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.

Background:The paper deals with a diesel common rail nozzle in which a novel orifice layout is implemented.Objective:Its influence on the nozzle mechanical-hydraulic behavior and on the spray shape transient development is experimentally investigated.Methods:In the research, a solenoid injector for light duty diesel engines is equipped with the novel nozzle prototype and tested. The prototype layout is described, pointing out the features of the nozzle orifices, in which a Slot cross-section is adopted; the investigation is accomplished extending the hydraulic tests and the spray visualizations to a reference nozzle with standard holes. The influence of the hole layout on the mechanical-hydraulic behavior of the nozzle is assessed by experimental analysis based on the rate of injection measurement, in comparison with the reference nozzle. Once the hydraulic behavior of the novel nozzle has been characterized in terms of mass flow rate, the slot influence on the spray shape is assessed analyzing the macroscopic features such as the penetration distance and the spray angle, in non evaporative conditions. The study is carried out under transient injection conditions, for different injection pressures, up to 1400 bar.Results:The results on spray characteristics also provide reference information to set up spray models suited to take the Slot orifice into account.
