This work introduces a new architecture for a parallel, six degree of freedom manipulator. The kinematic analysis of this redundant manipulator is provided. The proposed parallel mechanism allows easy implementation of redundant actuators, and has relatively large workspace in comparison to conventional six degree of freedom parallel devices. The kinematic analysis performed forms the basis for...

Factorial designs have broad applications in agricultural, engineering and scientific studies. In constructing and studying properties of factorial designs, traditional design theory treats all factors as nominal. However, this is not appropriate for experiments that involve quantitative factors. For designs with quantitative factors, level permutation of one or more factors in a design matrix ...

The goal of this paper is to prove the applicability of algorithm engineering and software design concepts to geometric computing through a vertical case study on the implementation of planar point location algorithms. The work is presented within the framework of the GeomLib project, aimed at developing an easy to use, reliable, and flexible library of robust and efficient geometric algorithms...

Given a parameterization of an algebraic rational curve in a projective space of arbitrary dimension, we introduce and study a new implicit representation of this curve which consists in the locus where the rank of a single matrix drops. Then, we illustrate the advantages of this representation by addressing several important problems of Computer Aided Geometric Design: The point-on-curve and i...

This paper studies geometric design of developable composite Bézier surfaces from two boundary curves. The number of degrees of freedom (DOF) is characterized for the surface design by deriving and counting the developability constraints imposed on the surface control points. With a first boundary curve freely chosen, ð2m þ 3Þ, ðm þ 4Þ, and five DOFs are available for a second boundary curve of...

We present a new algorithm in order to compute the multidimensional residue of a polynomial map based on a perturbation argument and the Generalized Transformation Law. Then we use it for studying some fundamental problems in Computer Aided Geometric Design.

Given an algebraic plane curve C defined by a rational parametrization P(t), we present formulae for the computation of the degree of C, and the multiplicity of a point. Using the results presented in [Sendra, J.R., Winkler, F., 2001. Tracing index of rational curve parametrizations. Computer Aided Geometric Design 18 (8), 771–795], the formulae simply involve the computation of the degree of a...

efficient system design and training human resources with the necessary skills is essential for every organization. managers' skills in using information technology results in greater efficiency at work and make decisions based on the information. this study investigates the design quality criteria and standards for rfid technology strategic management of university libraries is discussed....

DeVore, R.A., B. Jawerth and B.J. Lucier, Surface compression, Computer Aided Geometric Design 9 (1992) 219-239. We propose wavelet decompositions as a technique for compressing the number of a control parameters of surfaces that arise in Computer-Aided Geometric Design. In addition, we give a specific numerical algorithm for surface compression based on wavelet decompositions of surfaces into ...

In this survey, we will show some connections between several mathematical problems such as extrapolation, linear systems, totally positive matrices and computer-aided geometric design, with elimination techniques as the common tool to deal with all of them. c © 2000 Elsevier Science B.V.
