Application Of Observability In Performance Evaluation Of Photosynthesis Model, Hongnai Gao, Lijiang Fu, Qian Xia, Ya Guo

Journal of System Simulation

Abstract: The photochemical reaction of photosynthesis involves a variety of physiological substances that cannot be directly measured. By modeling the control system, the state of these physiological substances can be es-timated based on the chlorophyll fluorescence, but the reliability of the state estimation is not given in all the reference documents. In response to this problem, based on the photochemical reaction kinetic model, the observability of the nonlinear system is introduced to evaluate the reliability of the state estimation. Aiming at the existing observability methods lacking the direct comparability due to the different dimensions of the components of different states, …

Western Kentucky University Stormwater Utility Survey 2022, Warren Campbell

SEAS Faculty Publications

The main goal of this survey is to identify as many U.S. Stormwater Utilities (SWUs) as possible. Because many stormwater professionals do not have the time to respond to questionnaires, our primary method of identification was Internet searches. We searched on key terms such as “stormwater utility”, “stormwater fee”, and “drainage fee”. We scoured on-line municipal codes such as Municode, AmLegal, Sterling, LexisNexis, General Code, and others. We searched through many city web sites trying to find utilities. We have also had many people contact me to update fees and identify new utilities. However, the data primarily comes from Internet …

Machine Learning Prediction Of Glass Transition Temperature Of Conjugated Polymers From Chemical Structure, Amirhadi Alesadi, Zhiqiang Cao, Zhaofan Li, Song Zhang, Haoyu Zhao, Xiaodan Gu, Wenjie Xia

Faculty Publications

Predicting the glass transition temperature (Tg) is of critical importance as it governs the thermomechanical performance of conjugated polymers (CPs). Here, we report a predictive modeling framework to predict Tg of CPs through the integration of machine learning (ML), molecular dynamics (MD) simulations, and experiments. With 154 Tg data collected, an ML model is developed by taking simplified “geometry” of six chemical building blocks as molecular features, where side-chain fraction, isolated rings, fused rings, and bridged rings features are identified as the dominant ones for Tg. MD simulations further unravel the fundamental roles …

Microheater Stimulation Platform For Neural Cells, Haley Royce Jun 2022

Microheater Stimulation Platform For Neural Cells, Haley Royce

USF Tampa Graduate Theses and Dissertations

Electrical stimulation is the basis of many biomedical devices like cochlear implants,pacemakers, and retinal implants. In these systems, current is applied to a desired tissue to effectively stimulate it. Unfortunately, this is not localized as the current will spread through the tissue, limiting the spatial resolution. Thus, alternative forms of stimulation are needed to improve device precision and resolution. This project explores microheaters as a stimulation platform that can be easily integrated with existing biomedical devices. Microheaters produce heat via the Joule heating effect wherein electrical current is run through high resistance materials to output thermal energy. They are highly …

Tensile Strain And Damage Self-Sensing Of Flax Frp Laminates Using Carbon Nanofiber Conductive Network Coupled With Acoustic Emission, Yanlei Wang, Guipeng Chen, Yongshuai Wang, Baoguo Han, Baolin Wan, Qingduo Hao, Yulei Bai

Civil and Environmental Engineering Faculty Research and Publications

The strain and damage self-sensing properties of carbon nanofibers (CNFs)/flax fiber-reinforced polymer (FFRP) laminates under tension were investigated via simultaneously measuring the changes of electrical resistance (ER) and acoustic emission (AE) signals. The piezoresistive mechanisms together with the damage evolution of CNFs/FFRP laminates were also explored. The results revealed that both ER and AE responses to tensile strains in CNFs/FFRP laminates could be segmented into three stages, which confirmed their good damage self-sensing ability. The isochronous and reversible electrical resistance responses to tensile strains proved the stability and repeatability of strain self-sensing capability for CNFs/FFRP laminates. Moreover, in-situ ER measurement …

Why We Should Reuse Wastewater, Bridget Sarver Jun 2022

Why We Should Reuse Wastewater, Bridget Sarver

Certified Public Manager® Applied Research

As population and industry grow, the need to reuse wastewater is growing. Aquifers are often the dominant water supplies to surrounding areas. The levels of those aquifers are declining each year. Water loss affects many things like water wells, lakes, and rivers. Lakes and rivers that are used as water sources are seeing a decline in levels. Low water levels and drought occur because of the changing water cycle. Heavy rain and runoff can help refill lakes and rivers; however precipitation does not always fall back on the area that it evaporated from. By reusing wastewater, we will be saving …

A Porosity-Based Model Of Dynamic Compaction In Under-Dense Materials, John A. Moore, Nathan R. Barton Jun 2022

A Porosity-Based Model Of Dynamic Compaction In Under-Dense Materials, John A. Moore, Nathan R. Barton

Mechanical Engineering Faculty Research and Publications

Under-dense metals including micro-architectured structures and stochastic foams provide a combination of low weight, high strength-to-weight ratio, high permeability, and low stiffness, which make them desirable materials for a variety of applications. Specifically, their energy absorption capabilities under dynamic compressive loads are desirable. However, under high loading rates there are several challenges in performing accurate simulations of under-dense materials—primarily, the responses of materials with high, low, and zero porosity are difficult to accurately predict with a single model. A general model that tracks porosity and pore geometry and is flexible for a variety of matrix material constitutive responses has yet …

A Simplified Model For The Intermediate Structure Of Strong Fire Whirls, Forman A. Williams Jun 2022

A Simplified Model For The Intermediate Structure Of Strong Fire Whirls, Forman A. Williams

Progress in Scale Modeling, an International Journal

A model is described for the overall structure of intense fire whirls, based on a spatially evolving vortex, with circulation enhancement driven by the axial acceleration of low-density gas in the core through the axial pressure gradient. The axial acceleration increases the entrainment rate into the core which, through mass conservation, increases the circulation if the angle between the tangential and radial velocity components remains fixed. The two-zone model employs general balance equations for regions inside and outside a cylinder of fixed radius, each inviscid, the inside region being presumed to have a constant density small compared with the (constant) …
