Innovative Contracting Prequalification/Selection Model Using Analytical Hierarchy Process (Ahp), Saad J. Zidan

Masters Theses

Design-Build, Cost-Plus-Time, and warranty are the three innovative contracting methods that the Federal Highway Administration (FHWA) decided to fund. FHWA allowed the usage of these methods in federally funded projects if this will result in reducing time, improving quality, and saving tax payers' money. Prequalification is recognized as the best way of assuring that contractors do have the required qualifications to deliver projects successfully. Prequalification is even more critical when low-bid selection method is used with any of the innovative contracting, since incompetent contractors may get awarded for low-bids that are not based on valid assumptions.

Influence Of Isoflurane On Left Atrial Function In Dogs With Pacing-Induced Cardiomyopathy: Evaluation With Pressure-Volume Relationships, Franz Kehl, John F. Ladisa, Douglas Anthony Hettrick, Judy R. Kersten, David C. Warltier, Paul S. Pagel

Biomedical Engineering Faculty Research and Publications

Objective

The actions of volatile anesthetics on left ventricular (LV) function in normal and failing hearts have been previously evaluated, but the effects of these agents on left atrial (LA) function in the presence of LV dysfunction are unknown. The hypothesis was tested that isoflurane alters LA mechanics evaluated with pressure-volume relations.

Design

Prospective.

Setting

Laboratory.

Participants

Barbiturate-anesthetized dogs (n = 8) were instrumented for measurement of aortic, LA, and LV pressures (micromanometers), and LA volume (epicardial orthogonal sonomicrometers) after 3 weeks of rapid ventricular pacing (220 beats/min).

Interventions

LA myocardial contractility (E_es) was assessed with end-systolic pressure-volume …

The Stromal Cell-Derived Factor-1alpha/Cxcr4 Ligand-Receptor Axis Is Critical For Progenitor Survival And Migration In The Pancreas., Ayse G. Kayali, Kurt Van Gunst, Iain L. Campbell, Aleksandr Stotland, Marcie Kritzik, Guoxun Liu, Malin Flodström-Tullberg, You-Qing Zhang, Nora Sarvetnick

Journal Articles: Regenerative Medicine

The SDF-1alpha/CXCR4 ligand/chemokine receptor pair is required for appropriate patterning during ontogeny and stimulates the growth and differentiation of critical cell types. Here, we demonstrate SDF-1alpha and CXCR4 expression in fetal pancreas. We have found that SDF-1alpha and its receptor CXCR4 are expressed in islets, also CXCR4 is expressed in and around the proliferating duct epithelium of the regenerating pancreas of the interferon (IFN) gamma-nonobese diabetic mouse. We show that SDF-1alpha stimulates the phosphorylation of Akt, mitogen-activated protein kinase, and Src in pancreatic duct cells. Furthermore, migration assays indicate a stimulatory effect of SDF-1alpha on ductal cell migration. Importantly, blocking …

Disasters And Energy Security Management, Florida Solar Energy Center, William Young

FSEC Energy Research Center®

In the past, natural disasters, such as hurricanes, floods, tornados, and earthquakes, were one of our major concern. Now, terrorist events are becoming more common and more destructive. Whether, natural or man made, a disaster can happen at any time, often with little or no advance warning. A disaster can leave many people without adequate medical services, potable water, electrical service and communications for long periods of time. They can be as destructive as Hurricane Mitch leaving several hundred-thousand people homeless or as minor as an afternoon thunderstorm knocking down local power lines to your home. Not only can lives …

Converting Plant Biomass To Fuels And Commodity Chemicals In South Africa: A Third Chapter?, L R. Lynd, H H Von Blottnitz, B Tait, J De Boer, I S. Pretorius, K Rumbold, W H. Van Zyl

Dartmouth Scholarship

There have been two distinct chapters in the history of converting cellulosic biomass to fuels and commodity chemicals in South Africa. The first chapter, fromthe late 1970s to the early 1990s, involved some of the most active research and development efforts of their kind anywhere in the world. Thereafter, during the second chapter, there has been very little activity in the field in South Africa while there has been an unprecedented awakening to the potential of biomass conversion elsewhere. This paper considers the rationale and possible benefits of a potential third chapter based on a revitalized effort on biomass conversion …

Kalman Filtering For Fuzzy Discrete Time Dynamic Systems, Daniel J. Simon

Electrical and Computer Engineering Faculty Publications

This paper uses Kalman filter theory to design a state estimator for noisy discrete time Takagi–Sugeno (T–S) fuzzy models. One local filter is designed for each local linear model using standard Kalman filter theory. Steady state solutions can be found for each of the local filters. Then a linear combination of the local filters is used to derive a global filter. The local filters are time-invariant, which greatly reduces the computational complexity of the global filter. The global filter is shown to be unbiased and (under certain conditions) stable. In addition, under the approximation of uncorrelatedness among the local models, …

The Effects Of Nationality In The Intercultural Relationship In A Maquila Environment, Cultural Dimensions A Practical Approach, Daniel Martin Reynoso Ortiz

Theses and Dissertations - UTB/UTPA

The Maquiladora Industry has enhanced economic development in the U.S. and Mexico border region. Initially, investors came to set up assembly lines requiring a small amount of technical skill; however, increases in the technological level of products have created the need for companies to require more technical expertise from their staff. Today, the requirement is for the design or redesign of some of their products and the manufacturing processes required to make these products. This brings managerial problems in dealing with technical people in cross cultural environments. These problems deal with staffing issues such as getting the right people and …

Melanoma And Seborrheic Keratosis Differentiation Using Texture Features, Srinivas V. Deshabhoina, Scott E. Umbaugh, William V. Stoecker, Randy Hays Moss, Subhashini K. Srinivasan

Chemistry Faculty Research & Creative Works

Purpose: To explore texture features in two-dimensional images to differentiate seborrheic keratosis from melanoma.

Methods: A systematic approach to consistent classification of skin tumors is described. Texture features, based on the second-order histogram, were used to identify the features or a combination of features that could consistently differentiate a malignant skin tumor (melanoma) from a benign one (seborrheic keratosis). Two hundred and seventy-one skin tumor images were separated into training and test sets for accuracy and consistency. Automatic induction was applied to generate classification rules. Data analysis and modeling tools were used to gain further insight into the feature space. …

However no significant correlation was found between the fluoride release and the antibacterial activity.

Interpreting Hemoglobin And Water Concentration, Oxygen Saturation, And Scattering Measured In Vivo By Near-Infrared Breast Tomography, Subhadra Srinivasan, Brian W. Pogue, Shudong Jiang, Hamid Dehghani, Christine Kogel, Sandra Soho, Jennifer J. Gibson, Tor D. Tosteson, Steven P. Poplack, Keith D. Paulsen

Dartmouth Scholarship

Near-infrared spectroscopic tomography was used to measure the properties of 24 mammographically normal breasts to quantify whole-breast absorption and scattering spectra and to evaluate which tissue composition characteristics can be determined from these spectra. The absorption spectrum of breast tissue allows quantification of (i) total hemoglobin concentration, (ii) hemoglobin oxygen saturation, and (iii) water concentration, whereas the scattering spectrum provides information about the size and number density of cellular components and structural matrix elements. These property data were tested for correlation to demographic information, including subject age, body mass index, breast size, and radiographic …

Evaluation Of Methods To Protect Water Quality In Karst Areas: Phase I, Jennifer Webster, Dhandayudhapani Ramalingam, Sudhir Palle

Kentucky Transportation Center Research Report

The primary focus of this report is two-fold; to provide a literature review on what has been previously learned about highway runoff in relation to karsts aquifers and to characterize a karsts highway site in Kentucky that can be used to evaluate a variety of best management practices. From research findings, the main sources of pollutants in highway runoff came from vehicles, atmospheric fallout, and precipitation. The behavior of pollutants and their interaction with the environment can dictate where they will be found and how to best minimize their effects. Although it would seem that traffic volumes would greatly influence …

Winter Operations, Abrasives And Salt Brine, Geza Pesti, Yu Liu

Nebraska Department of Transportation: Research Reports

The primary objective of winter maintenance operations is to improve traffic safety and efficiency during winter storm periods. Abrasives and salt brines have been successfully applied to increase traction and prevent snow and ice from bonding to road surface. However, because of some undesired side effects, such as corrosion and damage to the environment, salt and abrasives may need to be supplemented by other substances in some areas. Powerful non-corrosive acetate-based chemicals have been considered by several agencies, but their high price has limited their use. Recent research has focused on the use of new, less corrosive, and highly effective …
