    (Institute of Electrical and Electronics Engineers, 2014) Shafer, Brandon A.; Kriske, Jeffery E.; Kocaoglu, Omer P.; Turner, Timothy L.; Liu, Zhuolin; Lee, John J.; Miller, Donald T.; Department of Engineering Technology, School of Engineering and Technology
    Graphics processing units are increasingly being used for scientific computing for their powerful parallel processing abilities, and moderate price compared to super computers and computing grids. In this paper we have used a general purpose graphics processing unit to process adaptive-optics optical coherence tomography (AOOCT) images in real time. Increasing the processing speed of AOOCT is an essential step in moving the super high resolution technology closer to clinical viability.

    Ambient Temperature Control
    (2017-04-28) Maizama Gaya, Ayouba; Goodman, David
    This report is a summary of my senior design project. The project is called Ambient Temperature Control. This paper includes the parts and design of the project, how it is made and designed. It will also document all important stages of the project as well as any big changes that were made during the process. Consumers love great products with great quality but at the same time affordable. Modern thermostats can be very expensive and unaffordable for many of us. I decided to use to senior design project to create a temperature control device that will not break the bank. The device will read ambient temperature and based on a set point, a fan will turn on to keep that set point within a range. All this is possible by combining designed hardware, a built software and an interface to bring everything to life.

    Analysis of a Novel SPS Configuration Enabled by Lunar ISRU
    (2015) Schubert, Peter J.; Pinto, Sheylla Monteiro; Pires, Bruna Caroline; do Nascimento, Moises; Barks, Edward; Nderitu, Jonathan; Goncalves, Gabriel; Tokmo, Fatih; Department of Engineering Technology, School of Engineering and Technology
    Architectures for space-based solar power using in situ resource utilization (ISRU) of space materials can greatly reduce earth launch mass and can enable geometric capacity growth. These two factors allow the potential for low cost power generation after development of an in-space infrastructure. A collection of extraction and processing methods designed for lunar operation provides for large volumes of low cost solar panels. With abundant panels a novel configuration for solar power satellites (SPS) is possible which avoids many of the challenges of existing designs. The so-called "tin can" SPS has no moving parts. It includes integral thermal radiators. Station-keeping requirements are minimal. Structural integrity is designed-in so that balance of plant mass is minimal. In this work the architecture and infrastructure supporting the tin can SPS is developed to support rapid construction and deployment. Performance estimates for the SPS are provided regarding heat and energy balance, and specific mass requirements.

    Analysis of the Flow Performance of the Complex Cross-Section Module to Reduce the Sedimentation in a Combined Sewer Pipe
    (MDPI, 2020-11) Ji, Hyon Wook; Yoo, Sung Soo; Koo, Dan Daehyun; Kang, Jeong-Hee; Engineering Technology, School of Engineering and Technology
    The difference in the amount of stormwater and sewage in a combined sewer system is significantly large in areas where heavy rainfall is concentrated. This leads to a low water level and slow flow velocity inside the pipes, which causes sedimentation and odor on non-rainy days. A complex cross-section module increases the flow velocity by creating a small waterway inside the pipe for sewage to flow on non-rainy days. While considering Manning’s equation, we applied the principle where the flow velocity is proportional to two-thirds of the power of the hydraulic radius. The flow velocity of a circular pipe with a diameter of 450 mm and the corresponding complex cross-section module was analyzed by applying Manning’s equation and numerical modeling to show the effects of the complex cross-section module. The tractive force was compared based on a lab-scale experiment. When all conditions were identical except for the cross-sectional shape, the average flow velocity of the complex cross-section module was 14% higher while the size of the transported sand grains was up to 0.5 mm larger. This increase in flow velocity can be even higher if the roughness coefficient of aging pipes can be decreased.

    Annotation and Information Extraction of Consumer-Friendly Health Articles for Enhancing Laboratory Test Reporting
    (American Medical Informatics Association, 2024-01-11) He, Zhe; Tian, Shubo; Erdengasileng, Arslan; Hanna, Karim; Gong, Yang; Zhang, Zhan; Luo, Xiao; Lustria, Mia Liza A.; Engineering Technology, Purdue School of Engineering and Technology
    Viewing laboratory test results is patients' most frequent activity when accessing patient portals, but lab results can be very confusing for patients. Previous research has explored various ways to present lab results, but few have attempted to provide tailored information support based on individual patient's medical context. In this study, we collected and annotated interpretations of textual lab result in 251 health articles about laboratory tests from AHealthyMe.com. Then we evaluated transformer-based language models including BioBERT, ClinicalBERT, RoBERTa, and PubMedBERT for recognizing key terms and their types. Using BioPortal's term search API, we mapped the annotated terms to concepts in major controlled terminologies. Results showed that PubMedBERT achieved the best F1 on both strict and lenient matching criteria. SNOMED CT had the best coverage of the terms, followed by LOINC and ICD-10-CM. This work lays the foundation for enhancing the presentation of lab results in patient portals by providing patients with contextualized interpretations of their lab results and individualized question prompts that they can, in turn, refer to during physician consults.

    API’s & Machine Learning Principles For Fire Systems
    (2024-04-24) Felts, Joshua; Moe, Chris; Weissbach, Robert; Freije, Elizabeth; Pash, Phillip
    The FireConnect product line exists as a well-developed system for remote monitoring of fire protection systems with an extensive array of compatibility and iterations based on the controller manufacturers and their product lines, each with their own unique communication protocols. The FireConnect service provides the user with a unique interface for their monitoring service with access through a web-based browser or a dedicated mobile application. This product also collects and aggregates the same data on the service providers cloud-based servers, where we as the manufacturer can access this data via an API, or Application Programming Interface. This provides us, the manufacturer, with a plethora of data with an infinite amount of value, ripe with potential for monetization. The problem is nothing has been developed to make use of the data and its untapped potential outside of the real-time monitoring system unless an individual with extensive experience and industry knowledge were to examine the data trends. The goal of this project was to use the data in such a way to generate sales based on the logical use of this data and industry specific requirements for maintenance and testing, to provide automatically generated leads. These leads are to be automatically populated on a user interface, not to be confused with the existing product offering, but to be used by customer service or sales managers to proactively engage with customers, while simultaneously generating an email-based notification for the customer on file.

    Applying IPD Lean Principals to Healthcare Capital Projects
    (2020-07-28) Bastin, Brad
    Over the last 15-25 years, lean principals have evolved and been applied and promoted to the construction industry through organizations like the Lean Construction Institute (LCI). This project will demonstrate how these proven lean management principles and integrated project delivery (IPD) provide a successful alternative for delivering healthcare capital projects. In the right context, integrated project delivery and lean construction process can significantly benefit the healthcare construction industry. When planning lean projects, the project team must consider what tools and processes will be applied. The main drivers regarding lean and integrated project delivery are the owner's appetite for lean, project budget, stakeholder culture, and the project size. These variables will determine the level of lean intensity and process integration.

    Are Recent Terrorism Trends Reflected in Social Media?
    (IEEE, 2017-10) Terziyska, Ivana; Shah, Setu; Luo, Xiao; Engineering Technology, School of Engineering and Technology
    Social media plays an important role in shaping the beliefs and sentiments of an audience regarding an event. A comparison between public data sets that have holistic features and social media data set that include more user features would give insight into the spread of misinformation and aspects of events that are reflected in user behavior. In this research, we compare the trends identified in the public data set - Global Terrorism Database (GTD) with the trends reflected through the social media data obtained using the Twitter API. The unsupervised learning algorithm Self-Organizing Map (SOM) is used to identify the features and trends summarized by the clusters. The results show discrepancies in the features and related trends of terrorism events in the GTD data set and obtained Twitter data set to suggest some media bias and public perception on terrorism.

    Art, Architecture, and Community: Create Spaces to Highlight Local Talent
    (ASEE Peer, 2020-06-22) Nickolson, Darrell D.; Pruitt, Katie; Engineering Technology, School of Engineering and Technology
    The paper will focus on a two-semester service-learning project in which Architectural Technology Students are partnering with a local entity called Reclaiming Community. Reclaim is a subsidiary of a larger local organization with a mission to bring about sustainable regeneration, improvement, and management of the physical environment through their Art Shed initiative. Each semester will develop a separate set of shed designs, with separate assessment methods and outcomes. The over-arching goal of the project is revitalizing the neighborhoods that will house these sheds, and encourage the love of art and design in area. Sheds are designed with the intent that after a certain about of time in residence the materials will be recycled for custom designed furniture. Utilizing the evidence-based design process (EBD) students will collaborate with Reclaiming project organizers to identify goals for the destination points. Sheds are studied and designed utilizing varying roof styles and interactive design ideas. Through this process each student will design a version of the shed, creating detailed instruction manual with materials and construction methods, and do a miniature 3D study model of the shed. Community partners from the reclaim project will play an integral role in reviewing the design process of the sheds, giving critical feedback for revisions and use. This is a very important part to ensure the evidence basedesign strategies are effectively solving the design problem. Assessment methods include our institutions Start/Stop/Continue along with customized end of course survey specifically aligned with this project. The community partners will also assist in development of end of course surveys, further integrating them into the culture of the course. The Start/Stop/Continue assessment is a student-centered mid-semester assessment of the project and its process. The completed paper will include the assessment results and course/project modifications carried into the second part of the semester. The customized end of semester course survey will allow the community partner along with the faculty member to specifically target questions at the students participation in the project and the outcomes. Results will be used for phase two of the project to take place in the spring semester.
