Packing a Trunk

2003

We report on a project with a German car manufacturer. The task is to compute (approximate) solutions to a specific large-scale packing problem. Given a polyhedral model of a car trunk, the aim is to pack as many identical boxes of size 4 × 2 × 1 units as possible into the interior of the trunk. This measure is important for car manufacturers, because it is a standard in the European Union.

A Note on Symmetry in Job Contact Networks

2007

Since the seminal work of Granovetter (1995), the sociological literature highlighted the importance of social relationships, like friends, relatives and acquaintances, as sources of information on jobs in labor markets. Such importance is also confirmed by a number of empirical studies.3 More recently, economists have devoted considerable attention to this topic,4 so that the study of individual and aggregate economic outcomes produced by the presence of social relationships in labor markets is becoming a fruitful research area in economics.

Communication Design for the Dissemination of Scientific Knowledge. Languages, Tools, Technologies, Collaborative Processes for Museum Education

2019

Il testo propone l’analisi di un articolato processo di ricerca-azione, avviato in occasione di alcune sperimentazioni didattico-scientifiche nate dalla collaborazione tra le discipline del design, della rappresentazione multimediale, delle scienze botaniche nell’Università di Palermo. L’esperienza proposta è stata centrata sulla comunicazione scientifica e sull’elaborazione di prodotti comunicativi per la didattica museale e istituzionale dell’Orto Botanico di Palermo. In quest’occasione sono stati sperimentati strumenti progettuali, tecnologie e modalità di espressione successivamente rielaborati anche in un progetto di sviluppo territoriale, che ha portato alla realizzazione del “Micromu…

CLIL and Literary Education: Teaching Foreign Languages and Literature from an Intercultural Perspective—The Results of a Case Study

2020

This article intends to explore the relationship between CLIL and literary education by considering the results of a case study involving the teaching of foreign literatures from an intercultural perspective in Italian secondary schools. In the first part we introduce a model of literary and intercultural communicative competence and in the second part we present a case study implemented in three secondary schools in Northern Italy. A qualitative research design was implemented and data were collected through interviews with teachers and questionnaires answered by students. The results revealed that while teachers focus on the intercultural dimension of literature only in terms of the expan…

Dimensiones y espacios electorales en las elecciones autonómicas vascas de 2012 y 2016

2018

En este artículo se analiza la incidencia de los principales cleavages –ideológico e identitario- presentes en la competición electoral vasca para las elecciones de 2012 y 2016, e intenta constituirse como una vía intermedia entre aquellos desarrollos teóricos que señalan la preeminencia de alguna de estas dimensiones de forma generalizada para todas las formaciones. Para ello abordamos los comicios a través de la teoría espacial del voto, mediante la utilización de modelos de regresión logística binaria. Esto nos ha permitido conocer el desigual peso otorgado por cada uno de los electorados de las diferentes formaciones políticos a estas fracturas centrales. Asimismo, para las elecciones d…

Attentional vs computational complexity measures in observing paintings

2009

Because of the great heterogeneity of subjects and styles, esthetic perception delineates a special and elusive field of research in vision, which represents an interesting challenge for cognitive science tools. With specific regard to the role of visual complexity, in this paper we present an experiment aimed to measure this dimension in a heterogeneous set of paintings. We compared perceived time complexity measures - based on a temporal estimation paradigm - with physical and statistical properties of the paintings, obtaining a strong correlation between psychological and computational results.

Speech Intelligibility Analysis and Approximation to Room Parameters through the Internet of Things

2021

In recent years, Wireless Acoustic Sensor Networks (WASN) have been widely applied to different acoustic fields in outdoor and indoor environments. Most of these applications are oriented to locate or identify sources and measure specific features of the environment involved. In this paper, we study the application of a WASN for room acoustic measurements. To evaluate the acoustic characteristics, a set of Raspberry Pi 3 (RPi) has been used. One is used to play different acoustic signals and four are used to record at different points in the room simultaneously. The signals are sent wirelessly to a computer connected to a server, where using MATLAB we calculate both the impulse response (IR…

Executable Data Quality Models

2017

The paper discusses an external solution for data quality management in information systems. In contradiction to traditional data quality assurance methods, the proposed approach provides the usage of a domain specific language (DSL) for description data quality models. Data quality models consists of graphical diagrams, which elements contain requirements for data object's values and procedures for data object's analysis. The DSL interpreter makes the data quality model executable therefore ensuring measurement and improving of data quality. The described approach can be applied: (1) to check the completeness, accuracy and consistency of accumulated data; (2) to support data migration in c…
