The European Space of Higher Education convergence has stressed the importance of a potentially systemic shift in paradigms, away from what has been labelled the "instruction paradigm" towards the "learning paradigm", i.e. shifting the interest from the teacher to the student, thus leading to pedagogical implications which imply that teachers reflect upon their methodologies of teaching, evalua...

An approach to the construction of digital twins technological system for turning low rigidity parts and assessment energy state is proposed in this article. The creating twin models by differential equations allows excide a time-consuming procedure training neural networks. results obtained are transmitted block. Calculations performed determine power consumption between moving machine cutting...

This paper describes the orthodontic treatment of two cases that were successfully entered for the 2009 MOrth Cases Prize. The first case describes the treatment of a class II division 1 malocclusion with increased vertical proportions that was treated with upper and lower self-ligating appliances and headgear for anchorage support. The second case describes the use of a Clark Twin-Block applia...

The aim of this study was to evaluate the effectiveness of a fixed Twin-block appliance by using a study with a prospective cohort design. Thirty-two children were included in the study over a 2-year period. Cephalometric data were analyzed with the Pancherz cephalometric analysis. Study models were analyzed with the PAR index, and the treatment processes were recorded from the patients' record...

In the last twenty years, many algorithms and heuristics were developed to find solutions in constraint networks. Their number increased to such an extent that it quickly became necessary to compare their performances in order to propose a small number of “good” methods. These comparisons often led us to consider FC or FC-CBJ associated with a “minimum domain” variable ordering heuristic as the...

A combined application of independent component analysis and projective filtering of the time-aligned ECG beats is proposed to solve the problem of fetal ECG extraction from multi-channel maternal abdominal electric signals. The developed method is employed to process the four-channel abdominal signals recorded during twin pregnancy. The signals are complicated mixtures of the maternal ECG, the...

We used quantitative genetics techniques to compare the entrepreneurial activity of 870 pairs of monozygotic (MZ) and 857 pairs of same-sex dizygotic (DZ) twins from the United Kingdom. We ran model-fitting analyses to estimate the genetic, shared environmental and nonshared environmental effects on the propensity of people to become entrepreneurs. We found relatively high heritabilities for en...

This study investigated the influence of genetic factor and personality on leadership role occupancy among a sample of male twins. Identical twins (n =238) who share 100% of their genetic background were compared with fraternal twins (n =188) who are expected to share only 50% of their genetic background. Results indicated that 30% of the variance in leadership role occupancy could be accounted...
