التعلم التعاوني وأثره على التحصيل والاتجاه نحو الحاسب الآلي عند طلبة كلية التربية بجامعة بغداد
...Show More Authors

هدفت هذه الدراسة إلى مقارنة أثر أسلوب التعلم التعاوني بالأسلوب التقليدي في التحصيل الدراسي، وعلاقته بالاتجاه نحو الحاسب الآلي عند طلبة كلية التربية بجامعة بغداد خلال دراستهم لمقرر الحاسب الآلي وقد تضمنت إجراءات الدراسة استخدام الأسلوب التجريبي، وذلك بتوزيع أربع شعب دراسية على مجموعتين: "مجموعة تجريبية" يتم تدريسها باستخدام أسلوب التعلم التعاوني، والمجموعة الثانية: "مجموعة ضابطة" يتم تدريسها بالطريقة التقليدية. وقد استخدم في هذه الدراسة مقياسان: الأول اختبار لقياس التحصيل الدراسي، والآخر استبانة لقياس الاتجاه نحو الحاسب الآلي. وقد تضمنت استبانة الاتجاه أربعة محاور، هي: الرأي تجاه الحاسب، القلق من الحاسب، والوعي بأهمية الحاسب، والخوف من دراسة المقرر. وقد تم تطبيق المقياسين مرتين: الأولى في بداية الفصل الدراسي، والذي نتج عنه عدم وجود فروق ذات دلالة إحصائية بين الطلبة سواء في معلوماتهن عن الحاسب، أو في اتجاههن نحوه، أو في خوفهن من دراسة مقرر الحاسب الآلي، ولكن ظهر تخوف كبير من قبل أغلبية أفراد العينة في محور الخوف من دراسة المقرر. أما التطبيق الثاني فكان في نهاية الفصل الدراسي، وأظهرت النتائج وجود فروق ذات دلالة إحصائية في كل من مستوى تحصيل الطلبة، وفي الثلاثة محاور الأولى من مقياس الاتجاه نحو الحاسب وذلك لصالح المجموعة التجريبية. أما المحور الرابع "الخوف من دراسة المقرر" فلم يظهر فرق ذو دلالة إحصائية بين المجموعتين يمكن إرجاعه إلى أسلوب التعلم، غير أن الفرق ظهر في ارتفاع متوسط الدرجات لأغلب أفراد العينة ما بين بداية الفصل الدراسي ونهايته، الأمر الذي أكد على أن مجرد تعلم الحاسب بغض النظر – عن الطريقة المتبعة – ساعد في تقليل الخوف من الدراسة عن الحاسب الآلي. أما الأسلوب التعاوني فكان عاملاً مساعداً في زيادة التحصيل الدراسي وبناء اتجاه جيد نحو الحاسب الآلي.

Taxonomy of Memory Usage in Swarm Intelligence-Based Metaheuristics
...Show More Authors

Metaheuristics under the swarm intelligence (SI) class have proven to be efficient and have become popular methods for solving different optimization problems. Based on the usage of memory, metaheuristics can be classified into algorithms with memory and without memory (memory-less). The absence of memory in some metaheuristics will lead to the loss of the information gained in previous iterations. The metaheuristics tend to divert from promising areas of solutions search spaces which will lead to non-optimal solutions. This paper aims to review memory usage and its effect on the performance of the main SI-based metaheuristics. Investigation has been performed on SI metaheuristics, memory usage and memory-less metaheuristics, memory char

PROTOTYPING TO DESIGN AN ANAGLYPH 3D IMAGE BASED ON WATERFALL MODEL
...Show More Authors

In this paper, a discussion of the principles of stereoscopy is presented, and the phases
of 3D image production of which is based on the Waterfall model. Also, the results are based
on one of the 3D technology which is Anaglyph and it's known to be of two colors (red and
cyan).
A 3D anaglyph image and visualization technologies will appear as a threedimensional
by using a classes (red/cyan) as considered part of other technologies used and
implemented for production of 3D videos (movies). And by using model to produce a
software to process anaglyph video, comes very important; for that, our proposed work is
implemented an anaglyph in Waterfall model to produced a 3D image which extracted from a
video.

Effects of Different Types of Fillers on Dry Wear Characteristics of Carbon-Epoxy Composite
...Show More Authors

Experimental investigations had been done in this research to demonstrate the effect of carbon fiber and Ceramic fillers contents on the tribological behaviour of (15% volume fraction) carbon-epoxy composite system under varying volume fraction, load, time and sliding distance. The wear resistance were investigated according to ASTM G99-05standard using pin on disc machine to present the composite tribological behaviour. The influence of three ceramic fillers, granite, perlite and calcium carbonate (CaCO3), on the wear of the carbon fabric reinforced epoxy composites under dry sliding conditions has been investigated. The effect of variants in volume fraction, applied load, time and sliding distance on the wear behaviour of po

Influence of Optical Fiber Diameters on the Performance of Surface Plasmon Resonance Sensor
...Show More Authors

In this research, a sensor for chemical solutions was designed and formed using optical fiber-based on a surface Plasmon resonance technology. A single-mode optical fiber with three different diameters (25, 45 and 65) µm was used, respectively.  The second layer of the low refractive fiber was replaced by gold, which was electrically deposited at 40 µm thickness. For each of the three types of optical fiber, different saline concentrations (different index of refraction) were used to evaluate the performance of the refractive index sensor (chemical sensor) by measuring its sensitivity and resolutions. The highest values we could get for these two parameters were 240mm/RIU, and 6*10-5 RIU respectively, when the diameter of a

That the structural changes in the environment, business and finance and the spread of business and the diversity of transactions between economic organizations and breadth of a commercial scale in the world have left their clear on the need to keep up with the accounting for these variables as one of the social sciences affect and are affected by the surrounding environment because of the various economic and social factors, technical, legal and others.

As a result of these variables emerged a new field of accounting called Forensic Accounting, which involves the use of expertise of multiple pour in the end to the accounting profession, where the Forensic Accounting cover a large area of ​​disciplines including strengthening
