TL;DR: For shape optimization of pressure driven capillary barriers between microchannels and reservoirs, a multilevel interior point method relying on a predictor-corrector strategy with an adaptive choice of the continuation steplength along the barrier path is presented.
Abstract: We will be concerned with the mathematical modeling, numerical simulation, and shape optimization of micro∞uidic biochips that are used for various biomedical applications. A particular feature is that the ∞uid ∞ow in the ∞uidic network on top of the biochips is induced by surface acoustic waves generated by interdigital transducers. We are thus faced with a multiphysics problem that will be modeled by coupling the equations of piezoelectricity with the compressible Navier-Stokes equations. Moreover, the ∞uid ∞ow exhibits a multiscale character that will be taken care of by a homogenization approach. We will discuss and analyze the mathematical models and deal with their numerical solution by space-time discretizations featuring appropriate flnite element approximations with respect to hierarchies of simplicial triangulations of the underlying computational domains. Simulation results will be given for the propagation of the surface acoustic waves on top of the piezoelectric substrate and for the induced ∞uid ∞ow in the microchannels of the ∞uidic network. The performance of the operational behavior of the biochips can be signiflcantly improved by shape optimization. In particular, for such purposes we present a multilevel interior point method relying on a predictor-corrector strategy with an adaptive choice of the continuation steplength along the barrier path. As a speciflc example, we will consider the shape optimization of pressure driven capillary barriers between microchannels and reservoirs.

TL;DR: Application of computer graphics and animated schematics, driven by the model, provides accurate display of the most intricate phenomena behind the PAT operation, facilitating the solution of various analysis, design, and control problems.
Abstract: A mathematical model of a pointing, acquisition, and tracking (PAT) system intended for laser-based intersatellite communication is developed and implemented in software in the form of a simulator. It represents major dynamic channels of the system and complex interaction of operational conditions, disturbances, and design parameters thus facilitating the solution of various analysis, design, and control problems. Application of computer graphics and animated schematics, driven by the model, provides accurate display of the most intricate phenomena behind the PAT operation. Coupled with a working laboratory prototype of the PAT system through a data communication board, the simulator is capable of displaying both simulated and real variables serving as a diagnostic tool. The simulator has been applied for development and verification of a novel jitter compensation scheme.
