TOWARDS THE OPTIMAL PIXEL SIZE OF DEM FOR AUTOMATIC MAPPING OF LANDSLIDE AREAS
Landslide landslide mapping DEM resolution Neural Net classification Maximum Likelihood classification
2017/7/12
Determining appropriate spatial resolution of digital elevation model (DEM) is a key step for effective landslide analysis based on remote sensing data. Several studies demonstrated that choosing the ...
Challenges in accurately modeling the complexity of human ingestive behavior: the influence of portion size and energy density of food on fMRI food-cue reactivity
accurately modeling ingestive behavior energy density of food
2018/11/12
Ingestive behavior is determined by a complex interaction between neurophysiologic and behavioral and environmental contributors that begins early in life. A better understanding of this complex regul...
Food portion size and energy density evoke different patterns of brain activation in children
energy density neuroimaging obesity pediatric portion size
2018/11/12
Background: Large portions of food promote intake, but the mechanisms that drive this effect are unclear. Previous neuroimaging studies have identified the brain-reward and decision-making systems tha...
A vegetable, fruit, and white rice dietary pattern during pregnancy is associated with a lower risk of preterm birth and larger birth size in a multiethnic Asian cohort: the Growing Up in Singapore Towards healthy Outcomes (GUSTO) cohort study
birth weight dietary patterns large for gestational age maternal diet preterm birth
2018/12/18
Background: Maternal dietary patterns during pregnancy have been shown to influence infant birth outcomes. However, to our knowledge, only a few studies have examined the associations in Asian populat...
Symposium MB5—Size Effects and Small-Scale Mechanical Behavior of Materials
nanocomposites nanocrystalline materials
2016/7/18
Deformation and failure mechanisms in materials become size-dependent when sample dimensions and/or microstructures approach the sub-micrometer regime. Size effects include the increase in strength of...
Sizing the Horizon: The Effects of Chart Size and Layering on the Graphical Perception of Time Series Visualizations
Visualization graphical perception time series line charts, horizon graphs
2016/5/24
We investigate techniques for visualizing time series data
and evaluate their effect in value comparison tasks. We
compare line charts with horizon graphs—a space-efficient
time series visualizatio...
