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.

Chinese Optics Letters 2014年第5期12卷 5-10页

作者： ahmed Nabih zaki Rashed Abd-Elnaser A. Mohammed Osama M.A. Dardeer Electronics and Electrical Communication Engineering Department Faculty of Electronic EngineeringMenofia University

A hybrid optical switch （HOS） with physical layer of wavelength division multiplexing and optical code division multiplexing （WDM/OCDM） scheme is proposed. An additional feature to the HOS than optical cross connect （OXC） is that the controller can process requests for both circuit establishment and burst scheduling. In our study, the measurement criteria of HOS are the blocking probability, probability of error, and probability of outage. To simplify the analysis, no distinction is made between a circuit in progress and a burst in progress. Moreover, a minimum fit （MinF） resource allocation strategy is applied in order to increase the bandwidth efficiency and control the multiplexing interference of the OCDM. A 2D Markov model for the HOS is presented using the MinF strategy. Numerical results reveal that the code parameters and the resource allocation strategy greatly affect the performance. Certain periority can be achieved by assigning shorter codes to high periority users and longer codes to low periority users. Also, the probability of error and outage are reduced bv aonling the MinF strategy.

Energy and Power Engineering 2015年第1期7卷 12-29页

作者： Manzar ahmed Uzma Amin Suhail Aftab zaki ahmed Electrical Engineering Department Faculty of Engineering University of South Asia Lahore Pakistan

Microgrid is a new concept in power generation. The Microgrid concept assumes a cluster of loads and micro sources operating as a single controllable system that provides both power and heat to its local area. Not much is known about Microgrid behavior as a whole system. Some models exist which describe the components of a Microgrid. In this paper, model of Microgrids with steady state and their transient responses to changing inputs are presented. Current models of a fuel cell, microturbines, wind turbine and solar cell have been discussed. Finally a complete model built of Microgrid including the power sources, their power electronics, and a load and mains model in MATLAB/Simulink is presented.

Global Energy Interconnection 2018年第3期1卷 301-311页

National and international policies encourage increased penetration of solar and wind energy into electrical networks in order to reduce greenhouse gas emission. Solar radiation and wind speed variations complicate the integration of wind and solar generation into power systems and delay the transition of these sources from centralized to distributed energy sources. The increased penetration of nontraditional energy sources into the electric grid stimulates the demand for large capacities in the field of energy storage. A mathematical model, which describes the operation of a proposed hybrid system, including solar PV, wind energy, and a pumped storage hydroelectric power plant is developed in this paper. This hydropower plant utilizes seawater as a lower reservoir, and only a tank has to be built in order to reduce the installation cost of the storing system. The pumped storage power plant used for compensation of the variation of the output energy from the PV and wind power plants by discharging water from the upper reservoir, which is previously pumped in the case of surplus energy from PV and wind turbine power plants. The impact of the proposed system on the grid utility is investigated in accordance with the values of energy exchange(deficits and surpluses of energy) between the considered hybrid system and the grid. The optimum design is determined by the pump and turbine capacities, upper reservoir volume, and the volume of water left in the tank for emergencies. Different scenarios of the optimum operations are presented for analysis. The results obtained from the examined scenarios indicate the ability of such a hybrid energy system to reduce the exchange of energy with the grid. This paper indicates the technical feasibility of seawater pumpedstorage hydropower plant for increasing the Egyptian national grid’s ability to accept high integration of renewable energy sources.

锂硫电池因其较高的理论容量和对环境友好等优势被视为极具发展潜力的储能装置,但是多硫化物的穿梭效应极大地限制了锂硫电池的实际应用。本文以葡萄糖为碳源,离子液体为氮源和硫源,KCl和ZnCl_(2)为模板剂,KOH为活化剂,通过热解工艺合成了氮硫共掺杂多孔碳(NSPC)。XPS和极性吸附实验表明N、S杂原子成功引入并且提高了碳材料对多硫化物的吸附能力,有效缓解多硫化物的穿梭效应,而较高的比表面积(1290.67 m^(2)·g^(-1))有助于提高硫负载量。负载70.1wt.%的硫后(S@NSPC)作为锂硫电池的正极材料表现出了良好的电化学性能。在167.5 mA·g^(-1)的电流密度下S@NSPC的首次放电容量为1229.2 mAh·g^(-1),远高于S@PC的861.6 mAh·g^(-1),且S@NSPC循环500圈后容量为328.1 mAh·g^(-1)。当电流密度从3350 mA·g^(-1)恢复至167.5 mA·g^(-1)时,可逆容量达到首圈放电比容量的80%,几乎恢复至其初始值。

Open Journal of Obstetrics and Gynecology 2021年第10期11卷 1342-1350页

Introduction: Ovarian cancer is the fourth most prevalent cancer among women and the seventh most common cancer overall. Every year, an estimated 200,000 cases and 125,000 deaths related to ovarian cancer are reported around the world. It is most common in high-resource countries, with an incidence rate of 9.3 per 100,000 women. Ovarian cancer is detected at an advanced stage in about 70% of instances, and only 30% of women with such cancers live for more than 5 years. Although only around 20% of ovarian cancers are limited to the ovaries at diagnosis, patients with localized disease have a 5-year survival rate of more than 90%. Peritonectomy is a crucial part of the surgical treatment for ovarian cancer. Visual inspection and palpation are not reliable methods for determining the extent of tumour involvement. The majority of gynecologic oncologists are suspicious about the benefits of a full peritonectomy, concerned about the benefits and hazards. They believe that the tumor’s fundamental biology, not surgical aggressiveness, dictates the tumor’s resectability. The aim of this work was primarily to compare the differences between total peritoneal gutter removal and random peritoneal biopsy in cases of early ovarian cancer. A secondary aim of this work is to show ability of total peritoneal gutter removal in relation to that of random peritoneal biopsy to detect positivity of metastasis in the histopathological specimens. Patients and Methods: This prospective cohort study was conducted on 130 patients with early ovarian cancer in El-Shatby hospital, Faculty
