The lower infrastructural unit is represented by the northern dome \"A\" of Wadi Hafafit culmination which forms a macroscopic ovalshaped asymmetrical antifromal domal structure with a fold axis extends over 10 km in a NW-SE direction. It is differentiated into four structural subunits composed of interlayered sequences, mainly of para-granite gneisses, psammitic gneisses and paraamphibolites with medium to high-grade metamorphic facies. Granite gneisses and psammitic gneisses dominate the lower and the upper subunits, respectively, paraamphibolites dominate the second subunit, whereas the third subunit has subequal proportions of psammitic gneisses and amphibolites. The upper suprastructural unit is represented by Shait ophiolitic mélange domain (SOMD), which comprises deformed normally faulted thin-skinned napped sequence of low-grade metamorphosed volcanosedimentary island-arc type assemblages incorporating dismembered ophiolite and partially carbonated serpentinite fragments. Petrographic examinations carried out on both dome \"A\" and SOMD show distinct evidences of polyphase deformation (D1-D3) in addition to tow metamorphic events (M1-M2). Field data revealed that the exhumation of the Hafafit culmination domes to which the present dome \"A\" is considered and the large-scale crustal extension of SOMD run within a left-lateral dominated transpressional wrenching of Najd Shear System.","PeriodicalId":8568,"journal":{"name":"Assiut University Journal of Multidisciplinary Scientific Research","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74755040","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 electrical characterization of the developed reactor, including the current-voltage waveform and the consumed power, is investigated at different reactor configurations (including ground-electrode width, number of electrodes, and volume of the reactor) and operating parameters (including the air flow rates and energy density). The performance of the developed reactor for ozone production is evaluated. It is observed that the consumed power increased linearly with increasing the ground-electrode width and the number of electrodes, while the reactor volume and the flow rates have no noticeable effect on the consumed power. It is also found that the increase of the plasma area by increasing the width of the ground electrode is preferable than its increase by increasing the number of electrodes. This is attributed to the decrease of the power loss in the dielectric material. In addition, an optimum size of the reactor is obtained, as the higher and the smaller ratio of the reactor volume to the plasma area are not efficient.","PeriodicalId":8568,"journal":{"name":"Assiut University Journal of Multidisciplinary Scientific Research","volume":"487 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79983839","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}

One of the most important branches in data hiding is Steganography. Steganography techniques concerns with hiding the secret data within the cover image in order to avoid detection. Least Significant Bit (LSB) technique is used widely in steganographic images. The traditional LSB method replaces some LSB of the cover image with the secret data. In this paper, a new method based on LSB for image steganography is presented. The goal of the proposed method is to increase the embedding capacity and enhance the stego image quality. We invert LSBs of the cover image depending on the value of the secret data. The experimental results of this study indicate that our method achieves high capacity and good imperceptibility quality of the stego image.","PeriodicalId":8568,"journal":{"name":"Assiut University Journal of Multidisciplinary Scientific Research","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90345134","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}
