RISReal-Time Occlusion Handling for Dynamic Augmented Reality Using Geometric Sensing and Graphical Shading
Publisher: American Society of Civil Engineers
Abstract: The primary challenge in generating convincing augmented reality (AR) graphics is to project three-dimensional (3D) models onto a user’s view of the real world and create a temporal and spatial sustained illusion that the ...
Correlated Random Parameter Marginalized Two-Part Model: Application to Refined-Scale Longitudinal Crash Rates Data
Publisher: American Society of Civil Engineers
Abstract: Crash rate data are mainly analyzed using the Tobit model. However, there are three major limitations associated with the Tobit model when it is applied to crash data: (1) the assumption that zeros are originated from ...
Evaluation and Improvement of the Interchange from Bus to Metro Using Smart Card Data and GIS
Publisher: American Society of Civil Engineers
Abstract: The ridership of a metro system depends largely on the feed from other modes, especially buses. Therefore the quality of the interchange between metro and buses is a significant factor affecting the attractiveness of a ...
Fully Coupled Model for One-Dimensional Large-Strain Consolidation and Heat Conduction in Saturated Clay
Publisher: American Society of Civil Engineers
Abstract: The consolidation characteristics of soils are affected by both mechanical loading and ambient temperature. However, research on this coupled theory is lacking. In this study, a fully coupled model for one-dimensional ...

Urbanization Effect on the Diurnal Temperature Range: Different Roles under Solar Dimming and Brightening
Publisher: American Meteorological Society
Abstract: ased on the 1960?2009 meteorological data from 559 stations across China, the urbanization effect on the diurnal temperature range (DTR) was evaluated in this study. Different roles of urbanization were specially detected ...
Cloud Classification Based on Structure Features of Infrared Images
Publisher: American Meteorological Society
Abstract: Some cloud structure features that can be extracted from infrared images of the sky are suggested for cloud classification. Both the features and the classifier are developed over zenithal images taken by the whole-sky ...
Axial Compressive Behavior of Thin-Walled Concrete-Filled Double-Skin Steel Tubular Stub Columns with Connecting Strips
Publisher: ASCE
Abstract: Concrete-filled double-skin tubular (CFDST) columns have high fire resistance, and are widely used in the construction of electrical towers and bridges. However, previous research showed that the buckling of steel tubes ...
Mechanical Performance of Circular Ultrahigh-Performance Concrete–Filled Double Skin High-Strength Steel Tubular Stub Columns under Axial Compression
Publisher: ASCE
Abstract: This paper proposed a new type of stiffened circular ultra-high performance concrete-filled double skin steel tubular (UHPCFDST) column, in which stiffeners were applied to connect both inner and outer steel tubes. It ...
Investigation on One-Dimensional Nonlinear Thermal Consolidation of Saturated Clay under the Impeded Drainage Boundary
Publisher: ASCE
Abstract: Temperature changes affect the nonlinear consolidation process in soils, and there is limited associated theoretical research. In this study, the governing equations for nonlinear consolidation and thermal conduction are ...
