Repeat Pattern

This study explored the patterning abilities of eight children between the ages of four and five-and-a-half. Task-based interviews were conducted where children were required to produce their own repeat pattern, to copy and extend a given repeat pattern, and complete missing parts of a repeat pattern. The findings show that most children were able to copy and extend a pattern, but few could produce their own repeat pattern. While most children tended to focus on “what comes next”, some children paid attention to pattern structure, but were not able to isolate the pattern element.

Paper Folding

Historically, Japanese traditional lampstand 'Andon', was manufactured from paper. And paper folding method was adopted into some Andon or western lampshade design. For example, Yoshimura/Diamond pattern, known as a structure of crashed cylinder, or a structure of building roof, that has been of beneficial use in commercial lampshade products. Yoshimura pattern structure includes a set of skew quadrilaterals which are not on a plane surface and each quadrilateral is constructed with 2 planar triangles. Development of Yoshimura pattern is constructed by one set of horizontal parallel lines at even intervals for valley fold and two sets of oblique parallel lines at even intervals for mountain fold. The author found that similar shape can be constructed from development which includes only mountain fold lines of Yoshimura pattern and this method has various applications. With proposed paper folding method, each skew quadrilateral is constructed by single curved surface. In this paper, the author first defined the principle of the proposed paper folding method, second, explained the. features of the shape made by the proposed method and the luminance distribution on the shape, third, indicated examples of applications of the proposed method. Finally, examples of application of the shape made by SQMF in the field of education are explained.

Standardized pattern representations have become a popular way to capture, classify, and communicate the essential characteristics of software designs. Both books and large Web sites serve as pattern repositories for use by software design engineers. Because they are usually expressed in verbal and diagrammatic form using, say, UML, they are susceptible to ambiguities and the consequent misinterpretation. The goal of this chapter is to illustrate how to represent rigorously Design patterns, in order to avoid this problem, and to analyze the capabilities of this technique. It describes a more formal, logic-based language for representing pattern structure and an extension that can also represent other aspects of patterns, such as intent, applicability, and collaboration. This mathematical basis serves to eliminate ambiguities. The chapter explains the concepts underlying the languages and shows their utility by representing two classical patterns, some concurrent patterns, and various aspects of a few other patterns.

Machine fault classification is an important task for intelligent identification of the health patterns for a mechanical system being monitored. Effective feature extraction of vibration data is very critical to reliable classification of machine faults with different types and severities. In this paper, a new method is proposed to acquire the sensitive features through a combination of local discriminant bases (LDB) and locality preserving projections (LPP). In the method, the LDB is employed to select the optimal wavelet packet (WP) nodes that exhibit high discrimination from a redundant WP library of wavelet packet transform (WPT). Considering that the obtained discriminatory features on these selected nodes characterize the class pattern in different sensitivity, the LPP is then applied to address mining inherent class pattern feature embedded in the raw features. The proposed feature extraction method combines the merits of LDB and LPP and extracts the inherent pattern structure embedded in the discriminatory feature values of samples in different classes. Therefore, the proposed feature not only considers the discriminatory features themselves but also considers the dynamic sensitive class pattern structure. The effectiveness of the proposed feature is verified by case studies on vibration data-based classification of bearing fault types and severities.
