Textile preforms are used as structural backbones in composite materials. They provide homogeneous distribution of fibers and matrix materials. Various techniques like weaving, knitting and braiding are used to make textile preforms from high performance fibers like carbon, glass and aramid. Woven preforms have advantages like design flexibility and net shape manufacturing but lower out-of-plane properties. Three-dimensional preforms have better in-plane and out-of-plane properties but their production is more complex. Optimization of textile production techniques can help reduce the manufacturing cost of composites using textile preforms.

The document discusses various spinning techniques, including rotor spinning. It provides a history of rotor spinning, describing its development from early prototypes in the 1950s to widespread commercial use by the 1970s. It explains the basic operational sequence of rotor spinning, which involves feeding a sliver of fibers into a rapidly rotating rotor that separates, compacts, and twists the fibers into yarn. The document compares properties of rotor-spun and ring-spun yarns.
Fancy Spinning
The document summarizes different types of specialty yarns including Bobtex, chenille, slub, siro, and core spun yarns. It provides details on the production processes, properties, and end uses of each yarn type. The Bobtex process produces an integrated composite yarn using a core of filaments or multifilaments covered with staple fibers and a polymer layer. Chenille yarn has a fuzzy surface due to short cut pile yarns wrapped around a core. Slub yarn is produced with intentional thicker and thinner sections. Siro spinning combines spinning and twisting in one step to make a two-fold yarn. Core spinning covers a core yarn, typically filament,

Embedded machine learning-based road conditions and driving behavior monitoring
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.
