An Object-oriented Framework for Spatial Interpolation

Yo-Ming Hsieh, and Mao-Sen Pan
Pages 527-534

Abstract: Interpolation is an important operator in numerical methods for solving partial differential equations and in geospatial applications. There are many interpolation methods proposed in the past. In this work, a unified software framework is proposed through the use of design-patterns in object-oriented programming. By using this framework, little effort is ...

Sparse Reconstruction and Geo-Registration of Site Photographs for As-Built Construction Representation and Automatic Progress Data Collection

Mani Golparvar-Fard, Feniosky Peña-Mora and Silvio Savarese
Pages 535-543

Abstract: Most of the current techniques for automating progress data collection promise to eliminate laborintensive tasks associated with manual data collection. A drawback is the necessity to add additional steps to be performed before, during, or after utilization of such technologies. Working with such featureless data and without having semantic information ...

Dynamic Simulation for Assessment of Impact of Highway Lane Closure on Traffic

Seokyon Hwang
Pages 562-569

Abstract: Improvement of existing highway systems, such as maintenance, rehabilitation, and reconstruction, is accompanied with lane closure at work zones. Such lane closure causes road user costs for traffic congestion and delays at the work zones. A robust method is developed in this research to support strategic decisionmaking on lane closures. ...
