Pipes are widely used in many industrial and mechanical applications and devices. Although there are many different constructions according to the specific application and device, these can show helical pattern, such as spiral pipes, wire-reinforced pipes/shells, spring-suspension, and so on. Theoretical modelling of wave propagation provides a prediction about the dynamic behavior, and it is f...

The classification of helical structures is of fundamental importance in several domains including natural sciences, engineering and medicine. Helixes are complicated structures to separate due to their highly non-linear temporal nature. Several studies have examined the famous two-spiral problem using several types of neural architectures. It has been observed that neural networks can be relia...

Over the past few years there has been growing interest in helical magnetic field structures seen at the solar surface, in coronal mass ejections, as well as in the solar wind. Although there is a great deal of randomness in the data, on average the extended structures are mostly left-handed on the northern hemisphere and right-handed on the southern. Surface field structures are also classifie...
