چکیده
THE RESPONSE of hitherto known practical forms of seismographs depends upon the relative motion of a pendulum and the moving ground to which ~ts supporting structure is fastened. The various kinds of seismographs differ in the type of pendulum used, such as gravity, spring, torsion, and/or they differ in the type of magnifying and recording elements which they employ. They all measure or indicate the vibratory motion of the ground at a giver point. In

Observations of Love and Rayleigh waves on WWSSN and Canadian Network seismograms have been used to place constraints upon the source parameters of the August 1, 1975, Oroville earthquake. The 20-sec surface-wave magnitude is 5.6. The surface-wave radiation pattern is consistent with the fault geometry determined by the body-wave study of Langston and Butler (1976). The seismic moment of this e...
متن کاملThe Society of the Spectacle Revisited: Separation, Schooling, and the Pursuit of Dangerous Citizenship
In this paper we set out to accomplish several goals. Primarily, we seek to re-interpret Guy Debord’s (1967) work The Society of the Spectacle in light of modern-day schooling, principally within North America (although we recognize the global connectivity inherent in any current discussion of formal education). In addition, we aim to utilize Debord’s conceptualizations as a series of means and...
متن کاملAn Investigation of the Generic Features of Research Articles Published in the Bulletin of Iranian Mathematical Society
In light of the understanding that the analysis of the generic features of different academic genres can enhance the ability of non-native members of academic discourse communities to understand, and where appropriate, to produce them, the present study aimed at investigating the dominant generic structure of research articles in mathematics. To start with a relatively narrow focus, a corpus of...
متن کاملAnalysis of rock-fall and rock-fall avalanche seismograms in the French Alps
This study reviews seismograms from 10 rock-fall events recorded between 1992 and 2001 by the permanent seismological network Sismalp in the French Alps. A new seismic magnitude scale was defined, which allowed us to compare and classify ground-motion vibrations generated by these Alpine rock-falls. Each rock-fall has also been characterized by its ground-motion duration t30 at an epicentral di...

Near-source ground motion at four azimuths but constant epicentral range 1s computed from a buried circular strike-slip fault in a half-space. Particle acceleration, velocity, and displacement at each station on the free surface is computed in the frequency band 0.0 to 5.0 Hz. The assumed dislocation is denved from the Kostrov (1964) displacement function for a continuously propagating stress r...
