Abstract

This paper is about the preparations and methods used to teach, evaluate and test students without the use of papers in lectures or in mid and final exams for two classes: Computer Aided design CAD for third year students and Computer Aided Engineering CAE for fourth year students. Using both SolidWorks and ANSYS. This method was called paperless learning because computers are only being used for teaching and evaluating students and performing examinations. Students are involved interactively in the scientific material where this material is applied using computer programs which enable the student to perform simulations to solve all engineering problems. Also, students are given all electronic learning methods which are given in the first lecture and documented in discs, USB drives, and or external hard drives, these devices contain numerous eBooks, exercises, projects, educational films, and links and URLs for internet websites. This data is documented as Word documents or PDFs and students are free to copy and print any of these authorized materials to benefit from. Thus, the old-fashioned method of copying lectures on papers has been excluded so that the scientific material cannot be trapped within few exercises or fixed schedules during the academic year, but also given as electronic materials as mentioned earlier. This electronic material is being updated continuously along the academic year every year.

Abstract

In this study ,serum albumin level was determined in 61 blood samples using three different methods ,cellulose acetate electrophoresis (CAE), salt fractionation and bromocresolgreen(BCG) . The values of serum albumin (mean (95% confidence interval)) measured in gm/L by the above methods were 38.95 (1.64) , 38.13 (1.76) and 38.11 (1.8) respectively .There were no significant differences in the level of serum albumin determined by these methods (P≥0.05). Also, these methods showed statistically significant differences in the level of serum albumin determined by these methods (P≤ 0.001) ,As the BCG method give a relatively inaccurate albumin levels in abnormal sera therefore ,it is recommended that the BCG is to be used only as a screening method for serum albumin measurement for its simplicity and rapidity

في هذه الدراسة ,تم قياسمستوى الالبومين في الدم في 61 نموذج با ستخدام ثلاث طرق مختلفة الترحيل الكهربائي , الترسيب التجزيئي , وطريقة البروموكريسول كرين (BCG),وكانت قيمالالبومين]( 95%CL) X-[مقاسا ب غم/لترللطرق الثلاثة هي38.95(1.64),38.13(1.76))38.11(1.8) على التوالي .لم يكن هناك ةاختلاف احصائي مهم في مستوى الالبومين مقاسا بالطرق الثلاثة (0.05p≥). أظهرت الدراسة وجود ترابط موجب مهم احصائيا بين الطرق الثلاثة( 0.001P ≤) ونتيجة لكون طريقة(BCG) تعطي نتائج البومين غير دقيقة نسبيا في النماذج غيرالطبيعية, لذلك نوصي باستعمالها فقط كطريقة مسح لقياس مستوى الالبومين وذلك لبساطتها وسرعتها.

Abstract

Analytical formulations that is extremely important by understanding how can prepare the manufacturing process and the optimization of machining parameters such as cutting conditions, and tool geometries which is led to reduce the experimental tests needful. Finite element model belong numerical simulation method which is considered natural extension of analytical formulations as established a special relation to develop detailed of models during manufacturing process. It can provide detailed information from machining process that is depending on the cutting conditions such as cutting speed, chip formation, stress-strain analysis, and feed rate. The calibration procedure was carried out of finite element model and validation by comparing the experimental results and the corresponding numerical simulation data. The results indicate there is a good agreement between simulated values and experimental tests which depend to investigate on two types that is calibration and validation. This is because the validation of numerical simulation model and analytical formulations which is verified only when they have conform to experimental results. It concludes that the finite element model represents the real key to reduce the cost of manufacturing in terms of machining time saving and extend the duration of the cutting tool life.

الصيغ التحليلية التي هي في غاية الأهمية في فهم عملية التصنيع ولتحسين خواص معلمات القطع مثل ظروف و أداة القطع مما يؤدى إلى تقليل الاختبارات التجريبية المختبرية اللازمة. ان نمذجة العناصر تنتمي لطريقة المحاكاة العددية التي تعتبر امتدادا طبيعيا من الصيغ التحليلية وتؤسس لبناء علاقة خاصة لتطوير نماذج مفصلة و دقيقة خلال اجراء عملية التصنيع. ويمكن أن توفر معلومات مفصلة عن عملية القطع التي تعتمد على ظروف من اهمها سرعة القطع، وتشكيل الرقاقة، وتحليل الإجهاد والالتواء، ومعدل التغذية. نفذت عملية المعايرة ما بين نمذجة العناصر والتحقق من صحتها بمقارنة النتائج التجريبية المختبرية وبيانات المحاكاة العددية. تشير النتائج إلى وجود توافق جيد بين قيم المحاكاة والاختبارات التجريبية التي تعتمد على نوعين هما المعايرة والتحقق بينهما. ويرجع ذلك إلى ان التحقق من صحة نموذج المحاكاة العددية والتركيبات التحليلية التي تحققت قد اتفقت تماما مع النتائج التجريبية. ويستنتج من ذلك أن نمذجة العنصر يمثل المفتاح الحقيقي لخفض كلفة الانتاج من حيث توفير الوقت اللازم لعملية القطع واطالة عمر أداة القطع.
