The need to meet rising energy demands while mitigating climate change driven by associated CO2 emissions has motivated the development of geologic carbon storage systems. Until recently, most research focused on sedimentary reservoirs that rely primarily on short-term solubility and physical trapping mechanisms, where CO2 can migrate if structural security is compromised. This inherent leakage risk could be eliminated by leveraging the natural reactivity of basalt reservoirs, which are abundant in silicate minerals that dissolve rapidly under acidic conditions and can ultimately trap dissolved CO2 as solid carbonate minerals. However, our fundamental understanding of the conditions under which CO2 mineralization occurs and its viability as a permanent carbon sequestration pathway remain limited. This talk will highlight series of high-pressure core flooding experiments and complementary reactive transport modeling designed to evaluate the effects of temperature, fluid chemistry, and transport regimes on basalt dissolution and carbonate precipitation. Results indicate that basalts can effectively mineralize CO2 at representative subsurface stress conditions, but predominantly within buffered diffusion-limited zones (e.g. dead-end fractures) where reaction fronts developed from competing geochemical gradients. Carbonate precipitation was highly localized on reactive silicate minerals contributing key divalent cations and was significantly enhanced by elevated temperature and alkalinity. In combination, this work reveals how complex interactions between reservoir geochemistry and transport conditions drive the extent and spatial distribution of carbon mineralization reactions in basalt fractures, which will inform selection of storage sites and injection.

Ultra-high performance concrete (UHPC) is an advanced cement-based, fiber-reinforced composite material that is emerging as a popular solution to many challenges related to highway bridge performance and durability. UHPC-class materials exhibit mechanical and durability properties that far exceed those of both conventional and high-performance concretes. The Structural Concrete Group at FHWA’s Turner-Fairbank Highway Research Center (TFHRC) has been conducting research on UHPC-class materials for more than 15 years, and has played a significant role in the growing popularity of this innovative class of materials in the US bridge market.
The objective of this presentation is to introduce the state-of-practice for UHPC in US highway bridge market, and discuss how this material is innovating the way we design and construct highway bridges. The presentation will include: a review of the basic properties of UHPC-class materials; a discussion of the current deployments in the US bridge market; and a discussion of recent research conducted at TFHRC. Research topics to be discussed will include: prefabricated bridge element connections using UHPC; UHPC for bridge repair and rehabilitation; and recent research focused on understanding the fundamental material properties and structural response of UHPC-class materials.

Lateral circulation and its role in disrupting the classical pattern of intra-tidal stratification in estuaries (February 5, 2020 12:00pm) https://events.umich.edu/event/70028 70028-17499522@events.umich.edu Event Begins: Wednesday, February 5, 2020 12:00pm
Location: GG Brown Laboratory
Organized By: Civil and Environmental Engineering

The tidal cycle variability of stratification in an estuary is controlled by the interaction between tidal flows, bathymetry, and the estuary's longitudinal salt gradient. Two-dimensional analysis (in the vertical-longitudinal plane) of a straight, estuarine channel yields the classical theory of periodic stratification from tidal straining, and this mechanism typically works to enhance stratification on ebb tides and break it down through active mixing on flood tides. Ecological implications of mixing relative to tidal phase include whether sediment can reach perimeter habitats high in the tidal prism, whether phytoplankton reach sunlight, and whether hypoxia at depth persists longer than biology can tolerate. This pattern of stratification can be disrupted by density-driven exchange with shallow regions lining the channel: differential advection over channel-shoal bathymetry sets up lateral gradients in velocity, straining the salinity field and driving an input of fresher water at the surface of the channel during flood tides. Here, we present analytical scaling groups to weigh the contributions of longitudinal and lateral tidal straining and explore the conditions which lead to flood-tide stratification through this lateral exchange mechanism. Idealized, fully three-dimensional model results from the Regional Ocean Modeling System (ROMS) are used to explore the parameter space described by the scaling groups.

A Data-Driven Optimization Approach For the Dynamic Shuttle Dispatching Problem (February 6, 2020 2:30pm) https://events.umich.edu/event/70040 70040-17499534@events.umich.edu Event Begins: Thursday, February 6, 2020 2:30pm

The problem of dispatching shuttles to serve trip requests can be mathematically formulated as a dial-a-ride problem (DARP). With on-demand mobility services gaining more popularity in recent years, the real-time application of DARP is attracting ever more interest. However, the fact that size of DARP grows exponentially with number of requests renders the current solution methodologies inadequate for online applications. In order to tackle this issue, we propose a general framework that shifts much of the computational burden of the optimization problems that need to be solved into an offline setting, thereby addressing on-demand requests with fast and high-quality solutions in real time. Furthermore, in order to improve the utilization rate of vehicles, we seek to dispatch our shuttle proactively, and not wait for the demand to be realized first. Using various numerical experiments, we demonstrate the benefits of the proposed method. Furthermore, we present a sensitivity analysis to show the performance of our methodology under different parameter settings.

Water infrastructure renewal is receiving significant attention today as many of our systems are meeting (or exceeding) design life. Cities in countries with well developed economies like the U.S. enjoy economic prosperity in part due to the development of heavily centralized water systems that create high levels of water quality and public health, on average. While centralized water infrastructure has served us well, I argue that we should not be constrained to applying 20th century thinking as we plan for the future. The current revolution in information technologies (IT: software, hardware and devices) has the potential to transform urban water infrastructure by creating more resilient and flexible hybrid systems comprised of an interacting collection of centralized and decentralized physical IT systems. I contend that the development of IT-enabled “smart” hybrid water system solutions has the potential to: improve the efficiency with which we use resources (e.g., water, power,
nutrients); enhance equitable access to water services; change consumer and provider behavior around water; and ensure that we sustain a high level of public health, even as more people live in close proximity to each other. In this talk and through the use of case studies from across different regions around the globe, I will explore these scenarios and the changing ways in which people live. As an example, one case study will include the development of “smart” distributed nutrient recovery systems that have been deployed and are being tested at the University of Michigan.

Autonomous vehicles (AVs) are expected to improve mobility, safety, and parking accessibility. It is estimated that AVs will be available on the market in the next decade. As car-parks are closed environments, they are among the first locations to expect influenced by AVs. AVs can be stacked in multiple rows like valet parking due to their self-parking capability. To release blocked vehicles, car-park operators relocate certain vehicles in driverless mode to create a clear pathway for cars that need to leave the facility. The problem of finding the optimal car-park layout design is investigated that minimizes relocations to fit a given number of vehicles. Results show that AV parking facilities can decrease the need for parking space by an average of 62%. The operation of AV parking facilities is also investigated, and policies for choosing a parking spot for each vehicle are proposed based on the arrival and departure time information. AVs will not only change the car-park facilities, but also where travelers park. AV users can exit from their vehicles and send their vehicles to park in a strategic location. AVs can park farther from destination in cheaper parking lots or cruise for the whole activity time. Results show that while the same parking price across all the locations would exacerbate the congestion by motivating more AVs to cruise, a toll for zero- occupant AVs would decrease the congestion.

Sina Bahrami is a Postdoctoral fellow at University of Michigan. He received a B.S. and an M.S. in Civil Engineering from Sharif University of Technology, and a Ph.D. from University of Toronto. Sina’s research is focused on the parking policy in the era of Avs.

The design of structures to protect occupants and operations in response to man-made extraordinary events requires attention to critical failure mechanisms and component behavior. Since the intensity and likelihood of these events are not well defined, performance based design approaches include the management of inelastic response and local failure. Design techniques that were developed for the ‘cold war’ are now adapted for Government and commercial construction. Applying these techniques to ‘design excellence’ architecture is a major challenge and the least impactful protective measures that achieve the required performance contribute to a project’s success. In many projects, the protective design engineer helps identify the risks associated with different design options and helps the owners to decide whether to mitigate or accept these risks.

In this talk, we consider the design of car-sharing services for a major car-sharing service providor. The problem is formulated as a high-dimensional discrete simulation-based optimization (DSO) problem. We propose a method that combines disaggregate car-sharing reservation data, analytical mathematical programming (MP) models, and simulation-based optimization algorithms. We present various ways in which the MP formulations can be used to enhance both the computational efficiency of DSO algorithms, as well as their ability to tackle high-dimensional problems. We present numerical results on a Boston case study.

Adaptive Testing Scenario Library Generation for CAV Evaluation Based on Bayesian Optimization (February 20, 2020 2:30pm) https://events.umich.edu/event/70245 70245-17556161@events.umich.edu Event Begins: Thursday, February 20, 2020 2:30pm

Testing and evaluation is a critical step in the development and deployment of connected and automated vehicles (CAVs), and how to generate testing scenario library is a major challenge. In previous studies, to evaluate maneuver challenge of a scenario, surrogate models (SMs) are often used without explicit knowledge of the CAV under test. However, performance dissimilarities between the SM and the CAV under test usually exist, and it can lead to the generation of suboptimal library. In this work, an adaptive testing scenario library generation method is proposed to solve this problem based on Bayesian optimization. A customized testing scenario library for a specific CAV model will be generated as the result of the adaptive process. Compared with a pre-determined library, a CAV can be tested and evaluated in a more efficient manner with the customized library. To validate the proposed method, a cut-in and a highway exit case are studied for safety and functionality evaluation respectively. For both two cases, the proposed method can further accelerate the evaluation process by a few orders of magnitudes.

Nuclear energy provides approximately 20% of the nation’s electricity and is the only green heat source capable of delivering base load power at this time. Plants in the existing nuclear fleet are being retired because they cannot complete financially with natural gas and there is no carbon tax at present. The overnight capital cost for new build nuclear plants in the United States is about $12,500 per kWe , which has to be reduced by about a factor of five to be competitive with the price point of natural gas. Civil construction accounts for between 45% and 50% of the cost of a new build nuclear plant and so drastic reductions in these costs are needed for commercial customers to consider nuclear energy as a source of power generation. The presentation will explore the cost drivers for new build plants, identify differences between building and nuclear construction, describe how poor design decisions lead to dramatic increases in cost, introduce civil civil-engineering strategies for mitigating the effects of external hazards.

On the Empty Miles of Ride-Sourcing Services: Theory, Observation, and Countermeasures (February 27, 2020 2:30pm) https://events.umich.edu/event/70246 70246-17556162@events.umich.edu Event Begins: Thursday, February 27, 2020 2:30pm

The proliferation of smartphones in recent years has catalyzed rapid growth of app-based ride-sourcing services such as Uber, Lyft and Didi Chuxing. A big issue that arises with service expansion is the empty miles produced by ride- sourcing vehicles. To overcome the physical and temporal frictions that separate drivers from customers and effectively reposition themselves towards desired destinations, ride sourcing vehicles generate a significant amount of vacant trips. These empty miles traveled result in an inefficient use of the available fleet and increase traffic demand, posing substantially impacts on system operations. This talk expounds the operational physics underlying the empty miles in ride-sourcing services, and interprets the cause of two critical matching failures that can arise due to some common mechanisms practiced by ride-sourcing platforms. Given the prevalence of the failures in real-world operations, we discuss countermeasures to avoid inefficiencies upon the empty miles, and sustain the system performances. Massive empirical data are employed to evidence the presence of matters in reality as well as the effectiveness of control strategies discussed.
