Mixed Mode building is a combine of natural ventilated building and AC building which needs different strategy of design which make the Mixed Mode building face a problem in design. this paper aims to reach a strategy to design mixed mode buildings envelope in greater Cairo to reach optimum energy consumption. the research concludes that the MMB is near to be a natural ventilated building with slight heavier south envelope which reach 0.8w/m2.k and 20% WWR although the north façade still a light skin with 2w/m2k and 50% WWR. https://pserj.journals.ekb.eg/article_33376_ad7132fe61c6150f6d9ecb3c382db1b7.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Improved Hydrodynamic Performance of Stepped-Slope floating Breakwater using Submerged Horizontal Plate8163342810.21608/pserj.2017.33428ENEhabTolbaProfessor, Faculty of Engineering, Port Said University, Egypt,ElsayedGalalDepartment of Civil Engineering, Faculty of Engineering, Port Said University0000-0002-1079-1868A.Abou SeedaCivil Engineering, Higher institute of engineering and technology in New DamiettaJournal Article20170113Recently, the investigations on the hydrodynamic performance of floating breakwaters have great interest to<br />researchers because of its high advantages in protecting marinas and small craft harbors. For the purpose of improving<br />the hydrodynamic performance of the stepped-slope floating breakwater type, this research had been carried out as an<br />approach to investigate experimentally the resulting hydrodynamic performance of a composite pile supported<br />breakwater consists of a stepped-slope floating body moving only in heave motion overlying a fixed submerged<br />horizontal plate in a constant water depth, d = 30 cm. The transmission, reflection and losses coefficients had been<br />determined individually for each of the stepped-slope floating, fixed submerged horizontal plate and the composite<br />breakwaters. The results showed that the performance of the stepped-slope floating breakwater tested using different<br />relative draft values, Df /d, of the floating body had been significantly improved and achieved extra wave damping by<br />reducing the transmission coefficients by a ratio range between 23 % to 52 %, when using the submerged fixed<br />horizontal plate underneath the floating body, with definite improvement value depends on plate relative submergence<br />depth, dp /d and plate relative thickness, tp /d . For a composite breakwater using two relative submergence depths of the plate, it had been found that a significant higher wave attenuation takes place with a configuration using dp /d = 0.33<br />than that obtained when using dp /d = 0.50. Furthermore, plate relative thickness achieved wave attenuation<br />improvement for the composite breakwater especially for the configuration using dp /d = 0.33 and tp /d = 4%.https://pserj.journals.ekb.eg/article_33428_a3c92dff649f8a3b2dcaacee622c425c.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Assessment the Accuracy of Data Acquisition by Close Range Photogrammetry Technique in The Restoration of Historical Buildings17243343110.21608/pserj.2017.33431ENAteaya B.AzeezNational Authority for Remote Sensing and Space Sciences, Egypt,Ahmed M.AminCivil engineering department, Faculty of Engineering, Suez Canal University, Ismailia, EgyptAhmed I.El-HattabCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Ahmed A.El-sharkawyCivil Eng.

Therefore, continuous repair and maintenance for these valuable monuments and sites are usually needed. Preparing permanent precise records and documents for these monuments is the optimum way for their preservation. The purpose of this paper is to study, and assess the factors affecting the accuracy when using Close Range Photogrammetry (CRP) technique to reconstruct 3D objects. The façade of Coptic Museum and the AMR IBN AL-AAS Gate were chosen in this study. The results indicated that flatbed scanner with metric camera was acceptable in such cases when the photographed facades have no coarse details. whereas, nonmetric camera cannot be used in precise measurement. Also, it was concluded that using photogrammetry scanner with metric camera in close-range photogrammetry technique were acceptable for precise 3D restoration applications.https://pserj.journals.ekb.eg/article_33431_0d64b195f988a138b389cc3f94b08d97.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Comparison Between Terrestrial Laser Scanning and Close Range Photogrammetry for Three-Dimensional Modeling25303343310.21608/pserj.2017.33433ENAteaya B.AzeezNational Authority for Remote Sensing and Space Sciences, Egypt,Ahmed M.AminCivil engineering department, Faculty of Engineering, Suez Canal University, Ismailia, EgyptAhmed I.El-HattabCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Ahmed A.El-sharkawyCivil Eng.

The solution utilizes the derivative optimum of water benefit function and maximizes the benefit gained from the delivered water to reach the maximum water benefit MWB design solution. The solution is applied on a channel example and the results obtained are compared with those obtained by an earlier solution based on the minimum construction cost MC design of the channel only. The channel costs in both solutions are found to be of nearer magnitudes with little deviation. It is not necessary that the channel geometry in both cases must be identical, because the MWB solution depends on several factors such as; water benefit variables, pumping cost parameters and channel length, while the minimum cost MC solution depends on the channel cost parameters only. The MWB design solution is advantageous in that it achieves money gains even the delivered water is of cheap price, while this advantage is not satisfied in the earlier solution. However, the present study introduces an analytical solution for developing comprehensive water benefit and costing. The results of the given channel example involving pumping, demonstrate the simplicity and practicability of the MWB design solution as well as water benefit verificationhttps://pserj.journals.ekb.eg/article_33436_13b85cadaaa18174f5e862c338f83142.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Assessment of Recycled Concrete aggregates as an Aggregate for Roads41483343810.21608/pserj.2017.33438ENKamal G.SharobimCivil Engineering Department, Faculty of Engineering, Suez Canal University, Ismailia, Egypt.Nour Allah M.HusseinCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Mostafa HassanMarzoukCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Mohamed N.El-MansyFaculty of Engineering, Port Said University, Port Said, Egypt.Journal Article20170223The work discusses the incorporation of recycled aggregates (RA) in road pavement materials considering asphaltic concrete mixes and base or sub-base layers. Replacement of coarse RA instead of coarse natural aggregate (NA) in asphalt mixtures was investigated. It was found that the use of coarse RA in asphalt concrete mixes were complied with the Marshall technical specifications, but it may have insufficient durability due to their high susceptibility to water action which was evaluated using the retained stability test. These asphalt mixtures may be used in the underneath layers of road pavements such as base course layers, but it should be avoided in wearing or water proofing in the upper layers of pavements. On the other hand, the analysis of the RA materials required for using it as base or sub-base in roads were successfully in the range of specification limits. These materials could be incorporated and declared in the Egyptian specifications as an aggregate for roads.https://pserj.journals.ekb.eg/article_33438_eb8eec09a7859ceab2f3da881747280d.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301A Study to Distinguish Between Wastewater Treatment Plants in Rural Egypt49583344010.21608/pserj.2017.33440ENMamdouh Y.SalehCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Medhat H.El-ZaharCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Nehal M.AshourCivil Engineering Department, Faculty of Engineering, Port Said University, Port Said, Egypt.Journal Article20170303Several wastewater treatment plants technologies have been set up in the Egyptian villages; however, the most efficient and economical technology hasn't been determined.

Stagnant water areas could consist in isolated areas, artificial canals, islands, connection channels and structures that block the natural water flow. The properties of the water exchange rate of Damietta Port basin has been investigated as a response of relevant natural hydrodynamic drivers. A two-dimensional numerical model uses the equations of continuity and conservation of momentum was used to simulate the flow circulation patterns and tracking the pollutants transport in the port basin, depending on both water levels and wind data. The core of the work was to set up a hydrodynamic model for Damietta port, to determine the port basin hydrodynamic characteristics attitude. The tidal and wind data were used as input to the hydrodynamic model to simulate tidal currents in the port basin. Then, the results of the hydrodynamic model were analyzed to detect the tidal current characteristics and the general current patterns during a typical tidal cycle were simulated. Finally, the transport of pollutant particles in the port basin was simulated using the particle tracking technique in order to predict the pollutant particles movement. The results showed that the attitude of hydrodynamic characteristics of the port basin helps to make a good exchange of the fresh water between the port basin and the Mediterranean Sea.https://pserj.journals.ekb.eg/article_33443_7e5931317cd02e8e0edce25d843c9963.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Hydrodynamic Aspects of Staggered Spoilers fitted Subsea Pipelines87943344410.21608/pserj.2017.33444ENAhmedEl ShafeiDepartment of Mechanical Engineering, College of Engineering and Technology

Arab Academy for Science, Technology and Maritime Transport, Abu Kir, Alexandria, EGYPTJournal Article20170301Subsea pipelines are affected with many surrounding challenges. One of these challenges is the current-induced hydrodynamic stresses which affect the pipeline throughout its life span. Therefore, several methods have been suggested to reduce these stresses and hence protect the pipe. The aim of this paper is to investigate the effect of one of the protection methods; that is fitting the pipe with staggered spoilers along its length using computational fluid dynamics. A computational model based on Navies-Stokes for a single phase flow was developed to simulate the flow around the pipeline. Five turbulence models are used in the numerical investigation and their results are validated against the experimental data of a fully exposed pipeline resting on a plane boundary under various flow conditions. Comparison between flow field characteristics around the pipe with and without spoilers are conducted and discussed.https://pserj.journals.ekb.eg/article_33444_b341da049c21ab53943f468358768ed0.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Image Compression Using Advanced Optimization Algorithms951083344510.21608/pserj.2017.33445ENMohamed E.EmaraElectrical Engineering Department, Faculty of Engineering, Port-Said, EgyptRehab F.Abdel-KaderElectrical Engineering Department, Faculty of Engineering, Port-Said, EgyptMohamed S.YaseinElectrical Engineering Department, Faculty of Engineering, Port-Said, EgyptJournal Article20170201In this paper a new image compression schema that uses three-dimensional discrete cosine transform and relies on twodimensional discrete wavelet transform, for image classification, is proposed. The proposed technique utilizes a modified quantization table and a method for converting a three-dimensional image cube into a one-dimensional array, which provides better coding efficiency in the run length coding step. To ensure faster performance, this technique provides proposed parallel computation system. Several images have been used to test the proposed algorithm. Experimental results demonstrate that the proposed algorithm outperforms previous compression methods in terms of peak-signal-to-noise ratio with a lower compression bit rate.https://pserj.journals.ekb.eg/article_33445_a51d0634f7b57290cb5453f0e1588f03.pdfPort Said University, Faculty of EngineeringPort-Said Engineering Research Journal1110-660321120170301Increased Temperature Effect on Induction Motor Parameters1091153344610.21608/pserj.2017.33446ENNoura A.Nour Al-DinDepartment of Electrical Engineering -
