Research ArticleOpen accessIn the author namesA Convolutional Neural Network Approach for Skin Lesion Classification Using Imbalanced Dataset with Image AugmentationZhyar Yassin Abdalla, Nor Hazlyna Harun, Mohammed Shihab AhmedA significant threat to people's health all over the world is skin cancer. The purpose of this research is to improve the detection of skin cancer by utilizing a CNN classification model that makes use of preprocessing and augmentation techniques. The HAM10000 dataset is used, and the imbalance it contains is addressed by resizing the images to 120×120 pixels and … …Journal of Computer Science, Vol. 20, Issue 11 · 10 Sep 2024 · 5,427 accessesView PDFCite
Research ArticleOpen accessIn the author namesMicroleakage Assessment of CAD/CAM Endo Crown Restorations (an in vitro Study)Mohamed Ahmed Wakwak, Karim Sherif Adly, Abdallah Ahmed Abdelhady, Ahmed Ramdan ElmanakhlyThe preservation of tooth structure is an important factor in the successful restoration of endodontically treated teeth. The loss of structural integrity increases the occurrence of crown fractures and microleakage at the margins of restorations in endodontically treated teeth compared with vital teeth. A total of twenty endocrowns were fabricated in this study and the endocrown was divided into two … …Current Research in Dentistry, Vol. 14, Issue 1 · 13 Apr 2023 · 6,179 accessesView PDFCite
Research ArticleOpen accessIn the author namesPhysico-Chemical Characteristics of Date Seed Oil Grown in SudanRehab Salih Mahmoud Abdalla, Alsheikh AlGilani Albasheer, Abdel Rahim Mohamed ELHussein, ELrasheed Ahmed GadkariemProblem statement: Studies were conducted on the physical-chemical properties of Sudanese date seed oil extracted from two date palm cultivars (Phoenix dactylifera L.) ALBarakawi and Alqundeila. The extracted oil from ALBarakawi seeds weighed 6.833% w/w oil, Alqundeila oil extracted weighed 5.064% w/w. Approach: The physical properties of ALBarakawi oil were: viscosity: 17cp, refractive Index: 1.444, density: 0.9116 g cm-3 color: … …American Journal of Applied Sciences, Vol. 9, Issue 7 · 5 May 2012 · 9,500 accessesView PDFCite
Research ArticleOpen accessIn the author namesSolving Two Deadlock Cycles through Neighbor Replication on Grid Deadlock Detection ModelNoriyani Mohd Zin, A. Noraziah, Ahmed N. Abdalla, Ainul Azila CheFauziA data grid is compose of hundreds of geographically distributed computers and storage resources usually locate under different places and enables users to share data and other resources.
