<strong>Transport network planning in Egypt suffers from insufficient planning that should be done prior to execution. This research presses on the fact that personal experience and cognition alone cannot be the main factors of design that it should go hand in hand with scientific measurable analysis and evidence. Hence, it focuses on having a deeper understanding of the influence of spatial network configuration on urban activity and centrality. It proposes that Space Syntax, as a syntactic model, has potential to be utilized in optimizing transportation networks, based on Space Syntax ability to model and predict streets with most urban activity and areas that act as central gathering points, and therefore, giving a scientific basis to evident decisions to choose optimum routes and stations for transit networks. The study hypothesizes that adding Space Syntax spatial configuration analysis as a layer to the whole process can give a better understanding of the network. This research applies Space Syntax configurational analysis with the aim to present an evidence approach to optimize its transportation network. The proposed approach is applied on Mansoura City, an intermediate city in Dakahlia governorate in Egypt. The methodology includes field observations using gate counting technique to identify movement flows in different parts of the city, running a segment map analysis of the city’s street network and validating the results of the analysis through comparing computed values with observations. Results identify streets with major urban movement which represent potential transit routes and areas that are considered urban centers which represent potential transit stations. These results verify the important role of accessibility analysis in transportation planning, and therefore presents an applicable approach to identify optimum transit routes and stations that have higher potential to act as active movement corridors at a city scale.</strong>

<strong>Streets are the most flexible elements in the city where its boundaries are drawn by the boundaries of buildings and properties, and the primary means of planning new streets and the surrounding environment surrounding them is to develop a two-dimensional plan, but this plan is criticized at times because of its inability to take the 3D world in Consideration and consequently their inability to predict the actual outcome of the plan</strong><strong>, And to address this criticism, this paper explores empirically whether visual distributions can be</strong><strong>predicted through a two-dimensional plan. Experiments and research were conducted in Sweden on a set of images through the eye tracking system, </strong><strong>and human visual attention was measured to street types: ( Blocked, open, curved, angle), The results show that different types of visual attention are evoked by each of the four different street types.</strong><br clear="ALL" /> <strong>Consequently, the research aims to study the two-dimensional plans that are studied through the eye tracking system, and to study its ability to predict future three-dimensional results of a particular plan in terms of visual attention, and then move to the research methodology and through it will come out with a set of indicators through studying previous experiences To use the eye tracking system, these indicators are valuable for planners, architects and decision makers when planning new urban environments through the importance of understanding the human perception of streets in a broader context.</strong>

<strong>Heritage buildings are one of the most important sources of energy consumption in the world. As a result, direct and indirect regulatory laws in the European Union through energy efficiency in the buildings stipulated the importance of rationalizing energy consumption in buildings through application to existing buildings and not ignoring the architectural heritage in general, which adopts the energy rationalization system Especially the traditional residential buildings that are architecturally abstract, like historical buildings.</strong><br /> <strong>Therefore, any country can adopt these laws to annex or exclude buildings by following the energy efficiency requirements of the existing buildings and there is no global law in the field of architectural heritage dealing with renewable energy.</strong><br /> <strong>The research bridges this gap between historical buildings and the renewal of energy, which is the goal of those responsible for the national cultural heritage, as well as the trend of world policy towards energy renewal in buildings</strong>

<strong>Masonry units are considered to be traditional and environmental materials used in constructing valuable buildings in historic and Heritage sites all over the world. And they are well known for either construction or claddings up-till now. But they sound for various problems while using them in traditional ways as; the massive weight, the limitations of constructing large spans, the low durability while absorbing water or facing more stresses. Moreover, they are costly while maintaining them.</strong><br /><strong>Nowadays the call for sustainable development forced technology to convert the massive material to a smart one which could deal in the site with efficiency as economically or environmentally as called eco- efficient aspects. So the liability issue is that; there is no researches (especially in Egypt in the field of the conservation of the heritage buildings) refer to the usage of the smart masonry in the heritage buildings or the advantages that could be gained by that usage.</strong><br /><strong>The research aim to get important role of smart technology to search for the aspects of efficiency that could be presented in the global era to get solutions to revive the usage of masonry units in the heritage buildings in new integrated constructions or in the additions of the heritage buildings themselves, all within the scope of the sustainable development.</strong><br /><strong>There are two hypotheses in the paper as follows; the first considering that the global technology afforded the construction process by smart materials and systems that can represent many kinds of efficiency suiting the sustainable development.</strong><br /><strong>The second hypothesis: is that the smart masonry have great efficiency while using them in the rehabilitation projects of the heritage site.</strong><br clear="ALL" /><strong>The methodology used in this paper to fulfill the hypothesis and reach the main aims is a deductive method begins with a theory(Displaying the new technical masonry and their advantages as means of reaching eco efficiency), and developing hypotheses from that theory(by Assessing the validity of the hypothesis concerning the needed efficiencies of the used construction in the heritage sites, by means of questionnaire directed to the persons concerned the heritage sites development), and then collecting and analyzing data to test those hypotheses(by measuring the efficiency of using the new technical masonry in the additions of the constructions in the heritage buildings, by means of questionnaire directed to the persons concerned the heritage sites development</strong><strong>civil engineers and industrialists).</strong>

<strong>Open social space is a physical space such as social center, sports club, parks or other gathering places where people gather and interact.</strong><br /> <strong>The aim of the research is to suggest design alternatives to deal with the negative impacts of social distancing to fulfil users' needs to perform their social activities in open social spaces during the spread of infectious viruses such as COVID-19.</strong><br /> <strong>The research methodology was relied on an inductive approach to acknowledge the different levels of social spaces between individuals and the real reasons why applying social distancing is difficult to verify inside social open spaces to meet individuals' needs to perform social activities. An analytical method was also applied in the study of open social space within the Smash Sports Academy to monitor the effects of implementing social distancing in the design of open social spaces. </strong><br /> <strong>Finally, the conclusion reached a set of results, including the cultural and economic level of individuals practicing activities inside open social spaces is correlated to their level of perception to the importance of social distancing on public health. Nevertheless, the social heritage of societies remains a key factor in the extent to which individuals perceive spaces and the manner of carrying out activities within them.</strong>

<strong>It is always essential for all public spaces to incorporate various factors that help any public space play its vital role in the City, including quality, quantity, accessibility, and connectivity of such spaces to their local communities. This Paper Investigates the vital role of Public Spaces as Socio-cultural Hubs needed for society's well-being, especially in metropolitan cities. With an essential question of developing such spaces as multi-purpose and critical challenges, such spaces are supposed to adapt to their cultural & environmental contexts, thus leading to better socio-cultural interaction. Fulfilling The critical use of public space where people can enjoy their social life and co-existence, representing their interests so that nothing is disaggregating or drowning for their diversity. The Paper also sheds light on public spaces' failure to get proper attention despite their importance. A literature overview is done for public spaces, with a focus on the UN habitat in collaboration with other partner institutions toolkit of Global public space as a user-friendly guide, and how to improve the quality and distribution of public spaces and how to make them available and accessible for the public in addition to the practice guidelines. This Paper highlights the need for Public Spaces in Cairo, Urban Challenges in this concern, and how proper actions and measures should be taken. Policies can be made accordingly for the public space developmental plans in Cairo. Considering the urgent need for Public spaces That widely reflect such Rich and diversified culture and Local Identity, the Paper ends with some suggested guidelines based on the Theoretical review and Analytical studies, in addition to some Recommendations.</strong>

<strong>The informal economy occupies a major position in the structure of urban communities, its presence and intensity poses many problems and challenges for the development of urban communities. For the importance of the spatial dimension of informal economy activities and the overlapping issues of informal housing, unemployment, poverty and social marginalization… etc., we must study the dynamic relationship between informal sector activities and housing system. The first part of the research focused on the spatial dimensions of the informal economy and a typology of activities in this sector comprising home-based activities, itinerant informal economy workers, and sedentary commercial & artisanal activities located outside the home. Then the research presents a set of correlative elements between informal sector activities and housing system, the most important of which is housing and its surroundings, sites allocated for housing, The spatial distribution of the commercial activities, public space, mobility and transportation, social interaction, and up to the main actors in the housing stocks. The second part of the research is the analytical study of the above elements on Ezbet Khairallah and Othman housing “before and after Residents alterations”. A comparative analysis has shown that where the planning system has failed to provide for the space needs of informal economic activities, operators have eventually found ways of meeting this need, often in spaces where such activities are not permitted. The research ends with the dynamic relationship between the informal sector activities and the housing system, also the importance of learning from informality in spatial planning, the need to adopt an integrated development approach and complement measures needed to effectively address the space needs of informal economy businesses in the urban development process</strong>

<strong>The research deals with defining the desert hinterland, its locations in the delta of Egypt, its most important development goals, and methods of applying some criteria (natural, environmental - urban, infrastructure - economic and human), and accordingly a quadruple analysis was made on several criteria and through this the study area - Burullus - was determined. He presented all the criteria, the most important of which is renewable energy, through knowing the renewable energies in the study area, how to use it and its most important applications, through which it provides the opportunity to contribute to achieving a number of important goals for sustainable development, including the following: (1) social and economic development, (2) benefit from Energy, (3) energy security, (4) mitigation of climate change impacts and reduction of environmental and health impacts. Mitigating the dangerous impacts of anthropogenic climate change is considered one of the strong driving forces behind the increase in the use of renewable energy around the world.</strong><br /> <strong>It also shows the strong relationship between renewable energies and the environment, as their exploitation leads to reducing pollution and preserving the environment, which leads to raising the area environmentally and transforming Burullus into a natural reserve to be a tourist factor in the study area, which allows the work of the proposed development plan that is not exploited (in the absence of an environmental thought for development) and becomes the region A center for the exploitation of renewable energies and the preservation of the environment, especially as the delta region is low and threatened with drowning due to the global warming process resulting from pollution.</strong>

<strong>A modified sequencing batch reactor (MSBR) was developed by installing six fiber vertical plates of specific surface area of 180 cm<sup>2</sup>/ L in conventional sequencing batch reactor (SBR), which designed for supporting the biofilm formation and increasing the system efficiency. In this study, the effect of increasing the organic loading rate of 281.25 g COD/m<sup>3</sup>. d by 33%, 67%, and 100 % on the performance of SBR and MSBR was investigated. The effluent BOD<sub>5</sub>, COD and TSS of the MSBR at high organic loading rate was 20, 32 and 27 mg /L, respectively, while for conventional SBR was 34, 58 and 45 mg /L, respectively. The total bio-sludge of MSBR was more than that of conventional SBR by about 30% resulting in a reduction of the F/M value. The sludge volume index (SVI) in MSBR was lower than that of conventional SBR by about 33%. MSBR system was able to treat municipal wastewater with high performance.</strong>

<strong>Updating large-scale maps is one of the main problems in Egypt. These maps can be either many years out of date or even non-existent. On the other hand, the recent enhancements that have been made to the spatial resolution of remote sensing imagery have more accurately enabled the modeling of the Earth's surface features at short intervals. So, if the current High-Resolution Satellite Images (HRSI) are corrected from available geo-referenced topographic maps, digital layers for different applications will be available, as well as rationalization of national budget that are spent on their updating will be offered. In the current research, high resolution satellite images of world view-3 dated 2018, have been corrected geometrically using polynomial model. This model depend on the selection of several ground control points (GCPs) on the distorted image and map them to their true locations in ground coordinates measured from geo-referenced topographic maps. The geometric corrections accuracy of resulted image had been assessed quantitatively and qualitatively. The suitable scale for producing GIS layers from HRSI was also determined. The final result of the experimental works of geometric correction of HRSI using eight ground control points was calculated (Average of RMS error of image = 0.27m), and also the result of the positioning errors using eleven check points available for accuracy quantitative assessment was calculated as (2.59m). The output suitable scale maps for layers production is 1:5000, calculated depending on planimetric allowable accuracy (RMS), taking into consideration the standards of 0.5 mm of map scale.</strong>

<strong>Currently, there is a crucial demand to construct affordable housing which can be achieved by producing building materials that are characterized as low cost and environmentally friendly sustainable materials. Many researches have been carried out to develop such materials. One of the most common trends in this regard is using stabilized soil that can be compressed in steel moulds to produce masonry units. The produced units are therefore named “Compressed Stabilized Earth Blocks; CSEB”. However, there is still necessity to better understand their physical and mechanical properties under different service conditions in order to evaluate the viability of such masonry units. The experimental program designed for this study included casting 96 50mm cubes. Specimens were categorized according to different proportions of silt, sand and stabilizing materials. The stabilizing materials used were cement, bitumen, and white gluten. Specimens were tested in compression to determine their compressive strength at 7 and 28-day. Specimens were also tested to determine the water absorption of each mixture. Results show that cement is the best stabilizing material among the examined materials. There is a specific percentage of stabilizing material that gives the maximum compressive strength, after which adding more stabilizing material reduces the compressive strength</strong>

<strong>Basra governorate represents one of the most important governorates in Iraq, where it is the only seaport for exporting oil and agriculture products. However, this governorate is facing serious land degradation problems results in major changes in land use/ cover (LULC) within the area. Accordingly, the main objective of this study was to evaluate LULC in Basra city using different techniques on remotely sensed data. For that purpose, Landsat 8, Sentinel 2A images were used in 2018 to study extent of urban areas, agricultural lands, water bodies and bare lands areas in Basra city center. The studied techniques include: the supervised classification in three methods (minimum distance, maximum likelihood, and Mahalanobis distance), spectral indices, manual digitizing of features and land surface temperature (LST). These methods were applied on both Sentinel 2A and Landsat data at three spatial resolutions 10, 15 and 30 m, respectively. The obtained results indicated that the minimum distance technique has the highest accuracy in identifying LULC when compared with the other classification methods. It was found that the higher the spatial resolution the higher the accuracy of the results. The spectral indices were more accurate than the classification methods in identifying agricultural areas and water bodies. There was a higher inclusion between urban areas and bare lands due to the similarity in their spectral reflectance. Accordingly, it is recommended to manually digitize urban areas than classifying it. The LST can be used as an indirect and fairly accurate method for evaluating LULC in Al-Basra city.</strong><br clear="ALL" /> <strong>In conclusion, remote sensing data and techniques could help in providing more accurate information about LULC in Basra City to be used in its future planning and sustainable development</strong>

<strong>Stone matrix asphalt (SMA) is a gap graded hot mix asphalt (HMA) which gains its main strength from stone on stone contact. It provides a rut-resistant, durable surfacing material which is suitable for heavily trafficked roads. Typical SMA consists of 70-80 % coarse aggregate, 8-12 % mineral fillers, and 6-7 % binder.</strong><br /> <strong>Due to this high binder content, stabilizing additives are needed to prevent draindown that might occur during transport and placement. According to SMA standards, cellulose and mineral fibers are the most suitable stabilizing additives to be used in SMA, but due to lack of those specific types of fibers in some countries, another types of fibers are being tested to replace them in the mix.</strong><br /> <strong>The main objective of this study is to investigate the characteristics of SMA mixtures using fiberglass as a stabilizing additive. Another SMA mix of the best result was prepared using polypropylene fiber instead of fiberglass and tested for comparison purposes.</strong><br clear="ALL" /> <strong>Two different SMA gradations were tested, nominal maximum aggregate size (NMAS) 12.50 mm and NMAS 19.00 mm at four different fiber contents for each gradation 0.00 %, 0.30 %, 0.50 %, and 0.70 % by total weight of the mix. SMA samples were tested through series of performance tests selected to be Marshall stability test, moisture susceptibility test, indirect tensile strength test (ITS), and draindown test.</strong>

<strong>Diabetic Retinopathy (DR) is one of the main causes of blindness that can be overcome, if it is early detected. This work proposes an automated early detection and grading of DR using fundus images. The proposed detection and grading system investigate different deep learning architectures (i.e., ResNet and AlexNet) that are applied to an augment data to extract deep compact features of the fundus images. The extracted features are input to a pixel-wise Neural Network (NN) classifier or a Support Vector Machine (SVM) classifier for automated DR grading. The performance of the proposed system is evaluated using a publically available fundus Indian Diabetic Retinopathy Image Dataset (IDRiD), collected for ISBI-2018 challenge. The IDRiD dataset consists of 516 retinal images of normal and different DR grades, i.e., mild, moderate, severe, and Proliferative Diabetic Retinopathy (PDR). Our system achieves an overall accuracy of 95.73%, sensitivity of 95.73%, and specificity of 98.51% utilizing an AlexNet-based architecture and a pixel-wise NN classifier. Compared to the previous related work, the proposed system shows promising DR grading performance.</strong>

<strong>Photovoltaic (PV) water-pumping systems have considerable cost-effective value in rural zones. Virtual flow rate (VFR) meter is a technique to measure the water flow rate through a water pump using a numerical method as a function of the pump head, motor power, and overall efficiency of the pump. VFR meter eliminates the need for rotor speed sensors in PV water pumping systems. In this paper, the virtual flow meter is proposed as a novel reference for improving maximum power point tracking (MPPT) algorithms for PV water-pumping systems. VFR meter removes the expensive flow meter sensors, hence, reducing the overall costs of the system. The VFR will be represented as a new variable in the MPPT algorithm. By replacing the voltage with the instantaneous VFR, the system will operate based on the variation of the VFR meter measurements. Using the physical parameters of a submersible Brushless DC motor pump-based PV water-pumping system, a mathematical model is derived to obtain the input voltage to MPPT algorithm as a function of the instantaneous flow rate. The model is implemented by Mat lab/Simulink software and the results reveal the applicability and efficiency of using the virtual flow meter in MPPT algorithms<em>.</em></strong>

<strong>Analysis of a hybrid system, comprising of photovoltaic (PV), diesel engine generators (DEGs) and solid oxide fuel cells (SOFCs) is proposed in this study for a stand-alone micro grid. This proposal system is a source for energy in a typical city in Egypt. The component specifications of the hybrid system were discussed. Ammonia (NH<sub>3</sub>) is a hydrogen supply for the fuel cell is clarified in this work. The hydrogen generating from synthesizing ammonia from nitrogen and hydrogen separated with renewable energy is applied to generate electrical power from the SOFC. In the present paper, the operation plan of the proposed system is optimized as a non-linear system without using battery. In addition, the analysis of the overall efficiency is shown. The operational advantages of the system were clarified. Using PV power contribution reduces the fuel consumption of the system by 33% compared by the hybrid system without using renewable energy. Moreover, this paper reported that there are reductions in fuel consumption of the proposed system with using ammonia synthesizing by 25% compared with the same hybrid system without using NH3. The methods proposed in this work can be applied to develop comprehensive analyses in energy storage solutions using a hydrogen carrier in hybrid systems and micro grids. Moreover, increasing the efficiency and decreasing the operating cost are the advantages of powering a stand-alone micro-grid using this hybrid system; so this is proposed hybrid system becomes more economic than other hybrid systems.</strong>

<strong>In this paper, a system based on deep learning and majority voting is proposed for joint segmentation of the liver and hepatic tumors. The proposed system is composed of three steps. First, deep learning is utilized to extract deep features that describe the Computed Tomography (CT) images as well as cancerous nodules, using three different Convolutional Neural Networks (CNNs), i.e., VGG16-Segnet, Encoder-Decoder (ED)-Alexnet, and Resnet18. Second, a classification step using the extracted deep learning features is performed for each investigated network. To produce the final liver and hepatic tumor segmentation, the last step applies a majority voting technique to fuse the three utilized CNN outputs. To test the performance of the proposed system, the MICCAI LITS challenge database is used, composed of 130 CT volumes with a total of 16,917 cross-section images. The proposed system achieves Dice Similarity Coefficients (DSCs) of 94% and 76% for liver and lesion segmentations, respectively. Comparison with the related methods confirms the promise of the proposed system for joint liver and tumor segmentations</strong>

<strong>The industrial revolution in Egypt and other developing countries need a huge amount of power, while utility could not be able to provide the needed energy and both the cost of energy and environmental issues should be also considered. So, energy saving can be one of the effective solutions to such problems. Demand Side Management (DSM) can be introduced as an effective system management for increasing the efficiency of the grid as it can save energy to both utility and consumer. DSM has different techniques including load shifting strategy that reshapes the load curve to reduce the peak demand and hence the overall total cost. </strong><br clear="ALL" /> <strong>In this study a granite factory is considered as a case study where the load shifting technique is applied in order to reduce the running cost. The applied optimization technique cost function mainly depends on three main parameters: electrical cost (which is divided into on-peak and off-peak periods), demand cost (depends on the maximum utilized power) and workers’ wages (based on night or day shifts). Two different optimization techniques are applied and compared to get the best optimal results. The first technique is Particle Swarm Optimization (PSO) and the second technique is CVX that has been introduced and implemented in MATLAB® 2017 as a guide optimization reference technique. By comparing the results from different operating conditions and constraints, it was found that the load shifting technique can reduce the peak demand cost, while increasing in running cost has been noticed. So, the shut-down period has been suggested and studied by CVX, and PSO in order to reduce both peak demand cost and running cost. Saving in cost is achieved by using PSO more than CVX.</strong>

<strong>This work presents a method for classification and segmentation of brain tumors based on deep learning analysis of brain contrast T1 (T1c) MR images. To achieve this goal, three different deep learning networks are investigated i.e., U-Net, VGG16-Segnet, and DeepLabv3+ models. In addition, the integration of the 3D narrow-band information of the MRI volumes is imported to the input of the Convolutional Neural Network (CNN) to describe more accurately the tumor anatomy. Experimentations are performed on the MICCAI’2018 High Grade Glioma (HGG) subset of the Brain Tumor Segmentation (BraTS) Challenge, composed of 210 brain T1c MRI volumes, each of 155 cross-sections. Among the three investigated CNNs, DeepLabv3+ network achieves the highest Dice Similarity Coefficients (DSC) of 91.2%, 92.5%, 94.6% for the segmentation of the Enhancing Tumor (ET), the Tumor Core (TC), and the Whole Tumor (WT), respectively.
