Structural textile pattern recognition and processing based on hypergraphs

The humanities, like many other areas of society, are currently undergoing major changes in the wake of digital transformation. However, in order to make collection of digitised material in this area easily accessible, we often still lack adequate search functionality. For instance, digital archives for textiles offer keyword search, which is fairly well understood, and arrange their content following a certain taxonomy, but search functionality at the level of thread structure is still missing. To facilitate the clustering and search, we introduce an approach for recognising similar weaving patterns based on their structures for textile archives. We first represent textile structures using hypergraphs and extract multisets of k-neighbourhoods describing weaving patterns from these graphs. Then, the resulting multisets are clustered using various distance measures and various clustering algorithms (K-Means for simplicity and hierarchical agglomerative algorithms for precision). We evaluate the different variants of our approach experimentally, showing that this can be implemented efficiently (meaning it has linear complexity), and demonstrate its quality to query and cluster datasets containing large textile samples. As, to the best of our knowledge, this is the first practical approach for explicitly modelling complex and irregular weaving patterns usable for retrieval, we aim at establishing a solid baseline

Bedouin textiles of Saudi Arabia

During the past year I have had the opportunity of working closely with a collection of Saudi Arabian woven textiles and other crafts. These textiles are characterized by the combination of a great variety of techniques, indicating a diffusion of techniques between the Arabian Peninsula and adjacent cultures. The frequent combination of both warp-faced and weft-faced structures within a single woven piece is particularly fascinating, as it rarely occurs in other cultures. This thesis will research the techniques and designs used in Saudi weaving and in the weaving of adjacent and related cultures in Africa and the Middle East which historically have had exchange with the Arabian Peninsula. It will focus particularly on the occurrence and diffusion of combined warp- and weft-faced textiles; it will attempt to examine the relationship between these structures and the technologies used to produce them, and between technology and other ethnological factors in a given region; it will attempt some conclusions about why these textiles occur where they do. The research will be elucidated where necessary with illustrations and maps

Connecting the Art of Navajo Weavings to Secondary Education

The Navajo Nation is well-known for its exceptional artistry with respect to the weaving of rugs, blankets, and other textiles. This article will discuss the culture of the Navajo, their weavings, and how this art form can be used to teach and extend mathematics concepts in secondary education. The patterns within the Navajo weavings will be used to illustrate examples of the four isometries and the seven frieze groups. These patterns will also be used to determine the fundamental region, as well as to study the fractal concept of iteration and its impact on area and perimeter

Inter-industry labor mobility in Taiwan, China

Do flexible labor markets lubricate growth? Using data from Taiwan, China, to analyze the effects of labor market flexibility, the authors find that: 1) Workers are more likely to move to industries that tend to be similar to their industry of origin (including intrasectoral moves that would be considered intersectoraal if there were more sectoral disaggregation). The degree of similarity between two industries is measured in several ways, all of them based on the input-output flows across industries. Workers are more likely to move from industry"i"to industry"j"if"i"supplies a large share of"j's"inputs, receives a large share of its inputs from"j,"or uses many of the same inputs. 2) Moves to more similar industries produce larger wage gains. This is especially true when the industries'similarity is based on their using many of the same inputs. Thid may be partly because the close proximity of industries, occupations, and individuals provides an environment in which ideas flow quickly from person to person. 3) Gains are more likely to accrue to industries as a result of labor mobility.Labor Policies,Water and Industry,Health Monitoring&Evaluation,Public Health Promotion,Environmental Economics&Policies,Water and Industry,Health Monitoring&Evaluation,Environmental Economics&Policies,Industrial Management,Banks&Banking Reform

"The Role of Tradition in Japan's Industrialization: A Perspective of "Indigenous Development""

This paper explores Japan's industrialization from the perspective of "indigenous development", focusing on what may be identified as "traditional" or "indigenous" factors. First, we describe the typical indigenous development process by looking at a case study of one rural weaving industry. After that, we investigate the functions of various institutions supporting "indigenous development" in modern Japan. Through these, we conclude that the peculiar logic functioning on the supply side of the developmental trajectory was the key to understand the existence of "indigenous development" in Japan's industrialization process. The existence of the household economy practicing a "rational" labour allocation strategy among household members within the framework of the traditional institution of the ie regulated behavior on the labour side. The measures and institutions run by the central and local governments supported the organization and market adaptation on the management side. Regional society also functioned to stabilize the relation between labour and management. All these factors worked to construct the system. Since each of the factors, including the intensity of labour inputs with relative low wages within peasant and small business households, and the benefits from a division of labour generated by this style of organization, contributed to competitiveness in the market, this system could have functioned as the basis of indigenous development.
