“…UAS (Drones) provide an accurate, cost-effective, fast, and safe working distance suitable for volumetric computations in open pit quarries. These findings agree with (Farhadmanesh et al, 2021), (Hassandokht Mashhadi et al, 2022) who found that UAS are cost-effective and reliable technology for civil engineering applications. In addition, Ref (Zhou and Gheisari, 2018).…”

“…It also has great potential in disaster and road traffic monitoring (San et al, 2008); (Austin, 2010). Mashhadi (Hassandokht Mashhadi et al, 2022) investigated the feasibility of using Nebulizer-Retrofitted UAVs (DJI Agras MG-1S drone) in controlling air pollution and reducing heat stress at construction sites. The findings showed that the average wet bulb globe temperature decreases by 1.7 °during the flight phase compared to average values for the preflight and postflight phases.…”

Despite drones being successfully utilized for monitoring and detecting hazards in mines, there is limited research on their application for open-pit stockpile volumetric computation compared to traditional methods. Furthermore, time, cost, and safety have challenged the use of the traditional approach. Present study aims to fill the gaps by conducting a comparative analysis of stockpile volumetric computation utilizing a drone and traditional approach. A mapping framework is proposed to guide mine personnel on how to conduct open-pit stockpile volumetric computations. The methodology comprises using a drone and traditional survey approach to measure the volume of a known quarry stockpile. Drone-captured images are processed in Pix4D mapper software and geometric techniques are applied to the traditional survey approach. Findings show that the smaller the error of the checkpoints the more accurate the generated model making the measurements reliable. The generated Pix4D quality report showed a root mean square error of 0.019. The drone percentage error to the actual volume is 2.6% while the traditional approach is 1.3%. Both estimations are less than the maximum allowable percentage error of ± 3%. Therefore, compared to the traditional approach drone technology provides an accurate, cost-effective, fast, and safe working distance suitable for stockpile volumetric computations in open pit quarries.

“…Additionally, investigating the utilization of UAV sprayers on a large scale, such as in agriculture and construction applications, is crucial. In the construction sector, for example, conventional methods like water curing in cement-based materials (Harirchi and Yang, 2022),and reducing heat stress can be potentially improved through the use of UAVs (Hassandokht Mashhadi et al, 2022).…”

Highlights A comprehensive review of the current Unmanned Aerial Vehicle Sprayer in precision agriculture applications. Comparison of manned and unmanned aerial sprayers in precision agriculture. Latest developments of commercialized UAV sprayers available on the market. Abstract. Unmanned Aerial Vehicles (UAVs) are becoming more broadly used for improving agricultural spraying applications. However, compared with the nearly 100 years of data accumulated on manned aerial applications, UAV sprayers are relatively new, and associated technologies are in the early stages of development. The objective of this paper is to give a comprehensive review of the current UAV spraying platforms with a comparison to manned aerial sprayers and a discussion of their application, performance, and efficiency. A total of 213 peer-reviewed and non-peer-reviewed articles, extension papers, government websites, and company websites were reviewed and cited in this study. We also discuss factors that could influence the effectiveness of aerial spraying applications, such as release height, wind speed, vortex strength, and droplet size. Finally, we review the latest UAV sprayers available worldwide and present technology gaps in those platforms. We highlight areas that require improvement, particularly in autonomous navigational controllers and spraying systems. Keywords: Droplet distribution, Plant protection, Precision agriculture, Spot spraying, UAV sprayer.

“…Primarily, heat stress was observed using non-wearable devices and wearable devices. Researchers have used non-wearable devices to measure heat stress for a variety of purposes and these non-wearable devices are good indicators of environmental heat of workers (Hassandokht et al, 2022;Fang et al, 2021;Tang et al, 2021;Wan, Jia and Goh, 2021;Rasdan et al, 2020;Al-Bouwarthan et al 2019).…”

There is an escalating threat of heat stress exposure by all and those at a disproportionate risk are construction workers. Beyond this, roofers as a subset of those workers are second when it comes to the risk of heat-related deaths, but there are not many studies that specifically focus on the need to protect roofers. That is why it is imperative to further investigate the impact environmental heat has on roofers and this study begins to forward this work by understanding the physiological response of roofers to heat stress to advocate for more research in this area of work. To determine the conditions and physiological response to working in hot environments by roofers, the research team used two wearable devices to obtain environmental heat and core body temperature measures. What is found is that participants experienced significantly high heat index values while working. This is reflected in the measure of workers’ core body temperature readings that in some cases have shown core body temperatures significantly exceeding normal core body temperatures.
