To measure the phase advance of the carrier signal using intelligent neural networks is proposed that used a new model. To achieve this task, we have developed the system based on multilayer perceptron network. In this process, to find the near value of ions concentration, we have used the latitude of the observed receiving terminal and the present point in time. The obtained data enable the measurement of the phase advance of the carrier signal. This is done with the propagation through the ionosphere. The present model design helps the measurement of ionospheric carrier phase advance and it is tested in the target areas. Read More Read Less

Abstract In this work we have designed a micro strip patch antenna with two arc shaped slots. We have used in the in house solver based TLM method. We have tested it to know the performance efficiency. The designed antenna reflects the dual frequency operation. We also found that the arc-shaped slot dimensions are easily controlled....

Abstract There are many research activities carried out to enhance the energy efficiency of the buildings. We have used the wireless sensor network to develop a low cost and low powered network to ensure energy efficiency. The proposed wireless sensor network takes the low energy Bluetooth technology for linking sensor nodes that used the simple link sensor tags. The performance tests... There are many research activities carried out to enhance the energy efficiency of the buildings. We have used the wireless sensor network to develop a low cost and low powered network to ensure energy efficiency. The proposed wireless sensor network takes the low energy Bluetooth technology for linking sensor nodes that used the simple link sensor tags. The performance tests have been carried out to estimate how the wireless network sensors can ensure the temperature in different places of the buildings. Read More Read Less
