...Show More Authors

يتنامى يوما بعد يوم استخدام السيارات وتتعاضم اعدادها ، فهذا هو عصر السرعة، وخاصة في مجال النقل والمواصلات، والتي تتحقق باستخدام وسائل النقل المختلفة ومن بينها السيارات، وبالتالي اصبحت هذه الوسيلة ضرورية لتحقيق هذه السرعة ومن ضرورات الحياة في انجاز الاعمال.

وتتبارى مصانع السيارات فيما بينها لانتاج انواع السيارات بمواصفات عالية من المتانة والامان والراحة، وفي ذات الوقت اصبحت هندسة الطرق علما متخصصا في مجال تصميم وانجاز الطرق الخارجية والشوارع الداخلية في المدن بهدف الوصول الى اعلى انسيابية في حركة سير السيارات والمشاة وبما يحقق اعلى درجة من الامان فيها. ومن جهة ثالثة يزداد اهتمام الحكومات والمنظمات والاتحادات الوطنية والعالمية بخصوص سن القوانين واصدار الانظمة والتعليمات والتوجيهات الهادفة الى رفع درجة الامان في حركة سير السيارات .

رغم كل هذا وذاك تتعاضم وباتجاه معاكس اخطار السيارات والحوادث المتحققة عنها ، وبالتالي تتعاظم الخسائر البشرية والمادية الناجمة عنها ، حتى اعدت اخطار السيارات من الاوبئة التي تعاني منها الدول ومظهرا معيبا من مظاهر التكنلوجيا مما حدا بالعديد من الباحثين والمنظمات والحكومات الى التصدي لهذه الظاهرة بالبحث والتحليل في محاولة للكشف عن اسبابها والعمل على تحجيم تلك الاسباب والقضاء عليها او تقليل الخسائر الناتجة عنها .

ويعد هذا البحث ضمن سياق الدراسات والبحوث التي تتناول موضوع تحليل اخطار السيارات ، الا انه ذو منحى مختلف بعض الشيء، اذ يعمد الى تحليل هذه الاخطار باربعة اتجاهات في ذات الوقت: الاول في في تحديد اخطار السيارات والاهمية النسبية لكل منها، والثاني في تحديد الاسباب الرئيسة والفرعية والثانوية لهذه الاخطار والاهمية النسبية لكل منها، والثالث في تحديد الخسائر البشرية والمادية المتحققة من هذه الاخطار ، واخيرا فان الاتجاه الرابع هو في تحديد اساليب مواجهة هذه الاخطار من خلال التصدي لأسبابها. ويتكون البحث من اربعة اقسام : تضمن القسم الاول استعراضا لمفهوم الخطر ومفهوم تحليل الخطر اضافة الى الاساليب العلمية المستخدمة في عملية التحليل، فيما يتضمن القسم الثاني منهجية البحث مستعرضا مشكلة البحث وهدفه وحدوده والاساليب المعتمدة في تحليله وفي جمع البيانات، اضافة الى عدد من الدراسات السابقة في هذا المجال ، اما القسم الثالث فيتضمن تحليل اخطار السيارات في العراق معتمدا على استعراض انواع الاخطار وحجم تحقق كل منها واهميتها النسبية وكذلك الاسباب (الرئيسة والفرعية والثانوية) والنتائج السلبية المتحققة منها واساليب المواجهة، واخيرا تضمن القسم الرابع الاستنتاجات والتوصيات التي تمخض عنها البحث.

Univariate and Multivariate Exploration of Resilient Modulus for Warm Mix Asphalt Mixtures
...Show More Authors

This paper predicts the resilient modulus (Mr) for warm mix asphalt (WMA) mixtures prepared using aspha-min. Various predictor variables were analyzed, including asphalt cement types, asphalt contents, nominal maximum aggregate sizes (NMAS), filler content, test temperatures, and loading times. Univariate and multivariate analyses were conducted to examine the behavior of each predictor variable individually and collectively. Through univariate analysis, it was observed that Mr exhibited an inverse trend with asphalt cement grade, NMAS, test temperature, and load duration. Although Mr increased slightly with higher filler and asphalt content, the magnitude of this increase was minimal. Multivariate analysis revealed that the rate of change

Estimation of Time of Survival Rate by Using Clayton Function for the Exponential Distribution with Practical Application
...Show More Authors

Each phenomenon contains several variables. Studying these variables, we find mathematical formula to get the joint distribution and the copula that are a useful and good tool to find the amount of correlation, where the survival function was used to measure the relationship of age with the level of cretonne in the remaining blood of the person. The Spss program was also used to extract the influencing variables from a group of variables using factor analysis and then using the Clayton copula function that is used to find the shared binary distributions using multivariate distributions, where the bivariate distribution was calculated, and then the survival function value was calculated for a sample size (50) drawn from Yarmouk Ho

Modified Optimization Algorithms for Infinite Integro-Differential Equations via Generalized Laguerre Polynomials
...Show More Authors

This study emphasizes the infinite-boundary integro-differential equation. To examine the approximate solution of the problem, two modified optimization algorithms are proposed based on generalized Laguerre functions. In the first technique, the proposed method is applied to the original problem by approximating the solution using the truncated generalized Laguerre polynomial of the unknown function, optimizing coefficients through error minimization, and transforming the integro-differential equation into an algebraic equation. In contrast, the second approach incorporates a penalty term into the objective function to effectively enforce boundary and integral constraints. This technique reduces the original problem to a mathematical optimi

Estimation of Surface Runoff to Bahr AL-Najaf
...Show More Authors

The estimation of the amounts of Surface runoff resulting from rainfall in the water basins is of great importance in water resources management. The study area (Bahr Al-Najaf) is located on the western edge of the plateau and the southwestern part of the city center of Najaf, with an area of 2729.4 (km2). The soil and water assessment tool (SWAT) with ArcGIS software was used to simulate the runoff coming from the three main valleys (Kharr (A and B)), Shoaib Al-Rahimawi, and Maleh), that contribute the flow to the study area. The results of the model showed that the SWAT software was successfully simulating the flow conditions based on the coefficient of determination (R2), the Nash coefficient (NS

A graph-based multi-sample test for identifying pathways associated with cancer progression
...Show More Authors

Cancer is in general not a result of an abnormality of a single gene but a consequence of changes in many genes, it is therefore of great importance to understand the roles of different oncogenic and tumor suppressor pathways in tumorigenesis. In recent years, there have been many computational models developed to study the genetic alterations of different pathways in the evolutionary process of cancer. However, most of the methods are knowledge-based enrichment analyses and inflexible to analyze user-defined pathways or gene sets. In this paper, we develop a nonparametric and data-driven approach to testing for the dynamic changes of pathways over the cancer progression. Our method is based on an expansion and refinement of the pathway bei

Evaluation of the Mishrif Formation Using an Advanced Method of Interpretation
...Show More Authors

The Mishrif Formation is one of the most important geological formations in Iraq consisting of limestone, marl, and shale layers since it is one of the main oil producing reservoirs in the country, which contain a significant portion of Iraq's oil reserves. The formation has been extensively explored and developed by the Iraqi government and international oil companies, with many oil fields being developed within it. The accurate evaluation of the Mishrif formation is key to the successful exploitation of this field. However, its geological complexity poses significant challenges for oil production, requiring advanced techniques to accurately evaluate its petrophysical properties.

Optimum Operation Management Effect of Main Sewage Pumping Stations on Trunk Sewer Deterioration
...Show More Authors

Sewage pumping stations are considered an important part of any sewerage system. Pumps failure in these stations means that the pumps are unable to work at the design requirement (flow capacity and head) and that may cause sewer overflow and flooding leading to sewer deterioration. In this paper, two main sewage pumping stations in Baghdad city were selected as case studies, Al- Habibia and Al-Ghazali located on Zublin trunk sewer 3000 mm and Baghdad trunk sewer 1200-2100 respectively. This study focused mainly on the operation of main sewage pumping stations and their effect, both directly and indirectly, on changing hydraulic properties, which leads to an increase in the deterioration of sewage pipes. The hydraulic analysis was co
