Ctr. Room 347Panel Organizers: Erik Blasch, Air Force Research Lab. (USA);Ivan Kadar, Interlink Systems Sciences, Inc. (USA)Panel Moderators: Ivan Kadar, Interlink Sciences Systems, Inc.(USA); Chee-Yee Chong, Independent Consultant (USA)Panel Members: Erik Blasch, Air Force Research Lab. (USA);Alex L. Chan, U.S. Army Research Lab. (USA); Chee-Yee Chong,Independent Consultant (USA); Laurie H. Fenstermacher,Air Force Research Lab. (USA); Ivan Kadar, Interlink SystemsSciences, Inc. (USA); Ronald P.

Steinberg, Independent Consultant (USA); Paul Tandy,Defense Threat Reduction Agency (USA); Shanchieh Jay Yang,Rochester Institute of Technology (USA)For a given application contextual information represents prior domainknowledge about the setting of the scenario/process to commence. Thecontextual knowledge can be acquired from prior (historical) experience,provided by external sources (e.g., user), learned from process experience,e.g., context awareness, prediction and search; and can be updated/corrected if changes are detected, e.g., by machine learning.Context is present in all aspects of processing and interpreting information,situation, data, text, imagery, target tracking/identification,web-analytics, and intelligence systems outputs, that is, in all aspects/levels of information fusion (IF). Context is a multi-faceted entity, andcan represent a setting for the assessment/interpretation of an event,scene, presence, situation, condition, constraint, influence, and manyother entities clearly scenario/application dependent. There is contextwithin context. Furthermore, context is not a static entity and can changeover time (e.g., operating conditions, environment, geography, weather,seasons, roads, traffic, attitudes, behavior, preferences) affecting theperformance of a given application if not managed and taken into account.Therefore, it is important to incorporate contextual information at theoutset in all IF levels and associated systems designs in order to enhancethe performance of the overall IF system and the on-going application.For example in tracking application one can describe at least fivecontextual categories: (1) domain knowledge from a user to aid theinformation fusion process through selection, cueing, and analysis, (2)environment-to-hardware processing for sensor management, (3) knowndistribution of entities for situation/threat assessment, (4) historicaltraffic behavior for situation awareness patterns of life (POL), and (5)road information for target tracking and identification. Appropriatecharacterization and representation of contextual information is neededfor future high-level information fusion systems design to take advantageof the large data content available for a priori knowledge target trackingalgorithm construction, implementation, and application.The objective of this panel is to bring to the attention of the fusioncommunity the importance of the application of contextual knowledgeto enhance IF, highlighting issues, illustrating potential approaches andaddressing challenges. A number of invited experts will discuss challengesof the fusion process and research to address these challenges. Thepanelists will illustrate parts of the above mentioned areas over differentapplications and address all levels of information fusion. Conceptual andreal-world related examples associated with the use of context to enhanceIF will be used by the panel to highlight impending issues and challenges.PANEL DISCUSSIONMetrology for Additive ManufacturingConf. 9489 · 2:10 to 3:30 pm · Location: Conv. Ctr. Room 331Moderator: Edward W. (Ted) Reutzel, Applied Research Lab.(USA)Panelists: Doug Rhoda, Wolf Robotics (USA), RadovanKovacevic, Southern Methodist Univ. (USA), Shawn Kelly,Edison Welding Institute (USA), Jyoti Mazumder, Univ. ofMichigan (USA), Edward Herderick, GE Corporate (USA)Process sensing plays an increasingly important role in a wide range ofmanufacturing processes, both to enable rapid assessment of quality andto provide critical data to real time control systems. Advanced sensors andexploding computational capability afford (i) practitioners, (ii) equipmentsuppliers, and (iii) researchers unprecedented opportunities to collect andanalyze complex sensor data to ensure quality product.This panel discussion brings together leaders representing these threecommunities to discuss sensing and control for laser, electron beam,and arc-based welding, metal deposition, and additive manufacturingprocesses. The current state of the art, current research, issues, andopportunities will be explored.8 SPIE DSS 2015 · www.spie.org/dss
