A Principled Methodology: A Dozen Principles Of Software Effort Estimation, Ekrem Kocaguneli
Graduate Theses, Dissertations, and Problem Reports (ETD)
Software effort estimation (SEE) is the activity of estimating the total effort required to complete a software project. Correctly estimating the effort required for a software project is of vital importance for the competitiveness of the organizations. Both under- and over-estimation leads to undesirable consequences for the organizations. Under-estimation may result in overruns in budget and schedule, which in return may cause the cancellation of projects; thereby, wasting the entire effort spent until that point. Over-estimation may cause promising projects not to be funded; hence, harming the organizational competitiveness.;Due to the significant role of SEE for software organizations, there is …

Training Individuals In Function-Based Behavior Intervention Plans Using Modeling, Rehearsal, And Self-Monitoring, Aimee F. Giles
Graduate Theses, Dissertations, and Problem Reports (ETD)
Behavior intervention plans based on the function of problem behavior are more likely to be effective than non-function-based plans. However, plans developed by teachers often do not address behavior function. In addition to ensuring that teachers can write function-based behavior intervention plans, it is also important to ensure plans are implemented with a sufficient degree of fidelity. The purpose of the present study was to evaluate a multi-component training package to train teachers to write function-based behavior intervention plans and to accurately implement differential reinforcement of alternative behavior for escape-maintained problem behavior. Twenty public school teachers of children with emotional …

Design And Evaluation Of A Marine Scrubber System, Louise S. Ayre
Graduate Theses, Dissertations, and Problem Reports (ETD)
Increasingly stringent oxides of nitrogen (NOX) emissions regulations for diesel marine engines are resulting in the development of newer engines with inherent NOX emissions reduction technologies. With typical useful service lives over 20 years, older diesel marine engines are producing disproportionate amounts of NOX emissions when compared with their newer counterparts. The development of retrofit exhaust aftertreatment technologies would therefore aid in reducing the total NOX emissions from these engines.;A marine scrubber system for the reduction of NOX emissions from diesel marine engines was designed, constructed, and evaluated. This work focused on gathering data for the design of a marine …

Onboard Parameter Identification For A Small Uav, Amanda K. Mcgrail
Graduate Theses, Dissertations, and Problem Reports (ETD)
One of the main research focus areas of the WVU Flight Control Systems Laboratory (FCSL) is the increase of flight safety through the implementation of fault tolerant control laws. For some fault tolerant flight control approaches with adaptive control laws, the availability of accurate post failure aircraft models improves performance. While look-up tables of aircraft models can be created for failure conditions, they may fail to account for all possible failure scenarios. Thus, a real-time parameter identification program eliminates the need to have predefined models for all potential failure scenarios. The goal of this research was to identify the dimensional …

An In Vitro Microenvironment For Nucleus Pulposus Regeneration, Mark S. Shoukry
An In Vitro Microenvironment For Nucleus Pulposus Regeneration, Mark S. Shoukry
Graduate Theses, Dissertations, and Problem Reports (ETD)
Intervertebral disc degeneration begins early in life, increases with age, and can ultimately result in disc failure. At the center of the disc, the nucleus pulposus (NP) resides in a hypoxic environment where degeneration is thought to begin. Initially, nucleus pulposus cells (NPCs) display altered morphology and function, along with increased rates of cellular senescence and apoptosis. Though no widely accepted treatment exists, autologous NP implantation techniques have shown promise. However, the process is flawed as a result of the long in vitro expansion required to obtain sufficient numbers of cells. Prolonged expansion on plastic produces negative changes such as …

Using The Concrete-Representational-Abstract Sequence To Connect Manipulatives, Problem Solving Schemas, And Equations In Word Problems With Fractions, Julie L. Reneau
Using The Concrete-Representational-Abstract Sequence To Connect Manipulatives, Problem Solving Schemas, And Equations In Word Problems With Fractions, Julie L. Reneau
Graduate Theses, Dissertations, and Problem Reports (ETD)
Students with learning disabilities or learning difficulties in mathematics often have difficulties solving word problems with fractions. These difficulties limit students' abilities to solve everyday math problems and develop the skills necessary for higher level mathematics. Prior research on problem solving indicates that direct instruction on problem schemas can improve problem solving performance. Previous research also suggests that instruction using the concrete-representational-abstract (CRA) sequence and instruction with virtual manipulatives can enhance understanding of mathematical concepts. However, a CRA sequence that incorporates virtual manipulatives has not been combined with schema-based instruction to help students solve word problems with fractions. The purpose …

The target formation for injection is the Early Cretaceous Donovan Sand of the Rodessa Formation, and is characterized by discontinuous fine- to medium-grained, heterogeneous arkosic fluvial sandstones interbedded with fissile mudstones and micaceous silts. Based upon core analysis of the Donovan Sand, depofacies indicate a fluvio-deltaic/estuarine depositional environment for the Donovan Sand. Probable sources of the …
Development And Testing Of A High Resolution Pet Detector For Prostate Imaging, Evan P. Delfino
Development And Testing Of A High Resolution Pet Detector For Prostate Imaging, Evan P. Delfino
Graduate Theses, Dissertations, and Problem Reports (ETD)
According to the American Cancer Society one in six men will be diagnosed with prostate cancer in their lifetime. Current methods for screening of prostate cancer including various PSA blood tests, as well as the digital rectal exam, are unreliability while current imaging modalities clinically employed (US, CT, MRI) are unable to localize intraprostatic cancer(s). Consequently, diagnosis via core needle biopsy is problematic and a game of chance at best. Therefore, in response to new radiopharmaceuticals applicable to both internal and external prostate cancer visualization and localization, novel prostate specific nuclear medical imagers are being developed.;The first prototype of a …
