Special Applied Mathematics Seminar
Abstract: The concept of Dynamic Data Driven Application Systems (DDDAS) entails a dynamic and symbiotic feed-back control system between executing applications and measurements. DDDAS creates the ability to incorporate dynamically additional data into an executing application (these data can be archival or collected on-line), and reversely, applications will be able to dynamically steer the measurement process. Such capabilities offer the promise of augmenting the analysis and prediction capabilities of application simulations and the effectiveness of measurement systems, with a potential major impact in many science and engineering application areas. Enabling DDDAS requires advances in the application modeling methods and interfaces, in algorithms tolerant to perturbations of dynamic data injection and steering, and in systems software to support the dynamic environments of concern here. Research and development of such technologies requires synergistic multidisciplinary collaboration in the applications, algorithms, software systems, and measurements systems areas, and involving researchers in basic sciences, engineering, and computer sciences. The talk will address specifics on such technology challenges, will provide examples from ongoing research projects, and will discuss the recently announced Program Solicitation on DDDAS.

Abstract: A number of groups have reported microfluidic experiments consistent with liquid slip on solid surfaces. We present physical models which do not require the breakdown of the no-slip boundary condition but lead to results consistent with slip. We then propose a new method for probing slip based on the diffusion of a colloidal particle near a slip surface.
