Analytically the nonlinear partial differential equations describing the present problem are solved using Multi−step differential transform method (MDTM) one of the most successful approaches for calculating an approximate solution to a system's nonlinear differential equations [1]. Numerically paired linearized differential (momentum and energy) equations are transformed into a linear system of algebraic equations using the finite difference method (FDM). Graphs and tables are used to display the effects of different parameters on velocity and temperature. The comparisons between current results and available previous results are listed in the tables, which indicate that the current answers are very similar to the past answers. The study found that (MDTM) and (FDM) are powerful approaches for solving non-linear differential equations such as this problem.","PeriodicalId":360790,"journal":{"name":"International Journal of Advanced Engineering and Business Sciences","volume":"62 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115246946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These systems have stability issues, particularly at severe faulty conditions. This paper focuses on the fault ride-through of a doubly fed induction generator (DFIG) driven by a wind turbine using Adaptive Neuro-Fuzzy Inference System (ANFIS). The measured voltages and currents at the generator's terminals are used by the proposed ANFIS technique to identify the faulty conditions. ANFIS technology activates the wind turbine's modifying the wind turbine's aerodynamic torque. Additionally, the ANFIS controller turns on the crowbar resistance to protect the system's electrical components, particularly the power electronics converters and DC bus voltage. This paper compares the behavior of the DFIG under faulty conditions with and without the application of the suggested ANFIS approach. Using the Matlab TM /Simulink environment, the system is modeled and simulated. The results are then recorded and analyzed.","PeriodicalId":360790,"journal":{"name":"International Journal of Advanced Engineering and Business Sciences","volume":"85 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-08-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127686868","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Regarding that, unequal water distribution, misuse of water resources, and inefficient irrigation techniques were playing a destructive role in water security. Egypt also faces a water deficit of 20 billion cubic meters per year. The United Nations has warned of the running out of water in Egypt by 2025. Thus, a survival strategy is required for preserving and developing water resources. This study applies business intelligence techniques to aid decision-makers in determining the amount of water needed based on crop type, appropriate irrigation system, land size, region, planting season, and development of various scenarios for the application of modern irrigation systems. The study focuses on determining the cost of modern irrigation system implementation scenarios and the best scenario for implementing various irrigation systems, as well as their cost. The findings tool aids to improve decision-making by enabling the transformation of raw data into useful information, providing good visualization of data, and identifying trends. The developed BI tool is supporting strategic water resources management and helps in guiding the experts to determine the best scenario in applying modern irrigation systems in Egypt.","PeriodicalId":360790,"journal":{"name":"International Journal of Advanced Engineering and Business Sciences","volume":"52 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126600128","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Some see these effects as negative and others see them as positive, but the real effects appear on the short run and become clear on the long run, the positive effects appear only through the development of a long-run program. The state must adopt this program to increase exports of high value. Courageous policies are required for this decision to succeed and for the state to reach what it aspires to, so in in this paper, the authors attempts to shed light on the important effects of floating the Egyptian pound, by studying the effects of pricing the national currency before and after the flotation, to find out whether this flotation has negative or positive impact on the economic growth of the Egyptian state. Real Exchange Behavior and Evidence from Egypt, Jordan, Morocco, and Tunisia i , it examines the effect of the real exchange rate misalignment (RERMIS) on the economic growth Morocco, and Tunisia. The paper constructs three measures of exchange rate based on purchasing power parity; a black market exchange rate; and a structured model.

The results also highlighted the role of other relationship between rate and The paper uses a structural vector auto-regression (SVAR) model, drawing on Bernanke (1986) and Sims (1986), to empirically examine and analyze the pass-through of exchange rate fluctuations to domestic prices in Egypt.","PeriodicalId":360790,"journal":{"name":"International Journal of Advanced Engineering and Business Sciences","volume":"103 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114198564","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different interactive relationships between the main elements for sustainable development and the actual situation of the different cities were taken into consideration at this study. The main objective of sustainable development is, how to meet and achieve the required standard specifications of eco –cities in urban planning. A case study was conducted for two cities, the first one was Masdar city in Abu-Dhabi, Emirates and the second was Gangneung city in South Korea. This study discusses the methodology of turning the existing cities to green cities by applying the main requirements and standards of the green cities. These requirements are based on physical, economical, social and environmental aspects. Turning the existing cities into green cities may be achieved by maintaining and developing the available natural limits and resources. Economical studies are based on different factors such as, standard of living and land values. Social studies included the size of community, rates of unemployment and illiteracy. The environmental studies included water resources, renewable energies and natural topography of the concerned cities.","PeriodicalId":360790,"journal":{"name":"International Journal of Advanced Engineering and Business Sciences","volume":"16 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-02-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114749396","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
