At LLNL Engineering, we seek to develop, promote, and exploit technologies essential to the analysis, design, monitoring, and control of large-scale, complex systems. Research in this area, termed “sensors to knowledge,” embodies development and deployment of sensors and the integration (or fusing) of their resulting data streams. The goal is to generate new understanding or knowledge of situations, thereby allowing anticipation or prediction of possible outcomes. With this knowledge, a more comprehensive solution may be possible for problems as complex as the prediction of disease outbreaks or an advance warning of terrorist threats. This very broad technical area includes development of integrated sensing, communication, and signal processing systems for efficient gathering of the data essential for real-time system monitoring. Our efforts also promote the development of new methodologies for combining measured data with computer simulations in order to achieve enhanced characterization and control of complex systems. |

Addressing these challenges falls naturally into three phases. First, information is gathered by sensing, monitoring, or otherwise measuring the system. In addition, existing data from databases, libraries, pictures, images, or prints may be used. Second, this information is then brought together in a coherent fashion to the analyst. This requires merging differing media and data to a useful format, usually in a visual display. The third and most difficult phase is the analysis and extraction of meaningful information from this information so that present and future behavior can be predicted. This last phase often includes sophisticated modeling and simulation of the processes, as well as developing algorithms to extract information from images and other types of data.
