The fractal model can deliver the power of mathematics to be used in modeling the complex things that can be handled by computer programs. This paper delivers the short-cut way to design the artistic calligraphic characters based on the modification of the existing form of the simple rectangle fractal object to construct the stroke form of the calligraphic character as the simple solution of the inverse problem. The upright collage component design of rectangle fractal object can be decomposed into many cells of collage component of a calligraphic character with equal size in the right position of the cells according to the stroke of calligraphic character designed. The short-cut way to encode the fractal object is by copy-editing the representative IFS code based on the position of the cells according to the position of each component of the str...

The efficient way can be shown by the minimum number of steps and the minimum amount of energy consumption required by the rotation and spin operations of the degree of freedom mechanism. The minimum amount of energy consumption can be obtained not only by planning to choose the path with the minimum number of steps, but also it depends on the choice of the operation mode, in the rotating or spinning mode or in the combination of the rotating and spinning modes without overhead movements.

The code of iterated function systems of a fractal can be generated by composing the interrelated components in the collage composition design iteratively based on the collage theorem which is ruled by a set of self-affine transformations. The fractal result is displayed by means of the partitioned-random iteration algorithm as the decoding process of multi-object of fractals as the collection of the artistic characters. The number of the partition is set based on the number of characters in a composition of the artistic characters accordingly, so the individual self-affine transformation of a character can be modified independently.

For the sake of simplification, the segments of robot arm are represented as the collection of simple rectangle fractal connected to each other. The simulation of animation can be accomplished by non-metamorphic animation method based on the periodical manipulation of the IFS fractal object identity. The shifting centroid technique is the key to simplify the complexity of DoF mechanism.

The star-like object rotation effect in the IFS fractal model could be exhibited by using metamorphical method, as a replacement to the affine rotation method on a non metamorphic animation. The advantage of a metamorphic animation method over the metamorphic animation method is that the object's relative position to the fixed point as an absolute centroid is absolute. Therefore, the rotational effect can be exhibited at any positions. In addition, it can also be combined with rotational effect of the local centroid itself around the absolute centroid as a fixed point by the primitive rotational operation to form an interesting behavior of orbital trajectory Based on the hybrid of both animation methods, the animation simulation could be done on orbital trajectory on a twin stars rotating to each other as a system. Both objects are rotated in the same angular direction, ...

The metamorphic animation of fractal images can be constructed on more than two fractal images. The multi-transitional IFS code can represent the multiple fractal images as the iteration nodes of the cyclical animation. There is a solution needed to have the metamorphic animation of fractal images in IFS model with different number of transformation functions.

From the multi-object point of view, both the individual events are looked like as a single simultaneousevent such as in the rotational simulation of two rotating wheels as the front and rear wheels and a rotated wheelof the pedal wheel in a bicycle. The above rotational effect can be created by metamorphic animation methods onthe fractal object which has IFS code in rotational IFS code family. The identical but differ in position object canbe constructed by means of cloning technique and the identical but differ in size and position can be constructedby means of the cloning and scaling techniques. To accomplish the simulation of cycling event of a bicycle in thefractal model, a combination method between metamorphic animation on multi-object and object is proposed.

Beberapa jenis musik memiliki pengaruh menenangkan pikiran, bahkan musik dapat membantu mengurangi stres pada seseorang yang sedang dalam kondisi stres. Selain itu musik juga dapat meningkatkan mood seseorang, dan memberikan energi bagi pendengar. Salah satu perangkat yang dapat menangkap kondisi pikiran termasuk pengaruh rangsangan suara adalah Electroencephalogram (EEG), yang menangkap aktivitas listrik di otak. Namun analisis sinyal EEG tidaklah mudah, karena amplitudonya kecil sehingga mudah tertimbuh noise, dan tidak mempunyai bentuk yang baku. Penelitian ini membuat sistem yang dapat mengklasifikasikan sinyal EEG terhadap rangsangan suara menggunakan ekstraksi power spektral dan Jaringan Syaraf Tiruan Backpropagation dan mengklasifikasikan terhadap 3 kelas yaitu musik klasik, murotal Al-Quran dan musik rock.

In this way it is possible to create an attractive animation based on the combination of both animation methods as a generic animation method, as discussed in this paper. The proposed method can be used as an alternative for or as an extension of the existing animation methods in classical geometry, which are restricted to objects with regular forms.

Compared to the conventional animation, the fractal animation model is easier to be handled just by calling the rotation procedure for the satellite object around the planet object and the same revolution procedure around a fixed point for both objects with a certain parameter to determine the speed of rotation and revolution.

If the source and target image that represent the same circle-like fractal object are slightly different, then the metamorphic animation can exhibits the rotational and zooming effects. If the order of functions in the 2D IFS code of circle-like fractal as a node in the multitransitional IFS code differ compared to the next node by shifting one function, then the rotational effect is occurred. But if the order of functions in the 2D IFS code of circlelike fractal as a node in the multi-transitional IFS code differ compared to the next node by shifting more than one function, then the rotational and zooming effects are occurred.
