Convolutional-Neural-Network-Based Des-Level Aerodynamic Flow Field Generation From Urans Data, John P. Romano, Oktay Baysal, Alec C. Brodeur Jan 2023

Convolutional-Neural-Network-Based Des-Level Aerodynamic Flow Field Generation From Urans Data, John P. Romano, Oktay Baysal, Alec C. Brodeur

Mechanical & Aerospace Engineering Faculty Publications

The present paper culminates several investigations into the use of convolutional neural networks (CNNs) as a post-processing step to improve the accuracy of unsteady Reynolds-averaged Navier–Stokes (URANS) simulations for subsonic flows over airfoils at low angles of attack. Time-averaged detached eddy simulation (DES)-generated flow fields serve as the target data for creating and training CNN models. CNN post-processing generates flow-field data comparable to DES resolution, but after using only URANS-level resources and properly training CNN models. This document outlines the underlying theory and progress toward the goal of improving URANS simulations by looking at flow predictions for a class of …


Riverine Carbon Cycling Over The Past Century In The Mid‐Atlantic Region Of The United States, Yuanzi Yao, Hanqin Tian, Shufen Pan, Raymond G. Najjar, Marjorie A.M. Friedrichs, Zihao Bian, Hong-Yi Li, Eileen E. Hofmann Jan 2021

Riverine Carbon Cycling Over The Past Century In The Mid‐Atlantic Region Of The United States, Yuanzi Yao, Hanqin Tian, Shufen Pan, Raymond G. Najjar, Marjorie A.M. Friedrichs, Zihao Bian, Hong-Yi Li, Eileen E. Hofmann

CCPO Publications

The lateral transport and degassing of carbon in riverine ecosystems is difficult to quantify on large spatial and long temporal scales due to the relatively poor representation of carbon processes in many models. Here, we coupled a scale‐adaptive hydrological model with the Dynamic Land Ecosystem Model to simulate key riverine carbon processes across the Chesapeake and Delaware Bay Watersheds from 1900 to 2015. Our results suggest that throughout this time period riverine CO2 degassing and lateral dissolved inorganic carbon fluxes to the coastal ocean contribute nearly equally to the total riverine carbon outputs (mean ± standard deviation: 886 ± …


Vintage 2020: Rogue Valley Reference Vineyard Report, Gregory V. Jones Jan 2021

Vintage 2020: Rogue Valley Reference Vineyard Report, Gregory V. Jones

Linfield University Wine Studies Reports

This report describes the impacts of climate and phenology on vintage for the Rogue Valley in Oregon in 2020. A mild and dry winter in 2019-20 was followed by a dry growing season continuing the ongoing drought concerns for Oregon and the majority of the western US. The spring was relatively cool with mild frosts into early May, then followed by wide swings between early season heat then cool, wet conditions leading up to and during flowering. The result was widespread issues with fruit set leading to generally high amounts of shatter, smaller berries and clusters for many in the …

The result was widespread issues with fruit set leading to generally high amounts of shatter, smaller berries and clusters for …


Homestead National Monument Of America, Acoustic Monitoring, 2011-2012 Feb 2020

Homestead National Monument Of America, Acoustic Monitoring, 2011-2012

United States National Park Service: Publications

Executive Summary

This report presents acoustical data gathered by Student Conservation Association interns and the Natural Resource Specialist at Homestead National Monument of America in 2011 and 2012. Data were collected at four sites to provide park managers with information on the acoustical environment, sources of noise, and the existing ambient sound levels within the monument. The data will also inform the park managers with information regarding the potential impact of traffic on Highway 4.

Monitoring occurred at each site during two different seasons (except HOME002) in order to document seasonal variations. In each deployment, sound pressure level (SPL) was …

Economic Contributions Of Winter Sports In A Changing Climate, Hagenstad Consulting, Inc., Elizabeth Burakowski, Rebecca Hill Feb 2018

Economic Contributions Of Winter Sports In A Changing Climate, Hagenstad Consulting, Inc., Elizabeth Burakowski, Rebecca Hill

Earth Systems Research Center

In mountain towns across the United States that rely on winter tourism, snow is

currency. For snow lovers and the winter sports industry, predictions of a future with

warmer winters, reduced snowfall, and shorter snow seasons is inspiring them to

innovate, increase their own efforts to address emissions, and speak publicly on the

urgent need for action.

This report examines the economic contribution of winter snow sports tourism to

U.S. national and state-level economies. In a 2012 analysis, Protect Our Winters and

the Natural Resources Defense Council found that the winter sports tourism industry

generates $12.2 billion and 23 million …
