Stability testing of time series data for CT Large industrial establishments in Iraq

Abstract: -
The concept of joint integration of important concepts in macroeconomic application, the idea of ​​cointegration is due to the Granger (1981), and he explained it in detail in Granger and Engle in Econometrica (1987). The introduction of the joint analysis of integration in econometrics in the mid-eighties of the last century, is one of the most important developments in the experimental method for modeling, and the advantage is simply the account and use it only needs to familiarize them selves with ordinary least squares.

Cointegration seen relations equilibrium time series in the long run, even if it contained all the sequences on the direction of random (non-static, and variables integrated of degree one), they although no sleep will move close together over time and be the difference, including a finger (1), thus the idea of ​​joint integration simulates a balance in the long run to interpret the economic system, is concentrated the main reason for the lack of balance in the inability of economic agents to adapt to economic agents with the information on the fly (2). There are an estimated cost of adaptation and that lead to determining the value of the dependent variable only through the value of current and past some of the independent variables in addition to the evolution of the dependent variable as a result of its interaction with the values ​​of the independent variables current and previous as well as the delay of the variable's in the form of short-term (dynamic). The addition of dependent variables with a delay to the form simplification of the model motor (which tend otherwise to the existence of a strong correlation between the independent variables with a delay) when the restriction (adaptation) values ​​of the dependent variable the current values ​​of the independent variables of delay works to reduce these limits in return for the cost of the border with delay.

On this basis, the application of the methodology, the researcher Engle - Granger (Engle - Granger) in the joint integration of the CT data models for large industrial plants in Iraq for the period (1990-2005) was cross-

sections so that the sector (public, private)

Where the research contained in the theoretical side Mbgesan, in the first part, has been the research methodology by showing the importance of research, which confirmed the account the new addition to the specialists and researchers in this field. The research problem can be summarized in the impact of the application of this method compared to compact way of least squares for fixed effects for the periods and groups, as well as the goal of the research and its premises and the nature of the variables used and where they overlap.

In the second section, the researcher introduced the concept of stability, and how to test the method of combining CT data and time series.
In the practical side, were presented results of the assessment of the variables used in the research and for the period (1990-2005), disaggregated by estimation method and the type of the function of each sector (public, private) separately.

Finally Showing researcher conclusions and recommendations reached by the research.

Bayes Classification and Entropy Discretization of Large Datasets using Multi-Resolution Data Aggregation

Big data analysis has important applications in many areas such as sensor networks and connected healthcare. High volume and velocity of big data bring many challenges to data analysis. One possible solution is to summarize the data and provides a manageable data structure to hold a scalable summarization of data for efficient and effective analysis. This research extends our previous work on developing an effective technique to create, organize, access, and maintain summarization of big data and develops algorithms for Bayes classification and entropy discretization of large data sets using the multi-resolution data summarization structure. Bayes classification and data discretization play essential roles in many learning algorithms such a

A Comparative Study of Some Methods of Estimating Robust Variance Covariance Matrix of the Parameters Estimated by (OLS) in Cross-Sectional Data

 

Abstract

The Classical Normal Linear Regression Model Based on Several hypotheses, one of them is Heteroscedasticity as it is known that the wing of least squares method (OLS), under the existence of these two problems make the estimators, lose their desirable properties, in addition the statistical inference becomes unaccepted table. According that we put tow alternative,  the first one is  (Generalized Least Square) Which is denoted by (GLS), and the second alternative is to (Robust covariance matrix estimation) the estimated parameters method(OLS), and that the way (GLS) method neat and certified, if the capabilities (Efficient) and the statistical inference Thread on the basis of an acceptable

Recovery of Aluminum from Industrial Waste (Slag) by Melting and Electrorefining Processes

Slag of aluminum is a residue which results during the melting process of primary and secondary aluminum production. Salt slag of aluminum is hazardous solid waste according to the European Catalogue for Hazardous Wastes. Hence, recovery of aluminum not only saves the environment, but also has advantages of financial and economic returns. In this research, aluminum was recovered and purified from the industrial wastes generated as waste from both of State Company for Electrical and Electronic Industries (Baghdad/AlWaziriya) and General Company for Mechanical Industries (Babylon/-Al-Escandria). It was found that these wastes contain tiny proportions of other elements such as iron, copper, nickel, titanium, lead, and potassium. Wastes were

Industrial Property Licensing Contracts are Exempted from Ban in Accordance with USA and European Law

Intellectual property rights of all kinds، and their nature، are considered a tool in the hands of their owner that enables him to monopolize the benefits that you confer on them without any dispute or mediation from anyone. Intellectual property on its intellectual product، and preventing others from exploiting it without obtaining the permission of its owner All of this is reflected positively on the progress of the industrial and commercial field، and this justifies the protection provided by the laws regulating intellectual property rights to its owner، whether at the national or international level، and with our recognition of the right of the owner of intellectual property rights to enjoy the exclusive use of his right، and

Data Base for Dynamic Soil Properties of Seismic Active Zones in Iraq

Iraq is located near the northern tip of the Arabian plate, which is advancing northwards relative to the Eurasian plate, and is predictably, a tectonically active country. Seismic activity in Iraq increased significantly during the last decade. So structural and geotechnical engineers have been giving increasing attention to the design of buildings for earthquake resistance. Dynamic properties play a vital role in the design of structures subjected to seismic load. The main objective of this study is to prepare a data base for the dynamic properties of different soils in seismic active zones in Iraq using the results of cross hole and down hole tests. From the data base collected it has been observed that the average ve

Determination of Optimal Time-Average Wind Speed Data in the Southern Part of Malaysia

Mersing is one of the places that have the potential for wind power development in Malaysia. Researchers often suggest it as an ideal place for generating electricity from wind power. However, before a location is chosen, several factors need to be considered. By analyzing the location ahead of time, resource waste can be avoided and maximum profitability to various parties can be realized. For this study, the focus is to identify the distribution of the wind speed of Mersing and to determine the optimal average of wind speed. This study is critical because the wind speed data for any region has its distribution. It changes daily and by season. Moreover, no determination has been made regarding selecting the average wind speed used for w

Stability of the Finite Difference Methods of Fractional Partial Differential Equations Using Fourier Series Approach

The fractional order partial differential equations (FPDEs) are generalizations of classical partial differential equations (PDEs). In this paper we examine the stability of the explicit and implicit finite difference methods to solve the initial-boundary value problem of the hyperbolic for one-sided and two sided fractional order partial differential equations (FPDEs). The stability (and convergence) result of this problem is discussed by using the Fourier series method (Von Neumanns Method).
