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.","PeriodicalId":7515,"journal":{"name":"Al-Mustansiriyah Journal of Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73448654","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}

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.","PeriodicalId":7515,"journal":{"name":"Al-Mustansiriyah Journal of Sciences","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2020-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75308061","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 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.
