Abstract

A technology called an alcohol detection driver system is used to stop drunk driving by identifying alcohol in a motorist's breath or blood. This technology correctly measures the amount of alcohol a driver has in their system using sensors and algorithms, and it stops the car from starting if the amount is more than the legal limit. The number of fatal accidents and traffic fatalities caused by drinking could be greatly decreased thanks to this technology. The main focus of this project is to carry out the experiment in lowering the number of alcohol-related incidents on the road. Alcohol detection devices come in a variety of forms right now, including ignition interlocks, passive alcohol sensors, and in-car breathalyzers. Although these systems have reduced the number of drunk driving accidents, there remain questions about their efficiency, dependability, and cost. According to the sensor's specs, the output voltage of the MQ-3 sensor reduces by 69% during the sensor's recovery period of 30 seconds at 69% of baseline resistance. To assess the long-term viability and efficiency of these systems in lowering alcohol-related accidents and enhancing traffic safety, more research is required.

Abstract

The construction sector is a major contributor to resource depletion and greenhouse gas emissions, underscoring the importance of adopting sustainable practices to meet environmental and climate goals. However, current assessments often underestimate impacts because of narrow system boundaries and insufficiently localized material inventory data, creating a critical research gap in accurately evaluating building sustainability. This study therefore applies to a comprehensive Life Cycle Assessment (LCA) framework to evaluate the environmental performance of key construction materials and to investigate strategies for integrating circular design and renewable energy to reduce carbon footprints. The results reveal that medium-term environmental impacts are approximately 20–30% higher than previously reported, while the Global Warming Potential of conventional brick increases by about 23% when additional life-cycle stages are considered. Furthermore, the analysis demonstrates that design-for-disassembly and recycling-oriented approaches can significantly enhance material recovery and reduce waste. These findings imply that developing harmonized, region-specific material databases and promoting circular construction alongside renewable energy integration are essential for improving LCA accuracy and achieving meaningful reductions in the environmental footprint of buildings.

Abstract

The aerodynamic performance of wind turbine blades plays a critical role in maximizing energy generation and overall system efficiency, making it a key consideration in modern renewable energy design. Despite extensive research on blade optimization, there remains a notable gap in understanding the combined effects of spoiler and winglet geometries, particularly their size and orientation on aerodynamic efficiency under low wind speed conditions. This study aims to address this gap by conducting a comprehensive numerical investigation into the influence of spoiler and winglet configurations on wind turbine performance. Computational Fluid Dynamics (CFD) simulations were performed using COMSOL Multiphysics, with the k-ε turbulence model employed to accurately capture turbulent flow behavior. A detailed parametric analysis was carried out, considering winglet height (4%–13% of blade radius), cant angle (20°–90°), twist angle (−2° to 12°), and tip speed ratio (0.02–1.12) at a wind velocity of 3 m/s. The results reveal that optimal combinations of spoiler and winglet parameters significantly enhance aerodynamic efficiency. The study identifies specific design ranges that maximize power output, achieving a peak aerodynamic power of 62.8 W. Although the addition of these aerodynamic devices increases the inertia of the turbine, the system performance improves, with an observed increase in output power of approximately 12%. These findings provide valuable insights for the design and optimization of wind turbine blades, particularly for low wind speed applications.
