Integrating Multiple Survey Techniques To Document A Shifting Bat Community In The Wake Of White-Nose Syndrome, D. Scott Reynolds, Kevin Shoemaker, Susi Von Oettingen, Stephen Najjar, Jacques P. Veilleux, Paul R. Moosman Jr

KIP Articles

The long-term study of bat communities often depends on a diverse set of sampling methodologies that are chosen based on the species or habitat management priorities of the research project. Integrating the data from a diverse set of methodologies (such as acoustic monitoring and mist net sampling) would improve our ability to characterize changes in community structure or composition over time, such as one would expect following an emergent infectious disease such as white-nose syndrome. We developed a Bayesian state-space model to integrate these disparate data into a common currency (relative abundance). We collected both acoustic monitoring and mist net …

Anomaly Detection And Failure Prediction In Gas Turbines, Vipul Goyal

Electronic Theses and Dissertations, 2020-2023

This study is based on time-series data taken from the combined cycle heavy-duty utility gas turbines. For analysis, first, a multi-stage vector autoregressive model is constructed for the nominal operation of powerplant assuming sparsity in the association among variables, and this model is used as a basis for anomaly detection and prediction. This prediction is compared with the time-series data of the powerplant test data containing anomalies. Granger causality networks, which are based on the associations between the time series streams, can be learned as an important implication from the vector autoregressive modelling. This method suffers from the disadvantage that …

Investigating The Role Of The Skeletal Muscle In Amyotrophic Lateral Sclerosis Neuromuscular Junction Dysfunction, Agnes Badu-Mensah

Electronic Theses and Dissertations, 2020-2023

Neuromuscular junction (NMJ) dysfunction has been identified as one of the earliest events in Amyotrophic Lateral Sclerosis (ALS) pathology. However, which tissue type induces NMJ disruption; be it the motoneurons (hMN), Schwann cells or skeletal muscle (hSKM) remains unresolved. While mechanisms by which ALS hMN contribute to NMJ dysfunction are well-described in literature, limited information exist on how the other tissue types in the tripartite synapse (hSKM and Schwann cells) induce and/or contribute to ALS NMJ disruption. A fair understanding of the role of each tissue type in NMJ dysfunction would help shape the trajectory of future ALS research and …

Map-Gan: Unsupervised Learning Of Inverse Problems, Brandon S. Campanella

Master's Theses

In this paper we outline a novel method for training a generative adversarial network based denoising model from an exclusively corrupted and unpaired dataset of images. Our model can learn without clean data or corrupted image pairs, and instead only requires that the noise distribution is able to be expressed analytically and that the noise at each pixel is independent. We utilize maximum a posteriori estimation as the underlying solution framework, optimizing over the analytically expressed noise generating distribution as the likelihood and employ the GAN as the prior. We then evaluate our method on several popular datasets of varying …

Triangular Cosserat Point Element Method For Reducing Soft Tissue Artifact: Validation And Application To Gait, Jake Edward Deschamps, Stephen Klisch

Master's Theses

Human motion capture technology is a powerful tool for advancing the understanding of human motion biomechanics (Andriacchi and Alexander, 2000). This is most readily accomplished by applying retroreflective markers to a participant’s skin and tracking the position of the markers during motion. Skin and adipose tissue move independently of the underlying bone during motion creating error known as soft tissue artifact (STA), the primary source of error in human motion capture (Leardini et al., 2005).

(Solav et al., 2014) proposed and (Solav et al., 2015) expanded the triangular Cosserat point element (TCPE) method to reduce the effect of STA on …
