[reaction: see text] A new curable arylamine containing a perfluorocyclobutane (PFCB) structure without an acidic group was synthesized. The material was thermally cured on ITO after spin-coating. The polymer showed excellent solvent resistance, high thermal stability, high transparency, and good surface smoothness.

We discuss G smoothness conditions for rectangular and triangular Gregory patches. We then incorporate these G conditions into a surface fitting algorithm. Knowledge of the patch type is inconsequential to the formulation of the G conditions, hence the term agnostic G Gregory surfaces.

In this study, a process has been developed for durable coating of sericin on polyester. Pre modification of polyester with alkali (sodium hydroxide) has been carried out to incorporate polar entities on its inert surface. 10g/L of sericin with 30mL/L of glutaraldehyde, cured at 130°C for 2min has been optimized for its application on modified surface. Treated samples are tested for surface smo...

INTRODUCTION The finishing and polishing phases are essential to improve smoothness and shining on the surface of acrylic resins used to make removable orthodontic appliances. A good surface finishing reduces roughness, which facilitates hygiene, prevents staining and provides greater comfort to the patients. OBJECTIVE The aim of this paper was to analyze the changes on surface morphology of ...

There are a number of applications in which increasing the smoothness of a mesh is desirable. A compelling example is noise removal. When meshes are constructed from acquired data, measurement error can result in a smooth surface being approximated with a rough mesh. Smoothing the mesh can attenuate this noise. Another application is surface subdivision. Taubin [1] cites a class of algorithms t...

A new method is presented to the B-spline surface presentation of an object defined by a set of parallel slices. For the application of Bspline inversion procedure, the methods about the data points generated are mainly introduced. The mesh of the data points is generated from interpolation curves of the vertex of the contour, which enable the interpolating surface to approximate the original o...

A C1 piecewise rational trigonometric cubic function with four shape parameters has been constructed to address the problem of visualizing positive data. Simple data-dependent constraints on shape parameters are derived to preserve positivity and assure smoothness. The method is then extended to positive surface data by rational trigonometric bicubic function. The order of approximation of deve...

In this talk it is shown a way for constructing magnetic surface sources for stationary axisymmetric electrovac spacetimes possessing a non-smooth electromagnetic Ernst potential. The magnetic moment density is related to this lack of smoothness and its calculation involves solving a linear elliptic differential equation. As an application the results are used for constructing a magnetic source...

A novel system for depth estimation is proposed with the use of Symbiotic Genetic Algorithms for the continuous problem of disparity surface approximation. The approach is based on the decomposition of the entire surface to very small non-overlapping patches described by low-order bivariate polynomials and the use of symbiotic optimisation to enforce smoothness at the boundaries of these patche...

Most shape estimation algorithms assume images of smooth surfaces with constant surface reflectance and often require knowledge of illuminant positions. These two requirements limit the applicability of such approaches to a small subset of imaged objects. In this paper a variational approach to the shape-from-color problem is presented that requires no knowledge of scene illuminants, and makes ...
