Statistical Modeling for the Flow of Short Fibers Composites

1994

Numerical results are given for the flow of fiber composites modelled as suspensions of non spherical particles. In this framework, because the many particles rotate, their state of orientation is described with a statistical approach. We used these methods to compute coupled solutions in which the orientation of the particles is affected by the flow and the flow itself depends on the orientation of the particles. The computation methods involve an augmented lagrangian approach and a streamline upwind petrov galerkin formulation to solve the convective orientation equation.

Interweaving visual and audio-haptic augmented reality for urban exploration

2018

While ordinary touchscreen-based interfaces on urban explorer applications draw much of a user's attention onto the screen, visual and audio-haptic augmented reality interfaces have emerged as the two main streams for enabling direct focus on the surroundings. However, neither interface alone satisfies users in the highly dynamic urban environment. This research investigates how the two complementary augmentation can coexist on one system and how people adapt to the situation by selecting the more suitable interface. A prototype was deployed in a field experiment in which participants explored points of interest in an urban environment with both interfaces. The engagement with the surroundi…

Phase behaviour of Ag2CrO4 under compression: Structural, vibrational, and optical properties

2013

We have performed an experimental study of the crystal structure, lattice dynamics, and optical properties of silver chromate (Ag2CrO4) at ambient temperature and high pressures. In particular, the crystal structure, Raman-active phonons, and electronic band gap have been accurately determined. When the initial orthorhombic Pnma Ag2CrO4 structure (phase I) is compressed up to 4.5 GPa, a previously undetected phase (phase II) has been observed with a 0.95% volume collapse. The structure of phase II can be indexed to a similar orthorhombic cell as phase I, and the transition can be considered to be an isostructural transition. This collapse is mainly due to the drastic contraction of the a ax…

Adolescents' postural control learning according to the frequency of knowledge of process

2019

Feedback is one of the most influential factors for motor skills learning. Physical Education teachers commonly use verbal cues to provide knowledge of process (KP) when teaching motor skills, but the ideal presentation frequency for KP in adolescents is unclear. The aim of this study was to compare the effectiveness of the frequency of KP (i.e., 100%, 67%, 0%) on dynamic balance. Thirty adolescents, age 14–15 years, participated in the study. Performance on a stabilometer platform was used to assess dynamic balance. Participants received feedback after each trial (100%), in two out of three trials (67%), or no feedback during 12 30-s trials of practice. Adolescents who received feedback (6…

Value co-creation process and measurement in 4.0 SMEs: An exploratory research in a B2B marketing innovation context

2021

The purpose of this exploratory research is to contribute to the lack of empirical research exploring techniques and protocols that can be used to measure the level of value obtained from using these technologies in the various marketing processes and in a business-to-business (B2B) context. By doing so, firms operating in fast changing dynamic environments can develop the right means to continuously adapt, integrate, reconfigure, and redeploy resources and capabilities to become more competitive and disruptive in their offerings. The phenomenon of interest is described by applying a case study qualitative approach to three 4.0 companies which use virtual reality (VR)/augmented reality (AR)…

Presence-inducing media for mental health applications

2015

Presence inducing media have recently emerged as a potentially effective way to provide general and specialty mental health services, and they appear poised to enter mainstream clinical delivery. However, to ensure appropriate development and use of these technologies, clinicians must have a clear understanding of the opportunities and challenges they will provide to professional practice.

Working Alliance Inventory applied to Virtual and Augmented Reality (WAI-VAR): Psychometrics and Therapeutic Outcomes

2015

This study examines the psychometric properties of the Working Alliance Inventory-Short (WAI-S) adaptation to Virtual Reality (VR) and Augmented Reality (AR) therapies (WAI-VAR). The relationship between the therapeutic alliance with VR and AR and clinically significant change (CSC) is also explored. Seventy-five patients took part in this study (74.7% women, Mage= 34.41). Fear of flying and adjustment disorder patients received VR therapy, and cockroach phobia patients received AR therapy. Psychometric properties, CSC, one-way ANOVA, Spearman’s Correlations and Multiple Regression were calculated. The WAI-VAR showed a unidimensional structure, high internal consistency and adequate converg…

Integrating Virtual Realities and Psychotherapy: SWOT Analysis on VR and MR Based Treatments of Anxiety and Stress-related Disorders

2021

© 2021 The Author(s). Published by Informa UK Limited, trading as Taylor & Francis Group.The use of virtual reality (VR) and mixed reality (MR) technology in clinical psychology is growing. Efficacious VR-based treatments for a variety of disorders have been developed. However, the field of technology-assisted psychotherapy is constantly changing with the advancement in technology. Factors such as interdisciplinary collaboration, consumer familiarity and adoption of VR products, and progress in clinical science all need to be taken into consideration when integrating virtual technologies into psychotherapies. We aim to present an overview of current expert opinions on the use of virtual…

Virtual and Augmented Reality Applied to the Perception of the Sound and Visual Garden

2022

The COVID-19 situation has encouraged the creation of ICT-based learning environments. Difficulties in performing activities in a garden setting can be overcome by using Virtual Reality (VR) and Augmented Reality (AR). The aim of this research is to evaluate the usefulness of VR and AR as an educational resource through contextualised sensory experiences in the garden. Eighty-seven trainee teachers took part, and a mixed methodology was used, for the analysis of the sound and visual elements of the garden and for reflection on the usefulness of VR and AR. An interpretive and inferential analysis of the AR-based compositions was carried out and of the drawings of the garden created by the pa…
