اثر استخدام المختبر العلمي
...Show More Authors

أن التقدم والتطور العلمي اللذين حدثا خلال القرن العشرين كان لهما اثر كبير في المسيرة العلمية ، حيث أن من المفترض على أفراد مجتمع المتعلمين أن يتزودوا بمهارات التفكير العلمي لكي تمكنهم من العيش في العصر الحالي وليشاركوا فيه بذكاء وفاعلية حتى يحققوا لذاتهم ملائمة أفضل مع التغييرات والتطورات المختلفة التي حدثت في العالم لذا فان طرائق التدريس أصبحت حاجة ملحة لا تقل أهميتها عن المدرس والمادة الدراسية حيث أكدت جميع المؤتمرات والندوات إتباع طرائق التدريس الحديثة ورفع الكفاية التعليمية للمتعلم فكانت طريقة الاستكشاف من بين هذه الطرائق التي يكشف بواسطتها الطالب الأشياء بنفسه ويوضح المكثف الأول وليجد بنفسه سبيله إلى المعرفة . ويهدف البحث الى معرفة اثر استخدام المختبر الاستكشافي في التفكير العلمي لدى طلبة معهد الطب التقني في مادة الإحياء المهجرية من خلال التحقق من الفرضية الصفرية لا يوجد فرق ذو دلالة إحصائية بين متوسط درجات التفكير العلمي المجموعة التجريبية التي تستخدم الطريقة الاستكشافية والمجموعة الضابطة التي تستخدم المختبر التقليدي ، ثم استخدام التصميم التجريبي ذات الاختبار ألبعدي حيث تحدد البحث الحالي بطلبة معهد الطب التقني للعام الدراسي 2007- 2008 حيث اختيرت الشعبتين أ- ب عشوائياً ، اذ  بلغ عدد العينة (62) طالباً وطالبة وبواقع (32) طالب وطالبة للمجموعة التجريبية اما المجموعة الضابطة فعددها (30) طالب وطالبة وكوفئت في متغيرات ( العمر ، التحصيل الدراسي السابق لمادة الأحياء ، الذكاء ) وتم تحقيق من معامل الصعوبة والسهولة والقوة التميزية وحساب معامل الثبات باستخدام  معادلة كودرريتشاردسون  حيث بلغ عدد الثبات (87، 0 ) للفقرات الموضوعة في الاختبار ، حيث أظهرت النتائج تفوق المجموعة التجريبية التي درست مادة الإحياء المهجرية وفق الطريقة الاستكشافية على المجموعة الضابطة حيث ان استخدام الطريقة الاستكشافية تؤدي الى تنمية مهارات التفكير العلمي وتقترح الباحثة أجراء دراسة تتناول اثر استخدام المختبر الاستكشافي بمتغيرات أخرى مثل تنمية التفكير ألابتكاري وتنمية التفكير الناقد .

Reconstruction of Three-Dimensional Object from Two-Dimensional Images by Utilizing Distance Regularized Level Algorithm and Mesh Object Generation
...Show More Authors

Three-dimensional (3D) reconstruction from images is a most beneficial method of object regeneration by using a photo-realistic way that can be used in many fields. For industrial fields, it can be used to visualize the cracks within alloys or walls. In medical fields, it has been used as 3D scanner to reconstruct some human organs such as internal nose for plastic surgery or to reconstruct ear canal for fabricating a hearing aid device, and others. These applications need high accuracy details and measurement that represent the main issue which should be taken in consideration, also the other issues are cost, movability, and ease of use which should be taken into consideration. This work has presented an approach for design and construc

استخدام المحاكاة للمفاضلة بين بعض الطرائق الحديثة لنموذج GM(1,1) لايجاد القيم المفقودة و تقدير المعلمات مع تطبيق عملي
...Show More Authors

The grey system model GM(1,1) is the model of the prediction of the time series and the basis of the grey theory. This research presents the methods for estimating parameters of the grey model GM(1,1) is the accumulative method (ACC), the exponential method (EXP), modified exponential method (Mod EXP) and the Particle Swarm Optimization method (PSO). These methods were compared based on the Mean square error (MSE) and the Mean Absolute percentage error (MAPE) as a basis comparator and the simulation method was adopted for the best of the four methods, The best method was obtained and then applied to real data. This data represents the consumption rate of two types of oils a heavy fuel (HFO) and diesel fuel (D.O) and the use of tests to conf
