Statistical modeling and analysis of audio-visual association in speech
… between associated and non-associated audio-visual observations. Various methods for modeling our audio-visual observations and ways of carrying out this test are studied and their relative performance is compared. We discuss issues that arise from the inherently high dimensional nature of …

Centrifuge modelling of the behaviour of geosynthetic-reinforced soils above voids
… stress levels. A plane-strain model allowed visual observations of the deformation mechanisms using Particle Image Velocimetry. Granular soils and model clay liners were tested, as would be relevant to embankments and landfills respectively. These soils were tested with and without the …

Survey of Flavonoids and Their Distribution in Different Kinds of Onions Using High Performance Liquid Chromatography and Gas Chromatography Mass Spectrometry.
… The chromatograms obtained were patterned using visual observations, scatter plot study, correlation co-efficient, and ANOVA to evaluate the significant difference of the distribution of flavonoids in varieties of onions. The organic white onions seem to have closer flavonoids profile to that of …

Characterization of a Low Current LaB6 Heaterless Hollow Cathode with Krypton Propellant
… ranging from 40 to 150 kHz. Lastly, post-test visual observations of the cathode components show signs of emitter poisoning and keeper erosion.

Zooplankton, Macroinvertebrate, Herpetile, and Ichthyofaunal Biodiversity of Riverine Habitat on the Upper Missouri River
… the molluskan fauna was sampled through visual observations with the use of a shell bar, and with the petit ponar dredge. Herpetiles were collected through visual observatiosn and with a combination drift fence and funnel trap. Finally, the ichtyofauna was sampled using both active, …

ΜΕΛΕΤΗ ΔΑΚΤΥΛΙΟΕΙΔΟΥΣ ΔΙΦΑΣΙΚΗΣ ΡΟΗΣ ΣΕ ΟΡΙΖΟΝΤΙΟ ΑΓΩΓΟ
… BY COMBINING SIGNAL CROSS-CORRELATION DATA WITH VISUAL OBSERVATIONS, IT IS SHOWN THAT THE DISTURBANCE WAVES TEND TO DEFORM RAPIDLY, MOVE ON A PLANE INCLINED WITH RESPECT TO THE VERTICAL, AND COVER AN INCREASINGLY LARGER PORTION OF THE CIRCUMFERENCE WITH INCREASING GAS VELOCITY. THE MEAN LARGE …

Comparison of Artificial Flavors in Commercial Products and Actual Natural Flavor via Gas Chromatography Mass Spectroscopy Data.
… obtained were patterned using simple visual observations, scatter plot designs, Mann-Whitney U Test, and correlation coefficients. The artificially flavored commercial products tend to have simpler chromatograms. The Burger King® milkshake, Gatorade®, and Hi-C® are the most similar to …

Studies on growth and filtration of the antagonistic biocontrol yeast Cryptococcus albidus
… capsule. Viscosity measurements and visual observations of precipitation of the polysaccharide with ethanol were evidence extracellular polysaccharide suspended in the surrounding media. In this study, alteration of the composition of the growth medium and various pre-filtration …

Success Classification for Object Navigation
… that learns and compares embeddings for visual observations and object categories and find that it works well at predicting success, outperforming both naive baselines and a heuristic-based classifier. We also find no improvement when using a ensemble model for semantic segmentation, …

Model-based Planning for Efficient Task Execution
… decide their next moves by reasoning about both visual observations and high-level language instructions. However, they plan in a high-dimensional latent space, opaque to human collaborators. Hence, it is difficult for humans to understand the agent’s decision-making process. This lack of …

Liquid extraction with single droplets-effect of chemical reaction
… by the Handlos and Baron model ... From visual observations of a stationary droplet in contact with the continuous phase during the transfer process, it was concluded that the deviation between the theoretical models and the experimental data was due to a special type of interfacial …

High-dose mode of mortality in Tribolium: A model system for study of radiation injury and repair in nonproliferative tissues
… the dose-independent pattern of mortality began. Visual observations of heavily-irradiated Tribolium suggested neural and/or neuromuscular damage, as had been previously proposed by others for lethally-irradiated wasps, flies, and mosquitoes. Results of experiments using fractionated high doses …

3D shape perception from vision and touch
… this direction has been primarily relying on visual observations. Vision, however useful, has inherent limitations due to occlusions and the 2D-3D ambiguities, especially for perception with a monocular camera. In contrast, touch gets precise local shape information, though its efficiency for …

Impact of human vocal fold vibratory asymmetries on acoustic characteristics of sustained vowel phonation
… therapeutic, and surgical decisions by coupling visual observations of vocal fold tissue motion with auditory-perceptual assessments of voice quality. The details of the relationship between vocal fold tissue motion and the voice produced are not fully understood, and there is recent evidence …

Utilization and Synthesis of Symbolic World Models for Safe, Generalizable, and Efficient Action
… explore learning a world model directly from observations and actions gathered from interacting with an environment. We combine symbolic and neural synthesis techniques to enable efficient world model synthesis even from visual observations. Together, these projects demonstrate the versatility …

Water Spreading Under Low Flow Conditions for Vegetated Treatment Area Applications
… effect of the spreaders on the flow of water and visual observations were made to determine what properties of the spreaders most affected the spreading efficiency of the spreader types.<br /> All of the spreader types tested showed an increase of water spreading efficiency when compared to a …

Estimating Floodplain Vegetative Roughness using Drone-Based Laser Scanning and Structure from Motion Photogrammetry
… values of field data (e.g., velocity probe and visual observations). We compared the model simulations to seven actual high-flow events during the fall of 2018 and 2019 using measured field data (velocity sensors, groundwater well height, marked flood extents). We used a t-test to find that all …

Burrowing Behavior of the Fiddler Crab <i>Uca panacea</i> in Relation to Food Availability
… crabs were observed for droving behavior through visual observations; evidence for this behavior was assessed further by determining sediment organic content. Although the organic content did increase significantly as distance increased from the edge of the water, fiddler crabs did not exhibit …
