Brainstem processing of vestibular sensory exafference: implications for motion sickness etiology
(Springer, 2014-04-20)
The origin of the internal “sensory conflict” stimulus causing motion sickness has been debated for more than four decades. Recent studies show a subclass of neurons in the vestibular nuclei and deep cerebellar nuclei ...
Operator Performance in Long Duration Control Operations: Switching from Low to High Task Load
(HFES, 2012-10)
Long duration, low task load environments are typical for nuclear power plant control rooms, where operators, after hours of operating under a low task load situation, may have to shift to a high task load situation. The ...
Global vs. local decision support for multiple independent UAV schedule management
(International Journal of Applied Decision Science, 2010)
As unmanned aerial vehicles (UAVs) become increasingly autonomous, time-critical and complex single-operator systems will require advance prediction and mitigation of schedule conflicts. However, actions that
mitigate a ...
SPICES: spectro-polarimetric imaging and characterization of exoplanetary systems.
(Experimental Astronomy, 2012-10)
SPICES (Spectro-Polarimetric Imaging and Characterization of Exoplanetary Systems) is a five-year M-class mission proposed to ESA Cosmic Vision. Its purpose is to image and characterize long-period extrasolar planets and ...
Supporting Intelligent and Trustworthy Maritime Path Planning Decisions
(International Journal of Human Computer Studies, 2010)
The risk of maritime collisions and groundings has dramatically increased in the past five years despite technological advancements such as GPS-based navigation tools and electronic charts which may add to, instead of ...
Learning Sparse Gaussian Graphical Model with l0-regularization
(2014-08-22)
For the problem of learning sparse Gaussian graphical models, it is desirable to obtain both sparse structures as well as good parameter estimates. Classical techniques, such as optimizing the l1-regularized maximum ...
Shared Authority Concerns in Automated Driving Applications
(2014-05-13)
Given the move toward driverless cars, which includes the more short-term goal of driving assistance, what the appropriate shared authority and interaction paradigms should be between human drivers and the automation remains ...
Supervised vs. Unsupervised Learning for Operator State Modeling in Unmanned Vehicle Settings
(Journal of Aerospace Computing, Information, and Communication, 2011)
In this paper, we model operator states using hidden Markov models applied to human supervisory control behaviors. More specifically, we model the behavior of an operator of multiple heterogeneous unmanned vehicle systems. ...
Human-Automation Collaboration in Complex Multivariate Resource Allocation Decision Support Systems
(International Journal of Intelligent Decision Technologies, 2010)
In resource allocation problems for systems with moving planning horizons and significant uncertainty, typical of supervisory control environments, it is critical that some balance of human-automation collaboration be ...
Gradient Projection Anti-windup Scheme on Constrained Planar LTI Systems
(2010-03-15)
The gradient projection anti-windup (GPAW) scheme was recently proposed as an anti-windup method for nonlinear multi-input-multi-output systems/controllers, the solution of which was recognized as a largely open problem ...
