مقترح اسلوب IRWs الحصين لتقدير أنموذج الانحدار المقسم لحركة حمولة قاع نهر دجلة ونقطة التغيير لكمية تصريف المياه عند مدينة بغداد
...Show More Authors

              يتكون الانحدار المقسم من عدة أقسام تفصل بينها نقاط انتماء مختلفة، فتظهر حالة عدم التجانس الناشئة من عملية فصل الأقسام ضمن عينة البحث. ويهتم هذا البحث في تقدير موقع نقطة التغيير بين الأقسام وتقدير معلمات الأنموذج، واقتراح طريقة تقدير حصينة ومقارنتها مع بعض الطرائق المستعملة في الانحدار الخطي المقسم. وقد تم استعمال أحد الطرائق التقليدية (طريقة Muggeo) لإيجاد مقدرات الإمكان الأعظم بالأسلوب التكراري للأنموذج ونقطة التغيير معاً، واستعمال أحد الطرائق الحصينة (طريقة IRWm) والتي تعتمد على استعمال تقنية M-estimator الحصين في أسلوب التقسيم وباستعمال دالة الوزن Tukey.  وتكمن مساهمتنا في هذا البحث في اقتراح استعمال تقنية S-estimator الحصينة وباستعمال دالة الوزن Tukey، للحصول على طريقة حصينة  ضد حالات انتهاك شرط التوزيع الطبيعي للأخطاء العشوائية أو تأثير القيم الشاذة، وستدعى هذه الطريقة IRWs. وقد تم تطبيق الطرائق المذكورة آنفاً على مجموعة بيانات حقيقية متعلقة بحمولة قاع نهر دجلة/ مدينة بغداد كمتغير استجابة وكمية تصريف المياه كمتغير توضيحي. وقد أظهرت نتائج المقارنة أفضلية الطريقة المقترحة.

HF Wave Propagation Prediction Based On Passive Oblique Ionosonde
...Show More Authors

High frequency (HF) communications have an important role in long distances wireless communications. This frequency band is more important than VHF and UHF, as HF frequencies can cut longer distance with a single hopping. It has a low operation cost because it offers over-the-horizon communications without repeaters, therefore it can be used as a backup for satellite communications in emergency conditions. One of the main problems in HF communications is the prediction of the propagation direction and the frequency of optimum transmission (FOT) that must be used at a certain time. This paper introduces a new technique based on Oblique Ionosonde Station (OIS) to overcome this problem with a low cost and an easier way. This technique uses the

Principles of war and jihad to protect the environment and civilians in times of war in Islamic Sharia
...Show More Authors

The use of destructive weapons in wars without restrictions and controls, which eat green and dry land, pollute the environment and cause genocide, has become the problem of the times.

International conventions for the protection of the environment during armed conflicts are characterized by generality, ambiguity, and open to interpretation by the participating states in the agreement, and each state interprets these texts to serve its interests, but the Islamic Sharia stipulates the prohibition of the use of these comprehensive destructive weapons in an unambiguous manner, As stated in the Holy Quran:
