إن النجاح في أداء المتطلبات الفنية والخططية في أي من الألعاب ألرياضيه يستوجب امتلاك العناصر الاساسيه المتعلقة بطبيعة الاداء ونوع الفعالية الرياضية الممارسة , لذا فان اغلب الألعاب الرياضية تعتمد على مكونات ألقدره التوافقيه والادراكيه الحسيه بوصفها احد العناصر الاساسيه في المستويات العليا لما توفره من قاعدة اقتران للصفات البدنيه والحر كيه وقدرات أجهزة الجسم الوظيفية , وفقا للأسس المعتمدة في بناء مهاراته, وعليه فان الارتقاء في درجات الأداء لتلك المتطلبات لايتم بلوغه ,ما لم تتفاعل الخبرات السمعية والبصرية والحس حركية لتشكيل الإدراك الشامل والصحيح الذي يهيئ للاعبه السيطرة التامة على الإيقاع الحركي سواء كان ذلك في ديناميكية الحركات والمهارات لتؤدى بما يناسب متطلبات الأداء .لذا وجدت الباحثتان ضعف الاعتماد على المؤشرات للقدرة التوافقية والقدرات الإدراكية الحسية الحركية والاستناد إلى مستويات الاستعداد مؤشرا منذ بداية التعلم الحركي ومدى التقدم في المستوى مقارنة بباقي المؤشرات الأخرى التي يبنى عليها تعلم الطالبة وتطورها في مادة جمناستك الأجهزة, وهدفت الدراسة الى التعرف على العلاقة بين بعض قدرات الإدراك الحسي – حركي المكاني ومستوى تعلم بعض مهارات جمناستك الأجهزة . واستعمل المنهج الوصفي على طالبات المرحلة الثالثة بكلية التربية الرياضية للبنات- جامعة بغداد.والبالغ عددهن (87)طالبة. للفترة من 2-3 ولغاية 13-3-2008م , في قاعة الجمناستك بالكلية التربية الرياضية للبنات- جامعة بغداد. وبعد جمع النتائج وتحليلها وفق الحقيبة الاحصائية استنتجت الباحثتان ماياتي : - وجود علاقة ارتباط معنوية بين بعض قدرات الادراك الحس حركي ومستوى تعلم بعض مهارات جمناستك الاجهزة .
This research deals with a shrinking method concernes with the principal components similar to that one which used in the multiple regression “Least Absolute Shrinkage and Selection: LASS”. The goal here is to make an uncorrelated linear combinations from only a subset of explanatory variables that may have a multicollinearity problem instead taking the whole number say, (K) of them. This shrinkage will force some coefficients to equal zero, after making some restriction on them by some "tuning parameter" say, (t) which balances the bias and variance amount from side, and doesn't exceed the acceptable percent explained variance of these components. This had been shown by MSE criterion in the regression case and the percent explained v

Show MoreThis research depends on the relationship between the reflected spectrum, the nature of each target, area and the percentage of its presence with other targets in the unity of the target area. The changes occur in Land cover have been detected for different years using satellite images based on the Modified Spectral Angle Mapper (MSAM) processing, where Landsat satellite images are utilized using two software programming (MATLAB 7.11 and ERDAS imagine 2014). The proposed supervised classification method (MSAM) using a MATLAB program with supervised classification method (Maximum likelihood Classifier) by ERDAS imagine have been used to get farthest precise results and detect environmental changes for periods. Despite using two classificatio

OMR technology is particularly useful for applications in which large numbers of hand-filled forms need to be processed quickly and with a great degree of accuracy. The technique is particularly popular with schools and universities for the reading in of multiple choice exam papers. This paper proposed OMRbased on Modify Multi-Connect Architecture (MMCA) associative memory, its work in two phases: training phase and recognition phase. The proposed method was also able to detect more than one or no selected choice. Among 800 test samples with 8 types of grid answer sheets and tota

From this relationship the values of variables are predicted. In this paper the multiple linear regression model and three covariates were studied in the presence of the problem of auto-correlation of errors when the random error distributed the distribution of exponential. Three methods were compared (general least squares, M robust, and Laplace robust method). We have employed the simulation studies and calculated the statistical standard mean squares error with sample sizes (15, 30, 60, 100). Further we applied the best method on the real experiment data representing the varieties of
... Show MoreA reduced-order extended state observer (RESO) based a continuous sliding mode control (SMC) is proposed in this paper for the tracking problem of high order Brunovsky systems with the existence of external perturbations and system uncertainties. For this purpose, a composite control is constituted by two consecutive steps. First, the reduced-order ESO (RESO) technique is designed to estimate unknown system states and total disturbance without estimating an available state. Second, the continuous SMC law is designed based on the estimations supplied by the RESO estimator in order to govern the nominal system part. More importantly, the robustness performance is well achieved by compensating not only the lumped disturbance, but also its esti
