Design and Implementation of an Adaptive Dual-Axis Solar Tracking System with Dynamic Threshold Optimization for Enhanced Energy Harvesting
type: item
description: This study presents the design, implementation, and performance evaluation of a low-cost, adaptive dual-axis solar tracking system. The system utilizes an Arduino Uno microcontroller and an array of four Light Dependent Resistors (LDRs) to continuously orient a photovoltaic (PV) panel toward the maximum irradiance source. The core innovation lies in an adaptive control algorithm that dynamically adjusts sensitivity thresholds (tol) and response delays (dtime) based on real-time ambient light levels. This approach mitigates unnecessary actuator oscillations and enhances stability under transient cloud cover or variable illumination, a common limitation in fixed-threshold trackers. Experimental results, conducted over a full diurnal cycle, demonstrate a mean increase in output voltage of 26.5% compared to an equivalent fixed-tilt panel, with a peak performance gain of 30.3% at noon. The system's stepwise servo control and independent axis management further contribute to its mechanical reliability and reduced power consumption. With its emphasis on adaptive logic, cost-effectiveness, and robust performance, this system presents a viable solution for optimizing energy yield in small-scale and educational solar applications.

CFD-Based Analysis of Aerodynamic Drag Reduction in a Sedan Model Using Passive Flow Control Devices
type: item
description: Aerodynamic drag on passenger cars significantly affects fuel efficiency and performance. This study reviews and synthesizes both experimental and computational (CFD) investigations on passive flow control techniques for reducing drag in a generic sedan model. Various devices such as vortex generators, diffusers, spoilers, flaps, and boat-tails are examined. We reference published wind-tunnel tests and CFD simulations to quantify drag reduction. Key findings include the efficacy of small flaps (gurney flaps) in reducing drag by up to 67.7% and vortex generators achieving modest reductions (around 4-6% for typical sedan models). Spoilers and diffusers can yield reductions of about 5-10% under optimal conditions. Combined devices often produce greater benefits; for instance, one study predicts nearly 19% improvement using a boat-tail extension. Experimental wind-tunnel tests have largely confirmed CFD predictions of reduced drag and fuel savings. The passive devices work by delaying flow separation and filling the low-pressure wake behind the car, thereby lowering pressure drag. Even small changes in drag coefficient yield fuel savings (e.g. a 5% drag drop can save ~3% fuel). This comprehensive analysis highlights that well-designed passive modifications can significantly improve sedan aerodynamics and suggests directions for combined device use. Future work should integrate these insights into production vehicles and further correlate CFD with real-world experiments.

The Green Algorithm: Leveraging Artificial Intelligence for a Sustainable Research Paradigm
type: item
description: The contemporary scientific enterprise is situated at a critical nexus, tasked with accelerating innovation to address global sustainability crises while simultaneously minimizing its own ecological footprint. This paper investigates the transformative potential of Artificial Intelligence (AI) as a key enabling technology to resolve this tension. Through a systematic review of current academic and technical literature, we analyze the integration of AI tools across the research lifecycle. The findings reveal a tripartite contribution of AI to sustainable science: (1) enhancing the analytical capacity for processing vast, heterogeneous datasets, which is critical for complex environmental modeling and socioeconomic analysis; (2) optimizing resource allocation and automating workflows, thereby significantly reducing the energy, material, and temporal costs of research; and (3) accelerating the innovation cycle for sustainable technologies, from materials discovery to smart grid design. However, the study also critically examines the inherent challenges, including the substantial energy consumption of large-scale AI models, the risk of perpetuating systemic biases, and the imperatives of ethical governance. We conclude by arguing that the responsible integration of AI into scientific research necessitates a strategic framework that balances technological advancement with robust ethical oversight and a commitment to "Green AI" principles.

type: item
description: We conducted a preliminary study evaluating the seismic performance of reinforced concrete (RC) columns retrofitted with polyurea (STPU) and glass fiber reinforced polyurea (GFPU). Experimentally, we conducted quasi-static, pseudo-dynamic and shaking table tests of RC columns having both circular and rectangular cross-sectional geometries. The data shows that STPU and GFPU both improve the demand of RC columns seismic value rustled displacement, energy dissipation, ductility and reserve capacity. A finite element (FE) model was developed and calibrated using experimental data with reasonable correlation between numerical results and experimental outcomes. The FE model indicates the superiority of circular columns over rectangular ones in terms of performance because of their cross-sectional shape, which possesses continuous surface geometry. These results emphasize the advantages of hybrid STPU-GFRP reinforcing in terms of RC columns’ performance regarding seismic loads, alongside acknowledging the versatility in structural retrofitting construction.
