Risk Assessment for Bridge Maintenance Projects: Neural Networks versus Regression Techniques
(American Society of Civil Engineers, 2007)Bridge risk assessment often serves as the basis for bridge maintenance priority ranking and optimization and conducted periodically for the purpose of safety. This paper presents an application of artificial neural networks ... -
Synthesis and Validation of High-Level Behavior Models for Narrow Waterway Management Systems
(American Society of Civil Engineers, 2007)This note describes the essential features of a new methodology for the incremental transformation of informal operations concepts for a waterway management system into system-level designs, the latter being formal enough ... -
Developments in Coarse-Grain Modeling of Transient Heat-Flow in Buildings
(American Society of Civil Engineers, 2007)The note reports on recent developments to the coarse-grain method (CGM) of modeling transient heat flow in buildings. CGM was originally developed as an alternative to conventional fine-grain modeling techniques [such as ... -
Computer-Aided Healthcare Facility Management
(American Society of Civil Engineers, 2007)The decision-making process in the field of health-care facility management is multifaceted and encompasses many different areas, including maintenance, performance, risk, operations, and development. Information and ... -
Development and Evaluation of a Vehicle-Infrastructure Integration Simulation Architecture
(American Society of Civil Engineers, 2007)Advances in information technology are making the close integration of vehicles and the infrastructure in the surface-transportation system feasible. In particular, one approach to this integration receiving significant ... -
Modeling the Effect of Topography on Wind Flow Using a Combined Numerical–Neural Network Approach
(American Society of Civil Engineers, 2007)The impact of topography on design wind speed is addressed in current building codes and design standards by providing “speed-up” ratios for limited cases of terrain geometries. This paper proposes a combined numerical–neural ... -
Engineering Analysis with Uncertainties and Complexities, Using Reasoning Approaches
(American Society of Civil Engineers, 2007)Conventional computation methods generally limit practicing engineers from using complex formulations or considering uncertainties in general. A method is needed that can be implemented regardless of the uncertainty or ... -
Construction Planning Method Using Case-Based Reasoning (CONPLA-CBR)
(American Society of Civil Engineers, 2007)During the construction process, there occur many unexpected events that hinder timely completion of a project. One plausible solution in formulating a robust plan against such uncertainties is to provide the proper ... -
Georeferenced Registration of Construction Graphics in Mobile Outdoor Augmented Reality
(American Society of Civil Engineers, 2007)This paper describes research that investigated the application of the global positioning system and 3 degree-of-freedom (3-DOF) angular tracking to address the registration problem during interactive visualization of ... -
Application of Support Vector Machines in Assessing Conceptual Cost Estimates
(American Society of Civil Engineers, 2007)Total conceptual cost estimates and the assessment of the quality of these estimates are critical in the early stages of a building construction project. In this study, the support vector machine (SVM) model for assessing ... -
Using Hue, Saturation, and Value Color Space for Hydraulic Excavator Idle Time Analysis
(American Society of Civil Engineers, 2007)Accurate analyses of equipment idle time are crucial for the efficient utilization of construction equipment in large construction projects. The less idle time the equipment has, the higher productivity it can achieve. ... -
Formalism for Detecting Version Differences in Data Models
(American Society of Civil Engineers, 2007)In the architecture/engineering/construction (AEC) industry, a large number of data models (e.g., data exchange standards and task-specific data models) have been created and utilized to represent and exchange data in ... -
Developing Complete Conditional Probability Tables from Fractional Data for Bayesian Belief Networks
(American Society of Civil Engineers, 2007)A Bayesian belief network (BBN) can be a powerful tool in decision making processes. Development of a BBN requires data or expert knowledge to assist in determining the structure and probabilistic parameters in the model. ... -
Evaluation of Augmented Reality for Rapid Assessment of Earthquake-Induced Building Damage
(American Society of Civil Engineers, 2007)This paper discusses the feasibility of using augmented reality (AR) to evaluate earthquake-induced building damage. In the proposed approach, previously stored building information is superimposed onto a real structure ... -
Capturing Implicit Structures in Unstructured Content of Construction Documents
(American Society of Civil Engineers, 2007)In a paper-based paradigm, whether construction information is presented in structured or unstructured format is not a critical issue because human beings are good at processing both types of information. However, the ... -
End-User Attitudes toward EDM Use in Construction Project Work: Case Study
(American Society of Civil Engineers, 2007)This paper reports on a cross-sectional case study of a large construction project in which electronic document management (EDM) was used. Attitudes toward EDM from the perspective of individual end-users were investigated. ... -
Hybrid Genetic Programming with Local Search Operators for Dynamic Force Identification
