Laser projection, such as that used in laser light shows, usually uses computer-drawn graphics. However, some restrictions are imposed by laser-scanned displays on these vector-based drawings. This paper presents a general vector-oriented drawing method to display computer vector graphics on different laser-scanned displays with optimization. The method considers how to solve the three fundamen...

After aulyzing the interaction betlreen the cutter and the inolute in machining processes of scroll wraps and its influence on the discharge angle and the compresiion ratio, a new method suggested by present authors for modification of the inTolute wrap of the scroll compressor is presented in this paper. The new method, different from any other method which has eTer been published, includes gr...

The graphic representation of family data for the computation of the coefficients of inbreeding [F] and relationship [r] can be replaced by an algebraic method. The organization of family data is facilitated by a data form which can be easily, thoroughly, and correctly completed, even by a layman. The computation of the coefficients is practically automatic and greatly reduces the possibility o...

We propose a new representation method, the multistage color-depth panoramic map (or panomap), for compressing 3D graphic objects. The idea of the proposed method is to transform a 3D graphic object, including both the shape and color information, into a single image. With a pseudo cylinder (or sphere), the color/depth information of a 3D graphic object can be recorded completely via a main pan...

In this short essay, I consider some relationships between the integrated cognitive-semiotic approach to cartographic representation that I develop in How Maps Work and Jacques Bertin’s contributions to cartographic and graphic theory. I relate my approach to his comprehensive semiologic framework for map and graphic design as well as his efforts toward a structured method of graphic informatio...

BACKGROUND The anaerobic threshold (AT) provides information on functional capacity in heart failure (HF). However, the visual determination of the AT by ventilatory methods is subjective, being susceptible to differences between examiners. OBJECTIVE To evaluate the inter- and intra-examiner reproducibility in the determination of the AT in patients with mild to moderate HF, using visual-grap...

The purpose of this paper is three fold. First, the major theoretical pattern relationships of TV and/or FM transmitting antennas are dealt with. Secend, the computer calculation method and designing of such patterns using the given relationships. And third, a method in which a computer graphic system can be used to design such antennas for a specific pattern is introduced and its results are p...

It is important to represent MPEG-4 BIFS with LASeR format to service the existing MPEG-4 scene in mobile environments. In this paper, a new method is suggested that watermark is inserted in the conversion process of 3D graphic nodes in MPEG-4 BIFS into LASeR 2D graphic nodes. This method uses the procedures to process z-axis coordinate value in order to process 3D nodes in BIFS and to process ...
