Modeling and Animation of Generalized Cylinders with Variable Radius Offset Space Curves
- THE JOURNAL OF VISUALIZATION AND COMPUTER ANIMATION
, 1994
"... A method is presented for the modeling and animation of generalized cylinders with variable radius offset space curves. The boundary surface of a generalized cylinder is constructed: either as a translational sweep of cross-sectional curves along the skeleton curve, or as a rotational sweep of profi ..."

Reduction of lateral forces between the railway vehicle and the track in small-radius curves by means of active elements
, 2011
"... This paper deals with a possibility of reduction of guiding forces magnitude in small-radius curves by means of active elements. These guiding forces characterize the lateral force interaction between the rail vehicle and the track and influence the wear of wheels and rails in curves. Their magnitud ..."

The Deformation Analysis of the Curved Box Girder Bridges under Different Radius
"... This paper investigates the influence of radius on the deformation of curved box girder bridges under the action of pre-stressed tendons. A spiral pre-stressed concrete box girder bridge in Chongqing is analyzed by using nonlinear finite element program ANSYS. The five different curved bridge models ..."

Curvature-Induced Bound States In Quantum Waveguides In Two And Three Dimensions
- Math. Phys
, 1995
"... Dirichlet Laplacian on curved tubes of a constant cross section in two and three dimensions is investigated. It is shown that if the tube is non--straight and its curvature vanishes asymptotically, there is always a bound state below the bottom of the essential spectrum. An upper bound to the number ..."

The Cost Of Not Knowing The Radius Helmut Rieder
, 2006
"... Robust Statistics considers the quality of statistical decisions in the presence of deviations from the ideal model, where deviations are modelled by neighborhoods of a certain size about the ideal model. We introduce a new concept of optimality (radius-minimaxity) if this size or radius is not prec ..."

AVEC ‘04 Models of Driver Speed Choice in Curves
"... Present understanding of driver speed choice in curves is reviewed, and published mathematical models are compared and evaluated. Preliminary data gathered from a fixed-base driving simulator at CUED are used to evaluate the models. It is found that road width and curve radius are significant influe ..."

Curve shape Modification and Fairness Evaluation
- Proceedings of the ASME 2007 International Design Engineering Technical Conferences & Computers and Information in Engineering Conference, 2007, CD-ROM
"... ABSTRACT A method to generate a quintic NURBS curve which passes through the given points is described. In this case, there are four more equations than there are positions of the control points. Therefore, four gradients which are the first derivative of a NURBS equation are assigned to the given ..."

of given points with gradients. A method to modify NURBS curve shape according to the specified radius of curvature distribution to realize an aesthetically pleasing freeform curve is described. The differences between the NURBS curve radius of curvature and the specified radius of curvature is minimized
