Description of Concrete Creep under Time-Varying Stress Using Parallel Creep Curve
Autor: Yeong-Seong Park, Yong-Hak Lee, Youngwhan Lee
Publikováno v: Advances in Materials Science and Engineering, Vol 2016 (2016)
An incremental format of creep model was presented to take account of the development of concrete creep due to loading at different ages. The formulation was attained by introducing a horizontal parallel assumption of creep curves and combining it wi

Publikováno v: Pharmaceutics, Vol 12, Iss 4, p 311 (2020)
As the main symptom of Alzheimer’s disease-related dementia is memory loss, patient compliance for donepezil hydrochloride (donepezil), administered as once-daily oral formulations, is poor. Thus, we aimed to design poly(lactic-co-glycolic acid) (P

Publikováno v: Journal of Sensors, Vol 2020 (2020)
Particulate matters (PM) have become one of the important pollutants that deteriorate public health. Since PM is ubiquitous in the atmosphere, it is closely related to life quality in many different ways. Thus, a system to accurately monitor PM in di

Reinforcement Learning Guided by Double Replay Memory
Autor: Yong-Hak Lee, JiSeong Han, Kichun Jo, JunSang Cho, Eunseon Sim, Wontaek Lim, Kyoungmin Ko, SungHwan Kim
Publikováno v: Journal of Sensors, Vol 2021 (2021)
Experience replay memory in reinforcement learning enables agents to remember and reuse past experiences. Most of the reinforcement models are subject to single experience replay memory to operate agents. In this article, we propose a framework that

Effects of shrinkage variation within beam depth and bending creep on flexural behavior of RC members
Autor: Seung-Gyu Kim, Yong-Hak Lee
Publikováno v: Engineering Structures. 249:113315
The effects of shrinkage variation within the beam depth and bending creep on the time-dependent flexural behavior of reinforced concrete (RC) beams were examined via two sets of experiments and numerical analyses. Each test set included four types o

Incremental Formulation of Concrete Creep under Stress History
Autor: Si Hyung Park, Ta Lee, Yeong Seong Park, Yong Hak Lee
Publikováno v: Applied Mechanics and Materials. 865:313-319
An incremental format of the age-dependent constitutive equation was derived by expanding the total form of the constitutive equation by using the first-order Taylor series to describe the persistent change in the creep-causing stress state as well a
