Etruscanning is a project founded by the European Commission and it focuses on the investigation of new digitization and presentation techniques, in order to re-create the original context of the Etruscan graves. Several digital techniques have been applied for the stages of digitization, virtual restoration and reconstruction and communication. The possibility of working on two different tombs...

This paper presents a strategy for real-time generation of formation trajectories using a leader–follower approach. A trajectory generator prescribes the motion of a group of virtual vehicles, using a Lyapunovbased nonlinear controller that stabilizes the position of the leader in the reference frame of the virtual vehicles at a predefined distance vector. This strategy differs from the standar...

One aspect of the Langlands program for linear groups is lifting of characters, which relates virtual representations on a group G with those on an endoscopic group for G. The goal of this paper is to extend this theory to nonlinear two-fold covers of real groups in the simply laced case. Suppose G̃ is a two-fold cover of a real reductive group G. The main result is that there is an operation, d...

This paper presents the findings of a study on the understanding and attitudes of pre-service teachers in the use of scenario-based multi-user virtual environments in science education. The participants in the study used Virtual Singapura, a virtual world, and completed an open-ended questionnaire. Data from the questionnaire indicated that gender and current computer game use were likely to af...

This paper presents the findings of a study on the understanding and attitudes of pre-service teachers in the use of scenario-based multi-user virtual environments in science education. The pre-service teachers involved in this study used a scenario-based multi-user virtual environment as part of a lecture on problem-based learning in science education and were then required to complete an open...

Increasing complexity of software applications forces researchers to look for automated ways of programming and adapting these systems. Self-adapting, self-organising software system is one of the possible ways to tackle and manage higher complexity. A set of small independent problem solvers, working together in a dynamic environment, solving multiple tasks, and dynamically adapting to changin...

background: with the recent spread of virtual learning programs in universities, especially in the field of medical sciences, libraries play a crucial role to support these programs. this study aimed at investigating the skills required by librarians to support virtual learning programs in isfahan university and isfahan university of medical sciences.   methods: this was an applied survey study...

there has been a recent development and explosion of interest among academicians across a wide range of disciplines in the use of virtual class room. utilization of the virtual class room as a laboratory experimentation for teaching and learning has increased significantly in recent years as development tools for web based applications have become easier to use and computers have become more ca...
