يُمثل التوسع الحضري أحد أبرز التحولات الديموغرافية العالمية. وفي العراق، يكتسب هذا التحول بُعداً استثنائياً نتيجة للتغيرات السياسية، والأمنية، والاقتصادية الجذرية الممتدة من عام 1997 وحتى 2025، والتي أفرزت تبايناً مكانياً حاداً في مسارات النمو السكاني بين المراكز الحضرية. استندت هذه الدراسة إلى تحليل بيانات رسمية لـ 12 مركزاً حضرياً رئيسياً. وكشفت النتائج عن فجوة ديموغرافية واسعة؛ إذ برزت مدن إقليم كردستان (السليمانية وأربيل) كأقطاب للنمو الاستثنائي، في حين سجلت مدن أخرى معدلات بطيئة. وأظهر "تحليل البؤر الساخنة" (Hot Spot Analysis) غياب أي تجمعات مكانية ذات دلالة إحصائية، مما يؤكد أن أنماط النمو المرتفعة هي ظواهر محلية مدفوعة بديناميكيات خاصة بكل مدينة، وليست تمدداً إقليمياً. علاوة على ذلك، أثبت نموذج الانحدار الموزون جغرافياً (GWR) التباين المكاني لتأثير العوامل المستقلة؛ حيث لعب توفر الاستقرار الأمني دوراً حاسماً كعامل جذب قوي في مدن كالسليمانية متجاوزاً تأثير المتغيرات الاقتصادية. وتخلص الدراسة إلى أن السياسات التخطيطية الحضرية الموحدة غير فعالة في السياق العراقي، موصيةً بضرورة تبني استراتيجيات مكانية مخصصة تستجيب لمتطلبات التنمية المتفاوتة لكل منطقة على حدة.
The aim of this study was to Identifying The Effect of using Linear programming and Branching programming by computer in Learning and Retention of movement concatenation(Linkwork) in parallel bars in Artistic Gymnastics. The searchers have used the experimental method. The search subject of this article has been taken (30) male - students in the second class from the College of Physical Education/University of Baghdad divided into three groups; the first group applied linear programming by computer, and the second group has been applicated branching programming by computer, while precision group used traditional method in the college. The researchers concluded the results by using the statistical bag for social sciences (spss) such as both

This research aims to describe the classification method applied to the dataset of multiple types of images (Synthetic Aperture Radar (SAR) images and non-SAR images). In such a classification, transfer learning was used followed by fine-tuning methods. Besides, pre-trained architectures were used on the known image database ImageNet. The model VGG16 was indeed used as a feature extractor and a new classifier was trained based on extracted features.The input data mainly focused on the dataset consist of five classes including the SAR images class (houses) and the non-SAR images classes (Cats, Dogs, Horses, and Humans). The Conv
... Show MoreRecognition is one of the basic characteristics of human brain, and also for the living creatures. It is possible to recognize images, persons, or patterns according to their characteristics. This recognition could be done using eyes or dedicated proposed methods. There are numerous applications for pattern recognition such as recognition of printed or handwritten letters, for example reading post addresses automatically and reading documents or check reading in bank.
One of the challenges which faces researchers in character recognition field is the recognition of digits, which are written by hand. This paper describes a classification method for on-line handwrit

better Separation of Concern (SOC) by providing mechanisms to identify all relevant points
in a program at which aspectual adaptations need to take place. This paper introduces a
banking application using of AOSD with security concern in information hiding.
The speech recognition system has been widely used by many researchers using different
methods to fulfill a fast and accurate system. Speech signal recognition is a typical
classification problem, which generally includes two main parts: feature extraction and
classification. In this paper, a new approach to achieve speech recognition task is proposed by
using transformation techniques for feature extraction methods; namely, slantlet transform
(SLT), discrete wavelet transforms (DWT) type Daubechies Db1 and Db4. Furthermore, a
modified artificial neural network (ANN) with dynamic time warping (DTW) algorithm is
developed to train a speech recognition system to be used for classification and recognition
purposes. T
This paper introduces a relation between resultant and the Jacobian determinant
by generalizing Sakkalis theorem from two polynomials in two variables to the case of (n) polynomials in (n) variables. This leads us to study the results of the type: , and use this relation to attack the Jacobian problem. The last section shows our contribution to proving the conjecture.

The semiempirical (PM3) and DFT quantum mechanical methods were used to investigate the theoretical degradation of Indigo dye. The chemical reactivity of the Indigo dye was evaluated by comparing the potential energy stability of the mean bonds. Seven transition states were suggested and studied to estimate the actually starting step of the degradation reaction. The bond length and bond angle calculations indicate that the best active site in the Indigo dye molecule is at C10=C11. The most possible transition states are examined for all suggested paths of Indigo dye degradation predicated on zero-point energy and imaginary frequency. The first starting step of the reaction mechanism is proposed. The change in enthalpy, Gibbs free energ
