A computed tomography problem as a 3D reconstruction of density distribution is considered. The input data are obtained as a result of irradiations. The solution of the computed tomography problem is presented as a set of cross-section images. The reconstruction in a single cross-section is performed by algorithm of convolution and back projection. The parallelization is fulfilled over a set of cross-sections by use of the MPI technology.

This article applies both single cross-section and dual cross-section approaches to modeling the propensity to be self-employed among the foreign born in the Australian labor market. The results from a single cross-section regression indicate that educational attainment, Australian labor market experience, the availability of capital, marital status and job related characteristics are important influences on self-employment outcomes. The propensity to be self-employed among immigrants is shown to be enhanced by the existence of enclave markets. Ethnic enclaves created via a common language provide more relevant prospects for self-employment than does the concentration of immigrants by birthplace. However, enclave markets do not have a significant impact on the self-employment outcomes of the Australian-born children of immigrants. The dual cross-section approach shows that the cross-section self-employment growth among immigrants is predominantly an adjustment effect rather than a cohort effect.

We explain the proliferation of panel data studies in terms of (i) data availability; (ii) the heightened capacity for modeling the complexity of human behavior than a single cross-section or time series data can possibly allow; and (iii) challenging methodology. Advantages and issues of panel data modeling are also discussed.

In this paper, a Section Tool Module is built to implement the cross section design of vehicle pillar structures which is integrated in VCD (Vehicle Concept Design) system [1]. The module may lead engineers to create section database and to get proper design plan effectively. The sectional properties such as area, moments of inertia are generated. In addition, an optimal design technique applied in this module is presented to perform the optimization for single cross section, in which sectional property is defined as objective function. An example of the optimization for a single cross section which is extracted from a passenger car is shown to demonstrate the Section Tool Module.

Composite roughness is an important parameter in river hydraulic calculations. In this paper, various typical methods for predicting composite roughness of river were summarized, including Einstein Method, Lotter Method, JIANG Method and Weighted Average Method, their theoretical rigors were discussed from both perspectives of minimum energy dissipation principle and analytical analysis, and their calculation precisions were verified by a large number of flume test data. Research shows that Einstein Method complies with the principle of minimum energy dissipation, also is the necessary and sufficient condition of resistance equation having unique solution, and its calculation precision is higher, therefore, Einstein Method is more suitable for composite resistance calculation of river with single cross section.

Innovations in the field of telecommunications and technological development in information processing affect the provision of public services. One of the main priorities of governments is to achieve greater efficiency in the provision of public services and e-government is one of several measures implemented. Our study aims to determine how e-government and efficiency affects the provision of public services in general, and also by functions. We apply a different model to calculate efficiency of the provision of public services and by function. Our empirical analysis, which included correlation and multiple linear regressions, was applied in 2012-2014 for a single cross-section of 35 economies. The results show a significant relationship between e-government and efficiency. Furthermore, we obtain a significant relation between Online Services, Telecommunication Infrastructure and Human Capital with efficiency in the provision of public services.
