Virtual Reality and Other Realities
2017
Abstract In this chapter, we describe virtual reality and other mixed reality technological tools, highlighting the role they can play in the Clinical and Health Psychology fields: as stimulating, safe and controlled therapeutic contexts for applying psychological treatments; as ecological settings for conducting psychological assessment; and as a realistic laboratory for psychopathology to test research questions that would be very difficult or impossible to address in a traditional laboratory setting. The existing meta-analyses and systematic reviews of their efficacy are presented. The majority of studies have used virtual realities (VRs) as exposure techniques. This is not surprising, c…
Relationship Between Patient-Reported Outcomes and Clinical Outcomes in Patients With Morquio A Syndrome
2019
Abstract This cross-sectional analysis assessed the correlation between patient-reported outcomes (PROs) and clinical outcomes in 24 German patients with Morquio A. Clinical outcomes included 6-minute walk test (6MWT), 3-minute stair climb (3MSC) test, and joint range of motion as measures for endurance/mobility, forced vital capacity (FVC) and maximum voluntary ventilation (MVV) as measures for respiratory function, and height as an important manifestation. The PROs included the EuroQoL (EQ) 5D-5L (EQ5D-5L), to measure health-related QoL (HRQoL), and patients’ rating of their ability to walk, climb, or breathe. In adults, endurance and pulmonary function measures and height showed strong a…
The Flow-Volume-Measurement in Computer-Supported Lung Function Analysis
1982
For some years computers have been applied more and more in pulmonary function laboratories. On the one hand the medico-technical industry could connect older diagnostic systems with new calculators, on the other hand completely computerised lung function desks have been developed.
Simulation of laser generated ultrasound with application to defect detection
2008
Laser generated ultrasound holds substantial promise for use as a tool for defect detection in remote inspection thanks to its ability to produce frequencies in the MHz range, enabling fine spatial resolution of defects. Despite the potential impact of laser generated ultrasound in many areas of science and industry, robust tools for studying the phenomenon are lacking and thus limit the design and optimization of non-destructive testing and evaluation techniques. The laser generated ultrasound propagation in complex structures is an intricate phenomenon and is extremely hard to analyze. Only simple geometries can be studied analytically. Numerical techniques found in the literature have pr…
Excitation of surface plasmon polaritons guided mode by Rhodamine B molecules doped in PMMA stripe
2010
In this letter we show the inclusion of Rhodamine B molecules (RhB) inside a dielectric-loaded surface plasmon waveguide enables for a precise determination of its optical characteristics. The principle relies on the coupling of the fluorescence emission of the dye to plasmonic waveguided modes allowed in of the structure. Using leakage radiation microscopy in real and reciprocal spaces, we measure the propagation constant of the mode and as well as their attenuation length.
Usability analysis and visualization of Web 2.0 applications
2008
Nowadays companies and home users use Web sites offering services ranging from Web sites up to complex Web applications. Often the ergonomics of these applications remains unconsidered and they turn out to be hard to use. In order to examine the usability from within the Web applications, information about the usage of the application is collected. The techniques that have been used in the past for Web 1.0 are no longer adequate. Ajax programs (Web 2.0) are more flexible and require other techniques. This paper shows techniques for collection, analysis, processing and visualization of data for Web 2.0 applications.
A tool to estimate usability of Web 2.0 applications
2009
Nowadays, companies and home users use websites offering services ranging from web sites up to complex web applications. The ergonomics of these applications often remain unconsidered and the applications turn out to be hard to use. In this paper, a tool is presented to facilitate the examination of usability. Web 2.0 applications in particular are supported, because they are more flexible and require other techniques than traditional web applications. The paper explains how to collect, analyze, process and visualize usability data for Web 2.0 applications.
Assessment and Intervention with Wii Fit in the Elderly
2015
Nowadays, the number of elderly people is constantly increasing, and the prospective is that this collective will continue to grow in the future. As aging is a process that implies many changes and consequences for the person, it is important to focus the research on the improvement of the quality of life of this increasing age group. Psychologists dedicate a great amount of time to design programs that improve the health of the elderly, and that includes gathering information and statistically analyze it to interpret and provide recommendations for an improved design. Expert systems are a good solution to reduce the amount of work that these professionals have to dedicate, automatizing tas…
On the mechanisms involved in the tensile strength of a dissimilar Ti6Al4V/316L laser welded assembly
2021
International audience; The aim of the present work is to analyze the thermomechanical behavior of dissimilar laser seams by means of FE modeling. The case of a Ti6Al4V/316L assembly with vanadium insert was considered. Effective mechanical properties of the main materials and cords were first estimated from NHT measurements. Modeling of the double pass laser welding process was performed first by considering shrinking of the two weld seams during manufacturing, to get the residual stress state in the welded assembly. Modeling of the tensile test was performed in a second step to study the assembly behavior during loading. In these modeling results, the mesh was the cross-section of the mic…
