Combining Data-driven and Theory-guided Models in Ensemble Data Assimilation
There once was a dream that data-driven models would replace their theory-guided counterparts. We have awoken from this dream. We now know that data cannot replace theory. Data-driven models still have their advantages, mainly in computational efficiency but also providing us with some special …

Assessing, Modifying, and Combining Data Fields from the Virginia Office of the Chief Medical Examiner (OCME) Dataset and the Virginia Department of Forensic Science (DFS) Datasets in Order to Compare Concentrations of Selected Drugs
The Medical Examiner of Virginia (ME) dataset and the Virginia Department of Forensic Science Driving Under the Influence of Drugs (DUI) datasets were used to determine whether people have the potential to develop tolerances to diphenhydramine, cocaine, oxycodone, hydrocodone, methadone, and …

Burst Imaging with Learned Continuous Kernels
… them into one output image. By aligning and combining data from multiple frames, we can increase resolution, attenuate noise, reduce motion blur and expand the dynamic range to obtain a higher quality image. In this thesis, we propose a method that learns continuous kernels to process and …

An All-to-All Multicast Routing Protocol in a Wireless Ad-Hoc Network to Improve Channel Utilization
… scheme in this thesis will reduce overheads by combining data packets that are destined for the same mobile hosts. The action of combining jobs will be done at mobile hosts which are not joined in the multicasting group and only functioned as forwarders.</p>

Estimating the Discrepancy Between Computer Model Data and Field Data: Modeling Techniques for Deterministic and Stochastic Computer Simulators
… In many cases a researcher has access to data from a computer simulator and from a physical system. This research discusses Bayesian models that allow for the estimation of the discrepancy between the two data sources. We fit two models to data in the field of electrical engineering. Using …

Data fusion techniques for nondestructive evaluation and medical image analysis
<p>"Data fusion is a technique for combining data obtained from multiple sources for an enhanced detection or decision. Fusion of data can be done at the raw-data level, feature level or decision level. Applications of data fusion include defense (such as battlefield surveillance and autonomous …

The Shape of Seeing: An Ethnography of Phytolith Analysis
… or proxy, of the original plant context. Combining data from ethnographic methods with theory such as semiotics, enactment, and Actor Network Theory, this thesis proposes a model of decontextualization and recontextualization to explain how phytolith researchers translate meaning from one …

Data Augmentation and Conformal Prediction
… In this thesis, we explore the impact of data augmentation, a popular computer vision technique, on the performance of conformal predictors. In particular, we present multiple ways of combining data augmentation with conformal prediction by introducing five methods of …

Unified processing framework of high-dimensional and overly imbalanced chemical datasets for virtual screening.
… in drug discovery involves processing large datasets containing unknown molecules in order to find the ones that are likely to have the desired effects on a biological target, typically a protein receptor or an enzyme. Molecules are thereby classified into active or non-active in relation to …

Design and implementation of a microcomputer based Laboratory and Operations Information System (LOIS) for wastewater treatment plants
… (LOIS) were considered. Emphasis was placed on combining data generated by the laboratory and the operations divisions of the Alexandria Sanitation Authority. Goals were established to meet the information needs of key decision makers within the Authority and external information consumers such …

The laser mirror alignment system for the LHCb RICH detectors
… also describes the results of a unique method of combining data from the Laser Mirror Alignment Monitoring System and Tracking system, to recover the positions of all mirror segments in the RICH2 detector. The laser alignment monitoring system resolution has been measured to be 0.013 mrad for both …

A Framework for Autonomous Process Design: Towards Data-driven and Knowledge-driven Systems
… the problem of autonomous process design, by combining data-driven, knowledge-driven, and mathematical programming tools within a unified framework. To realise the intelligent system, the process design problem is first reformu- lated as a reinforcement learning problem, wherein an agent can …
