Structural Vibration Damping By The Use Of Poro-Elastic Layers: A Summary, Yutong Xue, J Stuart Bolton

Publications of the Ray W. Herrick Laboratories

A properly designed limp porous materials such as fibrous layers can provide damping equivalent to conventional viscoelastic dampers while providing advantages such as light weight and effective sound absorption. This then allows porous layers to be used as multi-functional noise and vibration control solutions in automotive and aerospace applications. Further, the addition of bulk elasticity to the solid phase of the porous medium is beneficial since it improves damping performance compared to equivalent limp treatments. In the work summarized here, porous media, such as fibers and foams, were designed to serve as treatments for various vibrating structures to examine their …

Department of Chemistry Faculty Publications

Nonaqueous dispersions of graphene nanoplatelets (GrNPs) can be used to prepare thin films and coatings free of surfactants, but typically involve polar organic solvents with high boiling points and low exposure limits. Here, we describe the mechanochemical exfoliation and dispersion of GrNPs in volatile aprotic solvents such as ethyl acetate (EtOAc) and acetone, which rank favorably in green solvent selection guides. GrNPs in powder form were exfoliated with a solvent on a horizontal ball mill for 48 h and then sonicated at moderate power to produce suspensions in excess of 300 μg/mL with minimum loss of dispersion stability over 7 …

Using Behavior Sequence Analysis To Study Teams During Long- Duration Isolation And Confinement, Andres Käosaar, Dr. Nathan Smith, Dr. David A. Keatley, Pranav Ambhorkar, Dr. Moritz Von Looz, Konstantinos Konstantinidis

Journal of Human Performance in Extreme Environments

With a renewed impetus and appetite for human space exploration, both government-funded agencies and private companies are focusing on longer and farther crewed missions into the solar system. Such space missions rely on highly interdependent teams living and working together in isolated, confined, and extreme (ICE) environments. Understanding the behavioral patterns of teams in ICE environments is, thus, paramount for the future success of such missions. Due to the complexity of studying ICE teams, several researchers have called for methodological innovations to advance knowledge in this area. In the current research, a proof-of-concept methodological approach is introduced that provides a …

This pre-registered study uses a field experiment to evaluate legislator responsiveness to policy entrepreneur outreach. In partnership with a leading AI think tank, we send more than 7300 U.S. state legislative offices emails about AI policy containing an influence strategy (providing a narrative, expert information, or the organization's background), along with a prominent issue frame about AI (emphasizing technological competition or ethical implications). To assess engagement, we measure link clicks to further resources and webinar …

The Role Of Region And Religious Tradition In Predicting Individuals’ Expressions Of Faith In The Workplace, Jacqui Frost, Christopher P. Scheitle, Elaine Howard Ecklund, Denise Daniels

Purdue University Libraries Open Access Publishing Fund

While many variables might influence an individual’s willingness to express their faith in the workplace, the role of regional context has not been fully considered. The different geographical regions in the U.S. consist of unique demographics and cultures that could shape an individual’s expression of faith at work. Moreover, these regional effects might be moderated by an individual’s specific religious tradition. Using data from a survey of U.S. adults featuring oversamples of Jewish and Muslim individuals, we utilize two unique measures of religious expression—displaying/wearing religious items at work and talking about religion at work—to assess the roles of region and …

When Those With Privacy Concerns Show Stronger In-Group Favoritism: Using Personal Information From In-Group And Out-Group Members To Identify Terrorist Threats, Torsten Reimer, Nathanael Johnson

Purdue University Libraries Open Access Publishing Fund

Terrorist threats and attacks provide major risks and sources of public crises in the 21st century. New probabilistic computing technologies possess the capability of increasing the success of identifying terrorist threats and solving cybersecurity and encryption problems more efficiently. However, to identify terrorist threats, these technologies would require the use of a large amount of personal data, which cause potential concerns for privacy. We offer a social-identity explanation of public support for the detection of terrorist threats through the use of online personal data. A survey study (N = 1,204) revealed strong support for the provided social-identity explanation of …

Rapid And Efficient Computation Of Cell Trajectories During Ultrasonic Focusing, Charles F. Babbs, Mary V. Lang

Weldon School of Biomedical Engineering Faculty Working Papers

This biophysical analysis explores the first-principles physics of movement of white blood cell sized particles, suspended in an aqueous fluid and experiencing progressive or standing waves of acoustic pressure. In many current applications the cells are gradually nudged or herded toward the antinodes of the standing wave, providing a degree of acoustic focusing and concentration of the cells in layers perpendicular to the direction of sound propagation. Here the underlying biomechanics of this phenomenon are analyzed specifically for the viscous regime of water--as opposed to air--and for small diameter microscopic spheroids such as living cells--as opposed to large diameter, macroscopic …

Secondly, we specify the different public intervention measures implemented by national, regional, and local authorities in Spain. Finally, we set out the …

Destinations’ Recovery Marketing Campaigns In Response To Pandemics, Eli Avraham

ITSA 2022 Gran Canaria - 9th Biennial Conference: Corporate Entrepreneurship and Global Tourism Strategies After Covid 19

The Covid-19 pandemic has altered the paradigm of risk and recovery management but it is just one of many pandemics to have impacted destinations during the last two decades. This study examine how destination officials combated the image crises that followed SARS-2003, H1N1 Swine flu 2009-10, Zika 2016-17 and Covid-19. The literature dealing with combating pandemics has focused on the actual management of either a specific pandemic or regional aspects of a pandemic and less on the recovery marketing and image repair aspect. As a result, tourism academic literature has a shortage of image repair theoretical frameworks addressing multi-case health-related …

People and Animals: The International Journal of Research and Practice

The impacts of companion animals on human well-being have been receiving increased media and research attention, especially in relation to the COVID-19 pandemic. Previously, there have been calls for research to consider the major components of subjective well-being separately and for research designs to include assessments over time. In line with this suggestion, the purpose of this study was to gain a more comprehensive understanding of how being a dog guardian can impact affect and contribute to the overall assessment of subjective well-being. This study used a seven-day diary design to capture 31 dog guardians’ day-to- day feelings and thoughts …

Optically Induced Electrothermal Microfluidic Tweezers In Bio-Relevant Media, Kshitiz Gupta, Hye-Ran Moon, Zhengwei Chen, Bumsoo Han, Nicolas G. Green, Steven T. Wereley

Purdue University Libraries Open Access Publishing Fund

Non-contact micro-manipulation tools have enabled invasion-free studies of fragile synthetic particles and biological cells. Rapid electrokinetic patterning (REP) traps target particles/cells, suspended in an electrolyte, on an electrode surface. This entrapment is electrokinetic in nature and thus depends strongly on the suspension medium’s properties. REP has been well characterized for manipulating synthetic particles suspended in low concentration salt solutions (~ 2 mS/m). However, it is not studied as extensively for manipulating biological cells, which introduces an additional level of complexity due to their limited viability in hypotonic media. In this work, we discuss challenges posed by isotonic electrolytes and suggest …

Double Reservoirs Imaged Below Great Sitkin Volcano, Alaska, Explain The Migration Of Volcanic Seismicity, Xiaotao Yang, Diana C. Roman, Matthew Haney, Cody A. Kupres

Purdue University Libraries Open Access Publishing Fund

Volcanic seismicity provides essential insights into the behavior of an active volcano across multiple time scales. However, to understand how magma moves as the eruption cycle develops, better knowledge of the geometry and physical properties of the magma plumbing system is required. In this study, using full-wave ambient noise tomography, we image the three-dimensional (3-D) crustal shear-wave velocity structure below Great Sitkin Volcano in the central Aleutian Arc. The velocity model reveals two low-velocity anomalies correlating with the migration of volcanic seismicity. With a bulk melt fraction of about 2.5%–9%, these low-velocity anomalies are interpreted as mushy magma reservoirs. We …

The Adoption And Use Of Smart Assistants In Residential Homes: The Matching Hypothesis, Nathanael Johnson, Torsten Reimer

Purdue University Libraries Open Access Publishing Fund

An increasing number of residential homes are equipped with smart assistants such as Cortana, Alexa, and Siri. Adoption rates and the frequency of the usage of smart assistants vary across users and residential homes. Building on the theory of uses and gratifications (UGT) and the unified theory of acceptance and use of technology 2 (UTAUT2), the objective of this paper was to examine whether the intended use of a digital assistant would moderate the effects of performance expectancy and hedonic motivation on its adoption. Two experiments (N = 345 and N = 351) tested the hypothesis that, for utilitarian purposes, …
