Monotonic regression is a nonparametric method designed for application in which the expected value of a response variable increases or decreases in relation to one or more explanatory. One approach is to first apply nonparametric regression to data Estimation of a response variable as a function of two continuous predictor variables is considered and then monotone smooth the initial estimates to ًiron outً violations to the assumed order. Here, such estimators are considered, where local polynomial regression is first used, followed by monotone method using simple averages( SAT) and we use bootstrap procedure and compare by this methods through Monte Carlo simulation using mean – squared error(MSE) . The primary focus of this work is to estimate different types of confidence intervals for these monotone nonparametric regression estimators Most of the confidence intervals use local polynomial regression and resampling methods bootstrap procedure and suggested method and combine between this methods, the methods are then applied for a real data in air pollution field.

Securing web applications is today's most common aspect of securing the enterprise. Web application hacking is on the rise with as many as 80% of cyber attacks done at web application level or via the web. Most corporations have secured their data at the network level, but have overlooked the crucial step of checking whether their web applications are vulnerable to attack. This paper is devoted for presenting a model to protect web pages that acquire passwords and user names against HTML brute force. Along this paper the model will be presented as same as the methodologies of implementation. Algorithms of implementation also will be presented to emphasize the idea where all HTTP packets are trapped and relayed down the stack of the TCP/IP by inserting before HTTP (Port 80) and all HTTP traffic of information that is captured to check for the parameter passing in web and this proposed technique is called Enforcing layer.

The varying length of the 11-year cycle has been found to be strongly correlated with long-term variations of the northern hemisphere land surface air temperature since the beginning of systematic temperature variations from a global network, i.e. during the past 40 years. Comparison of the extended sunspot record with the temperature series confirms the high correlation between sunspot numbers and air temperature, water surface temperature and shows that the relationship has existed through the whole 40 years. Results are compared with field measurements and good correspondence is observed. There is an even better correlation between the lengths of the solar cycle, with years of the highest numbers of sunspots. When the sunspots are minima the temperatures are decreased, and when the sunspots are maxima the temperatures are increased on the earth. There are unusual astronomical Phenomena occur in 2012l (like increase surface air temperature and frequent hurricanes).

In this work, a branch of artificial intelligence was employed to predict the monthly mean of daily air temperature for different target station using the available data of neighboring stations, which were used as the reference stations. The daily air temperature data, collected by the Iraqi Meteorological Office (IMO) for 14 stations, which cover different Iraqi provinces, were used. The long term air temperature data covers the period between 1993 and 2008. These data were classified in parts according to the correlation coefficients relating them. The reference stations data, as on input layer of the neural network and the hidden layers and neurons were defined; the monthly mean of air temperature for the target station was utilized as an output layer of the neural network. Multi-Layer Perceptron’s learning algorithm was applied in present work. The hidden layer and output layer of the network included Sigmoid as an activation function. Finally the interpolated data by (ANN) model were compared with measured data shows very good agreement with Correlation Coefficients (r) ranges between 0.9980 and 0.9767 also Root Mean Square Error (RMSE) ranges from 0.629 °C to 2.221 °C, Mean Percentage Error (MPE) ranges between 0.264 °C and 3.64 °C and Mean Absolute Error (MAE) ranges between 0.367 °C and 1.62 °C for Mosul and Najaf stations respectively.
