Modeling Physical-Biological Responses to Climate Change in the California Current System
Climate Changel California Current System
2015/7/16
Understanding the effects of climate change on planktonic ecosystems requires the synthesis of large, diverse data sets of variables that often interact in nonlinear ways. One fruitful approach to thi...
Algorithmic shape modeling with subdivision surfaces
Procedural models Multi-scale surfaces Catmull–Clark subdivision Shape blending Warping and morphing Fractals Signal mesh processing
2015/7/15
We present methods for synthesizing 3D shape features on subdivision surfaces using multi-scale procedural techniques. Multi-scale synthesis is a powerful approach for creating surfaces with different...
Global Modeling of Internal Tides Within an Eddying Ocean General Circulation Model
Internal Tides Within Ocean
2015/7/14
Ocean tides, and the atmospherically forced oceanic general circulation and its associated mesoscale eddy field, have long been run separately in high-resolution global models. They are now being simu...
Modeling and Prediction of Internal Waves in the South China Sea
Modeling and Prediction Internal Waves South China Sea
2015/7/13
Nonlinear internal solitary waves generated within Luzon Strait move westward across the northern South China Sea, refract around Dongsha Atoll, and dissipate on the Chinese continental shelf after a ...
A Differential Equation for Modeling Nesterov’s Accelerated Gradient Method:Theory and Insights
Differential Equation Modeling Nesterov’s Accelerated Gradient Method
2015/7/8
We derive a second-order ordinary differential equation (ODE), which is the limit of Nesterov’s accelerated gradient method. This ODE exhibits approximate equivalence to Nesterov’s scheme and thus can...
Junction Modeling in Vehicle Navigation Maps and Multiple Representations
Cartography database generalization
2015/7/6
Generalization is certainly one of the most important current issues in cartography, with particular emphasis being placed on its
automation. This paper considers the automation of generalization app...
Aspects of Data Modeling of Fused Surfaces with Planimetric Data in a Topographic Geodatabase
Raster TIN Accuracy
2015/7/6
As a result of building a topological surfaced geodatabase for the test area, the paper discuses the investigation of modeling 3D
surface data, and its fusion with other planinmetric modeled data, an...
During the Global Ocean Data Assimilation Experiment (GODAE), numerical modeling and prediction in coastal and shelf seas benefited from development of state-of-the-art, data-assimilative, and data-va...
Influence of Teacher Support and Personal Relevance on Academic Self-Efficacy and Enjoyment of Mathematics Lessons: A Structural Equation Modeling Approach
academic self-efficacy learning environment
2015/7/6
The purpose of our study was to examine the effects of two psychosocial features of the classroom environment (teacher support and personal relevance) on college students’ academic self-efficacy and e...
Modeling Food Web Interactions in Benthic Deep-Sea Ecosystems
Deep-Sea Ecosystems Web Interactions
2015/7/3
Deep-sea benthic systems are notoriously difficult to sample. Even more than for other benthic systems, many
flows among biological groups cannot be directly measured, and data sets remain incomplete...
Computational modeling of deformation bands in granular media. I. Geological and mathematical framework
Deformation bands Granular media
2015/7/1
Failure of granular media under natural and laboratory loading conditions involves a variety of micromechanical processes producing several geometrically, kinematically, and texturally distinct types ...
Computational modeling of deformation bands in granular media. II. Numerical simulations
Deformation bands Granular media
2015/7/1
Development of accurate mathematical models of geomaterial behavior requires a more fundamental understanding of the localization phenomena; in particular, the important factors responsible for the in...
A finite-element (FE) model of localized deformation in soft rock taking a strong discontinuity approach is presented. The model is formulated within the context of rate-independent, nonassociated Dru...
