Topside Ionospheric Tomography Exclusively Based on LEO POD GPS copyright Phases: Application to Autonomous LEO DCB Estimation

This paper presents a novel technique to estimate DCBs from GPS transmitters and Pet Harness receivers on-board Low Earth Orbit (LEO) satellites.The technique consists of obtaining the DCBs as residuals from the difference between the ionospheric combination of the code and the associated ionospheric delay.The ionospheric delay is computed with TOM

Effect of Carboxylic Functional Group Functionalized on Carbon Nanotubes Surface on the Removal of Lead from Water

The adsorption mechanism of the removal of lead from water by using carboxylic functional group (COOH) Accent Table functionalized on the surface of carbon nanotubes was investigated.Four independent variables including pH, CNTs dosage, contact time, and agitation speed were carried out to determine the influence of these parameters on the adsorpti
