Software-Based EDF Message Scheduling on CAN Networks
2006
In this paper, a CAN-based communication system has been used to transmit data between different kinds of sensors and the drive control of an electrical vehicle. Software-based earliest deadline first (EDF) scheduling has been applied to order the data, making possible that more relevant measures meet with their delivery time and, discarding, if necessary, less relevant ones are discarded. The messages use their time-to-deadline as their priority level. With this mechanism, alongside with the discard of data that has lost its deadline, is it possible to deal with saturated that would require a bus utilization well above 100%.
Optimal deadline assignment for periodic real-time tasks in dynamic priority systems
2006
Real-time systems are often designed using a set of periodic tasks. Task periods are usually set by the system requirements, but deadlines and computation times can be modified in order to improve system performance. Sensitivity analysis in real-time systems has focused on changes in task computation times using fixed priority analysis. Only a few studies deal with the modification of deadlines in dynamic priority scheduling. The aim of this work is to provide a sensitivity analysis for task deadlines in the context of dynamic-priority, pre-emptive, uniprocessor scheduling. In this paper, we present a deadline minimisation method that achieves the maximum reduction. As undertaken in other s…
Reporte de las familias sobre los patrones de actividad física extraescolar en niñas y niños de educación infantil
2016
Early childhood education is an important opportunity in order to promote healthy habits. In doing so, it has been shown that parents attitudes, values and knowledge in relationship with physical activity could be determine children´s behaviours. For this reason, the main aim of this descriptive-exploratory study is to determine the parents perception of physical activity patterns of children between 3-4 years old from a public school of Valencia, Spain. It was used a previously validated questionnaire. Only 50% of the families reported that children participated in leisure time activities outside school. Of them, 50% and 38% participated during 2 and 1 time, respectively. 60% and 22% repor…
‘Ordinary’ and ‘diverse’ families : A case study of family discourses by Finnish early childhood education and care administrators
2021
The increased family diversity is a major global trend. Although family configurations are also diverse in contemporary Finland, it has been argued that Finnish family policies and institutional understanding of family life continues to focus on the heteronormative two-parent family with a native Finnish background. To address this issue, we analysed Finnish family discourses through qualitative interviews with early childhood education and care administrators (n = 47), applying a discourse analytic framework. Our results suggest that families are discussed through two divergent but interwoven discourses, i.e. the discourse of ordinary families and that of diverse families. The former focus…
Illustrating a Family. The Printing Press and Political Issues in the "Ritratti della Prosapia et Heroi Moncadi nella Sicilia"
2021
In an early printed book, the presence of a large iconographic apparatus normally reveals a strong effort both in designing its shape and in the financial coverage needed to make it possible. Such effort can be fully explained by paying attention to the scope and target behind its conception. The two volumes of “Ritratti della Prosapia et heroi Moncadi nella Sicilia”, published in 1657 in Valencia, offer a notable example of the political exposure sought after by a noble family, that of Moncada, through the printing press technique and its power of circulation, combined with the attractiveness of family portraits. In particular, the 1657 book, written by Giovanni Agostino Della Lengueglia, …
Founding-family-controlled firms, intergenerational succession, and firm value
2022
Using a unique, hand-collected data sample and panel-data econometric techniques, we analyse the impact of founding-family control and intergenerational succession on the value of Chilean listed companies. After controlling for firm- and ownership-specific characteristics, we find an inverse U-shaped relationship between a founding family’s degree of ownership and firm value. Hence, family ownership at first increases firm value. However, when family ownership exceeds a threshold of about 38 percent of outstanding shares, the family takes advantage of its power in the firm and extracts wealth from minority shareholders. Further, if the founder of the company is the CEO or chairman of the bo…
Différences de genre et formes de dépendances des conjoints biactifs dans l'accompagnement des enfants
2011
International audience; L'approche des différences de genre dans la mobilité a été renouvelée à partir des années 2000 par l'attention portée aux formes d'interdépendance entre conjoints pour leurs déplacements quotidiens. Dans ce travail mobilisant l'enquête ménages-déplacements d'Île-de-France, nous en avons relevé deux types à partir de l'analyse de l'accompagnement des enfants des conjoints de couples de biactifs. D'une part, il y a un effet d'entraînement. Lorsqu'un conjoint fait de l'accompagnement, l'autre a une probabilité plus forte d'en faire également. D'autre part, les conjoints se distribuent entre eux l'accompagnement avant travail et après travail. Toutefois, l'interdépendanc…
School-family relationship: a survey on the communicative and participatory methods of non-indigenous families
2022
Il complesso processo educativo basato sull’educazione delle giovani generazioni comporta un’assunzione di responsabilità da parte delle due principali agenzie educative: la famiglia e la scuola. Per la buona riuscita del processo educativo è necessario che tra le due agenzie ci sia un accordo implicito o esplicito sugli aspetti terminologici e concettuali, affinché si stabilisca una comprensione comune per gli interlocutori e si crei un contesto chiaro e trasparente che non lasci spazio a interpretazioni fallaci (Quaranta, 2019). I cambiamenti socioculturali hanno determinato un pluralismo culturale, religioso e nuove sfide tecnologiche e problematiche comunicative e partecipative (Pati, 2…
Automatic detection of thermal anomalies in induction motors
2021
The paper proposes a methodology based on Artificial Intelligence techniques for the automatic detection of abnormal thermal distributions in electric motors, to rapidly identify pre-faults or fault conditions. The proposed approach, applied to induction motors of different sizes, installed in waterworks plants, is based on the execution of Thermographic Non-Destructive Tests, which allow identifying abnormal operating conditions without interrupting the ordinary working conditions of the system. Thermographic images of induction motors are acquired at the installation site and with perspectives visible to the operator, which are sometimes partially obstructed. These thermographic images ar…
Oxide anodes in electro-organic oxidation. Oxidation of maleic addon tungsten oxide anodes
1982
The electrochemical oxidation of maleic acid on tungsten anodes has been investigated. Glyoxal and carbon dioxide were the main products together with tartaric acid and acetaldehyde. Glyoxal is also obtained as the main product from the oxidation ofd-tartaric acid. Under the same conditions succinic acid is completely oxidized to carbon dioxide and water. The anodic dissolution of tungsten and the oxidation of water to oxygen become predominant in the final stages of the electrolyses.
