A Markov – Chain Model for the Tuberculosis in Salah Aldeen City (1991-1999)
- -,
This paper studies a time series for the number of infection of Tuberculosis of the lungs as a Markov chain. We have made hypotheses concerning the number of infections in order to set the problem...

Abdul Majeed Al-Nasir, Hadeel S.Al-Kutubi
We present in this paper Bays method by using Jeffery prior information and new Bayesian using extension of Jeffery prior information for estimating the parameter of exponential distribution and...
Chaotic Analysis of Radial Basis Model
- -,
In this paper, a simulation has been done for the radial basis model of sunspot time series . Chaotic analysis of the simulated data from model, and the study of the chaotic behavior for such a...
Dealing with DirectPlay Environments under DirectX
Aseel Waleed A. Al-Niamey
The idea of this project is based on programming the functions of DirectX, which will connect the last one with the windows, this work is needed because DirectX deals with the hardware and the...
DETECTION AND TREATMENT OF OUTLIERS IN DATA SETS
Tara Ahmed H. Chawsheen, Ivan Subhi Latif
In this paper, we shall try to determine outliers and pinpoint its source of existence by using Box-Whisker plots technique which is an effective approach to detect and treat outliers. Thus the...

- -,
ABSTRACTA comparative study between linear transfer models of low order and ARX model of high order depends on spatial series.The research includes a comparison between efficiency of the different...
New Way to Send Secret Messages Through Electronic Mail
- -,
The secret Electronic Mail messages encounter many problems that causes hacking or modifies it, therefore is necessary to find active ways, to keep it out of hackers and intruders, hiding technique...
Dynamic models for the transfer function and multi inputs
- -,
The importance of Transfer Function Model comes from its use in prediction . The model has been constructed with multi-inputs because of the importance of multi-input in contructing models. Such...
Two New Approaches for PARTAN Method
Ban A. Metras, Khary B. Rasheed
In This paper, we suggest two approaches for the parallel tangent (PARTAN) method. First is to combine PARTAN method with Perry algorithm and second is to combine PARTAN method with...
Comparetive Between Adaptive Filtering And Neural Networks Methods With Application
- -,
The study of time series is one of first important subjects especially with study of analysis behavior of different phenomenons and discussed it throw the historical in different period to...
Using Hidden Markov Chains in Recognition of Vowel Letters in English Language
- -,
This study deals with hidden Markov models . These models consist of sets of finite states , each one of them is associated with a probability distribution . The transition among the states is...
Applications of Kalman and Extended Kalman Filtering to Target Tracking
Basil Y. Thanoon, Basil M.Saied, Khalil S. Al-Wagih
This study deals with the famous trackers named Kalman and extended Kalman filters. This is introduced by describing the state space representation approach to model the target system. A...
Assessment Restricted Liu Estimator to treating Multicollinearity Problem
- -,
In this research, we compared restricted least squares with restricted Liu estimator . by using (MSE) criterion in the existence of multicollinearity. We found that restricted Liu estimator is the...
