Studies have shown that urban spaces that do not satisfy user requirements lead to negative impacts (environmental / behavioral / social / cultural / ...) on these individuals; This will lead to abandonment of these urban spaces or trying to make adjustments to suit their needs, or acquire new behaviors that help them to cope with these spaces.<br /> The research paper provides an explanation of the urban spaces research topic (definition and objectives) and design determinants. The research explains the nature of open markets as one of the most important urban spaces that are dealt with on a daily basis, and the characteristics of urban and design foundations and types with a presentation of some experiences from different countries for projects to develop markets, with a view to improving and upgrading and the impact of this development on human behavior.<br /> The paper discusses the issue of the spread of open markets which are part of the urban spaces that affect human behavior. In fact, the existence of activities in the inappropriate spaces leads to an imbalance in the surrounding urban environment. The research presents a case study of the open markets in Minya and offers solutions to upgrade them after analyzing them and benefiting from previous experiences.<br /> The research concludes with a set of general findings and recommendations through which we can draw some realistic solutions to the problems of open markets in order to work to improve human behavior.https://jaet.journals.ekb.eg/article_76392_cfe6e51c9021c3faaa582f4d61c613a1.pdfMinia University, Faculty of EngineeringJournal of Advanced Engineering Trends2682-209139220200310EVALUATING OF THE ECONOMIC HOUSING PROJECTS IN THE EGYPTIAN CITIES BASED ON THE POPULATION REQUIREMENTS (MINIA NEW CITY AS A CASE STUDY)19487666710.21608/jaet.2020.76667ENAshrafAbu El-Ayoun Abdel-RahimDepartment of Architecture, Faculty of Engineering, Minia University, EgyptOsamaHelmy HaddadDepartment of Architecture, Faculty of Engineering, Minia University, EgyptOmniaNagy Abd El-HafeizDepartment of Architecture, Faculty of Fine Arts, Minia University, EgyptJournal Article20191110Housing is not just walls and engineering designs, but is an integrated life of housing, work, services, activities and integrated urban environment, The concept of housing in many countries has become much more comprehensive than the simple considerations that can be defined the same housing as the definition extended to include the possibility of achieving housing for economic, social and urban needs including the location and basic services, transport and public facilities. Some have identified the housing problem in general as a study of housing market problems in which the people can get adequate house meets their economic, social and urban requirements. So housing is an interconnected system with many elements and depends on its application to a range of sciences such as urbanization, sociology, economics, architecture, interior design and politics, and sometimes it seems necessary to know all these systems and aspects to solve one of housing problems. It has been found that the housing policies adopted in some countries, including Egypt, do not cover some or all of these aspects, resulting in the emergence of many housing problems in each of them, especially in the field of affordable housing projects.

A simple electrochemical cell was performed with horizontal mild steel iron disc anode and vertical stainless steel cylindrical cathodes (screen or sheet). Process duration, agitation speed, current density, initial dye concentration and electrolyte NaCl concentrations were the variables studied. It was found that screen cathode was more effective than sheet cathode. . For dye solution with 50 ppm and agitation speed 100 rpm after 18 min, 86 % color removal was achieved on using screen cathode, while 77 % color removal was achieved on using sheet cathode. The higher efficiency of screen cathode is attributed to the fact that screen acts as turbulence promoter and generate high turbulence intensity.https://jaet.journals.ekb.eg/article_76894_59f54d5977f56c4de688b95e72d9ed24.pdfMinia University, Faculty of EngineeringJournal of Advanced Engineering Trends2682-209139220200316ABOUT THE EGYPTIAN NATURAL GAS; AN OVERVIEW, HISTORY AND PROSPECTS1091177745410.21608/jaet.2020.77454ENN.SAbbasProcess Section head, (GUPCO), Cairo, Egypt.H.MAssfourCorrespondence person, at the address of prof.

It is mainly used to avoid failure that may be accompanied by considerable settlements, tilting or by bearing capacity failure of nearby foundations. The cost of these systems mainly depended on soil type and excavation depth. In this research, strutted shoring systems are analyzed and designed for sandy soil conditions and excavation depth 15m. The system is optimized using Genetic Algorithm. Finite Element Method is used for the analysis. The designed problem is formulated as a non-linear mathematical programming problem using FORTRAN 95. The developed model is used for parametric study to investigate the influence of different design parameters on the system cost. Genetic Algorithm, is used to perform the optimization study based on the minimum cost. The optimization process aims to minimize the system cost considering both deformation and stress constraints for the ground soil and construction material.https://jaet.journals.ekb.eg/article_77730_5d4dd145e9c296f5d83bcfe58c41290d.pdfMinia University, Faculty of EngineeringJournal of Advanced Engineering Trends2682-209139220200718BEHAVIOR OF STEEL HOLLOW SECTIONS UNDER BLAST LOAD1211349645010.21608/jaet.2020.96450ENAsmaa A.FekryCivil Eng.

Thus, strengthening of steel hollow tubular members is required to safely carry the dynamic loads to increase the security demands when the accidents, intentional impact, or explosive events occurred. In this paper, a finite element analysis tool, LS-DYNA is utilized to study the behaviors of (SHS) beam under a uniform transverse blast load. The explosive loads were sufficient in magnitude to cause plastic deformation of the cross-section (local deformation) and plastic flexural deformation of the overall member (global deformation). Different parameters were studied to investigate the effects of beam depth (H), beam width (B), support condition and axial load on the failure mode. The obtained displacement-time history from each simulation was recorded and compared. A numerical method for deriving pressure–impulse (P–I) diagrams for (SHS) beam, which subjected to transient loads are described in this paper, which can be applied in the preliminary design of protective structures to establish safe response limits based on the given blast-loading. The proposed model of (P–I) diagrams exhibited a good accuracy in predicting the pressure–impulse diagram to design the (SHS) beam under the extreme loads.https://jaet.journals.ekb.eg/article_96450_ffe0c30fbf0021250492185cf924edda.pdfMinia University, Faculty of EngineeringJournal of Advanced Engineering Trends2682-209139220200718IMPROVIMG THE DLC (DISTRIBUTION LINE CARRIER) SYSTEM BEHAVIOR THROUGH MEIUM VOLTAGE NETWORKS (MVNs)1351449645110.21608/jaet.2020.96451ENKamelRahoumaFaculty of Engineering

There are generally no communication cables in the MVNs' equipment such as the MV transformer and distribution stations. One of the costless technologies used to communicate between the MVNs' equipment and the control center of a SCADA system is the DLC communication technology, where, data transfer occurs directly on the medium voltage cables, i.e. on the conductors of the underground and/or the overhead cables or on the shields of the underground cables. However, the DLC system suffers from many problems concerned in MVNs. In addition, the design of the DLC system itself has some defects, which affect its performance and stability. Here, we explain with simulation the exits instability margins of the operation of the DLC system to help us how we can improve the stability margins of the system to achieve a good performanceMinia University, Faculty of EngineeringJournal of Advanced Engineering Trends2682-209139220200718SCADA-BASED METHODOLOGY FOR CIRCUIT BREAKER MONITORING AND PROTECTION IN ELECTRICAL DISTRIBUTION NETWORKS1471559645310.21608/jaet.2020.96453ENGamal M.DousokyElectrical Engineering Department, Faculty of Engineering, Minia University, Minia, Egypt.0000-0002-4737-4259Osama K.

The major goal of SCADA is collecting real-time data, controlling equipment and monitoring processes in critical infrastructures and most SCADA systems achieve these functions. Furthermore, in this research the benefit of SCADA system is maximized by other additive functions such as predicting the protection and maintenance procedures of the electrical network components. The circuit breaker is the most important component in the network which must be kept safe and its operation should be carefully monitored. In this paper, the problem of explosion of the expansion chambers in the circuit breaker is discussed and two solutions are suggested to handle this problem by using SCADA system. This research investigates a real existing system and the results of the study is used to enhance the maintenance and operation by monitoring the state of the circuit breaker. The possibility of leakage that may occurs during faults in SF<sub>6</sub> gas is estimated for remaining its life time. Accordingly, the cost burdens due to fault occurrence will decrease by activating the predictive maintenance.https://jaet.journals.ekb.eg/article_96453_d4a93cab83f2323908464c14f923d100.pdfMinia University, Faculty of EngineeringJournal of Advanced Engineering Trends2682-209139220200718AN EXPERIMENTAL EVALUATION OF PHOTOMETRIC PERFORMANCE AND POWER QUALITY OF LED LAMPS IN DIFFERENT OPERATING CONDITIONS1571669645410.21608/jaet.2020.96454ENGamal M.DousokyElectrical Engineering Department, Faculty of Engineering, Minia University, Minia, Egypt.0000-0002-4737-4259Zeyad M.

This paper presents a CMOS power amplifier (PA) for Ultra-Wideband (UWB) applications in 2.2 to 5 GHz using two stages of common source topology with derivative superposition (DS) method. Simulation results show an average power gain of27.2 dB with an input 1dB compression point (1dB-CP) of -14.6 dBm at 3.2 GHz and an output 1dB compression point (1dB-CP) 12.9 dBm. With an input power of 83.8 mW, from a 1.8 V supply, power added efficiency (PAE) is 47.5% at 3.2 GHz with 50Ω load impedance and stability factor is 7.2 at 3.2GHz. The proposed design has been simulated using TSMC 0.18µm technology. The important parameters that define an RF Power Amplifier are: Output Power, Gain, Linearity, Stability, DC supply voltage, Efficiency, Ruggedness.
