A method for robotized cable winding of the Uppsala University Wave Energy Converter generator stator has previously been presented and validated. The purpose of this study is to present and validate further developments to the method: automated stand-alone equipment for the preparation of the winding cables. The cable preparation consists of three parts: feeding the cable from a drum, forming ...

The cable equation describes the voltage in a straight cylindrical cable, and this model has been employed to model electrical potential in dendrites and axons. However, sometimes this equation might give incorrect predictions for some realistic geometries, in particular when the radius of the cable changes significantly. Cables with a nonconstant radius are important for some phenomena, for ex...

The earliest industrial monuments in Britain are the Neolithic flint mines, dating to around 4000 bce . These mining shafts, which tunnel deep into chalk geologies, evidence extremes that ancient Britons were willing resort order obtain valuable raw materials. Numerous scholars, marvelling at excavation processes and hand tools used aid extraction of flint, have studied flint-mining industry. R...

The nearly 21-year-old Jiujiang Bridge, which is suffering from uneven line shape, constant great downwarping of the main beam and cracking of the box girder, needs reinforcement and cable adjustment. It has undergone cable adjustment for twice with incomplete data. Therefore, the initial internal force state of the Jiujiang Bridge is identified as the key for the cable adjustment project. Base...

A power cable is widely used for power supply in power distributing networks and power transmission lines. Due to limitations in the production, delivery and setting up power cables, they are produced and delivered in several separate lengths. Cable itself, consists of two cable terminations and arbitrary number of cable joints, depending on the cable route length. Electrical stress control is ...

OF THE DISCLOSURE A handling system with an improved fairlead is provided for protecting a tow cable wherein the cable breaking strength exceeds the system-rated tension load; the fairlead being positioned collinearly between the system bellmouth and winch. A guide slot passes through the fairlead positioning the cable higher than the winch release point and bellmouth entry point, maintaining t...

The smart cable with embedded distributed fiber optical Bragg grating (FBG) sensors was chosen as the object to study a new diagnosis method about broken wires of bridge cable. The diagnosis strategy based on cable force and stress distribution state of steel wires was put forward. By establishing bridge cable and cable steel wires model, the broken wires sample database was simulated numerical...
