National Science Board’s Science and Engineering Indicators 2010 >international collaborations steadily growing indicated by co-authorship of journal articles Open Doors Report on Intern. Educational Exchange >Study abroad is growing but only 4% for year abroad World Economic Forum rankings > US falling behind in global competitiveness NSF shows increased international commitment > through its PIRE, IRES, IREE and IGERT programs Adding Value through international and interdisciplinary graduate research
How to Educate the Global Engineerat URI? Through entrepreneurial dual degree programs on all degree levels • By way of an integrative curriculum at home and overseas which allows students at the Bachelor’s level to pursue dual degrees in engineering (B.S.) and German, French, Spanish (B.A.) or Minors in Chinese and Asian Studies (Undergraduate IEP). • On the Master’s and PhD level, they receive degrees from two institutions; (from TU-BS + from URI) > a multi -disciplinary, multinational model to internationalize EE. • IEP students combine study with work abroad, and international research with hands-on, practical experience.
First year at home institution (URI) Second year at host institution (TU Braunschweig) Thesis completed at host institution Mutually supervised and accepted Joint defense (real or video conference) Supported by German government grant Supported by NSF PIRE grant Supported by industry scholarships URI students in the pipeline: six complete Four in process Dual Degree Masters Program
Open to all College Of Engineering programs Supported/encouraged by the NSF grant Ph.D. / Dr.-Ing. Minimum one-year residency abroad Common thesis Two advisors, two committees, two defenses All requirements met for both schools URI students in the pipeline: One complete > NASA; one in process Dual Degree Doctoral Program(supported by NSF-PIRE)

MICROFLUIDIC-BASED OCEAN APPLICATION: THE ROLE OF FLUID PRESSURES IN THE TRIGGERING OF TSUNAMOGENIC LANDSLIDES Flow In Pressure Ports Pressure Ports Pore Space filled w/ water Flow Out Dynamic Pore Pressure in Porous Media Modeled in a Micro-channel network Cyclic Triaxial Tests on Idealized and Real Soils MICRO-SCALE TESTING Experiments using mini- and micro-channels will provide data and insight into pore pressure response due to dynamic loading. Dynamic pressure pulses will be generated using a “water hammer” effect and a pneumatic actuator. The properties of the channel will be modified such that the pore pressure response can be compared to pore pressure generation in soils. MICROFLUIDIC MODELING Two different CFD models are currently being used to model the physical microfluidic experiments. The first one, FLUENT, is a FEM that solves the 3-D Navier-Stokes (NS) equations. The second one is a model developed by Prof. Krafczyk’s team at TU-BS, which is based on the Lattice-Boltzmann equations, that also simulate the dynamic behavior of Newtonian fluids similar to the NS equations. MACRO-SCALE TESTING Cyclic triaxial tests of artificial soil made of uniform glass spheres, with local pore pressure measurements, will provide insight into the fundamental pore pressure generation in soils due to seismic loading. Using uniform spheres provides control of pore diameter, leading to a clearer understanding of pore pressure response for various particle sizes.Actual sediment will be used in a second phase.

Accurate – Qualitative / Quantitative Results A Light-emitting Diode (LED) can provide a very specific and small range of wavelengths to reach the sample without the need for filters A Charged-Coupled Device (CCD) allows for intensity detection extremely inexpensively, without any optics, or laboratory equipment. Designing micro-fluidic chips with reaction chambers at optimal size to be placed directly on top of the sensor, eliminates the need for any lenses. Qualitative Results can than be turned into quantitative results through simple analysis with programs such as Matlab.
