Online Teaching and Learning Strategies
- Location: Online
- Contact: CITS Instructional Development
- Description: A rigorous four-week, fully online certification course that introduces faculty to the current research and best practices for online teaching and learning. Using their own discipline-specific course materials for activities, faculty will work independently, collaboratively with peers from across campus, and with Instructional Designers to design and build one unit of online instruction in a myCourses site. This unit will meet the Quality Online Course Review Rubric criteria and be a model that faculty can reference and replicate as they continue to develop their upcoming fully online course(s).

SPEAKER:
Dr. Shabnam Raayai, Rowland Fellow, Rowland Institute at Harvard University
TOPIC:
Dynamics of Flow Past Textures and Arrays Inspired by Sharks and Pelicans
ABSTRACT:
Nature uses geometry in fascinating ways to optimize flow fields: one example is the ribs on overlapping denticles on shark skin which allow sharks to swim faster than other animals in the ocean. Another is the case of formation flight used by groups of pelicans to minimize the energy required for flying (per pelican) compared to flying solo. In this talk, I will explore the effect of complex geometries and arrangements of solid boundaries on the flow field. First, I will focus on shark-inspired two-dimensional, symmetric, and periodic textures of various cross-sectional shapes (commonly known as riblets) which are placed aligned with the direction of the flow. Second, I will explore the effect of using arrangements of objects in the flow inspired by formation flight in pelicans and the interactions between flow past various members. I will describe the results of our custom-designed experiments using a combination of Taylor-Couette flows in Couette flow and Taylor-Vortex regimes and high Reynolds number laminar boundary layer flows in a water tunnel. I will discuss how each of these complex geometries and arrangements can be used to tune the flow field around the boundaries in terms of frictional loading, and flow instabilities.

ELE Master of Science Thesis Defense by Adam Harte

- Description: Topic: Implementation of Analog Electronic Hardware for Training Neural
Networks
Location: LC Conference Room, Science & Engineering Building (SENG), Room 213A
Zoom Conference Link: https://umassd.zoom.us/j/95661551262
Meeting ID: 956 6155 1262 Passcode: 645260
Abstract:
Most current training methods for Artificial Neural Networks (ANNs) run as software emulations, as opposed to an on-chip training approach. Although it is convenient to have training done through software as opposed to on a hardware build, there are several drawbacks to this approach. The primary cost of this convenience is the amount of time it takes to train an ANN. Emulated training methods are slower than real-time on-chip training, with the amount of training time increasing with the complexity of the ANN. When training in real-time each neuron can be trained at once, taking advantage of the inherent parallelism of ANNs, and decreasing training times markedly.
This thesis includes a discussion of an analog hardware implementation for training neural networks, and an evaluation and design explanation of an ANN which has been built on physical hardware as a proof-of-concept. The ANN is designed to perform pattern recognition on handwritten digits from zero to nine and uses the MNIST data set as a source for the figures used in training. The “output-layer†section of this ANN, where all of the training is completed, is built entirely in analog hardware in order to prove the potential advantages over training in software.

Abstract:
This doctoral dissertation discusses the basic dynamics of the mesoscale cyclonic quasi-stationary meanders of the Brazil Current and their impact on plankton distribution off SE Brazil. The wind-driven coastal upwelling systems in the region promote intrusions of nutrient-rich waters onto the continental shelf, supported by coastal divergence induced by the meanders. We perform experiments in a 1.5-layer quasi-geostrophic (QG) model based on contour dynamics coupled to a Nutrients-Phytoplankton-Zooplankton (NPZ) model. The results suggest that mesoscale activity impacts the planktonic populations off SE Brazil. \textit{In situ} observations of these phenomena are scarce. We present an unprecedented sampling effort that revealed submesoscale processes in a meander's rim. We show the biota responds to different dynamic regimes in distinct parts of the feature. Inspired by the observations, we choose to build a hierarchy of idealized models coupled to an NPZ model to investigate physical-biological interactions at mesoscale and submesoscale. We use a 2-layer QG model also based on contour dynamics, showing the meanders' stationarity is due to the almost pure baroclinic nature of this system. The lateral stirring transports enriched waters offshore, impacting the NPZ fields in addition to the eddy-induced upwelling. Then, a continuously stratified model is used to investigate submesoscale dynamics. The results suggest that submesoscale processes increase the heterogeneity in the NPZ distribution, with preferred areas for enhanced biological activity shifting from the eddy center in a 10 km resolution experiment to the eddy rim in a 1 km resolution experiment. Lastly, we briefly investigate strong biases in sea surface temperature (SST) during coastal upwelling events.
