...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.

Synthesis, Spectroscopic, Characterization and Biological Activities of Schiff Base Ligand and Metal Complexes of Some Metal (II) Salts with Anthranilic Acid
...Show More Authors

Schiff base N,N'-Bis-(4-dimethylamino-benzylidene)-benzene-1,4-diamine has been synthesized from 4-dimethylaminobenzenaldehyde and benzene-1,4-diamine. The structure of Schiff base was obtained by (C.H.N.) microanalysis, Mass, 1HNMR, FT-IR and UV-Vis spectral methods and thermal analysis. Metal mixed ligand complexes of some metal(II) salts with Schiff base ligand and anthranilic acid were prepared in the molar ratio (1:2:2), (Metal):(SBL)2:(Anthra)2, (SBL)= Schiff base ligand, (Anthra) =anthranilic acid and Metal= Co(II), Ni(II), Cu(II), Zn(II), Cd(II) and Hg(II). The thermal behaviour (TGA) of the complexes was studied. The prepared complexes identified by using mass, thermal analysis, FT.IR and UV-Vis spectrum methods, on otherwise flame

User Oriented Calibration Method for Stonex X300 Terrestrial Laser Scanner
...Show More Authors

    Terrestrial laser scanners (TLSs) are 3D imaging systems that provide the most powerful 3D representation and practical solutions for various applications. Hence this is due to effective range measurements, 3D point cloud reliability, and rapid acquisition performance. Stonex X300 TOF scanner delivered better certainty in far-range than in close-range measurements due to the high noise level inherent within the data delivered from Time of Flight (TOF) scanning sensors. However, if these errors are manipulated properly using a valid calibration model, more accurate products can be obtained even from very close-range measurements. Therefore, to fill this gap, this research presents a user-oriented target-based calibration routine to

Comparison Different Estimation Methods for the Parameters of Non-Linear Regression
...Show More Authors

   Nonlinear regression models are important tools for solving optimization problems. As traditional techniques would fail to reach satisfactory solutions for the parameter estimation problem.  Hence, in this paper, the BAT algorithm  to estimate the parameters of  Nonlinear Regression models is used . The simulation study is considered to investigate the performance of the proposed algorithm with the maximum likelihood (MLE) and Least square (LS) methods. The results show that the Bat algorithm provides accurate estimation and it is satisfactory for the parameter estimation of the nonlinear regression models than MLE and LS methods depend on Mean Square error.

Analyzing Laser Speckle Pattern Using the Discrete Cosine Transform
...Show More Authors

The use of Cosine transform to analyze the model-noise pattern alteration with different vibration model applied on multimode fiber optics are studied. It's results compared with the Fourier transform to perform the same analysis using total frequency difference and the computation time, which almost coincide for the both transforms. A discussion for the results and recommendation are introduced.

Numerical Simulation of Thermal-Hydrodynamic Behavior within Solar Air Collector
...Show More Authors

Solar collectors, in general, are utilized to convert the solar energy into heat energy, where it is employed to generate electricity. The non-concentrating solar collector with a circular shape was adopted in the present study. Ambient air is heated under a translucent roof where buoyant air is drawn from outside periphery towards the collector center (tower base). The present study is aimed to predict and visualize the thermal-hydrodynamic behavior for airflow under inclined roof of the solar air collector, SAC. Three-dimensional of the SAC model using the re-normalization group, RNG, k−ε turbulence viscus model is simulated. The simulation was carried out by using ANSYS-FLUENT 14.5. The simulation

Earthquake Hazard Mitigation for Uncertain Building Systems Based on Adaptive Synergetic Control
...Show More Authors

This study presents an adaptive control scheme based on synergetic control theory for suppressing the vibration of building structures due to earthquake. The control key for the proposed controller is based on a magneto-rheological (MR) damper, which supports the building. According to Lyapunov-based stability analysis, an adaptive synergetic control (ASC) strategy was established under variation of the stiffness and viscosity coefficients in the vibrated building. The control and adaptive laws of the ASC were developed to ensure the stability of the controlled structure. The proposed controller addresses the suppression problem of a single-degree-of-freedom (SDOF) building model, and an earthquake control scenario was conducted and simulat

EXPERIMENTAL AND THEORETICAL INVESTIGATIONS FOR BEHAVIOR OF PRECAST CONCRETE GIRDERS WITH CONNECTIONS
...Show More Authors

This research presents experimental and theoretical investigation of 15 reinforced concrete spliced and nonspliced girder models. Splices of hooked dowels and cast in place joints, with or without strengthening steel plates were used. Post-tensioning had been used to enhance the splice strength for some spliced girders. The ANSYS computer program was used for analyzing the spliced and non-spliced girders. A nonlinear three dimensional element was used to represent all test girders. The experimental results have shown that for a single span girder using steel plate connectors in the splice zone has given a sufficient continuity to resist flexural stresses in this region. The experimental results have shown that the deflection of hooked do

Laplace Domain Modeling of Power Components for Transient Converter-Grid Interaction Studies
...Show More Authors

This paper introduces a Laplace-based modeling approach for the study of transient converter-grid interactions. The proposed approach is based on the development of two-port admittance models of converters and other components, combined with the use of numerical Laplace transforms. The application of a frequency domain method is aimed at the accurate and straightforward computation of transient system responses while preserving the wideband frequency characteristics of power components, such as those due to the use of high frequency semiconductive switches, electromagnetic interaction between inductive and capacitive components, as well as wave propagation and frequency dependence in transmission systems.
