Invited Biology Symposium Presentation

Atlanta, GA – January 5, 2025

We started the year off with our lab’s work being presented at the Society for Integrative and Comparative Biology (SICB, https://sicb.org/) 2025 conference, thanks to an invitation from Drs. Cassandra Donatelli and Karly Cohen to participate in their special session “From evolution to innovation: bridging biology and engineering through bioinspired design.” The presentation, and upcoming paper with PhD student Hadear Hassan, focused on how to better support engineers seeking to do bio-inspired design: “The Role of Information Representation in Fostering Bio-Inspired Designs in Engineering.” The presentation will be published as a paper in the ICB journal later this year.

Abstract: Engineering designs inspired by the natural world encompass many innovative and novel solutions to human problems, often solving problems where engineers had initially only seen trade-offs. Most bio-inspired engineering designs however have been the result of either chance observation or dedicated study, hindering efforts to have biological inspiration become a mainstream tool. Efforts have been made to develop normative bio-inspired processes and identify approaches that can aid the non-experts in biology find and successfully implement a bioinspired strategy, however true accessibility is still lacking. This work uses classroom studies to understand the impact of information representation on engineering design creativity under a biologically inspired engineering umbrella. Small teams of students were provided with a common problem description, followed by different sets of biological information. This biological information was made up of various technical levels of figures, discipline-specific terminology, and reading levels. The students were tasked with generating bio-inspired design solutions using the provided biological information. Sketches and feedbacks from students provide insight into a possible connection between information representation (text vs. images, reading level, disciplinary overlap, ideation novelty and diversity scores) and bio-inspired engineering designs. Using images and different levels of technical complexity in the text are possible routes for improving successful interdisciplinary knowledge transfer in ways that broaden the accessibility of problem driven interdisciplinary design.

Journal Paper on Circular Economy in Manufacturing Published in JMSE

Two BiSSL students, Ph.D. student Hadear Hassan and MS alumna Amira Bushagour, have coauthored a paper in ASME’s Journal of Manufacturing Science and Engineering. The paper, originally presented at the 2024 MSEC conference, focuses on useful overlaps between reconfigurable manufacturing and circular economy efforts by assessing the adaptability and connection to circular economy principles in 44 different manufacturing system configurations.

Reconfigurability in manufacturing signifies a system’s capacity to promptly adapt to evolving needs. This adaptability is critical for markets to maintain operations during unexpected disruptions, including weather anomalies, cyber-attacks, and physical obstructions. Concurrently, the concept of a circular economy is gaining popularity in manufacturing to mitigate waste and optimize resource utilization. Circular economy principles aim to reduce environmental impacts while maximizing economic benefits by emphasizing the reuse of goods and resource byproducts. The nexus between reconfigurability and the circular economy stems from their shared pursuit of sustainability and resilience. Interestingly, biological ecosystems also exhibit these traits, showcasing exceptional adaptability to disturbances alongside the ability to effectively utilize available resources during normal operations. This study explores various manufacturing system configurations to assess both their adaptability and connection to circular economy principles. 44 configurations are categorized based on layout (e.g., job shop, flow line, cellular) and analyzed using convertibility, cyclicity, and Degree of System Order metrics. A significant positive correlation (R2 = 0.655) is found between high convertibility and ecologically similar levels of structural cycling, suggesting that effective resource utilization supports adaptability in manufacturing systems. Furthermore, this paper proposes the existence of a possible “window of vitality” for cyclicity, as it demonstrates a significant correlation (R2 = 0.855) between the Degree of System Order and cyclicity. Identifying systems that strike a balance between redundancy, efficiency, convertibility, and cyclicity can aid manufacturing system designers and decision-makers in making choices that address increasing requirements for both sustainability and resilience.

2 New Cyber-Physical Power Systems Papers Published

Two new papers have been recently published from the BiSSL group first-authored and co-authored by its students resulting from a collaborative grant with Sandia National Lab and Dr. Kate Davis’ group in Electrical Engineering.

Highlights include:

1. A graph-embedding technique, Node2Vec, to capture neighborhood relationships with second-order biased random walks for risk assessment in cyber-physical power grids.
2. Highly realistic and synthetic cyber network topologies for power grids to perform our case studies.
3. Visualization of the risk assessment with various methods for a more comprehensive situational awareness for grid operators.

Modern power grids and other complex systems are a fusion of physical and cyber components, giving rise to intricate interdependencies. These interdependencies, however, also expose vulnerabilities that can be exploited by adversaries. This paper delves into the critical examination of these interconnections, inspired by Ecological Network Analysis (ENA) techniques. By drawing from ecological modeling, we aim to understand the role of cyber-physical interdependencies in the resilience of complex systems. We introduce various modeling methods, including bipartite and tripartite networks, to analyze and map these interdependencies in the context of the IEEE WSCC 9-bus and the ACTIV 200-bus case study. The paper explores how these models can identify key actors and assess network resilience. Through a detailed methodology, we apply ecological metrics and community identification techniques to comprehensively evaluate the system’s interactions. The findings offer insights into the interplay of cyber and physical elements in power grids and other complex systems. These analysis methods show that tripartite networks produce more information on indirect interactions within a complex network. Additionally, they provide detailed information on how disturbances could propagate in a cyber-physical power system. Denial of service scenarios for the WSCC 9-bus and the ACTIV 200-bus case studies are employed to support this conclusion.

This article explores vulnerabilities in modern power systems due to interdependencies between physical, cyber-physical, and cyber devices. Ecological Network Analysis (ENA) assists in constructing bipartite and tripartite networks for the WSCC 9-bus and ACTIV 200-bus systems. The findings reveal that tripartite networks offer deeper insights into indirect interactions, enhancing our understanding of systemic resilience under denial-of-service scenarios.

Abstract: Power systems are facing an increasing number of cyber incidents, potentially leading to damaging consequences to both physical and cyber aspects. However, the development of analytical methods for the study of large-scale power infrastructures as cyber-physical systems is still in its early stages. Drawing inspiration from machine-learning techniques, the authors introduce a method inspired by the principles of graph embedding that is tailored for quantitative risk assessment and the exploration of possible mitigation strategies of large-scale cyber-physical power systems. The primary advantage of the graph embedding approach lies in its ability to generate numerous random walks on a graph, simulating potential access paths. Meanwhile, it enables capturing high-dimensional structures in low-dimensional spaces, facilitating advanced machine-learning applications, and ensuring scalability and adaptability for comprehensive network analysis. By employing this graph embedding-based approach, the authors present a structured and methodical framework for risk assessment in cyber-physical systems. The proposed graph embedding-based risk analysis framework aims to provide a more insightful perspective on cyber-physical risk assessment and situation awareness for power systems. To validate and demonstrate its applicability, the method has been tested on two cyber-physical power system models: the Western System Coordinating Council (WSCC) 9-Bus System and the Illinois 200-Bus System, thereby showing its advantages in enhancing the accuracy of risk analysis and comprehensiveness of situational awareness.

Another Successful ASME IDETC Conference!

This year’s ASME IDETC-CIE conference saw one BiSSL Ph.D. student, Emily Payne, presenting her first-authored paper and Dr. Layton serving as an invited panelist for 2 panels.

Emily’s paper, “Integrating Machine Learning into the Design of Green Building Systems,” was presented in the SEIKM: Systems Engineering and Complex Systems.

Abstract: Sustainable infrastructure design is a complicated process often requiring detailed estimates specifications and constraints of the project scope to be compiled. Beyond the time-consuming gathering of project data sometimes the availability of completed projects is limited. Therefore, a method to produce similar designs with varied constraints requires a systems engineering perspective. Systems engineering provides a method to evaluate multidisciplinary design development while simultaneously following stakeholder requirements. Ecologically inspired systems have shown the ability to maintain balanced resources and structural relationships even under duress. Driven by the imperative to build sustainable infrastructure, this research explores the utilization of machine learning techniques to generate robust and reliable forecasts of green building specifications, even when design resources are scarce. To demonstrate the effectiveness of this approach, machine learning techniques were performed on a dataset of 93 green educational buildings, and on an oversampled dataset containing synthetically generated data points at the aim of certification level prediction. Both datasets contained metrics quantitatively characterizing cost, energy efficiency, and ecologically sustainable metrics specific to each building. Results indicate that the oversampled dataset allowed for better machine learning prediction among the classification algorithms considered. Oversampled data provided quality information offering cost minimization during initial design stages. This data suggests that oversampling is a reliable technique to amplify the design area of infrastructure projects when applied on data containing strong systemic classification patterns.

A panel session “Approaches to Environmental Sustainability, Perspectives from Europe and North America” hosted by the Design Society and organized by Dr. Julie Linsey invited me along with Dr. Abigail Clarke-Sather from the University of Minnesota Duluth and Dr. Devarajan Ramanujan from Aarhus University.

PhD Student Hadear Hassan Visits Portland, Oregon to Attend ASEE 2024

BiSSL Ph.D. student Hadear Hassan presented a collaborative paper in the Design in Engineering Education Division (DEED) for Student-Centered Approaches in Design Education titled “Engineering the Next Generation of Innovators: Analysis of Students’ Innovation Habits.” The paper was coauthored by BiSSL alumn Luis Rodriguez and collaborator Dr. Cynthia Hipwell.

In today’s rapidly evolving landscape, innovation is the cornerstone of high value creation. This fast pace necessitates a fundamental reevaluation of educational paradigms. The imperative to emphasize lifelong learning, inquisitiveness, innovation, and an unwavering commitment to continuous self-improvement is abundantly clear. At the heart of this educational recalibration lies two questions: To what extent can personal innovativeness be honed and amplified through curricular innovations? and What are the requisite strategies for nurturing students’ practical skills, thereby enabling a perpetual journey of discovery? This work is focused on the design of a course called “Innovation Mind and Skill Sets for Design and Research,” tailored specifically for students in the STEM disciplines. The class equips students with a comprehensive innovation-focused skill set, empowering them to synthesize their specialized knowledge within broader societal contexts and, in turn, navigate the complex terrain of breakthrough innovation. This paper delves into the course’s framework, which draws inspiration from the vast reservoir of innovation literature and two decades of the instructor’s industry experience applying and improving innovation business processes with her teams in a fast-paced, high-tech industry. The core hypothesis of this paper is that innovation is fundamentally a learning process, that personal innovativeness can be cultivated and elevated through the teaching of established principles derived from the realm of learning science. These principles encompass the elevation of metacognition, the deliberate integration of intentionality into the learning process, and the embedding of reflective practices into the students’ educational journeys. In addition, the curriculum integrates pedagogical principles related to systems thinking and Transformative Learning Theory for adults. The coursework is designed to impart practical techniques that serve as scaffolds for students’ innovation processes and enhances their metacognition. The journey through this educational framework leads to an ascent through the tiers of Bloom’s Taxonomy, guiding students to cultivate enduring habits that are essential for the sustenance of the innovation process. These practical skills are honed through active participation in a team project, revolving around the innovation process, with guidance and feedback from innovation practitioners. The learning experience is further enriched through a deliberate emphasis on reflection, integrated into classroom presentations. These aspects of student progress and improvement are assessed against traditional design curricula using the Innovator Mindset® Assessment. The results are analyzed to underscore the impact of curricular innovation in fostering and amplifying personal innovativeness.

BiSSL collaborator Dr. Julie Linsey was also in attendance and presented a poster in the NSF Grantees Poster Session on a paper coauthored by BiSSL MS student Pepito Thelly. “Board 358: Quantitative Network Analysis for Benchmarking and Improving Makerspaces.”

Makerspaces on university campuses have seen tremendous growth and investments in recent years. Growing empirical data demonstrates the significant learning benefits to engineering students. Makerspaces are a new tool in the engineering educators’ toolbox, and as such much more needs to be done to ensure these spaces effectively grow and meet their full potential. This grant has been developing a novel network analysis technique for makerspaces, to enable the underlying makerspace network structure to be understood in terms of its connection to the successful and impactful functioning of makerspaces. The work has uncovered some basic structural building blocks of makerspace networks, known as modules, and the tools and students that make up those modules. This network-level understanding of the space enables actions such as effectively removing previously undiscovered hurdles for students who are underutilizing spaces, guiding the design of an effective makerspace from the ground up at locations with fewer resources, and creating effective events or course components that introduce students to the space in such a way that increases their chances of returning. A deep understanding of the network structure that creates a successful makerspace also provides guidance to educators on things like the impact of adding particular learning opportunities through workshop or curriculum integration, and insight into the network-level impacts of the addition of new tools or staff. The work done over the past 3 years has tried to address the following key objectives: (1) Understand the role that network analysis can play in both understanding the connection between the structure and successful functioning of a makerspace. (2) Create design guidelines for both new makerspaces and the growth of existing makerspaces, derived from modularity analyses of two successful makerspace case studies. (3) Identify potential roadblocks that prevent students, especially underrepresented minority students, from feeling comfortable in and using makerspaces. Benefits of network analysis techniques include the ability to break down a seemingly complex and chaotic makerspace into actors interacting with tools. This data was obtained through short end-of-semester student surveys. Early work found that these end-of-semester surveys provide sufficient data for the proposed analyses and are comparable to survey information provided by students as they enter and exit the space.

Successful ASME 2024 MSEC Manufacturing Science & Engineering Conference

BiSSL Ph.D. student Hadear Hassan presented work at the annual ASME 2024 MSEC Manufacturing Science & Engineering Conference in Knoxville, TN. She presented two papers, both co-authored with BiSSL alum Amira Bushagour (who is now a Ph.D. student at Aarhus University in Denmark). One of the papers has already been selected for publication in the special issue of ASME’s Journal of Manufacturing Science and Engineering (JMSE).

Abstract: The circular economy (CE) is a resource system in which byproducts and traditional end-of-life resource flows are fed back into the system to reduce virgin resource use and waste production. Emerging technologies offer an exciting opportunity to support circular economy efforts, especially in the early design phase when opportunities for incorporating these technologies are relatively easy. Traditionally, however, the early design phase has access to very little data about resource flows which makes the introduction of new technologies difficult to do, especially with respect to market-related design decisions. In the later design stages, this data is easier to obtain but is met with increased inflexibility and costs that make these types of changes less common. This paper proposes the use of cyclicity, also known as spectral radius, and NS* minimal-data input metrics that can direct designers to options with the greatest theoretical impact on routing commonly wasted resources back into value circulation. Cyclicity is a metric commonly used in ecology to assess the existence and complexity of cycles, or material/energy pathways that can start and end at the same node, occurring in a system. The metric uses a topological adjacency matrix of resource flows between potential circular economy actors, modeled as a directional graph, and is calculated as the largest absolute eigenvalue of an adjacency matrix and can be a value of zero (no cycles), one (basic cycles), and any value larger than one (increasing presence and complexity of cycles). This study also evaluates actors making up the network as to whether they are part of a strong cycle, a weak component of a cycle, or are disconnected from a cycle, quantified with NS. In a strong cycle, all actors feed into the cycle and the cycle feeds back into the actors. Actors that are weakly connected to a cycle do not contribute to a cyclic pathway. Disconnected actors are not connected to any actor participating in cycling. This paper conducts two case studies on these design tools. The first, a survey of 51 eco-industrial parks (EIPs) and 38 ecological food webs to compare the presence and complexity of cycles in industrial resource systems to ecological resource systems. The latter, food webs, are very effective at retaining value inside the system boundaries. The former, EIPs, were built in support of circular economy principles to use waste streams from one industry as resource streams for others. The analysis shows that 46 out of 51 EIPs had cyclicity values of one or greater and an average of 54% of actors in an EIP are strong. The food webs all have a cyclicity greater than one and an average of 79% of actors in a food web are strong. These results can help decision makers consider CE-supporting pathways earlier in the design process, increasing the likelihood that emerging technologies are incorporated to maximize their CE impact. The second case study explores an emerging technology, Brine Miners, and how cyclicity and NS can be used to guide design decisions to impact the ability of this technology to aid in the creation of a circular economy. The exploration found that focusing on the creation of energy has the potential to add new actors to resource cycling and that diversifying the uses of byproducts creates more complex cycling within a hypothetical economy.
