             abstract = "Schenberg is a resonant-mass gravitational wave detector developed 
                         by the Brazilian Graviton group that is sensitive to a central 
                         frequency near 3200 Hz with bandwidth around 200 Hz. Its spherical 
                         antenna weighs 1150 kg and it is connected to the outer 
                         environment by a suspension system designed to attenuate local 
                         noise, both seismic and non-seismic. During the passage of a 
                         gravitational wave the antenna is expected to vibrate and such 
                         motion will be monitored by six parametric transducers whose 
                         electronic signal will be digitally analyzed. For the microwaves 
                         to reach the transducers, coaxial cables are needed, which are 
                         also connected to the outer environment and may be a source of 
                         seismic noise. Using the finite elements method, this work shows 
                         that the proper addition of masses along these cables reduces such 
                         seismic noise to levels below the detectors thermal noise when it 
                         operates at 50 mK, thus avoiding the decrease of the expected 
                         sensitivity of the detector.",
