Abstract: A system for tracking inventory inside a warehouse with put-away accuracy is provided. The system 100 includes unmanned aerial vehicle (UAV) 102 including image capturing device 102A, warehouse 104, inventory tracking unit 106, user device 108, cloud server 110, and network 112. The UAV 102 is configured to capture media contents of pre-defined space within the warehouse 104 using image capturing device 102A. The pre-defined space includes rack bays with unique rack bay identifier and inventory items stocked on rack bays with pallet identifier that is similar to corresponding unique rack bay identifier. The inventory tracking unit 106 determines inventory data including empty space, inventory mismatch, and inventory record by processing the media contents using machine learning models 106A-B. The inventory tracking unit 106 sends empty space alert and mismatch alert to user and transmits inventory data to cloud server 110 and user device 108 through network 112.

Abstract: A fluid stream has material selected from the group consisting of radioactive matter and metals removed from it. An example material to be removed is cesium ions. A silico-titanate composition have a mole ratio of Si:Ti of 0.01:1.7 is provided in the fluid stream. The material to be removed is them permitted to bind to the silico-titanate composition. The silico-titanate composition may include a metal dopant MD present in a mole ratio of MD:Ti up to 1.0. The silico-titanate may also be a cation M present in a mole ratio of M:Ti up to 2.0.
