“…Based on the comprehensive correlation analysis of independent variables, a remote sensing image monitoring model for vegetation destruction in waterfront greenway is established (Deymi-Dashtebayaz and Kazemiani-Najafabad 2019). The remote sensing image monitoring model for vegetation destruction in waterfront greenway includes seven multiple linear regression models, as shown in Table 10.…”

<p>Because the traditional remote sensing image monitoring method has the problem of poor ability of capturing vegetation destruction, an ecological remote sensing image method for vegetation destruction in waterfront greenway based on genetic algorithm is proposed. The vegetation index data of waterfront greenway were acquired by remote sensing image, and the pseudo color image was synthesized. The on orbit radiometric calibration and geometric precision correction are carried out for the collected data, and the relationship between vegetation index and vegetation damage of waterfront greenway is analyzed, including meteorological factors, geographical factors and vegetation damage of waterfront greenway. Select the independent variables of the model, establish the ecological remote sensing image monitoring model of the vegetation damage of the waterfront greenway, and realize the ecological remote sensing image monitoring of the vegetation damage of the waterfront greenway. The experimental results show that the acquisition ability of the method based on genetic algorithm is better than that of the traditional method, and it is more suitable for the ecological remote sensing monitoring of the vegetation damage of waterfront greenway.</p>

“…This paper focus on cooling inlet compressor air by fogging system applied on gas turbine in Egypt. [1] Mahdi Deymi-Dashtebayaz and Parisa Kazemiani-Najafabad [1] Studied the effects of some compressor inlet air cooling methods to increase the performance of Shahid Hashemi-Nezhad gas turbines located in Iran, the methods using in this study are media Pressure drop station, fogging and absorption chiller. This study uses the exergy, environmental, and economic analyses to select the best method of compressor inlet air cooling.…”

This paper investigates the effect of operating fogging cooling system on gas turbine on its performance, technical and economic study. This study was made for both 4 hours and 10 hours of operating fogger by actual data from power plant in Egypt. The technical study shows that the maximum increase in power is from 18 to 20 MW. When the ambient temperature increased from 25 to 40 C during a typical summer day, The power jumped from 220 to 238 MW after the operation of fogger. Moreover, The specific fuel consumption decreased from 0.218 to 0.214 (1.8% reduction) and the electric efficiency changed from a minimum value of 35% to 35.8 %. The economic indicators such as the net present value (NPV), Internal return rate (IRR), rate of return (ROR), and pay pack period were obtained. The economic study recommends the operation of fogger from 10 AM to 8 PM. The study showed that there is no economic justification when operating the fogger 4 hours because the net present value (NPV) is -902,716 $ for discount rate of 10% during the period of 20 year. But when operating the fogger 10 hrs. Daily in summer, the net positive value (NPV) is 4,522,493 $, Payback period=5 years, and the internal return rate (IRR) is 26 %.

“…Deymi-Dashtebayaz et al considered energy, exergy, economic and environmental points of view. The authors noted that absorption chiller, in addition to the best performance for the cooling of the inlet air, causes thermal and exergy efficiency improvement [9].Abdalisousan et al optimized some thermodynamic properties of a combined cycle power plant considering economic and exergy efficiency. They noted that using this optimization, the cost of production per unit of output goes down about 2%, and the exergy efficiency goes up by 4% [10].…”

Solar energy is one of the most promising strategies to reduce energy consumption and emissions pollutions. In this paper, integrating a combined cycle power plant with a Solar Parabolic Trough Collector (PTC) is evaluated and investigated. In this regard, Qom Combined Cycle Power Plant is considered a real case study in Qom city. Energy, Exergy, Exergoeconomic, Exergoenvironment, Emergoeconomic, and Emergoenvironemntal Analysis as (6E) Analysis have been performed to understand the base plant's integration better. Environmental impacts have been calculated by Life Cycle Assessment (LCA) in Sima Pro Software. Also, computer code has been developed for 6E analysis of base and integrated power plants. Validation of thermodynamic simulation has been examined with Thermoflex Software and plant data. Energy analysis results show the power output of the steam plant and overall energy efficiency is increased to 7.14% and 4.44% rather than the base case without adding additional fossil fuel. It shows the power generation and energy efficiency are increased significantly by adding PTC. Also, the overall exergy destruction and the total exergy cost rates are raised to 7% and 11.27%. In addition, overall environmental impacts, overall emergoeconomic, and overall emergoenvironmental values are increased to 1.67%, 6.2%, and 15.4%, respectively. However, the overall environmental impacts per net power are decreased.
