Entities interacting on the web establish their identity by creating virtual personas. These entities, or agents, can be human users or software-based. This research models identity using the Entity-Persona Model, a semantically annotated social network inferred from the persistent traces of interaction between personas on the web.

Proceedings of the ACM symposium on Virtual reality software and technology, 1998
There is no doubt that 3D interfaces edged 2D ones in 3D modeling applications. 2D input devices cannot provide 3D information directly and are less efficient. Direct manipulation, which is highly desirable in 3D modeling, is also impossible. This paper describes the design and implementation of a virtual hand interface for a 3D modeler, which can be ...

A model of virtual organisations
Journal of Information Science, 1998A model is presented of a virtual organisation that contains four variables: connectivity, purpose, technology and boundary. Four cases are analysed to illustrate the applicability and usefulness of the model. Based on the model, we make predictions for the stability of virtual organisations and creations of new forms of this organisational type.

Modelling of virtualized servers
2015 38th International Conference on Telecommunications and Signal Processing (TSP), 2015The virtualized systems are one of the key elements of the next generation IT infrastructures. Modeling it will prevent mistakes, and oversized management. Opennebula is one of the most current open source cloud management solutions. Together with Haizea, they are a powerful tool to model and manage a virtualized infrastructure trough the API of ...

Modeling the world: the virtualization pipeline
12th International Conference on Image Analysis and Processing, 2003.Proceedings., 2004High quality, virtual 3D models are quickly emerging as a new multimedia data type with applications in such diverse areas as e-commerce, online encyclopaedias, or virtual museums, to name just a few. The paper presents new algorithms and techniques for the acquisition and real-time interaction with complex textured 3D objects and shows how these ...

Formal Modeling of Virtual Machines
IEEE Transactions on Software Engineering, 1978A preliminary example of program development demonstrates that the control-independent implementation of data types can lead to very inefficient code. The concept of a data space, which emphasizes the interaction between data and control structures, is introduced as a formal model of virtual machines.

The Virtual Patient Specific-Model and the Virtual Dental Model
Seminars in Orthodontics, 2011The current trend in orthodontic records is toward an integrated virtual 3-dimensional (3D) model with soft tissue, hard tissue, and dentition. An important part of this complete 3D record is the dental model. Cone beam computed tomography allows the taking of all radiographic records and the creation of virtual dental models out of a single scan.

Data modeling for the virtual observatory
Astronomy and Computing, 2015Abstract The data modeling effort has played a key role in the Virtual Observatory project, and contributed to the effort to build a common reference framework to describe the necessary information attached to astronomical data: the metadata. Such metadata describe the observing parameters and characterize and qualify the observed measurements. These
