In information theory, it is of recent interest to study variability of the uncertainty measures. In this regard, the concept of varentropy has been introduced and studied by several authors in recent past. In this communication, we study the ...

The allure of the metaverse along with Virtual Reality (VR) technologies and speed at which they are deployed may shift focus away from security and privacy fundamentals. In this work we employ classic exploitation techniques against cutting edge ...

Training in virtual environments (VEs) has the potential to establish mental models and task mastery while providing a safe environment in which to practice. Performance feedback is known to contribute to this learning; however, the most effective ways ...

In this study, a new supervised noise-artifact-robust heart arrhythmia fusion classification solution, is introduced. Proposed method consists of structurally diverse classifiers with a new QRS complex geometrical feature extraction technique. Toward ...

Study on the enterprise’s technology innovation from the perspective of VE is to consider innovation as an activity or a process, and the purpose of analysis is to make a choice of the innovation strategy by functions and life-cycle cost analysis. ...

Human movement in virtual environments (VEs) is a largely unstudied area, and there are no well-established methods of measuring it in VEs. Consequently, it is unclear how movement affects the experiential side of VEs. We introduce a novel method of ...

The research area of spatiotemporal visualization has received much attention over the past decade considering that visualization is very much needed for dealing with large and complex spatiotemporal datasets. In this paper we present the visualization ...

Multi-user virtual environments implemented across the web allow many users to interact with the virtual world and each other in. The current standard for embedding virtual worlds in the Internet, VRML 2.0, provides links between these worlds, but it ...

This paper describes a case study and proposes two different services implemented in an Italian footwear district to support shoe producers in managing automatically their temporary partnerships with suppliers and customers through ICT applications. The ...

The pervasive use of communication and information technologies can be seen as a driving force to develop distributed organisations. As far as collaborative business is concerned, short-term e-collaboration can be developed. In this case, security ...

We present a first study of the effects of frame time variations, in both deviation around mean frame times and period of fluctuation, on task performance in a virtual environment (VE). Chosen are open and closed loop tasks that are typical for current ...
