Temporal Denoising of Kinect Depth Data
2012
The release of the Microsoft Kinect has attracted the attention of researchers in a variety of computer science domains. Even though this device is still relatively new, its recent applications have shown some promising results in terms of replacing current conventional methods like the stereo-camera for robotics navigation, multi-camera system for motion detection and laser scanner for 3D reconstruction. While most work around the Kinect is on how to take full advantage of its capabilities, so far only a few studies have been carried out on the limitations of this device and fewer that provide solutions to enhance the precision of its measurements. In this paper, we review and analyse curr…
Wireless Sensor Network Operating System Design Rules Based on Real-World Deployment Survey
2013
Wireless sensor networks (WSNs) have been a widely researched field since the beginning of the 21st century. The field is already maturing, and TinyOS has established itself as the de facto standard WSN Operating System (OS). However, the WSN researcher community is still active in building more flexible, efficient and user-friendly WSN operating systems. Often, WSN OS design is based either on practical requirements of a particular research project or research group's needs or on theoretical assumptions spread in the WSN community. The goal of this paper is to propose WSN OS design rules that are based on a thorough survey of 40 WSN deployments. The survey unveils trends of WSN applic…
Innovare la didattica all’Università: uno strumento di riflessione per i docenti
2020
Per realizzare una didattica universitaria efficace sono necessarie alcune caratteristiche personali del docente come l’impegno, la motivazione e la conoscenza di metodologie e strumenti di valutazione adeguati. Riteniamo che per avviare la formazione dei docenti universitari sia necessario avere un quadro chiaro delle loro conoscenze didattiche e docimologiche. In questa ricerca presentiamo uno strumento che abbiamo sottoposto inizialmente a 30 docenti universitari di area pedagogico- didattica di vari atenei italiani e che successivamente, tenendo conto dei suggerimenti ricevuti, abbiamo somministrato ad un campione di 311 docenti dell’Ateneo Palermitano di tutti i dipartimenti e di quasi…
Laboratorio di Statistica Economica con R
2009
Questo libro costituisce materiale di supporto ed integrazione alle lezioni di LABORATORIO DI STATISTICA ECONOMICA svolte nell’ambito del Corso di Laurea in STATISTICA ED INFORMATICA PER LA GESTIONE E L’ANALISI DEI DATI (SIGAD) della Facoltà di Economia dell’Università degli Studi di Palermo. La ragione di questo progetto editoriale è nell’assenza di un testo dedicato da offrire agli studenti. Ciò, naturalmente, non esclude che il volume possa risultare utile anche in contesti didattici più generali quale supporto per un percorso applicato di alcuni classici temi eco- nomici ben aldilà dello specifico corso per il quale è stato progettato. Nell’offerta formativa dell’Ateneo di Palermo, il L…
Towards Experiencing Eating as a Form of Play
2018
There is an increasing trend in interaction design to engage with food. We note that most prior work targets instrumental benefits (for example see food tracking apps to manage nutritional intake). In contrast, in this article, we highlight the potential of technology to support eating as a form of play. We reflect on our own work to articulate two design strategies for game designers on how they can facilitate playful eating experiences using novel technologies. Ultimately, with our work, we aim to facilitate a more playful engagement around the way we eat.
An analysis of model predictive control with integral action applied to digital displacement cylinders
2020
This article aims to analyze Model Predictive Control (MPC) for the control of multi-chamber cylinders. MPC with and without integral action has been introduced. Three different algorithms have been used to solve the optimization problem in the MPC. The different algorithms have been compared with an industrial solver. The influence of changing mass, choosing a different middle line pressure, system delays, signal noise, velocity estimation, and changing pressure levels has been investigated. It is concluded that for the small prediction horizon used in the paper a simple algorithm such as A can produce results as good as the previously used Differential Evolution algorithm in less than hal…
Beyond Tandem Analysis: Joint Dimension Reduction and Clustering in R
2019
We present the R package clustrd which implements a class of methods that combine dimension reduction and clustering of continuous or categorical data. In particular, for continuous data, the package contains implementations of factorial K-means and reduced K-means; both methods combine principal component analysis with K-means clustering. For categorical data, the package provides MCA K-means, i-FCB and cluster correspondence analysis, which combine multiple correspondence analysis with K-means. Two examples on real data sets are provided to illustrate the usage of the main functions.
Extracting (good) discourse examples from an oral specialised corpus of wine tasting interactions
2015
International audience; This article outlines the semi-automated extraction of dictionary examples used in the compilation of a professional online dictionary of wine tasting. Named OenoLex Bourgogne, this dictionary was started to respond to the demand for a lexicographic information tool from the French wine industry of Burgundy, the Bureau Interprofessionnel des Vins de Bourgogne.
Immediate or delayed retrieval of the displaced third molar: A review
2019
Background The displacement of a third molar is a rare occurrence, but it could lead to serious and/or life threatening complication. Aim of this review is to understand the most correlated causes of displacement and the possible solutions proposed in literature to avoid and solve this complication for maxillary and mandibular third molars at the appropriate time. Material and methods A search for "third molar displacement" was performed by using Pubmed database. Articles referred to soft tissues displacement, from 1957 to 2018, were included in the review. The references lists of all eligible articles were examined and additional studies were added to the review only if indexed on Pubmed. …
Decentralized Deployment of Mobile Sensors for Optimal Connected Sensing Coverage
2008
In this paper, we address the optimal connected sensing coverage problem, i.e., how mobile sensors with limited sensing capabilities can cooperatively adjust their locations so as to maximize the extension of the covered area while avoiding any internal “holes”, areas that are not covered by any sensor. Our solution consists in a distributed motion algorithm that is based on an original extension of the Voronoi tessellation.
