The algorithm learns from a supervised and continuous input of large and new data sets unlike the standard programming, which requires clear step-by-step instructions. The aim of this study is to assess the ability of AI scanned mammograms to aid the ultrasound in the discrimination between phyllodes tumors and fibro-adenomas. Results This is a retrospective analysis included 374 proven phyllodes tumors (PT) and fibro-adenomas (FA). Digital mammogram and breast ultrasound was performed for all the cases and each breast was given a “Breast Imaging Reporting and Data System” (BI-RADS) score. Included mammograms were scanned by AI with resultant a qualitative heatmap and a quantitative abnormality scoring of suspicion percentage. The study included 164 PT (43.9%) and 2...

However, the visually impaired people may suffer from knowing each currency paper apart. Currency Recognition Systems (CRS) can be used to help blind and visually impaired people who suffer from monetary transactions. In this paper, a Currency Recognition System based on Oriented FAST and rotated BRIEF (ORB) algorithm is proposed. The ORB is based on the FAST detector and the visual descriptor BRIEF (Binary Robust Independent Elementary Features). Its aim is to provide a fast and efficient alternative to Local ScaleInvariant Features (SIFT). The proposed system is applied to Egyptian paper currencies including six kinds of currency papers. Initially, some pre-processing operations are performed on a given currency paper input image. Then, important ROI is extracted from the background. The ORB Algorithm is...

Being called growth, deviation or expansions reflects the same sense ensuring that a city is never in a stagnant state. This was the main reason behind having the government of Egypt represented in the Ministry of Housing, Utilities and Urban Development and specifically the New Urban communities Authority- prepare updated periodical strategic plans for the new Egyptian cities to feedback cities problems, potentials and constrain defining new visions and objectives within the comprehensive plan for the country. When the studies for the updated strategic plan for 6th of October city started in 2007, obvious deviations of its executive plans from the original city’s goals and objectives were noticed. These unplanned extensions resulted in random urban growth and land uses changes that lead to the lack of a comprehensive city vision and the creation of an urban environment that lacks identity and cohesiveness with ...

Transsphenoidal approach is now the gold standard for treatment of PAs either microscopic or endoscopic. Aim of the Work to analyze the collective outcomes from studies comparing the microscopic transsphenoidal surgery (MTS) with the endoscopic transsphenoidal surgery (ETS) regarding gross total resection (GTR) and postoperative cerebrospinal fluid (CSF) leak. Patients and Methods we searched PubMed, Google scholar search engine, Cochrane database of systematic reviews, EMBASE and science Direct, using the following keywords “Pituitary adenoma/tumor, endoscopy or endoscopic, microscopy or microscopic, gross total/subtotal/near total/radicular resection/excision, hypophysectomy, debulking, CSF leak/leakage ". The mentioned databases were searched for studies published during period from the 1st of Jan 2015 to 31 Aug. 2020. Results Total number of patients in inclu...

It can move intelligently in a given environment trying to find a certain goal of interest using this goal's relations with other objects in the environment.
