Generalized Boozer coordinates: A natural coordinate system for quasisymmetry [PDF]
Physics of Plasmas, 2021 We prove the existence of a straight-field-line coordinate system we call generalized Boozer coordinates. This coordinate system exists for magnetic fields with nested toroidal flux surfaces provided ∮dl/B (j·∇ψ)=0, where symbols have their usual meaning, and the integral is taken along closed magnetic field lines. All quasisymmetric fields, regardless

Synthesis of Control Algorithm for Position of Six–Axis Manipulator
Energy Engineering and Control Systems, 2022 The paper formulates the inverse kinematic problem for the robotic manipulator with six degrees of freedom. For the solution if this problem, the geometric method combined with the Denavit–Hartenberg transformation was applied.

Structural synthesis of two-dof differential screw mechanism by the multi-body kinematics
Nihon Kikai Gakkai ronbunshu, 2020 A novel structural synthesis of a mechanism based on the multibody kinematics is proposed in this paper. Instead of the degree-of-freedom analysis by the Grubler’s equation, numbers of the generalized coordinates and those of the constraint¨ equations ...

Solution of the mixed boundary problem for the Poisson equation on two-dimensional irregular domains
Informatika, 2023 Objectives. A finite-difference computational algorithm is proposed for solving a mixed boundary-value problem for the Poisson equation given in two-dimensional irregular domains.Methods. To solve the problem, generalized curvilinear coordinates are used.

PLANNING THE JOINT TRAJECTORY OF REDUNDANT KINEMATICS CHAIN [PDF]
Trakia Journal of Sciences, 2022 In a number of technological operations, the end-effector of an open kinematic chain must follow a spatial trajectory, and a necessary condition for the realization of the movement is the smooth change of the generalized coordinates.

Intersections of Multicurves on Small Genus Non–Orientable Surfaces
Journal of Mathematical Sciences and Modelling, 2021 Let $K_{n}$ ($n>1$) be an $n$--punctured non--orientable surface of genus $2$ with 1 boundary component. We give formulae for calculating the geometric intersection number of an arbitrary multicurve with a relaxed multicurve on $K_{n}$ given their ...
