A Computational Framework To Optimize Piezoelectric Power Harvesting From A Uav Wing, Hassan Koko, Gihad Ibrahim

Journal of Aviation Technology and Engineering

This paper proposes a computational framework to optimize the ambient power harvesting from an unmanned air vehicle wing by means of piezoelectricity. First, the wing shape and material are selected based on specific design factors. The wing is then subjected to a vibrational analysis in order to predict the first torsional frequency required to calculate an optimum charging speed. The harvester module is then selected so that the vibration frequency of the charging speed fails within the resonance frequency of the harvester. A finite element modeling is conducted to predict the harvester output voltage during the chagrining speed. Finally, a …

Where To Build Food Banks: A Machine Learning Approach, Gavin Ruan

The Journal of Purdue Undergraduate Research

Over 44 million Americans currently suffer from food insecurity, of whom 13 million are children. Food insecurity has been shown to cause a wide range of both physical and developmental issues. Across the United States, thousands of food banks and pantries serve as vital sources of food and other forms of aid for food-insecure families. By optimizing food bank locations, food banks and their resources would become more accessible to families who desperately require it. The aim of this paper is to build a machine learning framework that is able to optimize food bank locations and to consider factors such …

Security At Too High An Environmental Cost?: The European Union's Energy Independence Strategy And Its Environmental Implications For Air Quality In Poland And Hungary, Stephanie P. Peterson

The Journal of Purdue Undergraduate Research

After Russia’s invasion of Ukraine in 2022, the European Union worked to secure liquified natural gas (LNG) deals with third countries to abolish its dependence on Russian gas. In this article, I sought to determine the environmental implications of the European Union’s new LNG deals on the air quality in Hungary and Poland, two former communist states. Despite LNG being a cleaner fossil fuel, I hypothesized that it posed a threat to Hungary’s and Poland’s air quality as both countries endured rapid industrialization under Soviet control that forwent environmental protections. To prove this, I used qualitative data from before the …

Predictive Maintenance Analysis Of Turbofan Engine Sensor Data, Stanley A. Melkumian

The Journal of Purdue Undergraduate Research

Predictive maintenance in aviation and aerospace applications is among the most explored problems in machine learning (ML) and artificial intelligence (AI), and datasets such as NASA’s C-MAPPS turbofan engine degradation simulation data have proven invaluable, helping researchers explore numerous questions on engine performance, maintenance, and failure.

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 …

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. Prairies typically contain deep-rooted grasses, while agricultural lands contain shallow-rooted row crops. Root depth is considered a major control on …

And You Don't Seem To Understand: Disanalogies Between Artificial And Biological Consciousness, Derek Freeman

The Journal of Purdue Undergraduate Research

This paper posits a new way of attempting to formulate theories of machine consciousness. At present, inquiry revolves around formulating criteria that could be applied to machines to determine if they possess human-like consciousness. The paper demonstrates that efforts so far have not been fruitful, instead finding that present methods of inquiry are destined to result in an impasse between those who support the notion of machine consciousness and those who oppose it. Consequently, the paper questions the assumption that human and machine consciousness must resemble each other. It explores a different approach, one that rejects the idea that the …

Technological Accessibility For Wildlife Telemetry Research, Andrew Danielson

The Journal of Purdue Undergraduate Research

Over the course of two years, I conducted original research into improving accessibility for researchers in the field of wildlife telemetry. Wildlife telemetry is a technique used by biologists to track wildlife in the field, which requires the biologist to attach a small radio transmitter to an animal, usually using a specially designed collar, harness, or another means. These transmitters are battery powered and will emit or transmit a regularly timed radio signal that can be received by radio receivers carried by the researchers. Two issues faced by wildlife telemetry researchers are the cost of wildlife telemetry equipment and the …

Marvelous Bodies: Italy's New Migrant Cinema, Vetri Nathan

Purdue Studies in Romance Literatures

Historically a source of emigrants to Northern Europe and the New World, Italy has rapidly become a preferred destination for immigrants from the global South. Life in the land of la dolce vita has not seemed so sweet recently, as Italy struggles with the cultural challenges caused by this surge in immigration. Marvelous Bodies by Vetri Nathan explores thirteen key full-length Italian films released between 1990 and 2010 that treat this remarkable moment of cultural role reversal through a plurality of styles. In it, Nathan argues that Italy sees itself as the quintessential internal Other of Western Europe, and that …

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 …

How Many Annunciations Are There? Using European Prints To Digitally Explore The Iconographic Style Of Eighteenth-Century Portuguese Azulejos, Rosário S. Carvalho

Artl@s Bulletin

The combination of a computational approach with the expertise of art historians in studying the similarities and differences between European prints and eighteenth-century Portuguese azulejos has led to the emergence of an “iconographic style,” which introduced two major modes of depicting the Annunciation during the period under analysis. The article aims to assess the impact of the circulation of European prints on Portuguese tile coverings to better understand how the images were circulated and to determine their influence in terms of form, style, decoration, iconography and working process on the definition and execution of different iconographic programmes.

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.

Manufacturing National Boundaries? The Notion Of Style Between Identity Constructions And Spatial Approaches, Michela Passini

Artl@s Bulletin

Art historians have long been preoccupied by art’s geographical inscription. But it was during the interwar period that research on the geography of art really took off and was recognized as a field of study in its own right. This is evidenced by the organization of an international congress of art history (Stockholm, September 1933) specifically devoted to art geography.

What was the field covered in 1933 by artistic geography? How did it define its objects? And how an art history marked at the time by an extremely present methodological nationalism did shape geographical approaches?

The Inner Form Of Style: On Heinrich Wölfflin’S “Tactical” Formalism, Rémi Mermet

Artl@s Bulletin

In this article, I examine the enduring relevance of Heinrich Wölfflin’s approach to style, in light of the renewed interest in it among “postformalist” art historians. By delving into the theoretical foundations of the Principles of Art History, I explore Wölfflin’s Goethean interpretation of Kantian epistemology, revealing a conception of style characterized by its dynamic and symbolic “inner form” rather than mere static formalism. This analysis not only highlights affinities with Max Weber’s thought but also uncovers a previously overlooked connection to Wilhelm von Humboldt, offering valuable insights for current discussions on style.

Restorative Pedagogy To Build Community In The Classroom: Autoethnographic Reflections From Faculty, Sheila M. Mcmahon, Zahra Ahmed, Michelle Bemiller

International Journal of Teaching and Learning in Higher Education

Restorative justice (RJ) is a philosophy and set of practices that center harms and needs. Within a classroom setting, an RJ pedagogical approach invites a process of shared learning that attends to critical issues of equity, power, and voice. Utilizing an autoethnographic approach, this manuscript includes critical reflections from three faculty members from diverse disciplines and positionalities about the use of RJ approaches to teaching in our respective classrooms. This paper includes discussion about the intersection of RJ with critical pedagogy, power differentials, and pragmatic issues of classroom structure learning design.
