Decentralized state estimation for different substructure layouts of an adaptive high-rise structure

open access: yesMathematical and Computer Modelling of Dynamical Systems
Active control in adaptive structures allows for reducing the structural weight of a building and thus to drastically decrease the construction sector’s global impact. For an active control, it is necessary to estimate the state.

ON PERIODIC DYNAMICAL SYSTEMS [PDF]

open access: yesChinese Annals of Mathematics, 2004
In this paper, we investigate the existence and the global stability of periodic solution for dynamical systems with periodic interconnections, inputs and self-inhibitions. The model is very general, the conditions are quite weak and the results obtained are universal.

Effective Hamiltonian approach to adiabatic approximation in open systems [PDF]

open access: yes, 2006
The adiabatic approximation in open systems is formulated through the effective Hamiltonian approach. By introducing an ancilla, we embed the open system dynamics into a non-Hermitian quantum dynamics of a composite system, the adiabatic evolution of the

A system dynamics glossary

open access: yesSystem Dynamics Review, 2019
As a narrowly focused dictionary, this glossary defines commonly used terms that are central to traditional system dynamics and some more general terms that have special meanings or particular importance within system dynamics. General terms that have no

River linking in India: Downstream impacts on water discharge and suspended sediment transport to deltas

open access: yesElementa: Science of the Anthropocene, 2018
To expand agricultural production and address water scarcity, India is moving forward with the National River Linking Project (NRLP), which will connect 44 rivers via 9,600 km of canals. Here, we compile the first complete database of proposed NRLP dams,
