Application of GNSS for Vertical Reference Determination

Creator:: Kim, Su-Kyung
Abstract:: Vertical datum is a reference system used for specifying the elevation of specific points on or near the Earth. Precise and accurate definition and realization of vertical references are, therefore, crucial to ensure consistency between height measurements. The vertical datums can be divided into two categories: 1) vertical geodetic datums...

Mass transport in laboratory water wave flumes

Creator:: Kim, Tae In
Abstract:: A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

Response Sensitivity Formulations for Geometrically Nonlinear Finite Element Analysis

Creator:: Al-Aukaily, Alabbas
Abstract:: Significant amounts of uncertainty owing to both modeling decisions and inherent randomness are present in simulating the material and geometric nonlinear response of structural systems to extreme loading. Computing the sensitivity of structural response with respect to model parameters indicates which parameters have the largest affect on the response, which...

Durability and Performance of High Early Strength Concrete for Structural Bridge Deck Overlays

Creator:: Smith, Jeremy A.
Abstract:: High early strength concrete (HESC) allows for faster construction with less impact on traffic, thus reducing the indirect costs associated with a project. There are multiple methods for achieving early strength, such as alternative cements like calcium sulfoaluminate (CSA) or chemically accelerated portland cements. The standard criteria for an HESC...

An eigenvalue wave analysis of a fixed semi-immersed rectangular structure

Creator:: Steimer, Robert Bruce
Abstract:: The problem of a fixed rectangular structure of unit width in a train of simple harmonic normally-incident waves is modeled. The solution allows for variable (1) length and draft of structure, (2) differing depths in the three (fore, aft, and beneath the structure) distinct regions, and (3) wave period. The...

The Effects of Construction Practices on Concrete Construction Joint Performance

Creator:: Panduranga Setty, Shreyas
Abstract:: Concrete is the most widely used construction material in the world. When constructing large concrete structures, concrete may have to be placed in multiple lifts. In these cases, fresh concrete is placed on hardened concrete. The interface that is formed between these two lifts of concrete is known as a...

Kinetic and modeling investigations of the anaerobic reductive dechlorination of chlorinated ethylenes using single and binary mixed cultures and silicon-based organic compounds as slow-release substrates

Creator:: Yu, Seungho
Abstract:: This study investigated complete reductive dechlorination of chlorinated aliphatic hydrocarbons (CAHs) over a broad range of concentrations. Tetrabutoxysilane (TBOS), as a slow-release anaerobic substrate, was studied for enhanced reductive dechlorination of tetrachioroethylene (PCE) present as a dense non-aqueous liquid (DNAPL). Four different site-mixed cultures were used in the study: Site-300...

Inhibition, kinetic and modeling studies of acetylene and 1-chloro-1-fluoroethene on reductive dechlorination of TCE and vinyl chloride

Creator:: Pon, George
Abstract:: Laboratory and modeling studies were performed with a mixed-anaerobic-culture obtained from the Evanite site in Corvallis, Oregon. The culture completely transforms trichloroethene (TCE) to cis-dichloroethene (c-DCE), vinyl chloride (VC), and finally to ethene. Acetylene inhibition studies were used to examine the culture's microbial activities. Kinetic studies determined the half-saturated constant...

Automated Monitoring of Construction Operations for Data-Driven Decision Making

Creator:: Rashid, Khandakar, M.
Abstract:: The continuous improvement of construction operations requires a systematic approach of monitoring and making appropriate control actions. However, the lack of real-time information hinders this workflow and eventually compromises timely and effective decision-making. Project managers spend a great deal of time and effort to solve problems emerging from lack of...
