Abstract: اجري بحث حاسوبي في مجال بصريات الجسيمات المشحونة. يهتم البحث بتصميم منظومات عدسات كهروسكونية بوجود وعدم وجود تاثير عدم التراصف تعمل تحت ظروف تكبير مختلفة.ان توزيع مجال الجهد لعدسه احادية الجهد وعدسة مغمورة كهروسكونية تم تمثيله بدوال تحليلية. تم حل معادلة الاشعة المحورية للمجالات المقترحة لايجاد مسار الجسيمات المشحونة المارة في كل عدسة. ومن توزيع الجهد المحوري ومشتقتيه الاولى والثانية .تم حساب الخواص البصرية كالبعد البؤري والزيغين الكروي واللوني. كذلك تم ايجاد شكل اقطاب كل عدسة كهروسكونية ببعدين وبثلاثة ابعاد. ويعتمد الزيوغ في العدسات الكهروسكونية اعتمادا كبيرا على تراصف الاقطاب، وقد وجد انه عامل مهم يؤثر على الشكل الهندسي لمنظومة العدسة الكهروسكونية. ان نتائج هذه الدراسة لا تبرهن نظريا" امكانية تصميم منظومات عدسة كهروسكونية بزيوغ واطئة فحسب بل تبين امكانية تصنيع مثل هذه العدسات عمليا". | A computational investigation has been carried out in the field of charged - particle optics. The work is concerned with the design of electrostatic lenses with and without misalignment effect operated under different magnification conditions. The potential field distributions of einzel and immersion electrostatic lenses have been represented by analytic functions. The paraxial ray equation has been solved for the proposed fields to determine the trajectory of the charged particles traversing each lens. From the axial potential distribution and its first and second derivatives, the optical properties such as the focal length and spherical and chromatic aberrations have been compute. The electrode shape of each electrostatic lens has been determined in the two - and three - dimensions. The aberration of the electrostatic lens is highly dependent on the alignment of the electrodes and it has been found to be an important parameter affecting the geometry of the electrostatic lens system. The results of this investigation not only prove in theory the possibility of designing electrostatic lens systems with low aberration but also show the possibility of constructing such lenses in practice

Abstract: يتضمن البحث دراسة عملية لتحديد تراكيز اليورانيوم وغاز الرادون في التربة والماء لمناطق من بغداد وكربلاء والبصرة وللتعرف على مدى تلوث تلك المناطق بالمواد المشعة بعد احداث الحرب على العراق عام 2003 .تضمن الجزء الاول ايجاد تراكيز اليورانيوم في التربة والماء باستخدام كاشف الاثر (CR - 39) حيث استخدم التفاعل U - 235(n,f)U - 236 كمصدر لشظايا الانشطار النووي وذلك بقصف نواة اليورانيوم U - 235 بالنيوترونات الحرارية من المصدر النيوتروني (Am - Be) بفيض نيوتروني حراري (5 ×103 n cm - 2 s - 1) .تم تحديد التراكيز بالحسابات المعتمدة على المقارنة مع النماذج القياسية، وقد اوضحت النتائج التي حصلنا عليها ان اعلى تركيز لليورانيوم في التربة (2.73 ppm) في منطقة التاجي واعلى تركيز لليورانيوم في الماء (2.12 ppm) في منطقة العشار. تضمن الجزء الثاني ايجاد تراكيز غاز الرادون في التربة والماء باستخدام تقنية عد اثار جسيمات الفا المنبعثة من غاز الرادون فيكاشف الاثر (CR - 39) .وقد اوضحت النتائج التي حصلنا عليها ان اعلى تركيزلغاز الرادون في التربة (666 Bq/m3) في منطقة التاجي واعلى تركيز للرادون في الماء (14 Bq/m3) في منطقة العشار. اوضحت النتائج التي حصلنا عليها بان اعلى تراكيز لليورانيوم والرادون كان في منطقة التاجي ببغداد وفي منطقة العشار بالبصرة بسبب كون تلك المناطق مسرح للعمليات الحربية ضد العراق عام 2003 . | The aim of this project is to measure the uranium and radon gas concentrations in soil and water samples taken from regions situated in Baghdad, Karbala and Basrah, and to limit the level of contamination with radionuclides for these regions during the 2003 war.The first part contains the determination of uranium concentration in soil and water samples using CR - 39 Track detector. The nuclear reaction used a source of nuclear fission fragments is 235 - U (n , f) obtained by the bombardment of U - 235 with thermal neutrons from (Am - Be) source which has flux of (5 ×103 n cm - 2 s - 1). The concentrations values were calculated by a comparison with standard samples which prepared in our laboratory.The results obtained show that the higher concentration of uranium in soil samples was (2.73 ppm) in Al - Tajii region, and the higher concentration for water samples was (2.12 ppm) in Al - Ashaar region.The second part contains the determination of radon concentration in soil and water samples using alpha - emitters registration which emits from radon gas in (CR - 39) track detector.The results show that the higher concentration for radon gas in soil samples was (666 Bq/m3) in Al - Tajii region and in water samples was (14 Bq/m3) in Al - Ashaar region.The results show the maximum values of uranium and radon concentrations were in the (Al - Tajii and Al - Ashaar) regions, because these regions were a field of military operations during the 2003 war

Abstract: The spying and intrusion operation had been widely spread to steal the information especially with the development of computer networks (like, Internet). To prevent this danger the development of a new technology called “digital information hiding” was developed in such a way that the intruder cannot notice the existence of secret information in the media.In this project an image steganograph system is introduced. The proposed system is based on using the affine transform to represent the blocks of the secret image in terms of the blocks of the cover image. Then, the least significant bits (LSB) insertion method is utilized to hide the quantized affine transform coefficients of the secret image in the cover image. Also in this research some block indexing methods are utilized to improve (i.e, speed up) the involved trials of affine mappings. Three systems (they are traditional IFS, IFS with symmetry predictions, and IFS with symmetry prediction and blocks indexing) have been established. They used to manage the way of selecting the suitable domain (cover) to represent the range (secret) block. The domain search operation will not need to make all isometric - block tests on each domain block. The best domain isometric state is assessed using the introduced isometric predictor; which is based on the moment status of the matched block. This will significantly reduce the matching time because only one match, instead of eight, will be tested to evaluate the IFS - similarity between any range and domain block. Also, a block indexing method is introduced to filter the domain blocks, and filter - in only those domain blocks that have similar block index with that of the mapped range block to be tested using IFS - matching.Some of the well known fidelity measures (like, MSE and PSNR) have been used to asses the quality of the reconstructed image. The conducted test results indicated that the proposed improvements have reduced the required hiding time down to 6.81 second (around 80 times in comparison with the traditional scheme) without making significant degradation in image quality
