Differential protection normally detects short circuits and ground faults in the windings of a power transformer its terminals. Inter-turn refer to flashovers among electrodes that arise only similar type physical winding. can be examined when adequate sum turns is served as short-circuited. In electrical protection, it difficult detect inter-turn faults. An fault small magnitude based on limit...

Considering hypothetical co-orbital asteroids with the Earth, Tatum (1997) presented a study about the necessary radial distance in order to produce collision. He adopted an analysis considering a composition of circular two-body systems, Sun-Earth and Sun-Asteroid. He found that asteroids with radial positions between 0.9943 and 1.0057 AU would necessarily collide with the Earth. In the presen...

The main aim of the distribution companies is to reduce their operating costs to get ahead of competition. One of the most popular approach is to increase the degree of reliability of distribution system. The management of network defeats (e.g. earth fault, short circuits) offers a lot of feasibilities for automation. The main jobs are fault localization, fault detachment and system refurbishin...

Most of the craters on the surface of the Moon were created by the collision of minor bodies of the Solar System, in particular asteroids coming from the Main Belt as a consequence of different types of resonance. Our aim is to investigate the dynamics of such asteroids, paying special attention on the hyperbolic invariant manifolds associated with the equilibrium point L2 of the Earth – Moon s...

the verses of the qur’ān apparently talk about the six-day creation of the heavens and the earth but the new science views the process of the formation of heavenly bodies and the earth in a longer time span and does not approve the formation of the universe in a period of a few days. thus, many of the contemporary qur’ān researchers have withdrawn from the formalistic and generally accepted (ma...

Fault tolerant circuits are currently required in several major application sectors. Besides and in complement to other possible approaches such as proving or analytical modeling whose applicability and accuracy are significantly restricted in the case of complex fault tolerant systems, fault-injection has been recognized to be particularly attractive and valuable. Fault injection provides a me...

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...

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...

Vertex connectivity and edge connectivity are two important parameters in interconnection networks. Even though they reflect the fault tolerance correctly, they undervalue the resilience of large networks. By the concept of conditional connectivity and super-connectivity, the concept of restricted vertex connectivity and restricted edge connectivity of graphs was proposed by Esfahanian [A.H. Es...
