[1] The Vienna Basin at the transition between the Alpine and Carpathian belt hosts a number of large Pleistocene sub-basins forming along an active continental scale strike-slip fault (Vienna Basin strike-slip fault). We utilize first-order derivatives from industrial Bouguer gravity data to unravel the impacts of Pleistocene kinematics on the Vienna Basin and to compensate for the lack of nea...

[1] We combine a viscoelastic model for the interseismic process and an elastodynamic model for the coseismic process to explore the dynamics (over multiple earthquake cycles) of two parallel strike-slip faults embedded in a two-dimensional full space. The step over fault geometry results in a buildup of heterogeneous fault stress near the step over. This heterogeneous stress accumulates at the...

in this study, the 2005 dahuieh (zarand) locally recorded aftershock sequence has been analyzed. having the distribution of aftershocks and the source extension, a w-e trending near vertical faulting with an extension of about 15-20 km could be estimated. the rupture causing the powerful dahuieh earthquake apparently initiated in the modified epicentric area and propagated unilaterally towards ...

Local seismic arrays were deployed at two locations along the San Andreas fault (SAF) near Parkfield, California, before and after the 2004 M 6.0 Parkfield earthquake. Using local earthquakes we determine the anisotropic field within 1– 2 km of the main trace of the SAF at the two array locations separated by 12 km. The initial array, near the SAFOD site, was deployed for six weeks in October a...

سازه هایی که در حاشیه گسل های فعال واقع می شوند باید برای شرایط متناظر طراحی شوند. لذا برای این سازه ها، اثر گسل های نزدیک(near fault) به عنوان منشاء، یکی از تحریک های مهم منظور می شود. جالب است که در دهه اخیر تعداد قابل ملاحظه ای از رکورد زلزله در فواصل بسیار نزدیک به خط یا ناحیه گسل ثبت شده است. به عنوان مثال می توان به رکوردهایی از زلزله های نورثریچ (northridge,1994)، کوبه (kobe,1995) چی-چی ...

In this paper a simple model of a three story building with inclined first-story columns has presented. The stories are supposed to be rigid and are connected to axially rigid mass less columns by elasto-plastic rotational springs and linear rotational dampers. The considered model is subjected to horizontal component of fault normal pulse with different magnitudes and the governed nonlinear di...

This paper proposes a novel scheme for detecting and classifying faults in stator windings of a synchronous generator (SG). The proposed scheme employs a new method for fault detection and classification based on Support Vector Machine (SVM). Two SVM classifiers are proposed. SVM1 is used to identify the fault occurrence in the system and SVM2 is used to determine whether the fault, if any, is ...

BACKGROUND Disclosure of near miss medical error (ME) and who should disclose ME to patients continue to be controversial. Further, available recommendations on disclosure of ME have emerged largely in Western culture; their suitability to Islamic/Arabic culture is not known. METHODS We surveyed 902 individuals attending the outpatient's clinics of a tertiary care hospital in Saudi Arabia. Pe...
