Systems and methods for fabrication of composite shell elements and to the assembly of large scale structures comprising such composite shell elements are provided. A first channel formation region and a second channel formation region contain different materials as their respective main components. A computation device reconstructs 3D volume data from the image data based on projection parameters and based on the position andor orientation of the moving section of the examination object. The third circuit receives a feeding voltage from the second circuit for feeding the third circuit. In a first state, the second ring is non-rotatable relative to the first ring in both the opening and closing directions, and in a second state the first and second rings are rotatable about the body, and the second ring is rotatable relative to the first ring in the closing direction. The novel interconnect structure has enhanced liner and seed conformality and is therefore capable of delivering improved device performance, functionality and reliability.
