Bozhong A Oilfield is located in the northeast of Huanghekou Sag Bohai Bay Basin, and a complex fault block oilfield. The main oil bearing horizon lower Minghuazhen Member, belonging to shallow water delta sedimentation. For rolling exploration evaluation adjacent blocks, this paper uses mudstone smear method analyze accurately characterize lithological contact relationship between two walls fa...

Introduction: Quaternary basalts are one of the last signs of magmatism in Iran, some of which are related to deep fractures and active faults in the Quaternary. Quaternary basalts of Tabas are very important due to their high expansion and location in eastern Iran, and are located 140 km south east of Tabas city and according to the proposed divisions are part of the Lut zone. The aim of this...

coupled -shear walls are one of lateral load resisting systems in high and medium rise reinforced concrete buildings. the lateral structural response is exactly dependents on the shear walls behavior; therefore these elements must response well whenundergodifferent load conditions. the structures located in near-source region behave differently compared to those in near-source sites when subjec...

This project is a continuation of MOU 373. It concludes ongoing research to extend and integrate existing results on fault diagnostic and fault management research, and develop a comprehensive fault management system. Features include a multi-layer fault diagnostic and management system, diagnosis of faults in the sensors and actuators of the lateral and longitudinal control systems, detection ...

interferometric synthetic aperture radar (insar) technique is valuable tool in monitoring crustal deformation due to its large spatial coverage and high spatial resolutions. in this paper, the intersiesmic crustal deformation occurred before earthquake on august 2012 in ahar-varzegan located in north-west of iran is studied using persistent scattering interferometry. the psi algorithm used in t...

Abstract On 15 May 2020 an Mww 6.5 earthquake occurred beneath the Monte Cristo Range in Mina Deflection region of western Nevada. Rapid deployment eight temporary seismic stations enabled detailed analysis its productive and slowly decaying aftershock sequence (p=0.8), which included ?18,000 autodetected events 3.5 months. Double-difference, waveform-based relative relocation 16,714 earthquake...

introduction iran forms a relatively compact zone of active continental deformation resulted from the northward collision of arabia with eurasia during late cenozoic times, which is continuing to the present-day at a rate of 25 mm/yrs (from gps data). evidences of active tectonic in different parts of iran, has been studied and identified. the arid climate, low rates of erosion, and minimal veg...

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 ...

This paper presents a novel fault detection and isolation (FDI) architecture applied to the lateral-directional axis of an F-14 aircraft during powered approach to landing under sensor failures. The fault-tolerant architecture employed is based on the so-called “Robust Multiple-Model Adaptive Control” (RMMAC) and hence is referred to as “RMMAC/FDI”. The results demonstrate successful stability ...
