Presenter: Chris Carroll, Ph.D., E.I. Assistant Professor, Department of Civil Engineering, University of Louisiana at Lafayette (hosted by Dr. Devin Harris) 

TOPIC: Sustainability from the Perspective of an Ancient Engineer

BIO: Dr. Carroll received his Ph.D. from Virginia Tech in August of 2009 and has been an assistant professor at the University of Louisiana at Lafayette since.  Dr. Carroll’s research focus is primarily in the areas of prestressed and reinforced concrete with a concentration on the bond between concrete and reinforcing steel.  He is an active member of the American Concrete Institute and American Society of Civil Engineers.  In addition to his experimental interests, he also has an interest in engineering education, specifically those related to active and visual teaching techniques and project and problem based learning used in structural engineering courses.  Furthermore, Dr. Carroll has also hosted three television shows in conjunction with the History Channel and Discovery Channel as a technical expert.  Most recently, he served as co-host on a pilot series entitled Engineering the Impossible for the Discovery Channel.  The pilot series included two shows focused on the engineering techniques used by the Ancient Engineers of Rome and Egypt.  Dr. Carroll along with a group of his students recreated various structures from the ancient Roman and Egyptian Empires showcasing some of the techniques believed to be used by each to construct some of the most famous structures in the world.

ABSTRACT: For centuries, the Coliseum, Pantheon, and aqueducts have been admired time and time again.  Their sheer size alone is awe inspiring and constantly raises the question, “How were they built?”  While hypotheses exist for their construction, maybe the more important question is “How have they withstood the test of time?”  In a day and age where sustainability is a key concern in new designs, looking at the work of ancient engineers could reiterate what sustainability is and to what areas structural engineers should devote their attention.  This presentation highlights the methods used by the Romans in the construction of the Coliseum, Pantheon, and Pont du Gard Aqueduct and touches on some key principles related to their continued survival.

S-STEM Seminar April 4: Kaira Wagoner, Potters for Peace

Speaker: Ms. Kaira Wagoner
Title of presentation: Ceramic Weapons of Mass (Bacterial) Destruction; A Simple, Affordable and Effect Solution to Waterborne Disease
Time: 3-4 pm Wednesday April 4th
Place: 642 DESEB

Bio:
Kaira Wagoner is currently a Environmental Health Sciences PhD student at the University of North Carolina, Greensboro. After graduating from Guilford College in 2006, Kaira and her partner Reynaldo Diaz were trained in ceramic filter production by the late Ron Rivera, former Filter Coordinator of Potters for Peace. Since 2008, Kaira has assumed the position of Filter Communication Coordinator for Potters for Peace, and has conducted filter work in Tanzania, Somaliland, Rwanda, Uganda, Zimbabwe, Mozambique, and Kenya.

Potters for Peace:
Potters for Peace is a U.S. based nonprofit network of potters, educators, technicians, supporters, and volunteers. Founded in Nicaragua in 1986, we work with clay artisans in Central America and worldwide on ceramic water purification projects. Every day 5,000 children die due to unsanitary water (WHO 2005). Since 1998 Potters for Peace has traveled the world teaching the fabrication of a low-cost ceramic water filter that can bring clean, potable water to those who need it most. We do not make, store or distribute ceramic water filters nor do we operate filter production facilities. Instead, we assist responsible local partners to set up filter production and distribution facilities.

Topic: Climate Informed Flood Risk Projections
Presenter: Casey Fritsch, Master student, Department of Civil and Environmental Engineering, (Adviser: Dr. Veronica Griffis)

Abstract: Standard procedures for forecasting flood risk (Bulletin 17B) assume annual maximum flood (AMF) series are stationary, meaning the distribution of flood flows is not significantly affected by climatic trends/cycles, or anthropogenic activities within the watershed. Historical flood events are therefore considered representative of future flood occurrences, and the risk associated with a given flood magnitude is modeled as constant over time. However, in light of increasing evidence to the contrary, this assumption should be reconsidered, especially as the existence of nonstationarity in AMF series can have significant impacts on planning and management of water resources and relevant infrastructure. Research presented in this thesis quantifies the degree of nonstationarity evident in AMF series for unimpaired watersheds throughout the contiguous U.S., identifies meteorological, climatic, and anthropogenic causes of this nonstationarity, and proposes an extension of the Bulletin 17B methodology which yields forecasts of flood risk that reflect climatic influences on flood magnitude.

Topic: Domain Microstructure Evolution and Magnetomechanical Property of Giant Magnetostrictive Materials

Presenter: Dr. Yongmei M. Jin, Assistant Professor, Materials Science and Engineering Department, Michigan Technological University

Bio: Dr. Jin received B.E. and M.E. in Mechanical Engineering from University of Science and Technology of China in 1994 and 1997, respectively, and Ph.D. in Materials Science and Engineering from Rutgers University in 2003. After two years of postdoctoral research at Rutgers University, she joined the Department of Aerospace Engineering at Texas A&M University in 2005 as an Assistant Professor and transferred to the Department of Materials Science and Engineering at Michigan Tech in 2009. Her research interest focuses on materials modeling and computer simulation. In particular, she has been working on the development and application of phase field models to investigate microstructure evolutions in crystalline materials during various physical processes, e.g., martensitic transformation, decomposition, ordering, ferromagnetic domain switching, magnetomechanical behaviors, and defect evolutions (dislocations, cracks, voids, and free surfaces) in single- and poly-crystalline bulk and thin film materials and nanoparticles.

Abstract: Domain microstructure evolution and magnetomechanical property of giant magnetostrictive materials are investigated by phase field micromagnetic microelastic modeling. The model explicitly treats magnetic and elastic domain microstructures, accurately calculates various thermodynamic driving forces (magnetostatic, elastostatic, magnetocrystalline, exchange, chemical, interfacial, applied magnetic field, mechanical loading), simultaneously takes into account multiple physical mechanisms, and automatically describes the domain microstructure evolutions along kinetically favorable pathways without a priori constraint. In particular, coupled magnetic and elastic domain microstructure evolutions in magnetic shape memory alloys are simulated. The simulation results reveal the effects of external magnetic field, twin boundary mobility, and twinning strain on domain structure evolutions, which help explain peculiar magnetic field-induced strain behaviors observed in magnetic shape memory alloys. Application of phase-field modeling to the microstructure evolutions in other material processes are also discussed. Connections between mesoscale phase-field modeling, atomistic (first principles, molecular dynamics) and continuum (finite element) simulations, thermodynamic and kinetic databases as well as experiments are addressed.

Topic: Railroads and Environment – Steps in Locomotive and Power Development to Improve the Environmental Footprint of Rail Transportation

Presenter: Mike Iden – General Director, Car and Locomotive Engineering, Union Pacific Railroad
(hosted by Pasi Lautala)

Abstract: Railroads and rail transportation is often considered the “green” transportation alternative, but there is never-ending development process toward improving both the energy efficiency and the environmental footprint of rail transportation. One of the greatest priorities has been locomotives, whether it has been in reducing emissions or in improving operational practices toward better fuel consumption. This presentation will review some of the latest and future advances related to the development of north American diesel locomotives that today dominate the market. The difference between on-board power (diesel-electric or other prime movers) versus centralized power (“electrification”) will also be discussed, including technical and economic issues.

Topics:

1. Integration of Mainshock-Aftershock Sequences Into Performance-Based Engineering
Presenter: Ruiqiang Song, Ph.D. Student, Department of Civil and Environmental Engineering, (Adviser: Dr. Yue Li)

Abstract: During earthquake events, it is very common to observe many aftershocks following the mainshock. Although they are normally smaller in magnitude, aftershocks may have a large ground motion intensity, even longer duration and different energy content. Aftershocks have the potential to cause severe damage to buildings and threaten life safety even when only minor damage is present from the mainshock. However, most of current seismic risk assessment researches focus on risk due to a mainshock event only. The primary goal of this research is to systematically integrate aftershock seismic hazard into Performance Based Engineering through a combination of analytical studies with structural degradation models. In this study, the global-level hysteresis damage models is calibrated, structural Collapse Capacity subjected to Mainshock and aftershock sequence is carried out by performing incremental dynamic analysis, the effect of frequency content on structural collapse capacity are also checked and ground motion attenuation relationship of response spectral values are presented.

2. Building Information Modeling: A Demonstration of Parametric Modeling and its Use in the Construction Industry
Presenter: Christopher Brokaw, Master student, Department of Civil and Environmental Engineering, (Adviser: Dr. Amlan Mukherjee)

Abstract: Building information modeling (BIM) is a type of software that can be used to create a 3D model of a construction project that integrates information about the materials and scheduling. This makes it is possible to quickly explore multiple alternate designs and evaluate their performance, as well as plan out the entire project and management strategies. This allows for improved information management and project control when compared to projects designed with 2D drafting software. In this presentation, I will use a hands-on demonstration to explore BIM software and illustrate how stakeholders can use this software to streamline the design process, reduce conflicts, and save money. I will also present an overview of my ongoing research project that, in addition to the above, will explore the benefits of transitioning to BIM software, and will show some of the lessons learned from the early adopters.
