The importance of the economic factor in the development process was emphasized in most development theories, by determining the most suitable investment locations and the best delivery of activities and services based on the best relationships. Afterwards, some Arab and international experiences were examined, which discussed the topic of research based on an analytical study of various economic considerations, and different scenarios were used to set development plans based on the priorities for achieving goals that differed by country. The study assumes that the lack of developmental balance between the city and its region is due to land use inconsistency and a lack of long-term planning for available resources and development potential. This resulted in the loss of many commercial and development prospects, a decline in agricultural output, and a rise in real estate rents in the surrounding areas of big cities in general, and Aleppo in particular. To track the problem, we used the historical method, the inductive method to read the facts, the deductive method to elicit the sources of the problem, the analytical method to analyze the causes, and the results were formulated using the analysis. Then, based on the strategies, theories, and experiences studied in the first topic, a development strategy was proposed based on the development indicators of the Greater Aleppo City region. To promote sustainable growth in the country, this strategy seeks to reduce development disparities throughout the region and achieve equity in the distribution of economic activity.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"49 5 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87692435","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper presents an integrated secure model for the healthcare system in cloud computing that achieves the security and confidentiality of data transferred through cloud computing, by combining the two algorithms AES and RSA with the access control algorithm CP-ABE in order to use the advantages of each of them, where the encryption process is done by a proposed algorithm which is based on the RSA algorithm, the XOR parameter, and the AES algorithm; the secrecy of the AES algorithm has been increased by generating a dynamic key, and the confidentiality of this key has been secured with two encryption levels, the first level using the CP-ABE algorithm and the second level using the RSA algorithm. The proposed model is characterized by meeting the requirements of access control, authentication, and verification for both the transmitter and the receiver, and the results of the application of this model proved its ability to meet the security requirements of the health care system in cloud computing with the lowest possible implementation time, as the execution times were at the transmitter's end (43.2, 43.83, 45.11, 48. 23, 50.77, 52.16, 57.95, 63.2, and 63.35)ms for variable file sizes (37, 50, 100, 150, 200, 256, 512, 1000, and 1024)KB, respectively.

Radiography technology is a very important technique in the medical community to detect diseases and abnormalities that may be present, but the interpretation of these images may take a long time and it is subject to error by radiologists who are exposed to external practical factors (such as fatigue resulting from working for long hours, or exhaustion, or thinking about other life matters). To assist radiologists, we have worked on developing a diagnostic model with the help of a deep learning technique to classify radiographic images into two classes: (Normal and Abnormal images), by transferring the selected deep convolutional neural network between a large group of available networks that we studied on the basis of the regions that possibly abnormalities provided by the radiologists for the study sample.

This paper illustrates a simulation of a NACA four digits airfoil blade profile using MATLAB. As airfoil design became more sophisticated, this basic approach has been modified to include additional variables, and suggestions for the chord line length at the root and at the end of the blade. as well as changes in the twisting angle of the blade and its thickness, this helps to reduce the weight of the blade significantly Simulating NACA equations is very useful in obtaining coordinates of airfoil curvature for the whole series of NACA four digits, which is very effective in optimizing blade design. In order to get an optimal operating performance and high efficiency for the airfoil, the blade surface must be smooth and does not suffer any discontinuities or undefined cases, which cause separation of the boundary layer during the airflow, and get as a result great energy losses. Therefore, the conditions for the continuity of the blade was extracted using mathematical analysis, so the air flow does not suffer any interruptions which reduce the efficiency. This enable us to determine the locations of the maximum thickness of the blade sections on the chord along the blade, in addition to specifying conditions for the chord line length at the root and at the end of the blade which keep the blade curvature continuous and doesn’t have any irregular points, which also facilities writing the necessary programs.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"59 6 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79758899","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The flat slabs are an ideal solution that guarantees the speed and ease of implementation, especially in multi-storey buildings. The phenomenon of punching is a fundamental defect in these slabs, and the Syrian code addressed it to treat it in traditional ways such as making crowns for columns or falls of beams, which creates architectural and technological defects. The research includes conducting laboratory experiments on reinforced concrete slabs and analyzing the results with the aim of strengthening the flat slabs punching within the same thickness of the approved slab by linking the lower and upper reinforcement steel which provides a working principle similar to the trusses. The strength was made using shear studs (distribution case, matrix or diagonal), which in turn raised the efficiency of flat concrete slabs on the punching in terms of durability, deformations, and the breakdown mechanism in this case. The importance of the research lies in the use of locally manufactured elements within the workshop without the need for ready-made shear studs, which reflects positively on the cost and time of implementation.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"39 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80593837","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The aluminum rods (Billets) are heated and pressed through a die to obtain the required profile. The research aims to study the effect of Pocket height when using zero bearing dies by modeling using the INSPIRE EXTRUDE METAL program package for a single rectangular section of 65 mm in length and 1.5 mm in width, and then to conduct experimental verification of the results by designing, manufacturing and testing a real mold in an aluminum extrusion factory that matches one of the molds Studied. As we studied a group of molds that have a Pocket so that the height of the pocket in them changes from zero (a reference flat die) to a height of 20 mm. The feeder design takes into account the homogenization of the flow across the studied section, which narrows in the center and widens at the edges. The measurement of the relative flow velocity at the front of the section was used as an indicator to analyze the results of the analytical experiment. The study showed that a certain height of the feeder of 10 mm must be maintained for the studied section. The FEM results and the practical experience were identical. This shows the importance of the FEM and its effectiveness in shortening the experimental work and that it can, to a large extent, save time and effort to manufacture, test and correct dies.","PeriodicalId":15747,"journal":{"name":"Journal of engineering sciences and information technology","volume":"3 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88154887","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
