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, …

Computational Investigation on Performance of Rib Roughened Channel
Abstract: ABSTRACT: Improving the heat transfer efficiency of machinery is crucial since it can result in savings on energy, materials, and expenses. Rib-roughening on the heated plane is one method of increasing rate of heat transfer. Rib roughened surfaces are utilized in various industrial applications. Rib roughened surface disturbs the laminar sub-layer and increases the turbulence. Because of increase of turbulence and mixing, rate of heat transfer is improved. Pressure loss …

INFLUENCE OF CONSTANT AND VARIABLE PASTERNAK FOUNDATIONS ON DAMPED SIMPLY SUPPORTED BERNOULLI-EULER BEAM UNDER MOVING LOADS
Abstract: This study presents an analytical investigation of the dynamic behavior of a simply supported uniform Bernoulli-Euler beam resting on both constant and variable Pasternak foundations subjected to concentrated moving load with damping. The governing equations of motion were formulated by incorporating the effects of foundation stiffness, shear interaction, damping, and load inertia. Analytical solutions were obtained for both moving-force and moving-mass problems. For the constant foundation case, the Generalized Finite …

PORTABLE SOLAR WATER HEATER
Abstract: This project explores the design of a portable solar water heater optimized for high-efficiency heat transfer in off-grid settings. The system utilizes the superior thermal conductivity of copper turnings, which serve as a heat exchanger to capture direct solar radiation. Using a closed-loop mechanism, a small pump circulates water from a storage tank through these copper coils, where it is rapidly heated before returning to the reservoir. This active circulation …

Investigating the Effects of Severe Plastic Deformation on Aluminium Alloy Properties: A Comparative Study
Abstract: Equal channel angular pressing is a metal forming process. It serves as a strengthening treatment through which ductile metals can be processed to refine their grain and subgrain structure. This process improves the mechanical performance of metals, including tensile strength, stress-controlled fatigue strength, and resistance to fatigue crack propagation. Equal channel angular pressing is one of the severe plastic deformation methods employed to produce ultrafine-grained materials. In this method, a …

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 …

Generative Lightweighting of Actuator-Integrated Robotic Structures Under Decentralized Additive Manufacturing Constraints
Abstract: This study presents the implementation and structural validation of a constraint-driven generative design methodology for the development of lightweight actuator-integrated robotic components fabricated using decentralized additive manufacturing. Building upon a previously formalized constraint-driven framework, the method was applied to the synthesis of a modular robotic link representative of actuator-integrated structural elements commonly used in legged robotic systems. The baseline component was defined to preserve critical functional interfaces, including actuator mounting …

Development of an Automated Load-Controlled Thermopower Measurement Technique for Thermoelectric Materials
Abstract: The Seebeck coefficient, or thermoelectric power, is crucial. In order to deliver accurate readings over a wide temperature range, a load-based, high-precision thermoelectric power (TEP) measurement device has been designed, constructed, and experimentally validated in this study. The system is based on a differential DC approach and replaces conventional spring-based contact mechanisms with a shifting mechanical load to avoid errors caused by spring contraction, thermal cycling, and contact instability at …
