Unconstrained Iris Recognition
This research focuses on iris recognition, the most accurate form of biometric identification. The robustness of iris recognition comes from the unique characteristics of the human, and the permanency of the iris texture as it is stable over human life, and the environmental effects cannot easily alter its shape.
In most iris recognition systems, ideal image acquisition conditions are assumed. These conditions include a near infrared (NIR) light source to reveal the clear iris texture as well as look and stare constraints and close distance from the capturing device. However, the recognition accuracy of the-state-of-the-art systems decreases significantly when these constraints are relaxed. Recent advances have proposed different methods to process iris images captured in unconstrained environments. While these methods improve the accuracy of the original iris recognition system, they still have segmentation and feature selection problems, which results in high FRR (False Rejection Rate) and FAR (False Acceptance Rate) or in recognition failure.
In the first part of this thesis, a novel segmentation algorithm for detecting the limbus and pupillary boundaries of human iris images with a quality assessment process is proposed. The algorithm first searches over the HSV colour space to detect the local maxima sclera region as it is the most easily distinguishable part of the human eye. The parameters from this stage are then used for eye area detection, upper/lower eyelid isolation and for rotation angle correction. The second step is the iris image quality assessment process, as the iris images captured under unconstrained conditions have heterogeneous characteristics.
In addition, the probability of getting a mis-segmented sclera portion around the outer ring of the iris is very high, especially in the presence of reflection caused by a visible wavelength light source. Therefore, quality assessment procedures are applied for the classification of images from the first step into seven different categories based on the average of their RGB colour intensity. An appropriate filter is applied based on the detected quality.
In the third step, a binarization process is applied to the detected eye portion from the first step for detecting the iris outer ring based on a threshold value defined on the basis of image quality from the second step. Finally, for the pupil area segmentation, the method searches over the HSV colour space for local minima pixels, as the pupil contains the darkest pixels in the human eye.
In the second part, a novel discriminating feature extraction and selection based on the Curvelet transform are introduced. Most of the state-of-the-art iris recognition systems use the textural features extracted from the iris images. While these fine tiny features are very robust when extracted from high resolution clear images captured at very close distances, they show major weaknesses when extracted from degraded images captured over long distances. The use of the Curvelet transform to extract 2D geometrical features (curves and edges) from the degraded iris images addresses the weakness of 1D texture features extracted by the classical methods based on textural analysis wavelet transform. Our experiments show significant improvements in the segmentation and recognition accuracy when compared to the-state-of-the-art results
The Effectiveness of Using the Internet of Things in Developing Scientific Concepts for the Sixth Basic Grade Students in Mathematics and their Attitudes Towards the Internet of Things فاعلية استخدام إنترنت الأشياء في تنمية المفاهيم العلمية لدى طلبة الصف السادس الأساسي في مادة الرياضيات واتجاهاتهم نحو إنترنت الأشياء
Abstract:
This study aimed to show the effect of using the internet of things (IoT) in developing scientific concepts for sixth grade in basic mathematics and their attitudes towards the internet of things. the study sample consisted of (60) male and female students from the sixth basic class in Mayar international schools of the Directorate of Special Education in the Capital Governorate in Jordan, during the second semester of the academic year 2019/2020. Two classes were chosen and randomly divided into two groups, one experimental consisting of (30) male and female students who studied using the internet of things, and the other consisted of (30) male and female students studied in the traditional method. To achieve the objective of the study, the internet of things application was prepared, and the development of scientific concepts was tested. The results of the study indicated the presence of statistically significant differences between the mean of students ’scores at the level of significance (α = 0.05) in the experimental and control groups in the post-test and in favor of the experimental group, while the results showed that there were no statistically significant differences due to the difference in gender, and also showed that there was a difference statistically significant between the pre- and post-tests at the significance level (α = 0.05). The differences came in favor of the post-test for the experimental group students. The study recommended that attention be paid to providing internet applications of things in teaching various subjects, in the basic stage.

On Teaching Future Time to EFL Learners: Problems and Solutions
This study in all its overall presentation seeks to give a comprehensive account of the difficulties involved in teaching future time to students who learn English as a foreign language; and the (pedagogical) solutions humbly suggested for learners, teachers, text-book writers, linguists and psychologists since they are expected to be the best who can deal with the problems that impede the acquisition of the foreign language concepts. The work like many language teachers' works is a reaction to the frustrating state of the students who cannot use their knowledge in a real communicative situation. It spotlights the reasons of students' inefficient use of the English future structures; and projects, through a questionnaire, the most possible reasons of this problem propounding some useful techniques to overcome the problem depending on what is written in the literature of language learning and teaching. The study tackles the topic of tense and time as an entrance to investigate the nature of future structures. Apart from presenting a pedagogical view of future time references, it provides almost all the constructions used to express futurity and the indications they refer to getting use of the idea of Fleischman's time-line. The study ends with many results, findings and pedagogical suggestions.Keyword: Futurity, Pedagogy and pedagogical grammar, EFL acquisition, Tense and time, Time-Lin
Determination of optimum plant density for faba bean (Vicia faba L.) on vertisols at Haramaya, Eastern Ethiopia
Optimum inter-row spacing and seeding rate of sesame for harnessing the maximum productivity potential in the dry land area of Abergelle District, Northeast Ethiopia
The onset of faba bean farming in the Southern Levant
Even though the faba bean (Vicia faba L.) is among the most ubiquitously cultivated crops, very little is known about its origins. Here, we report discoveries of charred faba beans from three adjacent Neolithic sites in the lower Galilee region, in the southern Levant, that offer new insights into the early history of this species. Biometric measurements, radiocarbon dating and stable carbon isotope analyses of the archaeological remains, supported by experiments on modern material, date the earliest farming of this crop to ~10,200 cal BP. The large quantity of faba beans found in these adjacent sites indicates intensive production of faba beans in the region that can only have been achieved by planting non-dormant seeds. Selection of mutant-non-dormant stock suggests that the domestication of the crop occurred as early as the 11(th) millennium cal BP.
