On the determination of cusp points of 3-R\underline{P}R parallel manipulators [PDF]

open access: yes, 2010
This paper investigates the cuspidal configurations of 3-RPR parallel manipulators that may appear on their singular surfaces in the joint space. Cusp points play an important role in the kinematic behavior of parallel manipulators since they make ...

Computing Independent Variable Sets for Polynomial Ideals

open access: yesJournal of Mathematics, 2022
Computing independent variable sets for polynomial ideals plays an important role in solving high-dimensional polynomial equations. The computation of a Gröbner basis for an ideal, with respect to a block lexicographical order in classic methods, is huge,

An extension of Buchberger's criteria for Groebner basis decision

open access: yes, 2009
Two fundamental questions in the theory of Groebner bases are decision ("Is a basis G of a polynomial ideal a Groebner basis?") and transformation ("If it is not, how do we transform it into a Groebner basis?") This paper considers the first question. It

A note on Computing SAGBI-Grobner bases in a Polynomial Ring over a Field [PDF]

open access: yesComputer Science Journal of Moldova, 2006
In the paper [2] Miller has made concrete Sweedler's theory for ideal bases in commutative valuation rings (see [5]) to the case of subalgebras of a polynomial ring over a field, the ideal bases are called SAGBI-Grobner bases in this case.

Boolean Gröbner Basis Reductions on Finite Field Datapath Circuits Using the Unate Cube Set Algebra

open access: yesIEEE Transactions on Computer-Aided Design of Integrated Circuits and Systems, 2019
Recent developments in formal verification of arithmetic datapaths make efficient use of symbolic computer algebra algorithms. The circuit is modeled as an ideal in polynomial rings, and Gröbner basis (GB) reductions are performed over these polynomials ...
