The Iraqi government adopted several projects in the previous years to implement e-government in providing services to citizens, but many obstacles have greatly influenced and delayed the carrying out of this aim. Economics, societal issues, and a lack of infrastructure are all potential obstacles. As a result, there is no unified system for e-government based on spatial data that will provide outstanding service to the users. This article adopted the government-to-citizen G2C and government-to-government G2G model to create a mobile spatial data application for maintenance and repair workshops MRW in Baghdad city based on the geodatabase of industrial services using the Appsheet platform as a developing portal in addition to the ArcGIS online technique from ESRI to create interactive web maps. The results of the article involve two models. Firstly, the G2C model display geoinformation and non-spatial data on satellite images for 14925 maintenance and repair workshops classified into 148 careers according to the law of industrial services management rule 30 for 2000 in Baghdad city to provide services for the individuals. Secondly, the G2G model involves creating an interactive web map of the spatial distribution of MRW for all Iraqi provinces and statistics to support the researchers and decision-makers.

In our research, we will present three reduction strategies for calculating the reliability of complex networks. In the first method we systematically update every parallel path via an equal single path, and ultimately lessen the given system to one together with most effective series detail, which is called reduction to series elements. The second is the decomposition method which is an application of the law of total probability that includes choosing a key component and then calculating the reliability of the network when the key failed once and the second time the key succeeded. These two probabilities are then blended to obtain the reliability of the system. And the third method is the delta-star transformation. All of these methods convert a complex network into simple network. [ABSTRACT FROM AUTHOR]

This study explains the influence of secondary filler on the dispersion of carbon nanotube (CNT) reinforced high density polyethylene (HDPE) nanocomposites (CNT/HDPE). In order to understand the mixed-fillers system, Montmorillonite (MMT) was added to CNT/HDPE nanocomposites. It was followed by investigating their effect on the thermal, mechanical and XRD properties of the aforesaid nanocomposite. Incorporation of 3 wt% each of MMT into CNT/HDPE nanocomposite resulted to the increased values for the tensile and flexural strength, as compared to the pure HDPE matrix. The thermal analysis result showed improved thermal stability of the formulated nanocomposites. [ABSTRACT FROM AUTHOR]
