Effect of Randomness of Parameters on Amplification of Ground Motion in Saturated Sedimentary Valley

open access: yesApplied Sciences, 2023
Based on Biot’s theory and the indirect boundary element method (IBEM), the Monte Carlo method is utilized to generate random samples to calculate the displacement response of a saturated sedimentary valley under SV wave incidence.

Amplification Effect of Ground Motion in Offshore Meandering Sedimentary Valley

open access: yesShock and Vibration, 2021
A sedimentary valley has a visible amplification effect on a seismic response, and the current 2D topographies cannot truthfully reflect the twists and turns of a large-scale river valley.

User Preference-Based Demand Response for Smart Home Energy Management Using Multiobjective Reinforcement Learning

open access: yesIEEE Access, 2021
A well-designed demand response (DR) program is essential in smart home to optimize energy usage according to user preferences. In this study, we proposed a multiobjective reinforcement learning (MORL) algorithm to design a DR program.

Effort reinforces learning

open access: yesThe Journal of Neuroscience, 2021
Humans routinely learn the value of actions by updating their expectations based on past outcomes – a process driven by reward prediction errors (RPEs). Importantly, however, implementing a course of action also requires the investment of effort. Recent work has revealed a close link between the neural signals involved in effort exertion and those ...

Reinforced Logics [PDF]

open access: yesNagoya Mathematical Journal, 1966
The device of representing a predicate by a universal sentence gives rise to logics of higher order. To represent an object constructed by a series of certain steps, we usually use terms. To represent a predicate constructed by a series of certain steps, we now use sentences in general.
