Model reference adaptive hierarchical control framework for shake table tests

Earthquake Engineering &Structural Dynamics, Volume 54, Issue 1, Page 346-362, January 2025.
Abstract The structural response under earthquake excitation can be simulated by shake table tests. However, the performance of the shake table is affected by the Control‐Structure Interaction (CSI) effect. In recent years, nonlinear control algorithms were developed to compensate for the CSI effect.

Consistently Simulating a Wide Range of Atmospheric Scenarios for K2-18b with a Flexible Radiative Transfer Module

, 2020
The atmospheres of small, potentially rocky exoplanets are expected to cover a diverse range in composition and mass. Studying such objects therefore requires flexible and wide-ranging modeling capabilities.

On the Afrotropical genus Holmelgonia (Araneae, Linyphiidae), with the description of three new species from the Albertine Rift

European Journal of Taxonomy, 2014
Three new species of Holmelgonia were found in the mountain forest of Kibira National Park in Burundi: H. afromontana sp. nov. (♂♀), H. bosnasutus sp. nov. (♂♀) and H. disconveniens sp. nov. (♂). A key to the males in the genus, now containing 17 species,

Quantitative and clinical impact of MRI-based attenuation correction methods in [18F]FDG evaluation of dementia

EJNMMI Research, 2019
Background Positron emission tomography/magnetic resonance imaging (PET/MRI) is a promising diagnostic imaging tool for the diagnosis of dementia, as PET can add complementary information to the routine imaging examination with MRI.

Adaptive output-feedback following control for time-delay systems

Archives of Control Sciences, 2014
Adaptive control of the time-delay systems is presented in the paper. Despite the use of MRAC based design, only the model following (not perfect model following) is considered.
