This study investigates the enhancement in fresh water productivity of a double-slope solar desalination still when coupled with both tracking and non-tracking solar dish concentrators. The primary objective was to quantify the performance differential between the two concentrator types under clear-sky conditions and compare the maximum yields against conventional desalination. Experimental results demonstrated that the maximum daily and hourly fresh water outputs for the tracked concentrator system were 4,050 mL/d and 730 mL/h, respectively. In comparison, the non-tracking system achieved maximum outputs of 2,760 mL/d and 530 mL/h. The tracking system led to a significant overall increase in fresh water production, showing an improvement of 46% compared to the non-tracking configuration and a 100% increase when benchmarked against conventional desalination. The maximum energy consumed by the system utilizing the tracked concentrator was recorded at 23,113 kJ/day. The findings underscore the substantial advantage of solar tracking technology in maximizing the output of solar desalination stills, presenting a viable path toward increased efficiency in passive water purification systems.
The construction industry, with its complex projects and hazardous work environments, is inherently prone to safety risks. Despite efforts to mitigate these risks, incidents resulting in injuries, fatalities, and economic losses continue to occur. Traditional incident reporting methods are often limited by underreporting, delayed responses, and lack of real-time data, highlighting the need for more efficient, technology-driven solutions. To address this challenge, this study aims to develop an automated incident reporting system tailored to the construction industry’s specific needs. A questionnaire survey was conducted among 113 construction site professionals using Google Forms. The results showed that 75
Due to fossil fuel shortages and environmental concerns, alternative energy systems have been developed as an economic and environmentally beneficial alternative. The most potential alternative energy source is solar. Before commercialization, solar thermal systems must be more efficient and effective. Increased heat transfer rate and performance parameters are improved with nanofluids. Nanofluids are sophisticated liquid mixtures with nano-sized solid particles suspended. Aluminum Oxide (Al2O3) nanoparticles in water as nanofluids are used to test a Glass Fiber Reinforced Parabolic (GFRP) parabolic solar collector. Particle volume concentrations of 0.02, 0.06, and 0.09
Water is the most ubiquitous material in nature and most vital for domestic purposes such as drinking, cooking, washing, bathing, etc. Water treatment (WT) is currently among the major areas of research due to the depletion of water resources and fear mongering regarding environmental pollution, which has compelled the upgrading of conventional WT technology toward recycling and reuse. In this project we use the powder of neem leaf, dried banana peel, and guava leaf as coagulants to treat the greywater from the kitchen. This work provides information related to natural bio-coagulants such as neem leaf, dried banana peel, and guava leaf powder and their merits and limitations, outlines the performance of turbidity of greywater by adding different proportions of coagulants and highlights their efficiency of coagulation mechanism, turbidity removal, and color. Although chemical coagulants are efficient in WT, they are usually expensive, toxic, associated with health issues and non-sustainable. So the sustainable alternative is the use of natural coagulants such as neem leaf, dried banana peel, and guava leaf powder, which are readily available, economical, easy to use, biodegradable, non-toxic, eco-friendly, and effective. It could be concluded that the natural bio-coagulants have the ability to remove turbidity greatly in waste water, hence it has a great potential to replace chemical coagulants in greywater water treatment.
The construction industry is inherently high risk, with worker safety being a paramount concern. This project focuses on developing a real-time safety monitoring system for construction sites using vision-based techniques to enhance worker safety. The methodology begins by collecting diverse images and annotating each image with relevant safety elements. In the data pre-processing stage, image augmentation techniques such as rotation, scaling, and flipping enhance dataset diversity, improving the model’s robustness. Following augmentation, the images are normalized to standardize inputs for the YOLO algorithm. The dataset is then divided into training, validation, and test sets, ensuring a balanced distribution of scenarios for effective training and evaluation, ultimately facilitating accurate real-time monitoring. The model is trained on the annotated dataset. The mean Average Precision (mAP), Precision, and Recall are evaluated. The ultimate goal is to develop a system capable of accurately detecting safety risks, reducing accidents, and ensuring compliance with construction site safety standards.
