One looks like little more than a stethoscope head attached to a wire; the other seems to be an oven mitt with three metal disks sewn on. Simple, yes, but these prototype medical devices — developed by young Caltech researchers working on a SURF project — could one day save lives.

Four undergrads have spent the summer developing and refining the prototypes as part of the cell-phone medicine project, headed by Julian Bunn of the Center for Advanced Computing Research (CACR) and Mani Chandy, Simon Ramo Professor and professor of computer science at Caltech. The lofty long-term goal of the project?  To make the “10-cent medical checkup” a reality.

We have developed a Matlab-based prototyping toolbox for uncertainty quantification. The underlying uncertainty quantification framework is based on the concentration-of-measure inequalities. We implemented two global optimization schemes, Simulated Annealing and Differential Evolution, for uncertainty quantification. The implementation exploits sources of parallelization at the optimization level and within uncertainty quantification. Our toolbox offers a user-friendly interface and a robust optimizer for uncertainty quantification on physical models.
