This paper describes the design and implementation of a ROM-Less Direct Digital Frequency Synthesizer (DDS) using Bezier curve approximation. With Bezier curve approximation, phase values between 0 to π are mapped to sine amplitudes. Then, half wave symmetry of sine wave is exploited to construct full sine wave. The proposed approximation introduces maximum error of 7.9×10, which is equivalent ...

This paper has constructed a linear quadratic Bézier-like curve with two shape parameters. The proposed work is to design the Arabic fonts by using Bezier-like curves. focus of this study new functions and look at their application in designing fonts. Our procedures involve combination polynomial basis functions. rational non-rational are used modified as desired simply altering values paramete...

-Most of the CAD software, which are available currently, works only on the operating system (generally windows) for which they are designed. Alternatively, the commercial CAD software is dependent upon the operating system. If CAD software is designed such that it is Independent of the operating system, then such CAD software will be much beneficial for the present scenario of the CAD software...

Diffusion curves are a powerful vector graphic representation that stores an image as a set of 2D Bezier curves with colors defined on either side. These colors are diffused over the image plane, resulting in smooth color regions as well as sharp boundaries. In this paper, we introduce a new automatic diffusion curve coloring algorithm. We start by defining a geometric heuristic for the maximum...

In this paper, the smooth path planning problem is considered for a mobile robot based on the genetic algorithm and the Bezier curve. The workspace of a mobile robot is described by a new grid-based representation (2 × 2n grids) that facilitates the operations of the adopted genetic algorithm. The chromosome of the genetic algorithm is composed of a sequence of binary numbered grids (i.e., cont...

Motion sickness in self-driving cars is a key human factor that aggravates the passengers’ health autonomous vehicles and investigated following pages. As drivers turn into passengers dwell other activities, probability of car inevitable cars. Path planning could serve an important role reducing sickness. The present study establishes thresholds contribute to motion from vehicle’s dynamic point...

Farin proposed a method for designing Bezier curves with monotonic curvature and torsion. Such are relevant in design due to their aesthetic shape. The relies on applying matrix M the first edge of control polygon curve order obtain by iteration remaining edges. With this method, sufficient conditions $M$ provided, which lead definition Class A curves, generalising previous result Mineur et al ...
