An Approach to Character Generation using Cubic Splines

IEEE Transactions on Consumer Electronics, 1983
The importance of Computer Graphics as a medium of man-machine communication cannot be over- emphasized. Until recently, computer graphics technology was relatively expensive to permit its widespread use. However, with the rapid decline in the cost of LSI hardware and display devices, computer graphics has found acceptance in diverse applications such ...

Analytic definition of a product of cubic character

Ukrainian Mathematical Journal, 1975
The author introduces three functions of two complex variables defined by \[ c_j(z_1,z_2)=\sum_{k=0}^3 \rho^{jk} \exp\{2\pi i(\rho^kz_1+\rho^{2k}z_2)\}\qquad (i=1,2,3), \] where \(\rho=\exp(2\pi i/3)\) and determines their groups of periods. This allows him to give a new form for a product \(\Phi\), related to cubic characters, defined in a previous ...

On grain boundary character distribution in materials with cubic structure

Interface Science, 1997
From analysis of numerous experimental data on grain boundary (GB) statistics in polycrystals it has been established that certain groups of materials with cubic structure reveal similar GB character distributions (GBCD) (distribution of GBs by reciprocal density of coincidence sites ∑).

Contrast Factors and Character of Dislocations in Cubic and Hexagonal Crystals

Materials Science Forum, 2004
Anisotropic strain broadening of diffraction peaks can be parameterised by dislocation contrast factors. A comprehensive software has been developed and made available through the internet to determine the individual and averaged contrast factors which are also compiled for cubic and hexagonal crystals.

Basic processes of Chinese character based on cubic B-spline wavelet transform

IEEE Transactions on Pattern Analysis and Machine Intelligence, 2001
A novel approach based on cubic B-spline wavelet transform is proposed to process Chinese character including character compression, type zooming-in, and typeface composition. The basic idea is that a Chinese character is described by its contours which are represented by cubic B-spline functions, and each contour is decomposed into the details or the ...

The characters of the cubic surface group

Proceedings of the Royal Society of London. Series A. Mathematical and Physical Sciences, 1956
The characters of the cubic surface group G are got by using its representation as a group of orthogonal projectivities in a four-dimensional space a over GF (3). In α , G permutes 27 pentagons transitively and 6 other characters, in addition to

Effect of grain boundary character distribution on soft magnetic property of face-centered cubic FeCoNiAl0.2 medium-entropy alloy

Materials Characterization, 2020
Abstract The impact of grain boundary character distribution on soft magnetic properties of as-cast, deformed and recrystallized FeCoNiAl0.2 medium-entropy alloys (MEAs) with single face-centered cubic (FCC) phase was investigated. Electron backscatter diffraction (EBSD) results show that the existence of a large number of random grain boundaries (71.

Dislocation character transition and related mechanical response in a body-centered cubic single crystal

Scripta Materialia, 2012
In situ compression of a body-centered cubic single crystal Fe–3% Si pillar in transmission electron microscopy (TEM) by scanning TEM mode was performed to observe a single dislocation moving through the pillar in real time. The deformation is characterized by a series of pronounced pop-ins, which are accompanied by increases in stress.

Combined features of cubic B-spline wavelet moments and Zernike moments for invariant character recognition

Proceedings International Conference on Information Technology: Coding and Computing, 2002
In this paper a new method of combining cubic B-spline wavelet moments (WMs) and Zernike moments (ZMs) into a common feature vector is proposed for invariant pattern classification. By doing so, the ability of ZMs to capture global features and WMs to differentiate between subtle variations in description can be utilized at the same time.

Implications of cubic physical/aerodynamic non-linearities on the character of the flutter instability boundary

International Journal of Non-Linear Mechanics, 2003
The present paper deals with a study of the benign and catastrophic characters of the flutter instability boundary of 2-D lifting surfaces in a supersonic flow field. The objectives of this work are: (i) to contribute to a better understanding of the implications of aerodynamic and physical non-linearities on the character of the flutter boundary and ...
