Due to the difficulties of brain tumor segmentation, this paper proposes a strategy for extracting brain tumors from three-dimensional magneticResonance Image (mRI) and Computed Tomography (CT) scans utilizing3D U-Net Design and ResNet50, taken after by conventional classificationstrategies. In this inquire, the ResNet50 picked up accuracy with 98.96%, andthe 3D U-Net scored 97.99% among the different methods of deep *** is to be mentioned that traditional Convolutional Neural Network (CNN)gives 97.90% accuracy on top of the 3D mRI. In expansion, the imagefusion approach combines the multimodal images and makes a fused image toextricate more highlights from the medical images. Other than that, we haveidentified the loss function by utilizing several dice measurements approachand received Dice Result on top of a specific test case. The average mean scoreof dice coefficient and soft dice loss for three test cases was 0.0980. At thesame time, for two test cases, the sensitivity and specification were recordedto be 0.0211 and 0.5867 using patch level predictions. On the other hand,a software integration pipeline was integrated to deploy the concentratedmodel into the webserver for accessing it from the software system using theRepresentational state transfer (REST) API. Eventually, the suggested modelswere validated through the Area Under the Curve–Receiver CharacteristicOperator (AUC–ROC) curve and Confusion matrix and compared with theexisting research articles to understand the underlying problem. ThroughComparative Analysis, we have extracted meaningful insights regarding braintumour segmentation and figured out potential gaps. Nevertheless, the proposed model can be adjustable in daily life and the healthcare domain to identify the infected regions and cancer of the brain through various imagingmodalities.

The Electromagnetic Field Propagation in a Spherical Core

引用

Journal of Electromagnetic Analysis and Applications 2012年第12期4卷 481-484页

作者： osama m. Abo-Seid Ghada m. Sami mathematic Department Faculty of Science Ain shams University Cairo Egypt. mathematic Department Faculty of Science Kafr El-Sheikh University Kafr El-Sheikh Egypt

A simple and explicit derivation for the electric and magnetic fields in the ferromagnetic cores has been studied. An improved model for analyzing the distribution of electric and magnetic fields in a toroidal core is given. This leads to a basis system for the theoretical analysis of iron loss in the magnetic cores, so, the theoretical results have been evaluated. A method is used to perform numeric calculations of the magnetic field produced by the eddy current and displacement current due to the electric field which shield the magnetic flux from the inner portion of the core cross section. The results obtained from this work could be used to evaluate the skin effect in the conductors of a winding.

medium-Term Electric Load Forecasting Using multivariable Linear and Non-Linear Regression

引用

Smart Grid and Renewable Energy 2011年第2期2卷 126-135页

作者： Nazih Abu-Shikhah Fawwaz Elkarmi osama m. Aloquili 不详

medium-term forecasting is an important category of electric load forecasting that covers a time span of up to one year ahead. It suits outage and maintenance planning, as well as load switching operation. We propose a new methodol-ogy that uses hourly daily loads to predict the next year hourly loads, and hence predict the peak loads expected to be reached in the next coming year. The technique is based on implementing multivariable regression on previous year's hourly loads. Three regression models are investigated in this research: the linear, the polynomial, and the exponential power. The proposed models are applied to real loads of the Jordanian power system. Results obtained using the pro-posed methods showed that their performance is close and they outperform results obtained using the widely used ex-ponential regression technique. moreover, peak load prediction has about 90% accuracy using the proposed method-ology. The methods are generic and simple and can be implemented to hourly loads of any power system. No extra in-formation other than the hourly loads is required.
