. However, our understanding of effective means for tackling stressors is scarce. We tested a two-level path model to explore the interrelation between teachers’ proactive self- and co-regulative strategies and experienced burnout. The study sample comprised 1531 Finnish in-service teachers from 75 schools. The results showed that burnout symptoms varied both between individual teachers and between professional communities. Self- and co-regulative strategies serve partly different functions in regulating teach…
Self-regulatory Efficacy and Foreign Language Attainment
2016
The foreign language learning process is lengthy and full of obstacles, while the most significant learning effects are quite delayed in time, and difficult to notice on a day-to-day basis. For this reason perseverance in self-controlling efforts may be of crucial importance to language success. It allows for a steady linguistic and cultural development of the student, allowing him to enjoy diverse, even contradictory opinions, leading to ultimate language success. The results of the research carried out with Polish secondary grammar school students (N = 621) demonstrate that only in reference to self-assessment of FL skills students with high levels of self-regulated efficacy significantly…
Comparing male and female students’ self-efficacy and self-regulation skills in two undergraduate mathematics course contexts
2018
International audience; Students' efficacy beliefs have a positive influence on students' academic achievement and retention, especially for female students. These beliefs are closely linked to students' ability to regulate their learning. In this quantitative study, students' self-efficacy and self-regulation of learning are compared in two university mathematics courses that differ in content but also in their pedagogical setting: one is a more traditional lecture-based course, and the other course is taught with the Extreme Apprenticeship (XA) method. The analysis is based on the same cohort of students in the two contexts (N=91). The results suggest that students have higher self-effica…
Towards Equivalence Links between Senses in PlWordNet and Princeton WordNet
2017
AbstractThe paper focuses on the issue of creating equivalence links in the domain of bilingual computational lexicography. The existing interlingual links between plWordNet and Princeton WordNet synsets (sets of synonymous lexical units – lemma and sense pairs) are re-analysed from the perspective of equivalence types as defined in traditional lexicography and translation. Special attention is paid to cognitive and translational equivalents. A proposal of mapping lexical units is presented. Three types of links are defined: super-strong equivalence, strong equivalence and weak implied equivalence. The strong equivalences have a common set of formal, semantic and usage features, with some o…
Occupation probabilities of single particle levels using the microscopic interacting boson model: Application to some nuclei of interest in neutrinol…
2016
We have developed a new method to calculate the occupancies of single particle levels in atomic nuclei. This method has been developed in the context of the microscopic interacting boson model, in which neutron and proton degrees of freedom are treated explicitly. The energies of the single particle levels constitute a very important input for the calculation of the occupancies in this method. In principle these energies can be considered as input parameters that can be fitted to reproduce the experimental occupancies. Instead of fitting, in this study we have extracted the single particle energies from experimental data on nuclei with a particle more or one particle less than a shell closu…
The role of adolescents' temperament in their positive and negative emotions as well as in psychophysiological reactions during achievement situations
2019
Abstract This study examined the role of adolescents' (n = 190) temperament in their emotional reactions in achievement situations. Adolescents rated their temperament (i.e., surgency/extraversion, negative affectivity, effortful control) and completed achievement tasks in Grade 6. They also reported their emotions before and during challenging and non-challenging tasks. In addition, adolescents' autonomic nervous system reactions (i.e., skin conductance levels) were recorded. The results showed that high effortful control was related to higher levels of positive emotions independent of the degree of task difficulty. Low negative affectivity and high effortful control were related to lower …
