...Show More Authors

تهدف هذه الدراسة إلى معرفة الفرق في التحصيل الدراسي في الكيمياء والاتجاه نحو العلوم بين طلاب التخصص العلمي وطلاب التخصص الصناعي الصف الأول كلية التربية ابن الهيثم، كذلك تهدف الدراسة إلى معرفة العلاقة بين التحصيل الدراسي في الكيمياء ودرجات اختبار نهاية الفصل في الكيمياء، والمعدل التراكمي بعد أخذ المقرر الدراسي والاتجاه نحو العلوم بالنسبة لطلاب التخصص العلمي وطلاب التخصص الصناعي.

لقد استخدمت الباحثة اختبار التحصيل في الكيمياء، وكذلك مقياس الاتجاه نحو العلوم لغرض هذه الدراسة، وقد تكونت عينة الدراسة من 36 طالباً من التخصص العلمي، وكذلك 36 طالباً من التخصص الصناعي.

وقد بيّنت نتائج الدراسة ما يلي:-

  • هناك فرق دال إحصائياً عند مستوى دلالة (0.05) بين طلاب التخصص العلمي وطلاب التخصص الصناعي في التحصيل الدراسي في الكيمياء لصالح طلاب التخصص الصناعي.
  • ليس هناك فرق دال إحصائياً في الاتجاه نحو العلوم بين طلاب التخصص العلمي وطلاب التخصص الصناعي.
  • هناك فرق دال إحصائياً عند مستوى دلالة (0.01) في درجات نهاية المقرر الدراسي في الكيمياء بين طلاب التخصص العلمي وطلاب التخصص الصناعي لصالح طلاب التخصص العلمي.
  • هناك معامل ارتباط دال إحصائياً عند مستوى دلالة (0.05) بين التحصيل في الكيمياء Gain Scores ودرجات اختبار نهاية المقرر الدراسي في الكيمياء بالنسبة لطلاب التخصص العلمي.
  • هناك معامل ارتباط دال إحصائياً عند مستوى دلالة (0.01) بين درجات نهاية المقرر الدراسي والمعدل التراكمي بالنسبة لطلاب التخصص العلمي.
  • هناك معامل ارتباط إحصائياً عند مستوى دلالة (0.01) بين المعدل التراكمي والاتجاه نحو العلوم بالنسبة لطلاب التخصص العلمي.
  • ليس هناك علاقة ارتباطية بين التحصيل الدراسي في الكيمياء والاتجاه نحو العلوم لطلاب التخصص العلمي.
  • ليس هناك أي علاقة ارتباطية بين التحصيل في الكيمياء ودرجات اختبار نهاية الفصل الدراسي والمعدل التراكمي والاتجاه نحو العلوم بالنسبة لطلاب التخصص الصناعي.

The Mutual Interaction effects between Array Antenna Parameters and Receiving Signals Bandwidth
...Show More Authors

The presence of a single complex adaptive weight in each element channel of an adaptive array antenna is sufficient for processing of narrowband signals. The ability of an adaptive array antenna to null interference deteriorates rapidly as the interference bandwidth increases. The performance of narrowband adaptive array antenna with LMCV Beamforming algorithm is examined. The interaction effects between received signal angle of arrival and array parameters like the interelement spacing and the number of array element and the received signal bandwidth were studied. The output Signal to Interference plus Noise Ratio (SINR) and Interference to Noise Ratio (INR) are used as performance parameters for evaluation of these effects. It is found

Teen-Computer Interaction: Building a Conceptual Model with Thoughts- Emotion-Behaviour
...Show More Authors

Teen-Computer Interaction (TeenCI) stands in an infant phase and emerging in positive path. Compared to Human-Computer Interaction (generally dedicated to adult) and Child-Computer Interaction, TeenCI gets less interest in terms of research efforts and publications. This has revealed extensive prospects for researchers to explore and contribute in the region of computer design and evaluation for teen, in specific. As a subclass of HCI and a complementary for CCI, TeenCI that tolerates teen group, should be taken significant concern in the sense of its context, nature, development, characteristics and architecture. This paper tends to discover teen’s emotion contribution as the first attempt towards building a conceptual model for TeenC

The research aims to test the effect of the behavioral factors (intangible) represented by an explanatory variable represented by organizational silence and a responsive variable of quality of Function life. The problem was the negative effects of the organizational silence on the morale of the employees and consequently their performance and the quality of function life. To collect the data and information needed to measure the two variables of research conducted in the health center / Sulaikh by taking a sample of (40) employees to test the hypotheses of research through the survey of their views, using statistical tools non parametric using the program. The most important recommendations were the establishment of training workshops fo

...Show More Authors

Abstract\

The developed financial infrastructure is one of the most important elements for achieving stable financial system in a country. The importance of developed financial infrastructure comes from its role in create economic and financial context attractive for foreign investments. Thus, this paper aims first to measure an index of financial infrastructure, and secondly, to gauge the nexus between the developed financial infrastructure and foreign investments inflow in Malaysia and Indonesia. We estimate the index of financial infrastructure by using different indicators such as (the institutional environment, access to finance, legal environment, and others).

By using the G

Performance Comparison of Different Advanced Control Schemes for Glucose Level Control under Disturbing Meal
...Show More Authors

Abstract

In this work, diabetic glucose concentration level control under disturbing meal has been controlled using two set of advanced controllers. The first set is sliding mode controllers (classical and integral) and the second set is represented by optimal LQR controllers (classical and Min-, ax). Due to their characteristic features of disturbance rejection, both integral sliding mode controller and LQR Minmax controller are dedicated here for comparison. The Bergman minimal mathematical model was used to represent the dynamic behavior of a diabetic patient’s blood glucose concentration to the insulin injection. Simulations based on Matlab/Simulink, were performed to verify the performance of each controll
