Legal considerations for using digital twins in additive manufacture a review of the literature

Rapid technological change presents new opportunities and reveals new risks, challenging existing governance arrangements. The fusion of Industry 4.0 technologies combines with Additive Manufacturing (AM) to create new business solutions. Legal issues with AM are well documented, for example Daly[1] explores the interaction of 3D printing with the law, identifying Intellectual Property, Product Liability and Data Privacy as areas of importance. However, this technology fusion has also enabled improved real-time digital representation, monitoring, simulation and control of the physical delivered through applications of Digital Twin. Such Digital Twins are prevalent in manufacturing and in AM can potentially provide assurance that a printed item meets specified requirements. However, additional legal considerations are emerging. This paper illustrates these by examining the attributes of "Digital Twins in Additive Manufacture Use Cases" revealed through literature

Dos aniversarios paralelos: José Garnelo y Ángel Díaz Huertas (1866-2016)

En 2016 conmemoramos el 150 aniversario del nacimiento de dos fi-guras fundamentales para la plástica en España, que desarrollaron sus respectivas trayectorias artísticas complementando su actividad creativa como pintores con iniciativas profesionales adicionales, pero no por ello menos relevantes: José Garnelo, como reformador educativo de las propias enseñanzas artísticas, como ensayista y promotor de revistas sobre arte; y Ángel Díaz Huertas, como pintor-ilustrador, en una época en la que, enlazando con los postulados del romanticismo y acomodándose a los nuevos posicionamientos estéticos, la prensa y las artes gráficas vivieron un auténtico auge, que fue esencial para la generalización y democratización de la culturaIn 2016 we commemorated the 150th anniversary of the birth of two leading figures for visual arts in Spain, who developed their respective artistic careers complementing their creative activity as painters with additional, but not less relevant, professional initiatives: José Garnelo, as an instructive reformer of art education, as an essayist and promoter of art magazines; and Ángel Díaz Huertas, as a painter and illustrator, at a time when, connecting with romantic postulates and adapting to the new aest-hetic trends, the press as well as graphic arts reached a new height, which was essential for the generalization and the democratization of culture

LABORATORY MEASUREMENTS OF THE K-SHELL TRANSITION ENERGIES IN L-SHELL IONS OF SI AND S

We have measured the energies of the strongest 1s–2ℓ (ℓ = s, p) transitions in He- through Ne-like silicon and sulfur ions to an accuracy of <1 eV using the Lawrence Livermore National Laboratory's electron beam ion traps, EBIT-I and SuperEBIT, and the NASA/GSFC EBIT Calorimeter Spectrometer (ECS). We identify and measure the energies of 18 and 21 X-ray features from silicon and sulfur, respectively. The results are compared to new Flexible Atomic Code calculations and to semi-relativistic Hartree–Fock calculations by Palmeri et al. (2008). These results will be especially useful for wind diagnostics in high-mass X-ray binaries, such as Vela X-1 and Cygnus X-1, where high-resolution spectral measurements using Chandra's high-energy transmission grating has made it possible to measure Doppler shifts of 100 km s[superscript -1]. The accuracy of our measurements is consistent with that needed to analyze Chandra observations, exceeding Chandra's 100 km s[superscript -1] limit. Hence, the results presented here not only provide benchmarks for theory, but also accurate rest energies that can be used to determine the bulk motion of material in astrophysical sources. We show the usefulness of our results by applying them to redetermine Doppler shifts from Chandra observations of Vela X-1.United States.
