    Software for full-color 3D reconstruction of the biological tissues internal structure

    Full text link
    A software for processing sets of full-color images of biological tissue histological sections is developed. We used histological sections obtained by the method of high-precision layer-by-layer grinding of frozen biological tissues. The software allows restoring the image of the tissue for an arbitrary cross-section of the tissue sample. Thus, our method is designed to create a full-color 3D reconstruction of the biological tissue structure. The resolution of 3D reconstruction is determined by the quality of the initial histological sections. The newly developed technology available to us provides a resolution of up to 5 - 10 {\mu}m in three dimensions.Comment: 11 pages, 8 figure

    The VisualYzARt project intends to develop research on mobile platforms, web and social scenarios in order to bring augmented reality and natural interaction for the general public, aiming to study and validate the adequacy of YVision platform in various fields of activity such as digital arts, design, education, culture and leisure. The VisualYzARt project members analysed the components available in YVision platform and are defining new ones that allow the creation of applications to a chosen activity, effectively adding a new language to the domain YVision. In this paper we will present the role of the InstitutoPolitécnico de Santarém which falls into the field of education.VisualYzART is funded by QREN – Sistema de Incentivos à Investigação e Desenvolvimento Tecnológico (SI I&DT), Project n. º 23201 - VisualYzARt (from January 2013 to December 2014).

    Nothing in the world happens without innovations: new ideas, new products, and new solutions of the existing problems. Without science, technologies, engineering and STEM there will be no innovations. Development of STEM education has fundamental importance for development of modern information society. Even today in Ukraine the process of introduction of STEM and STEAM in education gains the increasing value. Training courses dealing with questions of Internet of things, built-in systems and other directions of modern engineering take root in higher education institutions. An example of such training course is training of students of various specialties of 3D printing technology and formation of skills of the use of these technologies for the creation of own innovative projects within their professional competences. Possibilities of the use of 3D printing in educational activity are presented in the article. The analysis of experience of STEM and STEAM education in other countries is carried out

    New software for comparing the color gamuts generated by printing technologies

    In the color industry, it is vital to know the color gamut of a given device. Several tools for visualizing and comparing color gamuts are available but they each have some drawbacks. Therefore, the aim of this work was to develop and validate new software for comparing the color gamuts generated by printing devices; we also developed an automated color measurement system. The software simultaneously represents the gamuts in the 3D CIELAB space. It also calculates the Gamut Comparison Index and the volume using two algorithms (Convex Hull and Alpha Shapes). To evaluate the performance of our software, we first compared the results it obtained for the color gamuts with those from other comparison methods such as representation in the CIE 1931 chromaticity diagram or other color spaces. Next, we used Interactive Color Correction in 3 Dimensions (ICC3D) software to compare the gamut representations and volumes. Our software allowed us to identify differences between color gamuts that were not discriminated by other methods. This new software will enable the study and comparison of gamuts generated by different printing technologies and using different printing substrates, International Color Consortium profiles, inks, and light sources, thereby helping to achieve high quality color images.Optics Group (FQM151, University of Granada)University of Granada (pre-doctoral contract, Training Programme for Research Staff, FPU)Funding for open access charge: University of Granada/CBU

    3D Printed NMR Spectra: From 1D and 2D Acquisition to 3D Visualization

    Get PDF
    Visualization of two- dimensional and relaxation NMR spectra can be difficult for students new to the subject. Educators have utilized 3D printing previously to demonstrate concepts such as potential energy surfaces and molecular orbitals, but this technology has yet to be used to create a visual model of NMR data. In order to address this, we have developed an approach for creating 3D printed models of two- dimensional and inversion recovery spectra, which can then be used as an innovative teaching tool. This was done by converting raw FT NMR data into a 3D data graph using Mathematica. This graph is then converted into stereolithography format and printed using a 3D printer. These physical models will allow students to better understand the complex information presented in these NMR spectra
