Due to engineering limitations and cost constraints, the dynamics of the electronic industry are continually changing. Commercial companies increasingly recognize the need to differentiate their products through research in areas other than device scaling, such as new circuit architectures and computing algorithms.
The Lagrange program seeks to develop new mathematical approaches to optimization problems in uncertain, dynamic, multiscale, and high-dimensional settings. By bridging methodologies developed for both discrete and continuous optimizations, Lagrange aims to enable solutions for complex, realistic problems that involve dynamic environments, rapidly changing requirements, and increasing or decreasing amounts of information.
Synthetic chemistry is important across countless technological areas, from medicines to energetics to advanced coatings to functional materials. While our synthetic capabilities have developed rapidly over the last century, current approaches are still slow and inefficient, with poor reproducibility and scalability and limited use of prior knowledge. Such an approach not only limits production of known materials, but also impedes discovery of better synthetic routes and completely new molecules.
Military platforms—such as ships, aircraft and ground vehicles—rely on advanced materials to make them lighter, stronger and more resistant to stress, heat and other harsh environmental conditions. Currently, the process for developing new materials to field in platforms frequently takes more than a decade. This lengthy process often means that developers of new military platforms are forced to rely on decades-old, mature materials because potentially more advanced materials are still being developed and tested, and are considered too large a risk to be implemented into platform designs.
As a global force, the U.S. military is called upon to conduct missions that subject its platforms to extreme operational environments and structural loads. The endurance and performance of future Department of Defense platforms may call for the availability of materials with structural properties that significantly surpass current technology.
