Recognize Arabic Handwritten using CNN Model

احد أكثر التحديات التي تواجه التعلم الآلي هو التعرف على الكتابة بخط اليد ، وخاصة النصوص العربية ، لأن  هناك العديد من أساليب الكتابة للخط العربي. في هذه الورقة ، يُقترح نموذج تحقيق لتمييز النصوص العربية المكتوبة بخط اليد باستخدام الشبكة العصبية التلافيفية (CNN)، مع طبقات متعددة من التطبيع والتنظيم لتقليل وقت التدريب وزيادة الدقة الإجمالية ، تم الوصول الى  دقة تحقق 98 ٪ لمجموعة بيانات Kaggle للغة العربية حيث استخدمت أحرف وأرقام مكتوبة بخط اليد باستخدام Python.One of the most challenges that face machine learning is handwritten recognition, especially Arabic scripts, because many styles found for Arabic font. In this paper, an investigation model is proposed to make recognition for Arabic handwritten scripts utilizing Convolutional Neural Network (CNN), with multi layers of Normalization and Regularization to reduce training time and increase overall accuracy, with validation accuracy 98% for Kaggle dataset for Arabic handwritten characters and digits using Python

Real Time Blind People Assistive System Based on OpenCV

النظام المقترح مفيد للغاية للمكفوفين، حيث يعطي النظام فكرة عن الحاضرين في محيط المكفوفين، لذا فإن النظام المساعدالمقترح يعتمد على الرازبيري pi3 لإبلاغ المكفوفين عن عدد الأشخاص الموجودين حولهم. يركز هذا العمل على اكتشاف مميزات الوجه بناءً على خوارزمية Haar المتتالية وOpenCV باستخدام لغة البرمجة بايثون. تم الحصول على نتائج مرضية جدا عند التعامل مع حالات مختلفة بدقة عالية ووقت معالجة قصير، وبالتالي تقلل OpenCV من تأخير الحصول على النتائج، وتزيد خوارزمية سلسلة Haar من الدقة.The proposed system is very helpful for blind people, in term of taking an idea about the attendance person/s in their environment simultaneously, so an assistive system based on raspberry pi3 is developed to inform the blind how many persons are around. This work focuses on face detection based on Haar cascade algorithm and OpenCV using python. Satisfied results with different cases are obtained with high accuracy and short processing time, hence OpenCV reduce the delay for getting output, and Haar cascade algorithm increases the accuracy, the system is portable and very light to carry

Prevalence of vitamin D level in the serum of patients living in Erbil city, Iraq, referred to private clinical laboratory and effect of age and sex on it

This retrospective study aimed to determine the levels of 25- hydroxyvitamin D [25-(OH) D] in the individuals that have been referred to two laboratories (Bio Lab and King Lab) and to around 50 private side laboratories that use both Bio Lab and King Lab as a referral lab for their tests, in Erbil city, Iraq. Then show the range of deficiency and its relation with sunlight exposure, sex and age. Out of the total number of cases (N=10823), large percentage (nearly 78%) referred to both clinical laboratory based in Erbil city were found to have a deficiency in vitamin D levels, which means they had 25-(OH) D levels lower than 20 μg/L. This study found the percentage of vitamin D level in the serum of groups insufficient, deficient, adequate, optimal; intoxication were 52.8, 24.1, 11, 12 and 0.2% respectively. When the records have been compared according to gender, the results suggested that there was no difference between male and female within the study population (P>0.05), while there was difference in the grouped ages (P<0.05). Our results indicate that although Erbil is located in a Mediterranean country, people living there should periodically check their 25-(OH) D levels, in order to get appropriate supplements of vitamin D, which eventually prevents secondary chronic disease due to vitamin D deficiency

Advances in laparoscopic urologic surgery techniques [version 1; referees: 3 approved]

The last two decades witnessed the inception and exponential implementation of key technological advancements in laparoscopic urology. While some of these technologies thrived and became part of daily practice, others are still hindered by major challenges. This review was conducted through a comprehensive literature search in order to highlight some of the most promising technologies in laparoscopic visualization, augmented reality, and insufflation. Additionally, this review will provide an update regarding the current status of single-site and natural orifice surgery in urology

Critical Review Of \u27Pentafecta\u27 Outcomes After Robot-Assisted Laparoscopic Prostatectomy In High-Volume Centres

Historically, the ideal outcome of radical prostatectomy (RP) has been measured by achievement of the so-called \u27trifecta\u27, or the concurrent attainment of continence and potency with no evidence of biochemical recurrence. However, in the PSA era, younger and healthier men are more frequently diagnosed with prostate cancer. Such patients have higher expectations from the advanced minimally invasive surgical technologies. Mere trifecta is no longer an ideal outcome measure to meet the demands of such patients. Keeping the limitations of trifecta in mind, we have earlier proposed a new method of outcomes analysis, called the \u27pentafecta\u27, which adds early complications and positive surgical margins (PSMs) to trifecta. We performed a Medline search for articles reporting the complications, PSM rates, continence, potency and biochemical recurrence after robot-assisted RP. Related articles were selected and individual outcomes were reviewed. © 2011 BJU INTERNATIONAL

Employing Sisko non-Newtonian model to investigate the thermal behavior of blood flow in a stenosis artery: Effects of heat flux, different severities of stenosis, and different radii of the artery

In this paper, a numerical investigation is carried out to study the blood flow behavior within the stenosis artery. An artery is under applying a constant heat flux on the boundary walls in this simulation. Lumen model is employed for simulation of the artery and the Sisko model is used to indicate properties of blood as non-Newtonian fluid. Also, the cone geometry of stenosis with different severities and radii are simulated. Then, effects of heat flux, different severities of stenosis, and different radii of the artery are studied on the blood flow behavior. It is reported that before stenosis, velocity is increasing and heat transfer rate is also increasing which cause temperature to be decreased in stenosis position. But after stenosis, velocity is decreased. Consequently, heat transfer rate is decreased which leads to reduction in blood temperature. Also, since the blood particles adhere to the arterial wall, with increasing radial distance from the walls, velocity is increased, which causes maximum velocity to be found in the central region. Moreover, the thermal driving force is damped in the lateral region of the artery and does not affect velocity. On the other side, as the severity increases step by step, the temperature decreases, respectively. In fact, the cross-sectional area decreases with increasing severity of stenosis. Consequently, velocity increases and causes heat transfer enhancement, which leads to a reduction in blood temperature. Therefore, the highest temperatures are related to the artery with an intensity of 20%. Although the cross-section area of the artery can change blood temperature, but its role can be ignorable in temperature enhancement and body healthy in this regard
