Three-dimensional deformation using directional polar coordinates
Jin X., Li Y. Journal of Graphics Tools 5(2): 15-24, 2000. Type: Article
The authors discuss existing methods of ray-tracing for non-tesselated nonuniform rational B-spline (NURBS) surfaces carefully and combine them into a detailed method for efficient execution. They have to be commended for making the so...

Superconvergent interpolants for collocation methods applied to mixed-order BVODEs
Enright W., Sivasothinathan R. ACM Transactions on Mathematical Software 26(3): 323-351, 2000. Type: Article
In the output of the software package COLNEW/COLSYS for separated boundary value problems of mixed-order systems of ordinary differential equations (ODEs), the approximation is of much higher precision at the Gauss points used for the ...

Reduced Gro¨bner bases under composition
Gutierrez J., San Miguel R. Journal of Symbolic Computation 26(4): 433-444, 1998. Type: Article
Composition of polynomials (replacing the variables of onepolynomial by other polynomials) is an important numerical technique inmany applications. H. Hong has shown [1] that compositions with a set&THgr; of polynomials commutes wi...

Elements of applied bifurcation theory (2nd ed.)
Kuznetsov Y., Springer-Verlag New York, Inc., New York, NY, 1998. Type: Book (9780387983820)
Bifurcation theory studies the behavior of parameter-dependent differential dynamical systems and parameter-dependent discrete-time dynamical systems when the parameters vary in the neighborhood of a parameter value at which the differ...

Decomposing polynomial systems into simple systems
Wang D. (ed) Journal of Symbolic Computation 25(3): 295-314, 1998. Type: Article
The preparation of systems of algebraic equations for effective solutions, using either Gröbner bases or Ritt characteristic sets, is notoriously difficult and time-consuming. In this paper, some ideas of J. M. Thomas [1] are ...

Error guided design of a 3D vision system
Georgis N., Petrou M., Kittler J. IEEE Transactions on Pattern Analysis and Machine Intelligence 20(4): 366-379, 1998. Type: Article
The authors note that 3D vision systems are not practically usable if no estimates of errors and sensitivity are available. They consider the problem of describing the surface of a rectangular solid from two plane images and use projec...

The switching-method in multiple shooting
Bellavia S., Macconi M., Morini B. Computing 60(3): 275-283, 1998. Type: Article
In the shooting method for nonlinear boundary value problems of nonlinear differential equations with unique solutions, local integration is used to provide the data for a global (usually, damped) Newton approximation for a high-dimens...

On testing a bivariate polynomial for analytic reducibility
McCallum S. Journal of Symbolic Computation 24(5): 509-535, 1997. Type: Article
The author works out all the complicated details of a method of testing for the reducibility of a polynomial, first suggested by Kuo [1]. The notion of reducibility used here is in an algebraically closed field of formal power series. ...

Chaos in electronics
van Wyk M., Steeb W., Kluwer Academic Publishers, Norwell, MA, 1997. Type: Book (9780792345763)
Being more an encyclopedia than a textbook, this work will be most useful to people who want to learn what is known about this new field and where to find details. There are no exercises, but the bibliography contains 881 items. The in...

The equational logic of fixed points
Bloom S., Ésik Z. Theoretical Computer Science 179(1-2): 1-60, 1997. Type: Article
The authors survey the category of partially ordered sets in which each partially ordered subset has a least upper bound. No proofs are given. They state that every endomorphism f (or every order-preserving map of a ...
