Clustering in relational data and ontologies
(University of Missouri--Columbia, 2010)
This dissertation studies the problem of clustering objects represented by relational data. This is a pertinent problem as many real-world data sets can only be represented by relational data for which object-based clustering algorithms...
Thermal management in GaAs/AlGaAs laser diode structures
(University of Missouri--Columbia, 2007)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Due to the advancement of nanotechnology, understanding the heat transport mechanism in nano-scale devices has become a crucial factor in describing the operation of the device...
A MEMS based Coulter counter for cell sizing
(University of Missouri--Columbia, 2007)
but also for in situ monitoring of cell dynamics. This research presents the design and fabrication of a MEMS based Coulter counter for monitoring cellular volumetric changes after an exposure to various media. The device is based on three important...
The development of electrohydraulic steering control system for off-road vehicle automatic guidance
(University of Missouri--Columbia, 2007)
dead-band and saturation. Dead-band influences steering accuracy very much. To remove it, a nonlinear compensation algorithm is developed and implemented in this research. The developed electrohydraulic steering control system is installed on a John...
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, psychological, and social...
Development of urban area geospatial information products from high resolution satellite imagery using advanced image analysis techniques
(University of Missouri--Columbia, 2004)
The latest generation of commercial satellite imaging sensors have a number of characteristics (e.g. high spatial resolution, multispectral bands, and quick revisit time), that make them ideal data sources for a variety of urban area applications...
Opto-electronic class AB microwave power amplifier using photoconductive switch technology
(University of Missouri--Columbia, 2006)
in a phased array radar system is the final power amplifier in each transmit-receive (TR) module. More recent final power amplifiers for TR modules have been configured in the Class AB or push-pull mode with a theoretical efficiency of 78...
Personalized functional health and fall risk prediction using electronic health records and in-home sensor data
(University of Missouri--Columbia, 2021)
obtained from TigerPlace, a senior living facility at Columbia, MO. The de-identification of this data was done using custom automated algorithms. The de-identified EHR data was used in several studies described in this dissertation. We then developed...
Automatic extraction of man-made objects from high-resolution satellite imagery by information fusion
(University of Missouri--Columbia, 2005)
extraction respectively, multiple detectors were developed and the extraction performance was greatly improved using multi-detector fusion from different information sources. For vehicle detection, a GIS road vector layer was used to incorporate contextual...
Design of a single sided linear induction motor (SLIM) using a user interactive computer program
(University of Missouri--Columbia, 2005)
This project studies the design of SLIM, which can be used to power capsules in a pneumatic capsule pipeline (PCP) system. The design equations of the SLIM and the equivalent circuit model are studied and discussed in detail. A SLIM of specified...
Robust receiver design for RF communication and underwater acoustic communication
(University of Missouri--Columbia, 2010)
with an important issue on equivalent discrete-time channel modeling, as the basis for other topics. Based on the proper channel modeling, a practical Doppler spread estimation method is proposed for mobile orthogonal frequency-division multiplexing (OFDM) systems...
Antenna designs and imaging algorithm for radar-based microwave breast cancer detection
(University of Missouri--Columbia, 2018)
presented. A tapered slot antenna and a quad-ridge horn antenna are designed, simulated and tested, and a system for multistatic radar-based microwave tumor detection for both artifact removal and image reconstruction was proposed. The system can...
Compact power conditioning and RF systems for a high power RF source
(University of Missouri--Columbia, 2008)
As part of the University Consortium for High Power Microwave (HPM) Integration, compact power conditioning and RF systems were investigated with a maximum diameter of 15.24 cm. A simulator of a flux compression generator (FCG) was built as a non...
Explainable data fusion
(University of Missouri--Columbia, 2021)
The recent resurgence of Artificial Intelligence (AI), specifically in the context of applications like healthcare, security and defense, IoT, and other areas that have a big impact on human life, has led to a demand for eXplainable AI (XAI...
Temporal decision making using unsupervised learning
(University of Missouri--Columbia, 2021)
are detected, and that new clusters are automatically formed as incoming data dictate. In this dissertation, we develop a streaming clustering algorithm, MU Streaming Clustering (MUSC), that is based on coupling a Gaussian mixture model (GMM) with possibilistic...
Investigation of the effects of body type on accelerometer based fall detection
(University of Missouri--Columbia, 2019)
Precision or personalized medicine follows the idea that analyzing a patient's genome can help stratify patients into treatment groups. Patients with cancer, for example, are split into groups based on the genetic make-up, rather than the location...
Investigation of the effects of body type on accelerometer based fall detection
(University of Missouri--Columbia, 2019)
[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI--COLUMBIA AT REQUEST OF AUTHOR.] Precision or personalized medicine follows the idea that analyzing a patient's genome can help stratify patients into treatment groups [1] [2]. Patients with cancer...
