Kinematics and Singularity Analysis of a 7-DOF Redundant Manipulator [PDF]
Sensors, 2021 A new method of kinematic analysis and singularity analysis is proposed for a 7-DOF redundant manipulator with three consecutive parallel axes. First, the redundancy angle is described according to the self-motion characteristics of the manipulator, the ...

Singularity analysis of 3-DOF planar parallel continuum robots with constant curvature links [PDF]
Frontiers in Robotics and AI, 2023 This paper presents the singularity analysis of 3-DOF planar parallel continuum robots (PCR) with three identical legs. Each of the legs contains two passive conventional rigid 1-DOF joints and one actuated planar continuum link, which bends with a ...

Unary profile of lambda terms with restricted De Bruijn indices [PDF]
Discrete Mathematics & Theoretical Computer Science, 2021 In this paper we present an average-case analysis of closed lambda terms with restricted values of De Bruijn indices in the model where each occurrence of a variable contributes one to the size.

Functional singular spectrum analysis [PDF]
Stat, 2021 In this paper, we develop a new extension of the singular spectrum analysis (SSA) called functional SSA to analyze functional time series. The new methodology is constructed by integrating ideas from functional data analysis and univariate SSA. Specifically, we introduce a trajectory operator in the functional world, which is equivalent to the ...

New insights into singularity analysis [PDF]
International Journal of Nonlinear Sciences and Numerical Simulation, 2020 Abstract In this work, we emphasize the use of singularity analysis in obtaining analytic solutions for equations for which standard Lie point symmetry analysis fails to make any lucid decision. We study the higher-dimensional Kadomtsev–Petviashvili, Boussinesq, and Kaup–Kupershmidt equations in a more general sense.

Enumeration of walks reaching a line [PDF]
Discrete Mathematics & Theoretical Computer Science, 2005 We enumerate walks in the plane $\mathbb{R}^2$, with steps East and North, that stop as soon as they reach a given line; these walks are counted according to the distance of the line to the origin, and we study the asymptotic behavior when the line has a

Some exact asymptotics in the counting of walks in the quarter plane [PDF]
Discrete Mathematics & Theoretical Computer Science, 2012 Enumeration of planar lattice walks is a classical topic in combinatorics, at the cross-roads of several domains (e.g., probability, statistical physics, computer science).

Analysis of a singular Boussinesq model [PDF]
Research in the Mathematical Sciences, 2018 Recently, a new singularity formation scenario for the 3D axi-symmetric Euler equation and the 2D inviscid Boussinesq system has been proposed by Hu and Luo based on extensive numerical simulations [15, 16]. As the firrst step to understand the scenario, models with simplified sign-definite Biot-Savart law and forcing have recently been studied in [7 ...
