First-year engineering students’ use of their mathematics textbook - opportunities and constraints
2012
Published version of an article in the journal: Mathematics Education Research Journal. Also available from the publlisher at: http://dx.doi.org/10.1007/s13394-012-0040-9 The role of the mathematics textbook at tertiary level has received limited exposure in previous research although it is likely that students work individually and that some of this work depends on the use of the textbook. The aim of this study was to investigate the process of approaching the textbook from epistemological, cognitive, and didactical perspectives. The focus was on identifying and discussing the opportunities and constraints in the process. The study was an explorative case study and the participants were fi…
El tratamiento integrado de lenguas en la gramática: una aproximación a la terminología básica en los libros de texto de secundaria
2021
Este artículo analiza la variación terminológica que afecta las denominaciones (variación denominativa), porque en muchas ocasiones los términos constituyen un obstáculo en la construcción de los conceptos. Concretamente, se ha desarrollado un trabajo terminográfico, de recopilación de los términos utilizados para referirse a las diferentes clases de palabras en los libros de texto de las asignaturas de Castellano y Valenciano de primero y segundo de ESO. Los resultados obtenidos muestran la gran incoherencia terminológica de los libros de texto, con un exceso de términos que dificultan el aprendizaje del alumnado, lo que pone de manifiesto la necesidad de llevar a cabo un tratamiento integ…
Normal pressures and frictional tractions on shallow conical hopper walls after concentric filling: Predictions and experiments
2013
Author's version of an article in the journal: Chemical Engineering Science. Also available from the publisher at: http://dx.doi.org/10.1016/j.ces.2012.11.028 A silo with a shallow hopper is designed to achieve the required silo capacity when the headroom available is limited, provided that the issue of segregation of stored particulate solids is not a problem. Several analytical models have been proposed to try to predict the design loads for such shallow silo hoppers to guarantee their structural integrity. In this study, a novel finite element analysis has been conducted to explore the development of pressures and tractions on the wall of a full scale shallow hopper when it is filled wit…
Positive L1 observer design for positive Switched systems
2014
Published version of an article in the journal: Circuits, Systems, and Signal Processing. Also available from the publisher at: http://dx.doi.org/10.1007/s00034-013-9737-6 This paper investigates the problem of L1 observer design for positive switched systems. Firstly, a new kind of positive L1 observer is proposed for positive switched linear delay-free systems with observable and unobservable subsystems. Based on the average dwell time approach, a sufficient condition is proposed to ensure the existence of the positive L1 observer. Under the condition obtained, the estimated error converges to zero exponentially, and the L1 -gain from the disturbance input to the estimated error is less t…

Formulaic language
2021
The notion of formulaicity has received increasing attention in disciplines and areas as diverse as linguistics, literary studies, art theory and art history. In recent years, linguistic studies of formulaicity have been flourishing and the very notion of formulaicity has been approached from various methodological and theoretical perspectives and with various purposes in mind. The linguistic approach to formulaicity is still in a state of rapid development and the objective of the current volume is to present the current explorations in the field. Papers collected in the volume make numerous suggestions for further development of the field and they are arranged into three complementary par…
Toward learning autonomous pallets by using fuzzy rules, applied in a Conwip system
2012
Published version of an article in the journal: The International Journal of Advanced Manufacturing Technology. Also available from the publisher at: http://dx.doi.org/10.1007/s00170-012-4057-8 Nowadays, material planning and control strategies are becoming continuously complex tasks spanning from individual plants to logistic networks. In fact, this is the consequence of increasing intricacy in product variants and their respective convolution in networks’ structures. Customers ask for specific products with individual characteristics that force companies for more clever performances by more flexibility. For doing so, the existing planning and control systems, which work based on central m…

Influenze tra processo ed esiti: alleanza, coesione e cambiamento in un gruppo terapeutico a lungo termine
2012
Questo lavoro esplora, in un gruppo terapeutico con pazienti gravi, due tra le variabili di processo più indagate nelle terapie di gruppo, l’alleanza terapeutica e la coesione, analizzandone le associazioni con gli esiti del trattamento in termini di sintomi e difese. E’ stato esaminato un gruppo a lungo termine, semi-aperto, a cadenza settimanale. L’osservazione si è svolta per un periodo di 18 mesi, per un totale di 50 sedute. Sono stati monitorati 11 soggetti che riportavano diverse diagnosi nell’Asse I e II del DSM IV. TR Gli strumenti di esito usati sono stati l’SCL-90: Symptom Check List; l’ OQ-45: Outcome Question-naire 45.2; e il DSQ: Defense Style Questionnaire. Mentre per rilevare…
L'interprete al cinema: stereotipi, pregiudizi e realtà
2020
The figure of the interpreter in history has always oscillated between visibility and invisibility. Although today there is a tendency to give it increasing recognition, some categories (cultural mediators, war and sign interpreters) still remain in a poorly recognized situation and often operate in precarious working conditions. The interpreter as a subject of study has been present in world literature for years. We will investigate what has become the interpreter as a subject in world cinema. What is the semiotic process for which a given image of the interpreter communicates a certain cliché or suggests certain characteristics that the director (or the screenwriter) wanted to highlight. …
