In this work we have given the values and test performance for the integrated digital loop carrier model. We have used the measures that are based on the modes that characterize both up and downstream modes and we have calculated the statistical data. The noise presented in the loops are measured and we have the statistical data. We have tested experimentally with numerical data for the noise margins of the loops during the fast mode.

Abstract In this work we have given the data to study the voltage increase rates using discrete dynamic method. This is used for studying the gas-filled surge arresters. The data that we have drawn is projecting the consistency which is shown in a perfect graph. In the intersection of the line fit we saw the breakdown of the voltage data which... In this work we have given the data to study the voltage increase rates using discrete dynamic method. This is used for studying the gas-filled surge arresters. The data that we have drawn is projecting the consistency which is shown in a perfect graph. In the intersection of the line fit we saw the breakdown of the voltage data which is presented in the datasheet available. We also noticed that the response time of the GFSA by the siemens is not depending on any parameters and the electrical breakdown values show a relaxation time. The response time shows increase with the relaxation time and it is the consequence of the positive ions concentration. During the breakdown we found the formation of neutral active particles where the response time decrease with the increase of applied voltage. We noticed that the value change depends on the relaxation time in the case of GFSA and it is not applied to the other GFSA. Read More Read Less

Abstract The sensor network that we studied the observation of the indicators in the workplace for an evaluation of work conditions. We have given the two models of measuring the temperature change. The models given for other conditions of the workplace are used in the studied sensor networks....
