Increasing demands for wearable energy sources and highly flexible, lightweight photovoltaic devices have stimulated the development of textile-structured solar cells. However, the former approach of wire-type solar cell fabrication, followed by weaving of these devices, has had limited success, due to device failure caused by high friction forces and tension forces during the weaving process. ...

Enterprise organizations use Data Warehouses (DWHs) to analyze their performance. Performance is judged regarding the achievement of goals. DWH data models are well established. There exist numerous domain-specific modeling approaches. Enterprises also often model their goals in terms of formal or semiformal goal models. The problem is that these two aspects the Data Warehouse and the Enterpris...

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...

partial frames provide a rich context in which to do pointfree structured and unstructured topology. a small collection of axioms of an elementary nature allows one to do much traditional pointfree topology, both on the level of frames or locales, and that of uniform or metric frames. these axioms are sufficiently general to include as examples bounded distributive lattices, $sigma$-frames, $ka...

The versatility of the textile weaving process has made it a popular method for producing structural composite preforms. Enhanced through-thickness strength by multi-layer weaving, good in-plane strength and the ability to produce 2.5D or 3D shapes, are some of the advantages which have made weaving the most commonly used textile process for composite applications. It is also possible to incorp...

One source of vehicle conflict is the freeway weaving section, where a merge and diverge in close proximity require vehicles either entering or exiting the freeway to execute one or more lane changes. Using accident data for a portion of Southern California, we examined accidents that occurred on three types of weaving sections defined in traffic engineering: Type A, where every merging or dive...

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...
