For a bridge pier and abutment mass concrete project, three mixes were studied: an ordinary portland cement (OPC) mix (Type I PC) and two 70% by weight ground granulated blast furnace slag (GGBFS) mixes (Type II Low Heat PC). One of the slag mixes contained a high range water reducer (HRWR). Tests for compressive strength, freezethaw durability, rapid chloride permeability, and salt scaling were conducted on field samples. Results showed that the strengths of the slag mixes were lower than the OPC mix at all ages up to one year, although the use of HRWR did improve the strength somewhat. …


Ultrafiltration Membrane Process For Pyrogen Removal In The Preparation Of Water For Injection (Wfi), Thet N. Soe Jan 2006

Ultrafiltration Membrane Process For Pyrogen Removal In The Preparation Of Water For Injection (Wfi), Thet N. Soe

Inquiry: The University of Arkansas Undergraduate Research Journal

An artificial kidney process based on ultrafiltration (called hemodiafiltration) more effectively removes blood toxins, particularly those of higher molecular weight, than conventional dialysis. In hemodiafiltration, replacement liquid must be added directly to the patient's blood to replace liquid filtered out of the blood in the ultrafiltration cartridge. This replacement liquid is made up of' "water for injection" (WFI) and other components such as salts and glucose. WFI is produced either by distillation or reverse osmosis and has a cost of $1.00 per liter. A patient with kidney problems would require three hemodiafiltration treatments per week, each requiring 70-80 liters of …

In this paper, we theoretically prove that the corresponding successful biologically inspired formulas are indeed statistically optimal (in some reasonable sense).


Liquefaction Effects On Lateral Pile Behavior For Bridges, Wei Zheng, Ronaldo Luna Jan 2006

Liquefaction Effects On Lateral Pile Behavior For Bridges, Wei Zheng, Ronaldo Luna

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A coupled pile-soil-structure interaction (SPSI) analysis method is presented to study the liquefaction effects on lateral pile behavior of the highway bridges. Pile-soil interaction is simulated by the dynamic nonlinear p-y method including the effect of liquefaction. The liquefaction effects to the pile-soil interaction are taken into account by introducing a degradation multiplier to the p-y curve. The degradation multiplier is related to the excess pore water pressure buildup at the pile-soil interface. The SPSI analysis method is implemented into a Missouri highway bridge site near the New Madrid Seismic Zone (NMSZ) rift complex for future earthquake scenarios of Mw …


Object Association Across Multiple Moving Cameras In Planar Scenes, Yaser Sheikh Jan 2006

Object Association Across Multiple Moving Cameras In Planar Scenes, Yaser Sheikh

Electronic Theses and Dissertations

In this dissertation, we address the problem of object detection and object association across multiple cameras over large areas that are well modeled by planes. We present a unifying probabilistic framework that captures the underlying geometry of planar scenes, and present algorithms to estimate geometric relationships between different cameras, which are subsequently used for co-operative association of objects. We first present a local1 object detection scheme that has three fundamental innovations over existing approaches. First, the model of the intensities of image pixels as independent random variables is challenged and it is asserted that useful correlation exists in intensities of …


Polymer-Derived Si-Al-C-N Ceramics:Oxidation, Hot-Corrosion, And Structural Evolution, Yiguang Wang Jan 2006

Polymer-Derived Si-Al-C-N Ceramics:Oxidation, Hot-Corrosion, And Structural Evolution, Yiguang Wang

Electronic Theses and Dissertations

Polymer-derived ceramics are a new class of materials synthesized by thermal decomposition of polymer precursors. Previous studies have shown that the materials exhibit excellent thermo-mechanical properties and can be stable at temperatures up to 2000oC. Furthermore, the novel polymer-to-ceramics process enables the manipulation of the ceramic structures at the atomic/nano level by designing the chemistry of polymer precursors and controlling the pyrolysis conditions, thereby, the properties of ceramics. In this dissertation, oxidation/hot-corrosion behavior and the structural evolution of Si-Al-C-N ceramics have been studied. The structural evolution and crystallization behavior of the SiCN and SiAlCN ceramics are investigated using FT-IR, XRD, …


Unified Steady-State Computer Aided Model For Soft-Switching Dc-Dc Converters, Wisam Al-Hoor Jan 2006

Unified Steady-State Computer Aided Model For Soft-Switching Dc-Dc Converters, Wisam Al-Hoor

Electronic Theses and Dissertations

For many decades, engineers and students have heavily depended on simulation packages such as Pspice to run transit and steady-state simulation for their circuits. The majority of these circuits, such as soft switching cells, contain complicated modes of operations that require the Pspice simulation to run for a long time and, finally, it may not reach a convergent solution for these kinds of circuits. Also, there is a need for an educational tool that provides students with a better understanding of circuit modes of operation through state-plan figures and steady-state switching waveforms. The unified steady-state computer aided model proposes a …


A Derivation Of An Empirical Equation For Estimating The Acoustical Shadow Zone Length Of Roadway Noise Barriers, Wayne Arner Jan 2006

A Derivation Of An Empirical Equation For Estimating The Acoustical Shadow Zone Length Of Roadway Noise Barriers, Wayne Arner

Electronic Theses and Dissertations

The objective of this research was to derive an empirical equation that estimates the acoustical shadow zone length (SZL) of roadway noise barriers. The acoustical shadow zone is the area behind a noise barrier of reduced sound levels, generally to some stated level at or near background. The ability to predict the SZL can be used as a method to evaluate the performance, and possibly the design, of roadway noise barriers. The current federally required roadway noise model is the Federal Highway Administration (FHWA) Traffic Noise Model (TNM). TNM uses insertion loss (IL) to evaluate the effectiveness of a barrier. …

Creativity: A Framework For The Design/Problem Solving Discourse In Technology Education, Theodore Lewis Jan 2006

Creativity: A Framework For The Design/Problem Solving Discourse In Technology Education, Theodore Lewis

Publications

Subjects for which aesthetics and creative performance are critical curricular dimensions (such as art, physical education, music, and technology education), and which are accommodative of students across the range of intelligences (Gardner, 1999) are not readily or completely captured by content standards. Therefore content knowledge in these fields that target student achievement as conventionally conceived must be complemented by treatment of more subjective and elusive goals such as the development of connoisseurship, appreciation, or creative insight. With the publication of standards for the subject (International Technology Education Association, 2000), the need for focus upon creativity in technology education has been …
