Studies on Dialectical Arabic are growing more important by the day as it becomes the primary written and spoken form of Arabic online in informal settings. Among the important problems that should be explored is that of dialect identification. This paper reports different techniques that can be applied towards such goal and reports their performance on the Multi Arabic Dialect Applications and Resources (MADAR) Arabic Dialect Corpora. Our results show that improving on traditional systems using frequency based features and non deep learning classifiers is a challenging task. We propose different models based on different word and document representations. Our top model is able to achieve an F1 macro averaged score of 65.66 on MADAR's smallscale parallel corpus of 25 dialects and Modern Standard Arabic (MSA).

Introduction: Throughout the entire female reproductive lifespan, the ovary relies on the reserve of resting follicles or 'ovarian reserve' which is a measure of ovarian ageing. It is defined by the quantity and quality of the remaining primordial follicular pool within the paired ovaries at any given time. Aim of the Work: The aim of our study is to compare 2D ultrasound imaging with 3D ultrasound imaging for assessment of ovarian function in infertile female. Patients and Methods: This Observational prospective study was done in the department of Obstetrics and Gynecology Minia maternity university hospital in the period of February 2018 to July 2018. This study was approved by the local ethical committee of research department of Obstetrics & Gynecology, Minia University. Results: The collected data used for comparison between use of two dimension and three dimension ultrasound for evaluation of ovaries of infertile patients -including patient's characteristics, fertility data and 2D & 3D measurements -were tabulated and shown infigures. Conclusions and Recommendations: Three-dimensional ultrasonography is an imaging modality that can be used as a complementary method for other endocrine markers for the assessment of ovarian reserve. It allows excellent evaluation of the ovaries with direct quantitative estimation of antral follicle count, ovarian volume and with power Doppler. Using 3D software including sonoAVC™ and VOCAL™ programs can increase accuracy and efficacy of ovarian evaluation. Patient examination with 3D ultrasound is less time consuming and less patient discomfort.
