Abstract Introduction Virtual classroom training (VCT) is a novel educational method that permits accessible, distanced interactive expert instruction. We aimed to evaluate the efficacy of VCT in comparison face-to-face (FFT) and non-interactive computer-based learning (CBL) for basic surgical skills training. Method 72 participants recruited from five London medical schools underwent stratifie...

Virtual topology operations have been utilized to generate an analysis topology definition suitable for downstream mesh generation. Detailed descriptions are provided for virtual topology merge and split operations for all topological entities, where virtual decompositions are robustly linked to the underlying geometry. Current virtual topology technology is extended to allow the virtual partit...

There is abundant literature regarding virtual reality as a technology of interest in the present age. However, there are few comprehensive studies on strategies that can improve the level of urban design research using this technique. To investigate the issue, this paper first reviews the concept of virtual reality. Next, the opinions of experts in the field of virtual reality technology are s...

The theory of virtual knots is a generalization of the theory of classical knots proposed by Kauffman in 1996. In this paper solutions of certain problems of the theory of virtual knots are given. The first part of the paper is devoted to the representation of virtual knots as knots in 3-manifolds of the form Sg × I modulo stabilization. Using Haken’s theory of normal surfaces, a theorem is pro...

This paper presents the process of creation of virtual agents used in a virtual reality performance. The performance aimed to investigate how drama and performance could inform the creation of virtual agents and also how virtual reality could raise questions for drama and performance. The virtual agents were based on the performance of 2 actors. This paper describes the process of preparing the...
