This paper reviews the basic ideas underlying one-dimensional uid dynamic models of coronal loops and presents some of their most recent applications. These models are an important theoretical support to explore the new scenario provided by the data of Yohkoh, SOHO and TRACE, and are useful to interpret observations, when supplemented by appropriate spectral synthesis codes. Possible developmen...

Cue exposure therapy has been reported to be an effective intervention for reducing binge eating behavior in patients with eating disorders and obesity. However, in vivo food exposure conducted in the therapist's office presents logistical problems and lacks ecological validity. This study proposes the use of virtual reality technology as an alternative to in vivo exposure, and assesses the abi...

We discuss string scale unification facilitated by exotic matter with masses at intermediate scales, between the observable sector supersymmetry breaking scale and the string scale. We point out a mechanism by which string scale unification may occur while producing a (lower) virtual unification scale independent of the location of the intermediate scale and the value of the string coupling. Th...

This chapter analyzes course delivery systems in the context of distance learning using the World Wide Web (WWW) and Internet in general. Many projects are focused on web based education (WBE) systems and tools, covering the spectrum of teacher, student and institutional needs for virtual education. These needs are addressed in traditional, face to face residential, education (we will call this...

Among designers of knowledge work environments (KWEs) it is common to distinguish between those involved in designing the virtual part (software designers) and the physical part (office tool manufacturers, architects etc.) of the environments. Recent advances in user interface technology, for example (Fitzmaurice et al. 1995, Harrison et al. 1998, Ishii and Ullmer 1997, Mackay 1998, Rekimoto 19...

This paper presents a Knowledge Management (KM) software tool which has been designed to support managing implementation of best practices and improvement initiatives within a VDO (Virtual Development Office) Network. A VDO Network is an organization integrated by SMEs, with a particular form of governance. Furthermore, the KM tool enables building a knowledge base of key capabilities available...

In this paper we analyse the ergonomic problems of many conventional Virtual Reality Systems. End-user tests have shown that many VR-Systems indicate weak points regarding the posture and projection properties. We describe the features and technical specifications of the newly developed system. For the development we have taken the directives and guidelines from the area of office work with vis...
