Non-destructive Evaluation of Food Products by Microwave and mmW Imaging
… major concern in the food industry, as physical contamination can pose significant health risks to consumers, damage brand reputation, and lead to legal consequences. Common detection methods, such as X-ray inspection, have limitations, particularly in identifying contaminants like plastic, wood, …

Analysis and design of an in-pipe system for water leak detection
… environmental health disasters due to delay in detection of water pipeline leaks have spurred research into the development of methods for pipeline leak and contamination detection. This thesis is on the analysis and design of a floating mobile sensor for leak detection in water distribution …

Genome diversity and evolution in canine transmissible venereal tumour
… a qPCR-based assay for CTVT diagnosis and host contamination detection. With the goal of tracing the historical spread of CTVT and learning about the genetic diversity of this disease, I sequenced complete mitochondrial genomes of 449 CTVT tumours and their matched hosts. The analysis of the …

Liner characterisation and leak detection using electrical resistivity techniques
… was found with distance/depth for Bayer liquor contamination as observed with other leachates. Therefore, the installation of this innovative detection system below the liners in the aluminium industry can enable the effective monitoring of the lining systems and in case of failures, to take …

Modeling and Estimation Techniques for Wide-Area Network Traffic with Atypical Components
… with parsimonious analytic traffic models. A detection and modeling technique is presented and studied for atypical traffic characterized by strongly clustered inliers. This technique is found to be effective using both real-world observations and simulated data. Another form of atypical …

Quantitative dynamics of T-cell receptor repertoires and their use for cancer patient stratification
… developed a statistical framework for the robust detection of individual TCR clones that behave in non-neutral way, which could be indicative of immune activation and response. We then applied this framework in Chapter 3 to a dataset of longitudinal TCR repertoire samples taken over the period of …

Data Analytics and Machine Learning Applications in Fermentation Processes and Molecular Property Prediction
… machine learning models to predict and reduce contamination risk. For the first project, MPLS methods are used to develop interpretative correlation models to monitor the foaming occurrence and, hence, improve batch fermentation. The exhaust differential pressure is chosen as a quality variable …

Combining Chemometrics and non-target GC-IMS gas phase analysis for improved bioprocess monitoring
… as a suitable algorithm for automated peak detection in two-dimensional GC-IMS data. Its performance was evaluated on two publicly available datasets with different GC setups, peak shapes, and resolution. The utilization of certain preprocessing methods, mainly asymmetric least squares …

Polymer and covalent functionalization of single walled carbon nanotubes for electronic sensor applications
In this thesis, chemiresistive devices for the detection of volatile organic compounds to include chemical warfare agents are developed. Active sensing materials were produced by crafting composites of synthetic polymers and single walled carbon nanotubes. Sensitivity to and selectivity for target …

Unveiling Origins and Dynamics of Fecal Indicator Bacteria in an Urban Creek
… waterways are highly vulnerable to bacterial contamination, which presents significant risks to public health and water quality. Common methodologies typically measure the total concentration of fecal indicator bacteria (FIB) but are unable to address the complex sources of contamination …
