Condition Rating of Bridge Decks with Fuzzy Sets Modeling for SF-GPR Surveys

Remote Sensing, 2023
Highway agencies monitor the condition of thousands of bridge decks every year. Even though Ground Penetrating Radar (GPR) has been used in bridge-deck evaluation, Step-Frequency GPR (SF-GPR) provides advanced condition assessment yet requires extensive ...

Response rate and reinforcement rate in Pavlovian conditioning. [PDF]

Journal of Experimental Psychology: Animal Behavior Processes, 2011
Four experiments used delay conditioning of magazine approach in rats to investigate the relationship between the rate of responding, R, to a conditioned stimulus (CS) and the rate, r, at which the CS is reinforced with the unconditioned stimulus (US). Rats were concurrently trained with four variable-duration CSs with different rs, either as a result ...

Listening to limericks: a pupillometry investigation of perceivers’ expectancy [PDF]

, 2013
What features of a poem make it captivating, and which cognitive mechanisms are sensitive to these features? We addressed these questions experimentally by measuring pupillary responses of 40 participants who listened to a series of Limericks.
