Internalization of Non-Spherical Particles
This invention specifically relates to an interchangeable sleeve that encompasses a rotating, substantially cylindrical bioreactor. The sleeve supplies a time-varying electromagnetic force of from 0.05 to 0.5 gauss to the culture chamber of the bioreactor in order to increase cell growth and proliferation...
Briefs: Physical Sciences
Existing observing systems are inadequate to measure a variety of dynamic atmospheric processes. Ground-based or airborne systems do not observe over sufficiently large regions to capture the...

Atmospheric Turbulence Modeling for Aero Vehicles
Atmospheric turbulences are fractional order, and because of that, it is difficult to simulate these disturbances. Past models fall short in providing sufficiently accurate simulation of atmospheric turbulence, especially at high altitudes, for control designs of high-speed atmospheric vehicles. In...

Autonomic Quiescence
Biologically inspired autonomous and autonomic systems (AAS) are essentially about creating self-directed and self-managing systems based on metaphors such as that of the autonomic nervous system. Agent technologies have been identified as a key enabler for engineering autonomy and autonomicity in systems, both in terms of...

Change Detection in Orbital Images Using Relative Landmark Graphs
Traditional methods for change detection involve the pixel-wise registration of two images and a subsequent differencing operation that highlights any changes at the individual pixel level. These methods have two limitations: (1) they are computationally expensive, and (2) they are...

Heavy-Alkane Oxidation Kinetic-Mechanism Reduction
Oxidation chemical reactions of many practical fuels encompass thousands of species. When simulating complex turbulent reactive flows, it is impossible to account for the time and spatial evolution of all these species given current and foreseeable-future computer memory and time. This innovation...
