Towards Development Of A Remote Charting System For Connected Healthcare, Alex Bodurka

Masters Theses

Health Care Providers play a crucial role in a patients well-being. While their primary role is to treat the patient, it is also vital to ensure that they can spend adequate time with the patient to create a unique treatment plan and build a personal relationship with their patients to help them feel comfortable during their treatment. Health Care Providers are frequently required to manually record patient data to track their healthcare progress during their hospital stay. However, with hospitals continuously trying to optimize their workflows, this crucial one-on-one time with the patient is often not practical.

As a solution, …

Organocatalyzed Synthesis Of Epoxides From Chalcones Utilizing Amino Acids, Sabrina N. Kegeler

Masters Theses

The epoxide functional group is important throughout the chemical and pharmaceutical industries, as well as in nature. In the chemical industry, epoxides are present in resins and fragrances. In the pharmaceutical industry, epoxide-containing compounds are used as intermediates in the manufacturing of drugs. In nature, many natural products contain epoxide groups and are used for medicinal purposes, and for models to create synthetic molecules.

One approach to epoxide synthesis involves the use of an alkene precursor, a base, and an oxidizing agent. This is where my investigations began. The first step was to optimize the epoxidation reaction, examining substrate scope, …

Gpu-Accelerated Influenza Simulations For Operational Modeling, Peter Holvenstot

Masters Theses

Simulations of influenza spread are useful for decision-making during public-health emergencies. Policy-makers use models to predict disease spread and estimate the effects of various intervention strategies. Effective modeling of targeted intervention strategies requires accurate modeling of individual-level behavior and transmission. However, this greatly increases the computational costs of these agent-based models. In addition, if the models are used as an outbreak progresses, some operational decisions must occur rapidly in order to contain the spread of the disease.

Graphics Processing Units (GPUs) are a type of specialized processor used to drive graphical displays. Many recent devices also allow users to write …

Study Of The Insulin Mimetic Sodium Orthovanadate In Glucosamine Induced Insulin Resistnace In Primary Rat Hepatocytes, Kalan Mcpherson

Masters Theses

Insulin resistance and type II diabetes is a disease state characterized by a lack of sensitivity of insulin to provoke a proper response in insulin sensitive tissues. Currently, we utilize glucosamine to increase flux through the Hexosamine Biosynthetic Pathway (HBP) to induce an insulin resistance like state in primary rat hepatocytes. We tested the effectiveness of the insulin mimetic sodium orthovanadate to determine if it could elicit an insulin-like response under these conditions. Mixed results were obtained on the effectiveness of vanadate as an insulin mimetic in this insulin resistant model.

Privacy And Security Issues In Iot Healthcare Applications For The Disabled Users A Survey, Wassnaa Al-Mawee

Masters Theses

Aging of the population resulted in new challenges for the society and healthcare systems. Ambient Assisted Living (AAL) that depends on Internet of Things (IoT) provides assistance to the disabled people and supports their vital daily life activities. Affordability of and accessibility to AAL and the usage of IoT starts revolutionizing healthcare services. This Thesis is a survey of the privacy and security issues in IoT healthcare applications for the disabled users. Introduction includes definitions of privacy and security terms, and discusses their relationship. Then, it presents an overview of the IoT, including its architecture and components. Next, the Thesis …

Signal Processing With Neural Networks, Pero Smrzlic

Masters Theses

In this study, we introduce the Adaptive Back Propagation (ABP) learning algorithm, computationally superior to the standard Back Propagation. The ABP is based on the new activation function, with its corresponding adaptive learning parameter. By using the combination of computer simulations and analysis in the domain of activation function, the Method of One Hidden layer was developed for the effective utilization of units in one-hidden layer networks. A parallel version of the ABP was designed and implemented on a nCUBE-2 supercomputer with 128 processors.

The simulation results suggested a strong correlation between frequency of signals and the role of hidden …

Time Delay Neural Networks And Speech Recognition: Context Independence Of Stops In Different Vowel Environments, Gregory Andrew Makowski

Masters Theses

A series of speech recognition experiments was conducted to investigate time-dynamic speech recognition of stop consonants invariant of vowel environment using data from six talkers. The speech preprocessing was based on previous studies investigating acoustic characteristics which correlate to the place of articulation (Blumstein and Stevens 1979). The place of articulation features were statistically abstracted using four moments and the energy level of the speech sample.

Both statistical and neural network pattern recognition methods were used. Statistical methods included linear and quadratic discriminant functions, maximum likelihood estimator (MLE) and K-nearest neighbors (KNN). The neural network approach used was Time Delay …

The Survival Of Mesophilic And Thermophilic Bacteria Subjected To Uv Irradiation, Sajida A. Shaikh

Masters Theses

Survival curves were determined for the mesophile, Bacillus licheniformis and the thermophile, Bacillus stearothermophilus after subjecting the cells to ultraviolet irradiation. Cells were grown at 37°C for the mesophile and at 55°C for the thermophile.

At low UV exposure times, the thermophile was more resistant to UV irradiation (had a better survival rate) than was the case for the mesophile. At higher exposure times, the situation was reversed, the mesophile having a greater survival rate than the thermophile.

The effect of changes in the temperature during irradiation was also determined. Thermophiles were greatly affected by changes in temperature while the …
