abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
آنتن های زیادی با سطح مقطع استوانه ای وجود دارند که در کنار یا روی آنها تعدادی عنصر تابنده با طول محدود وجود دارند. این ساختارهای تقریبا استوانه ای را می توان با روش s2ds(spectrum of two dimensional solutions) تحلیل نمود. به این ترتیب که با استفاده از تبدیل فوریه نسبت به محور استوانه (محور z )، مسئله الکترومغناطیس سه بعدی اینگونه آنتن ها را می توان بصورت عکس مسائل دو بعدی با تغییرات ها...
in this paper two nodes to model isotropic and anisotropic media in transmission line matrix method (tlm) are presented. by using these two nodes, the permeability and permittivity of an anisotropic media can be modeled simultaneously. another application of these nodes is in modeling media with permittivity and permeability less than one. in the conventional 2 dimensional tlm, the stubs repres...

The frequency-dependent characteristics of microstrip planar circuits have been previously analyzed using several full-wave approaches. All those methods directly give characteristic of the circuits frequency by frequency. Computation time becomes important if these planar circuits have to be studied over a very large bandwidth. The transmission line matrix (TLM) method presented in this paper ...
This paper presents a new approach for the modelling of a screw shaft including the axial and torsional dynamics in the same model. The model includes the distributed parameter dynamics of the ball screw system and the effect of mass distribution. This is based on the flexibility of the Transmission Line Matrix Method (TLM) to develop lumped and distributed parameter systems. The procedure for ...

one of the most important number sequences in mathematics is fibonacci sequence. fibonacci sequence except for mathematics is applied to other branches of science such as physics and arts. in fact, between anesthetics and this sequence there exists a wonderful relation. fibonacci sequence has an importance characteristic which is the golden number. in this thesis, the golden number is observed ...
