Optimal Tracking In Switched Systems With Free Final Time And Fixed Mode Sequence Using Approximate Dynamic Programming, Tohid Sardarmehni, Xingyong Song

Mechanical Engineering Faculty Publications

Optimal tracking in switched systems with fixed mode sequence and free final time is studied in this article. In the optimal control problem formulation, the switching times and the final time are treated as parameters. For solving the optimal control problem, approximate dynamic programming (ADP) is used. The ADP solution uses an inner loop to converge to the optimal policy at each time step. In order to decrease the computational burden of the solution, a new method is introduced, which uses evolving suboptimal policies (not the optimal policies), to learn the optimal solution. The effectiveness of the proposed solutions is …

Nebraska Center for Biotechnology: Faculty and Staff Publications

Host innate immune response follows severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection, and it is the driver of the acute respiratory distress syndrome (ARDS) amongst other inflammatory end-organ morbidities. Such life-threatening coronavirus disease 2019 (COVID-19) is heralded by virus-induced activation of mononuclear phagocytes (MPs; monocytes, macrophages, and dendritic cells). MPs play substantial roles in aberrant immune secretory activities affecting profound systemic inflammation and end-organ malfunctions. All follow the presence of persistent viral components and virions without evidence of viral replication. To elucidate SARS-CoV- 2-MP interactions we investigated transcriptomic and proteomic profiles of human monocyte-derived macrophages. While expression of the …

D2gen: A Decentralized Device Genome Based Integrity Verification Mechanism For Collaborative Intrusion Detection Systems, Imran Makhdoom, Kadhim Hayawi, Mohammed Kaosar, Sujith Samuel Mathew, Pin-Han Ho

All Works

Collaborative Intrusion Detection Systems are considered an effective defense mechanism for large, intricate, and multilayered Industrial Internet of Things against many cyberattacks. However, while a Collaborative Intrusion Detection System successfully detects and prevents various attacks, it is possible that an inside attacker performs a malicious act and compromises an Intrusion Detection System node. A compromised node can inflict considerable damage on the whole collaborative network. For instance, when a malicious node gives a false alert of an attack, the other nodes will unnecessarily increase their security and close all of their services, thus, degrading the system’s performance. On the contrary, …

Assessing A Novel Adaptation To Cci Devices To Model Human Mild Traumatic Brain Injury, William R. Kochen, Kristen Craven, Rachel E. Barkey, Jane M. Flinn, David D. Cerri

Journal for Sports Neuroscience

Background: Traumatic Brain Injuries (TBIs) are a health crisis with over a million people suffering injuries each year in the United States. The majority of TBIs are mild injuries which often produce no period of unconsciousness and no gross damage to the brain or skull. A range of TBI animal models exist but many produce injuries too severe to characterize as mild. One TBI induction method commonly used is Controlled Cortical Impact (CCI) devices.

New Method: The purpose of this study is to assess a novel adaptation to CCI devices that allows for the induction of mild injuries that …

Examining Thermal Management Strategies For A Microcombustion Power Device, Bhanuprakash Reddy Guggilla, Jack Perelman Camins, Benjamin Taylor, Smitesh Bakrania

Henry M. Rowan College of Engineering Departmental Research

Microcombustion attracts interest with its promise of energy dense power generation for electronics. Yet, challenges remain to develop this technology further. Thermal management of heat losses is a known hurdle. Simultaneously, non-uniformities in heat release within the reaction regions also affect the device performance. Therefore a combination of thermal management strategies are necessary for further performance enhancements. Here, a bench top platinum nanoparticle based microcombustion reactor, coupled with thermoelectric generators is used. Methanol-air mixtures achieve room temperature ignition within a catalytic cartridge. In the current study, the reactor design is modified to incorporate two traditional thermal management strategies. By limiting …

Near-Field Imaging Of Plasmonic Nanopatch Antennas With Integrated Semiconductor Quantum Dots, Vasudevan Iyer, Yoong Sheng Phang, Andrew Butler, Jiyang Chen, Brian Lerner, Christos Argyropoulos, Thang Hoang, Benjamin Lawrie

Department of Electrical and Computer Engineering: Faculty Publications

Plasmonic nanopatch antennas that incorporate dielectric gaps hundreds of picometers to several nanometers thick have drawn increasing attention over the past decade because they confine electromagnetic fields to grossly sub-diffraction-limited volumes. Substantial control over the optical properties of excitons and color centers confined within these plasmonic cavities has already been demonstrated with far-field optical spectroscopies, but near-field optical spectroscopies are essential for an improved understanding of the plasmon–emitter interaction at the nanoscale. Here, we characterize the intensity and phase-resolved plasmonic response of isolated nanopatch antennas by cathodoluminescence microscopy. Furthermore, we explore the distinction between optical and electron beam spectroscopies of …

On The Need To Determine Accurately The Impact Of Higher-Order Sensitivities On Model Sensitivity Analysis, Uncertainty Quantification And Best-Estimate Predictions, Dan Gabriel Cacuci

Faculty Publications

This work aims at underscoring the need for the accurate quantification of the sensitivities (i.e., functional derivatives) of the results (a.k.a. “responses”) produced by large-scale computational models with respect to the models’ parameters, which are seldom known perfectly in practice. The large impact that can arise from sensitivities of order higher than first has been highlighted by the results of a third-order sensitivity and uncertainty analysis of an OECD/NEA reactor physics benchmark, which will be briefly reviewed in this work to underscore that neglecting the higher-order sensitivities causes substantial errors in predicting the expectation and variance of model responses. The …

Defamation Per Se Cases Should Include Guaranteed Minimum Presumed Damage Awards To Private Plaintiffs, Steven A. Krieger

San Diego Law Review

To combat the reputational harm associated with defamatory comments, forty states allow plaintiffs to recover presumed damages for reputational harm for defamatory statements considered “per se” defamation without having to prove the exact dollar figure associated with their reputational damages. While damages are presumed to a plaintiff’s reputation in a successful defamation per se lawsuit, the spectrum of presumed damages is so wide that there is almost no practical way for a plaintiff to reliably know the size of a presumed damages award, especially a lower-income plaintiff. Plaintiffs cannot evaluate the financial merit of a defamation lawsuit, which removes the …

Toxicology has been an active research field for many decades, with academic, industrial and government involvement. Modern omics and computational approaches are changing the field, from merely disease-specific observational models into target-specific predictive models. Traditionally, toxicology has strong links with other fields such as biology, chemistry, pharmacology and medicine. With the rise of synthetic and new engineered materials, alongside ongoing prioritisation needs in chemical risk assessment for existing chemicals, early predictive evaluations are becoming of utmost importance to both scientific and regulatory purposes. ELIXIR is an intergovernmental organisation that brings together life science resources from across Europe. To coordinate the …

The Post-Covid Future Of The Environmental Crisis Industry And Its Implications For Green Criminology And Zemiology, Thomas Raymen, O Smith

School of Law, Humanities and Social Sciences

Smith and Brisman (2020) have argued that our social and cultural orientation toward environmental crises is influenced by the existence of an ‘Environmental Crisis Industry’ (ECI hereafter) that favours environmental ‘solutions’ that are palatable to state corporate interests and the global consumer classes ahead of systemic change. This article, however, argues that the ECI is evolving in the context of political-economic and geopolitical changes that have emerged as a result of the Covid-19 pandemic, and is becoming increasingly focused on renewable energy and the shoring up supply and control over the minerals and natural resources crucial to the energy transition. …

Central Nervous System: Development, Function, And Applications Of The Glymphatic System (With Additional Neuroscience Topics), Austin Fisher

Theses

The presence of accumulated toxic protein aggregations such as amyloid-β, tau, and α- synuclein are implicated in the development of neurodegenerative diseases such as Alzheimer’s (Soto 2003). Thus, the clearance or removal of these harmful byproducts in healthy brain aging previously represented an unknown system whose functionality is likely to be clinically significant. The finding that directional flow of CSF and interstitial fluid through the brain ensures brain clearance sparked numerous research projects which sought to elaborate on what is now known as the glymphatic system. After initial research revealed the fundamentals of the glymphatic system, scientist J. Iliff defined …

Canopy Characteristics, Ingestive Behaviour And Herbage Intake In Cultivated Tropical Grasslands, Lynn E. Sollenberger, J. C. Burns

IGC Proceedings (1977-2023)

Compared to temperate systems, there have been few detailed assessments of canopy characteristics and associated grazing behavior in planted tropical grasslands. Reasons include the large number of forage species used in warm climates, the diversity of their morphology, research priorities emphasizing germplasm evaluation and management, and limited resources. This review describes canopy attributes of C₄ grass pastures, highlights the most important relationships between grazing behavior and these canopy characteristics, and discusses the implications of canopy characteristics and grazing behavior for long-term intake and animal performance. It is suggested that the largest differences in canopy characteristics between tropical and temperate …
