Fuzzy-logic-based approach for identifying objects of interest in the PRIDE framework

2008

On-road autonomous vehicle navigation requires real-time motion planning in the presence of static and moving objects. Based on sensed data of the environment and the current traffic situation, an autonomous vehicle has to plan a path by predicting the future location of objects of interest. In this context, an object of interest is a moving or stationary object in the environment that has a reasonable probability of intersecting the path of the autonomous vehicle within a predetermined time frame. This paper investigates the identification of objects of interest within the PRIDE (PRediction In Dynamic Environments) framework. PRIDE is a multi-resolutional, hierarchical framework that predi…

Promoting multilingual communicative competence through multimodal academic learning situations

2016

This paper presents information on the factors affecting the development of multilingual and multicultural communicative competence in interactive multimodal learning environments in an academic context. The interdisciplinary course in multilingual interaction offered at the University of Jyväskylä aims to enhance students’ competence in multilingual and multicultural academic communication by promoting the use of their entire linguistic repertoire in various learning situations. Throughout the course, we observed the students’ engagement in multilingual and multicultural activities. These observations suggest that simultaneous use of multiple languages in synchronous and asynchronous learn…

Metalinguistic Development in First-Language Acquisition

1997

At a very early age, the child is able to manipulate language appropriately, both in its comprehension and its production. Later comes the ability to reflect upon and deliberately control its use. The emergence of these metalinguistic abilities must be distinguished from that of ordinary verbal communication. The key questions concerning this topic are: What is metalinguistics? What knowledge do metalinguistic abilities require? Are they conscious activities? And how do they develop? (also see the review by Tunmer in Volume 2 and by Nicholson in this volume.)

A VR-Enhanced Rollover Car Simulator and Edutainment Application for Increasing Seat Belt Use Awareness

2021

Most countries have active road safety policies that seek the objective of reducing deaths in traffic accidents. One of the main factors in this regard is the awareness of the safety measures, one of the most important being the correct usage of the seat belt, a device that is known to save thousands of lives every year. The presented work shows a VR-enhanced edutainment application designed to increase awareness on the use of seat belts. For this goal, a motorized rollover system was developed that, synchronized with a VR application (shown in a head-mounted display for each user inside a real car), rolls over this car with up to four passengers inside. This way, users feel the sensations …

Localization Based on Parallel Robots Kinematics as an Alternative to Trilateration

2022

In this article, a new scheme for range-based localization is proposed. The main goal is to estimate the position of a mobile point based on distance measurements from fixed devices, called anchors, and on inertial measurements. Due to the nonlinear nature of the problem, an analytic relation to compute the position starting from these measurements does not exist, and often trilateration methods are used, generally based on least-square algorithms. The proposed scheme is based on the modeling of the localization process as a parallel robot, thereby methodologies and control algorithms used in the robotic area can be exploited. In particular, a closed-loop control system is designed for trac…

PV-Alert: A fog-based architecture for safeguarding vulnerable road users

2017

International audience; High volumes of pedestrians, cyclists and other vulnerable road users (VRUs) have much higher casualty rates per mile; not surprising given their lack of protection from an accident. In order to alleviate the problem, sensing capabilities of smartphones can be used to detect, warn and safeguard these road users. In this research we propose an infrastructure-less fog-based architecture named PV-Alert (Pedestrian-Vehicle Alert) where fog nodes process delay sensitive data obtained from smartphones for alerting pedestrians and drivers before sending the data to the cloud for further analysis. Fog computing is considered in developing the architecture since it is an emer…

Context-Awareness in Ensemble Recommender System Framework

2021

Recommender systems that provide recommendations based uniquely on information over users and items may not be very accurate in some situations. Therefore, adding contextual information to recommendations may be a good choice resulting in a system with increased precision. In an early work, we proposed an Ensemble Variational Autoencoders (EnsVAE) framework for recommendation. EnsVAE is adjusted to output interest probabilities by learning the distribution of each item's ratings and attempts to provide diverse novel items that are pertinent to users. In this paper, we propose and investigate a context awareness framework based on the Ensemblist Variational Autoencoders model with integratin…

The Concept of Knowledge Society and Health Awareness at the University of Palermo

2022

In the last chapter of this volume, a series of activities and effects for the community will be illustrated in the Third University Mission (TM) context, namely those relating to knowledge society and health awareness. The TM of National Universi- ties includes traditionally the set of activities with which universities enter into direct interaction with society, providing a contribution that accompanies the two tradi- tional actions, such as research (in which mainly the interaction is with scientific communities) and teaching (in which an interaction takes place with the students). There are two possible forms of TM: 1) economic enhancement of knowledge (in order to encourage economic gr…

Propiedades psicométricas del Cuestionario de conciencia emocional en población infantil española

2016

La competencia emocional es la capacidad para percibir, expresar, comprender, regular y controlar nuestras emociones y las de los demás. La conciencia emocional es la competencia básica que permite el desarrollo del resto de competencias emocionales durante la infancia y la adolescencia. En este trabajo, se han estudiado las propiedades psicométricas de la versión española del Cuestionario de conciencia emocional, administrado a 1476 niños/as españoles (8-12 años). Se ha replicado la estructura original formada por seis factores. Se han estudiado la fiabilidad de los ítems y del instrumento, la validez de constructo, de contenido y concurrente, los resultados han sido satisfactorios. Se han…
