Non-invasive detection of oral cancer using reflectance and fluorescence spectroscopy
… the spectral parameters and tissue anatomy. Diagnostic algorithms for distinguishing various lesion categories were then developed using data collected from patients. The healthy volunteer study demonstrated that tissue anatomy has a strong influence on the spectral parameters. Anatomic sites …

Development of a real time trimodal spectroscopy diagnostic tool for Barrett's esophagus
… and biochemistry. Using this information, diagnostic algorithms will be developed, optimized and displayed to the physician through a useful interface.

Differential light scattering spectroscopy measurements for detecting and imaging cancer
… /LSS to interrogate colon tissue and to develop diagnostic algorithms based on Mie theory. The results show great promise for diagnosing cancer. Instrumentation is being developed to implement SD/LSS and /LSS together in a wide area imaging system with the goal of studying and detecting cancer at …

Quantitative spectroscopy for detection of cervical dysplasia
… conducted by experts, is subject to significant diagnostic variability. The aim of the work presented in this thesis was to develop a non-invasive clinical tool for detection of cervical HSIL and for guiding the biopsy during colposcopy. Previously we have developed a contact-probe portable …

Model-based fault detection and diagnosis of selective catalytic reduction systems for diesel engines
… is also required to be monitored by the On-Board Diagnostics (OBD) regulations. Specifically, a diagnostic algorithm is required to detect and isolate the SCR system faults that may cause emission violation. In this research, two model-based fault detection and isolation algorithms are developed …

Evaluation of the Diagnostic Performance of Lung Ultrasound Compared to Chest X-rays for Diagnosis of Pneumonia in Children
… resistance. Addition of chest X-ray (CXR) to diagnostic algorithms improves specificity, but CXR use is limited by radiation exposure and relatively high costs, limiting access in low-resource settings. Current guidelines therefore reserve CXR for moderate to severe disease and hospitalised …

Impact of family history of premature coronary disease on carotid ultrasound and coronary calcium findings
… that will go above and beyond the current diagnostic algorithms.

Surface Enhanced Raman Spectroscopy for Diagnostics in Ocular Health
… that present significant challenges for clinical diagnostics due to their resistance to antimicrobial treatments and their evasion of traditional detection techniques. By amplifying Raman signals through metal nanoparticles, SERS offers a promising solution for overcoming these challenges in …

Structure and agency in the economics of public policy for TB control
… of healthcare workers mediates the value of TB diagnostic algorithms, and how this may affect the costs, outcomes as well as the economic burden associated with the disease in South Africa. The work presented is based on empirical work done alongside a pragmatic cluster randomized control trial. …

Design and validation of mobile kit and machine learning algorithms for pulmonary disease screening and diagnosis
… of pulmonary disease, we built a pulmonary diagnostic kit that consists of an electronic stethoscope, an augmented reality peak flow meter, and an electronic questionnaire. Using this kit, we collected data from patients who visited the Chest Research Foundation, a pulmonary clinic in Pune, …

System Level Approach towards Intelligent Healthcare Environment
… could lead to unintended consequences. In-vivo diagnostics and imaging (the Gastro-Intestinal tract) has shown to be inconvenient for the patients using traditional endoscopic instruments and often these conventional methods are limited in terms of their access to various organs (e.g. small …

Diversity of vaginal microbiota associated with bacterial vaginosis and the impact on pregnancy outcomes in HIV-infected and uninfected women.
… outcomes could lead to interventions or diagnostic algorithms to prevent and predict these outcomes in this population. We recruited 420 pregnant Zimbabwean women [48 (11.4%) HIV infected, 372 (88.6%) HIV uninfected], between 13-35 weeks of gestation with a median gestational age of 30 …
