Line Defects in One-Dimensional Hexagonal Quasicrystals

open access: yesMathematics
Using the eight-dimensional framework of the integral formalism of one-dimensional quasicrystals, the analytical expressions for the displacement fields and stress functions of line defects, which are dislocations and line forces, in one-dimensional ...

The genesis of tangential mass forces in lithospheric plates, and their role in geodynamics

open access: yesВестник Камчатской региональной ассоциации "Учебно-научный центр". Серия: Науки о Земле, 2020
The problem of determining small tangential mass forces in the Earth lithosphere is formulated. It is shown that the current state in understanding the shape of The Earth's physical surface and data on its geoid allow us to determine deviations of the ...

Multiple-Frequency Force Estimation of Controlled Vibrating Systems with Generalized Nonlinear Stiffness

open access: yesMathematics, 2023
An on-line estimation technique of multiple-frequency oscillatory forces combined with the Hilbert–Huang transform for an important class of actively controlled, forced vibrating mechanical systems with nonlinear stiffness forces is proposed.

Line Defects in Quasicrystals

open access: yesCrystals
The six-dimensional framework of the integral formalism for line defects (straight dislocations and line forces) in anisotropic elasticity has been extended to a 2n-dimensional integral formalism for line defects in quasicrystals (n=4,5,6 for one-, two-,

Peak Forces on Wave Energy Linear Generators in Tsunami and Extreme Waves

open access: yesEnergies, 2017
The focus of this paper is the survivability of wave energy converters (WECs) in extreme waves and tsunamis, using realistic WEC parameters. The impact of a generator damping factor has been studied, and the peak forces plotted as a function of wave ...

Lower Bounds for On-line Interval Coloring with Vector and Cardinality Constraints

open access: yes, 2016
We propose two strategies for Presenter in the on-line interval graph coloring games. Specifically, we consider a setting in which each interval is associated with a $d$-dimensional vector of weights and the coloring needs to satisfy the $d$-dimensional ...

Octilinear Force-Directed Layout with Mental Map Preservation for Schematic Diagrams [PDF]

open access: yes, 2014
We present an algorithm for automatically laying out metro map style schematics using a force-directed approach, where we use a localized version of the standard spring embedder forces combined with an octilinear magnetic force.

Automatic Speech Recognition Training Software for Joint Terminal Attack Controller Close Air Support Requests

open access: yesProceedings of the International Florida Artificial Intelligence Research Society Conference, 2022
Close air support (CAS) is a crucial element of joint fire support that requires intricate planning, coordination, and training of various ground and supporting air forces for safe and effective execution.

Spectroscopy of 26F to probe proton-neutron forces close to the drip line. [PDF]

open access: yesPhysical Review Letters, 2013
A long-lived J(π) = 4(1)(+) isomer, T(1/2) = 2.2(1) ms, has been discovered at 643.4(1) keV in the weakly bound (9)(26)F nucleus. It was populated at Grand Accélérateur National d'Ions Lourds in the fragmentation of a (36)S beam. It decays by an internal

CONTROLLING THE MOVEMENT OF HEXACOPTER ALONG THE INTENDED ROUTE WITH ENGINE FAILURE [PDF]

open access: yesScientific Journal of Silesian University of Technology. Series Transport
This article investigates the issue of controlling the movement of a hexacopter-type unmanned aerial vehicle around a route. The movement of the hexacopter is modeled as the motion of a rigid body, taking into account gravitational forces and aerodynamic
