التحليل الاحصائي لتجارب القياسات المكررة للبيانات المصنفة في حالة معالجتين وثلاث معالجات
...Show More Authors

من اهداف بعض التجارب هي معرفة تاثير التسلسلات المختلفة لبعض الادوية او التغذية او تجارب التعلم. وفي بعض الاحيان قد تكون الوحدات التجريبية نادرة لهذا نقوم باستخدام الوحدات التجريبية على نحو متكرر. او بسبب الميزانية المحدودة فان صاحب التجربة يخضع كل وحدة تجريبية لاختبارات عديدة ويطلق على هذا النوع من التجارب التي يتم فيها استخدام الوحدات التجريبية (الاشخاص) Subject على نحو متكرر من خلال تعريضها لسلسلة من المعالجات المختلفة اسم تجارب القياسات المكررة. وكانت البيانات لجميع هذه التجارب من النوع الكمي. ولكن في بعض الاحيان نواجه الدراسات التي فيها مستويات المتغيرات معرفة على اساس الرتب فقط حيث ان الاهتمام سوف يكون على عدد المشاهدات عند كل مستو من مستويات المتغير وان هذا النوع من البيانات يطلق عليه اسم البيانات المصنفة
(
Categorical Count Data) .

تركزت الدراسة في هذا البحث  على اختبارات القياسات المكررة للبيانات المصنفة  حيث تم دراسة كل من الاختبارات التالية (Cochran, Mc Nemar, Ireland & Kullback, Stuart, Bhapkar, Ireland & Ku & Kullback) للقياسات المكررة ذات المعالجتين وكل معالجة بمستويين (صنفين) ودراسة كل من الاختبارات التالية (Stuart, Bahapkar, Ireland & Ku & Kullback) للقياسات المكررة ذات معالجتين وكل معالجة بأكثر من مستويين (صنفين) ودراسة ايضا اختبارات
(
Cochran, Ireland & Kullback,) واختبارات المربعات الصغرى الموزونة WLS للقياسات المكررة  ذات ثلاث معالجات وكل معالجة بمستويين وتم تطبيق جميع الاختبارات على بيانات حقيقية حيث تمت المقارنة بين الاختبارات من خلال النتائح التي تم الوصول اليها وبالتالي التوصل الى مجموعة من الاستنتاجات.

The development in manufacturing computers from both (Hardware and Software) sides, make complicated robust estimators became computable and gave us new way of dealing with the data, when classical discriminant methods failed in achieving its optimal properties especially when data contains a percentage of outliers. Thus, the inability to have the minimum probability of misclassification. The research aim to compare robust estimators which are resistant to outlier influence like robust H estimator, robust S estimator and robust MCD estimator, also robustify misclassification probability with showing outlier influence on the percentage of misclassification when using classical methods. ,the other

The Stability Conditions of the Pump Structure Vibration
...Show More Authors

 The general approach of this research is to assume that the small nonlinearity can be separated from the linear part of the equation of motion. The effect of the dynamic fluid force on the pump structure system is considered vibrates at its natural frequency but the amplitude is determined by the initial conditions. If the motion of the system tends to increase the energy of the pump structure system, the vibration amplitude will increase and the pump structure system is considered to be unstable. A suitable MATLAB program was used to predict the stability conditions of the pump structure vibration. The present research focuses on fluid pump problems, namely, the role played by damping coefficient C, damping factor

Econometrics analysis of the impact of external shocks on foreign direct investment in Iraq for the period (1995-2016)
...Show More Authors

The external shocks are one of the phenomena that the Iraqi economy is exposed to over a period of time. It is referred to as changes and events that come from outside the economic system and extends to many economic variables. However, foreign direct investment may be severely affected due to the extreme sensitivity to changes and local and international developments. This type of trauma and its characteristics to help manage and cope with external shocks, and in order to avoid the standard problems experienced by some models of simple linear regression, multi-linear regression models were used with variables Scientific and other dummy variables .

MCD (LOS MARCADORES DISCURSIVOS) The pragmatic analysis of discourse markers (The argumentative texts of the ABC newspaper as a model): El análisis pragmático de los marcadores discursivos (Los textos argumentativos del periódico ABC como modelo)
...Show More Authors

When writing a text, such as a newspaper article, various types of discourse markers are frequently used to group sentences into paragraphs and parts in order to establish a discourse with certain functions, such as coordination, orientation, emphasizing the concepts presented, etc. It should also be noted that this type of mark exists in both written and spoken language. Therefore, it is convenient to dedicate a chapter to these linguistic elements to clarify their use and their classification, which is mainly based on Jose Portolés (2001), as well as the main features, specifically their features (prosodic, morphological, semantic and pragmatic).

Methods of using the periodic chart in the case of the missing values of the stable AR model (2)
...Show More Authors

In this study, we investigate the behavior of the estimated spectral density function of stationary time series in the case of missing values, which are generated by the second order Autoregressive (AR (2)) model, when the error term for the AR(2) model has many of continuous distributions. The Classical and Lomb periodograms used to study the behavior of the estimated spectral density function by using  the simulation.
