In addition, the shading system geometry controls both appearance and performance of the building. On the other hand, Christopher alexander -theorist and architect- developed a theory about the impact of certain geometrical rules on the human beings psychological needs. Alexander found that these rules have a great impact in removing anxiety and creating a comfortable feeling to the building occupants. Therefore, this paper investigates the following points: first, the external shading, second , the alexandrine rules and theory and third the relationship between alexandrine geometric rules and building sustainability .The investigation is done by analyzing 30 case studies which certified sustainable. The analysis resulted that there is a certain relation between using each of the fifteen alexandrine rule and achieving sustainability of the building.https://pserj.journals.ekb.eg/article_98810_134d25858020dd0306bdc43fb3ad671b.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Smart Breathing Wall for Integrated Ventilation: Heat Exchange and Indoor Air Quality Improvement10179878210.21608/pserj.2020.25973.1038ENGhadaShalabyArchitect at CHP CompanyOsamaM.

One such idea is to use the Breathing Walls "BW" built on porous materials. The energy used in air-conditioned buildings is reduced by these materials. BW suggests a conceptual design suitable for hot climates and capable of controlling airflow across the entire surface and refrigerating internal spaces in various cooling ways. BW forming all or part of an air-permeable building envelope or exterior provides a comprehensive solution to that and severe issue of self-inflicted environmental harm that many cities now face. BW are the walls that have pores inside them and are capable of spreading water vapor and helping to get rid of moisture and raise indoor air quality (IAQ). In both a social and economic context, IAQ is a significant issue. The definition of breathing walls, their characteristics, and the environmental problems that the BW solve will be discussed in this paper, as well as their impact on the improvement of the indoor air quality.https://pserj.journals.ekb.eg/article_98782_f35a20e11d77f517841a1a5d0c08a42a.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Spontaneous Areas in Egypt and the Concept of Self-Sufficiency183011007310.21608/pserj.2020.25511.1037ENHager M.ElkhodaryArchitectural Engineering and

The trend of self-sufficiency in development contributes to the effectiveness of those areas, in not completely relying on the state only and contributing to a comprehensive renaissance, and facing some of urban challenges by their residents with the help of specialists and those interested. Since these regions possess many characteristics of self-sufficiency ,such as, collective living , proximity and they are spontaneous, self-constructed communities by their residents to solve their problems and this was a reason to think about the possibility of applying the idea of self-sufficiency to developing them. Therefore, we in this paper aims to clarify the idea of self-sufficiency and its importance, and an experiment for its application to extract some criteria by which it is possible to start a strategy to guide the growth of spontaneous communities in Egypt with the concept of self- sufficiency.https://pserj.journals.ekb.eg/article_110073_8080ebba4beb984ba324ddddd9659fb2.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Stability Analysis of Geotextile Reinforced Marine Causeways31397574510.21608/pserj.2020.23793.1031ENHebaKouraCivil Engineer at Suez Canal AuthorityEhabTolbaCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, EgyptElsayedGalalCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, EgyptJournal Article20200210The use of geotextile tubes as retaining systems, geotechnical application, and coastal protection in temporary and permanent structures is gaining lots of concern throughout the recent decades. In the present study, computer software, ABAQUS, was used to investigate the stability of geotubes as soil retaining structure for marine causeway. Nine scenarios comprised of two geotubes lining the side of a 1:1 slope causeway were modeled to explore their effect on the causeway displacement under surcharge loads. The stability of the system was investigated through using different deformed shapes of geotubes. These deformed shapes were obtained by using different pumping pressures (0.0, 5.0, and 20.0 kPa). Moreover, the effect of tidal range was studied by defining different water depths (0.5, 1.5 and 2.5 m measured from the causeway toe). The results showed that the use of geoextile tubes subjected to pumping pressure of 0.0 and 5.0 kPa improves the deformation behavior of the causeway with water depths of 0.5 and 1.5 m. While, the deformation was aggravated with water depth of 2.5 m when using geotextile tubes subjected to pumping pressures of 0.0 , 5.0 , and 20.0 kPa. On the other hand, the model ceased when applying pumping pressure of 20.0 kPa with water depths of 0.50 and 1.50 m due to the failure of the upper tube. Therefore, it is recommended to use the geotextile tubes subjected to pumping pressure of 0.0 and 5.0 kPa in case of lower water depths only.https://pserj.journals.ekb.eg/article_75745_b4650893790e48c88c596b1b0f291597.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901A Roadmap for Establishment of an Early Warning System for Nile Water Quality in Egypt405110295910.21608/pserj.2020.18756.1014ENMohamed E.GabrCivil Engineering Department, Higher Institute for Engineering and Technology, New Damietta, Ministry of Higher Education, Egypt0000-0003-2448-601XJournal Article20191027The Nile River is the lifeblood of Egypt. The necessity to rationalize Nile’s water uses and protecting from pollution and accidents in Egypt is an urgent issue. Continuous monitoring and utilizing the early warning system (EWS) were becoming important tools to protect and manage water sources for sustainable development. The aim of this study is to design and propose guidelines for the establishment of an (EWS) in real-time to ensure the safety of Nile water in Egypt and to mitigate the water pollution disaster by terrorism and accidents. To achieve this objective, (1) it is reviewed the EWS basic structure regarding risk knowledge, monitoring system, active communication of information and the plans for readiness and response (case study the Rhin river), (2) it is assessed the current water quality monitoring in the Nile and the current problems regarding the implementation of the early warning system for Nile water quality, (3) it is examined the characteristics of a Nile EWS, and (4) it is recommended a roadmap for establishing the proposed EWS. The roadmap for EWS describes a process in four steps, a start-up by a letter of interest from all ministers, organizational setup, implementation and testing, and continuous improvement. A steering committee consisting of the main ministries recruited from the National Council for the protection of the Nile that determines responsibilities, and that can take corrective actions to optimize the EWS. The proposed EWS will provide a sufficient information database for the decision-makers in sustainable water management.https://pserj.journals.ekb.eg/article_102959_8a1bb2dd01318144427622185086cc58.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901A Hydrodynamic Study of Water Flushing Parameters to Improve the Water Quality Inside Marinas and Lagoons52627581610.21608/pserj.2020.23849.1032ENElsayedGalalDepartment of Civil Engineering, Faculty of Engineering, Port Said University0000-0002-1079-1868AhmedLeblebCoastal and Marine Engineer at Dar Al-HandasahEhabTolbaProfessor, Faculty of Engineering, Port Said University, Egypt,Journal Article20200212This research describes how integration of engineering and environmental aspects into the planning with extensive use of numerical hydrodynamics models by using MIKE 21 software. A parametric study for different parameters which affect the residence time hence the water quality in lagoons, marinas, harbors and coastal basins was carried out to establish guidelines to improvement methods for water flushing of marinas and lagoons. Finite element conceptual computer models are applied to simulate and investigate the most important factors dominate the resident time and water exchange rate like tidal inlets characteristics (number-location-width), the shape of water body, basin dimensions and tidal variations. The boundary condition, water level variations used in simulations are collected based on the conditions of fishery ports and lagoons along Egyptian coastal line in Mediterranean and red sea. This study conducted a wide range of numerical simulation (more than 50 HD models) with different geometry and boundary conditions. The results showed that the square shape of water surface area is more efficient for small water body areas. While, as the area required increased, the rectangular water surface efficiency become closer. The inlet width and its location should be determined wisely to achieve the optimization for the usage of project. Finally, the results showed that as the level variations values increased, the maximum flood current velocities at the entrance increased. In addition, the flow spreading quality increased with higher water level values over the all water surface area regardless the water depth.https://pserj.journals.ekb.eg/article_75816_f3aaf96564a1d895f5c28f46e7b43d95.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Effect of Cementitious Materials Composition on Heat Evolution and Strength of Concrete63769980210.21608/pserj.2020.26323.1039ENMohammed H.BelalCivil Engineering Department, Faculty of Engineering, DamiettaShady R.RaghebDepartment of Civil Engineering,Faculty of Engineering, Port Said UniversityHassan M.HassanCivil Engineering Department, Faculty of Engineering, Port SaidJournal Article20200321Large and massive concrete structures with high cementitious content like foundations, tunnels, bridges, dams and hydraulic structures are subjected to cracks generated and developed by internal thermal stresses and damages due to delayed ettringite formation (DEF) associated with the hydration process of cement. The Ondes bridge, Bourgogne bridge and Saint-Maurice de Beynost bridge are international examples of concrete structures damaged by delayed ettringite formation (DEF). Due to the construction expansion in Egypt and the middle east, it was necessary to study the effect of concrete constituents on the evolution of concrete heat of hydration and the differential temperature between the core and the concrete surface, as well as the mechanical properties such as the compressive strength. In this study, the effects of six types of cement, two water-binder ratios, with two different cement contents and supplementary cementitious materials like silica fume, fly ash and metakaolin were studied. The test results of hardened concrete showed that the blast-furnace cement and moderate heat of hydration cement had an obvious effect on the hydration heat rate and concrete compressive strength compared to other tested types. Partial replacement of cement by 50 % fly ash led to a decrease in maximum hydration temperature nearly by 13-14%. Replacement of cement by 15 % metakaolin led to an increase in maximum temperature by 2.9 % comparing to reference cement. A best thermal gradient of mass concrete was observed in case of using moderate heat of hydration cement, as the maximum temperature difference was 17.5℃.https://pserj.journals.ekb.eg/article_99802_17b7e85884fc7eab2d1e844b92c9a8ae.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Detection of Seismic Movements Using GNSS Data778510933610.21608/pserj.2020.35662.1051ENRashaMosadCivil engineering.

Such disasters lead to changes in the Earth's crust and hence movements of some points. Therefore, studying these movements has great benefits, such as the ability to predict the occurrence of an earthquake, which helps to control and minimize human and economic damages. It is possible to evaluate accurately the magnitude of point displacements and to find the factors affecting these displacements. In this research work, we explain the seismic monitoring techniques using the global navigation satellite system (GNSS), which considered a powerful tool for monitoring the ground points displacements, Bernese GNSS Software 5.2[4], was used to obtain high-precision of the results of the IGS stations data and their displacements, with the application on the network stations in the study area of Turkey,(Aegean sea earthquake).https://pserj.journals.ekb.eg/article_109336_789ec4f417dfec497ba95e26835bfc4e.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Parametric Study on Steel Girders with Corrugated Webs86968346210.21608/pserj.2020.17735.1010ENMuhammadShukrySenior Engineer, Zagazig University Consulting OfficeTarekSharafAssociate Professor, Faculty of Engineering, Civil Engineering Department, Port Said UniversityAshrafElsabbaghCivil Engineering Department,Faculty of Engineering, Port Said UniversityMohamedElghandourFaculty of Engineering, Civil Engineering Department, Port Said UniversityJournal Article20191003I-shaped Steel Girder with Corrugated Webs [SGCW] are used in steel structures because of their notable advantages. SGCW permit using a thin web plate without using stiffeners. This girder is useful for eliminating the use of stiffeners and larger thickness that contribute to the reduction in the weight and the cost of the girder. In this paper, a numerical study based on the Finite Element Analysis [FEA] was conducted to predict the behavior of SGCW. The verification study was conducted for previous experimental tests. Based on the previous investigations, the parametric study was carried on to investigate the actual behavior of SGCW with different parameters such as the web thickness, the girder height, the web shapes, and the corrugated angles under different loads. The results of the parametric study showed the effect of each parameter on the overall load carrying capacity of the beams and indicated that the corrugated angle is the most effective parameters for SGCWhttps://pserj.journals.ekb.eg/article_83462_8b7d0feba3423d9edfa1ab72821ebc7a.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Design and Economics of a PV-based Pumped Hydro Storage Station in Rural Distant Areas in Egypt9710511009910.21608/pserj.2020.32005.1042ENHilmyAwadAssistant Professor, Faculty of Technology and Education, Helwan UniversityNadiaShoukryTeacher, Ministry of Education, Cairo, EgyptAhmadAtallaProfessor, Ain Shams UniversityHassanMostafaVice Minister, Electricity Authority, Cairo, EgyptJournal Article20200616Although photovoltaic (PV) Energy is a viable solution and clean energy source, it is an intermittent source and certainly needs energy storage, particularly in the case of off-grid applications. Batteries are normally used as the common energy storage, despite all their demerits. <br />This paper presents a preliminary design and cost estimate of a potential candidate for energy storage applications, which is the PV-based Pumped-Hydro Energy Storage (PHES). The proposal is suited for application in rural and distant areas, where the public electric grid is not easily accessible. <br />The basic idea is that the required load demand is fulfilled by PV panels during the day. During the periods of high insolation, the PV panels are also used to pump water to a 31-m height tank. Then, at night or in periods of low insolation the water is allowed to flow downwards operating a hydro generator. <br />Based on the average expected load (irrigation and domestic) of distant locations in Egypt, the PV panels and reversible pumps have been sized together with other system components. A cost estimate has been done to compare batteries and PHES for the average lifetime of the two systems. <br />The cost estimate revealed that the PHES would be economically viable after 23 years of service. The system can be easy to extend to a larger scale by adding more reversible pumps and PV panels.https://pserj.journals.ekb.eg/article_110099_98107d4139e585e28d839e685beaf3f4.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Experimental Investigation of Generated Surface Roughness in Hard Turning of Ti6Al4V Using Coated Ceramic and CBN Inserts10611310077810.21608/pserj.2020.32857.1045ENAl ShimaaAbdelnasserlecturer assistant at faculty of engineering, port said universityAzzaBarakatProduction Engineering Dept., Helwan University, Cairo, EgyptSamarElsanabaryDepartment of productionengineering and mechanical design, Faculty of Engineering, Port Said University, Port Said, Egypt0000-0001-9829-3814AhmedNassefDepartment of Production and Mechanical Design Engineering, Faculty of Engineering, Port-Said University, Port-Fouad, Port-Said 42523, EgyptJournal Article20200620Surface finish of machined parts is a significant quality mark for a range of application such as aerospace, automotive, power transmission and generation. Therefore, optimization of surface roughness is the key factor for reliability in machining difficult-to-cut materials such as titanium-based alloys. In this study, investigation into hard turning of Ti6Al4V alloys with varying process parameters and cutting tool materials was carried out. This paper aimed to compare the generated surface roughness when turning Ti6Al4V alloys using CBN and coated ceramic inserts, independently, under different feed rate, cutting speed and depth of cut. The experiments trials were designed using Taguchi L9 and the exponential results are examined results by the analysis of variance (ANOVA). The effect of process parameters and their interactions on generated surface roughness was evaluated for the two inserts. It was found improvement in surface roughness by 34% was achieved when using coated ceramic insert compared with the results obtained using CBN insert under the same cutting conditions. CBN insert gave a better result at smallest depth of cut (0.15 mm), low feed rate (0.1 mm/rev) and high cutting speed (100 m/min) while coated ceramic tool gave a minimum surface roughness at depth of cut (0.2 mm), feed rate (0.1 mm/rev) and high cutting speed (100 m/min).https://pserj.journals.ekb.eg/article_100778_28c6abe68ba556d940eeaa1efe0f07f6.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Relative Performance of Coated Ceramic and CBN Inserts in Hard Turning of Ti6Al4V Alloy11412110077710.21608/pserj.2020.32842.1044ENAl ShimaaAbdelnasserlecturer assistant at faculty of engineering, port said universityAzzaBarakatProduction Engineering Dept., Helwan University, Cairo, EgyptSamarElsanabaryMechanical Production Dept., Faculty of Engineering, Port Said University, EgyptAhmedNassefDepartment of Production and Mechanical Design Engineering, Faculty of Engineering, Port-Said University, Port-Fouad, Port-Said 42523, EgyptJournal Article20200618Characteristics of cutting insert are key factors for the reliability of machining of difficult-to-cut materials such as Ti6Al4V alloy. Therefore, in this paper a comparison between the performance of two different materials, ceramic insert coated by (Al2O3+TiNC) and CBN, when turning Ti6Al4V alloy in dry environment. Effect of process parameters, feed rate, cutting speed and depth of cut, and their interactions on measured cutting temperature were examined for both inserts. Taguchi method was utilized to design of experiments (L9) and the results were analyzed by analysis of variance (ANOVA). From the results, CBN insert showed a good behavior for heat dissipation during machining compared with coated ceramic insert with a reduction in cutting temperature by 28%. Moreover, it was found that cutting temperature increased by increase in cutting speed and depth of cut and decrease in feed rate when using the two types of insert. In addition, it was observed that cutting temperature was affected by varying process parameters when machining by CBN insert more than the case of coated ceramic tool. The significant parameter affected cutting temperature in the case of CBN was feed rate followed by cutting speed.

It has the advantage of high power to weight ratio, linear movement and fast response. In order to overcome the problem of nonlinearity of the controlled system, a sliding mode controller, ESMC, is proposed in such a way that the error signals modifies the ordinary switching mode control action. Pulse width modulation, PWM, technique is used to convert the control action into a digital signal capable of driving the solenoid of an electrohydraulic servo valve to control the oil flow entering the hydraulic cylinder so that its position could be controlled. A dynamic model of an electrohydraulic control system is simulated using MATLAB/Simulink software where the control parameters are optimized for experimental testing of PID and sliding mode controllers. The two controllers are then fine-tuned experimentally, and their performance is compared under square and sinusoidal reference inputs. The experiments showed that the proposed ESMC gives less steady state error, less overshoot and less settling time as compared to both PID and the ordinary switching sliding mode controllers.https://pserj.journals.ekb.eg/article_96029_4bc1343878d5885dd38a6f69f1cb5f35.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660324220200901Simulation Study and Experimental Position Control of Pneumatic Cylinder Using Sliding Mode Control with on/off Control Valves1291368575710.21608/pserj.2020.22883.1030ENY.El-sayedMechanical Power Engineering, faculty of engineering,port saied university, Port saied, EgyptM.HammamMechanical Power Engineering, Faculty of engineering,Port Said University, Port Said, EgyptG.

Comparison of the performance of the closed loop position control using SMCE with the traditional PID is held. The simulation model is used to optimize the SMC and PID controller parameters to start the experimental test as a first trial. The experimental results for square and sinusoidal position reference show superiority of the SMCE over the PID in terms of lower steady state errors, faster settling time, and less overshoot. The root mean square error for a sinusoidal input of 0.1 Hz, is 0.22 mm for SMCE and 0.69 mm for PID controller. The maximum absolute errors are 0.66 mm and 1.46 mm for SMCE and PID respectively.https://pserj.journals.ekb.eg/article_85757_23d36f7c269097ab5f4f0ce0e3485dbf.pdf
