LAB NEWS
Dr. Astrid Layton selected to attend the 2023 EU-US Frontiers of Engineering (EU-US FOE) Symposium hosted by the National Academy of Engineering and Nokia Bell Labs
BiSSL group director Dr. Astrid Layton was selected to attend the 2023 EU-US Frontiers of Engineering (EU-US FOE) Symposium hosted by the National Academy of Engineering (NAE) and Nokia Bell Labs. The National Academy of Engineering holds an annual US Frontiers of Engineering symposium that brings together 60 highly accomplished early-career engineers from EU and US universities, companies, and government to discuss leading-edge research and technical work across a range of engineering fields. Convening engineers from disparate fields and challenging them to think about developments and problems at the frontiers of areas different from their own can lead to a variety of desirable results. These include collaborative work, the transfer of new techniques and approaches across fields, and the establishment of contacts among the next generation of leaders in engineering. The objectives for the bilateral meetings also have the added element of facilitating international cooperation and understanding. The symposium – which covers the topics of The Quantum Era Challenge, Future Challenges in Additive Manufacturing, Clean Hydrogen, and The Computational Era of Life Sciences – will take place from October 15-18 at the National Academies’ Beckman Center in Murray Hill, New Jersey.
Invited Graduate Research Seminar at University of Michigan
Dr. Layton gave an invited seminar presentation at University of Michigan titled “How Nature’s Systems Can Guide More Resilient and Sustainable Human Network Design” Sept. 26, 2023. The talk coincided with some excellent collaborative brainstorming with Dr. Sita Syal and other new contacts.
Abstract: Inspiration from nature has produced some fascinating, novel, and life-changing solutions for the human world. Most of these bio-inspired designs however have been product-based, but taking a systems perspective when we look to nature taps inspirations that can improve the critical networks we depend on. This talk focuses on biological ecosystems, in particular, complex networks of interacting species that are able to support individual needs while maintaining system-level functions during both times of abundance and unexpected disturbances. This talk will show how these networks can offer inspiration for achieving both sustainability AND resilience. Quantitative ecosystem descriptors and analysis techniques adapted from ecology enable desirable ecosystem characteristics to be used as design guides for things like industrial resource networks, water networks, supply chains, and power grids.

4 BiSSL Students have Papers Accepted to IDETC-CIE 2023
We’re happy to share that 3 BiSSL papers, written by 4 BiSSL researcher students, have been accepted for publication and presentation in Boston, MA in August at IDETC-CIE 2023.
BiSSL alum Samuel Blair, in collaboration with our Georgia Tech partners Dr. Julie Linsey and Claire Crose, has a paper accepted to the Design Theory and Methodology division titled “Measuring the Health of Makerspaces During Large Disruptions Such as the COVID-19 Pandemic.”
As the popularity of makerspaces and maker culture has skyrocketed over the past two decades, numerous studies have been conducted to investigate the benefits of makerspaces for university students and how to best establish an inclusive, welcoming environment in these spaces on college campuses. However, unprecedented disruptions, such as the COVID-19 pandemic, have the potential to greatly affect the way that students interact with makerspaces and the benefits that result. In this study, a survey asking about prior makerspace involvement, tool usage, and student demographics was administered to students who use academic makerspaces at two large public universities. Survey data was collected for three semesters (Fall 2020, Spring 2021, and Spring 2022) and spanned both during and after the height of the COVID-19 pandemic. To quantify the differences between the semesters, nestedness and connectance metrics inspired by ecological plant-pollinator networks were utilized. These ecological metrics allow for the structure of the interactions of a network to be measured, with nestedness highlighting how students interact with tools and connectance with the quantity of student-to-tool interaction. The network analysis was used to better gauge the health of the makerspace and the type and frequency of interactions between tools. The raw survey data combined with the ecological metrics provided unique insight into the struggles the makerspaces encountered throughout the pandemic. It was found that nestedness, a measure of system stability, decreases with a decrease in tool usage. Additionally, the higher the connectance the more students interacted with the space. Utilizing metrics such as these and better understanding student tool interactions can aid makerspaces in monitoring their success and maintaining a healthy and welcoming space, as well as tracking the current health of the space. In combination with the survey results, a deep understanding of what challenges the space is facing can be captured.

BiSSL Ph.D. students Hadear Hassan and Emily Payne collaborated on the paper titled “Quantifying the Sustainability and Robustness of Manufacturing Systems Using Energy and Ecological Network Analyses,” to be presented by Hadear in August in the Design For Manufacturing and Life Cycle division (DFMLC).
Global issues, such as supply chain disruptions, have increased awareness of the importance of manufacturing systems being able to quickly bounce back from disturbances. This necessary response is in addition to the importance of mitigating climate change, maintaining market competitiveness, and eliminating unnecessary waste. Two analysis types are compared here: 1) a thermodynamic exergy analysis to quantify a manufacturing system’s energy and material efficiency and 2) an ecological network analysis as a quantitative representation of the system’s sustainability and robustness. Several manufacturing structures, including different processes ranging from the traditional to advanced, like injection molding and binder jetting, are examined in terms of the system response to changes. The findings indicate that the thermodynamic approach efficiently evaluates the efficacy of energy and resource conversion to create a final product. The ecological network approach was also found to provide useful insights on both the environmental efficiency of the systems as well as the resilience. These results are useful when combined for suggesting system layouts and operations that holistically improve a manufacturing system’s design. The findings indicate that existing manufacturing infrastructure needs to be redesigned to better withstand and recover from unforeseen disruptions. Introducing features such as recyclability and combining multiple types of manufacturing processes can enhance the overall resilience of the system. The work suggests that the bio-inspired systems analysis approach when coupled with connectivity and energy-related factors can lead to enhanced manufacturing system designs.

BiSSL Ph.D. student Emily Payne and undergraduate alum Hannah Wagner collaborated on the paper titled “Resilience and Sustainability in Certified Green Buildings: Applying Ecosystem Concepts to Aid in More Dynamic Green Communities,” to be presented by Emily in August in the Design For Manufacturing and Life Cycle division (DFMLC).
Sustainable and resilient buildings ensure safety and lifespan while also benefiting the environment. Leadership in Energy and Environmental Design (LEED) is one respectable certification that many buildings can receive to ensure that they are meeting future climate and energy goals. However, LEED buildings have credits that do not necessarily agree with creating a sustainable environment. When comparing the orientation of LEED points and their relationship to the building and community to ecological structures, we found that a rearrangement of categories can provide visualization for organized recycling and higher cyclicity through ecological network applications. This relationship was applied to a new scorecard which has results indicating that if designers choose to meet criteria where one credit in each grouping is implemented in construction, then a sustainable building can still be efficient as well as recognized as a green building.

Two BiSSL Papers Presented at the Annual Conference on Systems Engineering Research (CSER2023)
Abheek Chatterjee and Luis Rodriguez are presenting their first-authored papers at the annual CSER conference hosted by Stevens Institute of Technology in Hoboken, New Jersey. The conference is centered around “Systems Engineering Toward a Smart and Sustainable World.”
Urban water distribution networks have provided potable water to communities and households worldwide over the last century. Within the last two decades, there has been a rise in complications with water distribution systems meeting demands. Urban water distributions fail to meet demands due to increases in natural and man-made disturbances, population growth, and aging water distribution network structures. These issues have caused urban water distribution system designers and decision-makers to shift their interests from focusing solely on efficiency to designs capable of meeting customer potable water demands under normal operations and during disturbances. Ecology, specifically biological ecosystems, provides system resilience inspiration, taken from their structure and functioning that has survived disturbances over millions of years. The work here investigates mimicking the decentralization of food webs to improve network resilience by incorporating decentralized water storage tanks, using the established Two Loop Network (TLN) as a case study. TLN is an introductory water network provided by the University of Exeter for system engineers and designers to test optimization and exploratory techniques. The case study was selected due to its simplistic design which allowed the authors to understand the effects of decentralizing the network toward improving its ability to handle disruptions. The findings suggest decentralization can improve the water network resilience a minimum of three times as much as the original network’s design. Furthermore, introducing decentralization was also found to increase the system’s ability to meet the demand for all nodes during disruptions, something the original case was unable to accomplish while simultaneously reducing the amount of freshwater consumed during disruptions.

A microgrid is a localized energy grid that can disengage from the traditional grid and operate independently. Microgrids can be conceptualized as System of Systems: networked integration of constituent systems that together achieve novel capabilities. Improving resilience (the ability to survive and recover from disruptions) and reducing the cost of energy are critical considerations in microgrid design. However, microgrid resilience evaluation techniques require explicit disruption models – information that is not readily available in the early design stages. Therefore, these models cannot inform early-stage design decisions when changes can be made affordably. Recent research has indicated that Ecological Network Analysis is a promising tool for the design of resilient and affordable System of Systems. However, this approach has not yet been tested as a tool for microgrid design. This work provides an adapted Ecological Network Analysis framework that accounts for two unique architectural features of microgrids: (a) energy storage, and (b) integration of different types of energy generation technology. The Ecological Network Analysis based assessment of microgrid architectures is compared against their resilience and cost of energy evaluations using a state-of-the-art tool. The results of the comparison provide support for the use of Ecological Network Analysis as a reliable early-stage decision-support tool for resilient microgrid design.

The BiSSL group joins 1 of 16 teams that have been selected for NSF’s Convergence Accelerator Grant
December 19, 2022
NSF’s Convergence Accelerator is developing use-inspired solutions to address challenges aligned to the manufacturing, reuse and recycling of critical materials and products. The BiSSL group joins one of sixteen teams that have been selected for the program’s Track I: Sustainable Materials for Global Challenges.
ABSTRACT. This track I NSF’s Convergence Accelerator aims to converge advances in fundamental materials science with innovative design and manufacturing methods to couple their end-use and full life-cycle considerations for environmentally- and economically sustainable materials and products. Guided by this principle and motivated by the global goal of Net-Zero Emissions by 2050, this project focuses on demonstration of a sustainable production and manufacturing process for large-scale hydrogen deployment and critical materials mining from earth’s abundant hypersaline brines (e.g., seawater). Hydrogen is a green fuel that can help accelerate decarbonization processes, and materials such as Lithium and Rare Earth elements that are critical to U.S. supply chain independence. This project emphasizes transformation from a linear to a circular economy; it enables a convergent, innovative team of universities, industry partners, government agencies, and students/trainees to ensure that the knowledge developed transitions effectively into many aspects of practice. The proposed circular use of water for fuel by renewable energy and extraction of critical materials for renewable energy production has broad societal impacts for a sustainable future. This project integrates multidisciplinary thinking into the undergraduate and K-12 curriculum, producing future engineers and scientists with skills and interests to work on multidisciplinary problems. This research supports and benefits the local community, such as the Oregon Coast’s Blue Sector Partnership Network consisting of partners from workforce development, school districts (CTE), industry, government, research, maritime, municipalities, and blue technology.
This proposal aims to demonstrate the sustainable mining of green hydrogen in parallel with value-added critical elements from hypersaline brines (e.g., seawater) for clean energy applications. Motivated by the global goal of Net-Zero Emissions by 2050, circular economy principles guide our development of sustainable processes for materials/fuels production, utilization, and recycling. Seawater represents the most abundant resource on the earth, with immense surface accessibility and large amounts of solubilized elements imperative for clean energy technologies. Seawater can also be split using renewable energy (e.g., solar) to obtain hydrogen fuel, with benign oxygen gas as a byproduct. Hydrogen presents a zero-emission fuel (producing water in a fuel cell), part of a circular sustainable process. Developing an integrated solution for extracting hydrogen and critical elements from seawater requires a multidisciplinary team from universities, industry partners, government agencies, and students/trainees. With our patented technologies and research results in critical areas, we aim to integrate multidisciplinary knowledge, tools, and modes of thinking under the guidance of circular economy principles to accelerate and converge our research to two integrated prototypes: a mineral-water separation reactor and downstream electrolyzer (producing hydrogen from the reduced-saline effluent). In addition to this prototyping, we will also identify in Phase 1 additional areas of expertise through team activities to prepare our Phase 2 project. In parallel, we will engage local stakeholders (focused on the Oregon Coast with our local expertise) and create training programs to educate next-generation workforces with innovative circular concepts in both Phases.

Invited Research Seminar at the University of Miami, Department of Industrial and Systems Engineering
October 21, 2022
Dr. Astrid Layton was invited by the Department of Industrial and Systems Engineering at the University of Miami to share BiSSL group work on bio-inspired system resilience. Her talk, titled “Using Biological Inspiration to Guide the Design of Human Networks for Resilience” is also now featured in the University’s Climate Resilience Academy UM YouTube series.
Abstract: Biological ecosystems have been through millions of years of R&D, producing complex systems of systems made up of interacting species that are able to support individual needs while maintaining system-level functions. In this talk Dr. Layton will show that ecosystems offer a relatively untapped source of design inspiration for improving the resilience of our human engineered networks in conjunction with goals like sustainability and cost. Quantitative descriptors and analysis techniques are adapted from ecology, enabling desirable ecosystem characteristics to be used as optimization and design guides for industrial resource networks (or eco-industrial parks, EIPs), water networks, supply chains, cyber-physical systems, and power grids. Ecological characteristics such as high levels of materials/energy cycling and a unique balance between redundant and efficient pathways offer novel routes to achieving traditional engineering goals.

Huge congratulations to BiSSL alum Jessica Ezemba on her first authored paper being accepted to the Journal of Mechanical Design!
September 2022
Jessica was an undergraduate researcher student in BiSSL while at Texas A&M. Her work combining her interest in brain injuries with bio-inspired design turned into a full-length journal article that has now been accepted for publication in the Journal of Mechanical Design. Jessica is currently a graduate student at Carnegie Mellon University in their MIIPS program and is planning on pursuing a Ph.D. thereafter.
The paper is titled “Bio-Inspired Avenues for Advancing Brain Injury Prevention” and can be found here:
Abstract: “Bio-inspired design is a highly promising avenue for uncovering novel traumatic brain injury prevention equipment designs. Nature has a history of providing inspiration for breakthrough innovations, particularly in cases when the traditional engineering mindset has failed to advance problem solving. This work identifies patterns and trends in the ways that nature defends against external stimuli and predators, investigating them with the goal of highlighting promising inspiration for brain injury prevention. Two key strategies were found missing in engineering applications while identifying patterns and strategies used in nature: 1) connections between layers in multi-layered material structures and 2) the use of multiple strategies in a single design. Nine organisms are highlighted in detail as examples of patterns in biological methods of protection, both on a macro and microscale. These findings include the coconut’s shell, the pomelo fruit’s peel, the golden scale snail’s shell, the ironclad beetle’s exoskeleton, the woodpecker’s skull, the Arapaima fish’s scales, conch shells, and the dactyl club of shrimp. The results highlight knowledge gaps preventing these findings from being applied as well as recommendations for moving towards their use in engineering design.”

Garrett’s thesis is titled: “Using Bio-Inspired Techniques to Design for Improved Sustainability and Robustness in Net Zero Communities”
In the global effort to combat climate change, the continued emergence of Net Zero Communities (NZCs) can play a large role in establishing a sustainable foundation on which progress can be made. NZC design, however, is complicated by the need to balance the system’s ability to achieve sustainable performance with its ability to maintain system operation during disturbances. These two design objectives, sustainable use of resources and system robustness, are often found in opposition to one another, but design inspiration can be taken from biological ecosystems, which have benefitted from generations of incremental evolution to display positive network characteristics with regards to both efficient resource use and robustness. This thesis focuses on applying the knowledge of what makes these ecosystems successful, as well as the techniques ecologists use to characterize them, to identify Net Zero (NZ) modifications that can simultaneously improve both of the aforementioned design objectives. First, a dataset of NZCs including quantitative energy and water flows throughout each case is constructed. This dataset then enables the use of Ecological Network Analysis on NZC networks, specifically identifying Finn’s Cycling Index (FCI) and Degree of System Order (DoSO) as metrics corresponding to sustainable and robust design, respectively. The results show that for the NZ modifications tested, a strong correlation exists between FCI and NZ performance, suggesting that FCI can be used as a proxy for sustainable network behavior. Additionally, a negative correlation emerges between FCI and DoSO. This result is significant as lower DoSO is indicative of improved network robustness, especially in the face of increasingly large disturbances, meaning that the modifications tested were in direct support of both sustainability and robustness. These findings hold true through disturbance testing, where the modified networks with higher NZ performance are also able to maintain the highest levels of operation during a disturbance. As such, this thesis provides proof of concept that bio-inspiration can be used to inform NZC design and impart improved sustainability and robustness into the networks.

Tyler’s thesis is titled: “Designing and Optimizing Supply Chain Networks for Resilience using Ecological Network Analysis”
Abstract: Traditional supply chain policies and design efforts, such as lean-manufacturing, prize efficiency over all other factors and are being challenged as supply chains struggle to bounce back from recent disruptions. Supply chain design guidelines that address resilience require a balanced approach between efficiency and redundancy, one that presents flexibility in a way that acknowledges profit requirements. Ecological Network Analysis reveals a unique balance of pathway efficiency and redundancy within ecosystems. This balance results in efficient steady-state operations and survival upon disruption. Supply chain networks are evaluated here using the same ecological analysis, providing design guidelines for achieving a balanced system-level resilience. Significant insights include that the validity of ecologically inspired supply chain design is contingent on the supply chain’s properties and that under the right conditions, the ecological balance of efficiency and redundancy can vastly improve the performance of supply chains during disruptions.

BiSSL Collaborative Paper Accepted to the 2022 ASEE Conference & Exposition
March 9, 2022
A collaborative paper with Dr. Julie Linsey at Georgia Institute of Technology, led by BiSSL Ph.D. student Samuel Blair and co-written with MS student Garrett Hairston, has been accepted to the 2022 ASEE Conference & Exposition. The paper, titled “Modularity Analysis of Makerspaces to Determine Potential Hubs and Critical Tools in the Makerspace,” was accepted to the Design in Engineering Education Division. The conference will be held in Minneapolis, MN at the end of June.
Abstract: Globally, universities have heavily invested in makerspaces. Purposeful investment however requires an understanding of how students use tools and how tools aid in engineering education. This paper utilizes a modularity analysis in combination with student surveys to analyze and understand the space as a network of student-tool interactions. The results show that a modularity analysis is able to identify the roles of different tool groupings in the space by measuring how well tool groups are connected within their own “module” and their connection to tools outside of their module. A highly connected tool in both categories is considered a hub that is critical to the network. Poorly connected tools indicate insignificance or under utilization. Makerspaces at two universities were investigated: School A with a full-time staff running the makerspace and School B run by student-volunteers. The results show that 3D printers and metal tools are hubs at School A and 3D printers, metal tools, and laser cutters are hubs at School B. School B was also found to have a higher overall interaction with all the tools in the space. The modularity analysis results are validated using two-semesters worth of student self-reported survey data. The results support the use of a modularity analysis as a way to analyze and visualize the complex network interactions occurring within a makerspace, which can support the improvement of current makerspaces and development of future makerspaces.

New BiSSL Publication in the Systems Engineering journal
August 18, 2021
Big congratulations to BiSSL PhD student Abheek Chatterjee for his paper “Ecology‐inspired resilient and affordable system of systems using degree of system order” – which investigates applying ecological resilience measures to the design of Systems of Systems (SoS) and has now been published!
Abstract: This research tests the value of using an ecology-inspired architectural metric, called the metric Degree of System Order (DoSO), to identify resilient and affordable engineered System of Systems (SoS) architectures. Analysis of long-surviving biological ecosystems (nature’s resilient SoS) using DoSO has revealed a unique balance of efficient and redundant interactions in their architectures. This balance is hypothesized to enable both effective resource utilization under normal operation and adaptability to survive and recover from perturbations. Optimal trade-off between resilience (the ability to survive and recover from disruptions) and affordability is highly desirable in engineering SoS as well. To test this analogy, the resilience vs. affordability tradespace of a large number of notional SoS architectures is investigated using the DoSO metric. Results indicate that the majority of Pareto optimal SoS architectures, under various disruption scenarios, lie in the ecologically identified favorable DoSO range. Further, SoS architectures within this DoSO range were found to have better resilience and affordability attributes, in general, than the architectures outside it. Evaluation of the DoSO metric does not require detailed simulations and is the first network architecture metric to consider resilience vs. affordability trade-offs, making it a valuable addition to the SoS engineering toolset.

Two student-led conference papers accepted to the 2021 IDETC-CIE conference!
April 9, 2021
Three BiSSL students have had conference papers accepted to the 2021 International Design Engineering Technical Conference! PhD candidate Abheek Chatterjee and MS student Tyler Wilson have co-authored a paper on modifying bio-inspired system design methodologies for supply chains, enabling the impact of storage to be considered when applying resilience characteristics from nature. MS student Garrett Hairston has had his first, first-authored paper accepted that focuses on using a system perspective to develop net zero design guidelines for multi-use (industrial, residential, commercial) communities from biological food webs.
Abstract: “Supply chain policies and design efforts are traditionally focused on efficiency objectives such as reducing operational costs. With the occurrence of the most devastating pandemic in decades and the continually increasing prevalence of natural disasters, this focus has been challenged, and the need to focus on supply chain resilience has become apparent. Achieving long-lasting sustainable development in supply chains requires a balance of efficiency-focused measures that enhance economic and environmental sustainability and resiliency measures. Ecological Network Analysis has revealed a unique balance between pathway efficiency and redundancy in ecosystems’ network architecture. This enables both efficient operations under normal circumstances and resilience to perturbations. This same analysis can be used to evaluate the balance of sustainability and resilience in supply chain networks, providing insights into what kind of supply chain design and policy decisions lead to more ecosystem-like architectures. This study lays the groundwork for such efforts by studying four supply chain topologies (formed by prevalent supply chain strategies) using ENA. Inventory (storage) is not well understood in the typical flow analysis used in ENA but is an essential facet of supply chain design and must be included in a supply chain analysis. This study overcomes this limitation by proposing a method to include inventory in the ENA framework. The analysis conducted revealed two significant insights: (a) the agile supply chain strategy is the most ecologically similar and (b) it is possible that there are optimal inventory levels (given partnership strategies) to utilize bio-inspiration in supply chain design.”

Abstract: “Much emphasis is placed on the role of Net Zero Communities (NZCs) in achieving a sustainable future. Systems research on the topic, including the application of bio-inspired techniques already used on other human networks, is currently hindered by the lack of case studies documenting the structure and quantity of energy, water, and waste flows within realistic NZCs. This work proposes and preliminarily tests a method of generating a database of hypothetical-realistic NZCs by expanding the system boundaries for well-documented Eco-industrial Park (EIP) networks. The expansion includes residential and commercial actors from the community surrounding the EIP. Past studies using Ecological Network Analysis (ENA) to improve the environmental and economic performance of these EIPs have resulted in a quantitative database of case studies. Combining these industrial hubs to nearby residential, commercial, agricultural, etc. actors can generate potential multi-use networks on which similar design work can be conducted. Three EIP to NZC cases are generated and analyzed focusing on their system structure. Cyclicity, an ENA metric used to quantify the presence and complexity of cyclic pathways in a network, has been shown to promote the efficient use of resources in both biological and human networks. Cyclicity values for the original EIP networks, the community additions, and the potential NZC case studies reveals that there are many meaningful interactions that occur between actors that are only visible once the system boundaries are expanded to the NZC level. This offers a glimpse into the potential benefits of approaching the NZ problem, and sustainable living more generally, on a system scale – an analysis that will be further enabled by the generation of an NZC database initiated by this work.”

Collaborative student-led conference paper accepted to the 2021 ASEE Annual Conference & Exposition
April 6, 2021
BiSSL PhD student Samuel Blair has had his first, first-authored conference paper accepted to the American Society of Engineering Education 2021 annual conference! The conference was to be held in Long Beach, CA but unfortunately has been since shifted to an entirely virtual format. The paper is titled “Bipartite Network Analysis Utilizing Survey Data to Determine Student and Tool Interactions in a Makerspace” and is a collaborative work with our partners at Georgia Institute of Technology, Dr. Julie Linsey and her MS student Henry Banks. The conference will take place July 26-29, 2021.
Abstract: “Engineering makerspaces are a powerful new tool in the educators’ toolbox. A growing body of empirical data demonstrates their benefits to student learning, but more needs to be done to ensure they meet their full potential. Analyzing the design of these spaces to maximize student tool interactions and identify barriers to entry supports goals for these spaces to be inclusive environments were all students are comfortable. The representation of student interactions with tools in a graph form enables analysis on the tools by mapping combinations between tools and shared student. The bipartite model of the network allows for students to be the “actors” while the tools are the “events” that students interact with. Using the one way interaction allows for a matrix simplifying the complex interactions in the space. The matrix can then be manipulated to yield important information about makerspaces. The results of this ongoing research propose advice regarding what tools and tool types are the most accessible to students, primarily high interaction tools such as basic 3D printers and handheld tools. Utilizing the analysis can also
reveal how tools depend on higher interaction tools such as the advanced forms of 3D printing, as well as what student groups have may need extra support or outreach to increase their inclusion.”

Research paper accepted to the Journal of Cleaner Production
April 5, 2021
BiSSL MS alum Jewel Williams just had her coauthored full length research paper accepted and published in the Journal of Cleaner Production! The paper, titled “Matrix Trays: From Waste to Opportunities,” advances a circular economy approach and was done in collaboration with the Department of Architecture Dr. Ahmed K. Ali and his PhD student Patricia Kio. The work couldn’t have been done without the 2019 Mechanical Engineering senior design team of Alexandra Stewart, Zachary Merrill, Austin Grosklags, Miguel Cervantes, and Joseph Bustillo. This team came up with a case study design that reused matrix trays – which are currently a major single-use plastic filling our landfills – as part of an interdisciplinary seed grant from Texas A&M.
Abstract: “Matrix Trays are single-use plastic carriers used to transport integrated chips and circuit board components during automated test and assembly processes for Printed Circuit Boards. These trays represent a significant yet consistent waste stream; primarily in the electronics industry and many other industries that integrate microchips into their products especially the automotive industry. By the end of 2017, the National Sword Policy which was implemented by China on plastic waste import from other countries and especially the United States catalyzed a huge crisis and forced manufacturers and companies to deal with their own plastic waste streams. This study presents two alternative approaches of reusing trays to the reduced conventional recycling practices which have caused used trays to remain in storage or be deposited in landfills. Approaches including a students’ design competition and a proof of concept case study for an autonomous shading device are presented. The shading device was designed, tested and validated. Trays were transformed from waste into 13 possible products showing that a circular economy and industrial symbiosis can be achieved by integrating multidisciplinary reuse approaches for by-product reuse and sustainable industry practices. Environmental and economic impacts were evaluated comparing reuse to recycling, combustion and landfilling. The results showed that reusing trays reduces energy consumption and greenhouse gas emissions.”

BiSSL PhD student Abheek Chatterjee and alumn Colton Brehm (MS) just had their full length research paper accepted and published in the journal Resources, Conservation & Recycling! The paper, titled “A Quantitative Benefits Evaluation of Ecologically-Inspired Nested Architectures for Industrial Networks,” investigates the use of ecological nestedness – a structural characteristic of ecological food webs, to guide the design of eco-industrial parks and other resource networks to improve it’s ability to survive network disturbances AND to guide inter-actor connections based on resource cost and distance between actors.

Abstract: “Industrial Symbiosis (IS), inspired by the highly effective resource utilization found in nature, advocates byproduct-exchange partnerships between industries to reduce raw material use, emissions, and waste generation while promoting economic growth. Ecological research on mutualistic ecosystems (such as plant-pollinator networks) has found a connection between high values of nestedness, a unique linkage distribution strategy, and effective resource utilization. The present work is the first to test the benefits of nested architectures for IS goals, a characteristic thus far overlooked in bio-inspired IS efforts. A generated large dataset of hypothetical-realistic Industrial Water Networks spanning the entire nestedness domain shows that highly nested designs significantly reduce resource consumption. Circumstances where these savings outweigh any additional infrastructure and operation costs are also shown, highlighting that low to moderate resource abundance and manageable geographical dispersion between participating industries (conditions that commonly generate interest in IS) are particularly favorable for nested architectures. Ecologically-similarly nested IS networks, especially those with highly connected high-throughput industries, are also found to have a reduction in negative impacts during pipeline disruptions. The results provide promising evidence that the principle of nestedness can be a powerful quantitative bio-inspired design guideline for IS, capable of simultaneously addressing environmental, economic, and resiliency concerns.”

Collaborative Research paper accepted to the Journal of Mechanical Design
November 18, 2020
Abstract: “In this work, we show that bioinspired function-sharing can be effectively applied in engineering design by abstracting and emulating the product architecture of biological systems that exhibit function-sharing. Systems that leverage function-sharing enable multiple functions to be performed by a single structure. Billions of years of evolution has led to the development of function-sharing adaptations in biological systems. Currently, engineers leverage biological function-sharing by imitating serendipitously encountered biological structures. As a result, utilizing bioinspired function-sharing remains limited to some specific engineering problems. To overcome this limitation, we propose the Function-Behavior-Structure tree as a tool to simultaneously abstract both biological adaptations and the product architecture of biological systems. The tool uses information from an existing bioinspired design abstraction tool and an existing product architecture representation tool. A case study demonstrates the tool’s ability to abstract the product architectural characteristics of function-sharing biological systems. The abstracted product architectural characteristics are then shown to facilitate problem-driven bio-inspiration of function-sharing. The availability of a problem-driven approach may reduce the need to imitate biological structures to leverage biological function-sharing in engineering design. This work is a step forward in analyzing biological product architectures to inspire engineering design.”

“Whether intended or not, engineered, industrial systems often mirror those found in the natural world. Case in point: the relationship between today’s electrical power grid and the way food chains function.
Drawing on principles from bio-designed systems—in this case the food web—will help scientists build more resilience into the electrical power grid, said Astrid Layton, an assistant professor of mechanical engineering at Texas A&M University. She collaborates with Katherine Davis, an A&M assistant professor of electrical engineering, on the project.
A more resilient power grid means reducing the damage from outages and shorten their duration, Layton said.”
Texas A&M’s Civil and Environmental Engineering Department: Environmental, Water Resources, and Coastal Engineering Graduate Seminar
September 7, 2020
Honored to have been invited to give a graduate seminar in A&M’s Civil Engineering Department for the Environmental, Water Resources, and Coastal Engineering students. Feel free to virtually stop by if you’re free, I’ll be talking about my research regarding “Bio-Inspired System Design: Using Nature to Improve the Resilience and Sustainability of Our Water Networks.”
Seminar Abstract: Biological ecosystems have been through millions of years of R&D, producing complex networks of interacting species that are able to support individual needs while maintaining system-level functions. In this talk Dr. Layton will show that biological networks offer a relatively untapped source of design inspiration for improving the sustainability and resilience of our water distribution networks. Quantitative descriptors and analysis techniques are adapted from ecology through close collaboration with ecologists, enabling desirable ecosystem characteristics to be used as optimization guides for industrial water networks. Characteristics such as a high level of cycling of materials/energy within the system and a unique balance between redundant and efficient pathways are connected back to the achievement of traditional engineering goals such as cost and robustness.

August 18, 2020
Abheek his paper was written in collaboration with Dr. Richard Malak, in CIE’s SEIKM division titled “Exploring a Bio-Inspired System of Systems Resilience vs. Affordability Tradespace“
Abstract: “The objective of this study is to investigate the value of an ecologically inspired architectural metric called the Degree of System Order in the System of Systems (SoS) architecting process. Two highly desirable SoS attributes are the ability to withstand and recover from disruptions (resilience) and affordability. In practice, more resilient SoS architectures are less affordable and it is essential to balance the trade-offs between the two attributes. Ecological research analyzing long-surviving ecosystems (nature’s resilient SoS) using the Degree of System Order metric has found a unique balance of efficient and redundant interactions in their architecture. This balance implies that highly efficient ecosystems tend to be inflexible and vulnerable to perturbations while highly redundant ecosystems fail to utilize resources effectively for survival. Motivated by this unique architectural property of ecosystems, this study investigates the response to disruptions vs. affordability trade-space of a large number of feasible SoS architectures. Results indicate that the most favorable SoS architectures in this trade-space share a specific range of values of Degree of System Order. This suggests that Degree of System Order can be a key metric is engineered SoS development. Evaluating the Degree of System Order does not require detailed simulations and can, therefore, guide the early stage SoS design process towards more optimal SoS architectures.”

Research paper accepted to the Journal Reliability Engineering & System Safety
July 28, 2020
BiSSL PhD student Abheek Chatterjee just had his full length research paper accepted in the Journal Reliability Engineering &System Safety! The paper, titled “Mimicking Nature for Resilient Resource and Infrastructure Network Design,” investigates the use of ecological robustness – a functional characteristic of ecological food webs, to guide the design of a supply chain case study to improve it’s ability to survive network disturbances.
Abstract: “Increasingly prevalent extreme weather events have caused resilience to become an essential sustainable development component for resource and infrastructure networks. Existing resilience metrics require detailed knowledge of the system and potential disruptions, which is not available in the early design stage. The lack of quantitative tools to guide the early stages of design for resilience, forces engineers to rely on heuristics (use physical redundancy, localized capacity, etc.). This research asserts that the required quantitative guidelines can be developed using the architecting principles of biological ecosystems, which maintain a unique balance between pathway redundancy and efficiency, enabling them to be both productive under normal circumstances and survive disruptions. Ecologists quantify this network characteristic using the ecological fitness function. This paper presents the required reformulation required to enable the use of this metric in the design and analysis of resource and infrastructure networks with multiple distinct, but interdependent, interactions. The proposed framework is validated by comparing the resilience characteristics of two notional supply chain designs: one designed for minimum shipping cost and the other designed using the proposed bio-inspired framework. The results support using the proposed bio-inspired framework to guide designers in creating resilient and sustainable resource and infrastructure networks.”

May 22, 2020
BiSSL alumn Colton Brehm (MS graduate May 2020) just had his full length research paper accepted in the Journal of Industrial Ecology! The paper, titled “Nestedness in eco-industrial parks: exploring linkage distribution to promote sustainable industrial growth,” investigates the use of nestedness – a structural characteristic of ecological food webs, to guide the design of Eco-Industrial Parks (EIPs) to improve their sustainability, creating a more circular economy.
Abstract: “Eco-Industrial Parks (EIPs) have gained support as a solution that simultaneously reduces environmental burdens and promotes economic interests. EIPs operate under a mutualistic framework, where waste materials and energy are exchanged between industries to their mutual benefit, creating a diverse web of flows. Recent studies have focused on analogies between food webs (FWs) and EIPs, measuring a network’s success at ecological imitation as representative of its sustainability. Studies have focused heavily on the number of links and nodes in a network, but have neglected the economic reality that each investment comes at the opportunity cost of all alternatives. This analysis focuses on the nestedness metric as used by ecologists to address this pivotal facet to the FW-EIP analogy. Nestedness describes an ecological strategy for the position of links between nodes in a network in a way that maximizes network cycling for a given number of connections. This metric presents many advantages for EIP design and analysis, including maturity independence, size normalization, and a strong statistical record in highly mutualistic ecological systems. Application of nestedness to EIPs indicates a lower presence of nested structures and more randomness than what is typically seen in FWs. The industrial networks also display a correlation between high nestedness and internal cycles, suggesting that the reuse of materials and energy in EIPs can be improved upon by increasing the nestedness of structures.”

Journal of Cleaner Production Publication
January 7, 2020
Congratulations to BiSSL alumni Tirth Dave (MS graduate December 2019) on the publication of his paper in the Journal of Cleaner Production! “Designing ecologically-inspired robustness into a water distribution network” covers Tirth’s work on bio-inspired network design coupled with modeling of a water distribution network, showing that we can draw inspiration from nature to improve the resilience and reduce freshwater use in industrial resource networks.
ABSTRACT: Eco-Industrial Parks (EIPs), network of industries that collaborate by utilizing each other’s byproducts and wastes, are highly desirable for both the industries themselves, their environment, and governments due to their economic, environmental, and social advantages. Previous work has shown that EIPs are not as successful as they could be in terms of mimicking the behavior of biological ecosystems, highlighting that more work needs to be done for EIPs to truly mimic their biological-counterparts. The Kalundborg EIP, located in Kalundborg, Denmark, is a well documented example of an EIP with long-term success. Using the water network within the Kalundborg EIP as a case study, two bio-inspired networks are selected from an optimization based on the ecosystem metric robustness. The bio-inspired solutions are compared with a traditionally cost-minimized solution to understand what bio-inspired design can offer when a network is disturbed. Disturbances such as connection breakages and industry shutdowns are tested, showing that the bio-inspired designs require minimal recovery costs – in stark contrast to the traditional network solution. The results show that the bio-inspired designs reduce the network’s dependence on a scarce import (freshwater) and have higher overall network resilience in the event of disturbances. The three network solutions are discussed from a ecological perspective, explaining differences from the standpoint of ecosystem characteristics. The analysis highlights the benefits of using ecology to understand the nature of and improve the design of industrial networks.
ABSTRACT: Human networks and engineered systems are traditionally designed to maximize efficiency. Ecosystems on the other hand, achieve long-term robustness and sustainability by maintaining a unique balance between pathway efficiency and redundancy, measured in terms of the number of flow pathways available for a given unit of flow at any node in the network. Translating this flow-based ecosystem robustness into an engineering context supports the creation of new robust and sustainable design guidelines for engineered systems. Thermodynamic cycles provide good examples of human systems where simple and clearly defined modifications can be made to increase efficiency. Twenty-three variations on the Brayton and Rankine cycles are used to understand the relationship between design decisions that maximize a system’s efficient use of energy (measured by thermodynamic first law efficiency) and ecological measures of robustness and structural efficiency. The results reveal that thermodynamic efficiency and ecological pathway efficiency do not always correlate and that while on average modifications to increase energy efficiency reduce the robustness of the system, the engineering understanding of ecological network design presented here can enable decisions that are able to increase both energy efficiency and robustness.
Two BiSSL students, MS student Colton Brehm and PhD student Abheek Chatterjee, have had full papers accepted to 2020’s CIRP LCE conference!

J. Mike Walker Department of Mechanical Engineering Graduate Seminar
November 13, 2019
Honored to have been invited to give our department’s graduate seminar later today, I’m looking forward to it! Feel free to stop by if you’re around, I’ll be talking about my research regarding “Using biological inspiration to improve the design of complex human-engineered networks.”
Brief description: Biological ecosystems have been through millions of years of R&D, producing complex networks of interacting species that are able to support individual needs while maintaining system-level functions. In this talk Dr. Layton will show that these networks offer a relatively untapped source of design inspiration for improving the sustainability and resilience of our human engineered networks. Quantitative descriptors and analysis techniques are adapted from ecology through close collaboration with ecologists, enabling desirable ecosystem characteristics to be used as optimization guides for industrial resource networks (or eco-industrial parks, EIPs), water networks, supply chains, and power grids. Characteristics such as a high level of cycling of materials/energy within the system and a unique balance between redundant and efficient pathways are connected back to the achievement of traditional engineering goals such as cost and robustness.
So incredibly proud of all of our BiSSL research students! Last week’s fellowships and scholarships awards dinner for the J. Mike Walker Department of Mechanical Engineering was an honor to attend, to celebrate all of our department’s diverse and accomplished students!

Jewel Williams successful presented her 1st authored paper, with BiSSL undergrad Shelby Warrington as 2nd author, at the ASME International Manufacturing Science and Engineering Conference held in Erie, PA.
Abstract: Circular economy aims to address limited resources through the continuous circulation of materials and energy. Recirculating low quality materials for reuse is a sustainability goal that is analogous to the primary function of Nature’s detritus species, a keystone for the proper functioning of ecosystems. Prior applications of ecosystem structure to human network design uncovered that even the most economically successful networks of industries demonstrate a lack of analogous detritus actors in the form of reuse and recycling. The recycling industry’s volatile nature, dependency on international factors, and financial difficulties prevent this strategy from becoming an efficient alternative. Creativity in design, inspired by ecosystems, is proposed here as a method to repurpose manufacturing byproducts that are otherwise seen as low quality waste materials. Realizing the reuse potential of these materials can create detrital-type feedback loops, an attribute that supports the characteristic resilience and efficiency of ecosystems. The work here analyzes existing methods of pursuing circular economy and investigates the potential benefits generated by purposefully adding connects that create detrital-feedback-loops at the consumer and producer levels.

“Bio-inspired design for robust power grid networks”
by Varuneswara Panyam, Hao Huang, Katherine Davis, Astrid Layton
Technological advances have created a world where humans are highly dependent on an uninterrupted electric power supply, yet extreme weather events and deliberate attacks continue to disrupt power systems. Inherently robust ecological networks present a rich source of robust design guidelines for modern power grids. Analyses of ecosystem networks in literature suggest that this robustness is a consequence of a unique preference for redundant pathways over efficient ones. The structural similarity between these two system-types is exploited here through the application of ecological properties and analysis techniques to long-term power grid design. The level of biological similarity between these two system-types is quantitatively investigated and compared by computing ecological network metrics for a set of synthetic power systems and food webs. The comparison substantiates the use of the ecological robustness metric for optimizing the design of power grid networks. A bio-inspired optimization model is implemented, which restructures the synthetic power systems to mimic ecosystem robustness. The bio-inspired optimal networks are evaluated using N-1, N-2, and N-3 contingency analyses to assess system performance under the loss of 1, 2, and 3 components respectively. The bio-inspired grids all experienced significantly fewer violations in each loss scenario compared to traditional configurations, further supporting the application of the ecological robustness metric for power system robustness. The results provide insights into how ecological robustness can guide the design of power systems for improved infrastructural resilience to better survive disturbances.

BiSSL MS student Colton Brehm was a finalist for the Leo Award for best paper for his CIRP Life Cycle Engineering conference paper “Designing eco-industrial parks in a nested structure to mimic mutualistic ecological networks.”
Industrial Ecology uses ecological systems as a guide for improving the sustainability of complex industrial systems. Eco-Industrial Parks (EIPs) have gained support as a solution that seeks to simultaneously reduce environmental burdens and promote economic interests by exchanging materials and energy between industries to their mutual benefit. Recent studies have focused on drawing relations between food webs (FWs) and EIPs to improve the sustainability of the latter using ecological metrics, such as the level of cycling or average connections between actors. This study incorporates a new ecological metric, nestedness, into the discussion of sustainable design for EIPs. The association of nestedness with mutualistic ecological networks supports its application to EIP design. The work here improves the understanding of holistic network structure with the goal of improving future design decisions for EIPs with purposeful placement of material and energy flows.

Varuneswara Panyam and Astrid Layton, “Bio-inspired modeling approaches for human networks with link dissipation”
Structural similarities between human networks and biological ecosystems have inspired biomimetic design of human networks. The approach requires the networks to be represented as graphs, where the actors are nodes and the connections between actors are links. A major oversight in the application of ecosystem-based modeling to human networks thus far has been in the selection of actors and links. Transfers between species in a biological ecosystem are direct, happening when the species are co-located. Human networks often require a physical aid to complete the transaction, such as power transmission lines, pipelines, or vehicles. These exchange methods experience dissipation, which is not captured in current applications of ecosystem-based human network modeling. Human networks modeled as ecosystems thus far simply categorize exchanges as links in the graph, effectively forcing dissipation during material/energy transport to be neglected. This dissipation can sometimes be high relative to the total energy/material exchanged and thus is a potentially large oversight. Three hypothetical power grids and three Italian urban water distribution networks are used to quantify the impact of modeling interaction aids — power lines and water pipelines — as actors (and thus including any dissipation) in an ecosystem model. Ecological structural and flow metrics previously applied to human networks are evaluated between the two modeling methods. The comparison shows that the impact of this overlooked aspect is potentially significant and warrants consideration.
Abheek Chatterjee and Astrid Layton, “Bio-Inspired Human Network Design: Multi-Currency Robustness Metric Formulation Inspired By Ecological Network Analysis”
The Ecological Network Analysis (ENA) metric ecological robustness quantifies the unique balance that biological food webs have between their pathway efficiency and redundancy, enabling them to maximize their robustness to system disturbances. This robustness is a potentially desirable quality for human systems to mimic. Modeling the interactions between actors in human networks as predator-prey type exchanges (of a medium or currency rather than caloric exchanges) enables an ENA analysis. ENA has been shown to be a useful tool in improving the design of human networks because it allows the characteristics of biological networks to be mimicked. The application of these metrics is, however, limited to networks with only one flow type. Human networks are composed of many different types of flow interactions and thus a biologically-inspired indicator of total system robustness must take into account all of these interactions. This work further develops the traditional ENA ecological robustness metric to accommodate various flows between actors in multi-currency human networks. Two novel methods for quantifying multi-currency flow network robustness are introduced. The mathematical derivation for these new metrics is presented. The water network for the Kalundborg Eco-Industrial Park (EIP) is used as a case study to determine benefits of the proposed robustness metrics. The results obtained using the single-currency robustness and the two multi-currency robustness metrics are compared using the case study. Based on the analysis of the results obtained at the system level, as well as at the sub-levels, both multi-currency metrics showed the ability to predict systems characteristics for the multi-currency Kalundborg EIP. While both of these are promising, more research regarding these metrics is needed in order to develop an elegant and comprehensive total system robustness metric.

BiSSL Ph.D. student Varuneswara Panyam will be giving a seminar presentation for the Energy and Power group in A&M’s Electrical & Computer Engineering department on November 26th at 3pm in ETB 1003.
The presentation will cover preliminary research from his Ph.D. on redesigning the modern power grid for robustness following principles from Nature’s ecosystems. All are welcome!
Abstract: Extreme events continue to show that current power grid configurations, designed for efficiency, are vulnerable to disturbances. Naturally robust ecological networks present a potential source of robust design guidelines for modern power grids. Ecosystems balance pathway efficiency with redundancy to achieve robust network structure. Structural similarities between these two system-types support the application of ecological properties and analysis techniques to power grid design. In the talk, I will discuss the analogy between the two systems and an optimization model that our group has created to reconfigure a power grid to mimic ecosystems’ robust behavior.
Bio: Varuneswara Panyam is a Ph.D. student in the Department of Mechanical Engineering at Texas A&M University. He received his Bachelor’s degree in Mechanical Engineering from Shiv Nadar University in 2016. His Ph.D. research is focused on bio-inspired design of power systems.

“The winning papers, as well as the ones that were nominated but were not selected, demonstrate research of high scientific quality and relevance on a wide spectrum of topics in the field of industrial ecology.”
The two prize‐winning papers successfully competed among 12 nominated papers, out of which four were written by a junior author or junior first author. The paper by Ivanova and colleagues (2016), the winner in the junior author category, with a study on household consumption, was in a close race with the paper by Layton and colleagues (2016) offering a study on data and organization of eco‐industrial parks (EIPs) and food webs (FWs).
The second best paper in the junior author category by Layton and colleagues (2016) is an excellent paper with original and novel contributions to research methods for more fundamental understanding of the characteristics of EIPs and FW mimicry. In particular, the study offers significant improvements in systematic analysis of metrics and data processing for a large data set of EIPs and FWs. The paper analyzes to what extent the IE metaphor is actually implemented in EIPs, and FW structures are compared with EIP structures. The paper concludes that EIPs are less complex that their ecological counterparts, and that EIPs still have a long way to go to meet the resilient and efficient properties of natural systems. This is a valuable contribution to IE research: It improves the scientific links between ecology methods and IE methods and offers a basis for better ecosystem mimicry in circular economy initiatives. The study represents great value for the IE community and increases our understanding of the extent our metaphor actually holds. It is also valuable in terms of the data provided and analysis made of the current EIP structures. The paper is well written with proper illustrations, an excellent structure, layout and language, and with extensive data and documentation including supporting information.

In nature, networks have evolved where animals and plants interact and use efficient methods to best utilize resources. Dr. Astrid Layton, assistant professor in the Department of Mechanical Engineering at Texas A&M University, is researching whether companies can apply a similar concept of how this natural network looks and behaves in an effort to create more sustainable networks of industries. … read more

“The ENGAGE Summer Camp is a six-day residential summer camp designed for students from underrepresented groups who are strong in science, technology, and mathematics. The camp gives students hands-on, memorable experiences while inspiring them to consider a career in engineering.
During the camp, students stay on campus in residence halls, engage in discussions with student and faculty panels, visit engineering laboratories and research centers and work on engineering projects. Current engineering students serve as camp counselors and are with camp participants throughout the entirety of the summer camp.”
