14C-dated Holocene coastal uplift, conventional and satellite geodetic measurements, and coseismic and aseismic fault slip reveal the pattern of distributed deformation at Taiwan resulting from convergence between the Philippine Sea plate and Eurasia; as in other subduction orogenic settings, the locus of strain release and accumulation is strongly influenced by changes in fault geometry across...
During recent years, landslide incidence has been increased in different areas with different reasons like change in land use and road introduction. It is necessary to research and survey that’s creation factors and identity sensitive areas to prohibit of probable damages. For this reason, This study were carried out in Northern of Tehran watershed with about 42.14 km2 area. In order to landsli...
Lake Urmia in northwestern Iran is one of the hypersaline lakes of world. In the Urmia region a Cenozoic island arc was formed by northeastward subduction of Neo-Tethyan oceanic plate beneath central Iran; the lake is therefore located in the fore-arc basin tectonic setting. Satellite imagery of the Urmia region illustrates that the trend of faults are in two main NE-SW and NW-SE directions. Th...
This paper proposes an on-line neural network based Distributed Static Compensator (DSTATCOM) for a three-phase, three-wire grid connected distribution system to mitigate the voltage flicker. The technique is based on instantaneous tracking of the voltage envelope and phase angle using online neural network based estimator. These estimated values are used by neural controllers to compute inputs...
Present Federal regulations which specify maximum instantaneous circuit breaker settings for the short-circuit protection of coal mine trailing cables are discussed. Characteristics of mine power systems, which limit short-circuit current in dc trailing cables and minimum expected short-circuit currents for dc 300 and 600 V trailing cables, are analyzed. New maximum instantaneous circuit breake...
[1] Two fore‐arc magmatic belts exist in Kodiak Island, the granitic Kodiak batholith and the basaltic trenchward belt. Both are part of the 2100 km long Sanak‐Baranof belt, interpreted to result from trench‐ridge‐trench (T‐R‐T) triple‐junction migration. In this hypothesis, trenchward belt basaltic rocks formed as the spreading ridge first entered the accretionary prism, and the larger Kodiak ...
The reliability of the transformer differential protection is under threat from multiple interferences, including inrush condition, current saturation and arc fault condition. For improvement, a new method proposed to discriminate conditions other non-fault conditions. Firstly, identifies unidirectional via index, since only it exhibits characteristic. Then, remaining signals are classified by ...
Two tectonic scenarios have been proposed for genesis and emplacement of the Oman ophiolite. One suggests that the ophiolite was generated at a spreading center, the other suggests generation within an intraoceanic arc. An integrated thermal and kinematic model of the temperature, stress, rock type, and displacement fields during early stages of the emplacement ofthe Oman ophiolite was develope...
