“Making connections” in the mathematics courses for engineers: the example of online resources for trigonometry

2018

International audience; This paper concerns the teaching of mathematics for future engineers, focusing on the theme of trigonometry. We claim that the use of trigonometry in engineering courses requires different kinds of connections: connecting different domains, different concepts, frames and registers. We use here the concept of connectivity, developed in the frame of e-textbooks analysis, to analyse online courses for future engineers in France. We evidence that these courses propose some connections; but their connectivity is not developed enough to meet the requirements of engineering courses.

Student Partners in Task Design in a computer medium to promote Foundation students' learning of mathematics

2018

International audience; A team consisting of three mathematics education teacher-researchers, four former Foundation students (called Student Partners, SPs), and two analytic assistants worked together to produce mathematical tasks in a computer medium for the mathematical learning of current Foundation students (FSs). We have explored the collaboration between the SPs and researchers, the processes and outcomes of task design, and the contribution of the collaboration to tutorial teaching of FSs. We seek insight into the learning of all concerned of mathematics, mathematics teaching, task design and personal-professional development. The project is ongoing. Here we introduce the project an…

Riflessioni comparatistiche sulla revoca della cittadinanza per reati di terrorismo

2023

l fenomeno dei cosiddetti “foreign fighters” e il verificarsi di attacchi terroristici in alcuni paesi dell’Unione europea hanno sollevato la questione relativa alla privazione della cittadinanza come misura di contrasto e tutela della sicurezza pubblica. Questo articolo intende contribuire al dibattito sulla legittimità giuridica di tale misura, esaminando i recenti sviluppi della legislazione in materia e le sue applicazioni in Belgio, Francia, Regno Unito e Italia.

Invisible Graffiti on Your Buildings: Blind and Squaring-Proof Watermarking of Geographical Databases

2007

Due to the ease of digital copy, watermarking is crucial to protect the intellectual property of rights owners. We propose an effective watermarking method for vectorial geographical databases, with the focus on the buildings layer. Embedded watermarks survive common geographical filters, including the essential squaring and simplification transformations, as well as deliberate removal attempts, e.g. by noise addition, cropping or over-watermarking. Robustness against the squaring transformation is not adressed by existing approaches. The impact on the quality of the datasets, defined as a composition of point accuracy and angular quality, is assessed through an extensive series of experime…

Which new semantic for new shapes?

2006

There are two innovations which have drastically changed the building process: the operational continuity of the design and construction phases, and the software allowing not only the representation but also the autonomous creation of complex shapes never before thought of just because they could not be represented. This last innovation gave rise to a new design paradigm whose tools, according to their supporters, are the most advanced fields of mathematics and information science. Some ways of using these new possibilities gave rise to a radical, problematic, change in the relationship net between the designer’s intentions, the shapes through which they express them (invented or self-gener…

New Representations for Multidimensional Functions Based on Kolmogorov Superposition Theorem. Applications on Image Processing

2012

Mastering the sorting of the data in signal (nD) can lead to multiple applications like new compression, transmission, watermarking, encryption methods and even new processing methods for image. Some authors in the past decades have proposed to use these approaches for image compression, indexing, median filtering, mathematical morphology, encryption. A mathematical rigorous way for doing such a study has been introduced by Andrei Nikolaievitch Kolmogorov (1903-1987) in 1957 and recent results have provided constructive ways and practical algorithms for implementing the Kolmogorov theorem. We propose in this paper to present those algorithms and some preliminary results obtained by our team…

Optimal Resource Discovery Paths of Gnutella2

2008

This paper shows that the performance of peer-to-peer resource discovery algorithms is upper bounded by a k-Steiner minimum tree and proposes an algorithm locating near-optimal query paths for the peer-to-peer resource discovery problem. Global knowledge of the topology and the resources from the peer-to-peer network are required as an input to the algorithm. The algorithm provides an objective measure for defining how good local search algorithms are. The performance is evaluated in simulated peer-to-peer scenarios and in the measured Gnutella2 P2P network topology with four local search algorithms: breadth-first search, self-avoiding random walker, highest degree search and Dynamic Query …

Grounded Analytic Research: Building Theory from a Body of Research

2012

Track II: Recent Developments in Inductive Research Methods; International audience; In this paper, we present Grounded Analytic Research (GAR) as a method to build theory by synthesizing empirical findings from multiple studies that has been conducted by a single researcher. GAR incorporates concepts from grounded theory, analytic research and systematic literature review. The method was applied in a doctoral dissertation work to build the theoretical concept of Demand Sustainability of public Internet access in the context of bridging the digital divide. We describe GAR and compare it with existing theory building methods that are similar to it in epistemology and ontology.

Pricing of digital services as an effectual co-creative process

2022

Entrepreneurs have to price their innovations under the unpredictability of customers’ reactions. While predictive pricing methods are prevalent in business-to-business pricing literature, we argue for the critical importance of control-oriented pricing strategies for digital services. By applying effectuation theory, our study investigates how entrepreneurs co-create their pricing strategies for their digital services as a co-evolutionary, iterative process with their customers. We found that pricing is the co-evolutionary process where entrepreneurs learn from their interactions with customers and use this knowledge to develop and improve their pricing practices further. The findings cont…
