Ballistocardiographic observations.
Although it has long been known that body movement occurs with each heart beat (Gordon, 1877), and in spite of great progress during recent years, the value of ballistocardiography as a diagnostic aid remains uncertain. The object of the present investigation was to assess its clinical value utilizing a direct body-type displacement ballistocardiograph. In addition, the effects of the inhalatio...

متن کاملPattern Search Algorithms for Surface Wave Analysis
In recent years Rayleigh waves have been used increasingly as a nondestructive tool to obtain near-surface S-wave velocity, one of the key parameters in environmental and engineering applications (Miller et al., 1999a, 1999b; Park et al., 1998, 1999; Xia et al., 1999, 2003; Foti et al., 2002; Beaty and Schmitt, 2003; Tian et al., 2003; Zhang and Chan, 2003; Lin and Chang, 2004; O’Neill et al., ...
متن کاملSecond Harmonic X-wave Generation
In the process of optical second-harmonic generation an X-wave, travelling at the group velocity of the fundamental frequency, spontaneously forms. Its parameters, as well as the angular spectrum, are directly correlated to the group velocity mismatch and to the wavevector mismatch between the two harmonics. A novel mechanism for spatio-temporal localized waves generation is thus proposed. ∗Ele...
متن کاملSecond Harmonic Reduction of Traveling Wave Tube Amplifier Using Ferrite Material
Traveling Wave Tubes (TWTs) consist of different elements. The most important element of TWT is the RF circuit. RF circuits in helix TWTs need a dielectric support to hold the helix; this support also has an effect in electromagnetic properties of RF circuits. A novel dielectric support is proposed to reduce the second harmonic of helix TWTs. The dielectric support in this structure consists of...
