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.

Using Mehar method to change fuzzy cost of fuzzy linear model with practical application
...Show More Authors

  Many production companies suffers from big losses because of  high production cost and low profits for several reasons, including raw materials high prices and no taxes impose on imported goods also consumer protection law deactivation and national product and customs law, so most of consumers buy imported goods because it is characterized by modern specifications and low prices.

  The production company also suffers from uncertainty in the cost, volume of production, sales, and availability of raw materials and workers number because they vary according to the seasons of the year.

  I had adopted in this research fuzzy linear program model with fuzzy figures

Study on Flow Characteristics and Heat Transfer Behavior Around Different Geometrical Corrugated Extended Surfaces
...Show More Authors

Abstract

The current study presents numerical investigation of the fluid (air) flow characteristics and convection heat transfer around different corrugated surfaces geometry in the low Reynolds number region (Re<1000). The geometries are included wavy, triangle, and rectangular. The effect of different geometry parameters such as aspect ratio and number of cycles per unit length on flow field characteristics and heat transfer was estimated and compared with each other. The computerized fluid dynamics package (ANSYS 14) is used to simulate the flow field and heat transfer, solve the governing equations, and extract the results. It is found that the turbulence intensity for rectangular extended surface was larg

Data Classification using Quantum Neural Network
...Show More Authors

In this paper, integrated quantum neural network (QNN), which is a class of feedforward

neural networks (FFNN’s), is performed through emerging quantum computing (QC) with artificial neural network(ANN) classifier. It is used in data classification technique, and here iris flower data is used as a classification signals. For this purpose independent component analysis (ICA) is used as a feature extraction technique after normalization of these signals, the architecture of (QNN’s) has inherently built in fuzzy, hidden units of these networks (QNN’s) to develop quantized representations of sample information provided by the training data set in various graded levels of certainty. Experimental results presented here show that

Experimental and Theoretical Determination of Settlement of Shallow Footing on Liquefiable Soil
...Show More Authors

A high settlement may take place in shallow footing when resting on liquefiable soil if subjected to earthquake loading. In this study, a series of shaking table tests were carried out for shallow footing resting on sand soil. The input motion is three earthquake loadings (0.05g, 0.1g, and 0.2g). The study includes a reviewing of theoretical equations (available in literatures), which estimating settlement of footings due to earthquake loading, calibration, and verification of these equations with data from the shaking table test for improved soil by grouting and unimproved soil. It is worthy to note that the grouting materials considered in this study are the Bentonite and CKD slurries. A modification to the seismic set

Three-Dimensional Explicit Finite Element Simulation of Piled-Raft Foundation
...Show More Authors

This paper aims to validate a proposed finite element model to be adopted in predicting displacement and soil stresses of a piled-raft foundation. The proposed model adopts the solid element to simulate the raft, piles, and soil mass. An explicit integration scheme has been used to simulate nonlinear static aspects of the piled-raft foundation and to avoid the computational difficulties associated with the implicit finite element analysis.

The validation process is based on comparing the results of the proposed finite element model with those of a scaled-down experimental work achieved by other researchers. Centrifuge apparatus has been used in the experimental work to generate the required stresses to simulate t

Proposed family speech recognition
...Show More Authors

Speech recognition is a very important field that can be used in many applications such as controlling to protect area, banking, transaction over telephone network database access service, voice email, investigations, House controlling and management ... etc. Speech recognition systems can be used in two modes: to identify a particular person or to verify a person’s claimed identity. The family speaker recognition is a modern field in the speaker recognition. Many family speakers have similarity in the characteristics and hard to identify between them. Today, the scope of speech recognition is limited to speech collected from cooperative users in real world office environments and without adverse microphone or channel impairments.

Development and Verification of the Capacity Curve for Two Dimensional Reinforced Concrete Moment-Resisting Frames System under Earthquake Loading
...Show More Authors

Pushover analysis is an efficient method for the seismic evaluation of buildings under severe earthquakes. This paper aims to develop and verify the pushover analysis methodology for reinforced concrete frames. This technique depends on a nonlinear representation of the structure by using SAP2000 software. The properties of plastic hinges will be defined by generating the moment-curvature analysis for all the frame sections (beams and columns). The verification of the technique above was compared with the previous study for two-dimensional frames (4-and 7-story frames). The former study leaned on automatic identification of positive and negative moments, where the concrete sections and steel reinforcement quantities the

Age Estimation Using Support Vector Machine
...Show More Authors

Recently there has been an urgent need to identify the ages from their personal pictures and to be used in the field of security of personal and biometric, interaction between human and computer, security of information, law enforcement. However, in spite of advances in age estimation, it stills a difficult problem. This is because the face old age process is determined not only by radical factors, e.g. genetic factors, but also by external factors, e.g. lifestyle, expression, and environment. This paper utilized machine learning technique to intelligent age estimation from facial images using support vector machine (SVM) on FG_NET dataset. The proposed work consists of three phases: the first phase is image preprocessing include four st
