The idea of quantity at the origin of the legitimacy of mathematization in physics [PDF]

open access: yes, 2003
Newton's use of mathematics in mechanics was justified by him from his neo-platonician conception of the physical world that was going along with his «absolute, true and mathematical concepts» such as space, time, motion, force, etc.

D'Alembert's formula and periodic mild solutions to iterated higher-order differential equations in Hilbert spaces

open access: yesElectronic Journal of Differential Equations, 2016
Summary: We give necessary and sufficient conditions for the periodicity of solutions of mild solutions to the iterated higher-order differential equation \[ \prod_{j=1}^{n}(\frac{d}{dt}-A_j)u(t)=f(t), \quad 0 \leq t\leq T, \] in a Hilbert space. Our results are illustrated with examples and applications.

Boundary-value problems for wave equations with data on the whole boundary

open access: yesElectronic Journal of Differential Equations, 2016
In this article we propose a new formulation of boundary-value problem for a one-dimensional wave equation in a rectangular domain in which boundary conditions are given on the whole boundary.

An example of calculating time, speed and brake way of the car on the site of the second braking position at the hump yard under the influence of small crosswinds

open access: yesВестник Научно-исследовательского института железнодорожного транспорта, 2016
To present day the speed of sliding car in the theory of calculation of marshaling hump determined by the formula of free falling body, where the acceleration of free falling bodies are given with the inertia of the wheelsets, which is unacceptable ...

Studies in the History of Probability and Statistics. XXXV: Multiple decrements or competing risks [PDF]

open access: yes, 2017
Given two states A and B such that individuals in state A have mutually exclusive probabilities, possibly dependent on the time spent in state A, of leaving that state because of (i) death, or (ii) passage to state B, what is the probability of an ...
