L'effetto della tessitura interna sulle preferenze cognitive
2008
In questo lavoro vengono esplorati gli effetti della tessitura interna di un'immagine sulle preferenze cognitive relative alla simmetria percepita. A questo scopo è stato preparato un test su soggetti umani basato sulla identificazione della simmetria principale in una figura geometrica al variare della sua tessitura interna, i cui esiti sono stati comparati con l'analisi effettuata da un modello di ricerca della simmetria fuzzy che incorpora elementi di preferenza ricalcati sull'esperienza umana. Dai risultati ottenuti si può vedere come, in accordo con il modello gestaltico, la preferenza cognitiva relativa alla simmetria viene influenzata anche da fattori considerati secondari come la te…
Il linguaggio informatico inglese e italiano: considerazioni su alcuni aspetti lessicali dal confronto tra le due lingue.
2005
Nel corso di quest'ultimo ventennio lo studio dei linguaggi specialistici ha ricevuto un'attenzione sempre maggiore, parallelamente alla rapida espansione della letteratura tecnico-scientifica in diversi campi del sapere. Uno degli ambiti specialistici in costante evoluzione è senza dubbio quello informatico. Proprio la terminologia connessa con lo sviluppo di questo specifico settore sarà qui assunta a oggetto di analisi e di riflessione. Più precisamente, taluni aspetti terminologici del linguaggio informatico inglese verranno messi a confronto con i corrispondenti aspetti del linguaggio informatico italiano così che emergano sia certi tratti peculiari dell'uno e dell'altro, sia rilevanti…
Modeling and designing a robotic swarm: A quantum computing approach
2023
Nature is a neverending source of inspiration for technology. Quantum physics suggests applications to- ward quantum computing. Swarms’ self-organization leads to robotic swarm developments. Here, quantum computing is applied to swarm robotics. We model local interactions with a quantum circuit, testing it on simulators and quantum computers. To relate local with global behavior, we develop a block matrix-based model. Diagonal sub-matrices contain information on single robots; off-diagonal sub-matrices are the pairwise interaction terms. Comparing different swarms means comparing different block matrices. Choosing initial values and computation rules for off-diagonal blocks (with a particul…
Novel VAMPIRE algorithms for quantitative analysis of the retinal vasculature
2013
This paper summarizes three recent, novel algorithms developed within VAMPIRE, namely optic disc and macula detection, arteryvein classification, and enhancement of binary vessel masks, and their performance assessment. VAMPIRE is an international collaboration growing a suite of software tools to allow efficient quantification of morphological properties of the retinal vasculature in large collections of fundus camera images. VAMPIRE measurements are currently mostly used in biomarker research, i.e., investigating associations between the morphology of the retinal vasculature and a number of clinical and cognitive conditions.
Some Investigations on Similarity Measures Based on Absent Words
2019
In this paper we investigate similarity measures based on minimal absent words, introduced by Chairungsee and Crochemore in [1]. They make use of a length-weighted index on a sample set corresponding to the symmetric difference M(x)ΔM(y) of the minimal absent words M(x) and M(y) of two sequences x and y, respectively. We first propose a variant of this measure by choosing as a sample set a proper subset (x, y) of M(x)ΔM(y), which appears to be more appropriate for distinguishing x and y. From the algebraic point of view, we prove that (x, y) is the base of the ideal generated by M(x)ΔM(y). We then remark that such measures are able to recognize whether the sequences x and y share a common s…

Prediction of User-Brand Associations Based on Sentiment Analysis
2023
Finding the right users to be chosen as targets for advertising campaigns is not a trivial task, and it may allow important commercial advantages. A novel approach is presented here for the recommendation of new possible consumers to brands interested in distributing advertising campaigns, ranked according to the “compatibility” between users and brands. A database containing both descriptions associated with different brands, and textual information about users' opinions on different topics, is required in input. Then, sentiment analysis techniques are applied to measure to what extent the users match with the brands, based on the texts associated with their opinions. The approach has been…
miMic
2016
miMic, a sonic analogue of paper and pencil is proposed: An augmented microphone for vocal and gestural sonic sketching. Vocalizations are classified and interpreted as instances of sound models, which the user can play with by vocal and gestural control. The physical device is based on a modified microphone, with embedded inertial sensors and buttons. Sound models can be selected by vocal imitations that are automatically classified, and each model is mapped to vocal and gestural features for real-time control. With miMic, the sound designer can explore a vast sonic space and quickly produce expressive sonic sketches, which may be turned into sound prototypes by further adjustment of model…
To embody or not to embody: A sound design dilemma
2019
Designing with sound is about constructing appropriate sound representations of a concept, from the early ideas to the final product. A survey research on embodied sound sketching is presented, and the problems of early representation in sound design are discussed by analysing the questionnaire results of three workshops on vocal sketching.
