Multiscale Analysis Of Thermal Barrier Coated Cfrp Composites Under Thermal Loading, Devin Nielsen, Trenton M. Ricks, Juhyeong Lee

Mechanical and Aerospace Engineering Student Publications and Presentations

Carbon-fiber reinforced polymer (CFRP) composites are commonly used in high performance applications. Although offering several advantages (i.e., superior specific properties and improved structural rigidity), traditional CFRP composites often exhibit poor thermal stability due to a low matrix thermal decomposition temperature. The effective operating temperature of the CFRP composites can be raised by applying an outermost, protective thermal barrier coating (TBC) layer. Prefabricated high void content ceramic TBCs are ideal for composite applications due to their high thermal stability and relatively low thermal conductivity. In this paper, the thermo-mechanical response of the TBCCFRP composite laminate subjected to 500°C are assessed through …

The Phylogenetically Isolated South African Endemic Diving Beetle Caperhantus Cicurius (Fabricius, 1787): Redescription And Range Extensions (Coleoptera, Dytiscidae, Colymbetinae), David T Bilton, C.R. Turner, M.C. Mlambo

More Faculty of Science and Engineering Research

New distribution records and a redescription are presented for Caperhantus cicurius (Fabricius, 1787), a diving beetle endemic to the Cape region of South Africa, which is only distantly related to other Afrotropical dytiscids. We show that the species is much more widely distributed than previously recognized and present details of occupied habitats for the first time. Caperhantus cicurius occurs throughout the winter rainfall zone in South Africa, from Namaqualand to the Eastern Cape Province, particularly in temporary waters in the Fynbos and Succulent Karoo biomes.

Origami And Kirigami-Inspired Sandwich Panels For Uam Primary Structural Applications, Kalyan Raj Kota, Juhyeong Lee

Mechanical and Aerospace Engineering Faculty Publications

Foldcore sandwich panels (FSPs) provide highly tailorable structural and multifunctional performance over legacy sandwich panels made with honeycomb or foam cores. In FSP manufacturing, skins and foldcore are made from any flat sheets of unitary or hybrid materials, folded into a desired pattern. Two common folding mechanisms include origami and kirigami: origami core is involved with folding only, while kirigami core is associated with a strategic combination of folding and cutting. Material and core geometry can be determined to satisfy the applications’ performance requirements. Overall, origami- or kirigami-inspired FSPs have the potential to revolutionize the ways to design and …

2020-Current year OA Pubs

Autosomal dominant polycystic kidney disease (ADPKD) is the most common hereditary kidney disease and causes significant morbidity, ultimately leading to kidney failure. PKD pathogenesis is characterized by complex and dynamic alterations in multiple cell types during disease progression, hampering a deeper understanding of disease mechanism and the development of therapeutic approaches. Here, we generate a single-nucleus multimodal atlas of an orthologous mouse PKD model at early, mid, and late timepoints, consisting of 125,434 single-nucleus transcriptomic and epigenetic multiomes. We catalog differentially expressed genes and activated epigenetic regions in each cell type during PKD progression, characterizing cell-type-specific responses to

Advancing Data-Driven Disaster Debris Characterization And Quantification, Jasmine Bekkaye

LSU Doctoral Dissertations

Natural hazards generate tremendous amounts of debris that negatively impact communities and overwhelm waste management infrastructure. The challenge in disaster debris planning and management stems from inconsistent and scarce post-disaster debris quantity data due to the chaotic nature of recovery operations. This leads to a limited understanding of key factors influencing disaster debris generation across hazards and regions, hindering the accuracy and efficiency of modeling. With the increasing availability of comprehensive post-disaster waste datasets, the capacity to understand debris generation is expanding. This dissertation aims to fill knowledge gaps on disaster debris generation as follows: (1) investigate existing technologies for …

Giving Our “Paper Tiger” Real Teeth: Fixing The U.S. Military’S Plans For Contested Logistics Against China, Zachary S. Hughes

Joint Force Quarterly

This article argues that the U.S. military’s emerging concepts for dispersed operations in the Western Pacific risk becoming unsustainable because logistics has not been fully integrated into force design and campaign planning. Focusing on a potential conflict with China, the author contends that logistics would likely be a decisive factor, particularly in scenarios involving a blockade or invasion of Taiwan and operations inside China’s antiaccess/area-denial network. The article reviews the logistical demands of Marine Corps Expeditionary Advanced Base Operations, Army multidomain task forces, and Air Force Agile Combat Employment, finding that each concept creates significant sustainment challenges and often shifts …
