This research aims toknow the learning styles according to the model of Felder and Silverman and its relationship to effectively self- perceived mathematicalamong students of the Faculty of Education Pure Sciences - Ibn al-Haytham. By answering the following questions: 1. What are the preferred methods of learning among students in the mathematics department according to the model Felder and Silverman? 2. What is the mathematicalself-perceived levelof the students at the Department of Mathematics effectiveness level? 3. What is the relationship between learning styles according to the Felder model and Silverman and the effectiveness of mathematical self-perceived of the students of the Department of Mathematics? The research sample consisted of 80 male and female students from the fourth grade students in the Department of Mathematics in the College of Education Pure Sciences - Ibn al-Haytham for the academic year 2015/2016. As for the two tools the first search tools is a measure of learning methods developed by (Felder and Silverman, 1988) Translation (Al-Zubaidi, 2015) which consisted of 44 items distributed on four areas: (practical - Contemplative) - (sensory - intuitive) - (optical -pronunciation) - (sequential - total).And the second tool and is a measure of the effectiveness of sports self-perceived, which consists of a paragraph (30), were reliability and validity account and conducted statistical analyzes to calculate the difficulty and ease transactions. After the use of appropriate statistical methods to analyze the results, the results indicated that (1) 37.5% of the students have more than one level indicating no preference for any style of learning. (2) 30% of the students' own (visual - verbal)method (3) 16.25% of the students' own (sensory - intuitive)method. (4) 11.25% of the students' own (sequential - total)method. (5) 5% of the students' own (practical - Contemplative)method. (6) Students did not prefer any of the styles (intuitive - verbal - total). (7) the students in grade IV Department of Mathematics in the College of Education Pure Sciences / Ibn alHaytham students have aware of the effectiveness of mathmatics. (8) There is no relationship between the learning styles according to the model Felder and Silverman and the effectiveness of sports self-conscious of the students of the Department of Mathematics Therefore, the researcher recommends that students should be aware of the methods and activities that are compatible with their learning methods, as well as the development of their perceived mathematical effectiveness to enhance their ability to solve any mathematical task, no matter how difficult and flexible it may be.In the light of the results of the research, a number of proposals were developed.
This paper aims to propose a hybrid approach of two powerful methods, namely the differential transform and finite difference methods, to obtain the solution of the coupled Whitham-Broer-Kaup-Like equations which arises in shallow-water wave theory. The capability of the method to such problems is verified by taking different parameters and initial conditions. The numerical simulations are depicted in 2D and 3D graphs. It is shown that the used approach returns accurate solutions for this type of problems in comparison with the analytic ones.

In this research, the influence of the orientation and distance factors on the lowest usable frequency (LUF) parameter has been studied theoretically. The calculations of the (LUF) parameter have been made using the (VOACAP) international communication model for the connection links between the capital Baghdad and many other locations that distributed on different distances and directions over the Middle East region. The results shown in this study indicate there is a slight affection of the link direction (orientation) on the LUF parameter, while the influence of the distance factor is more significant on the values of the LUF parameter. The day/night effect appears for the long distance HF links (i.e. more than a 500 Km)
A tunable band pass filter based on fiber Bragg grating sensor using an in-fiber Mach-Zender interferometer with dual micro-cavities is presented. The micro-cavity was formed by splicing together a conventional single-mode fiber and a solid core photonic crystal fiber (SCPCF) with simple arc discharge technique. Different parameters such as arc power, length of the SCPCF and the overlap gap between samples were considered to control the fabrication process. The ellipsoidal air-cavity between the two fibers forms Fabry-Perot cavity. The diffraction loss was very low due to short cavity length. Ellipsoidal shape micro-cavities were experimentally achieved parallel to the propagation axis having dimensions of (24.92 – 62.32) μm of width

Although tattooed literary characters are not new in literature, they are still in children’s literature. Inked characters were nearly absent from children’s books and with the dawn of the twenty first century many of them portrayed tattooed characters. The problem of the study lies in the lack of studies concerning these types of characters in children’s books. The researchers aim to study inked characters in selected stories for children to show the different literary uses of tattoos in these stories, serving not only characterization but theme and symbolism as well. Two children's stories are selected for this study: Tell Me A Tattoo Story (2016) by Alison McGhee and My Teacher Has Tattoos (2023) by Darren Lopez. The researchers st
