Seminar Series: Interface Design for Human-Centered Systems

Speaker: Anil Raj, M.D.
Research Scientist
Affiliation: Florida Institute for Human and Machine Cognition
Date: Friday, April 18, 2014
Time: 1:30 p.m. to 2:20 p.m.
Location: HPA1, Room 116
Contact: Dr. Tian Tian
Many human-machine tasks could benefit from bidirectional interaction between the system and the operator. The application space drives the process of solution design. For a given environment, the process may include cognitive task analysis, concept mapping and system modeling to identify interaction bottlenecks between the human machine team before ever attempting to implement a solution. This provides an opportunity to investigate the solution space before committing to assets to hardware. This guides the creation of a physical embodiment to address the systemic bottlenecks. The final step requires validation of the solution through demonstration of changes in cognitive effort. We will discuss this multistep process in the context of recent project.
Research Scientist Anil Raj, M.D. (University of Michigan School of Medicine, 1990), followed his general surgery internship as a contract general medical officer with the US Army for one year. His interests in aerospace medicine research led him to the Naval Aerospace Medical Research Laboratory in Pensacola, Florida, following a two-year fellowship as a National Research Council Resident Research Associate at the NASA Johnson Space Center, in Houston, Texas. Dr. Raj’s interests focus around the human physiologic and psychological responses to external forces, particularly how they affect situation awareness. He has been involved with the development, testing, and evaluation phases of the US Navy and NASA’s Tactile Situation Awareness System (TSAS), and directed the first helicopter and first Unmanned Aerial Vehicle flight tests of TSAS. Since joining the Florida Institute for Human and Machine Cognition in 1996, Dr. Raj has been involved with the development of human-centered interfaces and the development of automated systems for tracking, analyzing, and manipulating human response characteristics in dynamic task environments. He led development of methods for integrating heterogeneous software agents with human-centered interfaces and adjustable autonomy as part of the DARPA Improving Warfighter on machine learning systems for modeling brain function when using multi-sensory interfaces, investigating novel approaches for augmenting situation awareness for able-bodied and disabled individuals.

Seminar Series: Particle Transport, Deposition and Removal: Environmental and Biological Applications

Speaker: Goodarz Ahmadi
Dean of Engineering
Professor, Mechanical and Aeronautical Engineering
Affiliation: Coulter School of Engineering at Clarkson University
Date: Friday, March 21, 2014
Time: 1:30 p.m. to 2:20 p.m.
Web: Goodarz Ahmadi at Clarkson University
Applications of particle transport, deposition and removal in environmental and bio-logical flows are presented. The mechanics of particulate pollutant transport and deposition in turbulent flows are discussed. The numerical simulation airflow through the Reynolds averaged Navier-Stokes (RANS) equation, as well as DNS and LES is described. The stochastic models for simulation of instantaneous flow are also discussed. The Lagrangian particle trajectory anal-ysis method is presented, and the effects of various forces including drag, lift, gravity and Brownian are discussed. The nature of particle adhesion and removal from surfaces are also described, and re-entrainment of particles in turbulent flows is discussed. It is shown that the particle deposition and removal processes in turbulent flows are strongly affected by the near wall flow structures. Wind tunnel studies of particle transport, deposition and resuspension are also discussed. Examples of computational modeling of gas-solid flows in ducts, as well as, in indoor and outdoor air are described. The simulation procedure for particulate pollutant transport through human upper airways is discussed and sample results are presented. It is shown that computational modeling provided an efficient tool for studying gas solid flows in complex passages.
Goodarz Ahmadi is a Clarkson Distinguished Professor, and Robert R. Hill Professor of Mechanical and Aeronautical Engineering at Clarkson University. He has been serving as the Dean of Engineering of the Coulter School of Engineering at Clarkson in the last seven years.
His research interests include multiphase flows, particle transport and deposition, turbulence, granular flows, air pollution, and flow through porous and fractured media. His research has been supported by the National Science Foundation, the Environmental Protection Agency, Department of Energy, NASA, Corning, IBM, Xerox, Dura Pharmaceutical, NYSTAR and AFOSR.
He has authored three books and over 530 publications in archival journals. He also has made more than 1000 presentations at national and international technical conferences and has given more that 150 invited talks and short courses at other institutions. He is serving as a member of editorial board and/or editorial advisor board of eleven international journals.
He is a Fellow of ASME, ISME and ISCE and he an honorary member of Academy of Science of Iran.

Seminar Series: Overview of Design and Validation of the Fine Guidance Sensor Mechanisms for the James Webb Space Telescope

Speaker: Johanne Heald, Ph.D.
Affiliation: Canadian Space Agency
Montreal, Canada
Date: Friday, February 14, 2014
Time: 1:30 p.m. to 2:20 p.m.
Location: HPA1, Room 116
Three mechanisms have been developed for cryogenic operation in the Fine Guidance Sensor instrument to fly on the James Webb Space Telescope: Two translating mechanisms facilitate focusing of the Guider and Tuneable Filter imag-ing systems; and The Dual Wheel mechanism provides a selection of infra-red fil-ters and coronoagraphic masks for the Near Infrared Imager and Slitless Spectro-graph. A brief overview of each mechanism design is provided, along with the lat-est status with respect to qualification, life-testing, and flight until performance.
Dr. Johanne Heald is currently a structures engineer at the Canadian Space Agency in Montreal, Canada. She obtained her Bachelor’s degree in Engineering Science from the University of Toronto, and her Master’s degree from the Univer-sity of Toronto’s Institute for Aerospace Studies, where she studied the station-keeping of small craft in Low Earth Orbit. In 1996, she was a student at the Inter-national Space University summer program in Vienna, Austria. Subsequently, Jo-hanne worked at the European Space Agency as a navigation and guidance engi-neer, where she examined problems related to formation flying and errors in space-craft trajectories. She was a teaching assistant in Space Engineering at the ISU Summer Session in Cleveland in 1998, before going on to the University of Colo-rado at Boulder to begin her Ph.D. in Aerospace Engineering Sciences. Her doc-toral work examined the repeatability of precision deployable structures that are used for space telescopes. She also obtained a certificate in remote sensing from the University of Colorado in 2000. Johanne was a member of the organizing committee of the Space Generation Forum at the United Nations’ UNISPACE III conference, and has served as a member of the Board of Directors of the Canadian Alumni for International Space University (CAISU). Her current projects at the Canadian Space Agency involve the deployment and control of membrane struc-tures in space, the examination of space solar power, vibration testing of the instru-ment Canada is building for the Japanese Astro-H mission, and the development of structures for the Fine Guidance Sensor on the upcoming James Webb Space Tele-scope.
