Various pressure vessels from Type I to Type IV are used to store hydrogen and compressed natural gas (CNG) at high pressures. The polymeric liner in Type IV composite pressure vessels (CPVs) does not share the load, unlike those with metallic liners (Type III); hence, the composite layers share the entire load. The winding angles play a crucial ro...

Blood oxygenators involve a complex network of hollow fibers for efficient gas exchange with blood. The optimal microstructural arrangement of these fibers is an ongoing research interest. While the fiber systems of commercial oxygenators are manufactured to address mass production, the research oxygenator prototypes demand more flexibility so that...

Multi-three-phase motor drives are experiencing a significant development among the multiphase solutions since they are configured as multiple three-phase units operating in parallel. Although the literature reports several torque controllers able to deal with multi-three-phase motors, most of them obtain high performance of torque regulation as lo...

Aging of high voltage generators and motors lead to changes in the dielectric properties of the stator winding insulation system. Research on the relation between aging and dielectric response has been going on for decades. A particular challenge is that the coil insulation consists of several materials: two that strongly affect the dielectric resp...
