Investigating The Universality And Comprehensive Ability Of Measures To Assess The State Of Workload, Julian Abich
Investigating The Universality And Comprehensive Ability Of Measures To Assess The State Of Workload, Julian Abich
Electronic Theses and Dissertations
Measures of workload have been developed on the basis of the various definitions, some are designed to capture the multi-dimensional aspects of a unitary resource pool (Kahneman, 1973) while others are developed on the basis of multiple resource theory (Wickens, 2002). Although many theory based workload measures exist, others have often been constructed to serve the purpose of specific experimental tasks. As a result, it is likely that not every workload measure is reliable and valid for all tasks, much less each domain. To date, no single measure, systematically tested across experimental tasks, domains, and other measures is considered a …
The Rise Of Asia's Democratic Space Powers How Japan And India Became The Next Space Powers In The Twenty-First Century, Shane Kunze
HIM 1990-2015
Since the end of World War II the world has seen several nations expand into the space age. Also after the Second World War, the Cold War began and many nations found themselves allying themselves with either the hegemony of the West or the Communists. Space was no exception in this dilemma, as weaker nations began to develop their own indigenous space programs and had technological diffusion from one of the hegemonies. Japan and India are two democracies that both sought support for their indigenous space programs from the west, particularly from the U.S. These two nations emerged from poverty …
Legitimizing The "Republican Monarch" A Reexamination Of French Foreign Policy In The Atlantic Alliance, 1958-1960, Drew Fedorka
Legitimizing The "Republican Monarch" A Reexamination Of French Foreign Policy In The Atlantic Alliance, 1958-1960, Drew Fedorka
HIM 1990-2015
This thesis focuses on the role foreign policy played in legitimizing the early French Fifth Republic from 1958 to 1960. I argue that President Charles de Gaulle employed foreign policy in the service of gaining public support for his new government and the new republic. Many historians have argued previously that his foreign policy of grandeur, as it came to be called, was used to recast international politics and France's role in them. My work diverges from these previous interpretations by arguing that Gaullist foreign policy served, in many instances, overarching domestic goals, not French international interests. I see foreign …

Turning Away From Your Slavic Brother: The Effects Of Identity On Relations Between Russia And Belarus, Matt Matejka
Turning Away From Your Slavic Brother: The Effects Of Identity On Relations Between Russia And Belarus, Matt Matejka
Electronic Theses and Dissertations
On September 24, 2011, it was announced that Putin would run for president once again in 2012. The reaction in the West was that ―the more things change, the more they stay the same.‖ The Western conception of the post-Cold War Russia is often one of remarkable consistency since the turn of the century. This Western narrative focuses on an autocratic Putin reigning over his resurgent and confrontational Russia. Does this narrative tell the story of Russia today, or does it instead obscure it? To answer this I have elected to analyze Russian identity and how it relates to Russia‘s …
Infrared Detectors Based On Semiconductor P-N Junction Of Pbse, Vladimir Kasiyan, Zinovi Dashevsky, Casey Minna Schwarz, M. Shatkhin, Elena Flitsiyan, Leonid Chernyak, Dmitry Khokhlov
Infrared Detectors Based On Semiconductor P-N Junction Of Pbse, Vladimir Kasiyan, Zinovi Dashevsky, Casey Minna Schwarz, M. Shatkhin, Elena Flitsiyan, Leonid Chernyak, Dmitry Khokhlov
Faculty Bibliography 2010s
P-n junctions based on physical vapor deposition of thin PbSe films and conductivity type inversion from n- to p-type are developed and characterized over a wide range of temperatures and bias voltages. Photosensitivity and diode characteristics in the thin film PbSe diode structures were found at temperatures up to 300 K. The values of the measured and estimated parameters of these structures demonstrate their high photodetector performance and the potential for development of IR detectors with optimal sensitivity at the highest possible operating temperature.
Spectral Analysis Of Certain Schrodinger Operators, Mourad E.H. Ismail, Erik Koelink
Spectral Analysis Of Certain Schrodinger Operators, Mourad E.H. Ismail, Erik Koelink
Faculty Bibliography 2010s
The J-matrix method is extended to difference and q-difference operators and is applied to several explicit differential, difference, q-difference and second order Askey-Wilson type operators. The spectrum and the spectral measures are discussed in each case and the corresponding eigenfunction expansion is written down explicitly in most cases. In some cases we encounter new orthogonal polynomials with explicit three term recurrence relations where nothing is known about their explicit representations or orthogonality measures. Each model we analyze is a discrete quantum mechanical model in the sense of Odake and Sasaki [J. Phys. A: Math. Theor. 44 (2011), 353001, 47 pages].
Orthogonal Basic Hypergeometric Laurent Polynomials, Mourad E.H. Ismail
Orthogonal Basic Hypergeometric Laurent Polynomials, Mourad E.H. Ismail
Faculty Bibliography 2010s
The Askey-Wilson polynomials are orthogonal polynomials in x = cos theta, which are given as a terminating (4)phi(3) basic hypergeometric series. The non-symmetric Askey-Wilson polynomials are Laurent polynomials in z = e(i theta), which are given as a sum of two terminating (4)phi(3)'s. They satisfy a biorthogonality relation. In this paper new orthogonality relations for single (4)phi(3)'s which are Laurent polynomials in z are given, which imply the non-symmetric Askey-Wilson biorthogonality. These results include discrete orthogonality relations. They can be considered as a classical analytic study of the results for non-symmetric Askey-Wilson polynomials which were previously obtained by affine Hecke …

Maritime Pirates And Foreign Terrorist Organizations: Complicit Against The United States And Nato?, William Lusk
Maritime Pirates And Foreign Terrorist Organizations: Complicit Against The United States And Nato?, William Lusk
Electronic Theses and Dissertations
Maritime piracy, a phenomenon which has plagued free maritime trade for thousands of years, has entered a new age of sophistication and global reverberation. These acts of illegal criminal activity in the late twentieth and early twenty-first centuries yield a significant profit margin for the perpetrators while creating considerable cost for ransom payments, security measures, capital, and human life. The classification of maritime pirates, as either criminals hoping to gain financial income or terrorists hoping to usher in political change, is warranted and compelling. If maritime pirates conduct their operations to institute political change, it is possible that flags of …
An Impact Evaluation Of U.S. Arms Export Controls On The U.S. Defense Industrial Base An Interrupted Time-Series Analysis, Aaron Condron
An Impact Evaluation Of U.S. Arms Export Controls On The U.S. Defense Industrial Base An Interrupted Time-Series Analysis, Aaron Condron
HIM 1990-2015
The United States Defense Industrial Base (USDIB) is an essential industry to both the economic prosperity of the US and its strategic control over many advanced military systems and technologies. The USDIB, which encompasses the industries of aerospace and defense, is a volatile industry - prone to many internal and external factors that cause demand to ebb and flow widely year over year. Among the factors that influence the volume of systems the USDIB delivers to its international customers are the arms export controls of the US. These controls impose a divergence from the historical US foreign policy of furthering …
Integration Of Communication Constraints Into Physiocomimetic Swarms Via Placement Of Location Based Virtual Particles, Joshua J. Haley
Integration Of Communication Constraints Into Physiocomimetic Swarms Via Placement Of Location Based Virtual Particles, Joshua J. Haley
HIM 1990-2015
This thesis describes a change to the Physiocomimetics Robotic Swarm Control framework that implements communication constraints into swarm behavior. These constraints are necessary to successfully implement theoretical applications in the real world. We describe the basic background of swarm robotics, the Physiocomimetics framework and methods that have attempted to implement communications constraints into robotic swarms. The Framework is changed by the inclusion of different virtual particles at a global and local scale that only cause a force on swarm elements if those elements are disconnected from a swarm network. The global particles introduced are a point of known connectivity and …

Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler
Effects Of 3d Stereoscopy, Visuo-Spatial Working Memory, And Perceptions Of Simulation Experience On The Memorization Of Confusable Objects, Joseph R. Keebler
Electronic Theses and Dissertations
This dissertation investigated the impact of active stereoscopic 3-dimensional (3D) imagery equipment and individual differences in visuo-spatial working memory (VSWM) capacity on retention of a set of similar, novel objects (i.e., armored military vehicles). Seventy-one participants were assessed on their visuo-spatial working memory using the Visual Patterns Test (Della Sala, Gray, Baddeley, & Wilson, 1997). They were then assigned to one of four different conditions (3D high VSWM, 3D low VSWM, 2D high VSWM, 2D low VSWM) based upon their visuo-spatial working memory. Participants were then trained to identify military vehicles using a simulation that presented the training stimuli in …
Effect Of Neutron Radiation On The Mechanical Properties Of B4c, Zichao Xia
Effect Of Neutron Radiation On The Mechanical Properties Of B4c, Zichao Xia
Electronic Theses and Dissertations
B4C is an important engineering ceramic used in a number of different applications. One of the promising applications of B4C is in the nuclear industry. B4C has a high neutron absorption cross-section (600 barns) and that is why it can absorb neutrons without forming long lived radio nuclides. As a result, B4C is extensively used as control rods, shielding material and as neutron detectors in nuclear reactors. During the reactor’s operation, the B4C undergoes severe neutron radiation and defects, such as vacancies and helium bubbles, are generated in the structure. These defects are responsible for the degradation of mechanical performance …

Divided Government And Congressional Foreign Policy A Case Study Of The Post-World War Ii Era In American Government, David Eric Feinman
Electronic Theses and Dissertations
The purpose of this research is to analyze the relationship between the executive and legislative branches of American federal government, during periods within which these two branches are led by different political parties, to discover whether the legislative branch attempts to independently legislate and enact foreign policy by using “the power of the purse” to either appropriate in support of or refuse to appropriate in opposition to military engagement abroad. The methodology for this research includes the analysis and comparison of certain variables, including public opinion, budgetary constraints, and the relative majority of the party that holds power in one …
The Israeli Military's Key Relationship To Hezbollah Terror, Mazen Kurdy
The Israeli Military's Key Relationship To Hezbollah Terror, Mazen Kurdy
Electronic Theses and Dissertations
This research examines the establishment and expansion of Hezbollah. It uses a policy perspective in explaining the growth of this organization. Moreover, it focuses on Israel’s disproportionate use of force in Lebanon as a major cause behind the very existence of Hezbollah. The analysis of Israeli policy will be done by examining three separate conflicts as case studies. These events are: the 1982 (Peace for Galilee) invasion of Lebanon that helped to create Hezbollah, the 1996 (Operation Grapes of Wrath) Hezbollah-Israeli conflict which served to bolster Hezbollah in Lebanon, and finally the 2006 Hezbollah-Israeli war which solidified Hezbollah as a …
Cultural Differences In Forgiveness Fatalism, Trust Violations, And Trust Repair Efforts In Interpersonal Collaboration, Jessica L. Wildman
Cultural Differences In Forgiveness Fatalism, Trust Violations, And Trust Repair Efforts In Interpersonal Collaboration, Jessica L. Wildman
Electronic Theses and Dissertations
Mistakes and betrayals can cause developing interpersonal trust between parties to be broken, and damaged trust can have serious negative impacts on relationships, such as withdrawal from group interaction or the enactment of revenge. Research has suggested that the use of apologies helps to repair damaged trust. However, this research is almost exclusively based in westernized populations and has not begun to explore any cross-cultural differences. Therefore, the primary goal of this comparative cross-national laboratory study was to examine if, and how, the effectiveness of trust repair efforts differs across cultures. The effectiveness of three manipulated trust repair strategies (no …

Marker Free Transgenic Plants: Engineering The Chloroplast Genome Without The Use Of Antibiotic Selection, Henry Daniell
Marker Free Transgenic Plants: Engineering The Chloroplast Genome Without The Use Of Antibiotic Selection, Henry Daniell
UCF Patents
The present invention provides for a method to circumvent the problem of using antibiotic resistant selectable markers. In particular, target plants are transformed using a plastid vector which contains heterologous DNA sequences coding for a phytotoxin detoxifying enzyme or protein. The selection process involves converting a antibiotic-free phytotoxic agent by the expressed phytotoxin detoxifying enzyme or protein to yield a nontoxic compound. The invention provides for various methods to use antibiotic-free selection in chloroplast transformation.

Death And Disengagement: A Critical Analysis Of The International Community's Intervention Effort In Darfur, Victor Hodges
Electronic Theses and Dissertations
This thesis seeks to analyze the international community's conflict management capabilities through its response to the Darfur crisis. Primarily, it aims to show through the lens of the Darfur crisis, which is widely accepted as the first genocide of the twenty-first century, that the international community has yet to develop a framework to collectively intervene in and resolve crimes against humanity. Additionally, this thesis will show the international community's recognition of their shortcomings through the gradual transformation of policies undertaken by several of its leading entities in response to the crisis. The research will pinpoint several major factors behind the …

Faculty Bibliography 2010s
A novel capability was designed, implemented, and tested for in situ neutron diffraction measurements during loading at cryogenic temperatures on the spectrometer for materials research at temperature and stress at Los Alamos National Laboratory. This capability allowed for the application of dynamic compressive forces of up to 250 kN on standard samples controlled at temperatures between 300 and 90 K. The approach comprised of cooling thermally isolated compression platens that in turn conductively cooled the sample in an aluminum vacuum chamber which was nominally transparent to the incident and diffracted neutrons. The cooling/heat rate and final temperature were controlled by …
Decoherence By Electromagnetic Fluctuations In Double-Quantum-Dot Charge Qubits, Diego C. B. Valente, Eduardo R. Mucciolo, F. K. Wilhelm
Decoherence By Electromagnetic Fluctuations In Double-Quantum-Dot Charge Qubits, Diego C. B. Valente, Eduardo R. Mucciolo, F. K. Wilhelm
Faculty Bibliography 2010s
We discuss decoherence due to electromagnetic fluctuations in charge qubits formed by two lateral quantum dots. We use effective circuit model to evaluate correlations of voltage fluctuations in the qubit setup. These correlations allows us to estimate energy (T(1)) and phase (T(2)) relaxation times of the qubit system. Our theoretical estimate of the quality factor due to dephasing by electromagnetic fluctuations yields values much higher than those found in recent experiments, indicating that other sources of decoherence play a dominant role.
Low Temperature Deformation Of The R-Phase In A Nitife Shape Memory Alloy, V. B. Krishnan, S. B. Shmalo, C. R. Rathod, M. A. M. Bourke, R. Vaidyanathan
Low Temperature Deformation Of The R-Phase In A Nitife Shape Memory Alloy, V. B. Krishnan, S. B. Shmalo, C. R. Rathod, M. A. M. Bourke, R. Vaidyanathan
Faculty Bibliography 2010s
Deformation in the P3 phase (R-phase) of NiTiFe was investigated by in situ neutron diffraction during compressive loading at cryogenic temperatures. At 216 K, upon loading the R-phase detwinned and subsequently underwent a reversible stress-induced transformation to the B19' phase (martensite). At 92 K on the other hand, detwinning was suppressed and the stress-induced martensite formed did not transform back upon unloading. The experiments also directly observed a hitherto theoretically predicted B33 phase. Rietveld refinement of the neutron diffraction spectra were used to determine lattice parameters of the B33 and R-phases. Plane-specific elastic moduli were also determined for the R-phase.

Comparison Of Traditional Standard Drainfield With Innovative B&G Treatment Bed For Nutrient Removal From Septic Tank Wastewater, Fahim Hossain
Electronic Theses and Dissertations
Nowadays people are more alert about conservation of water and water scarcity. The amount of usable water is decreasing due to unavailability of pure water for day to day use. Both surface and groundwater is contaminated by untreated wastewater discharged from improper onsite wastewater treatment system, nutrient laden agricultural runoff and increasing use of fertilizer in fields. This elevated nutrient level is increasing the maintenance and operation cost of water treatment plant. So it is an important task to remove those nutrients from wastewater and other water bodies by applying environmental friendly process. In the USA, about 25% homes are …
