Interferometric SAR data should be filtered in order to remove the geometrical decorrelation caused by the presence in the signal pair of “incoherent” components not illuminated in both the passes. This operation is generally carried out, via common band filters, by assuming a planar topography whereas in the real, non-planar topography case, the problem becomes space variant. We discuss the ap...

the zagros fold- thrust belt as a part of alpine- himalayan orogenic belt, is one of the most active continental collision zones on the earth, which extends from the tarus mountains in south eastern turkey to the minab fault in the east of the strait of hormoz in southern iran. structurally, its formation is related to the continuing convergent movement between the arabian plate to the southwes...

We study adaptive system-level fault diagnosis for multiprocessor systems. Processors can test each other and future tests can be selected on the basis of previous test results. Fault-free testers give always correct test results, while faulty testers are completely unreliable. The aim of diagnosis is to determine correctly the fault status of all processors. We present adaptive diagnosis algor...

Fluid injection into rocks is increasingly used for energy extraction and for fluid wastes disposal, and can trigger/induce small- to medium-scale seismicity. Fluctuations in pore fluid pressure may also be associated with natural seismicity. The energy release in anthropogenically induced seismicity is sensitive to amount and pressure of fluid injected, through the way that seismic moment rele...

We consider bimodal linear control systems consisting of two subsystems acting on each side of a given hyperplane, assuming continuity along the separating hyperplane. For a differentiable family of controllable planar ones, we construct a differentiable family of feedbacks which pointwise stabilizes both subsystems.

Planar laser-induced fluorescence (PLIF) images of hypersonic flow over a wedge are compared with a theoretical PLIF model. The synthetic images, which include the effects of collisional quenching, are based on a perfect-gas treatment of the fluid mechanics, assuming frozen chemistry. We find very good agreement between the model and the experimental measurements.

We consider the wave equation with a damping term on a partially rectangular planar domain, assuming that the damping is concentrated close to the non-rectangular part of the domain. Polynomial decay estimates for the energy of the solution are established.

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....

Conventional position sensors for permanent magnet synchronous motor, such as optical encoder, resolver, or hall sensor, can get fault by the stress. The of motor sensor may cause serious accidents. Thus, to prevent damages failure, adding a redundancy wound search coil is recommendable. In this paper, new planar design that be used proposed. This based on flexible-printed circuit board convert...
