مقارنة بعض المقدّرات الحصينة في دوال التمييز بأستخدام المحاكاة

The development in manufacturing computers from both (Hardware and Software) sides, make complicated robust estimators became computable and gave us new way of dealing with the data, when classical discriminant methods failed in achieving its optimal properties especially when data contains a percentage of outliers. Thus, the inability to have the minimum probability of misclassification. The research aim to compare robust estimators which are resistant to outlier influence like robust H estimator, robust S estimator and robust MCD estimator, also robustify misclassification probability with showing outlier influence on the percentage of misclassification when using classical methods. ,the other aim of research is to compare estimators to find the best estimator which can gave less probability of misclassification especially with the variety of contamination percentage and different samples sizes and the data contaminated according to a technique that had never been used in other research on the country level.

تقدير دالة الأنحدار اللامعلمي باستخدام بعض الطرائق اللامعلمية الرتيبة

المستخلـص

تم في هذا البحث دراسة الطرائق اللامعلمية الرتيبة لتقدير دالة الأنحدار اللامعلمي، ومعالجة القيم الشاذة الموجودة في دالة الأنحدار اللامعلمي لجعل الدالة رتيبة (متزايدة أو متناقصة).

لذا سنقوم أولاً بتقدير دالة الأنحدار اللامعلمي بإستخدام ممهد Kernel ومن ثم تطبيق الطرائق الرتيبة لجعل الدالة متزايدة إذ سنتناول ثلاث طرائق للتقدير:-

تأثير بعض مستخلصات الايثر النفطي لنباتي اكليل الجبل وعرق السوس في نمو بعض أنواع الفطريات الممرضة للنباتات

Abstract The study aims to evaluate antifungal activity of petroleum ether extracts from leaves and stems of Rosmarinus officinalis and root of Glycerrhiza glabra , against fungi Fusarium oxysporium , Aspergillus flavus and Penicillium expansum. While the results of sensitivity of the fungi towards petroleum ether extracts showed different activity, petroleum ether extract of Rosmarinus officinalis showed more activity on Aspergillus flavus minimum inhibitory concentration(MIC) was 25 mg /ml and minimum fungicide concentration(MFC) was 37.5 mg /ml, followed by Fusarium oxysporium, (MIC) was 50 mg /ml and (MFC) was 37.5 mg /ml, finally Penicillium expansum (MIC) was 50 mg /ml and (MFC) was 75 mg /ml, used more concentration from petroleum et

مقارنة بين دالة الإنتماء ودالة الأنتروبي في الإنحدار الخطي الضبابي المكيف

Abstract

       There are many uncertainty sources that may affect the statistical reasoning. However, traditional methods can not deal with all kinds of uncertainty sources, which has led many researchers to develop traditional methods. Studies still exist to this day, making hypotheses to create a common understanding for the purpose of reaching new solutions through the use of new methods that combine traditional and modern theories of sources of uncertainty

       The aim of current study was to develop the adaptive fuzzy linear regression model in the case of using inaccurate data as the source of uncertainty. Specifically, the

Using Genetic Algorithm to Estimate the Parameters of the Gumbel Distribution Function by Simulation

In this research, the focus was on estimating the parameters on (min- Gumbel distribution), using the maximum likelihood method and the Bayes method. The genetic algorithmmethod was employed in estimating the parameters of the maximum likelihood method as well as  the Bayes method. The comparison was made using the mean error squares (MSE), where the best  estimator  is the one who has the least mean squared error. It was noted that the best estimator was (BLG_GE).

The impact of exceptional circumstances on personal freedoms: دراسة مقارنة

The safety of state may be threatened by the exceptional circumstances such as the wars and normal disasters. Those circumstances make the state unable to protect the general system by using public rules. So the authority of control organization should expand to control such circumstances. Those authorities should report hasty and definitive steps to encounter such issues. The exceptional circumstances may directly affect the personal rights and freedom that were warranted by the constitution. So the legislator should determine the constraints that were adopted upon them and showed the guarantees of those liberties in order to avoid the unfair decisions and orders.
