“…Spray forming is used to produce semi-finished mill products in the form of billets, tubes, and sheets through high-rate deposition of atomized powder metal layer-bylayer onto a substrate to form, after their solidification, a bulk product or thick coating. An innovative PM 2 process generating considerable attention is additive manufacturing, a group of fabrication processes through which three-dimensional parts are constructed by adding layers of materials on point, line, or planar surfaces (Hassanin & Jiang, 2015)-i.e., 3D printing using fine-grade metal powders. Metal injection molders are researching potential manufacturing marriages with additive manufacturing processes.…”

The powder metallurgy parts manufacturing (PM 2 ) industry is a significant part of the history of the economy and technology of Pennsylvania. Powder metallurgy parts manufacturing is a process for forming a metal part by compacting metal powder in a die and then heating the compacted powder just below its melting point (called 'sintering'). Powder metallurgy parts manufacturing producers purchase specialized metal powders, lubricants, binders, additives, tooling, process equipment, and industrial gases. Powder metallurgy parts manufacturing producers in north-central Pennsylvania sell most of their PM 2 parts to the automotive industry for use in internal combustion engines. However, the PM 2 industry is adapting its processes for part production in electric vehicles and non-automotive sectors. The small number of specialized suppliers combined with a customer base centered on the automotive industry creates a highly competitive environment among PM 2 firms clustered in the small, rural three-county region of north-central Pennsylvania. Powder metallurgy parts manufacturing in the United States is highly concentrated in this region.

This paper is devoted to the new methods of organizing interactive museum exhibits by means of additive technologies, programmable microelectronics and multimedia. Traditionally museum exhibition is distanced from the visitor appearing just as a visual image. But new trend is to let the visitor inside the exhibition, providing different forms of interactions. Modern museums constantly search for the new ways of presenting cultural and natural heritage taking into account that exhibitions should be at the same time scientifically accurate, attractive, memorable and, ideally, accessible for the wide audience including disabled people. In this regard, tangible user interfaces based on the Internet of Things and combined with the scientific visualization build up very promising set of technologies that brings to live cyberphysical museum exhibits. These exhibits are an alloy of physical museum items with virtual multimedia content, providing the visitor a unique experience of interactivity. The key feature of cyber-physical exhibits is their tangibility, whereby they become accessible for visually impaired people and deliver much more information for the regular visitors. There are a lot of successful attempts to build cyber-physical exhibits within the museum space. However, there is a lack of methodological basis for this, as well as the lack of highlevel tools to seamlessly integrate related technologies into the existing museum infrastructure. In this paper we propose using ontology-driven adaptive multiplatform scientific visualization system SciVi as a software basis for cyber-physical museum exhibits. This system was previously successfully used in solving problems related to steering hardware and software solvers in different application domains, monitoring lightweight robotics systems and supporting custom hardware human-machine interfaces. So, it contains necessary mechanisms to adapt to the third-party digital infrastructure (including the museum one) and build all the required middleware and visualizers within it. We tested our approach by developing two cyber physical exhibits: tangible bonobo skull in the State Darwin Museum (Moscow) and tangible titanophone skulls in the Museum of Permian Antiquities (Perm). Bonobo exhibit appears to be a custom joystick in a form of corresponding skull to steer the Sketchfab-rendered 3D model of bonobo monkey head. Titanophone exhibit allows visitors to discover the age variability of titanophone synapsid in an interactive way.

“…Во-первых, музейные предметы, ввиду их хрупкости, ветхости и/или уникальности, зачастую недопустимо снабжать какими-либо электронными и электромеханическими устройствами, а также недопустимо организовывать прямое (например, тактильное) взаимодействие с ними посетителей. В такой ситуации в роли физических объектов CPS предлагается использовать не сами фондовые экземпляры, а их высокоточные реплики -реконструкции, выполненные посредством аддитивных технологий [2] с применением 3Dсканеров и 3D-принтеров.…”

In this paper we propose an approach to create cyber-physical museum exhibits based on the methods and means of scientific visualization, Internet of things, additive technologies and ontology engineering. Cyber-physical exhibit consists of tightly interconnected virtual and real parts. Scientific visualization is used as methodological and technological basis for presenting the virtual part, which can contain relevant digital content and 3D-reconstructions. Internet of things is a core technology to create tangible interfaces for the corresponding visualization software. Additive technologies allow creating virtual reconstructions and precise copies of museum exhibits. Ontology engineering provides adaptive mechanisms for seamless integration of new cyber-physical exhibits into the existing digital infrastructure of museums. The proposed approach is used in practice to create cyber-physical exhibits in State Darwin Museum (Moscow) and Museum of Permian Antiquities (Perm).
