Email: Complex systems, emergent computing and applications to engineering
Complexity is inherent to living systems. The meaning of living systems complexity is based on continuous evolution of structural organizations crossed by energetic fluxes. The whole comprehension of all the interactions of the living systems components inside their environment is needed to understand them. As a major complexity property, we can say that the reduction of the complete interaction network of the components of a living system does not allow to understand it, breaking with its complexity. The current natural and social World deals with this complexity property and need an accurate comprehension of this complexity, both for environmental purposes and for economical or geopolitic purposes. The Earth ecosystem equilibrium evolution is nowadays highlighted by local perturbations generated by human development and deep climatic perturbations could result of that. Geopolitic is also nowadays in fast and deep evolution as the result of the intensive development of modern communication processes which has transformed the old geographical cultural clustering. Interaction networks and patterns of emergent organizations are the keys of complex systems concepts understanding with which the current world must deal. Dissipative structures (following I. Prigogine) are the basis of the energetic approaches of self-organization criticality phenomena. We will present how computer science which can be considered as the science of modelling, dealing with information theory and systems conception can propose today, some models for self-organization processes. Cellular automata, sand pile models, segregation models (based on the works of the nobel price Thomas Schelling), agent-based modelling, social insects modelling for swarm intelligence can be the basis of relevent simulations for a better understanding of natural, economical or geopolitical systems that we have to face today.

Numerical Simulations of Transient Flows in Shock Tube and Validations with Experimental Measurements
This paper describes the numerical simulations of transient flows in shock tube which involves multiple reflections of shockwaves, contact surface and expansion waves and their interactions. The numerical formulations solve the fully compressible Reynolds Averaged Navier Stokes (RANS) equations set using finite volume method. The numerical results are validated against analytical solutions and experimental measurements in the high speed flow test facility available at the Universiti Tenaga Nasional (UNITEN), Malaysia. Experimental tests for different operating conditions have been performed. High precision pressure transducers were used to measure the pressure history at two different locations within the shock tube. Experimental results were compared with the numerical results and good agreements were obtained. The numerical simulations also revealed that the flow tend to be very unstable in the region close to the diaphragm after the reflected shock wave interacts with the contact surface.
