Recommendations For Improvement Of Collegiate Flight Training Operational Efficiency Through Guided-Inquiry Inductive Learning, John H. Mott, Darcy M. Bullock

International Journal of Aviation, Aeronautics, and Aerospace

Efficiency in higher education has increasingly come under scrutiny as student debt levels continue to increase and the quantification of the value provided to students by colleges remains elusive. Collegiate flight training operations are especially subject to such scrutiny, due to their expense and to continued below-average entry-level salaries in the airline industry. This research examines an inductive learning approach combined with a flipped classroom, whereby aviation management students in a large Midwestern collegiate aviation program analyzed the operational efficiency of their primary flight training operation and recommend potential solutions and means of implementation. Such an approach provides multiple benefits. …

Embedded System Design Of A Real-Time Parking Guidance System, Omkar Dokur

USF Tampa Graduate Theses and Dissertations

The primary objective of this work is to design a parking guidance system to reliably detect entering/exiting vehicles to a parking garage in a cost-efficient manner. Existing solutions (inductive loops, RFID based systems, and video image processors) at shopping malls, universities, airports etc., are expensive due to high installation and maintenance costs. There is a need for a parking guidance system that is reliable, accurate, and cost-effective. The proposed parking guidance system is designed to optimize the use of parking spaces and to reduce wait times. Based on a literature review we identify that the ultrasonic sensor is suitable to …

Modeling Intrastate Air Travel: A Case Study Of The State Of Florida, Kai Liao

USF Tampa Graduate Theses and Dissertations

Florida is a state in the southeastern region of the United States. Its infrastructure allows for several travel modes including: rail, automobile, bus, aircraft, and ship. However, most intrastate travelers in Florida are limited to two practical choices: travel by car (ground mode) or travel by air (air primary mode). Due to the dramatic growth of Florida’s population over recent years, traffic has become a critical factor that impacts Florida’s development. This thesis focuses on intrastate air primary mode and develops decision making models that could aid government and airline companies to better understand travelers need and as such plan …

When You Say Nothing At All: The Predictive Power Of Student Effort On Surveys, Collin Hitt

Education Reform Faculty and Graduate Students Publications

Character traits and noncognitive skills are important for human capital development and longrun life outcomes. Research in economics and psychology now shows this clearly. But research into the exact determinants of noncognitive skills have been slowed by a common data limitation: most large-scale datasets do not contain adequate measures of noncognitive skills. This is a particularly acute problem in education policy evaluation. We demonstrate that there are important latent data within any survey dataset that can be used as proxy measures of noncognitive skills. Specifically, we examine the amount of conscientious effort that students exhibit on surveys, as measured by …

On The Stability Of Cycles By Delayed Feedback Control, Dmitriy Dmitrishin, Paul Hagelstein, Anna Khamitova, Alexander M. Stokolos

Mathematical Sciences: Faculty Publications

We present a delayed feedback control (DFC) mechanism for stabilizing cycles of one dimensional discrete time systems. In particular, we consider a delayed feedback control for stabilizingT-cycles of a differentiable functionf:R→Rof the form

x(k+1)=f(x(k))+u(k)

where

u(k)=(a₁−1)f(x(k))+a₂f(x(k−T))+...+a_Nf(x(k−(N−1)T)),

with a₁+...+a_N=1. Following an approach of Morgül, we construct a map F:R^T+1→R^T+1 whose fixed points correspond to T-cycles of f. We then analyze the local stability of the above DFC mechanism by evaluating the stability of the corresponding equilibrum points of F. We associate to each periodic orbit of f an …

Building A Culture Of Hope For Youth At Risk: Supporting Learners With Optimism, Place, Pride, And Purpose, Emily L. Gibson, Robert D. Barr

National Youth Advocacy & Resilience Journal

A Culture of Hope provides a blueprint for schools wanting to meet the social/emotional needs of youth placed at risk. While the importance of meeting students’ social/emotional needs is clearly supported in the literature and in the media, teachers and administrators may need help in determining where and how to start. This essay introduces the Culture of Hope, provides an overview of the four Seeds of Hope, and shares links to student and staff surveys as well as methods for analyzing surveys to reveal student and staff needs.

Changes In Litter Quality Caused By Simulated Nitrogen Deposition Reinforce The N-Induced Suppression Of Litter Decay, Linda T. A. Van Diepen, Serita D. Frey, Christopher M. Sthultz, Eric W. Morrison, Rakesh Minocha, Anne Pringle

Faculty Publications

Rates of nitrogen (N) deposition are increasing in industrialized and rapidly developing nations. Simulated N deposition suppresses plant litter decay rates, in particular for low quality (high lignin) litter. Litter quality is a primary driver of litter decomposition; however, it is not clear how changes in litter quality caused by long-term ecosystem exposure to chronic N additions interact with altered soil N-availability to influence litter decay dynamics. To document the effects of simulated N deposition on litter quality, we conducted a meta-analysis of available litter nutrient data from simulated N deposition experiments in temperate forests. To directly test whether changes …

Tailoring The Pore Environment Of Metal-Organic And Molecular Materials Decorated With Inorganic Anions: Platforms For Highly Selective Carbon Capture, Patrick Stephen Nugent

USF Tampa Graduate Theses and Dissertations

Due to their high surface areas and structural tunability, porous metal-organic materials, MOMs, have attracted wide research interest in areas such as carbon capture, as the judicious choice of molecular building block (MBB) and linker facilitates the design of MOMs with myriad topologies and allows for a systematic variation of the pore environment. Families of MOMs with modular components, i.e. MOM platforms, are eminently suitable for targeting the selective adsorption of guest molecules such as CO₂ because their pore size and pore functionality can each be tailored independently. MOMs with saturated metal centers (SMCs) that promote strong yet reversible …

Prediction Of The Optimum Binder Content Of Open-Graded Friction Course Mixtures Using Digital Image Processing, Yolibeth Mejias De Pernia

USF Tampa Graduate Theses and Dissertations

Florida Department of Transportation (FDOT) has been using Open Graded Friction Course (OGFC) mixture to improve skid resistance of asphalt pavements under wet weather. The OGFC mixture design strongly depends on the Optimum Binder Content (OBC) which represents if the mixture has sufficient bonding between the aggregate and asphalt binder. At present, the FDOT designs OGFC mixtures using a pie plate visual draindown method (FM 5-588). In this method, the OBC is determined based on visual inspection of the asphalt binder draindown (ABD) configuration of three OGFC samples placed on pie plates with pre-determined trial asphalt binder contents (AC). The …

Developing A Compiler For A Regular Expression Based Policy Specification Language, Cory Michael Juhlin

USF Tampa Graduate Theses and Dissertations

Security policy specification languages are a response to today's complex and vulnerable software climate. These languages allow an individual or organization to restrict and modify the behavior of third-party applications such that they adhere to the rules specified in the policy. As software grows in complexity, so do the security policies that govern them. Existing policy specification languages have not adapted to the growing complexity of the software they govern and as a result do not scale well, often resulting in code that is overly complex or unreadable. Writing small, isolated policies as separate modules and combining them is known …

Saharan Air Layer Dust Loading: Effects On Convective Strength In Tropical Cloud Clusters, Randall J. Hergert

USF Tampa Graduate Theses and Dissertations

Numerous factors play a role in the development and maintenance of North Atlantic tropical cyclones as they originate and cross the Main Development Region. These factors include sea-surface temperatures (SSTs), relative humidity, vertical wind shear, etc. One key player in many of these factors is the Saharan Air Layer (SAL) which has been a source for study for nearly five decades.

The interplay between dust loading within the SAL and the development of African Easterly Waves (AEWs) has been repeatedly noted in many of the studies in this field. The cumulative indirect effect of the dust on AEWs however remains …

Measuring Polydimethylsiloxane (Pdms) Mechanical Properties Using Flat Punch Nanoindentation Focusing On Obtaining Full Contact, Federico De Paoli

USF Tampa Graduate Theses and Dissertations

In this research, the materials used were the Polydimethylsiloxane (PDMS) polymers. PDMS mechanicals properties were measured using a customized version of the nanoindentation test using a flat punch tip. The method is proposed in Chapter 3 and it is used to calculate the elastic modulus of different PDMS samples. The samples tested were both produced specifically for this research and available in the laboratory’s storage. They all present different levels of cross-linking degree.

It is quite common to not have full contact between the cylindrical flat punch and the sample because of the unavoidable tilt. The new method guarantees establishing …

Removing Inter-Subject Technical Variability In Magnetic Resonance Imaging Studies, Jean-Philippe Fortin, Elizabeth M. Sweeney, John Muschelli, Ciprian M. Crainiceanu, Russell T. Shinohara, Alzheimer’S Disease Neuroimaging Initiative

UPenn Biostatistics Working Papers

Magnetic resonance imaging (MRI) intensities are acquired in arbitrary units, making scans non-comparable across sites and between subjects. Intensity normalization is a first step for the improvement of comparability of the images across subjects. However, we show that unwanted inter-scan variability associated with imaging site, scanner effect and other technical artifacts is still present after standard intensity normalization in large multi-site neuroimaging studies. We propose RAVEL (Removal of Artificial Voxel Effect by Linear regression), a tool to remove residual technical variability after intensity normalization. As proposed by SVA and RUV [Leek and Storey, 2007, …

Running And Tumbling With E. Coli In Polymeric Solutions, Alison E. Patteson, Arvind Gopinath, Mark Goulian, Paulo E. Arratia

Physics - All Scholarship

Run-and-tumble motility is widely used by swimming microorganisms including numerous prokaryotic and eukaryotic organisms. Here, we experimentally investigate the run-and-tumble dynamics of the bacterium E. coli in polymeric solutions. We find that even small amounts of polymer in solution can drastically change E. colidynamics: cells tumble less and their velocity increases, leading to an enhancement in cell translational diffusion and a sharp decline in rotational diffusion. We show that suppression of tumbling is due to fluid viscosity while the enhancement in swimming speed is mainly due to fluid elasticity. Visualization of single fluorescently labeled DNA polymers reveals that the …

Essays On Auctions And Mechanism Design., Abdul Quadir Dr.

Doctoral Theses

This thesis consists of three chapters that aim to characterize incentive compatible mechanisms in specific mechanism design settings. In these settings, the designer is allowed to use payments but the net utility of every agent is linear in payments. This particular assumption on net utility is called quasi-linearity. Each of the three chapters in the thesis identifies a class of mechanisms and characterizes them (in quasilinear private value environment) using dominant strategy incentive compatibility and some additional reasonable conditions.In quasi-linear environment, a mechanism can be decomposed into an allocation rule and a payment rule for every agent. If a mechanism …

The Softwood Sawtimber Stumpage Market In Louisiana: Market Dynamics, Structural Break, And Vector Error Correction Model, Rajan Parajuli, Sun Joseph Chang

Faculty Publications

This study estimates simultaneous demand and supply equations for the softwood sawtimber stumpage market in Louisiana using Johansen’s multivariate time-series analysis. The cointegration test in the presence of structural breaks is used to identify the rank of the long-run cointegrating space, and normalization restrictions are imposed to specify demand and supply models under the framework of the vector error correction model. Based on the annual data series from 1955 to 2013, the results reveal that long-run demand and supply coefficient estimates are statistically significant with expected signs. The pine beetle outbreaks in 1985–1986, the timber harvest reductions in the Pacific …
