Energy-Aware Path Planning For Fixed-Wing Seaplane Uavs, Benjamin Atkinson Wolsieffer

Dartmouth College Master’s Theses

Fixed-wing unmanned aerial vehicles (UAVs) are commonly used for remote sensing applications over water bodies, such as monitoring water quality or tracking harmful algal blooms. However, there are some types of measurements that are difficult to accurately obtain from the air. In existing work, water samples have been collected in situ either by hand, with an unmanned surface vehicle (USV), or with a vertical takeoff and landing (VTOL) UAV such as a multirotor. We propose a path planner, landing control algorithm, and energy estimator that will allow a low-cost and energy efficient fixed-wing UAV to carry out a combined remote …

Tunneling Time And Faraday/Kerr Effects In Pt-Symmetric Systems, Peng Guo, Vladimir Gasparian, Antonio Antonio Perez-Garrido, Ester Jodar Ferrandez

Research & Publications

We review the generalization of tunneling time and anomalous behaviour of Fara- day and Kerr rotation angles in parity and time (PT )-symmetric systems. Similarities of two phenomena are discussed, both exhibit a phase transition-like anomalous behaviour in a certain range of model parameters. Anomalous behaviour of tunneling time and Faraday/Kerr angles in PT -symmetric systems is caused by the motion of poles of scattering amplitudes in the en- ergy/frequency complex plane.

Self-Supervised Deep Clustering Of Single-Cell Rna-Seq Data To Hierarchically Detect Rare Cell Populations., Tianyuan Lei, Ruoyu Chen, Shaoqiang Zhang, Yong Chen

College of Science & Mathematics Departmental Research

Single-cell RNA sequencing (scRNA-seq) is a widely used technique for characterizing individual cells and studying gene expression at the single-cell level. Clustering plays a vital role in grouping similar cells together for various downstream analyses. However, the high sparsity and dimensionality of large scRNA-seq data pose challenges to clustering performance. Although several deep learning-based clustering algorithms have been proposed, most existing clustering methods have limitations in capturing the precise distribution types of the data or fully utilizing the relationships between cells, leaving a considerable scope for improving the clustering performance, particularly in detecting rare cell populations from large scRNA-seq data. …

Cognitive Neuropsychology Of Autism, Attention- Deficit Hyperactivity Disorders And The Role That Neurodivergence Plays On Social Skills, Cognition And Behavior., Madison Mckee

D.U.Quark

Many studies have investigated how structural abnormalities directly affect the brain, but few have sought to understand the experience of living with neurodivergence. Two common neurodivergent disorders, Autism and ADHD, result from an abnormal development in the frontal lobe, caudate and corpus callosum. Disruptions in these areas have inhibitory effects on behavior and nerve signaling which results in deficits in executive functioning and Theory of Mind (ToM). The presence of these disruptions provides evidence that neurodevelopmental conditions are as physical as they are enduring. The purpose of this paper is to analyze the cognitive and behavioral deficits of Autism and …
