Active deformation in Alborz range is due to N-S convergence between Arabia and Eurasia. This paper provides geomorphic traces of regional deformation in NW Iran in order to characterize active faulting on major faults. Soltanieh and North Zanjan fault systems are involved in convergence boundary extent between South Caspian Basin and Central Iran. Soltanieh and North Zanjan faults are major re...

This work investigates the effect of the explicit inclusion of queueing delays due to locking overhead in a performance study of a two phase locking concurrency control method. A mean value analysis is used to calculate the system's performance measures, response time and throughput. It is found that the locking overhead's contribution to delay depends largely on the degree of page faulting act...

We have compared aftershock patterns following several moderate to large earthquakes with the corresponding distributions of coseismic slip obtained from previous analyses of the recorded strong ground motion and teleseismic waveforms. Well-located aftershock hypocenters are projected onto the main shock fault plane, and their positions are examined relative to the zones of coseismic displaceme...

The protocol with RJS at UCLA requires that all programs and data to be transmitted on the data connection be blocked[2]. This means that we simulate records and blocks with special headers. This we found to be another problem because of the computation and core space involved. This computation took an appreciable amount of time and core space we found because of our real core size that we were...

We consider how a persistent programming language might offer performance competitive with that of non-persistent languages, at least on memory resident data. We are concernedwith object-oriented languages, and with implementing persistence via object faulting, where the system detects uses of non-resident objects and fetches them on demand. We present some background on object faulting and mea...

The characteristics of near-fault ground motion are investigated considering heterogeneous slip distribution on the fault plane. Areas on the fault plane with large slip in compare with the average slip on the fault are known as asperity. The characteristics of strong ground motions in near-fault area are strongly affected by faulting parameters such as asperity location, maximum slip of asperi...
