For an assessment of the power quality in power distribution systems, classical Fourier series-based power quality indices are normally employed. The classical Fourier series-based power quality indices assume the periodicity of the disturbance so that the applications are limited to the harmonics. Hence, it is necessary for us to redefine power quality indices for the “transient” disturbances....

Because the boiler is developed to the trend of large size, high temperature and high pressure, so the requirement of water quality for the boiler makeup water is higher and higher, and that needs to almost get rid of all salts in the water. So anion-cation exchange technology has been developed quickly. For example, use the H cation exchanger to exchange various cations in the water and give o...

Power-line communications (PLC) are employed in home networking as an easy way to provide highthroughput connectivity. IEEE 1901 [3] is the dominant MAC protocol for power-line networks, and its most popular implementation is HomePlug AV. This technical report introduces guidelines for measurements in HomePlug AV testbeds. We describe two tools that manage and configure PLC devices. These tools...

The question we investigate is how to obtain PLC applications with confidence in their proper functioning. Especially, we are interested in the contribution that formal methods can provide for their development. Our maxim is that the place of a particular formal method in the total picture of system development should be made very clear. Developers and customers ought to understand very well wh...

The present study examined email communication practices of two groups of students in Iran and the United States to uncover the probable differences between Iranian and American email communication norms. The study also aimed at investigating how power distance in academic centers influences students’ choices of communication strategies in email writing. The use of two politeness strategies nam...

Smart Grids are composed of many features and new technologies which gradually incorporated to traditional electrical networks. Metering is one these features, it remotely manages consumers, enables fraud prevention, identifies faults shutdowns, distribution transformers, among others. In this context, paper presents the development a complete System utilizes Power Line Communication (PLC) tech...

Power Line Communication (PLC) technologies are being used in many applications and offer the advantage of utilizing existing power cables for both data transmission, thus minimizing cost complexity. Nevertheless, PLC technology requires further investigation to solve possible co-existence issues. Indeed, recent studies confirmed that alternative modulation schemes such as Random Pulse Width Mo...
