Rigorous Result for the CHKNS Random Graph Model [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2003
We study the phase transition in a random graph in which vertices and edges are added at constant rates. Two recent papers in Physical Review E by Callaway, Hopcroft, Kleinberg, Newman, and Strogatz, and Dorogovstev, Mendes, and Samukhin have computed ...

Fractal Derivatives and Singularity Analysis of Frequency—Depth Clusters of Earthquakes along Converging Plate Boundaries

open access: yesFractal and Fractional, 2023
Fractional calculus (FC) has recently received increasing attention due to its applications in many fields involving complex and nonlinear systems. However, one of the key challenges in using FC to deal with fractal or multifractal phenomena is how to ...

Singularity Analysis of Generating Functions [PDF]

open access: yesSIAM Journal on Discrete Mathematics, 1990
This work presents a class of methods by which one can translate, on a term-by-term basis, an asymptotic expansion of a function around a dominant singularity into a corresponding asymptotic expans...

A repertoire for additive functionals of uniformly distributed m-ary search trees [PDF]

open access: yesDiscrete Mathematics & Theoretical Computer Science, 2005
Using recent results on singularity analysis for Hadamard products of generating functions, we obtain the limiting distributions for additive functionals on $m$-ary search trees on $n$ keys with toll sequence $(i) n^α$ with $α ≥ 0 (α =0$ and $α =1 ...

Singular perturbations and nonstandard analysis [PDF]

open access: yesTransactions of the American Mathematical Society, 1979
We study by methods of nonstandard analysis second order differential operators with zero order coefficients which are too singular to be defined by standard functions. In particular we study perturbations of the Laplacian in

Velocity and Singularity Analysis of a 5-DOF (3T2R) Parallel-Serial (Hybrid) Manipulator

open access: yesMachines, 2022
This article presents the velocity and singularity analysis for a five-degree-of-freedom (5-DOF) parallel-serial manipulator. The hybrid structure of the manipulator combines a tripod-like parallel part and a serial part, represented as two carriages ...

Instantaneous Kinematics and Free-from-Singularity Workspace of 3-XXRRU Parallel Manipulators

open access: yesRobotics, 2023
3-XXRRU parallel manipulators (PMs) constitute a family of six-degrees-of-freedom (DOF) PMs with three limbs of type XXRRU, where R and U stand for revolute pair and universal joint, respectively, and XX indicates any actuated two-DOF mechanism that ...

Synergy between Ocean Variables: Remotely Sensed Surface Temperature and Chlorophyll Concentration Coherence

open access: yesRemote Sensing, 2020
The similarity of mesoscale and submesoscale features observed in different ocean scalars indicates that they undergo some common non-linear processes.

Singularity Analysis and Complete Methods to Compute the Inverse Kinematics for a 6-DOF UR/TM-Type Robot

open access: yesRobotics, 2022
Improving the strategies employed to control robotic arms is of great importance because of the increase in their use in advanced supervisory control strategies, such as digital twins.

A Novel 3-URU Architecture with Actuators on the Base: Kinematics and Singularity Analysis

open access: yesRobotics, 2020
Translational parallel manipulators (TPMs) with DELTA-like architectures are the most known and affirmed ones, even though many other TPM architectures have been proposed and studied in the literature.
