Magnetic Actuation Chamber System (MACS)
No full textThe Magnetic Actuation Chamber System (MACS) is an innovative solution designed to enhance the cultivation of cells and tissues under simulated microgravity conditions using a 3D clinostat. By integrating a magnetic actuator with a microfluidic organ-on-chip platform, the system facilitates precise mechanical stimuli for tissue engineering and disease modeling. Key upgrades, including a pneumatic piston system, Raspberry Pi 4-based processing, and enhanced nutrient delivery through microfluidic pumps, significantly improve reliability, data collection, and adaptability. The system’s modular design ensures flexibility for future modifications. Initial results demonstrate the potential of MACS to replicate natural cellular environments, with plans to study heart and lung cell growth under simulated conditions. This research aims to explore cellular behavior in microgravity, with potential applications in cancer treatment and regenerative medicine. The MACS represents a critical advancement in biotechnological research, providing insights into cell growth mechanisms and supporting novel therapeutic discoveries
Finite Element-Based Physics Informed Neural Networks
Full text linkThis study builds on previous work developing Finite Element-based Physics-Informed Neural Networks (FE-PINNs), which combine the Finite Element (FE) method with Physics-Informed Neural Networks (PINNs) to solve inverse problems. In earlier research, we introduced the FE-PINN framework and demonstrated its effectiveness in performing parameter regression on simple structural models. In this work, we propose a temporally discrete variant, which extends the original method by discretizing the governing equations not only in space but also in time. We compare the performance of both frameworks --Continuous FE-PINN and Discrete FE-PINN -- under varying levels of noise, initialization errors, and available system measurements. Continuous FE-PINN achieved reliable convergence with up to 30\% initialization error and across all tested noise levels. In contrast, Discrete FE-PINN, while more computationally efficient, was sensitive to noise and performed reliably only in homogeneous media. Both methods required at least two measured degrees of freedom (DOFs) for accurate parameter estimation. Continuous FE-PINN is better suited for noisy environments, while Discrete FE-PINN is advantageous in noise-free settings with limited computational resources. These results provide a foundation for applying FE-PINNs to structural analysis and lay the groundwork for future extensions to more complex systems
A Review of Interventions that Support Thriving at Different Levels in Engineering Education Ecosystems
Full text linkThis paper explores approaches and interventions aimed at increasing engineering thriving in engineering education ecosystems at the Micro, Meso, and Macro levels. Engineering directly impacts the thriving of society and organizations, but the education of engineering students is not known for thriving (yet). This paper combines prior work on engineering thriving and complex systems science to identify currently published interventions at the Micro, Meso, and Macro levels. The systematic literature review includes 29 peer reviewed papers selected from 6 journals and 11 conference papers across three databases. Prior work on engineering thriving has largely focused on the Micro level (individual focus) and Meso level (organizations focus) with little focus on the Macro level (social institutions focus). The result of this work is two contributions. First, we provide an analysis of interventions that impact thriving at each of the three levels in the engineering education ecosystem. Second, we examine how interventions affect the influence and flows of thriving between levels. We frame these findings within the context of complex systems science and offer suggestions for future research, policy, and pedagogy. Overall, this work seeks to identify specific strategies and high-impact interventions to increase thriving across multiple levels of engineering education ecosystems
Effects of Respiratory Muscle Training and Nitrate Supplementation on Exercise Performance
Full text linkThis study will test the hypothesis that 6 weeks of respiratory muscle training (RMT) will increase diaphragm muscle thickness, power, and aerobic exercise performance and that these effects will be greater when RMT is combined with dietary nitrate supplementation. Utilizing the K5 PowerBreathe device for RMT, participants will complete a six-week training protocol while incorporating nitrate supplementation to assess its impact on respiratory muscle strength (Sindex) and endurance exercise performance (VO2max). Pre- and post-intervention measurements will include diaphragm thickness assessed via ultrasound, Sindex, lung volume, maximal cycling power output, and VO2 max. VO2 max and maximal cycling power will be determined through a step-ramp-step bike test utilizing pulmonary gas exchange measurements. This investigation explores how RMT and nitrate intake influence respiratory muscle function and may enhance athletic performance. The findings are anticipated to contribute to a deeper understanding of cardiorespiratory health and performance enhancement strategies, with potential applications for athlete, operational, and clinical populations
