NEW ZINC OXALATO AND HYDROGENOXALATO COMPLEXES: SYNTHESIS AND INFRARED STUDY
Journal of Engineering Studies and Research, 2017 Five new oxalato and hydrogenoxalato complexes with ZnBr2 have been synthesized and studied by infrared. Discrete structures have been suggested in the basis of spectroscopic data.

DEARYLATION IN THE INTERACTIONS BETWEEN (Et3NH)HC2O4 OR (Et3NH)2C2O4 AND SnPh3Cl: INFRARED STUDY
Journal of Engineering Studies and Research, 2017 Five new oxalato, hydrogenoxalato and hydrogenocarbonato adducts (three) and complexes (two) obtained on allowing (Et3NH)HC2O4 or (Et3NH)2C2O4 to react with SnPh3Cl have been studied by infrared spectroscopy, then discrete structures suggested on the ...

Local Causal States and Discrete Coherent Structures [PDF]
, 2018 Coherent structures form spontaneously in nonlinear spatiotemporal systems and are found at all spatial scales in natural phenomena from laboratory hydrodynamic flows and chemical reactions to ocean, atmosphere, and planetary climate dynamics ...

Manifolds and discrete structures [PDF]
Kodai Mathematical Journal, 1983 The starting point of this paper is the connection between smooth structures on a manifold M, the algebra of smooth functions on M and the behaviour of smooth functions on a dense subset of M. It is shown that if \((a_ n)\) and \((b_ n)\) are dense sequences in M with \(a_ m\neq a_ n\) and \(b_ m\neq b_ n\) for \(m\neq n\) then there is a ...

Intersecting families of discrete structures are typically trivial [PDF]
, 2015 The study of intersecting structures is central to extremal combinatorics. A family of permutations $\mathcal{F} \subset S_n$ is \emph{$t$-intersecting} if any two permutations in $\mathcal{F}$ agree on some $t$ indices, and is \emph{trivial} if all ...

Dynamic response of structures constructed from smart materials [PDF]
, 1995 The dynamic analysis of structures constructed of homogeneous smart materials is greatly simplified by the observation that the eigenfunctions of such structures are identical to those of the same structures constructed entirely of purely elastic ...

Nonstationary discrete theory of excitation of periodic structures and its application for simulation of traveling-wave tubes [PDF]
Известия высших учебных заведений: Прикладная нелинейная динамика, 2021 Aim. This article presents a review of the nonstationary (time-domain) discrete theory of excitation of periodic electromagnetic structures and discusses applications of the theory for simulation of traveling-wave tube (TWT) microwave power amplifiers ...
