Three-Bar structure optimality criterion using the linear resizing rule

open access: yesRevista Facultad de Ingeniería Universidad de Antioquia, 2021
The static analysis of the indeterminate three-bar structure is developed using the Castigliano's first theorem, taking the lengths and inclination angles as variables. Some reductions are applied in the resulting set of equations to approximate them to

1,3,5-Triaryl-1,3,5-Triazinane-2,4,6-Trithiones: Synthesis, Electronic Structure and Linear Optical Properties

open access: yesMolecules, 2020
The synthesis of four new 1,3,5-triaryl-1,3,5-triazinane-2,4,6-trithione derivatives (thioisocyanurates) and two new partially thionated analogues from the corresponding 1,3,5-triaryl-1,3,5-triazinane-2,4,6-triones (isocyanurates) is reported, together ...

Interval state estimator for linear systems with known structure

open access: yesМіжнародний науково-технічний журнал "Проблеми керування та інформатики", 2023
It is often required to control a system whose state is not observable directly. Instead, there are indirect incomplete and noised measurements of its state.

Linear Structures in Blockciphers [PDF]

open access: yes, 2010
This paper is a somewhat modified and extended version of the article with the same title that appeared in Lect. Notes Comput. Sci. 304, 249- 266 (1988; Zbl 0659.94001). The contents are essentially the same. Only some of the arguments have been worked out in more detail, and a longer introduction has been inserted for those readers who are not so ...

Hypocoercivity and hypocontractivity concepts for linear dynamical systems

open access: yes, 2023
For linear dynamical systems (in continuous-time and discrete-time), we revisit and extend the concepts of hypocoercivity and hypocontractivity and give a detailed analysis of the relations of these concepts to (asymptotic) stability, as well as (semi ...

On the linear structure of cones

open access: yesCoRR, 2020
For encompassing the limitations of probabilistic coherence spaces which do not seem to provide natural interpretations of continuous data types such as the real line, Ehrhard and al. introduced a model of probabilistic higher order computation based on (positive) cones, and a class of totally monotone functions that they called "stable".

The cascade structure of linear instability in collapsible channel flows [PDF]

open access: yes, 2008
This paper studies the unsteady behaviour and linear stability of the flow in a collapsible channel using a fluid–beam model. The solid mechanics is analysed in a plane strain configuration, in which the principal stretch is defined with a zero initial ...

A field surveying on the geodetic control of engineering linear structures using a terrestrial laser scanner

open access: yesGeodesy and Cartography, 2019
The method of geodetic control of the road pavement using TLS is presented. The use of the terrestrial laser scanner can avoid some of the disadvantages of classical methods for determining the deformation of objects.

Linear Algebra and Smarandache Linear Algebra [PDF]

open access: yes, 2003
The present book, on Smarandache linear algebra, not only studies the Smarandache analogues of linear algebra and its applications, it also aims to bridge the need for new research topics pertaining to linear algebra, purely in the algebraic sense.
