We developed a kinematic earthquake cycle model applicable to transform fault zones, subduction zones, and collision zones on the basis of elastic dislocation theory. The crustal deformation associated with the periodic occurrence of interplate earthquakes is generally given by the superposition of viscoelastic responses to steady slip on the whole plate boundary, steady back slip on the seismi...

A skilled string performer is able to play a series of spiccato notes (short strokes played by a bouncing bow) with each onset showing little or no aperiodic motion before a regular slip/stick pattern (Helmholtz motion) is triggered. Kinematic analysis reveals that a well-behaving bow gives nearly vertical impacts on the string, and that the first slip of each note takes place when the normal b...

We investigate the tuning behavior of a novel type of single-frequency optical synthesizers by phase comparison of the output signals of two identical devices. We achieve phase-stable and cycle-slip free frequency tuning over 28.1 GHz with a maximum zero-to-peak phase deviation of 62 mrad. In contrast to previous implementations of single-frequency optical synthesizers, no comb line order switc...

in this paper the factor of safety (fs) and critical line-segments slip surface obtained by the alternating variable local gradient (avlg) optimization method was presented as a new topic in 2d. results revealed that the percentage of reduction in the fs obtained by switching from a circular shape to line segments was higher with the avlg method than other methods. the 2d-avlg optimization meth...

the majority of existing tractors in iran are not equipped with any tools to measure and display slip and ground speed. this is mainly due to the lack of national standards for measuring tools and instruments of tractors. in current research, an interchangeable system for two wheel drive tractors has been designed. furthermore, it has been assessed after construction. to measure actual and theo...

Sequences of dynamic instabilities are analyzed for a single degree of freedom elastic system which slides along a surface having frictional resistance depending on slip rate and slip rate history, in the manner of Dieterich, Ruina and others. The system is represented as a rigid block in contact with a fixed surface and having a spring attached to it whose opposite end is forced to move at a u...

Slow slip events (SSEs) detected on the Cascadia Subduction Zone interface at 30–50 km depth imply a release of accumulated strain. However, studies interseismic deformation in typically find coupling upper 30 interface, which is generally accepted as defining seismogenic zone. Estimates using net velocities (including SSE effects) and restricting to shallow may underestimate deficit accumulati...
