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 ...
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 ...
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 ...
Acoustic emission signature analysis of failure mechanisms in fiber reinforced plastic structures
(2002)
The objective of the research program was to develop reliable pattern
recognition and neural network analysis methods to determine the failure
mechanism signatures in fiber reinforced plastic structures from acoustic ...
Composite structural members for short span highway bridges
(2002)
This research focused on the development of a structural system
composed of a reinforced concrete (RC) deck and fiber reinforced plastic
(FRP) girders and arches. The deck and the girders were designed to carry
the load ...
Top-lateral bracing systems for trapezoidal steel box-girder bridges
(2002)
Trapezoidal steel box girders are becoming increasingly popular as a
bridge system due to their torsional efficiency and aesthetic appearance. These
bridge systems utilize one or more trapezoidal steel girders with a ...
Integrated water treatment: softening and ultrafiltration
(2002)
Integrated water treatment with softening and ultrafiltration is proposed as
a promising option for hard waters, as a means to balance risks from
microorganisms and disinfection/disinfectant by-products in drinking ...
Determination of soil properties from earthquake data
(2002-05)
Soil damping and site (system) dominant vibration frequency estimations
were obtained by means of the Random Decrement Method (RDM) using
numerically simulated time series of soil model responses upon random
excitations ...
