Increasing Precision without Altering Treatment Effects: Repeated Measures Designs in Survey Experiments

American Political Science Review, 2021
The use of survey experiments has surged in political science. The most common design is the between-subjects design in which the outcome is only measured posttreatment.

Maximizing precision over extended unambiguous range for TOF range imaging systems [PDF]

, 2010
The maximum unambiguous range for time-of-flight range imaging systems is inversely proportional to the chosen modulation frequency. However, increasing the unambiguous range by decreasing the modulation frequency will generally also degrade the range ...
