Optimization Of Tps Films Using An Adaptive Design Of Experiments Approach In A Bayesian Optimization Framework, Theresa Marks, Gracie White, Scott Lohman, Mayank Malhotra

The Journal of Purdue Undergraduate Research

Plastic pollution, amounting to 12 million tons annually, necessitates sustainable alternatives to single-use plastics. Compostable thermoplastic starch (TPS) films show promise but lack strength and durability compared to traditional plastics. This study employs an adaptive design of experiments (DoE) approach to enhance TPS films by optimizing testing points. The research focuses on varying concentrations of plasticizers (acetic acid and glycerol) in a water and potato starch mixture, aiming to identify the optimal ratio maximizing tensile strength and % elongation at break. Gaussian process regression (GPR) with uncertainty estimation and Bayesian optimization (BO) utilizing an acquisition function (AF) are employed. The …

Identification Of Conserved Eukaryotic Gene Products In Novel Mycobacteriophage, Brandon Mar, Jade Coxon, Lily Esterline, Sydney Clifford, Gabriella Burke, Mallory Motz, Alaina Gartner, Kioni Bush, James Lin, Lizzie Adams, Sophia Palant

The Journal of Purdue Undergraduate Research

Bacteriophage, a type of virus that infects bacteria, was discovered 100 years ago, initially isolated with a plaque assay in the 1940s. A mycobacteriophage is a subtype of bacteriophage that specifically infects mycobacteria. Since the introduction of DNA technologies and efforts to identify a plethora of bacteriophages, over 10,000 bacteriophages have been identified with 1,500 sequenced. Bacteriophage discovery has aided in genetic editing techniques, the development of synthetic biology tools, and disease treatment. However, to be able to expand on these capabilities, there is a need to identify more bacteriophages and sequence the genomes of these viruses, as they outnumber …

The Influence Of Soil Properties And Land Management On Soil Porewater Chemistry, Bethany Kettleborough

The Journal of Purdue Undergraduate Research

Soil water dynamics influence vegetation health, soil geochemical reactions, and stream chemistry. Water dynamics can be controlled by soil type and land management. It is important to understand water movement due to its influence on soil weathering, microbial activity, and nutrient transport. Water movement can be investigated using water stable isotope variability as a tracer. The purpose of this ongoing study was to analyze stable isotopes and dissolved ions in prairie and agricultural land management sites in Nebraska and Illinois.

Leveraging Social Ties To Financial Gains: Exploring The Impact Of Social Capital In Rural Development, Mallory L. Rahe, Andrew J. Van Leuven, Trey Malone

Department of Agricultural Economics Faculty Publications

Social capital, defined as networks of individuals linked through bonding or bridging relationships, plays a crucial but poorly conceptualized role in place-based development. The word “capital” implies an underlying value of the social connections throughout a community, and this study explores how these social relationships are used to initiate, plan, access financial capital, and implement economic development projects in rural areas. We avoid county-level aggregation bias and use a divergent pathway case study of projects across eight communities to examine how social ties are used during rural development in places with both high and low financial capital. Both types of …

The Computational Eye. Deconstructing Style In Digital Art History, Paul Guhennec, Ellen Charlesworth

Artl@s Bulletin

With the aim of grounding digital methods in the art historic tradition, this paper uses the discussions around style as a springboard to ask how digital art history can extend beyond providing quantitative confirmation of known trends to enrich our current understanding of visual cultures. Drawing from the examples throughout this issue, we explore how an analysis of computational ways of seeing—or the ‘computational eye’—can expose the underlying preoccupations and priorities of our own research.

Afin de mieux ancrer les méthodes numériques dans la tradition de l’histoire de l’art, cet article se sert des discussions récentes autour du concept de …

No Need Of Styles: Building Up Architectural Historiography, Carmen Popescu

Artl@s Bulletin

If styles lost impetus within the methodology of art historiography, in the (parallel) field of architecture, they were firmly rejected one century ago. One might consider that this more radical positioning (particularly in terms of epistemological tools) constituted the very reason for the undeclared but yet consumed divorce between the two disciplines. Attempting to define its specificity but also the autonomy of the discipline, architectural historiography followed a path less directly preoccupied with aesthetics and closer to functionality and technicity. My paper analyses how architectural historiography built up its idiosyncrasy.

Fostering Active Learning And Metacognitive Skills In A Cognitive-Science Based Math Course, Sheila Tabanli

International Journal of Teaching and Learning in Higher Education

There is a large body of research on how to improve student learning through active learning and metacognition. However, without well-structured guidelines, students do not tend to actively engage with the taught material, peers, and the instructor at a desirable metacognitive level (Deslauriers et al., 2019). To address this problem, a research-driven assessment structure is integrated into a nontraditional course called “Methods for Mathematical Problem Solving” (M2PS). Methods for Mathematical Problem Solving was designed by the author to teach students effective study principles stemming from cognitive science. The assessments include synchronous check for understanding (CFU) assignments to further investigate the …
