متن کاملVirtual Research Conferences: A Case Based Analysis
Research conferences provide an important platform for idea exchange and validation as well as for social networking and talent hunt. Online social networks and collaborative web tools can make conferences budget friendly for sponsors, flexible for attendees, and environment friendly for the society without loss of effectiveness. While many conferences have adopted such tools during pre and pos...
متن کاملArchitecture and Design for Virtual Conferences: A Case Study
This paper presents a case study of the design issues facing a large multi-format virtual conference. The conference took place twice in two different years, each time using an avatar-based 3D world with spatialized audio including keynote, poster and social sessions. Between year 1 and 2, major adjustments were made to the architecture and design of the space, leading to improvement in the nat...
متن کاملCircumstellar features in hot DA white dwarfs
We present a phenomenological study of highly ionised, non-photospheric absorption features in high spectral resolution vacuum ultraviolet spectra of 23 hot DA white dwarfs. Prior to this study, four of the survey objects (Feige 24, REJ 0457-281, G191B2B and REJ 1614-085) were known to possess these features. We find four new objects with multiple components in one or more of the principal reso...
متن کاملFUSE observations of hot white dwarfs
We have analyzed FUSE observations of six hot white dwarf stars: four DA white dwarfs with Teff >∼ 45 000 K, the DAO Feige 55 (Teff ≈ 55 000 K), and the DA CD−38◦ 10980 (Teff ≈ 24 000 K). Photospheric lines from Si IV, PV, and S VI can be observed in the majority of the five hotter objects. Feige 55 shows also several other heavier elements. The measured abundances agree only partly with the pr...
