Research on Iterative Learning Semi-active Control for Curve Passing of High-speed Train
机车电传动, 2020 When the high-speed train passes the curve, its dynamics performance deteriorates. In order to improve the dynamic performance of high-speed train when passing through different curves, the influence of semi-active control with yaw damper on its dynamic ...

Constructive algorithms for forming compound cubic Bezier curves in space and on plane [PDF]
Омский научный вестник, 2022 The article considers two graph-analytical algorithms. The first algorithm makes it possible to form a spatial curve passing through given nodal points with direction vectors specified at these points.

On the dimension of spaces of algebraic curves passing through $n$-independent nodes [PDF]
Proceedings of the YSU A: Physical and Mathematical Sciences, 2019 Let a set of nodes $\mathcal X$ in plain be $n$-independent, i.e., each node has a fundamental polynomial of degree $n.$ Suppose also that $|\mathcal X|= d(n,k-2)+2,$ where $d(n,k-2) = (n+1)+n+\cdots+(n-k+4)$ and $\ k\le n-1.$ In this paper we prove that there can be at most $4$ linearly independent curves of degree less than or equal to $k$ passing ...

Nonsingular curves passing through points of P2 in generic position, I
Journal of Algebra, 1985 For part I and the considered problem see the preceding review.] - In this part II the authors introduce new concepts of ''general position'' for n points and give evaluations for \(\delta\). A sample result is the following: let \(n=\left( \begin{matrix} d+2\\ 2\end{matrix} \right)+h,\) \(0\leq h\leq d+1\) and let \(W_ 1\supseteq ({\mathbb{P}}^ 2)^ n\)

Study on Gage Widening Methods for Small-Radius Curves
Applied Sciences, 2021 Existing gage widening standards and the influence of gage widening on the curve passing performance of trains and rail wear were examined. The existing gage widening theory can determine the minimum curve radius that needs to be widened, the widening ...

On the uniqueness of algebraic curves passing through $n$-independent nodes
, 2015 A set of nodes is called $n$-independent if each its node has a fundamental polynomial of degree $n.$ We proved in a previous paper [H. Hakopian and S. Toroyan, On the minimal number of nodes determining uniquelly algebraic curves, accepted in Proceedings of YSU] that the minimal number of $n$-independent nodes determining uniquely the curve of degree $
