As the mission and performance demands for naval ships have increased, they have become more complex comprising an increasing number of heterogeneous interdependent subsystems. This increased complexity requires new methods for the design and operation of these naval systems. The Georgia Institute of Technology Aerospace Systems Design Laboratory (ASDL) is(More)
BACKGROUND To determine the clinical benefits of systemic targeted agents across multiple histologies after stereotactic radiosurgery (SRS) for brain metastases. METHODS Between 2000 and 2013, 737 patients underwent upfront SRS for brain metastases. Patients were stratified by whether or not they received targeted agents with SRS. 167 (23%) received(More)
OBJECTIVES This study aims primarily to determine whether whole body MRI (WB-MRI) and Sestamibi Technetium-99m-bone marrow (MIBI) scans in the same patients produce the same estimate of disease load and location, and secondly, to study possible association between the bone disease detected by these scans and the effect on disease outcome and survival.

We are interested in designing applications for autonomous mobile robots and robot swarms to accomplish tasks such as terrain analysis, search and rescue, and chemical plume source tracing. These tasks require robots to avoid obstacles and reach a goal. We use X80Pro mobile robots designed and developed by Dr.Robot Inc. for task applications. The vendor(More)
