Non-Conventional Vehicles As A Way Towards Carbon Neutrality In Iceland, Julia Sokolowska Oct 2020

Non-Conventional Vehicles As A Way Towards Carbon Neutrality In Iceland, Julia Sokolowska

Independent Study Project (ISP) Collection

Paris Agreement’s chief objective is to protect the Earth and its inhabitants from a point of no return, when the effects of climate change will be so intense that they will shift the equilibrium of ecosystems. The distinctiveness of this international environmental treaty is that it does not impose climate change mitigation measures, but rather allows nation states to create their own set of measures, the NDCs, to reach the global warming of ‘well below 2oC’ by the end of the century. Thus, Iceland has submitted its own NDC, the Climate Action Plan 2018-2030, which has an ambitious goal of …

Advanced Modeling And Design Methodology For Pavements Using Plasticity-Based Shakedown Theory, Shengli Chen, Chao Sun, Xu Wang, Zhiming Zhang Oct 2020

Advanced Modeling And Design Methodology For Pavements Using Plasticity-Based Shakedown Theory, Shengli Chen, Chao Sun, Xu Wang, Zhiming Zhang

Publications

Pavement design is a process intended to find the most economical combination of layer thickness and material type for the pavement, taking into account the properties of the subgrade soil and the traffic to be carried during the service life of the road. The currently prevalent methods of pavement analysis and design, however, are more or less empirical in U.S., which possess the shortcoming that the important type of pavement distress of rutting related to the accumulation of plastic or permanent deformations cannot be effectively considered. This project proposes an exploratory study on the application of the plasticity theory-based shakedown …

Advancing Transportation Routing Decisions Using Riemannian Manifold Surfaces, Emre Tokgöz, Iddrisu Awudu, Saravanan Kuppusamy Sep 2020

Advancing Transportation Routing Decisions Using Riemannian Manifold Surfaces, Emre Tokgöz, Iddrisu Awudu, Saravanan Kuppusamy

Rohrer College of Business Departmental Research

We consider several real-world driving factors such as the time spent at traffic signs (e.g., yield signs and stop signs), speed limits, and the topology of the surface to develop realistic and accurate routing solutions. Though these factors increase the complexity of modeling, they provide the flexibility to evaluate the routing solutions from different perspectives: cost, distance, and time, to name a few. First, we develop a set of algorithms based on the Riemannian manifold surface (RMS) to factor in the Earth’s curvature to calculate distances. Second, we present a multiobjective, nonlinear, mixed-integer model (MINLP) that minimizes the distance traveled, …

Global Convergence Of Covid-19 Basic Reproduction Number And Estimation From Early-Time Sir Dynamics, Gabriel G. Katul, Asaad Mrad, Sara Bonetti, Gabriele Manolia, Anthony J. Parolari

Civil and Environmental Engineering Faculty Research and Publications

The SIR (‘susceptible-infectious-recovered’) formulation is used to uncover the generic spread mechanisms observed by COVID-19 dynamics globally, especially in the early phases of infectious spread. During this early period, potential controls were not effectively put in place or enforced in many countries. Hence, the early phases of COVID-19 spread in countries where controls were weak offer a unique perspective on the ensemble-behavior of COVID-19 basic reproduction number inferred from SIR formulation. The work here shows that there is global convergence (i.e., across many nations) to an uncontrolled Ro=4.5 that describes the early time spread of COVID-19. This value …

Drought Frequency Analysis Based On The Development Of A Two-Variate Standardized Index (Rainfall-Runoff), Gholamreza Nikravesh, Mohammad Aghababaei, Mohammad Nazari-Sharabian, Moses Karakouzian

Civil and Environmental Engineering and Construction Faculty Research

Drought is one of the most drastic events, which has imposed irreparable damages on human societies and may occur in any climate regime. To define drought, given its properties of multidimensionality and randomity, one cannot rely on a single variable/index (e.g., precipitation, soil moisture, and runoff). Accordingly, implementing a novel approach, this study investigated drought events in two basins with different climatic regimes, using multivariate frequency analyses of drought duration, severity, and severity peak, based on developing a Two-variate Standardized Index (TSI). The index was developed based on the concept of copula, by applying rainfall-runoff data (1974-2019) and comparing them …

Impacts Of Compaction Load And Procedure On Stress-Deformation Behaviors Of A Soil Geosynthetic Composite (Sgc) Mass—A Case Study, Meenwah Gui, Truc Phan, Thang Pham Sep 2020

Impacts Of Compaction Load And Procedure On Stress-Deformation Behaviors Of A Soil Geosynthetic Composite (Sgc) Mass—A Case Study, Meenwah Gui, Truc Phan, Thang Pham

Civil Engineering Faculty Publications

Fill compaction in the construction of Geosynthetic Reinforced Soil (GRS) mass is typically performed by operating a vibratory or roller compactor, which in turns imposed a compaction load in direction perpendicular to the wall face. The compaction process resulted in the development of the so-called compaction-induced stress (CIS), which may subsequently increase the stiffness and strength of the fill material. Compaction process is normally simulated using one of the following compaction procedures—(i) a uniformly distributed load acting on the top surface of each soil lift, (ii) a uniformly distributed load acting on the top and bottom surface of each soil …

Development Of Zeolitic Imidazolate Frameworks For Enhancing Post-Combustion Co2 Capture, Dustin Lee Sep 2020

Development Of Zeolitic Imidazolate Frameworks For Enhancing Post-Combustion Co2 Capture, Dustin Lee

Master's Theses

Post-combustion CO2 capture is a promising approach for complementing other strategies to mitigate climate change. Liquid absorption is currently used to capture CO2 from post-combustion flue gases. However, the high energy cost required to regenerate the liquid absorbents is a major drawback for this process. As a result, solid sorbents have been investigated extensively in recent years as alternative media to capture CO2 from flue gases. For example, metal organic frameworks (MOFs) are nanoporous materials that have high surface areas, large pore volumes, and flexible designs. A large number of MOFs, however, suffer from 1) low CO …

Evaluation Of Mixtures And Pavement Performance For Rehabilitation Methods, Mohammad Rahmani, Gabriel Nsengiyumva, Yong-Rak Kim, Jiong Hu Sep 2020

Evaluation Of Mixtures And Pavement Performance For Rehabilitation Methods, Mohammad Rahmani, Gabriel Nsengiyumva, Yong-Rak Kim, Jiong Hu

Nebraska Department of Transportation: Research Reports

Pavement rehabilitation practice involves milling an asphalt surface and placing a new layer. The incorporation of reclaimed asphalt pavement (RAP) mixtures brings cost savings and preserves the environment and natural resources. However, the use of recycled materials can compromise pavement performance, in particular, RAP can contribute to cracking because the mixtures with recycled materials become more brittle. In Nebraska, pavement rehabilitation has mostly been conducted by milling old 4-in. asphalt surface and placing a new 4-in. layer. Due to the potentially increased use of RAP mixtures for pavement rehabilitation, it is necessary to look into potential applications of RAP-induced overlay …

Co2 Curing Efficiency For Cement Paste And Mortars Produced By A Low Water-To-Cement Ratio, Seong Ho Han, Yubin Jun, Tae Yong Shin, Jae Hong Kim

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Curing by CO2 is a way to utilize CO2 to reduce greenhouse gas emissions. Placing early-age cement paste in a CO2 chamber or pressure vessel accelerates its strength development. Cement carbonation is attributed to the quickened strength development, and CO2 uptake can be quantitatively evaluated by measuring CO2 gas pressure loss in the pressure vessel. A decrease in CO2 gas pressure is observed with all cement pastes and mortar samples regardless of the mix proportion and the casting method; one method involves compacting a low water-to-cement ratio mix, and the other method comprises a …

Numerical Modeling Of Wave- And Current-Supported Turbidity Currents Over Erodible Bed, Sahar Haddadian

LSU Doctoral Dissertations

The physical processes that route sediments from nearshore to the continental margin provide vital information to the global assessment of the geochemically important matter and the life in the ocean. Therefore, understanding these processes at the fundamental level will help develop accurate models that can be integrated into operational ocean models. Wave- and current-supported turbidity currents (WCSTCs) are one of the mechanisms that deliver sediments to the continental margin. WCSTCs are slow-moving turbidity currents where near-bed turbulence driven by strong surface waves and/or currents, tide- and/or wind-driven, maintain the turbidity current in motion.

Modeling Strategies For Structures Using Ductile Concrete Materials In Seismic Applications, Hasan Tariq Aug 2020

Modeling Strategies For Structures Using Ductile Concrete Materials In Seismic Applications, Hasan Tariq

Dissertations

High-Performance Fiber-Reinforced Cementitious Composites (HPFRCCs) have made striking advances over the last two decades as an alternative material to replace ordinary concrete in regions of high seismic intensities. In contrast to ordinary concrete which has a brittle tensile response, HPFRCCs exhibit tensile strain hardening and multiple crack propagation. The application of HPFRCC in various structural components demonstrate effectiveness by improving damage resistance, deformation capacity, and energy absorption capacity. Despite these benefits, the failure mode of reinforced HPFRCC components is dominated by reinforcement fracture unlike traditional reinforced concrete components which fail in flexure by crushing. The unique behavior of HPFRCC members …

Ranking Volatility In Building Energy Consumption Using Ensemble Learning And Information Entropy, Kunal Sharma, Jung-Ho Lewe Aug 2020

Ranking Volatility In Building Energy Consumption Using Ensemble Learning And Information Entropy, Kunal Sharma, Jung-Ho Lewe

Georgia Journal of Science

Given the rise in building energy consumption and demand worldwide, energy inefficiency detection has become extremely important. A significant portion of the energy used in commercial buildings is wasted as a result of poor maintenance, degradation or improperly controlled equipment. Most facilities employ sensors to track energy consumption across multiple buildings. Smart fault detection and diagnostic systems use various anomaly detection techniques to discover point anomalies in consumption. While these systems work reasonably well in detecting equipment anomalies over short-term intervals, further exploration is needed in finding methods that consider long-term consumption to detect anomalous buildings. This paper presents a …

Developing A Common Framework For A Bridge Management System At National Level, Thomas Neeson, Myra Lydon, Kristopher Campbell, Nicola Ann Stevens, Adelle Marshall, Aleksander Novakovic

Civil Engineering Research in Ireland 2020

Transport infrastructure is directly impacted by climate change as extreme weather conditions account for 10-35% of delays/service interruptions to road and rail infrastructure. The current reactive method of maintaining bridges within these infrastructure systems results in a lack of contingency capacity and ultimately a reduced ability to adapt to uncertain future needs. To allow infrastructure providers to prepare for future events, there is a need to develop asset management systems (AMS) with embedded decision-making support which considers factors such as climate change and population growth. A National approach would enable strategic risk assessment to mitigate the consequences of climate change …

Characterization And Performance Of Cement-Based Thermoelectric Materials, Ruchita Jani, Niall Holmes, Roger P. West, Kevin Gaughan, Xiaoli Liu, Esther Orisakwe, Conrad Johnston, Ming Qu, Jorge Kohanoff, Lorenzo Stella, Hongxi Yin Aug 2020

Characterization And Performance Of Cement-Based Thermoelectric Materials, Ruchita Jani, Niall Holmes, Roger P. West, Kevin Gaughan, Xiaoli Liu, Esther Orisakwe, Conrad Johnston, Ming Qu, Jorge Kohanoff, Lorenzo Stella, Hongxi Yin

Civil Engineering Research in Ireland 2020

Thermoelectric materials enable direct conversion of thermal energy to electricity. Ambient heat energy harvesting could be an effective route to convert buildings from being energy consumers to energy harvesters, thus making them more sustainable. There exists a relatively stable temperature gradient (storing energy) between the internal and external walls of buildings which can be utilized to generate meaningful energy (that is, electricity) using the thermoelectric principle. This could ultimately help reduce the surface temperatures and energy consumption of buildings, especially in urban areas.
