abstract nowadays, with the partial achievement of the global village together with the hegemonic role based on western technology, the culture and of course the style of writing of developing countries (like our own), are at risk of being threatened. in order to maintain their style of writing, these countries must analyze their style and with the help of pathology and by keeping it up to date...

The Thomson’s Theorem states that static charge distributions in conductors show up at the conducting surfaces in an equipotential configuration, so that the electrostatic energy is a minimum. In this work we study an analogue statement for magnetic systems: in a given set of conductors, the stored magnetic field energy reaches the minimum value for superficial current distributions so that the...

application of quantum-dot is a promising technology for implementing digital systems at nano-scale.  quantum-dot cellular automata (qca) is a system with low power consumption and a potentially high density and regularity. also, qca supports the new devices with nanotechnology architecture. this technique works based on electron interactions inside quantum-dots leading to emergence of quantum ...

throughout prehistory, the cultures of iran and western asia differed in important respects. many of these differencescan be attributed to the different geographic and environmental conditions in the two regions. western iran is largely aheavily divided mountainous region with difficult access whereas mesopotamia is relatively flat and open to travel andtrade. the early holocene environment of ...

this paper presents a fault location technique for transmission lines with minimum current measurement. this algorithm investigates proper current ratios for fault location problem based on thevenin theory in faulty power networks and calculation of short circuit currents in each branch. these current ratios are extracted regarding lowest sensitivity on thevenin impedance variations of the netw...

Abstract In this paper, a 2D angle amplifier based on peristrophic multiplexed volume Bragg gratings is designed and prepared, in which calculation method firstly proposed to optimize the number of channels minimum. The induction multiplexing reduces performance difference one bulk grating, whereas there no need deliberately fabrication process. It revealed that discrete deflection range ±30° o...
