Abstract Double sequences appear in a natural way cases of iteratively given if the iteration allows to determine besides successors from predecessors also their followers. A particular pair double is considered which appears parqueting-reflection process complex plane. While one end each sequence number sequence, other consists rational numbers. The numbers are not yet listed OEIS Wiki. Comple...

Background. The double haul is a unique feature of single-handed fly casting and is used in both fly fishing and fly casting competition. The movement behaviour during the double haul has not been investigated in previous research. Objectives. Describe the coordination of the rod and line hauling movements during distance fly casting. Methods. Elite fly casters performed distance castin...

This study is about neutrosophic structures, which one of the popular topics recent days. In this study, different types convergence concepts were applied to difference sequences. With help properties double type sequences, concept sequences combined with structures that are advantageous work like Lacunary
