Abstract: Recently Broadband over power lines (BPL) has received much attention in communication technology and this is due to economically of sending high data rate services by re-use of power line cables. As data transfer via power lines to final consumer is one of the growing technologies, this study discusses the modeling and optimization of data transfer via power transfer lines and feasibility and adaptation of using this technology in Gilan are investigated. Finally, a model is evaluated for power lines by selection of a cable in selected area (Gilan province) as high speed transfer media and by investigation of the effect of different loads on channel feature, simulation and transfer function between various areas of network are considered. Simulation is done by ABCD transfer matrix and channel frequency response is achieved. This model is useful in description of frequency response of lines of this network and application in design of data transfer system.

Abstract: Through of the concept of curvature energy, and the curvature theory on homogeneous spaces is designed and constructed an electronic sensor prototype to measure curvature in 2, and 3-dimensional spaces using the programming of shape operators in micro-controllers and the value of their energy integrals along the curves and geodesics in their principal directions. The curvature obtained under the sensor device is their spectral curvature given in voltage in 2- and 3-dimensions and their perception of curvature through electronic signals on a curved surface is the curvature energy that is detected in the displacement of an accelerometer on the curved surface.
