This research involved investigating the deflection efficiency of Rotating Toroidal-Induced Dipole Field Systems for spacecraft radiation shielding, with a specific comparison to static magnetic fields. Numerical simulations model the trajectories of electrons, protons, and high-energy cosmic rays as they interact with a three-coil toroidal system, featuring an induced-dipole component that enhances dynamic shielding. Unlike static…

Proper techno-economic evaluation of hybrid electric powertrain commercial aircraft necessitates a holistic thermal engine model that captures the various behaviors contributing to the output of the overall study. This model needs to encompass not just the typical size, weight, and power characteristics, but also critical factors such as cost and reliability. This paper provides an…

Originating more than 70 years ago within the US Department of Defense, Failure Modes and Effects Analysis (FMEA) has become one of the most ubiquitous design risk assessment tools in use today. For many, FMEA has outstripped fault tree and other forms of design failure analysis as the primary tool. FMEA has become a standard…

Agile and Predictive-style approaches each have their own pros and cons, managing project requirements in different, often conflicting ways. Applying these styles independently to critical software systems can result in adverse effects. Agile-style requirements management, typically documented in Connextra-style User Stories, offers customers and stakeholders the flexibility to adapt requirements as projects evolve. The highly…

We propose an Organizational Health Assessment (OHA) framework inspired by brief mental health screening tools like the Patient HealthQuestionnaire-9 (PHQ-9) and Generalized AnxietyDisorder-7 (GAD-7). By conceptualizing organizations as complex adaptive systems, the OHA draws parallels between individual mental health and organizational functioning. We outline the framework’s theoretical foundations, components, and practical implications for research and…

The criticality of security management stems from the complexity of information systems and the high value of assets and services. The diversity in security management solutions makes organizations responsible for choosing an adequate solution and adapting it to their context. However, the complexity makes the implementation process vary further, complicating choices. Moreover, security management solutions…

A system engineering process is described for the development of a novel approach toward mitigating the image degrading effects of optical turbulence in a horizontal atmospheric path. The work concentrates on the early phases of the system engineering process involving advanced modeling and ray-tracing. The critical output products are a detailed system concept specification and…
