Draft Technical Program

Abstract:
Simulation-based decision support is an important tool in business, science,
engineering, and many other areas. Although traditional simulation analysis
can be used to generate and test possible plans, it suffers from a long
cycle-time for model update, analysis and verification. It is thus very
difficult to carry out prompt "what-if" analysis to respond to abrupt changes
in the physical systems being modeled. Symbiotic simulation has been proposed
as a way of solving this problem by having the simulation system and the
physical system interact in a mutually beneficial manner. The simulation system
benefits from real-time input data which is used to adapt the model and the
physical system benefits from the optimized performance that is obtained from
the analysis of simulation results.

This talk will present a classification of symbiotic simulation systems with
examples of applications from the literature. An analysis of these applications
reveals some common aspects and issues that are important for symbiotic
simulation systems. From this analysis, it is possible to identify a few basic
functionalities that can be provided by corresponding agents in our framework.
These can then be composed together by a specific workflow to form a particular
symbiotic simulation system. Finally, the talk will discuss the use of symbiotic
simulation as a decision support tool in understanding and steering complex
adaptive systems. Some examples of current applications being developed at
Nanyang Technological University will be described.

Abstract:
Visual reconstruction of dynamic events as 3D video, such as an actor
performance or sports action, has advanced to the stage where it is
possible to achieve free-viewpoint replay with a quality approaching
the captured video. In this talk, we present research going beyond
replay to allow the creation of 4D models which support interactive
animation control from captured performance whilst maintaining the
realism of video. 4D models are constructed by alignment of reconstructed
mesh sequences into a temporally coherent structure. Recent work has
introduced a non-sequential approach to non-rigid mesh mesh sequence
alignment which constructs a shape similarity tree to align across a
database of multiple sequences. This avoids problems of drift and
tracking failure associated with sequential alignment approaches.
Temporally aligned 4D models provide the basis for parameterisation of
multiple related sequences to give continuous interactive movement
control. Representation of multiple sequences in a 4D parametric motion
graph enables transition between multiple motions to achieve interactive
character animation.

Abstract:
Coalition Armed Forces have used simulations to enable training for some time and
in recent years training through distributed simulations have been proven as a means
to conducting training. This presentation introduces a number of challenges in
integrating Live, Virtual Constructive Simulations for Training and introducing
the Command and Control (C2) systems to provide mission planning and rehearsal
capability as well as augmenting support to operations with real feeds from the
wider battle-space network and operating picture.

The presentation will provide examples of current approaches, future architectures
and technology trends that may hold an answer to the challenges of distributed
training in defence.
