Assessment Of Adaptability Of A Supply Chain Trading Agent’S Strategy: Evolutionary Game Theory Approach, Yoon Sang Lee, Riyaz T. Sikora Jan 2019

Assessment Of Adaptability Of A Supply Chain Trading Agent’S Strategy: Evolutionary Game Theory Approach, Yoon Sang Lee, Riyaz T. Sikora

Journal of International Technology and Information Management

With the increase in the complexity of supply chain management, the use of intelligent agents for automated trading has gained popularity (Collins, Arunachalam, B, et al. 2006). The performance of supply-chain agents depends on not just the market environment (supply and demand patterns) but also on what types of other agents they are competing with. For designers of such agents it is important to ascertain that their agents are robust and can adapt to changing market and competitive environments. However, to date there has not been any work done that assesses the adaptability of a trading agent’s strategy in the …

Measurements Of The Primary Bjerknes Force In A Cavitating Ultrasonic Field, Mason Smith Jan 2019

Measurements Of The Primary Bjerknes Force In A Cavitating Ultrasonic Field, Mason Smith

Honors Theses

Cavitation is the result when there are rapid changes in pressure in a liquid. These vapor-filled cavities can occur when ultrasound propagates through water at sufficient power. The volumes of these cavities can pulsate and can even couple with the radiation pressure from the ultrasound. The result is a translational force on the bubbles. This translational force on the bubble is called the primary Bjerknes force. The secondary Bjerknes force is the result of two pulsating cavities, but this force is ignored since the buoyant force and the primary Bjerknes force are the dominant forces. Immediately before a bubble begins …

Renewables & Refugees: A Solution For Jordan, Lauren Burns Jan 2019

Renewables & Refugees: A Solution For Jordan, Lauren Burns

Honors Theses

As the Hashemite Kingdom of Jordan continues to host the third largest Syrian refugee population in the world, the state’s infrastructure and its people are taking a toll. Before the war in Syria began, Jordan was already suffering from a weak economy, resource scarcity, and an enormous population boom. Since accepting nearly 2.5 million refugees, these issues have compounded year after year—nearly reaching a breaking point. I propose an unconventional solution to some aspects of the refugee crisis: renewable energy. Renewables are cheaper than fossil fuels, consume less water in electricity generation, emit fewer greenhouse gases, and promote job creation …

Faculty & Staff Scholarship

Applications of wavelet analysis in ultra-thin film transient reflectivity (TR) measurements have been investigated. Advantages of utilizing different localized wavelet bases, in position and time, have been addressed on the residual TR signals. Morse wavelets have been used to obtain information from the abrupt oscillatory modes in the signal, which are not distinguishable with conventional methods such as Fourier transforms. These abrupt oscillatory modes are caused by the surface, interface, or any short-lived oscillatory modes which are suppressed in the TR signal in ultra-thin films. It is demonstrated that by choosing different Morse wavelets, information regarding different oscillatory modes in …

Faculty & Staff Scholarship

Methanol soluble and stable guanosine octamers were successfully achieved via H-bond self-assembly. Through structural conformational design, we developed a new class of guanosine derivatives with modification on guanine (8-aryl) and ribose (20 ,30 -isopropylidene). This unique design led to the formation of the first discrete G8-octamer with its structure characterized by single crystal X-ray diffraction, MS and NMR spectroscopy. The G8-octamer showed unique cation recognition properties, including the formation of a stable Rb+ templated G-quadruplex. Based on this observation, further modification on the 8-aryl moiety was performed to incorporate a cross-layer H-bond or covalent linkage. Similar G-octamers were obtained in …

Unexpected Outcomes During The Attempted Iodination Of Biphenol, Henry Nguyen Jan 2019

Unexpected Outcomes During The Attempted Iodination Of Biphenol, Henry Nguyen

Honors Theses

The goal of this research was to create a new procedure to iodinate 4,4- biphenol using a ball miller. Iodination of 4,4-biphenol was first attempted in solution using electrophilic aromatic substitution. Several attempts were made to iodinate 4,4-biphenol, but the general insolubility of crude products inhibited progress. Interestingly, NMR analysis of the aqueous ammonia product suggested that 4,4-biphenol dimerized or polymerized with itself to make an ether. The exact mechanism by which the ether dimer was created is unknown, but the reaction may have occurred using a radical mechanism. Though the original goal of the project is left unmet, a …

Applying Markov Processes To Model Disability In Relapsing Multiple Sclerosis Patients, Anastasia Hartzes Jan 2019

Applying Markov Processes To Model Disability In Relapsing Multiple Sclerosis Patients, Anastasia Hartzes

All ETDs from UAB

Modeling disability in multiple sclerosis (MS) is challenging due to its complexity and non-linearity, with utilized methodology having many limitations. Lack of a suitable biomarker has led to relying on statistical models to understand disease progression. Markov methodology has been limitedly applied to the clinically-assessed Expanded Disability Status Score (EDSS), but not to patient-reported Patient Determined Disease Steps (PDDS); both measure disease progression and disability, and neither have been analyzed using the Test of Lumpability (TOL). It is common practice to aggregate these scores for computational or inferential convenience; in the case of Markov Chains (MC), combining states is referred …

A Study Of Approximation Error In Eulerian Hydrocodes, Parth Yogeshbhai Patel Jan 2019

A Study Of Approximation Error In Eulerian Hydrocodes, Parth Yogeshbhai Patel

All ETDs from UAB

In this study, we examine a number of approximations in the formulation of hydrocodes. These approximations were borne out of an original requirement for the code to run as fast as possible i.e. with accuracy being secondary to speed. Many of these approximations originated from the 1970’s when computers were slow and memory was at a premium. Although speed and memory are not as much of an issue today, these approximations are still used to formulate the hydrocodes. In this study, the effect of these approximations is examined systematically. The lumped mass approximation is a simplification to the consistent mass …

Quantifications Of Theranostic Polymer-Based Particles For Image-Guided Drug Delivery, Sithira Ratnayaka Jan 2019

Quantifications Of Theranostic Polymer-Based Particles For Image-Guided Drug Delivery, Sithira Ratnayaka

All ETDs from UAB

Modern medicine employs many drugs in its disease treatment methods. This is because they provide the best permanent solutions to complicated ailments. However the usefulness of these drugs is mitigated by several factors, namely that of specific release. Common drug delivery mechanisms lack the specificity needed to ensure that release is limited to the diseased area, which can lead to unnecessary side effects. By utilizing medical imaging, both drug delivery devices and physiology can be observed by physicians, which can greatly increase the specificity of drug delivery. Specifically, utilizing a very inert medical imaging modality, such as ultrasound, guarantees minimum …
