Shields-Harary numbers of graphs with respect to continuous concave cost functions

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 2003
The Shields-Harary numbers are a class of graph parameters that measure a certain kind of robustness of a graph, thought of as a network of fortified reservoirs, with reference to a given cost function.

Hierarchical interface-based supervisory control using the conflict preorder [PDF]

open access: yes, 2012
Hierarchical Interface-Based Supervisory Control decomposes a large discrete event system into subsystems linked to each other by interfaces, facilitating the design of complex systems and the re-use of components.

From Continuous to Discrete via V&V Bar

open access: yesScience & Philosophy, 2018
The ‘continuous’ and the ‘discrete’ in nature and in science live and fight forever. The questionnaires and the Lickert scales are indispensable and widely used tools in social sciences research.

(Me4N)(NO2)2C6H3CO2 NEW MCl2 (M = Zn, Co, Cd) AND SnR3Cl (R = Me, Ph) ADDUCTS: SYNTHESIS AND INFRARED STUDY

open access: yesScientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2014
Five new (Me4N)(NO2)2C6H3CO2 adducts with MCl2 (M = Zn, Co, Cd) and SnR3Cl (R = Me, Ph) have been synthesized and studied by infrared spectroscopy. The suggested structures are discrete, the anion behaving as mono- and bichelating ligand towards MX2, tri-

Construction of discrete-time model for port-controlled Hamiltonian systems with applications [PDF]

open access: yes, 2006
The issues of constructing a discrete-time model for Hamiltonian systems are in general different from those for dissipative systems. We propose an algorithm for constructing an approximate discrete-time model, which guarantees Hamiltonian conservation ...

Multiple solutions to a boundary value problem for an n-th order nonlinear difference equation

open access: yesElectronic Journal of Differential Equations, 1998
We seek multiple solutions to the n-th order nonlinear difference equation $$Delta^n x(t)= (-1)^{n-k} f(t,x(t)),quad t in [0,T]$$ satisfying the boundary conditions $$x(0) = x(1) = cdots = x(k - 1) = x(T + k + 1) = cdots = x(T+ n) = 0,.$$ Guo's fixed ...

Discrete Structures

open access: yes, 2012
This course describes discrete mathematics, which involves processes that consist of sequences of individual steps (as compared to calculus, which describes processes that change in a continuous manner). The principal topics presented in this course are
