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.

Dynamic Analysis of Fluid – Structure Interaction of Axial Fan System
...Show More Authors

Fluid-structure interaction method is performed to predict the dynamic characteristics of axial fan system. A fluid-structure interface physical environment method (monolithic method) is used to couple the fluid flow solver with the structural solver. The integration of the three-dimensional Navier-Stokes equations is performed in the time Doman, simultaneously to the integration of the three dimensional structural model. The aerodynamic loads are transfer from the flow to structure and the coupling step is repeated within each time step, until the flow solution and the structural solution have converged to yield a coupled solution of the aeroelastic set of equations. Finite element method is applied to solve numerically

FREE VIBRATION ANALYSIS OF COMPOSITE LAMINATED PLATES USING HOST 12
...Show More Authors

This paper presents an application of a Higher Order Shear Deformation Theory (HOST 12) to problem
of free vibration of simply supported symmetric and antisymmetric angle-ply composite laminated plates.
The theoretical model HOST12 presented incorporates laminate deformations which account for the effects
of transverse shear deformation, transverse normal strain/stress and a nonlinear variation of in-plane
displacements with respect to the thickness coordinate – thus modeling the warping of transverse crosssections more accurately and eliminating the need for shear correction coefficients. Solutions are obtained in
closed-form using Navier’s technique by solving the eigenvalue equation. Plates with varying number of

Thermal Performance Analysis of Compact Heat Exchangers for Thermoelectric Generators
...Show More Authors

The efficiency of internal combustion engines (ICE) is usually about thirty percent of the total energy of the fuel. The residual energy is lost in the exhaust gas, the lubrication, and the cooling water in the radiators. Recently much of the researcher’s efforts have focused on taking advantage of wasted energy of the exhaust gas. Using a thermoelectric generator (TEG) is one of the promising ways. However, TEG depends entirely on the temperature difference, which may be offered by the exhaust muffler. An experimental test has been conducted to study the thermal performance of a different muffler internal design. The researchers resort to the use of lost energy in an ICE using TEG, which is one of the ways to take adv

Error Analysis of Stonex X300 Laser Scanner Close-range Measurements
...Show More Authors

This research reports an error analysis of close-range measurements from a Stonex X300 laser scanner in order to address range uncertainty behavior based on indoor experiments under fixed environmental conditions. The analysis includes procedures for estimating the precision and accuracy of the observational errors estimated from the Stonex X300 observations and conducted at intervals of 5 m within a range of 5 to 30 m. The laser 3D point cloud data of the individual scans is analyzed following a roughness analysis prior to the implementation of a Levenberg–Marquardt iterative closest points (LM-ICP) registration. This leads to identifying the level of roughness that was encountered due to the range-finder’s limitations in close

Potentiality Analysis of Physical Development of International Airports Surrounding Zones
...Show More Authors

The areas surrounding Iraqi international airports generally suffer from a lack of interest in their planning in a manner compatible with the airport with the absence of integrated planning between the airport and the city. From here, the search problem appears. It is represented by a lack of interest in the integration of urban planning and airport planning and the lack of a clear policy to deal with the areas surrounding international airports. A desire to achieve the research aims to introduce compatible uses in the vicinity of airports and review the planning and global directions for dealing with the areas surrounding the airports within urban areas. In contrast, the second aspect of the research aims to assess the
