تقييم أداء النظام الخدمي في مستشفى بغداد التعليمي العام وإعادة تشكيل النظام باستخدام أسلوب Q-GERT
...Show More Authors

أن المساهمة الأساسية لهذا البحث هي وصف كيفية تحليل الأنظمة الخدمية المعقدة ذات خصائص الطابور الموجودة في مستشفى بغداد التعليمي العام باستخدام تقنيات شبكية وهي تقنية أسلوب (Q – GERT ) وهي اختصار من الكلمات : Queuing theory _ Graphical Evaluation and Review Technique أي أسلوب التقييم والمراجعة البياني حيث سوف يتم معرفة حركة انسيابية المرضى داخل النظام وبعد استخدام هذا المدخل سيتم تمثيل النظام على هيئة مخطط شبكي احتمالي وتحليله ومعرفة التوزيعات الاحصائية الملائمة لأوقات الوصول والمغادرة حيث تم استعمال البرنامج الجاهز (Win QSB ) ومحاكاة البيانات التي تم جمعها مباشرة من (9) قسم خدمي بالمستشفى وقتا مدته ساعتين أي (120 ) دقيقة خلال وقت الذروة من الساعة (12 – 10 ) ظهراً ، ولغرض تحليل البيانات ومعرفة التوزيعات الإحصائية الملائمة فقد تم استخدام البرنامج الإحصائي الجاهز ( STATGRAPHICS PLUS 4.0 ) وتم اختبار البيانات بذات البرنامج باختبار حسن المطابقة ( (Good ness of fit ، وبعد تحليل البيانات تم التوصل إلى أن أفضل توزيع لأوقات الوصول كان التوزيع الطبيعي (Normal distribution ) وأفضل توزيع لأوقات المغادرة كان توزيع كاما (Gamma distribution) ولكافة الأقسام عدا قسمي التسجيل والصيدلية فاتبعتا التوزيع الطبيعي لأوقات الوصول والمغادرة ، حيث سوف يتم بناء النظام على شبكة طابور مؤلفة من العقد والفروع والتي من خلالها سوف نصل إلى عقد الانتظار ونقوم بمعالجة هذه العقد بوضع الحلول التي تؤدي إلى حل المعوقات الناجمة أثر الاختناق الناجم من الانتظار .

Q- Switched Nd:YAG Laser Annealing of Phosphorus Diffused Silicon Photodiodes
...Show More Authors

Improvement of optoelectrical characteristics of phosphorus diffused silicon photodiodes by Q-switched Nd:YAG laser pulses was investigated. Laser pulses have dissolved the precipitation of phosphorus resulted during thermal diffusion process. The experimental data show that responsivity higher than (0.32 A/W) at 850 nm can be achieved after laser annealing with (1.5 MW/cm2) for 6 shots.

On q-SZASZ- Mirakyan Operators of functions of Two Variables
...Show More Authors

In this paper, we define two operators of summation and summation-integral of q-type in two dimensional spaces. Firstly, we study the convergence of these operators and then we prove Voronovskaya- type asymptotic formulas for these operators.

Bifurcation Diagram of W(u_j;τ)-Function with (p,q)-Parameters
...Show More Authors

      This study aims to classify the critical points of functions with 4 variables and 8 parameters, we found the caustic for the certain function with the spreading of the critical points. Finally, as an application, we found the bifurcation solutions for the equation of sixth order with boundary conditions using the Lyapunov-Schmidt method in the variational case.

Topology of cubic bipolar structures and its application on Q-algebra
...Show More Authors

In this paper, we define a cubic bipolar subalgebra, $BCK$-ideal and $Q$-ideal of a $Q$-algebra, and obtain some of their properties and give some examples. Also we define a cubic bipolar fuzzy point, cubic bipolar fuzzy topology, cubic bipolar fuzzy base and for each concept obtained some of its properties.

Investigate Indian Costus Plasma Parameters using Q-Switched Laser Nd: YAG
...Show More Authors

The Indian costus plasma properties are investigated including electron temperature (Te), "electron density (ne)", "plasma frequency (fp)", " Debye sphere length", and amount of Debye(Nd),  using the spectrum of optical emission technique. There are several energies used, with ranging from 300 to 600 mJ. The Boltzmann Plot is used to calculate the temperature; where as Stark's Line Broadening is used to calculate the electron density. The Indian costus was spectroscopically examined in the air with the laser  at 10 cm away from the target and the optical fiber  at 0.5 cm away. The results were obtained for an electron temperature range of (1.8-2.2) electron volts (ev) and a wavelength range of (300-600) nm. The XRF analysis reveals th

The no parity problem causes determining is the most interesting case by doctors and researchers in this filed, because it helps them to pre-discovering of it, from this point the important of this paper is came, which tries to determine the priority causes and its fluency, thus it helps doctors and researchers to determine the problem and it’s fluency of increase or decrease the active sperm which fluencies of peregrinating. We use the censored regression (Tobit) model to analyze the data that contains 150 observations may by useful to whom it concern.

Treatment of Skin Hyperpigmentation using Q-Switched (1064nm and 532nm) Nd:YAG Laser
...Show More Authors

Hyperpigmentation is the increase in the natural color of the skin. The purpose of this study is to evaluate the efficacy and safety of Q-Switched Nd:YAG (1064 & 532 nm) Laser in treatment of skin hyper pigmentation. This study was done in the research clinic of Institute of laser for postgraduate Studies/University of Baghdad from October 2008 to the end of January 2009. After clinical assessment of skin hyperpigmentation color, twenty six patients were divided according to their lesions. Eight Patients with freckles, seven patients with melasma, four patients with tattoo. Cases with tattoo, were subdivided into amateur tattoos two, professional tattoos one, and one traumatic tattoo. Four Patients with post inflammatory hyperpigment
