Ballistocardiography : physically-based modeling to bridge physiology and technology
(University of Missouri--Columbia, 2020)
The ballistocardiogram (BCG) captures the motion of the center of mass (CoM) of the human body resulting from the blood motion within the circulatory system. The BCG signal reflects the status of the cardiovascular system ...
Modeling and simulation of a segmented thermoelectric generator
(University of Missouri--Columbia, 2017)
the TEG geometry. It was found that the original model can be further optimized. After optimization, the output power increases from 188.2mW to 354.7mW, 703.13mW, and 212.85mW, respectively. Conversion efficiency increases from 1.66 percent to 2.08 percent...
Towards real-time object detection on edge with deep neural networks
(University of Missouri--Columbia, 2018)
Despite being a core topic for more than several decades, object detection is still receiving increasing attentions due to its irreplaceable importance in a wide variety of applications. Abundant object detectors based on ...
Bayesian approach for the spectrum sensing mimo-cognitive radio network with presence of the uncertainty
(University of Missouri--Columbia, 2021)
A cognitive radio technique has the ability to learn. This system not only can observe the surrounding environment, adapt to environmental conditions, but also efficiently use the radio spectrum. This technique allows the ...
Temporal decision making using unsupervised learning
(University of Missouri--Columbia, 2021)
clustering to build an adaptive system for analyzing streaming multi-dimensional activity feature vectors. For this reason, the possibilistic C-Means (PCM) and Automatic Merging Possibilistic Clustering Method (AMPCM) are combined together to cluster...
RF sensing and processing methods for noninvasive health monitoring
(University of Missouri--Columbia, 2021)
Vulnerable populations include groups of people with a higher risk of poor health as a result of the limitations due to illness or disability. The health issues of vulnerable populations include three categories: physical, ...
Sub-optimal and robust downlink beamforming in wireless networks with imperfect channel state information
(University of Missouri--Columbia, 2021)
The rapid growth in internet applications such as video streaming enforce the researcher to explore a new wireless technique to ensure high signal to interference noise ratio (SINR) at the end users, leading to high quality ...
Explainable pattern modelling and summarization in sensor equipped smart homes of elderly
(University of Missouri--Columbia, 2020)
In the next several decades, the proportion of the elderly population is expected to increase significantly. This has led to various efforts to help live them independently for longer periods of time. Smart homes equipped ...
Deep learning with very few and no labels
(University of Missouri--Columbia, 2021)
Deep neural networks have achieved remarkable performance in many computer vision applications such as image classification, object detection, instance segmentation, image retrieval, and person re-identification. However, ...
Biophysical modeling to reverse engineer two mammalian neural circuits lower urinar Y tract and hippocampus
(University of Missouri--Columbia, 2020)
Computational neuroscience provides tools to abstract and generalize principles of neuronal function using mathematics and computers. This dissertation reports biophysical modeling approaches to facilitate reverse engineering ...
Multicriteria pathfinding in uncertain simulated environments
(University of Missouri--Columbia, 2018)
Multicriteria decision-making problems arise in all aspects of daily life and form the basis upon which high-level models of thought and behavior are built. These problems present various alternatives to a decision-maker, ...
Advanced nanodielectric material development and scaling for use in compact ultra-high voltage capacitor prototypes
(University of Missouri--Columbia, 2019)
The dielectric material employed in this effort is a proprietary nanocomposite material, MU100. The material was initially developed to shrink high frequency, high voltage, dielectric loaded antennas; however, due to its ...
Unpaved road detection using optimized log Gabor filter banks
(University of Missouri--Columbia, 2021)
The revised unpaved road detection system (RURD) is a novel method for detecting unpaved roads in an arid environment from color imagery collected by a forward-looking camera mounted on a moving platform. The objective is ...
Investigation of nanoenergetic combustion study of aluminum nanoparticles systems on plasmonic grating platform
(University of Missouri--Columbia, 2022)
With renewed interest in energetic materials like aluminum, many fundamental issues concerning the ignition and combustion characteristics at nanoscales remain to be clarified. Aluminum nanoparticles (Al NP) are widely ...
Non-invasive monitoring of vital signs using recliner chair and respiratory pattern analysis
(University of Missouri--Columbia, 2018)
In-home monitoring has the potential to help track health changes for older adults with chronic health conditions, thereby making early treatment possible when exacerbations arise. A recliner chair is often used by older ...
Data-driven methods for analyzing ballistocardiograms in longitudinal cardiovascular monitoring
(University of Missouri--Columbia, 2019)
Cardiovascular disease (CVD) is the leading cause of death in the US; about 48% of American adults have one or more types of CVD. The importance of continuous monitoring of the older population, for early detection of ...
