Performance Comparison Of Several Control Algorithms For Tracking Control Of Pantograph Mechanism, Laylaa Mahmoud Eng, Mohamed Shamseldin Dr, Mohamed Sallam Dr, Abdelghany Mohamed Prof

Future Engineering Journal

A sort of parallel manipulator known as a pantograph robot mechanism was created primarily for industrial requests that required high precision and satisfied speed. While tracking a chosen trajectory profile requires a powerful controller. Because it has four active robot links and one robot passive link in place of just two links like the open chain does, it can carry more loads than the open chain robot mechanism while maintaining accuracy and stability. The calculated model for a closed chain pantograph robot mechanism presented in this paper takes into account the boundary conditions. For the purpose of simulating the dynamics …

Relative Rate Observer Self-Tuning Of Fuzzy Pid Virtual Inertia Control For An Islanded Microgrid, Ahmed H. Mohamed, Helmy M. El Zoghby, Mohiy Bahgat, A. M. Abdel Ghany

Future Engineering Journal

Expanding the usage of renewable energy in islanded microgrids leads to a reduction in its total inertia. Low inertia microgrids have difficulties in voltage and frequency control. That affected saving its stability and preventing a blackout. To improve low inertia islanded microgrids' dynamic response and save their stability, this paper presented relative rate observer self-tuning fuzzy PID (RROSTF-PID) based on virtual inertia control (VIC) for an islanded microgrid with a high renewable energy sources (RESs) contribution. RROSTF-PID based on VIC's success in showing remarkable improvement in the microgrid's dynamic response and enhancement of its stability. Moreover, it handles different contingency …

The Effective Strategies For Mitigation The Impact Of Covid-19 On Construction Projects In Egypt, Nora Magdy Essa, Ibrahim Mahdi, Hassan Mohamed Ibrahim

Future Engineering Journal

From the time when the first narrated infections in Wuhan China, in late 2019, COVID-19 has had a substantial peal on human life and health. By the early of 2020, the World Health Organization (WHO) announced the eruption of COVID-19, a public health crisis of international concern. On 11 March 2020, the World Health Organization officially announced COVID-19 a pandemic. The first case was infected in Egypt of covid-19 on Feb 14, 2020 (Gilbert et al., 2020). On 16 March 2020, the Egyptian Government began issuing decisions as preventative courses as part of the country's inclusive plan to cope with …

Estimating The Weights Of Latticed Power Transmission Towers Using Genetic Programming, Ahmed M. Ebid Dr.

Future Engineering Journal

The recent booming in the power network industry inspired a lot of researchers to develop models to estimate the optimum cost of transmission towers. Unlike previous researches which depended on design the tower from scratch, this research depends on collecting actual database from several projects around the globe and applying the well-known (GP) technique to develop a model to predict the tower weight. The accuracy of the developed formula was about 84%. The developed model could be used in early tender stage or to check design economy.

The Fundamentals And Obstacles Of Religious And Cultural Tourism Development In Hadhramout Governorate: A Case Study Of Tarim City, Abdulaziz Al-Naggar, Sabri Al-Tarimi, Fahd Jowher

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

This research discusses the fundamentals and obstacles of the religious and cultural tourism development in Hadhramout Governorate, as one of the most important types of tourism. The aim of this study was to determine the basic requirements needed by this type of tourism through studying the elements of developing the religious and cultural tourism in Tarim City. The city was chosen because of its famous palaces, castles, and historical forts. Tarim is also famous for its prominent scientific and religious center founded in the 4^th century A.H., the presence of libraries, such as the Al-Kaf Library, the religious institutes(Rabat …

Assessing The Impact Of The Campuses’ Landscape Design On The Stress Levels Of The Students Using The Salutogenic Model (The New Campus Of Al-Aqsa University As A Case Study), Ahed Helles

Journal of the Arab American University مجلة الجامعة العربية الامريكية للبحوث

Studies in the field of environmental psychology have found that there is a strong correlation between the built environment and stress on the one hand, and between stress and health on the other hand. This research used the Salutogenic theory introduced by Antonovsky to examine the impact of architectural elements and design features of the outdoor spaces within learning environments, such as those of university campuses, on the level of stress of the university students, using the new campus of Al-Aqsa University in the city of Khan Younis (in The Gaza Strip) as a case study. The hypothesis of the …

Bioclimate Of Jericho In Palestine, Jehad Ighbareyeh

Palestine Technical University Research Journal

Jericho is an ancient Canaanite Palestinian city and one of the oldest cities in history, which dates back to more than 10.000 BC (Stone Age). It is located near to the Jordan River, north of the Dead Sea, and north of Jerusalem. Moreover, it considered the lowest area in the earth and has a unique climatic zone. during the study period (1975-1995), was utilized the Salvador Rivas Martinez scale to classify the bioclimate of the earth to analysis the climate and bioclimate data, which was obtained from one station from Palestinian Meteorology Department (Jericho station). The results revealed that the …

Visible/Near Infrared (Vis/Nir) Spectroscopy And Multivariate Data Analysis (Mvda) For Identification And Quantification Of Olive Leaf Spot (Ols) Disease, Nawaf Abukhalaf, Mazen Salman

Palestine Technical University Research Journal

Early detection of plant disease requires usually elaborating methods techniques and especially when symptoms are not visible. Olive Leaf Spot (OLS) infecting upper surface of olive leaves has a long latent infection period. In this work, VIS/NIR spectroscopy was used to determine the latent infection and severity of the pathogens. Two different classification methods were used, Partial Least Squared-Discrimination Analysis (PLS-DA) (linear method) and Support Vector Machine (SVM) (non-linear). SVM-classification was able to classify severity levels 0, 1, 2, 3, 4, and 5 with classification rates of 94, 90, 73, 79, 83 and 100%, respectively The overall classification rate was …
