Many surveys suffer from low response rates and therefore carry a risk of nonresponse bias. The problem is more severe in panel surveys because sample units are subject to nonresponse repeatedly. This dissertation is ...

The deformation capacity of a concrete column can be expressed by using different ductility parameters such as curvature ductility, displacement ductility or drift capacity. However, little research has been conducted ...

This thesis presents a study on the dynamic characteristics and seismic performance of a retrofitted concrete building located in the soft soil area of Mexico City. The original structure consisted of reinforced concrete ...

In this study, synthetic membrane vesicles (liposomes) were prepared from phospholipids and cholesterol as a model biological phase, and the bioavailability of four estrogens and five estrogenic compounds were evaluated ...

This work presents two mechanisms for modeling alliance formation between leader carriers in a freight network for more efficient utilization of their resources: partial collaboration and complete collaboration. The ...

Consultant performance on PS&E projects oftentimes adversely impacts timely completion of TxDOT highway projects. TxDOT's ability to quickly and effectively choose well-qualified, capable consulting firms for executing new ...

Reliable engineering productivity measurement is a critical element of predictable project performance and continuous improvement. Despite the fact that engineering costs have risen to levels approaching 20 percent of total ...

Concerns over the impacts of urban growth have prompted the development and adoption of water-demand management strategies. Water and energy savings from increasingly efficient technologies, diversified water sources, and ...

Research conducted by the Construction Industry Institute (CII) shows that adequate pre-project planning benefits project in the areas of cost, schedule, and operational characteristics. Pre-project planning is the project ...

The purpose of this study is to assist TxDOT engineers in the field of traffic control planning. This is to be done via the creation of a Geographic Information System (GIS) based tool. By bringing together information ...
