Ultra Low-Cycle Fatigue Behavior Comparison Between Additively Manufactured And Rolled 17-4 Ph (Aisi 630) Stainless Steels, David Gonzalez-Nino, Timothy Strasser, Gary S. Prinz Nov 2021

Ultra Low-Cycle Fatigue Behavior Comparison Between Additively Manufactured And Rolled 17-4 Ph (Aisi 630) Stainless Steels, David Gonzalez-Nino, Timothy Strasser, Gary S. Prinz

Civil Engineering Faculty Publications and Presentations

This study investigates the mechanical behavior of additively manufactured (AM) 17-4 PH (AISI 630) stainless steels and compares their behavior to traditionally produced wrought counterparts. The goal of this study is to understand the key parameters influencing AM 17-4 PH steel fatigue life under ULCF conditions and to develop simple predictive models for fatigue-life estimation in AM 17-4 steel components. In this study, both AM and traditionally produced (wrought) material samples are fatigue tested under fully reversed (R = −1) strain controlled (2–4% strain) loading and characterized using micro-hardness, x-ray diffraction, and fractography methods. Results indicate decreased fatigue life for …

The Primarily Undergraduate Nanomaterials Cooperative (PUNC) is an organization for research-active faculty studying nanomaterials at Primarily Undergraduate Institutions (PUIs), where undergraduate teaching and research go hand-in-hand. In this perspective, we outline the differences in maintaining an active research group at a PUI compared to an R1 institution. We also discuss the work of PUNC, which focuses on community building, instrument sharing, and facilitating new collaborations. Currently consisting of 37 members from across the United States, PUNC has created an online community consisting of its Web site (nanocooperative.org), a weekly online summer group meeting program for faculty and students, …


Experimental Heat Transfer Investigations Of A Double Pipe U-Tube Heat Exchanger Equipped With Twisted Tape And Cut Twisted Tape Internals, Raj Kumar Nayak Maloth, Glen Cletus Dsouza, Swarna Mayee Patra Nov 2021

Experimental Heat Transfer Investigations Of A Double Pipe U-Tube Heat Exchanger Equipped With Twisted Tape And Cut Twisted Tape Internals, Raj Kumar Nayak Maloth, Glen Cletus Dsouza, Swarna Mayee Patra

Mechanical and Materials Engineering Publications

For several decades, the use of heat exchangers for both heating and cooling applications has been established in industries ranging from process to space heating. Out of the various types of heat exchangers, U-tube heat exchangers are preferred owing to their abilities to handle larger flowrates and their simplicity in construction. U-tube exchangers are often equipped with innards of various forms which facilitate higher heat transfer rates and thermal efficiencies. Although higher heat transfer rates have been established with the addition of internals, there is a lack of coherence on the underlying complex physical phenomena such as heat transfer boundary …


Reliability Models For Smartphone Applications, Sonia Meskini, Ali Bou Nassif, Luiz Fernando Capretz Nov 2021

Reliability Models For Smartphone Applications, Sonia Meskini, Ali Bou Nassif, Luiz Fernando Capretz

Electrical and Computer Engineering Publications

Smartphones have become the most used electronic devices. They carry out most of the functionalities of desktops, offering various useful applications that suit the user’s needs. Therefore, instead of the operator, the user has been the main controller of the device and its applications, therefore its reliability has become an emergent requirement. As a first step, based on collected smartphone applications failure data, we investigated and evaluated the efficacy of Software Reliability Growth Models (SRGMs) when applied to these smartphone data in order to check whether they achieve the same accuracy as in the desktop/laptop area. None of the selected …


Polar Ice As An Unconventional Water Resource: Opportunities And Challenges, Zahra Karimidastenaei, Björn Klöve, Mojtaba Sadegh, Ali Torabi Haghighi Nov 2021

Polar Ice As An Unconventional Water Resource: Opportunities And Challenges, Zahra Karimidastenaei, Björn Klöve, Mojtaba Sadegh, Ali Torabi Haghighi

Civil Engineering Faculty Publications and Presentations

Global water resources are under pressure due to increasing population and diminishing conventional water resources caused by global warming. Water scarcity is a daunting global problem which has prompted efforts to find unconventional resources as an appealing substitute for conventional water, particularly in arid and semiarid regions. Ice is one such unconventional water resource, which is available mainly in the Arctic and Antarctic. In this study, opportunities and challenges in iceberg utilization as a source of freshwater were investigated on the basis of a systematic literature review (SLR). A search in three databases (Scopus, Web of Science, and ProQuest) yielded …


Correlations Between Mechanical And Index Properties Of Sandstone From The Central Salt Range, M. Z. Emad, M. U. Khan, S. A. Saki, M. A. Raza, M. U. Tahir Nov 2021

Correlations Between Mechanical And Index Properties Of Sandstone From The Central Salt Range, M. Z. Emad, M. U. Khan, S. A. Saki, M. A. Raza, M. U. Tahir

Mining Engineering Faculty Research & Creative Works

Abstract: A study was conducted to uncover the possible correlations among mechanical and index properties of sandstones from formations of Salt Range area, Punjab, Pakistan. For this purpose, sandstone block samples were collected from seven formations of the Salt Range. The samples were prepared for rock testing according to the guidelines set by International Society of Rock Mechanics (ISRM). Defective samples were discarded and those meeting the ISRM specifications were tested for sonic velocities, dry density, porosity, uniaxial compressive strength, tensile strength and elastic constants. Results obtained were then statistically analyzed to find the predictive relationships. The analysis revealed that …


Protection Of Patient Privacy On Mobile Device Machine Learning, Matthew Nguyen Nov 2021

Protection Of Patient Privacy On Mobile Device Machine Learning, Matthew Nguyen

Cybersecurity Undergraduate Research Showcase

An existing StudentLife Study mobile dataset was evaluated and organized to be applied to different machine learning methods. Different variables like user activity, exercise, sleep, study space, social, and stress levels are optimized to train a model that could predict user stress level. The different machine learning methods would test if both patient data privacy and training efficiency can be ensured.
