A new quasi-static multi-degree of freedom tapered roller bearing model to accurately consider non-Hertzian contact pressures in time-domain simulati…
2014
The accuracy of the fatigue life calculations in rolling bearing simulations is highly dependent on the precision of the roller-raceway contact simulations and the ability to accurately include structural deflections of the supporting structure. Several different methods exist to simulate the pressure distributions, and in time-domain bearing simulations, where many contacts need evaluation, the simple and time efficient methods are more popular. These methods underestimate the fatigue life reduction due to roller end effects, overload and misalignments. Furthermore, existing time-domain rolling bearing models assume that the bearing rings remain circular, which can be a poor approximation…
Modal Analysis of Multi-Degrees-of-Freedom Systems with Singular Matrices: Analytical Dynamics Approach
2017
Complex mechanical (e.g., multibody) systems with different types of constraints are generally performed through analytical dynamics methods. In some cases, however, it is possible that the (augmented) mass and/or stiffness matrices may derive to be singular; consequently, modal analysis, which is used extensively in the classical dynamics literature, fails. In this paper, if the uniqueness condition is satisfied by the constraints, a properly modified modal analysis is elucidated into analytical dynamics leading to the evaluation of the natural frequencies in a simple and straightforward way. Under that framework, advances of both classical and analytical dynamics are taken into considerat…
Velocity sensorless control of a PMSM actuator directly driven an uncertain two-mass system using RKF tuned with an evolutionary algorithm
2010
This paper proposes a solution to tune an observer keeping robust closed loop performances for the sensorless motion control of an uncertain mechanical load directly driven by a PMSM through a flexible axis. An evolutionary algorithm optimizes the observers degrees of freedom. Experiments show that performances are effectively maintained.
In tema di proprietà: il modello romano nella tradizione giuridica
2021
We are back to discuss ownership. In fact, beyond all possible predictions, the history of property law is combined with that of fundamental human rights. The individual perspective of absoluteness, present in the codicistic tradition, the predominantly economic content of the property right, governed by the Constitution, are today deeply intertwined with the perspective of the protection and enhancement of the subject who owns it, in accordance with the provisions of the European Convention for the Protection of Human Rights and Fundamental Freedoms (ECHR) and the Charter of Fundamental Rights of the European Union (Charter of Nice). . This new perspective of protection is associated with …
Five Years of the Citizens Directive in the UK - Part 1
2011
This two-part article reviews how the UK authorities have fared in the practical application of Directive 2004/38/EC in the five years since it entered into force. It identifies and examines the most common problems faced by EU citizens when seeking to have their rights recognised by the UK authorities applying the Immigration (European Economic Area) Regulations 2006 by reference to questions and complaints received by Your Europe Advice. In examining the experience of EU citizens and their family members living in the UK, account is taken of a number of recent judgments of the European Court of Justice concerning EU citizenship, including Metock, Lassal, Eman & Sevinger and Ruiz Zambrano.…
LA ORDEN EUROPEA DE INVESTIGACIÓN COMO INSTRUMENTO PARA LA LUCHA CONTRA LA CRIMINALIDAD ORGANIZADA. Significado, sujetos y herramientas en la obtenci…
2022
The study focuses on the analysis and investigation of the European instrument called the European Investigation Order (EIO), and its contributions to the fight against organised crime. This instrument was adopted by the European legislator, with the aim of achieving effective and swift cross-border judicial cooperation in criminal matters. In this context the main question that encourages research is: to what extent is the EIO a suitable instrument in the fight against organised crime? From this question the rest of the questions arise, articulating the structure of the thesis. In addition, in this work, we highlight the comparative perspective: the EIO instrument has been examined from a …
Spain: Conviviality, Social Relationships and Democracy at the Basis of Spanish Sports Clubs’ Culture
2020
This chapter provides an overview of the main functions of sports clubs in Spanish society with regard to social integration, democratic involvement and voluntary work. At the European level, Spanish sports clubs are among the front-runners in terms of presence of people with disabilities, at the average when it comes to people with migrant background and far below the average concerning people over 65 years old and women. Talking about democratic involvement and engagement for the community, most of the clubs try to involve members when making important decisions and delegate decision-making from the board to their committees. On the other hand, their members report the democratic culture …

This research work adresses the prediction of success after a training scheme (success in university examination, integration of job seekers after a training session) on the basis of 1/ subjective indicators at the end of training: satisfaction or subjective learning and 2/ individuals' variables (self-efficacy, locus of control, self-esteem, optimism and core self-evaluation). Our results show that, compared to training evaluation models, subjective indicators at the end of training do not appear to be good predictors of success. In addition, if individuals' variables are sometimes predictable of success, this seems to be related to the mere fact that they represent high values in students…
PROVA TECNICA E CONTRADDITTORIO NEL PROCESSO PENALE
2023
When science and the criminal process come into contact, cognitive mechanisms are set in motion aimed at reorganizing knowledge belonging to worlds other than the legal one. In this context, the actors of the trial scene are forced to move on a hybrid terrain in which judicial epistemology and scientific epistemology mix. Such a fascinating picture pushes the scholar of the criminal process to seek interpretations suitable for explaining the multiple dilemmas that the phenomenon entails. Starting from a historical-legislative excursus of the expert evidence, the proposed analysis examines the different channels through which expert knowledge enters the process, starting from the investigati…
