Economic flexibility: a structural analysis [PDF]

open access: yes, 2007
Economic flexibility is much discussed in the academic literature but has no agreed definition. In neoclassical economics, a flexible economy can be secured only by removing structural rigidities that block relative price movements and hamper the ...

STRUCTURAL DAMAGE IDENTIFICATION WITH GENERALIZED FLEXIBILITY AND ADDED MASSES

open access: yesJixie qiangdu, 2016
In this study,a method is proposed to identify structural damages by the change of structural generalized flexibility. By adding known masses to the physical structure,measuring the lower modes of the mass-modified structure,and then using these new data

Research on the Control Strategy of Hydraulic Shaking Table Based on the Structural Flexibility

open access: yesIEEE Access, 2019
The frequency response characteristics of the hydraulic shaking table show the same as that of a two degree of freedom (DOF) resonance system due to the structural flexibility of the hydraulic shaking table.

Evaluating RNA Structural Flexibility: Viruses Lead the Way

open access: yesViruses, 2021
Our understanding of RNA structure has lagged behind that of proteins and most other biological polymers, largely because of its ability to adopt multiple, and often very different, functional conformations within a single molecule.

Human sirtuins: Structures and flexibility [PDF]

open access: yesJournal of Structural Biology, 2016
In recent years, sirtuins (SIRTs), members of histone deacetylases (HDACs) class III, have been found to modulate cellular processes related to the development of human aging-related pathologies (i.e. cancer, neurodegeneration, metabolic disorders).

Structural Damage Assessment Using Multiple-Stage Dynamic Flexibility Analysis

open access: yesAerospace, 2022
Vibration-based damage assessment technology is a hot topic in aerospace engineering, civil engineering, and mechanical engineering. In this paper, a damage assessment approach using multiple-stage dynamic flexibility analysis is proposed for structural ...

Flexible models with evolving structure [PDF]

open access: yesProceedings First International IEEE Symposium Intelligent Systems, 2003
Summary: A type of flexible model in the form of a neural network (NN) with evolving structure is discussed in this study. We refer to models with amorphous structure as flexible models. There is a close link between different types of flexible models: fuzzy models, fuzzy NN, and general regression models. All of them are proven universal approximators
