Electrothermal Twisted and Coiled Polymer Artificial Muscles and Their Applications in Soft Robotics
Small Structures, Volume 7, Issue 5, May 2026.Researchers develop a PE@SPN electrothermal polymer artificial muscle with a parallel‐stranded spiral structure. A temperature self‐sensing‐driven hierarchical closed‐loop fractional order PID (FOPID) control scheme is adopted. A rehabilitation manipulator was designed, and subsequently, a series of experiments are conducted to test the performance of ...

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility
International Journal of Urban and Regional Research, Volume 50, Issue 3, Page 644-666, May 2026.Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city's circulatory flows ...

Forming Process of Wire and Arc Additive Manufacture
Materials Science Forum, 2021The forming process of wire and arc additively manufacture (WAAM) was studied using the self-developed and designed WAAM system. The single-pass and single-layer weld bead samples were prepared with different process parameters, and the cross-sectional dimensions of the weld bead were measured.

Wire + Arc Additive Manufacturing of Metals
2020Wire + Arc additive manufacturing (WAAM) processes have become popular because of their proven capabilities to produce large metallic components with high deposition rates (promoted by arc-based processes) compared to conventional additive manufacturing processes such as powder bed fusion, binder jetting, direct energy deposition, etc. The applications

Trajectory Optimization for Wire-Arc Additive Manufacturing
2019We consider a technical operations research problem that arises in the wire-arc additive manufacturing process. In order to manufacture a three dimensional object, it is build layer-wise from bottom to top, where in each layer a metal wire is melted using high temperatures at a welding torch.

Laser enhancement of wire arc additive manufacturing
ICALEO 2018: 37th International Congress on Applications of Lasers & Electro-Optics, 2018Additive Manufacturing (AM) can be used for the fabrication of large metal parts, e.g. aerospace/space applications. Wire Arc Additive Manufacturing (WAAM) can be a suitable process for this due to its high deposition rates and relatively low equipment and operation costs.

Technological Processes for Wire Arc Additive Manufacturing
2023One of the most used technologies that has been rapidly developing in recent years is related to the application of 3D printing. Layer by layer luilding of details through selective remelting or sintering processes is based on different welding (or similar) processes. Metals, polymers and ceramics in the form of powder or wire are used as materials for
