Capstone Review: Filament Unit Multiplexing Engine, Gal Cohen

University Honors Theses

The Filament Unit Multiplexing Engine (FUME) is a Mechanical Engineering capstone project sponsored by Portland State University's Electronic Prototyping Lab (EPL). The project addresses the need for an automated system to manage 3D printing operations. The current manual process of selecting and routing a spool of filament to one of the available 3D printers is labor-intensive and limits the efficiency of the lab's 3D printing farm. FUME aims to create a custom solution tailored for a multi-user, multi-spool, and multi-printer environment. The designed system includes key components: a spool holder, an engine, a track and shuttle system, and a funnel. …

Creating Content For Prison Design Course: Nordic Countries Vs. United States, Calvin Steven Clauson

Construction Management

Since 2010, prisons in Nordic countries have begun to take a very progressive approach to rehabilitating prisoners, addressing prisoners more humanely than is traditionally done in the United States. This project aims to develop course content that looks at the design elements of prisons in the United States and performs a comparative analysis with more progressive Nordic prison designs. Cal Poly’s construction management department will incorporate the developed content into one module of a co-taught course with sociology. The course will examine the ways social changes impact the construction of prisons and the social impacts of design and construction on …

Identifying Sick Cells From High-Resolution Solid-State Micropore Data, Abdul Hafeez, Azhar Ilyas, Ali R. Butt, Samir M. Iqbal

Mechanical Engineering Faculty Publications and Presentations

Early detection of diseases such as cancer can drastically improve prognosis and treatment. To this end, solid-state micropores can measure distinct mechanical properties of diseased cells from their translocation behavior — detected as pulses in the temporal data stream of ionic current — and help diagnose diseases at early stages. However, the obstacle in such approaches is that the accuracy of the sensor is affected by noise, making the pulse detection task too subjective. This is inefficient especially when the disease-relevant data is only a fraction of the total acquired data. Thus, it is important to intelligently automate the detection …

Neurocomputing And Interfacing Digital Tasting System: Research, Design, And Evaluation, Amira J. Zaylaa, Ahmad El Hajj

BAU Journal - Science and Technology

The continuous evolution in computing and interfacing has been extended to develop multi-sensory experiences in many domains such as neurological, auditory, vision, and haptic domains. So far, only a few remarkable system approaches have been approved to be serving the taste sensation digitally. Although taste sensation is linked to the brain, there is a lack of optimal neurocomputing digital taste sensation systems. Our study provides a new neurocomputing method to digitally stimulate the sense of taste by electrical stimulation on the human tongue. We aim to link chemical stimulation and electrical stimulation in order to design an electronic interface for …

A Study Of Biochar Production Via Continuous Vacuum-Assisted Pyrolysis, Max Wohlgenant

Graduate Theses & Non-Theses

The present study focuses upon the design, fabrication, and feasibility of the bulk production of scientific biochar for mobile delivery. In the 2022 annual report, the National Academies of Science, Engineering, and Medicine recommended the integration of mobile, decentralized reactors that employ flexible manufacturing and circular economic principles. Biochar production, involving the thermal degradation of biomass under an inert atmosphere to yield remediation media is an ideal material to satisfy this recommendation. Many potential application sites, such as abandoned mines, are remote and limit the construction of large infrastructure. The continuous vacuum-assisted pyrolysis (CVAP) reactor was designed to: increase biochar …

Exploring The Relationship Between Designing And Composing With An Analog Synthesizer, Felix Morrissey

Honors College

For my electrical engineering capstone, I designed and built a handheld analog synthesizer. This analog synthesizer is a musical instrument which uses electrical analog components to generate sounds with properties based on the user’s input. My goal when creating this device was to maximize its utility while remaining within the scope of the capstone project. After the synthesizer was built, I wrote and recorded several pieces of music which each utilized the synthesizer prominently. The aim of this process was to be able to explore the relationship between an instrument’s design and the quality of the music produced utilizing it. …

WWU Honors College Senior Projects

This project is a comprehensive overview of efforts made in the ENGD Makerspace to strengthen community, make the space welcoming and inclusive to all students, and combat techno-centric norms and stereotypes that keep people from learning and participating in makerspaces. It includes research conducted on WWU students’ feelings and experiences in the Makerspace, which found that women and non-Engineering-and-Design-major students have lower self-reported feelings of belonging and being part of the Makerspace, and concludes with proposals on how to continue work facilitating an inclusive environment and increasing sense of belonging and participation for women, trans students, and non-majors.

Architectural Hybrid (Physical-Digital) Prototyping In Design Processes With Digital Twin Technologies, Gulbahar Emir Isik, Henri Achten

Architecture and Planning Journal (APJ)

A digital twin is a simultaneous digital reflection of object processes and states. Digital twins are usually made of objects that exist in reality or which are very near completion in a design and production process. In our research, we investigate the potential of digital twin technology for early design. Key to the early application of digital twin in design is the role of information and simulation. Since design information is valuable for predicting the future of design, we assume that design will begin to change as digital twin technologies become more and more adaptable, as designers simultaneously have digital …

Building Artificial Reefs From Recycled Construction Materials: A Feasibility Study, Nicholas H. Lew

Construction Management

Naturally occurring reefs are some of the world’s most biologically diverse ecosystems formed by jagged rocks tucked slightly below sea level. In recent years global warming began to pose a major threat to many reef habitats. Most relevant is the increase in surface seawater temperatures that cause coral to bleach, taking away major food sources for larger marine species. Researchers have combated this by deploying artificial reefs in substitution for naturally formed limestone rock formations in order to promote the expansion of coastal habitats. This project specifically aims to utilize construction waste towards the production of artificial reefs, effectively upcycling …

Creativity, Craftsmanship, And Connection: Large-Format Sculpture Design, Jacqueline L. Puga, Gordon Hoople

The STEAM Journal

Artistry is a concept that is not usually explored in engineering yet is an invaluable skill that touches everything from product design to systems thinking. This past summer I developed conceptual designs for a large format sculpture that required connecting engineering knowledge with artistic vision. The initial phase required constant inspiration and creativity. The first step was to look at previous sculptures showcased throughout the world, such as at venues like “Burning Man,” to understand the possibilities or limitations of the space provided. Sketching varied and numerous ideas was essential in our design process. Next, we took our favorite ideas …
