We report on a procedure to focalize few-cycle laser pulses in dispersive media with controlled waveform. Stationarity of the carrier-envelope phase for extended depth of focus is attained by shaping the spatial dispersion of the ultrashort beam. An adjustable group velocity is locally tuned in order to match a prescribed phase velocity at focus. A hybrid diffractive-refractive lens system is p...

We are developing mmGrid (Multimedia Grid) as an extensible middleware architecture supporting multimedia applications in a grid computing environment. Our vision is to provide support for interactive applications from the following domains: graphics, visualization, streaming media and tele-immersion. The initial deployment will be within an enterprise as a mechanism for provisioning computing ...

In this paper, we demonstrate an immersive and interactive broadcasting production system with a new haptically enhanced multimedia broadcasting chain. The system adapts Augmented Reality (AR) techniques, which merges captured videos and virtual 3D media seamlessly through multimedia streaming technology, and haptic interaction technology in near real-time. In this system, viewers at the haptic...

Abstract The potential for crevice corrosion of UNS30400 stainless steel in the presence sulfate-reducing bacteria (SRB) was studied different media. Immersion studies found to occur test media supplemented with high chloride levels and SRB present gaps ~3 μm. Electrochemical measurements showed susceptibility this particular medium, demonstrated by a negative shift open circuit potential, incr...

Three Mg alloys, Mg-1.34% Ca-3% Zn (MCZ), Mg-1.34% Ca-3% Zn-0.2% Sr (MCZS), and Mg-2% Sr (MS), were examined to understand their bio-corrosion behavior. Electrochemical impedance spectroscopy and polarization scans were performed after 6 days of immersion in cell culture medium, and ion release and changes in media pH were tracked over a 28 day time period. Scanning electron microscopy (SEM) of...

Developing and implementing mission statements continues to be a widely used managerial strategy. This study tests a model incorporating the immersion and transportation dimensions of presence and media richness for evaluating the effectiveness of two commonly used strategies (paper versus video) for introducing a mission statement to members of an organization. Outcomes include participants‘ r...

This workshop will focus on the human experience when interacting with different media, such as virtual reality, computer games, simulation rides, television shows, radio programmes, or books. On the one hand, many of these media attempt to represent reality as convincingly as possible, whereas on the other hand many people seek out these media to escape reality, to become immersed in a differe...

In this paper, a new synesthetic documentation method that contributes to media art conservation is presented. This new method is called “e-Installation” in analogy to the idea of the “e-Book” as the electronic version of a real book. An e-Installation is a virtualized media artwork that reproduces all synesthesia, interaction, and meaning levels of the artwork. Advanced 3D modeling and telepre...

Virtual reality (VR) has had the reputation of being a revolutionising technology ever since it emerged in early 1960s, but virtual is not yet successful journalistic practice. Examining VR’s current situation and factors preventing from reaching its predicted potential digital journalism, this paper analyses user comments (n = 770) on 15 VR apps offered by media organizations, with help qualit...

Previous results indicate that arterial pulse pressure modulates release of arginine vasopressin (AVP) in humans. The hypothesis was therefore tested that an increase in arterial pulse pressure is the stimulus for suppression of AVP release during central blood volume expansion by water immersion. A two-step immersion model (n = 8) to the xiphoid process and neck, respectively, was used to atta...
