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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
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...
