Catching the 'Network Science' Bug: Insight and Opportunity for the Operations Researcher

Abstract: Recent efforts to develop a universal view of complex networks have created both excitement and confusion about the way in which knowledge of network structure can be used to understand, control, or design system behavior. This paper offers perspective on the emerging field of “network science” in three ways. First, it briefly summarizes the origins, methodological approaches, and most celebrated contributions within this increasingly popular field. Second, it contrasts the predominant perspective in the network science literature (that abstracts away domain-specific function and instead focuses on graph-theoretic measures of system structure and dynamics) with that of engineers and practitioners of decision science (who emphasize the importance of network performance, constraints, and trade-offs). Third, it proposes optimization-based reverse engineering to address some important open questions within network science from an operations research perspective. We advocate for increased, yet cautious, partic...

Navigating in natural environments: a virtual environment training transfer study

Abstract: The ability to use virtual environments as either an abstraction of a space, similar to a map, or as a simulation of the space itself has suggested to many that it would be a useful tool in terrain familiarization of unknown environments. Up to this point, all research in this area has focused on building interiors and urban environments which are significantly different from natural environments in terms of navigation cues and useful wayfinding techniques. The experiment we present uses a virtual environment, as compared to a map only or real-world conditions on navigation tasks in a natural environment. We show that navigation ability is more important to performance than the training method, with the virtual environment being most effective for intermediate orienteers as compared to advanced or beginner orienteers.

Perceptual ability with real-world nighttime scenes: image-intensified, infrared, and fused-color imagery.

Abstract: This study investigated human perceptual performance allowed by relatively impoverished information conveyed in nighttime natural scenes. Researchers used images of nighttime outdoor scenes rendered in image-intensified low-light visible (i-squared) sensors, thermal infrared (ir) sensors, and an i-squared/ir fusion technique with information added. They found that nighttime imagery provides adequate low-level image information for effective perceptual organization on a classification task, but that performance for exemplars within a given object category is dependent on the image type. Overall performance was best with the false-color fused images. This is consistent with the suggestion in the literature that color plays a predominate role in perceptual grouping and segmenting of objects in a scene and supports the suggestion that the addition of color in complex achromatic scenes aids the perceptual organization required for visual search. The study addresses the issue of assessment of perceptual performance with alternative night-vision sensors and fusion methods and begins to characterize perceptual organization abilities permitted by the information in relatively impoverished images of complex scenes. Applications of this research include improving night vision, medical, and other devices that use alternative sensors or degraded imagery.
