هدف البحث الى اعداد بيئة تعليمية افتراضية بالميتافيرس باستخدام تطبيق HomeCourt.والتعرف على اثر بيئة افتراضية بالميتافيرس باستخدام تطبيق HomeCourt في تعلم بعض المهارات الاساسية بكرة السلة للطالبات. استخدمت الباحثة المنهج التجريبي بالمجموعتين المتكافئتين بالاختبار القبلي والبعدي, " لأنه يعد أكثر الوسائل كفاية في الوصول إلى معرفة موثوق بها .واعتمدت الباحثة تصميم مجموعتين متساويتين مستقلتين (تجريبية وضابطة ) . اما مجتمع البحث وعينته تحدد مجتمع البحث بطالبات المرحلة الثانية , قسم التربية البدنية وعلوم الرياضة في كلية التربية الأساسية -الجامعة المستنصرية , للعام الدراسي (2024-2025) والبالغ عددهن (30) طالبة وقد تم اختيار ( 24) طالبة منهن كعينة للبحث وذلك بسبب استبعدا 6 لاعبات كونهن ممارسة للعبة في الأندية الرياضية , وبذلك شكلت العينة نسبة مئوية مقدارها (80%) وبذلك تكون العينة مثلت المجتمع الأصلي تمثيلا صادقا, وقد تم تقسيم العينة بالطريقة العشوائية المنتظمة (القرعة ) على مجموعتين الاولى ضابطة وبلغ عددها (12) طالبة, والثانية تجريبية وبلغ عددها ( 12) طالبة أيضا . عمدت الباحثة الى تحديد المهارات واختبارتها وبعدها اعتد الباحثة الاختبار القبلي وصممت بعدها بيئة تعليمية افتراضية بالميتافيرس وفق تطبيق بيئة افتراضية بالميتافيرس باستخدام تطبيق HomeCourt واستخدمت الباحثة الحقيبة الإحصائية spss وتوصلت الباحثة الى نتائج علمية اوصلتها الى اهم الاستنتاجات منها المواقف الافتراضية التي يوفرها HomeCourt تسهم في تعزيز الدقة في التصويب والتمرير من خلال تكرار التمارين وتقديم تغذية راجعة فورية، ما ينعكس إيجاباً على التفاعل بالاداء المهاري ، ومن اهم التوصيات تصميم مناهج تتعليمية مدمجة تجمع بين الواقع الافتراضي والواقع الملموس وفق الميتافيرس باستخدام تطبيق HomeCourt، مع مهارات مماثلة في ملعب حقيقي مع إشراف مدرب يطبق ما تم تعلُّمه افتراضياً.
Czerwi’nski et al. introduced Lucky labeling in 2009 and Akbari et al and A.Nellai Murugan et al studied it further. Czerwi’nski defined Lucky Number of graph as follows: A labeling of vertices of a graph G is called a Lucky labeling if for every pair of adjacent vertices u and v in G where . A graph G may admit any number of lucky labelings. The least integer k for which a graph G has a lucky labeling from the set 1, 2, k is the lucky number of G denoted by η(G). This paper aims to determine the lucky number of Complete graph Kn, Complete bipartite graph Km,n and Complete tripartite graph Kl,m,n. It has also been studied how the lucky number changes whi

Because of the experience of the mixture problem of high correlation and the existence of linear MultiCollinearity between the explanatory variables, because of the constraint of the unit and the interactions between them in the model, which increases the existence of links between the explanatory variables and this is illustrated by the variance inflation vector (VIF), L-Pseudo component to reduce the bond between the components of the mixture.
To estimate the parameters of the mixture model, we used in our research the use of methods that increase bias and reduce variance, such as the Ridge Regression Method and the Least Absolute Shrinkage and Selection Operator (LASSO) method a
... Show MoreThis paper describes a number of new interleaving strategies based on the golden section. The new interleavers are called golden relative prime interleavers, golden interleavers, and dithered golden interleavers. The latter two approaches involve sorting a real-valued vector derived from the golden section. Random and so-called “spread” interleavers are also considered. Turbo-code performance results are presented and compared for the various interleaving strategies. Of the interleavers considered, the dithered golden interleaver typically provides the best performance, especially for low code rates and large block sizes. The golden relative prime interleaver is shown to work surprisingly well for high puncture rates. These interleav
... Show MoreThis study had succeeded in producing a new graphical representation of James abacus called nested chain abacus. Nested chain abacus provides a unique mathematical expression to encode each tile (image) using a partition theory where each form or shape of tile will be associated with exactly one partition.Furthermore, an algorithm of nested chain abacus movement will be constructed, which can be applied in tiling theory.
In the last years, new non-invasively laser methods were used to detect breast tumors for pre- and postmenopausal females. The methods based on using laser radiation are safer than the other daily used methods for breast tumor detection like X-ray mammography, CT-scanner, and nuclear medicine.
One of these new methods is called FDPM (Frequency Domain Photon Migration). It is based on the modulation of laser beam by variable frequency sinusoidal waves. The modulated laser radiations illuminate the breast tissue and received from opposite side.
In this paper the amplitude and the phase shift of the received signal were calculated according to the orig
