Atomic force microscope (AFM) based anodization nanolithography on semiconducting layers is a useful tool for nanoscale fabrication. A custom AFM patterning technique has been created that couples CAD with the lithographic capabilities of the AFM. Designed nanostructures to be deposited on a silicon substrate are rendered as a three-dimensional model using CAD. AFM based anodization nanolithography is then used to replicate the features at the nanoscale using automated voltage bias and humidity modulation as prescribed by the model and dictated by the system. The work presented outlines the advantages and limitations when three-dimensional modeling is combined with nanoscale lithography using an AFM.

The aim of this work is to create a three-dimensional model of a new speed change control device using an engineering CAD system Solidworks. In particular, the article describes the methods of computer construction of a three-dimensional model of a rotary stopper in the form of a closed-loop hydraulic system of the device for smooth control of speed changes through a gear differential. The control link can be either a ring gear, or a carrier, or a sun gear. Ways of creating new parts of the device, use of elements from standard libraries and coordination of their dimensions in assembly have been considered. The ability to parameterize the dimensions allows you to automate the creation of both a single part and the whole device of a particular design, based on the specified source data. The application of special meshes for modeling movable and fixed joints allows you to correctly place the parts, control the correctness of their assembly, and then conduct kinematic and power studies of the device, animate its elements in motion. It has been concluded that the use of computer three-dimensional modeling in the design of such stoppers allows: at the initial stage of design to get a visual idea of the stopper of rotational motion; use a computer to view the created model from any point; easy to edit three-dimensional models, i.e. make the necessary changes; achieve great savings in time and design costs; get a large number of possible design solutions that need to be analyzed in detail and in depth to choose the rational, i.e. the best fit. The created model of the stopper of rotational movement allows to choose the optimal place of its installation in a gear differential of the device of speed change from the point of view of use of the minimum sizes and volume. Based on this, computer simulation must precede design. Keywords: three-dimensional modeling; rotary stopper; closed-loop hydraulic system; gear differential

Most previous three-dimensional modeling work in gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW) focuses on the weld pool. Almost all three-dimensional weld pool models are based on the two-dimensional axisymmetric Gaussian assumption of plasma arc pressure and heat flux. In this paper the three-dimensional plasma arc is modeled and results are presented. The velocity, pressure, temperature, current density, and magnetic field of the plasma arc are computed by solving the conservation equations of mass, momentum, and energy, as well as part of Maxwell's equations. This three-dimensional model allows one to study the non-axisymmetric plasma arc caused by external perturbations such as the external magnetic field. It also provides more accurate boundary conditions when modeling the welding pool. The future work is to unify it with the weld pool model and accomplish a complete three-dimensional model of GTAW and GMAW.

This article provides a detailed account of the process of scanning, post-processing and further manipulation of three-dimensional models obtained with structured light scanners. Purpose. The purpose of the study is determined by the need for national archaeologists to learn the methods of three-dimensional modeling for the implementation of scientific research corresponding to international standards. Unfortunately, this direction in national archaeology began to develop in a relatively recent time and there is a lag in the application of three-dimensional modeling of national archaeology compared to the world level. Results. Any archaeological, experimental or ethnographic artifact can be used for three-dimensional scanning. To perform post-processing of three-dimensional models it is necessary to carry out primary scanning of an artifact by one of the existing algorithms. The algorithm for creating models, their positioning, simplification, saving in various formats and export is described. The main sequence of 3D models post-processing includes: processing of groups of scanned projections (their cleaning and alignment), creation of artifact model and processing/rectification of the resulting model using special software. Conclusion. As a result of correct implementation of the algorithm, the researcher receives a scaled model completely corresponding to the original artifact. Obtaining a scalable, texture-free three-dimensional model of the artifact, which fully corresponds to the original and exceeds a photograph in the quality of detail transfer, allows a scientist to conduct precise metric measurements and any procedures of non-invasive manipulation of the models. The ability to access a database of three-dimensional models of archaeological collections greatly simplifies the work of archaeologists, especially in situations when country borders are closed.

In order to study the evolution and metallogenic regularity of MVT lead-zinc deposits in western portion of Hunan province (China), two sets of three-dimensional model are established by Minexplorer software: 3D model in typical deposit and 3Dmodel on regional scale. On the basis of synthetic analyses of two sets of models, the further prospecting should be focused on the north part of ore-bearing layer along the Huayuan-Zhangjiajie fault belt. It is effective to observe occurrence and distribution characteristics from the 3D geological model, and to provide the basis for further exploration prospecting of the concealed deposits.
