Development of a working simulator requires the flexibility to integrate various software models, to support interoperability, and facilitate performance optimizations. An object oriented framework is devised to support multithreaded integration of simulation, deformation, and interaction. A demonstration application has been implemented in Java, leveraging the features that are built into the language including multithreading, synchronization, and serialization. Future work includes expanding the capabilities of the framework with a broader range of model and interactive capabilities.

The simulator includes two PCs, a haptic device, and mirrored display. Debridement is performed on a virtual leg model with a shallow laceration wound superimposed. Trainees are instructed to remove debris with forceps, scrub with a brush, and rinse with saline solution to maintain sterility. Research and development issues currently under investigation include tissue deformation models using mass-spring system and finite element methods; tissue cutting using a high-resolution volumetric mesh and dynamic topology; and accurate collision detection, cutting, and soft-body haptic rendering for two devices within the same haptic space.

To unify and ease the usability and operation of the Grid, an integrated workbench tool 'g-Eclipse' is being developed to support Grid users, operators, and developers. g-Eclipse is built on top of the Open Source Eclipse framework, which provides a reliable eco-system backed by the Eclipse community and its vision is to provide a middleware independent framework for easy access to existing Grid infrastructures. As opposed to many thin client Grid portal solutions available - where, in the final step, the user can retrieve the output - g-Eclipse offers direct visualization capabilities of the data computed on the Grid. The aim of the g-Eclipse visualization component is to combine the tasks of ...

However, ontology repositories and their accompanying reasoning and rule languages face the disadvantage of bad runtime behavior, especially if the models grow large in size. We propose an architecture that uses tools and methods from the domain of Big Data processing in conjunction with an ontology repository and a rule engine to overcome potential performance bottlenecks that will occur in this scenario.
