Hamiltonian dynamics with external forces and observations [PDF]

open access: yesMathematical Systems Theory, 1981
The author gives a definition of a Hamiltonian system with input and output. Let \((M,\omega)\) (state space) and \((W,\omega^e)\) (external input-output space) be symplectic manifolds, \({\dot \omega}\) be a symplectic form generated on \(TM\), \(\Omega =\pi^*_1{\dot \omega}- \pi^*_2\omega^e\) is a symplectic form on \(TM\times W\), where \(\pi_1\), \(

Army Ground Forces mobilization plan.

open access: yes, 2020
Headquarters AGF has evolved a detailed mobilization plan for the expansion of the Army Ground Forces and Army Ground Force-type units from the projected numbers of units in existence in the Zone of Interior on 1 July 1946.

Load estimation from photoelastic fringe patterns under combined normal and shear forces [PDF]

open access: yes, 2009
Recently there has been some spurt of interests to use photoelastic materials for sensing applications. This has been successfully applied for designing a number of signal-based sensors, however, there have been limited efforts to design image-based ...

Dynamic analysis of runout correction in milling [PDF]

open access: yes, 2010
Tool runout and its effects is an important area of research within modelling, simulation, and control of milling forces. Tool runout causes tool cutting edges to experience uneven forces during milling.

Mathematical methodology for optimization of the clamping forces accounting for workpiece vibratory behaviour

open access: yesInternational Journal for Simulation and Multidisciplinary Design Optimization, 2014
This paper addresses the problem of determining the minimum clamping forces that ensure the dynamic fixturing stability. The clamping force optimization problem is formulated as a bi-level nonlinear programming problem and solved using a computational ...

Identification of a Shiga toxin A‐derived peptide internalized into Gb3 receptor‐bearing cells via interaction with the Shiga toxin B subunit

open access: yesFEBS Letters, EarlyView.
The process of internalization of the Shiga toxin A subunit via formation of a complex with the Shiga toxin B subunit, which specifically binds to the Gb3 receptor. The peptide is designed to act as a carrier of drugs into cancer cells. Here, we explored the potential of peptides derived from the catalytic A subunit of Shiga toxin (STxA) to be drug ...

Fundamental forces and their dynamics

open access: yesGeneral Relativity and Gravitation, 2022
In this essay, we wish to propose a general principle: \it{the equation of motion or dynamics of a fundamental force should not be prescribed but instead be entirely driven by geometry of the appropriate spacetime manifold, and the equation is then obtained by employing only the geometric property without appeal to an action.} The motivation for this ...

A probabilistic estimate of the vertical dynamic forces acting on the track, in the model of a three-layer beam under the influence of a four-axle freight car

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2018
The article contains a method for determining the ma-the permanent way as deflections, angles of section rotation, bending trix of mutual spectral densities of vertical dynamic forces acting on a moments, transverse forces, stresses of its three-layer ...
