Anomaly Detection In Heterogeneous IoT Systems: Leveraging Symbolic Encoding Of Performance Metrics For Anomaly Classification
Get PDFAnomaly detection in Internet of Things (IoT) systems has become an increasingly popular field of research as the number of IoT devices proliferate year over year. Recent research often relies on machine learning algorithms to classify sensor readings directly. However, this approach leads to solutions being non-portable and unable to be applied to varying IoT platform infrastructure, as they are trained with sensor data specific to one configuration. Moreover, sensors generate varying amounts of non-standard data which complicates model training and limits generalization. This research focuses on addressing these problems in three ways a) the creation of an IoT Testbed which is configurable and parameterizable for dataset generation, b) the usage of system performance metrics as the dataset for training the anomaly classifier which ensures a fixed dataset size, and c) the application of Symbolic Aggregate Approximation (SAX) to encode patterns in system performance metrics which allows our trained Long Short-Term Memory (LSTM) model to classify anomalies agnostic to the underlying system configuration. Our devised IoT Testbed provides a lightweight setup for data generation which directly reflects some of the most pertinent components of Industry 4.0 pipelines including a MQTT Broker, Apache Kafka, and Apache Cassandra. Additionally, our proposed solution provides improved portability over state-of-the-art models while standardizing the required training data. Results demonstrate the effectiveness of utilizing symbolized performance metrics as we were able to achieve accuracies of 95.87%, 87.33%, and 87.47% for three different IoT system configurations. The latter two accuracies represent the model’s ability to be generalized to datasets generated from differing system configurations
Effective And Sustainable Strategies For Federally Qualified Health Centers To Engage Young Adults
Get PDFFederally qualified health centers (FQHCs) are instrumental in providing top tier healthcare and other resources to underserved populations. Whether they administer services in house or refer patients to other providers, FQHCs aim to provide comprehensive primary and preventative care services to people of all ages. They offer a range of services, from doctor and dental appointments to mental health and substance abuse counseling, regardless of a patient’s insurance status. To receive funding, FQHCs must follow the regulations and quality standards set forth by groups like the Joint Commission on Accreditation of Healthcare Organizations (JCAHO) and the Health Resources and Services Administration (HRSA).
A variety of barriers prevent young adults (18-24), particularly from underserved communities, from accessing resources available at community health centers (CHCs). Encouraging more people to utilize the preventative care resources provided by community health centers will increase quality of life for underserved populations, reduce the future burden on the healthcare system, and allow CHCs to access more funding.
Strategies to reach this currently hard-to-reach population were developed through interviews with health educators, analysis of existing patient data, benchmarking FQHCs across the United States, and surveying the target population. Barriers to utilizing preventative care resources were collected and current patient outreach strategies were assessed. New strategies were proposed and evaluated by current patient educators at FQHCs. This research will outline a cohesive set of effective patient outreach strategies for FQHCs to increase their young adult patient base, particularly regarding preventative care
Can Leadership Classes Help Women in Construction Embrace Vulnerability Early in their Careers?
Get PDFThis study investigates how a vulnerability lesson, integrated into a construction management university course, impacts women’s comfort levels in showing vulnerability in their early careers. It also examines the perceptions of individuals on the subject of vulnerability prior to taking the class expressing societal norms in relation to vulnerability and leadership in relation to vulnerability. Pre- and post-surveys, utilizing the Likert scale and free responses, were used to gather data from students enrolled in a leadership-focused class at California Polytechnic State University, San Luis Obispo. Findings reveal that while vulnerability is seen as vital for leadership, gender challenges persist, shaped by societal norms and workplace cultures. Post-training, participants reported increased comfort with vulnerability, greater willingness to seek support, and enhanced confidence in leadership roles. Feedback was also collected on the addition of this subject to future course curriculums, revealing how necessary and important it is for students to be taught the subject as preparation for the industry. The study suggests avenues for further research, including expanding to recent college graduates and reaching a broader audience with the vulnerability class to promote inclusivity and gather diverse perspectives. This research contributes to advancing gender equity initiatives and fostering more inclusive workplace cultures within the construction industry
The Impact of DISC in Construction Dialogue
Get PDFPersonality tests look to categorize individuals based on their values, identity, psychological traits, and/or perspectives. The DISC (dominance, influential, steady, complaint) assessment is one of the major personality tests. Multiple industries like healthcare and sales have utilized DISC to foster better overall communication from work relations and positive success. Construction management (CM) is a similar industry with heavy emphasis on influence and focus. Utilizing DISC in the construction industry can achieve similar effects to the healthcare and sales industry. To analyze the potential effectiveness of DISC in the construction industry, a survey was distributed to one class of CM majors roleplaying three scenarios common in the industry. This survey will be taken before the two-hour class discussion about DISC along with the actual DISC personality test. The survey would be revisited after and re-answered now with the new knowledge of the DISC discussion along with a three-question reflection analyzing their perceived effectiveness and helpfulness of the DISC personality. Overall, most of the survey group perceived DISC as a helpful tool in navigating CM scenarios and would be a potential tool used in the future. The adoption of DISC in construction can foster better work environments, working relationships, and effective leadership
Skip The Grid: Delivering Power to The Navajo Nation
Get PDFSkip the Grid is a groundbreaking initiative designed to bring sustainable, off-grid power solutions to isolated communities facing significant challenges, such as the Navajo Nation. This collaborative effort involved an interdisciplinary team of California Polytechnic State University, San Luis Obispo (Cal Poly) SOLV Energy, and Heart of America (HOA). Due to the vast and dispersed nature of the reservation, a historical lack of government investment, and the severe impact of COVID-19 on the community, many homes are without electricity. This project aimed to address these issues by installing Goal Zero solar panels, battery systems, and lighting in 24 homes of families with school-aged children from the Central Consolidated School District in New Mexico. The primary goal was to enable students to participate in remote learning and use school computers for their studies and homework. The project not only had a transformative impact on the community by enhancing educational opportunities but also provided an invaluable hands-on learning experience for Cal Poly students. By integrating various disciplines, the initiative achieved a common objective and laid the groundwork for future improvements. This collaboration exemplifies how innovative solutions and educational partnerships can drive social change and improve the quality of life for underserved populations
SLO Newman Catholic Center - Holy Monument
Get PDFThe SLO Newman Catholic Center is a Catholic Church that serves the students of Cal Poly San Luis Obispo and Cuesta College. Around 300 students attend Catholic Mass every Sunday here. While searching for a Senior Project, I approached the Priest and Admin staff of this organization and asked if there was anything I could build for them. They informed me they were gifted this tile mosaic of the Lady of Guadalupe they wanted to showcase in their backyard. They asked me to design and build a holy monument that could exhibit this beautiful tile mosaic. After 6 months of active design development and planning, I designed a 4’ wide by 7’ tall structure that incorporated a black tile façade and earth-toned brick columns to present the tile mosaic. Scopes for this project included rebar, concrete, CMU, tile work, and brick laying. Once the architecture was complete, I estimated, scheduled, planned, and built this structure. This project turned out successful as the structure was neatly constructed and it showcases the beautiful tile mosaic. Through this design build project, I gained important experiences and lessons I will utilize in my future construction career

Engineering An Injectable Hydrogel With Self-Assembling 3D Vasculature
Get PDFThis research developed methods for culturing self-assembling capillaries in an injectable gel as a potential method for vascularizing tissue-on-a-chip models to mimic physiological drug delivery. Additionally, a mathematical model was developed as a tool for understanding nutrient delivery and comparison of potential delivery systems. Organs-on-a-chip provide novel platforms for studying biology and physiology in 3D, allow exploration of tissue engineering on a manageable scale, and serve as models for drug screening and drug-delivery testing.
Methods were first developed for co-culture of endothelial cells and fibroblasts (3T3s or HDFs) in 2D, evaluating culture time, seeding density and ratio of HUVECs and fibroblasts, and immunostaining with a HUVEC-specific marker. Cells formed large sheets with no signs of vessel formation in 2D; therefore, the setup was translated to 3D culture to further induce stress and release of angiogenetic factors, using fibrin gel to suspend cells in 3D. After 9 days of culture, HUVECs had extensive network formation with a high degree of complexity in the experimental cell ratios (especially with 5:1 HUVECs:HDFs). Therefore, these parameters can be used as a starting point for further development of vascularized tissue constructs. A mathematical model was also successfully developed to assess the impact of cell concentration, consumption, and mode of nutrient delivery on 3D cellular constructs which can be used to predict the spatial distribution of glucose over time. Although the model shows flow introduced through a device is sufficient to maintain nutrient levels for cell growth, developing perfusable capillaries is still a critical part of creating physiologically representative tissues
