(2021-11-19)Department: BiostatisticsObservational studies with time-to-event outcomes in electronic healthcare records have been widely used to estimate the effects of treatments, exposures, and medical interventions on health outcomes in a typical clinical ...
-
(2021-01-11)Department: Mechanical EngineeringThe ability to estimate musculoskeletal dynamics (e.g., forces, stress and motion of individual muscles, bones and tendons) provides numerous scientific, societal, and clinical opportunities. Over the past few decades, new ...
-
(2019-03-26)Department: Special EducationMany students with severe disabilities are included in the general education classroom for some part of their instructional day. General educators rarely receive strong training to support these students and need guidance ...

(Vanderbilt University, 2016-04-25)The Children's Report of Parental Behavior Inventory is a widely used three-dimensional psychometric measure to assess parenting behaviors as reported by children and parents. Parent-child dyads tend to report discrepant ...
-
(Endoscopy International Open, 2019-09)Background and study aims Our academic lab has developed a novel, low-cost, disposable endoscope for assessment of the esophagus and stomach without need for large equipment or complex electronics. Usability and intuitiveness ...
-
(2007-08-03)Department: Biomedical InformaticsThe aims of this project are to 1) build and evaluate a terminology that provides categorization labels, or tags, for common segments within clinical documents, and 2) to evaluate a tool to parse and label natural-language ...
-
(2012-08-06)Department: Biomedical InformaticsThis thesis describes two studies evaluating the utility, discrimination and validity of an outpatient mortality risk score using an electronic adaptation of the Lee 4-year mortality risk model. In our initial study we ...
-
(2013-07-30)Department: PhysicsIn the first part of this dissertation, I look at (1) the possibility of using a conventional x-ray source for phase-contrast digital tomosynthesis, (2) that the reconstructed tomosynthesis images demonstrate and retain ...
-
(2012-05-04)Department: Biomedical EngineeringImage guidance utilizes a rigid registration between the preoperative images and physical space of the operating room and it is now the standard of care in neurosurgical procedures. The fidelity of the image guidance system ...
-
(2013-03-01)Department: ChemistryThe most common approaches to treatment of cancer are chemo- and radiation-therapies that cause DNA damage. The efficiency of these treatments is reduced over time because cells up-regulate DNA damage response and repair. ...
-
(2021-12-02)Department: Biomedical InformaticsMany clinical natural language processing (NLP) methods rely on non-contextual or contextual word embedding models. Yet, few intrinsic evaluation benchmarks exist comparing embedding model representations against human ...

(2020-03-31)Department: Computer ScienceNavigation is an everyday activity. It consists of knowing where you are, knowing where you want to go, and choosing some way to get there. This way is referred to as locomotion or a locomotion method. As we locomote we ...
-
(Advances in Therapy, 2019-09)Introduction As continuous exposure to anticholinergics has been associated with adverse outcomes, accurately measuring exposure is important. However, no gold standard measure is available, and the performance of existing ...
-
(2015-03-31)Department: BiostatisticsA general rule of thumb for survival analysis is to have at least 15 events per variable in order to produce reliable inference in terms of accuracy and precision of regression coefficient estimates. Sometimes, even well ...
-
(2009-01-12)Department: Electrical EngineeringAbstract This thesis evaluates the performance of two non-rigid image registration techniques. The Moving Least Squares (MLS) technique is compared to the widely used Thin-plate Spline (TPS) method. Both methods interpolate ...
