Photo-Production Of Eta Mesons, Mahmoud Mohamed Kamel
Photo-Production Of Eta Mesons, Mahmoud Mohamed Kamel
FIU Electronic Theses and Dissertations
In this work we present the GlueX experiment extensive high statistics measurements of the η meson photo-production differential cross sections at beam energies between 3 GeV and 11.6 GeV. We compared the low energy (2.9 GeV< Eγ < 5.9 GeV) differential cross section (dσ/dΩ) results to previous experimental results from the Continuous Electron Beam Accelerator Facility (CEBAF) Large Acceptance Spectrometer (CLAS) collaboration. These (dσ/dΩ) results are also compared to the theoretical isobar model EtaMAID2018 by Tiator et. al., and the Regge model by Nys et. al. The differential cross section dσ/dt is also presented and compared to the previous experimental results, and to the above models, in addition to a model by J. M. Laget. The high energy (6.2 GeV< Eγ < 11.6 GeV) cross section results (dσ/dΩ, and dσ/dt) are compared to the isobar model EtaMAID2018. These results will provide new constraints on η photo-production mechanisms and high energy t- channel processes.
System Support Of Concurrent Database Query Processing On A Gpu, Hao Li
System Support Of Concurrent Database Query Processing On A Gpu, Hao Li
USF Tampa Graduate Theses and Dissertations
The unrivaled computing capabilities of modern GPUs meet the demand of processing massive amounts of data seen in many application domains. While traditional HPC systems support applications as standalone entities that occupy the entire GPU, we propose a GPU-based DBMS (G-DBMS) that can run multiple tasks concurrently. To that end, system-level management mechanisms like resource allocation and buffer manager are needed to build such a concurrent database query processing system and fully unleash the GPUs’ computing power. However, CUDA does not provide enough OS-level functionalities to support it. Thus our research is focusing on implementing the optimization of resource allocation …
Climate Change And Sustainable Development Within The Tourism Sector Of Small Island Developing States: A Case Study For The Bahamas, Arsum Pathak
USF Tampa Graduate Theses and Dissertations
The research literature suggests Small Island Developing States (SIDS) are vulnerable to climate change. Tourism in SIDS is sensitive to climate variations and dependence of the sector on natural resources (beaches, coral reefs) adds to their vulnerability. The purpose of this study is to assess climate impacts and adaptation within the tourism sector of a SIDS – The Bahamas that relies on tourism and faces climate vulnerabilities, as do other SIDS. Given the importance of tourism to their sustainable development by supporting economic growth and employment, this study identifies timely risks and adaptation planning for a tourism-based SIDS economy in …

Development Of Next-Generation, Fast, Accurate, Transferable, And Polarizable Force-Fields For Heterogenous Material Simulations, Adam E. Hogan
USF Tampa Graduate Theses and Dissertations
Theoretical modeling is extremely useful in guiding to experiment; however quantitatively accurate modeling of energy-relevant small molecule sorption at the heterogeneous interfaces present in metal-organic materials (MOMs) is currently challenging. MOMs are an emerging class of materials consisting of inorganic clusters and organic linkers that offer great potential in the areas of gas storage, gas separation, and catalysis due to the possibility of large surface areas, complex heterogeneous surfaces, and rational designability. Efficient chemical separations involving these materials could reduce the US’s total energy consumption by approximately 10 to 15%. In this dissertation, the parameterization of small molecules and metal …

Conversion From Metal Oxide To Mof Thin Films As A Platform Of Chemical Sensing, Meng Chen
USF Tampa Graduate Theses and Dissertations
Chemical sensor is working as a widely used device which can be applied to the detection of specific chemicals that are existing in the environment especially in gas phase. The detection of combustible and toxic chemicals can be extremely important in the field of both industrial and civil activities. The chemical sensor is commonly operating by utilizing a chemical or physical interaction between the specific chemical compound and the sensing functional unit, to obtain an electronic signal caused by the property change and realize the chemical detection. Traditional chemical gas sensors such as catalytic gas sensor, thermal conductivity gas sensor, …
Countermeasures Against Various Network Attacks Using Machine Learning Methods, Yi Li
Countermeasures Against Various Network Attacks Using Machine Learning Methods, Yi Li
USF Tampa Graduate Theses and Dissertations
With the rapid development of a computer network, our lives are already inseparable from it. Wireless Fidelity (Wi-Fi) is in use everywhere; more and more devices are connected to the Internet, and many companies and individuals tend to store their data and information online. Furthermore, it is now very convenient to communicate with each other through email and text messages. However, widespread networks also provide more attack surfaces for attackers. There are a variety of network attacks aimed at information theft. To better defend against those network attacks, one needs to have a broad knowledge of existing attacks. In this …

The Northern high latitudes are warming twice as fast as the global average, and permafrost has become vulnerable to thaw. Changes to the environment during thaw leads to shifts in microbial communities and their associated functions, such as greenhouse gas emissions. Understanding the ecological processes that structure the identity and abundance (i.e., assembly) of pre- and post-thaw communities may improve predictions of the functional outcomes of permafrost thaw. We characterized microbial community assembly during permafrost thaw using in situ observations and a laboratory incubation of soils from the Storflaket Mire in Abisko, Sweden, where permafrost thaw has occurred over the …

An Analysis Of Preservice Elementary Teachers’ Professional Noticing Skills In A Mathematics Education Setting, Liza Bondurant, Lisa Poling, Diana Moss
Journal of Practitioner Research
Prospective elementary mathematics teachers (PTs) were asked to analyze 28 videos of cognitive interviews. The purpose of this study was to determine if experiences analyzing videos would lead to improvements in PTs’ professional noticing skills. Using a coding schema that reflected three levels of understanding (periphery, transitional, and accomplished), a frequency table was constructed that allowed PTs’ use and understanding of a noticing framework to be analyzed. Findings indicate that experiences analyzing videos leads to improvements in PTs’ professional noticing skills.
