A microwave measurement system is utilized for the determination of displacement of a piston in a fluid filled cylindrical structure. The proposed ASRS server system and method is characterized by the use of a point-to-point multiplex communication interface, such as a TCPIP communication interface, instead of SQL server as in the case of the prior art, for performing data transmission between the control platform and the main server. A connecting member is secured to the capsule, and is adapted to be secured to a prey species such that when the prey species is released in a body of water, such as a lake, in the vicinity of the predator species, the predator species is likely to consume the prey species along with the capsule and shortly thereafter dies, thereby reducing the number of predator species. A computational model then may be utilized to determine one or more correction factors to compensate for the RRO. The first tapered end portion includes a first predetermined embossment.
