Bandoneon!

Bandoneon! (a combine), performed in October 1966 as part of the 9 Evenings: Theatre and Engineering, has been regarded as Tudor’s first work as a composer. However, the conception of this piece was not only directly influenced by two other amplified bandoneon pieces he realized in the same year, Gordon Mumma’s Mesa and Lowell Cross’s Musica Instrumentalis, but had also started off as a realization of a “Mobius-Strip” composition by Mauricio Kagel. Moreover, most of the modular electronics in his setup were also used in other realizations around the same period. The true difference lies in how these common materials were used and to what ends. What the self-proclaimed effort to make a “giant white noise generator” from scratch brings to the fore is a synecdochical relationship between the modular instruments used and the larger instrumental complex they compose. The investigation of this coordination between the parts and the whole reveals a strange disappearance of an entire group of instruments considered central to the performance, a mystery that highlights the peculiar nature of Tudor’s “composition.”

Development of a block system for controlling the main parameters of the seed separation process based on air-gravity machines

The paper presents the development of a program for controlling the main parameters of the separation process in the industrial automation instrumental complex CODESYS V3. Also the visualization of the control panel was developed. Based on this, a control unit was assembled with the presented version of the software visualization for controlling the main parameters of the air-gravity machine.

Knowledge-Oriented Tool Complex Processing Databases of Scientific Publications

Introduction. Nowadays, numerous applications and tools are known that implement information retrieval technologies in various text sources in accordance with specified parameters. Moreover, the search results are provided to the user for each search parameter individually and not related to each other. And the application of Semantic Web technologies for the purpose of multi-parameter and related information retrieval in various sources in Ukraine is at the initial stage of development. A separate problem is the multimedia presentation of search results and their comparison with the conceptual structure of the domain of interest (Knowledge Domain) with the goal of extracting new knowledge. From this point of view, it is relevant for scientific research to process the scientific publications of one author, authors of a scientific unit and the academic institute as a whole, using the Semantic Web technologies, multimedia presentation of information, and effective support for the process of extracting new knowledge. Purpose. Designing the architecture and functioning algorithms of the instrumental complex for processing databases of scientific publications, as well as developing examples of using a formal description of a scientific article with a number of queries. Methods. The methods and models used in this work are based on Semantic Web information technologies focused on the development and use of subject ontologies. Ontologies are the basic components of these technologies both for conducting scientific research and creating large databases, including scientific publications of the authors. Results. The architecture of the instrumental complex for processing databases of scientific publications and the algorithms for its functioning at the preparatory and main stages have been developed. Examples of queries to the database of scientific publications that demonstrate the performance of IR are given. Conclusion. The article discusses the architecture of the instrumental complex for processing databases of scientific publications and the algorithms for its functioning at the preparatory and main stages. The steps of the preparatory phase, which are implemented by the knowledge engineer, are examined in detail. At the same time, the creation of two ontology models of the scientific article with the presentation of the corresponding ontographs was highlighted: the CRF-model describes the concepts contained in the article, and the OWL-model describes the structural components of the article. In conclusion, examples of queries to the databases of scientific publications are presented, demonstrating the performance of the instrumental complex. Further, it is necessary to expand the use in the development of IR technologies, such as cognitive semantics and graphics, multimedia presentation of information, focused on the effective support of the processes of extraction and/or generation of new knowledge.

TOOLKIT FOR IMMERSIVE VIRTUAL SIMULATORS WITH BIOFEEDBACK

The architecture of the instrumental complex for the creation and reproduction of immersive virtual simulators using biological feedback is proposed. An overview of existing solutions such as tools for the development and reproduction of virtual simulators is considered. The analysis of the use of virtual reality in different areas such as aircraft control, parachute jumping, various medical procedures, and operations which require preliminary preparation is considered. The concept of an immersive virtual simulator with biological feedback has been introduced. The use of virtual reality and biological feedback equipment as well as the applicability of the software-hardware complex in the field of interaction and control of objects of the virtual environment based on the state of a person and the state of objects are determined within its framework. The following principles of the instrumental complex development based on the use of the ontological approach are proposed: the use of various mechanisms to describe the learning scenario, the support for various control mechanisms of the simulator, the inclusion of specialists of different profiles in the development process of the simulator, and the automatic generation of the components of the virtual environment based on the declarative model of the virtual simulator to simplify the creation of a virtual environment. The description of the architecture and all interested participants is provided. The connections between the participants and the components of the tool complex are shown. The information and software components of the instrumental complex aimed at automating the process of creation, launch, control, and monitoring based on biological feedback are considered. A complex of ontologies is described: the ontology of an immersive virtual simulator with biological feedback and the ontology of knowledge about human states. The interfaces of the instrumental complex are demonstrated, such as interfaces of the equipment editor, monitoring tools, and launching tools.
