In the opening study of Advances in Engineering Research. Volume 34, five probability distributions which are currently used by researchers, including Normal, Log-Normal II, Gumbel, Pearson type III and Log-Pearson type III, are fitted to the values of ET0 and precipitation related to 30 synoptic stations of Iran with different climates. The authors discuss an energy efficient envelope tracking solution in a power amplifier system for demanding wireless standards. In a wireless transmitter, a huge portion of power is consumed by the power amplifier, and this generates the need for a power-efficient amplifier for longer battery run-time. The authors discuss the ways that may change the way air traffic controllers and others learn and work in air navigation, as well as how they can improve their workload thanks to the implementation of holographic radars. The various methods for the detection of accidental island formation are discussed, as well as the differences between the detection methodologies. Some of the main anti-islanding algorithms are evaluated by means of a Mat Lab/Simulink(R) platform employing a single-phase voltage source inverter designed for active power injection into the low-voltage distribution network, using solar photovoltaic as an energy source. The authors survey cryptographic keys management issues related to cloud computing deployment. This provides a critical analysis of cryptographic keys management in the cloud, and explores the most valuable solutions and recommendations used in real-world applications. This compilation also explores the design, preparation, testing and applications of thin-film thermocouples, particularly the tungsten-rhenium thin-film thermocouples proposed by Xi’an Jiaotong University. Later, the best probability distribution function is combined with a suitable plotting position formula in estimating the annual reference evapotranspiration. For this purpose, using meteorological data reported in 30 synoptic stations (1960-2014), the values of reference evapotranspiration were calculated by the FAO56 Penman-Monteith method based on reference conditions. The penultimate chapter studies how to realize double station navigation under the condition that we only know the path difference and the length of baseline between two stations. A one-dimensional equidistant double-base array is directly constructed, and the azimuth angle of the target is solved using the redundant calculation. The final study proposes a technique called "Data as a Service using Data Hibernation and Service Oriented Architecture" that plays a key role in the improvement of the cloud network by enforcing a pay-as-you-go concept.
