Introducing the European Space Agency Architectural Framework for Space-Based Systems of Systems Engineering

System of Systems (SoS) engineering introduces a higher level of complexity compared to conventional systems engineering, for the number and geographical distribution of resources, and for interoperability and agreements issues, for example. In domains such as defence or Information Technology, architecting methodologies have been introduced to address engineering needs deriving from this incre...

The Canadian Space Agency Space Learning Grants

forwarded to the International Astronautical Federation (IAF) – the organization responsible for the IAC for final selection. In 2011, close to 60 abstracts were submitted for consideration to be included at the congress in Cape Town, South Africa, with 21 Canadian students ultimately being selected for funding by the Canadian Space Agency to share their work with the conference delegation of i...

Summary Review of the European Space Agency’s Low Gravity Experiments

Oscillatory convection in binary mixtures: thermodiffusion, solutal buoyancy, and advection.

The role of thermodiffusive generation of concentration fluctuations via the Soret effect, their contribution to the buoyancy forces that drive convection, the advective mixing effect of the latter, and the diffusive homogenisation are compared and elucidated for oscillatory convection. Numerically obtained solutions of the field equations in the form of spatially extended relaxed traveling wav...
