Over a decade of face-to-face GSS research and practical experience suggests that facilitation skills maybe just as important as the collaborative support tools a team uses. Facilitation research in face-to-face environments has proven to be complex and the results have been varied. While insights have been gained through both research and real work(More)
—Modeling propagation channels for future pico-cellular indoor THz communication systems requires the knowledge of the reflective properties of building materials. The reflectivity of smooth, optically thick materials can be modeled with Fresnel equations. In case of materials with a rough surface, diffuse scattering reduces the power reflected in the(More)
We have extensive experience with distributed facilitation of synchronous virtual meetings since 1992. More recently , we have gained experience in asynchronous virtual meetings and have learned lessons from which best practices have been distilled. Best practices for synchronous and asynchronous distributed facilitation give insight into requirements for(More)
—Dielectric reflectors have recently been proposed to be a key component for future wireless terahertz communication systems. Here, we investigate the dispersion properties of a mirror which consists of nine layers of two different dielectric materials. The layers differ considerably in their refractive index. The structure is highly reflecting and(More)
Group Support Systems (GSS) technology is still in the early stages of its diffusion process. There are several thousand GSS installations worldwide, and that number is growing, but GSS have not yet achieved a mass market. It may be that studying adoption and diffusion of GSS within a single organization could yield insights that would help speed the(More)
