It can be used in contexts where permission is granted to watch or monitor something.
Example: "The new policy will allow observing the process to ensure transparency and accountability."
Alternatives: "permit viewing" or "enable monitoring".
Radargrams acquired over Mars polar caps allow observing clear echoes up to kilometers depth.
The simulations allow observing the flow as it evolves from deep laminar (Re=0.1) to transition (Re=520) regime.
RSSCs allow observing the same region once at the same local time in a solar day and several times at the different local time in a solar day.
High-resolution AFM-topographs allow observing substructures of single membrane proteins at sub-nanometer resolution as well as their conformational changes, oligomeric state, molecular dynamics and assembly.
The loading level increases with each step, and the loading phases allow observing the modulus decrease, while the rest periods are introduced to observe modulus recovery after each loading level.
The combined treatment of electrochemical and XAS signals mutually supports the working hypothesis of full complementarity between the two techniques, that allow observing the pseudocapacitive reactions and its time evolution even in the presence of possible parasitic side-processes, and highlights the XAS features to be used as effective kinetic parameters.
Filtering at 880 nm allowed observing the emission of Nd3+ which substitutes Ca2+ in apatite.
In addition, it also allows observing fire, damage on building and similar disasters.
Some FPGAs include special debugging circuitry that allows observing internal nodes.
The geometry of the fiber allowed observing different interferences created by the microstructured fiber core section.
