Optimal periodic output feedback control: a continuous-time approach [PDF]
, 2007 : This paper addresses the problem of optimal static output feedback control of linear periodic systems. The proposed approach, which allows to deal with both stable and unstable open loop systems, relies on a continuous-time formulation of the control ...

The Periodic Table as a Cultural Meme [PDF]
, 2019 The Mendeleev periodic table is 150 years old this year. This article looks at how it has changed in its history and its wider recognition in human society.

Dynamical stability of two-dimensional metals in the periodic table [PDF]
Physical review B, 2020 We study the dynamical stability of two-dimensional (2D) metals from Li to Pb in the periodic table. Using a first-principles approach, we calculate the phonon band structure of 2D metals that have planar hexagonal (HX), buckled honeycomb (bHC), and ...

The St Andrews Periodic Table Wallchart and its Use in Teaching
Substantia, 2019 An early surviving copy of a periodic table of the elements wallchart is described and it is compared with other early versions of the periodic table. The status of chemistry teaching in St Andrews at the time and particularly the lectures of Professor ...

On solving periodic Riccati equations [PDF]
, 2008 Numerically reliable algorithms to compute the periodic non-negative definite stabilizing solutions of the periodic differential Riccati equation (PRDE) and discrete-time periodic Riccati equation (DPRE) are proposed. For the numerical solution of PRDEs,

Locally periodic unfolding method and two-scale convergence on surfaces of locally periodic microstructures [PDF]
, 2015 In this paper we generalize the periodic unfolding method and the notion of two-scale convergence on surfaces of periodic microstructures to locally-periodic situations.

The Periodic Table in Croatia [PDF]
Kemija u Industriji, 2011 The Croatian (Yugoslav) Academy of Sciences and Arts was the first academy to elect D. I. Mendeleev as its honorary member (1882), whereas the periodic table of the elements has been taught regularly at the Zagreb University since 1888.

Periodic table for topological bands with non-Hermitian symmetries [PDF]
Physical review B, 2018 Classifications of symmetry-protected topological (SPT) phases provide a framework to systematically understand the physical properties and potential applications of topological systems. While such classifications have been widely explored in the context

The Periodic Table and Kinetics?
CHIMIA, 2019 Mendeleev in his first publication ordered the chemical elements following an apparent periodicity of properties such as atomic volume and valence. The reactivity of the elements was only studied systematically many years later.
