تنفذ أجهزة اإلحصاء الدولية ومنها الجهاز المركزي لإلحصاء في العراقإحدى أجهزة وزارة التخطيط، تقوم بإجراء مسوح سنوية ودورية لإنتاج مؤشرات تقييم وتقويم أنشطة القطاعات الاقتصادية المختلفة. يتيح هذا الكم الهائل من البيانات بشكل سلسل زمني لهذه الأجهزة إنتاج مؤشرات جديدة، بما في ذلك القيم التنبؤية لمؤشرات رئيسية تستخدم في إعداد الخطط طويلة وقصيرة المدى. في عام 2015، قامت مديرية الإحصاء الزراعي في الجهاز المركزي للإحصاء ببناء منظومة زمنية لمؤشرات الإحصاء الزراعي، وهذه خطوة أولى نحو بناء نماذج تنبؤية لهذه المؤشرات تساعدنا على رؤية مستقبلية. يهدف البحث إلى تحديد أفضل نموذج إحصائي للاستخدام في تنبؤ المساحات المزروعة لمحصول الذرة الصفراء في العراق للفترة 2015-2020 باستخدام بيانات السلسلة الزمنية للأعوام 1949-2014، بطول فترة 65 سنة. تم تطبيق أسلوب بوكس-جنكينز، وأظهرت النتائج أن النموذج الأنسب هو نموذج ARIMA (0,1,2) مقارنة بعدة نماذج أخرى باستخدام معايير إحصائية مختلفة لاختيار النموذج المناسب. توصي الدراسة وزارة الزراعة ووزارة التجارة بالاعتماد على القيم التنبؤية في إعداد الخطط الزراعية والتسويقية، وتوصي العاملين في الجهاز المركزي للإحصاء باعتماد هذا النموذج في تنبؤ مساحات المحاصيل واعتماد منهجية البحث في بناء نماذج تنبؤية لمؤشرات منظومة السلسلة الزمنية للإحصاءات الزراعية الأخرى.
This research was carried out to study the effect of plants on the wetted area for two soil types in Iraq and predict an equation to determine the wetted radius and depth for two different soil types cultivated with different types of plants, the wetting patterns for the soils were predicted at every thirty minute for a total irrigation time equal to 3 hr. Five defferent discharges of emitter and five initial volumetric soil moisture contents were used ranged between field capacity and wilting point were utilized to simulate the wetting patterns. The simulation of the water flow from a single point emitter was completed by utilized HYDRUS-2D/3D software, version 2.05. Two methods were used in developing equations to predict the domains o

Show MoreThis paper aims to study the damage generated due to creep-fatigue interaction behaviors in solid polyamide 6,6 and its composites that include 1%wt of carbon nanotubes or 30% wt short carbon fiber prepared by an injection technique. The investigation also includes studying the influence of applied temperatures higher than the glass transition temperatures on mechanical properties. The obtained results showed that the addition of reinforcement materials increased all the mechanical properties, while the increase in test temperature reduced all mechanical properties, especially for polyamide 6,6. The creep-fatigue interaction resistance also improved due to the addition of reinforcement materials by inc

Sociology has become an academic discipline recognized in the United States of America in the late nineteenth century, particularly, after the establishment of the first department of sociology in the University of Chicago in 1892. That was during the period of the rapid industrialization and sustainable growth of the Chicago City. The Chicago School relied on Chicago City in particular, as one of the American cities that grew and expanded rapidly in the first two decades of the twentieth century. At the end of the nineteenth centur

These changes overshadowed the nature of the work of the international organization, especially its first and most important executive organ (the Security Council). This has sometimes weakened and dulled the Security Council's role in performing the tasks stipulated in the Charter of the Organization, which has led the Organization itself to work on reforms within it in general and to seek reforms in the Security Council in particular. Academic and advisory efforts were made to submit proposals for amendment to be reflected on the Council's performance effectiveness.
