Chemical agents, unlike biological agents such as bacteria or viruses, include toxic chemicals that cause adverse effects death, temporary incapacitation, permanent harm to humans animals. These are structurally and functionally diverse, leading a wide range of possible dangers. However, federal threat assessments over the years have deemed chemical lesser than agents. This, in turn, has led De...

The accuracy of stockpile estimations is immense criticality to process optimisation and overall financial decision making within manufacturing operations. Despite well-established correlations between inventory management profitability, safe deployment measurement inspection activities remain challenging labour-intensive. This perhaps owing a combination size, shape irregularity as well the he...

In this article we consider how to construct schedules for the stacking and reclaiming activities of high-throughput dry-bulk export terminals (DBET) that operate large machines called stacker-reclaimers (SR) handle iron ore, coking coal thermal export. with persistent stockpiles, ever-changing geometry stockpiles can impose challenging scheduling constraints. For those situations, propose each...

introduction due to the proximity to the sea, beaches always attracted tourists. on the other hand the coastal ecosystems are the most important and sensitive dual nature (land, naval), and variety of animal species are within themselves. the most important (and also longest) coastal area in iran are persian gulf and gulf of oman in south with about 2530km long and caspian sea in north with abo...

Abstract The software for processing the photogrammetry is increasingly capable of producing a high-quality 3D model DEM, DSM, and DTM from an aerial photo measuring volume material. Nowadays, UAV technology has been rapidly used stockpile calculation mining construction industry. purpose this study to compare image using three different with conventional method GPS as reference. result obtaine...

Despite drones being successfully utilized for monitoring and detecting hazards in mines, there is limited research on their application open-pit stockpile volumetric computation compared to traditional methods. Furthermore, time, cost, safety have challenged the use of approach. Present study aims fill gaps by conducting a comparative analysis utilizing drone A mapping framework proposed guide...

At the request of the U.S. Army Project Manager for Non-Stockpile Chemical Materiel, Sandia National Laboratories is developing a transportable system for destroying recovered, explosively configured, chemical warfare munitions. The system uses shaped charges to access the chemical agent and burster followed by chemical neutralization to destroy them. The entire process takes place inside a sea...
