Plasma flows in the respective regions provide a framework for explaining the observed decreases with heliopause distance of the count rates of both solar system solar and anomalous cosmic rays diffusing outward from the heliopause and galactic cosmic rays diffusing inward. Formation of excited hydrogen atoms by chargeexchange collisions in interstellar plasma displaced and accelerated (as described in the discussion of solar system cosmic rays) by the motion of the heliosphere provides a mecha...

Comparing these observations with models provides key insights. We employ two three-dimensional (3D) time-dependent models that simulate the propagation of shocks, other specific features, and the background solar wind throughout the heliosphere, starting with the solar background and solar event boundary conditions near the Sun at 2.5 Rs. The Hybrid Heliospheric Modeling System with Pickup Protons (HHMS-PI) is a 3D timedependent Magnetohydrodynamic (MHD) simulation. HAFSS (HAF Solar Surface) is a 3D time-dependent kinematic simulation. Comparing our models with the observations indicates that solar effects are seen in the heliosphere, the HS, and the LISM in in-situ spacecraft measurements of plasma, magnetic field, energetic particles, cosmic rays, and plasma waves. There is quantitative agreement (at ACE, Ulysses, V1, V2) with data (e.g., solar wind, IMF, Ulysses SWICS pickup protons (PUPs)). Propagating shocks are slowed due to PUPs. The 3D locations of solar events and of various spacecraft are key to understanding the 3D propagation and timing of shocks, other specific features, and gradients throughout the heliosphere, HS, and LISM.

Investigating a Virtual Reality Based Subterranean Scenario Examining Augmented Reality Implications for Military Operators
Proceedings of the Human Factors and Ergonomics Society Annual Meeting, 2021

The military will soon offer operators the ability to wear augmented reality (AR) head-mounted displays (HMDs) while conducting missions. Therefore, it is crucial to understand how this emerging technology will positively and negatively impact Soldiers’ ability to execute missions. This paper describes the development of a virtual reality (VR) scenario designed to support user experience research for evaluating the efficacy of Soldier AR systems during sub-t operations. We describe usability test results that captured feedback and reactions to the VR scenario and the AR interface that presented critical information through a VR HMD. We conclude with lessons learned from our development process and future research plans.

Estimating the average speed to the shock as 750 km/s has produced consistently good associations between solar flares, or groups of them, and dynamic pressure increases at Voyager 2 and plasma wave events at Voyager 1. Furthermore, magnetograph observations confirm that polar coronal holes were present around the times of the flares to which the events at the Voyagers have been attributed. These calculations also provide revised estimates of the transport of heliospheric current sheet fluctuations. We discuss the possibilities that extrapolations from past observations and simulations based on them may provide insight into currently challenging issues and possible future developments.

With such abundance, consumers must use a variety of cognitive, emotional, and heuristic means to filter out and inhibit some of their responses. Here we use brand logos within a Go/No-Go task to probe inhibitory control during the presentation of familiar and unfamiliar logos. The results showed no differences in response times or in commission errors (CE) between familiar and unfamiliar logos. However, participants demonstrated a generally more cautious attitude of responding to the familiar brands: they were significantly slower and less accurate at responding to these brands in the Go trials. These findings suggest that inhibitory control can be exercised quite effectively for familiar brands, but that when such inhibition fails, the potent appetitive nature of brands is revealed.

Perceptual abnormalities have been reported in single cases or small series, but the causal link of such deficits to prosopagnosia is unclear. Our goal was to identify candidate perceptual processes that might contribute to prosopagnosia, by subjecting several prosopagnosic patients to a battery of functions that may be necessary for accurate facial perception. We tested seven prosopagnosic patients. Three had unilateral right occipitotemporal lesions, two had bilateral posterior occipitotemporal lesions, and one had right anterior-to-occipital temporal damage along with a small left temporal lesion. These lesions all included the fusiform face area, in contrast to one patient with bilateral anterior temporal lesions. Most patients had impaired performance on face-matching tests and difficulty with subcategory judgments for non-face objects. The most consistent deficits in patients with lesi...

Endowing Intelligent Transportation Systems (ITS) with such a capability could help solve crimes on roadways. One major impediment to the advancement of fine-grain vehicle recognition models is the lack of video testbench datasets with annotated ground truth data. Additionally, to the best of our knowledge, no metrics currently exist for evaluating the robustness and performance efficiency of a vehicle recognition model on live videos and even less so for vehicle search and localization models. In this paper, we address these challenges by proposing V-Localize, a novel artificial intelligence framework for vehicle search and continuous localization captured from live traffic videos based on input textual descriptions. An efficient hashgraph algorithm is introduced to compute valid target information from textual input. This ...

Simulations were run using the three dimensional (3D) time-dependent Hybrid Heliospheric Modeling System with Pickup Protons (HHMS-PI). HHMS-PI is an MHD solar wind model, expanded to include the basic physics of pickup protons from neutral hydrogen that drifts into the heliosphere from the local interstellar medium. We use the same model and input data developed by Detman et al. (2011) to now investigate the pickup protons. The simulated interval of 82 days in 2003-2004, includes both quiet solar wind (SW) and also the October-November 2003 solar events (the "Halloween 2003" solar storms). The HHMS-PI pickup proton simulations generally agree with the SWICS measurements and the HHMS-PI simulated solar wind generally agrees with SWOOPS (also on Ulysses) measurements. Many specific features in the observations are well represented by the model. We simulated twenty specific solar events associated with the Halloween 2003 storm. We give the specific values of the solar input parameters for the HHMS-PI simulations that provide the best combined agreement in the times of arrival of the solar-generated shocks at both ACE and Ulysses. We show graphical comparisons of simulated and observed parameters, and we give quantitative measures of the agreement of simulated with observed parameters. We suggest that some of the variations in the pickup proton density during the Halloween 2003 solar events may be attributed to depletion of the inflowing local interstellar medium (LISM) neutral hydrogen (H) caused by its increased conversion to pickup protons in the immediately preceding shock.

First, observers performed a tracking task at many viewing distances. Performance dropped to chance levels at small display sizes even though, in all conditions, observers could easily resolve the items and their motions. The limiting size for selection was roughly the same whether tracking one or three targets, suggesting that the resolution limit acts independently of the capacity limit of attention. Second, the closest spacing that still allowed individuation of single items in dense, static displays was examined. This critical spacing was about 50% coarser in the radial direction compared to the tangential direction, and was coarser in the upper as opposed to the lower visual field. The results suggest that no more than about 72 items can be arrayed in the central 30 degrees of the visual field while still allowing attentional access to each individu...

For these solar events we present our initial results at 1 AU from our HAFSS (Hakamada-Akasofu-Fry Source Surface) three-dimensional time-dependent kinematic modeling. Our simulations, using Wang-Sheeley-Arge maps and solar event observations, start at 2.5 R S from the center of the Sun. We use both the quiescent background solar conditions and the solar events (e.g., coronal mass ejections (CMEs)) as inputs and propagate outward. We compare HAFSS predictions with in situ spacecraft measurements and conclude that the July 2012 solar events caused a metaphorical "tsunami" in the plasma and magnetic field throughout the heliosphere/ heliosheath/interstellar medium. The simulations show evidence of shocks, interaction regions, and rarefaction regions in the inner heliosphere (1 AU) and shocks, global merged interaction regions (GMIRs) and rarefaction regions in the heliosheath. The shocks/interaction regions/GMIRs and the rarefaction regions are, respectively, analogous to the tsunami "crests" and "troughs". To provide important insights into 3-D processes, we simulated 1 AU observations (STEREO A and ACE) and observations at Voyager 2 (V2) and Voyager 1 (V1) far off the ecliptic plane: V2 at~30°S, 217°longitude, and 102 AU; V1 at 34°N, 174°longitude, and 124 AU. HAFSS successfully predicted observed CME arrival times at 1 AU. Our results for this tsunami are the first simulations for these events in the distant V2/V1 radial/latitudinal/longitudinal regions based on 3-D time-dependent modeling originating at the Sun. As solar activity slowly resumed this fleet of s/c observed relatively few and modest solar events, e.g.,
The Education of the Human Factors Engineer in the Age of Data Science

Do the lessons we learned and now teach regarding automation based on previous generations of technology still apply? What level of DS and ML expertise is needed for a human factors engineer to have a relevant role in the design of future automation? How do we integrate these topics into a field that often has not emphasized quantitative skills? This panel discussion brings together human factors engineers and educators at different stages of their careers to consider how curricula are being adapted to include data science and machine learning, and what the future of human factors education may look like in the coming years.

Effect of Aging on Visual Shape Distortion
Gerontology, 2004
Individuals experience a visual illusion created by shape interaction: when two shapes are presen... more Individuals experience a visual illusion created by shape interaction: when two shapes are presented successively and briefly, the form of the second (test) shape appears distorted due to the form of the first (prime) shape; this shape interaction is called the shape distortion effect. While age-related deterioration in performance is found in various aspects of visual perception, the effect of aging on the shape distortion effect has not been evaluated. The purpose of this study is to determine the effect of aging on the shape distortion effect. We measured the perception of briefly presented elementary shapes and of the shape distortion effect in 29 healthy volunteers, with ages ranging from 18 to 83 years. For each shape interaction trial, a prime rectangle was presented (vertical or horizontal) for 45 ms, followed by an interstimulus interval for 135 ms, a test circle for 60 ms and finally a random dot mask for 300 ms. The test circle was presented in each quadrant of the visual field. The prime rectangle was flashed either at the same position as the test circle (0 degrees offset, intrahemifield) or 11 degrees apart, displaced horizontally in the opposite hemifield (11 degrees offset, interhemifield). In the elementary-shape trials, there was no prime, and the test shape was a circle or an ellipse. Using the method of adjustment, the percent elongation [(longer diameter - shorter diameter)/(shorter diameter) x100] of the reproduced ellipse was computed. The mean percent elongation in response to the elementary shapes did not vary with increasing age. The shape distortion effect decreased significantly with increasing age during both intra- and interhemifield conditions. The mean shape distortion effect was larger for the intrahemifield condition than for the interhemifield one. The shape distortion effect decreases with advancing age while the perception of elementary shapes does not. These results indicate a severer age-related dysfunction of the cerebral processing of shape interaction than that of elementary-shape perception.
On the relationship between background EEG and the P300 event-related potential

The P3(00) event-related brain potential (ERP) was elicited with auditory stimuli when eyes were open/closed in the same subjects. Target stimulus probability was manipulated (0.20, 0.40, 0.60, 0.80) in different blocks under each eyes open/closed condition. Spectral analysis indicated that EEG power between 8 and 12 Hz demonstrated a similar scalp distribution as the P3 component of the ERP for the electrode sites employed. Spectral power and mean frequency were modestly correlated with P3 amplitude and peak latency primarily in the slower EEG bands, with associations observed across probability conditions and often strongest when target stimulus probability was .20. The results suggest that differences between individuals for EEG variation may contribute to P3 component variability, especially at the parietal recording site and under low target stimulus probability conditions when the P3 is largest and most stable.
