Automatic Slider Type Knitting. Needle

Quantum Knitting

We analyze the connections between the mathematical theory of knots and quantum physics by addressing a number of algorithmic questions related to both knots and braid groups. Knots can be distinguished by means of ‘knot invariants’, among which the Jones polynomial plays a prominent role, since it can be associated with observables in topological quantum field theory. Although the problem of c...

Chronic impalement- Case report of a knitting needle 33 years’ ascension

BACKGROUND We report the case of a 72-year-old female complaining of hemoptysis due to a thoracic-abdominal knitting needle inserted 33 years ago for self-induced abortion. CASE PRESENTATION The PA/LL chest x-ray showed a metallic foreign body on thorax extending into the abdomen. An CT examination confirmed the transdiaphragmatic knitting needle extending from liver into right upper lobe. ...

Slider-Pinning Rigidity: a Maxwell-Laman-Type Theorem

We define and study slider-pinning rigidity, giving a complete combinatorial characterization. This is done via direction-slider networks, which are a generalization of Whiteley’s direction networks.

Constructive Knitting for Children

Knitting a 3D Model

A knitted animal is made of a closed surface consisting of several knitted patches knitted out of yarn and stuffed with cotton (Fig. 1). We introduce a system to create a knitting pattern from a given 3D surface model (mainly designed for rotund animal models). A knitting pattern is an instructional diagram describing how to knit yarn to obtain a desired shape. Since the creation of knitting pa...
