Toward a comprehensive hazard-based duration framework to accomodate nonresponse in panel surveys
(2002)
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 ...
Seismic performance of full-scale reinforced concrete columns
(2005)
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 ...
Seismic analysis of a retrofitted reinforced concrete building in Mexico City
(2019-08-16)
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 ...
Sorption of selected endocrine disrupters by synthetic membrane vesicles and effects of natural organic matter
(2002-05)
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 ...
Modeling carrier collaboration in freight networks
(2009-08)
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 ...
A proposed system for evaluating consultant PS & E performance
(2004-05-22)
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 ...
Development and implementation of an engineering productivity measurement system (EPMS) for benchmarking
(2007)
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 ...
Impact of emerging water scenarios on performance of urban water networks
(2018-05-04)
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 ...
Applying the PDRI in project risk management
(2002)
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 ...
Developing a GIS-based traffic control planning tool
(2009-12)
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 ...
