Grain Boundary Induced Deformation Mechanisms In Nanocrystalline Al By Molecular Dynamics Simulation: From Interatomic Potential Perspective, Liang Zhang, Yasushi Shibuta, Xiaoxu Huang, Cheng Lu, Mao Liu

Faculty of Engineering and Information Sciences - Papers: Part B

Nanocrystalline metals exhibit many excellent mechanical properties and their underlying deformation mechanisms have been studying widespread. The well-designed atomistic simulations can predict the mechanical behavior of materials ahead of experiments and provide sufficient information on the atomic scale. The choice of appropriate interatomic potential is one of the main concerns of any atomistic simulation that needs to be seriously considered in order to obtain reliable results. In this study, we investigated the mechanical response and the deformation mechanisms of nanocrystalline Al under uniaxial loading by molecular dynamics (MD) simulations with different embedded atom method (EAM) interatomic potentials. The selection of ...

A New Method For Direct Tensile Testing Of Concrete, Faez Alhussainy, Hayder Alaa Hasan, M Neaz Sheikh, Muhammad N. S Hadi

Faculty of Engineering and Information Sciences - Papers: Part B

Different testing methods were used in previous studies to measure the direct tensile strength of concrete. However, these methods experienced several major deficiencies such as stress concentration at the end of the specimens because of inadequate gripping and loading eccentricity and nonuniform fracture plane because of difficulties in aligning and centering the specimens during testing. This study presents the details of a new method of testing concrete under uniaxial tension. The method was developed to overcome the difficulties associated with testing methods adopted in the previous research studies. A full description of the wooden molds used in casting the specimens ...

Economic Potential For Distributed Manufacturing Of Adaptive Aids For Arthritis Patients N The U.S., Nicole Gallup, Jennifer Bow, Joshua M. Pearce

Department of Materials Science and Engineering Publications

By 2040, more than a quarter of the U.S. population will have diagnosed arthritic conditions. Adults with arthritis and other rheumatic conditions earn less than average yet have medical care expenditures that are over 12% of average household income. Adaptive aids can help arthritis patients continue to maintain independence and quality of life; however, their high costs limit accessibility for older people and the poor. One method used for consumer price reduction is distributed manufacturing with 3-D printers. In order to assess if such a method would be financially beneficial, this study evaluates the techno-economic viability of distributed manufacturing ...

Research Incentive Programs For Closures Of Public And Private Grade Crossings, Julius Codjoe

Publications

Vehicle-train crashes that occur at highway-rail crossings result in injuries, fatalities, and damage to equipment. In order to reduce the number of vehicle-train crashes, Federal Railroad Administration requires states which have challenges with crossing safety, including Louisiana, to develop a State Action Plan to improve grade crossing safety. Consequently, identification of specific solutions for improving safety at crossings was included in the 2015 Louisiana Transportation Plan as one of its objectives. This study seeks to identify and evaluate current and new incentive programs that encourage closure of at-grade railroad crossings to reduce the number of potential vehicle-train collision points, and ...

Recruiting, Retaining, And Promoting For Careers At Transportation Agencies, Christofer Harper, Susan Bogus, Raghava Kommalapati, Doeun Choe

Publications

State transportation agencies currently face complex challenges in recruiting and retaining the workforce necessary to function effectively. The situation exacerbates due to the number of employees from different generations that have to coexist with varying values, expectations, and principles. These agencies are primarily comprised of two generational groups: the baby-boomers, who are approaching retirement and occupy many managerial positions; and the millennials, who are demonstrating their interest in technology and demanding dynamism in their careers. This multiplicity of interest represents a challenge for human resources (HR) in addressing workforce issues and providing the necessary means to recruit and retain qualified ...


Young’S Modulus As A Measurement To Estimate Damage Related With Alkali-Silica Reaction In Concrete., Anazaria J. Ortega Gonzalez Dec 2018

Young’S Modulus As A Measurement To Estimate Damage Related With Alkali-Silica Reaction In Concrete., Anazaria J. Ortega Gonzalez

Civil Engineering Undergraduate Honors Theses

The main purpose of this research is to compare two nondestructive methods to assess Alkali-Silica reaction (ASR) in concrete. Fifteen concrete prisms were cast using aggregates with different Alkali-Silica reactivity such as Jobe sand and Van Buren sand. The change in strain, shear wave velocity and Young’s modulus were determined according to ASTM C129 and ASTM C215, respectively. This data was collected by Dillon K Self, who determined that the shear wave velocity and strain are inversely proportional. However, when single cracking in the concrete specimen transition to map cracking, the shear wave velocity dropped significantly, whereas the strain ...


The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership, Edgar Bertini Ruas Nov 2018

The Influence Of Shared Mobility And Transportation Policies On Vehicle Ownership, Edgar Bertini Ruas

TREC Friday Seminar Series

With the emergence of several new providers of shared mobility services, such as Uber, Biketown and Car2go, there has been the promise of changes to the traditional way of owning and using a vehicle. One potential consequence of the new mobility services is the reduction in vehicle ownership. At the same time, cities are trying to anticipate these changes by reducing the amount of space dedicated to parking. This thesis aims to asses the extent to which new shared mobility and transportation policy strategies (especially parking requirements and transit pass availability) relate to vehicle ownership among residents of multifamily dwellings ...

The Relationship Between Teamwork Knowledge And Teamwork Behavior, Jeeun Yi, Glenn E. Littlepage Oct 2018

The Relationship Between Teamwork Knowledge And Teamwork Behavior, Jeeun Yi, Glenn E. Littlepage

River Cities Industrial and Organizational Psychology Conference

Many organizations utilize a team-focused work structure in the workplace. Researchers have studied how working as a team can improve organizational outcomes such as productivity and employee satisfaction (Katzenbach & Smith, 1993). However, not all teams make positive outcomes (Hackman, 1998). Previous research has shown that effective teamwork can facilitate group and organizational effectiveness (Salas, Stagl, Burke, & Goodwin, 2007). Various models of teamwork process have been developed (Marks, Mathieu, & Zaccaro, 2001; Rousseau, Aube, & Savoie, 2006; Salas, Sims, & Burke, 2005). A meta-analysis found a consistent relationship between the ten dimensions of teamwork identified by Marks et al. (2001) and team performance (LePine, Piccolo, Jackson, Mathieu, & Saul, 2008). Previous research has shown that team members with high cognitive ability, certain personality characteristics, and job-related knowledge and skills may contribute to better performance (Devine & Philips, 2001; Mathieu & Schulze, 2006; Morgeson, Reider, & Campion, 2005; Neuman & Wright, 1999). Among those characteristics, having aggregate member knowledge of teamwork showed a positive relationship with team performance (McClough & Rogelberg, 2003), but the relationship between individual teamwork knowledge and individual teamwork behaviors has not been widely examined. In this study, the relationship between teamwork knowledge and teamwork behavior will be examined. Building on the main relationship, this study will also investigate the impact ...

Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri Oct 2018

Webinar: Addressing Bicycle-Vehicle Conflicts With Alternate Signal Control Strategies, Sirisha Kothuri

TREC Webinar Series

There is nationwide interest in supporting sustainable and active transportation modes such as bicycling and walking due to the many benefits associated with them, including reduced congestion, lower emissions and improved health. Although the number of bicyclists is increasing, safety remains a top concern. In urban areas, a common crash type involving bicycles at intersections is the “right hook” where a right-turning vehicle collides with a through bicyclist. While geometric treatments and pavement markings have been studied, there is a lack of research on signal timing treatments to address right-hook bicycle-vehicle conflicts.

Supporting Shrinkage: Better Planning And Decision-Making For Legacy Cities, Michael P. Johnson Jr., Justin B. Hollander, Eliza Davenport Whiteman Oct 2018

Supporting Shrinkage: Better Planning And Decision-Making For Legacy Cities, Michael P. Johnson Jr., Justin B. Hollander, Eliza Davenport Whiteman

Michael P. Johnson

Planning and policy design for shrinking and distressed regions is challenging. Traditionally, planners use
a variety of tools and incentives to encourage land uses that accommodate changes in populations,
infrastructure and activities to maximize quality of life and social and environmental sustainability.
These are generally designed for growing cities and politically and socially active communities. Since
many regions face significant disparities in social supports, financial resources and quality of life, use of
these tools is thus problematic.

Information technology and the Internet have transformed the production of goods and services. The
‘big data’, ‘smart cities’ and ‘e-government’ movements make it ...
