Cancer of the breast is one of the world's most prevalent causes of death for women. Early and efficient identification is important for can care choices and reducing mortality. Mammography is the most effective early breast cancer detection process. Radiologists cannot however make a detailed and reliable assessment of mammograms due to fatigue or poor image quality. The main aim of this work is to establish a new approach to help radiologists identify anomalies and improve diagnostic precision. The proposed method has been applied through the implementation of preprocessing then segmentation of the images to get the region of interest that was used to find a texture features that were calculated based on first Order (statistical features), Gray-Level Co-Occurrence Matrix (GLCM), and Local Binary Patterns LBP (LBP). In the features selection phase mutual information (MI) algorithm is applied to choose from the extracted features collection suitable features. Finally, Multilayer Perceptron has been applied in two stages to classify the mammography images first to normal or abnormal, and secondly, classification of abnormal images into benign or malignant images. This method was implemented and gave an accuracy of 92.91 % for the first level and 93.15% for the second level classification.
乳腺癌是世界上最普遍的女性死亡原因之一。早期和有效的识别对于可选择的护理和降低死亡率非常重要。乳房x光检查是最有效的早期乳腺癌检测方法。然而,由于疲劳或图像质量差,放射科医生无法对乳房x光片进行详细和可靠的评估。这项工作的主要目的是建立一种新的方法来帮助放射科医生识别异常并提高诊断精度。该方法通过对图像进行预处理,然后对图像进行分割,得到感兴趣的区域,用于寻找基于一阶(统计特征)、灰度共生矩阵(GLCM)和局部二值模式LBP (LBP)计算的纹理特征。在特征选择阶段,采用互信息算法从提取的特征集合中选择合适的特征。最后,将Multilayer Perceptron分两个阶段应用于乳房x线图像的分类,首先是将乳房x线图像分类为正常或异常,其次是将异常图像分类为良性或恶性图像。结果表明,该方法的一级分类准确率为92.91%,二级分类准确率为93.15%。

Evaluation of Atmospheric Blocking Effects on Weather Events in Iraq 大气阻塞对伊拉克天气事件的影响评价
Pub Date : 2020-12-20 DOI: 10.23851/MJS.V31I4.705

Atmospheric blocking has received a lot of attention in recent years due to its impacts on mid-latitude circulation and then on weather extremes such as cold spells, heat waves, drought, and heavy rain. In this paper, the effects of atmospheric blocking on weather events ''rainfall in particular'' over Iraq are evaluated. Daily meteorological data from the National Centers for Environmental Prediction (NCEP) for the period 2002-2018 were analyzed to identify different atmospheric blocking systems over Iraq and surrounded regions. In order to locate the blocks on maps, the study domain is extended from 10-70o N and 10-70o E for mean sea level pressure. This study state two cases of Omega blocking system occurred on 25 Jan 2006 and 01-03 Feb 2006. Rainfall observed by the Tropical Rainfall Measurements Mission (TRMM) along with true color cloud images detected by the Moderate Resolution Imaging Spectrora-diometer (MODIS) were employed for determining the severity and trajectory of rainstorms associated with atmospheric blocking systems. NCEP provides data with a spatial resolution of 2.5o × 2.5o while TRMM is 0.25o × 0.25o. Analysis of one typical year (2016) showed that among 24 blocking systems detected during the period of this work, 37.5% were Omega blocks, 20.8% were Cut-off low blocks, 16.7% were Rex blocks, and the percentage of the Cut-off high and Split flow blocks were 12.5% each. The results also indicated that the strongest blocking was the Omega blocking that occurred on 01-03 Feb 2006 and resulted in 120 mm rainfall.
近年来,由于大气阻塞对中纬度环流的影响,以及对寒流、热浪、干旱和暴雨等极端天气的影响,大气阻塞受到了很多关注。本文评估了大气阻塞对伊拉克天气事件的影响,特别是降雨。分析了2002年至2018年期间国家环境预测中心(NCEP)的每日气象数据,以确定伊拉克及其周边地区的不同大气阻塞系统。为了在地图上定位地块,根据平均海平面压力将研究区域从10-70°N和10-70°E扩展。本研究描述了2006年1月25日和2006年2月1日至3日发生的两例Omega阻塞系统。热带降雨测量任务(TRMM)观测到的降雨以及中分辨率成像光谱仪(MODIS)探测到的真彩色云图被用来确定与大气阻塞系统相关的暴雨的严重程度和轨迹。NCEP提供的数据空间分辨率为2.5 × 2.5, TRMM为0.25 × 0.25。对典型年份(2016年)的分析表明,在本工作期间检测到的24个阻塞系统中,Omega区块占37.5%,Cut-off low区块占20.8%,Rex区块占16.7%,Cut-off high区块和Split flow区块各占12.5%。结果还表明,2006年2月1日至3日发生的欧米茄阻塞是最强的阻塞,造成了120 mm的降雨。

The utilize of the web has made humans and companies powerless to exterior assaults. Indeed, cyber problems essentially influence information frameworks with distinctive types of malicious attacks such as spyware, virus, social engineering, etc. The Internet e-mail service, in particular, has become one of the most dependable methods of communication among people, institutions, and companies. The development of digital signatures to e-mail services has raised the e-mail security, which led to replacing the standard mailing of registered letters. Unfortunately, the process of sending and receiving e-mails has created a negative impact means on security and privacy from cybercriminals by diffusing spam and malware. As a result, e-mail hosts are constantly under attack by malicious programs that are often attached to e-mails. In this paper, the simulation model and prototype of an email traffic monitor developed and tested in order to prove the ability of our proposed method for detecting new viruses. This paper states the success possibility of this new method based on the simulation results. The results of the analysis suggest that the Cyber Security Modeling Language (CySeMoL) model has a good performance of operating system vulnerability prediction. At last, some useful suggestions in the context of the CySeMoL model are presented.
网络的使用使人类和公司对外部攻击无能为力。事实上,网络问题本质上是通过不同类型的恶意攻击(如间谍软件、病毒、社会工程等)影响信息框架。尤其是互联网电子邮件服务,已经成为人们、机构和公司之间最可靠的通信方式之一。电子邮件服务中数字签名的发展提高了电子邮件的安全性,从而取代了传统的挂号信邮寄方式。不幸的是,发送和接收电子邮件的过程通过传播垃圾邮件和恶意软件,对网络罪犯的安全和隐私造成了负面影响。因此,电子邮件主机经常受到附加在电子邮件中的恶意程序的攻击。本文开发并测试了电子邮件流量监视器的仿真模型和原型,以证明我们提出的方法检测新病毒的能力。根据仿真结果,阐述了该方法成功的可能性。分析结果表明,网络安全建模语言(cysyemol)模型具有较好的操作系统漏洞预测性能。最后,针对CySeMoL模型提出了一些有用的建议。
