Aspect-orientation is a relatively new paradigm that introduces abstractions to modularize the implementation of system-wide policies. It is based on a composition operation, called aspect weaving, that implicitly modifies a base system by performing related changes within the system modules. Aspect-oriented graph grammars (AOGG) extend the classic graph grammar formalism by defining aspects as...
The worldwide annual production volume of textiles is nearly one hundred million metric tons. Most of these undergo treatments to achieve specific properties, such as color, hydrophobicity, antimicrobial, or UV protection, using chemicals that lead to collateral environmental consequences. There is great interest in developing alternative and sustainable strategies to achieve textile functional...
BACKGROUND Musculoskeletal disorders (MSDs) are a common problem among carpet weavers. This study was undertaken to introduce affecting personal and occupational factors in developing the number of MSDs among carpet weavers. METHODS A cross-sectional study was performed among 862 weavers in seven towns with regard to workhouse location in urban or rural regions. Data were collected by using q...
Textile manufacturing is a major industry in India. It is based on the conversion of three types of fibre into yarn which in turn is woven into fabrics. Fabrics are textile materials which are made through weaving ,knitting, braiding and bonding of fibres. Weaving is described as inter-lacing of two distinct set of threads to form cloth, rug or other type of woven textile. The lengthways thread...
Background: Carpet weaving is an occupation that requires sufficient and appropriate lighting. The lighting in carpet weaving workshops affects the productivity and the physical and mental health of workers. Therefore, the evaluation of the illumination and the identification of work stations requiring lighting modifications will be helpful in promotion of the health and safety of workers in ca...
Introduction: Due to their long work hours at environments with poor lighting, carpet weavers are at a risk of developing certain eye diseases. Improving health conditions and safety in the workplace, in particular supplying good lighting to carpet weaving workshops as an important environmental factor, is crucial to the health of carpet weavers. Materials and Methods: The present desc...
A study of various deficiencies observed in the process of pile carpet weaving in the Province of Kashan has revealed that the most important defects are: unevenness, crimpled sides and erroneous application of the cartoon. Improving weavers’ skills will have a significant effect on reducing these defects. Therefore, weavers should be given educational advice on recognizing the capabiliti...
In many FEM applications, hexahedral meshes are necessary to get the best results. However the automatic generation of an hexahedral mesh from an arbitrary 3D geometry still remains a challenge. In this paper, we propose an extension of the reliable Whisker Weaving algorithm [6]. The Whisker Weaving algorithm starts from a pre-meshed quadrilateral surface, it generates hexahedral meshes for a l...
