For purposes of designing targeted cataclysmic variable (CV) detection surveys and interpreting results of other projects with many CV detections such as the ChaMPlane Survey, we have created a model of the CV distribution in the Galaxy. It is modeled as a warped, flared exponential disk with a gaussian vertical distribution. Extinction is based on a detailed Galactic dust and gas model. A lumi...

This chapter presents our solution to the CoCoME assignment that is based on the Fractal component model. The solution involves (i) modeling architecture in Fractal ADL, (ii) specification of component behavior via behavior protocols, (iii) checking compatibility of components, (iv) verification of correspondence between component code and behavior specification, and (v) run-time monitoring of ...

Breast cancer is a leading cause of mortality among women. This paper presents a fast fractal method to model breast background regions based on entropy, for the detection breast cancer. When the modeled mammogram is taken out from the original image the presence of microcalcifications can be enhanced. The tremendous encoding time involved is the major drawback of fractal modeling method. In th...

We report the use of MGS, a declarative and rule-based language, for the modeling of various self-assembly processes. The approach is illustrated on the fabrication of a fractal pattern, a Sierpinsky triangle, using two approaches: by accretive growth and by carving. The notion of topological collections available in MGS enables the easy and concise modeling of Wang tiles on various lattice geo...

Since Euclid (300 BC) we have been used to perceiving nature with the concept of a threedimensional (3-D) geometry. We measure linear structures in one dimension, area-like structures in two dimensions, and volume-like structures in three dimensions. However, when we measure an object in terms of these three dimensions, we are aware that the geometric model describes a solid body, while a natur...

Antenna Miniaturization Using Fractals Richa Garg, AP ECE Deptt., [email protected], J.C.D.C.O.E., Sirsa ABSTRACTThe use of fractal geometry in designing antenna has been a resent topic of interest. Fractal shape has their own unique characteristics that the improved antenna performance can be achieved without degrading the antenna properties. Modern telecommunication system requires antenn...

This paper provides a time domain model for the propagation of transient ultrasonic waves in self-similar porous material having rigid frame. is based on formalism Stillinger–Palmer–Stavrinou, which consists modeling fractal as medium with non-integer dimensional space. devoted to time-domain analytical calculus reflection and transmission operators that are expressed terms Mittag-Leffler funct...

In the paper, a new method for modelling trees at medium detail is presented. The method is based on a volumetric representation of trees, generated by an iterated function system (IFS). Alleviating the modeling restrictions of fractal techniques, extensions to the standard IFS are introduced. Practical aspects of modeling and rendering of trees, such as data structures and bounding volumes, ar...

This work presents a new approach to the multiresolution modeling of polygonal meshes. This approach is based on the theoretically well-established fractal image compression techniques. A polygonal mesh is represented as a fractal using an iterated function system (IFS). In this way, a level of detail can be obtained over a region of the mesh by successively iterating the IFS. The main advantag...
