Asymmetric Secondary Flows Above Geometrically Symmetric Surface Roughness, Wen Zhang, Xiang Yang, Xiaowei Zhu, Minping Wan, Shiyi Chen

Mechanical and Materials Engineering Faculty Publications and Presentations

The mean flow behaviour of a turbulent boundary layer over rough walls is expected to exhibit symmetries that govern the flow dynamics. In particular, when roughness elements are arranged in a spanwise symmetric manner, the mean flow above them should also exhibit spanwise symmetry. This symmetrical consideration has garnered substantial empirical support. We conduct direct numerical simulations (DNS) of flow over aligned cube arrays to test such symmetry considerations further. We vary the surface coverage density from 0.25 % to 6.25 %, and employ an averaging time of about 100 large-eddy turnover times, which is longer than the typical averaging …

Reconstructing 42 Years (1979–2020) Of Great Lakes Surface Temperature Through A Deep Learning Approach, Miraj Kayastha, Tao Liu, Daniel Titze, Timothy C. Havens, Chenfu Huang, Pengfei Xue

Michigan Tech Publications

Accurate estimates for the lake surface temperature (LST) of the Great Lakes are critical to understanding the regional climate. Dedicated lake models of various complexity have been used to simulate LST but they suffer from noticeable biases and can be computationally expensive. Additionally, the available historical LST datasets are limited by either short temporal coverage (<30 >years) or lower spatial resolution (0.25° × 0.25°). Therefore, in this study, we employed a deep learning model based on Long Short-Term Memory (LSTM) neural networks to produce a daily LST dataset for the Great Lakes that spans an unparalleled 42 years (1979–2020) at …

Molecular Dynamics Simulation Of Interfacial Tension Of The Co2-Ch4-Water And H2-Ch4-Water Systems At The Temperature Of 300 K And 323 K And Pressure Up To 70 Mpa, Quoc Truc Doan, Alireza Keshavarz, Caetano R. Miranda, Peter Behrenbruch, Stefan Iglauer

Research outputs 2022 to 2026

Subsurface geologic formations such as depleted hydrocarbon reservoirs, deep saline aquifers and shale formations have been considered promising targets for carbon dioxide and hydrogen storage. A solid understanding of the interfacial properties of multiphase systems, including binary (pure gas-water) and ternary (gas mixtures and water), is vital to assess for reliability and storage capacity of the geological formations. However, most previous experimental and simulation studies for interfacial properties have mainly focused on binary systems at low-medium pressure. Only a few experimental and simulation studies investigated the interfacial tension at high pressure (above 20 MPa) for the CO₂-CH_{4 …}

Bim And Digital Twins In Infrastructure Projects: An Overview From The Transportation Professional's Perspective, Natállia Mendes

LSU Master's Theses

Transport infrastructure has undergone significant changes in recent years due to the digitalization of construction methods. Consequently, there is an increasing demand for more productive and cost-effective technologies to optimize various aspects such as time, cost, changes, waste, and errors in projects. Notably, technologies such as Building Information Modeling (BIM) and Digital Twin (DT) hold the potential to enhance the performance of infrastructure projects. While BIM has received substantial attention in recent years, Digital Twin is relatively new to the construction industry. This leads to a scarcity of studies on DT and its integration with other emerging technologies like BIM. …

Geometry Through Architectural Design, Maureen T. Carroll, Elyn Rykken

LASER Journal

In her 1912 geometry book, Mabel Sykes surveys complex and beautiful architectural designs from around the world to inspire exercises on geometric proof, construction and computation. In over 1800 exercises, Sykes analyzes geometric patterns from ornamental and structural features found in tile mosaics, parquet floors, Gothic windows, trusses and arches. As Sykes' writes, ``Geometry gives, as no other subject can give, an appreciation of form as it exists in the material world" . We have chosen four examples to illustrate how her appealing designs and the accompanying exercises of this hidden gem can be incorporated into any geometry course.

Self-Adaptive Capacitor For Micro-Display Sub-Pixels, Qianqian Wang, Jacob Choi, Gang Chen

Defensive Publications Series

A display device has pixels that compensate a threshold voltage of a driving transistor through decreasing the discharge time of a capacitor coupled to the driving transistor. The capacitor may be embodied as a metal-oxide-semiconductor (MOS) transistor. The capacitor may include a non-uniform channel region having a capacitance that increases with a decrease of a gate-source voltage applied to the capacitor and decrease with an increase of the gate-source voltage applied to the capacitor.

Thermoresponsive Polymers With Lcst Transition: Synthesis, Characterization, And Their Impact On Biomedical Frontiers, Yichun Yuan, Konpal Raheja, Nathalie B. Milbrandt, Sophia Beilharz, Steffy Tene, Solomon Oshabaheebwa, Umut A. Gurkan, Anna Cristina S. Samia, Metin Karayilan

Faculty Scholarship

Advances in thermoresponsive materials have significantly impacted many biomedical fields. The unique behavior of reversible phase transition close to the physiological temperatures makes these types of materials a great candidate for a wide variety of biomedical applications including bioimaging, biosensing, injectables, smart surfaces, adhesives, biomanufacturing, and tissue engineering. Thermoresponsive behavior, mainly lower critical solution temperature (LCST) can be easily tuned by shifting the balance between hydrophobicity and hydrophilicity (e.g., by using comonomers or changing end groups) and modifying the molecular weight and architecture of the polymer. Hence, synthetic and characterization tools are critical in tailoring and precisely determining these properties. …

Topics In Absolute And Relative Treatment Effects In Medical Data Models And Applications With A Continuous Response, Sangit Regmi

Student Theses and Dissertations

Medical data models aim to evaluate the effectiveness of different treatments in a patient population, and to determine the relative and absolute treatment effects. The aim of this thesis is to evaluate the use of the traditional model when relative treatment effects exists and further develops a new model to account for both the absolute and relative treatment effects for a continuous response. The new model can be seen as a generalization of the traditional model by incorporating the relative treatment effect. It is shown in the simulation studies and real data set that the new model is able to …

Evaluating Frozen Soil Properties With Electrical Resistivity Measurement And Electro-Magnetic Induction Methods, Rui Liu

Theses and Dissertations

Electromagnetic induction was utilized in the past by the United States Army Corps of Engineers as a method of detecting unexploded ordinance, while it has the potential to act as a novel method of investigating frozen soils in cold regions. In this study, we performed lab-scale 1D electrical resistivity measurements under freeze-thaw circumstances on frost-susceptible soils with varied soil properties. We implemented an empirical model from our experiments into a COMSOL finite element model at both laboratory and field scales to simulate soil electrical resistivity response under both short-term and long-term sub-freezing conditions. Dynamic temperature-dependent soil properties, most notably unfrozen …

Bison Alter The Northern Yellowstone Ecosystem By Breaking Aspen Saplings, Luke E. Painter, Robert L. Beschta, William J. Ripple

Aspen Bibliography

The American bison (Bison bison) is a species that strongly interacts with its environment, yet the effects of this large herbivore on quaking aspen (Populus tremuloides) have received little study. We documented bison breaking the stems of aspen saplings (young aspen > 2 m tall and ≤ 5 cm in diameter at breast height) and examined the extent of this effect in northern Yellowstone National Park (YNP). Low densities of Rocky Mountain elk (Cervus canadensis) after about 2004 created conditions conducive for new aspen recruitment in YNP's northern ungulate winter range (northern range). We sampled …

School of Psychology

Objective Normal interictal [18F]FDG-PET can be predicted from the corresponding T1w MRI with Generative Adversarial Networks (GANs). A technique we call SIPCOM (Subtraction Interictal PET Co-registered to MRI) can then be used to compare epilepsy patients' predicted and clinical PET. We assessed the ability of SIPCOM to identify the Resection Zone (RZ) in patients with drug-resistant epilepsy (DRE) with reference to visual and statistical parametric mapping (SPM) analysis. Methods Patients with complete presurgical work-up and subsequent SEEG and cortectomy were included. RZ localisation, the reference region, was assigned to one of eighteen anatomical brain regions. SIPCOM was implemented using healthy …

Reading Images On The Wall: The Camera Obscura In The Academic Library, Stephanie Beene, Meggan Gould

University Libraries & Learning Sciences Faculty and Staff Publications

Creative practitioners spend much of their time outside of libraries, working in studios, labs, galleries, and other spaces. For this chapter, we declare that anyone can be a creative practitioner and that inspiration can come from new ways of experiencing the world. However, developing spaces to nurture creativity can be challenging within traditional academic library spaces. For example, if creativity is nurtured through experiential and embodied learning, how do we craft spaces within our libraries to inspire new modes of seeing, being, and knowing in the world? While librarians have long studied the information needs of artists, designers, and architects, …

Entry Receptor Ldlrad3 Is Required For Venezuelan Equine Encephalitis Virus Peripheral Infection And Neurotropism Leading To Pathogenesis In Mice, Natasha M Kafai, Hana Janova, Matthew D Cain, Yael Alippe, Stefanie Muraro, Alan Sariol, Michelle Elam-Noll, Robyn S Klein, Michael S Diamond

The Brown Foundation: Institute of Molecular Medicine

Venezuelan equine encephalitis virus (VEEV) is an encephalitic alphavirus responsible for epidemics of neurological disease across the Americas. Low-density lipoprotein receptor class A domain-containing 3 (LDLRAD3) is a recently reported entry receptor for VEEV. Here, using wild-type and Ldlrad3-deficient mice, we define a critical role for LDLRAD3 in controlling steps in VEEV infection, pathogenesis, and neurotropism. Our analysis shows that LDLRAD3 is required for efficient VEEV infection and pathogenesis prior to and after central nervous system invasion. Ldlrad3-deficient mice survive intranasal and intracranial VEEV inoculation and show reduced infection of neurons in different brain regions. As LDLRAD3 is a determinant …

Calculating The Difference In Stiffness Of Living T Cells Through Micropipette Aspiration, Minju Lee

McKelvey School of Engineering Graduate Student Theses & Dissertations

Cardiovascular disease (CVD) accounted for 17.9 million deaths in 2019, with fibrosis contributing to nearly a quarter of these fatalities [1,2]. Fibrosis, characterized by excessive connective tissue formation, has been strongly linked to T cells, essential components of the immune system. This study explores the mechanisms of T cell activation and the subsequent changes in biophysical properties like diameter, stiffness, and elasticity, aiming to develop therapeutic strategies for fibrosis-related diseases, including CVD. Utilizing the micropipette aspiration technique, we accurately assessed T cell stiffness and observed a change in bulk cell stiffness upon activation. The results demonstrated increased fluid-like behavior in …
