Reinforcement detail: Stress trajectory‐oriented corbel reinforcement

Structural Concrete, 2023
AbstractThe article presents a novel design of concrete corbels, where horizontal and vertical stirrups are replaced by main reinforcement bars that are bent down into the corbel web, following the principal stress lines. A test series of three specimen pairs of fanned‐out and conventional reinforcement design, supported by finite element analysis ...

Energy-Efficient Gait Optimization of Snake-Like Modular Robots by Using Multiobjective Reinforcement Learning and a Fuzzy Inference System

IEEE Access, 2022
Snake-like modular robots (MRs) are highly flexible, but, to traverse a challenging terrain or explore a region of interest, MR needs to attain efficient locomotion depending on a tradeoff between objectives like forward velocity and power consumption of

GRADED DIFFERENTIAL REINFORCEMENT: RESPONSE‐DEPENDENT REINFORCER AMOUNT [PDF]

Journal of the Experimental Analysis of Behavior, 1984
After key pecking had been autoshaped, six pigeons were exposed to a condition in which the duration of grain availability at the end of an 8‐second trial depended on the number of responses emitted during the trial (0.25‐second access to grain per response).
