Lost circulation and problems related to drilling present a major challenge for the drilling industry. Each year, billions are spent to treat these problems. There is not a single solution to lost circulation because of the complexity and kind of formations susceptible to this issue. Lost circulation treatment data for the Shuaiba formation (induced fractured formation) were gathered from drilled wells in Southern Iraq (over 2000). Treatments have been grouped according to the volume of mud loss as complete, severe, and partial loss remedies. Detailed costs and probabilities calculations were conducted. The costs of three types of loss treatments (partial, …

Studies On Tornado-Structure Interactions And Guidance On Design Tornadic Wind Loading, Zhi Li Jan 2021

Studies On Tornado-Structure Interactions And Guidance On Design Tornadic Wind Loading, Zhi Li

Doctoral Dissertations

“Tornadoes are violent natural hazards that could caused significant property loss and fatalities. Statistical data indicates that most fatalities during tornado incidents were caused by the building failure under tornadoes. For example, in the 2011 Joplin Tornado, 161 people were killed, and 84 percent of the fatalities were related to the failure of buildings. In addition, most of the significant, tornado-induced property loss and fatalities are relevant to the tornadoes passing through the densely populated regions. Besides buildings, bridges were also severely damaged or destroyed by tornadoes in the United States. To reduce the tornado-induced loss, it is imperative to …

Adaptive Dynamic Programming Methods For Tracking Current Control Of Switched Reluctance Motor Drive, Hamad Alharkan Jan 2021

Adaptive Dynamic Programming Methods For Tracking Current Control Of Switched Reluctance Motor Drive, Hamad Alharkan

Doctoral Dissertations

“This research investigates the application of adaptive dynamic programming (ADP) methods for the current control of switched reluctance motors (SRM). Since the traditional current controllers have large current ripples that increase torque ripples and acoustic noise, optimal tracking controllers using reinforcement learning (RL) approaches are introduced as an alternative adaptive technique for SRM drives. The proposed optimal tracking controllers can minimize current ripples and cope with uncertainties within the inductance profile of the SRM. The work is composed of three papers. In the first paper, a novel Q-learning scheduling method for the current controller of a switched reluctance motor (SRM) …

Advanced Control Techniques For Modern Inertia Based Inverters, Sepehr Saadatman Jan 2021

Advanced Control Techniques For Modern Inertia Based Inverters, Sepehr Saadatman

Doctoral Dissertations

”In this research three artificial intelligent (AI)-based techniques are proposed to regulate the voltage and frequency of a grid-connected inverter. The increase in the penetration of renewable energy sources (RESs) into the power grid has led to the increase in the penetration of fast-responding inertia-less power converters. The increase in the penetration of these power electronics converters changes the nature of the conventional grid, in which the existing kinetic inertia in the rotating parts of the enormous generators plays a vital role. The concept of virtual inertia control scheme is proposed to make the behavior of grid connected inverters more …

Frequency-Selective Metasurface Integrated Uncooled Microbolometers, Mahmoud Almasri, Edward C. Kinzel Jan 2021

Frequency-Selective Metasurface Integrated Uncooled Microbolometers, Mahmoud Almasri, Edward C. Kinzel

Patents

A metasurface integrated microbolometer having a sensing layer (e.g., SixGeyOI-x-y ). The presence of the metasurface provides selectivity with respect to wavelength, polarization and angle-of-incidence. The presence of the metasurface into the microbolometer affects conversion of electromagnetic to thermal energy, thermal response, electrical integration of the micro bolometer, and the tradeoff between resistivity and temperature coefficient of resistance, thereby allowing the ability to obtain a sensing with high temperature coefficient of resistance with lower resistivity values than that of films without the metasurface. The presence of the metasurface removes the need for a Fabry-Perot cavity.

Endobariatric Procedures For Obesity: Clinical Indications And Available Options., Hemant Goyal, Jonathan Kopel, Abhilash Perisetti Md, Rupinder Mann, Aman Ali, Benjamin Tharian, Shreyas Saligram, Sumant Inamdar

Other Specialties

Obesity remains a growing public health epidemic that has increased healthcare costs and related comorbidities. Current treatment guidelines encourage a multidisciplinary approach starting from patient selection, interventions, and long-term follow-up to maintain weight loss. However, these conservative interventions are largely ineffective at reducing body weight due to low adherence to the treatment regimen. Recently, endoscopic bariatric therapies have become an attractive alternative to traditional invasive bariatric surgeries due to their improved efficacy, safety, and cost-effectiveness. Endoscopic bariatric therapies include intragastric balloon placement, endoscopic sleeve gastroplasty, gastric bypass revision, and aspiration therapy. These procedures fall into two separate categories depending on …

The Missing D In U.S. Foreign Relations Law, David H. Moore Jan 2021

The Missing D In U.S. Foreign Relations Law, David H. Moore

Faculty Scholarship

United States foreign relations law once subsisted on the outskirts of constitutional and international law. Now a recognized field of scholarship in its own right, foreign relations law addresses some of the most important questions of our time, such as whether the President may unilaterally conduct strikes against Iran or withdraw from the Paris Climate Agreement. For all its importance, however, U.S. foreign relations law has developed with blinders on. U.S. foreign policy embraces at least three Ds: defense, diplomacy, and development. Yet foreign relations law scholarship has approached the critical questions of the field almost exclusively through the lens …

Christian Dignity And The Overlapping Consensus, Frederick Mark Gedicks Jan 2021

Christian Dignity And The Overlapping Consensus, Frederick Mark Gedicks

Faculty Scholarship

This Article rejects arguments by Christian leaders, scholars, and others who lament the secularization of the West and urge Christian dignity as the foundation of universal human rights. It argues instead that only a secular conception of dignity free of Christian metaphysics can create an overlapping consensus in support of human rights.

Part I describes the roots of Christian dignity in medieval theology and status. Part II briefly recounts how the Renaissance and Enlightenment re-centered the end of dignity from knowing God to knowing oneself, while the Reformation’s extension of original sin to the intellect left Catholicism as the primary …

The Russian Coordinating Conjunctions И And А: Their Meaning, Function, And Pedagogy, Mark J. Elson Jan 2021

The Russian Coordinating Conjunctions И And А: Their Meaning, Function, And Pedagogy, Mark J. Elson

Russian Language Journal

This paper is concerned with the systemic status of the coordinating conjunctions и and а in Contemporary Standard Russian. Most previous treatments of и and а have, without comment, viewed them as minimal syntactic units (i.e., words) defined, for systemic purposes, functionally—as equating or likening in the case of и but contrasting or opposing in that of а. However, these treatments, whether intentionally or unwittingly, have left unattended the possibility that и and а, although syntactic units, are more properly defined grammatically (i.e., are systemically characterized by an invariant grammatical meaning of which their functions are derivative).1 At …

From Error Annotation To Quantitative Analysis: Patterns In Russian Language Learning, Irina Kor Chahine, Ekaterina Uetova Jan 2021

From Error Annotation To Quantitative Analysis: Patterns In Russian Language Learning, Irina Kor Chahine, Ekaterina Uetova

Russian Language Journal

Although learner corpus research has been progressively growing into an independent branch of corpus linguistics, the learner corpus cannot yet fully benefit from corpus analysis methods. This is due to several technical obstacles involving data collection, error annotation, and finally, data processing. When it comes to data collection, compared to corpus linguistics, learner corpus is biased because some of the learner corpora are still collected manually: Optical character recognition (OCR) is not yet sophisticated enough to transform a student’s handwritten copy to a digitized text. This fact significantly slows the collection of learner corpora. Furthermore, typed students’ texts present another …

Access to information is the purpose of the Internet. Ask anyone born after the dawn of the information age; they will tell you that cyberspace is the place to go if one wants to know stuff. On the other hand, many of the people who put stuff on the Internet or on systems connected to the Internet will tell you that, without legal rights to control or block access, people will not have incentives to put on the Internet stuff that is worth knowing. In this tension between access and control, property is generally assumed to be on the side …

Racial Disparities In Liver Disease In The Us: Addressing The High Prevalence Of Hepatitis B Infection In The Apia Community, Lindsey L. Trinh, Lindsey Trinh Jan 2021

Racial Disparities In Liver Disease In The Us: Addressing The High Prevalence Of Hepatitis B Infection In The Apia Community, Lindsey L. Trinh, Lindsey Trinh

Scripps Senior Theses

Chronic liver disease and hepatocellular carcinoma are some of the leading causes of death in the United States, resulting in a number of annual deaths that has only increased over the past several decades. A vast proportion of these liver-related deaths is due to chronic hepatitis B infection, which currently affects approximately 1.2 million people in the US. However, the hepatitis B virus does not affect every racial group in the United States equally: Asian Americans experience a disproportionately high prevalence of HBV infection. In fact, even though the APIA community comprises only 4% of the US population, they account …
