Entropy-Based Damage Accumulation in Tribological Systems: A Comprehensive Review
Abstract: This paper reviews classical wear models and entropy-based degradation approaches used for predicting failure in tribological systems. Various wear models, thermodynamic frameworks, and applications of the Degradation Entropy Generation (DEG) theorem are discussed. Friction, which is the primary source of heat generation in tribological contacts, is responsible for material degradation through a variety of irreversible processes. While classical wear approaches have been widely used for wear prediction and life estimation, …

The Biomechanical Impact of Slipper Sole Compliance on Lumbar Spine Load: A Quantitative Analysis of Indoor Footwear Ergonomics
Abstract: Abstract The global shift toward remote work has significantly increased the duration of indoor footwear usage, yet the ergonomic standards for slippers remain critically under-researched compared to athletic or industrial footwear. While "high-compliance" or soft slippers are traditionally marketed for immediate comfort, excessive mechanical softness may lead to foot instability, altered gait kinetics, and subsequent compensatory stress on the lumbar spine. This study aims to quantify the correlation between varying …

From Stress to Serenity: Adaptive Living Spaces for the Modern Tech Workforce
Abstract: Modern I.T. professionals often work long, irregular hours, seated for extended periods while managing deadlines, virtual meetings, and continuous digital interruptions. As homes increasingly function as hybrid workplaces, most residential interiors remain ill-equipped for this dual role, characterized by compact layouts, standardized furniture, inadequate lighting, and a lack of spaces for psychological detachment. This research advocates for adaptive and human-centered interior environments that promote physical comfort, mental well-being, and flexible …
