This paper proposes a new method for transmission loss allocation. The share of each bus in the transmission line losses is determined using transmission line loss equations with respect to bus-injected currents. Then, it is applied to the total network transmission lines. In the proposed method, comparing with other methods, a solution to remove the negative loss allocation has been introd...
Although previous studies on customer satisfaction and loyalty are quite extensive, few have focused on customer value in LINE mobile services (LMSs) and its effect on customers, and the belief transmission mechanism of customer value has been ignored or underestimated. This study used grounded theory to summarize the evidentiary bases and concepts for establishing a conceptual model for an und...
Abstract High-voltage transmission lines are long and may cross areas without mobile networks. The tower is equipped with monitoring equipment. information of the located in non-mobile network area difficult to return. What topology used for an important engineering problem. When number towers passing through a large, traditional design method based on engineer experience cannot be applied. Aim...

Leaky dominant mode propagation regimes of a conductor-backed coplanar strip line are rigorously analyzed using the concept of critical or equilibrium points from catastrophe and bifurcation theories, in conjunction with a full-wave integral equation solution. The existence of nondegenerate or Morse critical points (MCP’s) and degenerate or fold (turning) critical points (FP’s) in coupling and ...
The paper compares different channel models used for modeling Broadband Power-Line Communication (BPLC) system. The models compared are Zimmermann and Dostert, Philipps, Anatory et al and Anatory et al generalized Transmission Line (TL) model. The validity of each model was compared in time domain with ATP-EMTP software which uses transmission line approach. It is found that for a power-line ne...
در زندگی امروزی مصرف انرژی الکتریکی به دلیل سهولت انتقال، تولید در میزان گسترده و سهولت تبدیل آن به سایر اشکال انرژی پر رونق تر گردیده است و هم چنین در سالهای اخیر مقدار توانی که بایستی از مکانهای تولید به نواحی اصلی بار انتقال داده شود رشد کاملاً محسوسی را نشان می دهد. به دلیل هزینه های سنگین تجهیزات تولید، انتقال و توزیع و همچنین نیاز به سیستم های برق رسانی مطمین، طرح های بهینه برای قسمتهای مخ...
