We consider the problem of embroidering a design pattern, given by a graph G, using a single minimum length thread. We give an exact polynomial-time algorithm for the case that G is connected. If G has multiple connected components, then we show that the problem is NP-hard and give a polynomial-time 2-approximation algorithm. We also present results for special cases of the problem with various...

The garment manufacturing industry is a labor-intensive industry, with one of the slowest transitions to automation. Hence, it essential build smart factory based on automated systems improve productivity and allow responsive production in market. In this study, processes for sports bra were established optimized using various machines. For system, computer-based 3D virtual design software, tec...

A textile-based triboelectric nanogenerator (TENG) is an energy harvesting flexible and lightweight device that converts mechanical to electrical energy. This work presents characterization of a novel hybrid 3D printed embroidery TENG for harvesting. The digital part done on Brother Embroidery Machine PR670E with polyester multifilament conductive thread (CleverTex) linear resistance 280 Ω/m. f...

The integration of shape grammars within a generative system is thought to have good potential to support design applications in the art and cultural domains. Based on a shape decomposing method, two-level generative shape grammars are developed within the application of Zhuang ethnic embroidery design. In our approach, free B-spline curves are used to derive initial design concepts together wi...

, population statistics will still be grossly incorrect measures of IVF programme quality. Thirdly, attempts to feed the appetite of patients, politicians, and insurance companies for information on IVF programmes by the provision of statistical results summaries under the auspices of well-intentioned professional societies (or regulatory agencies) actually make the problem worse. This is becau...

Durable, electrically conducting yarns are a critical component of electronic textiles (e-textiles). Here, such yarns with exceptional wear and wash resistance are realized through dyeing silk from the silkworm Bombyx mori with the conjugated polymer:polyelectrolyte complex PEDOT:PSS. A high Young's modulus of approximately 2 GPa combined with a robust and scalable dyeing process results in up ...

In this study, we developed a feasible structure of a textile-based inductive sensor using a machine embroidery method, and applied it to a non-contact type vital sign sensing device based on the principle of magnetic-induced conductivity. The mechanical heart activity signals acquired through the inductive sensor embroidered with conductive textile on fabric were compared with the Lead II ECG ...
