A Rule-Based System for Hardware Configuration and Programming of IoT Devices
2019
Simplifying programming, deployment, and configuration of heterogeneous networked IoT devices requires networking, hardware, representation of knowledge and concepts, design and programming skills. In fact, IoT applications are mostly built by adopting different existing paradigms and technologies on a case-by-case basis. As a result, programming tools hinder adaptability and interoperability of applications with their rigidity. In this paper, we propose a rule-based system that configures and programs IoT devices automatically. The rule base holds formal specifications about hardware platforms, networking protocols, physical world concepts, and applications. Provided with a high-level appl…
Symbolic Reductionist Model for Program Comprehension
2007
This article presents the main features of a novel construction, symbolic analysis, for automatic source code processing. The method is superior to the known methods, because it uses a semiotic, interpretative approach. Its most important processes and characteristics are considered here. We describe symbolic information retrieval and the process of analysis in which it can be used in order to obtain pragmatic information. This, in turn, is useful in understanding a current Java program version when developing a new version.
Programming languages and dynamic instructional tools: Addressing students’ knowledge base
1992
The chapter presents an instructional computer environment to be used in introductory Pascal programming classes. Traditional programming courses do not foster the kind of knowledge structures that are the trademark of expert programmers. These knowledge structures or programming templates provide programmers with a ready-to-use library of routines from which they draw when writing a new program. Developed as a hypertext tool, TAP (Template Assisted Programming) is an instructional environment to teach programming that emphasizes the development and use of such a library of routines by presenting students with a multiple representation of programming knowledge. In TAP students can (a) switc…
L’erraticità della centralità. Valori simbolici e valori monetari nella città di Palermo
2017
The center of the city could be considered as the urban meta-sign from which each part of the city takes his urban monetary significance, and it can also be joined to the isomorphic chain linking Zero, Vanishing Point and Money. The center of the city is naturally erratic and follows the urban transformation, producing monetary differentials corresponding to differentials of quality of the localization. The case study of Palermo is analyzed showing the creation of the center of the city, its translation and its (monetary) evaluation in the contemporaneous city.
epiModel: A system to build automatically systems of differential equations of compartmental type-epidemiological models
2011
In this paper we describe epiModel, a code developed in Mathematica that facilitates the building of systems of differential equations corresponding to type-epidemiological linear or quadratic models whose characteristics are defined in text files following an easy syntax. It includes the possibility of obtaining the equations of models involving age and/or sex groups. © 2011.
I sapori dei tatuaggi nell'Amazzonia indigena
2018
Through an analysis of some ethnographic examples (Matis, Akawaio,Guayaki, Cayabi), the chapter shows how in Indigenous Amazonia tattooing was connected in multiple ways to cultural conceptions regarding both the fabrication of the person and the classifications of world components, in which complex systems of correspondence between diverse domains organize people's experience and thought.
First-year university students making sense of symbols in integration
2020
International audience; This paper focuses on first year university engineering students and their sensemaking of integration and its symbolism. Through a semiotic approach, attention is given to two students and their attempt to verbally express their reflections on integration and the related meaning of symbols. Findings suggest that students tend to interpret the symbols mainly as operations, in terms of calculations to be carried out. They express uncertainty concerning what the symbols stand for, and the mathematical objects they represent. For example, the symbols ∫ and are respectively conceived of as “finding the integral with respect to x” and students are unclear on how Riemann su…
On the side of the marginals: the character of Ahmed in The Tower of Defense (1978) of Copy
2018
Copi, writer, playwright and draughtsman Ar- gentino settles in Paris in 1962 until his death in 1987. The experience of exile and wandering marks the personal and creative trajectory of this intercultural artist. Indeed, a whole series of vulnerable and marginal characters swarm in their particular universe and subvesivo. In this space of the excluded, the figure of the immi- grant Maghreb in France, embodied in the cha- racter of Ahmed, acquires all its significance. In this work we will try to analyse the symbolic value of Ahmed, heir to the colonial past mar- ked by rejection, which appears in the Teatro de Copi, specifically in La Défense Tour (1978). Ahmed’s image traces an invisible …
Ultreya, suseya, Santiago!” Viaggio e spazialità ne La ballata dei pellegrini
2020
Per studiare dal punto di vista della geografia culturale alcuni aspetti del pellegrinaggio a Santiago de Compostela, in Spagna, il capitolo prende in considerazione un testo letterario, il romanzo autobiografico "La ballata dei pellegrini" della scrittrice francese Edith De La Héronnière, pubblicato per la prima volta nel 1993 e tradotto in italiano nel 2004. Il romanzo racconta l’esperienza del pellegrinaggio giacobeo effettuato dall’autrice negli anni Novanta assieme a tre compagni di viaggio partendo da un cammino francese. In particolare, attraverso l’analisi di alcune parti del testo, si indagano le modalità attraverso le quali la narrazione costruisce e descrive lo spazio fisico e si…
Spazio, potere e memoria: riflessioni di un geografo su fumetto e cartoon di propaganda
2020
Il contributo discute criticamente e da una prospettiva geografica il nesso tra propaganda, fumetti e cartoons nel periodo dei totalitarismi novecenteschi. Viene quindi esplorato il modo in cui lo spazio, reale e simbolico, sia implicato attraverso le retoriche e le dialettiche del potere, nelle dinamiche sociali, economiche e identitarie.
