Connected and Autonomous Vehicles cooperate with the pedestrian in industrial sites based on trajectory optimization and vehicle signalization system

2020

Connected and autonomous vehicles (CAV) is the development trend in the field of transportation systems. Recent studies show that the resources sharing between pedestrians and CAV is a big challenge. Considering traffic safety and efficiency at that sharing point not only requires a collision avoidance system but also more communicative behaviors of the CAV. More precisely, pedestrian needs to understand the intention of the incoming CAV whether it will cross first or not according to its speed profile. This paper uses the optimal trajectory control to provide CAV with a communicative behavior. A scenario where CAV and pedestrian cooperate together to cross a conflict zone is studied. A com…

Implementation of an Innovation in Education Project in the Degree of English Studies at the University of Valencia

2010

Begona.Clavel@uv.es The 21st century is and surely will be characterized by multiple and dramatic changes at all levels, but especially in the field of technology. This paper examines how some of these changes influence the way in which languages in general, and English in particular, are taught nowadays. We show how we have applied an Innovation in Education Project methodology in some modules in the degree in English Studies. Our most important instrument is our E-Learning platform (Aula Virtual) which offers us numerous ways in which to bridge the gap between our students and the team of teachers and permits our students to learn through a more interactive type of methodology.

An approach towards the visual culture of the Barroque festival : portraits of visual presences

2014

ABSTRACT: In this study I deal briefly with some issues related to the visual culture of the Baroque festival; and more specifically, with those related to the royal portraits that were on display during the festive activities. To this end I place special emphasis on developing the concepts of presence, body and virtuality –as applied to those works or visual objects– from an approach that offers a new theoretical framework, namely, that which involves «image studies» or «visual culture studies» (Bildwissenschaft, Bildanthropologie y visual studies). KEYWORDS: Baroque Festival, Royal Portraits, Presence, Body, Virtuality, Image Studies. RESUMEN: En el presente estudio abordaremos brevemente…

Tempo lembrado, lido e experienciado no texto virtual

2015

In this article I will scrutinize Screen (2002, by WARDRIP-FRUIN & al.), a literary work set and experienced in a CAVE Virtual Reality environment, especially from the perspective of its temporal aspects. There are obvious themes of remembering, forgetting and textually constructing the past in this work, but most notably, Screen emphasizes the temporality of the reading act itself. I will analyze this highly special work in relation to the remembered, read, and bodily experienced time, and thus, attempt to better understand both the notion of fictive time and the temporality of fiction. Neste artigo vou examinar Screen (2002, por Wardrip-Fruin & al.), uma obra literária experimenta…

Collaborative Virtual Reality for Laparoscopic Liver Surgery Training

2019

Virtual reality (VR) has been used in many medical training systems for surgical procedures. However, the current systems are limited due to inadequate interactions, restricted possibilities of patient data visualization, and collaboration. We propose a collaborative VR system for laparoscopic liver surgical planning and simulation. Medical image data is used for model visualization and manipulation. Additionally, laparoscopic surgical joysticks are used to provide an opportunity for a camera assistant to cooperate with an experienced surgeon in VR. Continuous clinical feedback led us to optimize the visualization, synchronization, and interactions of the system. Laparoscopic surgeons were …

A collaborative virtual reality environment for liver surgery planning

2021

Abstract Surgical planning software is a key component in the treatment of tumor diseases. However, desktop-based systems provide only limited visualization and interaction opportunities. Moreover, collaborative planning among members of a surgical team is only possible to a limited extent. In this work, a collaborative virtual reality (VR) environment to assist liver surgeons in tumor surgery planning is presented. Our aim is to improve virtual resection planning between surgeons in a remote or co-located environment. The system allows surgeons to define and adjust virtual resections on patient-specific organ 3D surfaces and 2D image slices. Changes on both modalities are synchronized, whi…

Collaborative VR for Liver Surgery Planning using Wearable Data Gloves: An Interactive Demonstration

2021

Preoperative planning for liver surgery is a critical procedure to assess a potential resection and it supports surgeons to define the affected vessels and resection volume. Traditional surgical planning systems are widely used to support the planning with the usage of desktop-based 3D and 2D visualizations. However, desktop-based systems offer limited interactions and visualizations compared to virtual reality (VR) [3]. A suitable technique to support collaboration among surgeons is required. Our previous works [1], [2] illustrate that using collaborative VR is essential to enhance communication, teamwork, and over-distance collaboration. In this work, we present a collaborative VR prototy…

Probabilistic analysis of non-local random media

2008

Computational stochastic methods have been devoted over the last years to analysis and quantification of the mechanical response of engineering systems involving random media. Specifically analysis of random, heterogeneous media is getting more and more important with the emergence of new complex materials requiring reliable methods to provide accurate probabilistic response. Advanced materials, often used at nano or meso-levels possess strong non-local characters showing that long-range forces between non-adjacent volume elements play an important role in mechanical response. Moreover long and short-range molecular interactions may have random nature due to unpredictable fabrication proces…

Group interaction styles in a virtual context: The effects on group outcomes

2010

The influence of communication and information technologies (TICs) on group functioning and group outcomes is an important topic. Interdependent group work implies the need to communicate in order to share information and knowledge related to the task. The importance of this group interaction in the group functioning and outcomes stands out. In this sense, a line of investigation has arisen to study the role of interaction styles in the relationship between communication technology and group outcomes, as some functional or dysfunctional outputs depend on group interaction styles. From this perspective, the objective of this study is twofold: (1) to analyze the group interaction styles in vi…
