NeighShrink is an efficient image denoising algorithm based on the discrete wavelet
transform (DWT). Its disadvantage is to use a suboptimal universal threshold and identical
neighbouring window size in all wavelet subbands. Dengwen and Wengang proposed an
improved method, which can determine an optimal threshold and neighbouring window size
for every subband by the Stein’s unbiased risk estimate (SURE). Its denoising performance is
considerably superior to NeighShrink and also outperforms SURE-LET, which is an up-todate
denoising algorithm based on the SURE. In this paper different wavelet transform
families are used with this improved method, the results show that Haar wavelet has the
lowest performance among

Many researchers consider Homogeneous Charge Compression Ignition (HCCI) engine mode as a promising alternative to combustion in Spark Ignition and Compression Ignition Engines. The HCCI engine runs on lean mixtures of fuel and air, and the combustion is produced from the fuel autoignition instead of ignited by a spark. This combustion mode was investigated in this paper. A variable compression ratio, spark ignition engine type TD110 was used in the experiments. The tested fuel was Iraqi conventional gasoline (ON=82).

The results showed that HCCI engine can run in very lean equivalence ratios. The brake specific fuel consumption was reduced about 28% compared with a spark ignition engine. The experimental tests showed that the em

The current research aims to identify the perceptual speed of the university students as well as to identify the differences in the level of perceptual speed for the university students according to the variables of (male, female) specialization (scientific, human) university (Baghdad, Mustansiriya). Additionally, the research aims to identify the prevalence of emotional pattern and to identify the relationship between perceptual speed and the emotional patterns among university students. The researcher designed a questionnaire to measure the Emotional Patterns based on Jerome Freedman perspective. As for perceptual speed, the researcher adopted French, Extrom and Price scale (1963), which was tran

يعاني كل منا في فترة من فترات حياته من النقص في نواحي مختلفة ربما ينتهي هذا الشعور بعد فترة وربما يبقى لفترة من الوقت الا ان من المهم التعرف فيما اذا كان هذا الشعور ذأ تأثير ايجابي او سلبي ونقصد به اذا كان ايجابيا فان الفرد سيحاول تعويض هذا النقص بشكل يطور فيه نفسه وقدراته لسد هذا النقص بينما السلبي فان الفرد قد يلجأ الى الانتقام او ايذاء الاخرين بسبب هذا الشعور مع ما يرافق هذا الشعور من انخفاض في تقدير الذ

لما كانت العلاقه بين الاولاد  ووالديهم  مؤثره في تحديد شخصيتهم وتطويرهم اجتماعيا , اصبح من الضروري ان ندرك بان هناك انواع مختلفه من اساليب المعامله الوالديه لكن الشائع عن اسلوب التنشئه الوالديه في العراق هو الاسلوب التسلطي الذي يفرض فيه الاب بالذات اكثر من الام اراء  ومعتقدات ويتحكم في اتخاذ القرارات نيابه عن الابناء وحتى عن الزوجه في كثير من الاحيان وقلما يتنازل الاب عن هذه الحقوق . انه

One of the important goals in the learning process is to be effective learning through the self-direction of the learner , because it has an impact on the effort of learners , it is better to be a learner responsible for learning and independent of the acquisition of knowledge ,

The current research was aimed at the following:
1. Measurement of Personality Type Observer of the University students.
2. Identify the differences in Personality Type Observer among the University students according to variable of Sex (male / female). And according to variable of Specialization (scientific / literary)
3. Measurement of Withdrawal of the University students.
4. Identify the differences in Withdrawal among the University students according to variable of Sex (male / female). And according to variable of Specialization (scientific / literary).
5. Identify the relationship between Personality Type Observer and Withdrawal.
To achieve this aims of the research, the researchers set up the instrument is scale

أن بناء الشخصية القادرة على التفاعل والتأثير في معطيات الحضارة ، والتقدم في مسالكها المتطورة ، بات هدفا لكل مجتمع يريد الوصول إلى مصاف الدول المتقدمة
(رسول ، 1984، ص7) وبالأخص في مجتمعنا الذي يمتلك مقومات المجتمعات المتحضرة ، فظهر الاهتمام بالدوافع التي تدفع الأفراد نحو مزيد من العطاء والإنجاز وتساعد في بناء شخصية قوية قادرة على تحقيق ما تصبو أليه من أهداف وطموحات ، ومتمتعة

Education, who is dignified the community and transmit a stagnation to the movement and chaos into
the system of the advancement and nettlesome to the production, so it is the human resource development focus
of the overall development, as that man in general and university student in particular is a tool and purpose of
development together, there is no development without human From this perspective the researcher felt there
was a need to conduct a study to know the psychological stability among the students of the university and the
detection level of ambition, the following specific question? What is the relationship between the psychological
stability level with the ambition among the students of the university?
